The overall effect of restructuring on the LED lighting market

22nd, Jan. 2016
Mingfa Tech Manufacturing Limited

What could be the overall effect of this restructuring on the lighting market? IHS believes that the reorganization could turn the leading lighting manufacturers into pure-play lighting companies that can be more focussed on dynamic markets offering greater growth potential. The restructuring will also allow LED makers to raise capital for further investment, and will likewise let them reduce the hierarchal burden associated with being part of a large conglomerate. This, in turn, could lead to improved margins for the companies—and possibly lower-priced products for consumers.

Light no longer provides illumination alone. LED lighting for indoor positioning, for instance, takes things a step further by sending a basic signal to determine position and help in navigation. Li-Fi, competing with the far more established Wi-Fi, now takes the concept to the next level, using visible LED light for high-speed data transmission of material such as movies, music, or any other form of data.

Packaged LED industry is moving downstream and getting smarte

Some years ago, the senior management at Japanese based chemicals company Nichia suggested it believed that value and leadership in LED lighting would come from quality chips. U.S.-based Cree, meanwhile, stressed that value would increasingly filter down the value chain. Since then, Cree has moved, indeed, in that direction—along with other LED players, such as MLS.

In the last year or two, manufacturers have put increasing emphasis on greater vertical integration, focusing particularly on chip-on-board, modules and light engines. These products have provided an intermediate step in the supply chain between the component LED and a complete lamp or luminaire, and they offer an opportunity for LED manufacturers to diversify and move downstream without going to the extent of producing complete lamps or luminaires.

Moving downstream may be an attractive strategy given the low profit margin for component packaged LEDs and the possibility of Chinese vendors taking a greater share of this market in the future. Many companies, such as Bridgelux, Cree, LG Innotek, Lumileds, Samsung, Seoul Semiconductor and Sharp are supplying these products. Lighting companies, such as Philips and Osram, are also suppliers, as are power/module companies like BAG, Harvard, ULT and Xicato.

Within the smart lighting market there is a trend toward individual luminaire control. One way this can be achieved is by incorporating sensors and controls into the electronics, found at the light engine level. IHS anticipates more engines incorporating smart lighting technologies coming onto the market in 2015, although actual penetration will remain low.

Smart lighting is another way for companies to attempt to add value and improve profit margins. As the LED lighting market moves downstream with modules and light engines, incorporating smart lighting sensors and controls will become, over time, another important part of this trend.


Choosing holder for LEDs

19th, Jan. 2016
Mingfa Tech Manufacturing Limited

LED stands for Light Emitting Diode. These semiconductor diodes emit light when voltage is applied to them. They are used in a variety of applications such as electric lighting, flashlights, traffic lights, streetlights, and alphanumeric displays that appear on digital watches, calculators, and scoreboards, for example. They may also be used as a signal that power is on, and in this role appear on computers, appliances, and on garage door openers. An LED is placed in some kind of LED holder in many cases in order to easily and securely inserts it into its working position.

When purchasing LEDs for a project, one will find that some LEDs come already attached to an LED holder, while some LED holders are offered for sale separately. LEDs already placed in an LED holder are often found in 4mm, 5 mm, and 6 mm (.157, .197, and .236 in), and colors such as orange, green, and red, as well as red/yellow. This type of LED holder should not be confused with an LED installation. They are small and inexpensive and often used as power indicators.

There is a much greater variety with the independently sold LED holder. First, there is a wide range of material. An LED holder may be made of thermoplastic, brass, painted plastic, chrome, or a combination of materials. Holders may be square or round, and they may screw into place or be of the snap-in variety. Holder colors are often black, white, chrome, or brass.

Things to Know About LED Lighting Cooler

Summary:
If you have not noticed that LED lights are cooler than other bulbs then, read this reader piece to get other amazing facts about the LED cooler and its other facts. 

