Most properties of an LED depend on the temperature. Not only the luminous flux and therefore the efficiency but also the lifetime, wavelength and the chromaticity coordinates change with temperature. The higher the temperature, the more the properties are influenced negatively. In general, there are three physical mechanisms to transport heat: radiation, conduction and convection. The design of a heat sink (led cooler) has to consider these mechanisms to improve the thermal performance.
In comparison to traditional incandescent lamps the thermal power loss of the LED itself is not radiated and has to be dissipated by thermal conduction from the LED into the applied heat sink (led cooler). The design of the heat sink (led cooler) has to ensure that the heat is conducted through the material to the surfaces where it is transported to the environment by convection and radiation. Considering a given space available for a heat sink ( led cooler) and thus the same surface area of circumference, the special design of the heat sink ( led cooler) has a minor impact on the heat dissipation by radiation whereas the heat conduction and convection are effected by the material and the geometry of the heat sink ( led cooler). Thus, the design of a heat sink (led cooler) has to fulfil two aims: good thermal conduction in the heat sink (led cooler) and good thermal convection on its surfaces.

Factors Affecting LED Lightings

LED lights are the latest genre of lightings which are widely known for their energy efficiency and smart solution for illumination. With recent research and developments in the area of LED illumination, LED lights have now become part of the green revolution. With this, there have been a rise in LED related accessories like LED light bar brackets, LED flashing light sticks, LED coolers light and many more. From long-life to eco-friendly, there are a number of advantages of LED lightings. However, before opting for LED lights, one should be aware of various factors which affect the performance and durability of these lights. Let us know about these: 

LED power supply

Usually, the lifespan of LED bulbs vary up to 50,000 hours, means 10 years of usability. To maximize their luminous efficiency, they need a good power supply which is referred to as driver. For better performance, LED lights should be run in a power supply that has the facility of controlling voltage. Integrated lighting also affects LED power supply and its light effects. 

LED Heatsinks

Heatsinks remove the heat produced by the LED and enhance the efficiency of LED lights. There are several factors that affect the performance of this important device. 
·       Size – A higher surface area facilitates fast removal of heat. The surface area of a heat sink can be maximized by increasing either the size of overall heat sink or number of fins in the heat sink. 
·       Surface area – A heat sink with painted surface dissipates more amount of heat. 
·       Material – Material is a major factor that greatly affects the performance of the heat sink. There are several materials like copper, stainless steel, and aluminum which can be used to make heat sinks. However, thermoplastic materials are the latest development in the area of heat sink materials which are quite popular for not only being a good conductor of heat but also for their low production cost. 

Capacitor of LED drivers

The type of the capacitor used to store energy in LED bulbs affects the performance of LED lights. Usually, plastic capacitors are used in bulbs. When used regularly, capacitors run for around a year. However, heat and several other factors can affect the lifespan of capacitors. Now-a-day ceramic capacitors are being used for their higher tolerance and therefore getting popularity for their long-lasting property. 

Temperature

The luminous power of LED lights is greatly affected by temperature. The higher the temperature, the shorter is the life. Cooling case plays a major role here. Its temperature should always be maintained below 85°C so that it can function well. A dry, stable environment and optimum temperature increase the lifespan of LED bulbs. 
Conclusion – Now you know about all the factors which affect the performance and lifespan of LED lights. While opting for LED, keep these facts in mind and illuminate your house. 

Reasons For Using Pin Fin Heat Sink For LED Lighting

In the last few years, the electronic system has become more advanced in both designs as well as performance. While talking about semiconductor devices in this series, cooling of devices has become quite important and popular. It is where heat sinks act as a heat exchanger and helps to cool a device by dissipating heat to the surrounding medium. In the case of LED lights, older style heat sinks were found to be insufficient for cooling newer devices. And from here a new genre of heat sink arose i.e. pin fin heat sinks. 

What is pin fin heat sink?

Pin fin heat sink belongs to the new type of heat sink that increases the surface area of the device, thereby maximizing the contact area of the device to surroundings. Used in several devices, this technique works very well in LEDs. Among several types of heat sinks, pin fin heat sinks have gained much popularity. It is similar to a standard heat sink except it comprises of pins that are protracted from the base. These pins come in various shapes – square, cylindrical, elliptical, etc. 

Factors Effecting Performance of Heat Sinks

√  Size – by increasing the size of the heatsink or number of fins, the surface area of the heatsink can be maximized. As the transfer from the device to the surrounding takes place using heat sink, a larger area means readily transmission of heat. 
√    Finishing surface area – a high-bay LED heat sinks with painted surface is quite handy in fast dissipation of heat. 
√  Material – the performance of the heat sink is greatly decided by its material. Copper and aluminum are two preferred material of heat sinks as they have high thermal conductivity. In this category, high-bay LED heat sinks are quite popular as they are manufactured with aluminum and give the best lighting. 

Features and advantages

√   Low-pressure drop is the quality of heat dissolving in pin fin module which results in high efficiency of the device 
√   Pin fin heat sinks manufactured from aluminum minimize the thermal resistance from the base lights. 
√   Low weight LED lights 
√   Pin fin heat sinks come with sensitive thermal tapes 

Reason to use pin fin heat sinks

Pin fin heat sinks for LED devices are specially designed with an air pass which uses forced convection to dissipate the heat conveniently. When used in LED lighting devices, it produces bright lights. 
Pin fin heat sinks are known for their cooling capacity. So when used in lighting devices, it gives out adequate light devoid of any heating effect.
Conclusion – Now you must have understood the role of the heat sink in LED lighting devices. Next time, when you purchase LED lights, keep the quality of heat sinks in mind. Choose the best product and illuminate your house.