Cooling Lightening

Upgrading the fluorescent lighting in the homes, offices and other places to LED cooler lights is a quick and affordable way to create luxury appeal. A simple LED cooler light is engineered as a replacement for the hot lamps for efficient fluorescent tubes with the convenience of brightness contrast and proper lighting. The single LED lights are the best replacement lamps that are second generation model that offers up to 80% power savings over the commonly used fluorescent bulb. This helps to lower heat emission which in turn substantially reduces the strain with the cooler compressors. 

These are the Facts!

Energy efficient lighting is in high demand, and several people are turning to LED bulbs for their efficient lighting needs. However, some people may have a disregard for such bulbs due to numerous reasons. So, before you kick the defective, high energy using hot light bulbs, here are a few things to know about when considering current LED cooler lights. 
Because LED cooler lights usually have low watt and voltage, the efficiency of LED lighting fixtures is superior. The cooler is the main reason for the LED light to run months longer than a standard fluorescent light. 
Yes! The LEDs are directional as they contain flat chips; the light of LED bulbs faces one way and tends to turn in every way. Some of the brands focus the light outward or creates a lens, so the light bends making the LEDs omnidirectional. 
LED lighting is highly-proficient and most eco-friendly lighting source present in the market. What’s more? It offers so many varieties to choose for different purposes. For years, people have only used one style of light bulb – the incandescent. Over a longer time, there was always a need for energy-efficient lighting, where CFL bulbs came onto the scene as a cheaper, and more energy-efficient lighting option. Then there became more advancement, so today, people have led lights available in the form of lamps, bulbs, strips and a lot more. 
Finally, there is no more waiting for longer minutes to get lights on, as the LEDs turn on instantly at full brightness. The brightness does not harm in any way, and the reason behind is that installation of LED coolers that consistently works to stabilize the LEDs in emitting the maximum light with warmness. 
The existing high powered LED microchips and the optics make sure the light is focused to where one needs the light to travel. The mainly designed optics allows an even dispersion of LED cooler light to the corners of the room. The LED cooler lights are designed to Left, Right, and Center fixture. 

In The End

The LED’s have created the best walk-in in the cooler range of bulbs in the current market. These lights make the best, most reliable lighting solution for every household and workplace.   

Inspired by LED Lights as Top lighting Trend of 2016

Summary:
The beginning of New Year 2016 is the perfect time to upgrade the interior decoration of your home. Luckily, you do not need to renovate your home completely only; you can update the lighting system to LED lighting that is in the trend. 

You need to know about it!

It is time to move on! The traditional incandescent bulbs are gone because of the introduction of innovative lightening known as is LED light. The manufacturers have shifted to LEDs because these operate on a more energy-efficient technology. Some people wonder why there is need to mandate while using them. The fact is that the LEDs are cheap, and they dim predictably, and also emit a warm and friendly glow. 

LED Lightening for Decorative Purpose

The broad range of LEDs offers to light decorative for office, homes, and commercial places. Since LED lighting is becoming standard in various fields, which compacts light in a greater way. These lights are long-lasting, attractive and consume much less power. Also, LEDs provide a very pleasant view of the people. LED lights can be used anywhere; be it a bathroom, study room or even living room. 

Focusing On the Advantages

Taking care of the environment of the homes and offices is a responsibility that everyone should feel for on a serious note. Most of us are already aware of current environment conditions that are not too friendly. However, many people are ignorant and cluelessness of new and upcoming technologies that are helpful in using to reduce carbon emissions. The best example of such innovation is LED lighting, which provides many environmental advantages that are discussed below: 
LEDs have a better quality of light distribution than others and focus light in one direction efficiently as compared to other types of lighting which emit light in all directions if not needed. This concludes that fewer LED lights are desired to achieve the same level of brightness as the fluorescent lamps. LED lights reduce energy consumption to a greater level.  
LED lights are up to 80% more efficient than the traditional lighting such as fluorescent. Maximum energy in LEDs is converted to the light and rest is wasted as heat that is relatively very lesser in numbers. Another best thing about the LED lights is that these also draw less power than the traditional lighting bulbs. 
Longer life span means lower carbon emissions. Yes! You guessed it right! The LED Lights last up to six times longer than other categories of lamps, which compel to reduce the frequent replacements of the lights in homes. 

Installing LED Lightening System

Whether you are installing a new LED lightening system in your office or home, you need to take care of a few things to make the right decision. One of which is to install an LED module. Using an LED module goes a long way in illuminating the area and cutting down the power cost at the same time. However, while picking the product, make sure you choose the one that supports the latest technology LED COB. A COB or Chip on Board is the most recent development in LED technology, which uses chips with multiple diodes for functioning. The technology enables a much denser LED array of light as against SMD technology. 

In The End

LED lights are cost efficient and can run utilizing less voltage. One must carefully look at the different watts and choose as per the requirement. 

Information on Cooling LED Lights and New Thermal Management Criteria

Summary:
Along with other electrical materials like bulbs and tube lights, now keeping LEDs cool in high-power LED designs is challenging in keeping them lit. This is how the LED thermal management is going on around.
 

An Overview

The majority of commercial lamps and other lighting mechanisms sold all over the world are LED-based. This vital step has helped countries in reducing their energy consumption as well as electricity bills. This is especially true with the some major factors where there are increased power densities, and lower thermal resistance packages being found in today's designs. This blog has come up to provide master basics of advanced thermal management and design. 

LED—It Is Getting Hot!

Despite the massive, decisive advantages of LEDs are there, but when compared to incandescent lights, they still waste around a greater percent of the electrical energy. This power appears to be heated and needs to be conducted away from the LED to maintain a safe operating temperature. Overheating of LED usually limits its lifespan and also impacts on the efficiency and quality as well.
For all these, there has been existing thermal management technologies that restrict the speed at which the LEDs penetrates to high powered and emits light. Huge working opportunities exist that can find cost-effective solutions for high-brightness LEDs to low-brightness one. 

LED Thermal Management—A New Approach

With the existing high-power LEDs, it is crucial to remove the heat from efficient thermal management. This will not be possible without a proper heat sinking, a junction where the temperature of LED rises. The high power designs have excellent points from where the thermal management solutions are done and assure a consistent system performance and long-term reliability. Presenting a tutorial on LED thermal management practices for lighting applications as— 
  • Improved circuit design to minimize heat spreading in the environment.
  • Understanding the LED's thermal performance as it relates to style, footprint geometry, and resistance all of which helps in making the most appropriate thermal solution in the LED lights.
  • Options are available for standard metal base circuit designs that can easily maximize thermal performance in a standard way.

Importance of Thermal Management

Effective thermal management is significant to ensure a consistent performance with long-term reliability of many LED light devices. With the vast array of presentations required for thermal management, the need for other thermal material solutions and original material placement methods continues to grow with the process. In this response, many companies have developed an array of highly efficient, flexible, and easy to grip thermally conductive materials to meet the latest and future needs for cooling electronic systems ensuring long term reliability. 

In The End

Hence, the designers and specifiers play a dynamic role in the progress of standard and core requirements to ensure quality lighting is maintained through efficient LED thermal solution.

Thermal management of high-power LEDs

15th, Jan. 2016 
Mingfa Tech Manufacturing Limited 
  
High power light-emitting diodes (LEDs) can use 350 milliwatts or more in a single LED. Most of the electricity in an LED becomes heat rather than light (about 70% heat and 30% light). If this heat is not removed, the LEDs run at high temperatures, which not only lowers their efficiency, but also makes the LED less reliable. Thus, thermal management of high power LEDs is a crucial area of research and development. It is necessary to limit the junction temperature to a value that will guarantee the desired LED lifetime. 
  
Heat sinks provide a path for heat from the LED source to outside medium. Heat sinks can dissipate power in three ways: conduction (heat transfer from one solid to another), convection (heat transfer from a solid to a moving fluid, for most LED applications the fluid will be air), or radiation (heat transfer from two bodies of different surface temperatures through Thermal radiation). 
  
Although a bigger surface area leads to better cooling performances, there is a need of space between the fins to generate a considerable temperature difference between the fin and the surrounding air. When the fins stand too close together, the air in between would become almost the same temperature as the fins, which makes thermal transmission will not be happened any more. So with more fins does not mean a better cooling performance. 
  
Mingfa Tech Manufacturing Limited is an LED thermal solution leading provider. Focusing on design and manufacture of high standard quality LED coolers including SimpoLED, EtraLED, GooLED, HibayLED, BuLED series, Mingfa Tech’s heat sinks were certified by Bridgelux, Xicato, Seol Semiconductor and LG Innotek, Lumileds and Luminus ......etc, which are compatible with more than 20 well-known LED COB brands. 
  
Thermal transfer takes place at the surface of the heat sink. Therefore, heat sinks should be designed to have a large surface area. This goal can be reached by using a large number of fine fins or by increasing the size of the heat sink itself. Mingfa Tech pin fin heatsinks is 10% higher in heat dissipation efficiency than normal heat sinks.

LED heat sink plays an important part in LED lighting

Mingfa Tech Manufacturing Limited

With the increase in heat dissipation from microelectronic devices and the reduction in overall form factors, thermal management bmomes a more and more important element of electronic product design. Both the performance reliability and life expectancy of electronic equipment are inversely related to the component temperature of the equipment. The relationship between the reliability y and the operating temperature of a typical silicon semiconductor device shows that a reduction in the temperature corresponds to an exponential increase in the reliability and life expectancy of the device. Therefore, long life and reliable performance of a component may be achieved by effectively controlling the device operating temperature within the limits set by the device design engineers. Heat sinks are devices that enhance heat dissipation from a hot surface, usually the case of a heat generating component, to a cooler ambient, usually air. For the following discussions, air is assumed to be the cooling fluid. In most situations, heat transfer across the interface bet when the solid surface and the coolant air is the lead efficient within the system, and the solid-air interface represents the greatest barrier for heat dissipation. A heat sink lowers this barrier mainly by increasing the surface area that is in direct contact with the coolant. This allows more heat to be dissipated and/or lowers the device operating temperature. The primary purpose of a heat sink is to maintain the device temperature below the maximum allowable temperature specified by the device manufacturer.

Mingfa Tech has been focusing on LED thermal solution since 2009, which was certified by many famous LED cob brands, such as Xicato, Bridgelux, Lumileds, Luminus, LG Innotek, Seoul Semiconductor, and so on. Mingfa Tech’s 5 series heatsinks (SimpoLED, EtraLED, GooLED, HibayLED, BuLED) are much welcomed in global market especially America and Europe. Mingfa Tech helps LED lighting OEMs substantially in their designs by improving the efficiency in heat dissipation and with more aesthetic looks.

LED Coolers are in great demand with the development of LED lighting market

LED is a highly energy efficient lighting technology, and has the potential to fundamentally change the future of lighting in the United States.  Residential LEDs -- especially ENERGY STAR rated products -- use at least 75% less energy, and last 25 times longer, than incandescent lighting. 
Widespread use of LED lighting has the greatest potential impact on energy savings in the United States. By 2027, widespread use of LEDs could save about 348 TWh (compared to no LED use) of electricity: This is the equivalent annual electrical output of 44 large electric power plants (1000 megawatts each), and a total savings of more than $30 billion at today's electricity prices. 
HOW LEDS ARE DIFFERENT
LED lighting is very different from other lighting sources such as incandescent bulbs and CFLs. Key differences include the following: 
·         Light Source: LEDs are the size of a fleck of pepper, and a mix of red, green, and blue LEDs is typically used to make white light. 
·         Direction: LEDs emit light in a specific direction, reducing the need for reflectors and diffusers that can trap light. This feature makes LEDs more efficient for many uses such as recessed downlights and task lighting. With other types of lighting, the light must be reflected to the desired direction and more than half of the light may never leave the fixture. 
·         Heat: LEDs emit very little heat. In comparison, incandescent bulbs release 90% of their energy as heat and CFLs release about 80% of their energy as heat. 
·           
Nowadays, the led lighting market is more bigger than before and the requirement is also large than before. The led lighting have been increasing diverse, and have many kinds of led lighting, what’s  more, Lighting accessories also have highly demands, such as led heat sink.