LED Lights—Materials That Impact The Performance Of Lighting

Summary: 
LED lights are today’s talk of every home and office for decorative purposes and functionality. This article tells that how LED lights are such valuable today and for what reasons it provides such eminent lighting. 

An Overview

As we all know that LED lights are today’s tremendous alternative to the traditional and conventional incandescent lights that are being widely used until the arrival of the LED lights. LEDs have longer lives than incandescent lights. In fact, some of the LED types last for 1, 00,000 hours as compared to the lesser life of incandescent bulbs. 

A Major Decision While Buying LED Lights

One of the biggest concerns while buying LED lights is its life. “For how long does LED light function properly?” is the major question which pops up by every buyer. High Bay heat sinks of LED lights play a significant role when concerning about life of the LED light. Heat sinks are usually placed at the back of the LED lights. So people might also think, “Why do they bother about what is at the back if the LEDs are working properly?” The fact is that the thing which is at the back—heat sink- is the most important aspect for the lifetime of an LED light. The heat sink or the material used directly affects the life of the LED light. So, while buying, people should check the material of the heat sink so, the lights perform the best. 
One must have seen water sinks in the bathroom. What do they do? They remove the additional water in the container thus helping to have a smooth and continuous flow of water in it. Similarly, a heat sink works in this manner. High bay heat sink acts as a sink to remove the heat from a system. Subsequently, in an LED light, when heat is produced, the heat sink removes the heat from it, thereby certifying removal of heat in a continuous way from the system and improving the performance of the LED light. 

Factors Depending on Performance of Heat Sinks

Since some heat sink types like LED Light bar brackets absorb heat from the LED light and dissipates all outside, here are a couple of factors on which the performance of a heat sink depends— 
Since the transfer of heat from the LED light to the surroundings take place from the heat sink, it is advised that the surface area of the heat sink should be large. The vast surface area of a heat sink can be achieved by increasing the number of fins, or by increasing the size of the heatsink altogether. 
A high bay heat sink with a painted surface improves the amount of dissipation of heat. This effect can even be more pronounced when the transfer of heat happens by radiation of heat in the surroundings. 
This covers one of the most important factors responsible for the performance of the heat sink. Copper has very high thermal conductivity while another choice for the material of the heat sink can be aluminum as well. The eminent heat sink types like High Bay Heat Sinks are manufactured with aluminum which provides the best lighting than anything else. 

Closing Lines

Thus, while buying the LED lights, every customer should consider the quality of heat sinks responsible for prominent LED lighting.

What Decides the Quality of LED Light?

Summary:
With an extended lifespan and far low running costs as compared to traditional bulbs, LED lighting has begun to spread more efficient light into the homes across the globe. But, what decides the quality of such eminent LED lights and what do you need to know before converting to LED? Let us know here in this blog.

A Start Off

LED—Light Emitting Diode has come up to be efficient and sustainable lighting source with countless applications. There are many types of light emitting diodes, and each diode is used for some particular purpose.
LEDs are extremely durable and are made up of sturdy components that withstand even the roughest condition. As having numerous advantages of LED like energy efficient, no ultraviolet rays emission, durable, flexible, ecologically friendly, and operational in every season, low voltage supply, reduced power consumption and more, these lights emits an enormous amount of light that dissipates equally.

Determining the Factors

Now that the LED lights are available in the global market, the question arises what are those important factors that decide the quality of the LED light? Today we will discuss the factors:

Chips

The chips take up 40% of the cost of an entire LED light. In authentic LED lights, it is the chip with decides the price of the LED Lights. The development of the LED Chips with technology leads the direction of LED Lighting. Hence, not only the brand of the chip decides the price, but also the quality as well.

LED Coolers—Heat Sinks

As we know that LED emits an enormous amount of light which dissipates equally so, it is imperative to keep the LED junction below the maximum operating temperature. Hence, this can be achieved by using high quality of LED heatsinks or commonly known as LED cooling property. LED heat sink is a device which is used just to absorb the heat and cool up the device by dissipating heat into the surrounding equally. Also, to extend the life of LED light bulbs, the manufacturers look forwardly to use LED cooling options.

LED Fixtures

The active cooling technology—LED coolers use convection to move heat off of the LED. As the air moves across fixtures, the heat is dissipated. By using an active fan, the amount of air passing over the LED fixtures becomes high enough to keep the fixture cooler. Thus, the LED fans and fixtures also play a significant role in making the LED lighting as a quality approved lighting across the globe.

Advantages of Converting to LED lighting

Efficient to Energy

LED lights are up to 90% more energy efficient than filament or halogen bulbs as the traditional lighting sources.

Long-Life

An accurately installed LED light lasts over 50,000 hours, as compared to the 5,000 hours of traditional bulbs.

Instant turn-on

The LED lights turn on instantly unlike other traditional lights which have a warming up period and lit up taking some minutes

Manageable

The LED lights can be controlled and managed for brightness and color as well as for setting it according to directions. This means the light is nowhere wasted.

Environmental friendly

The LED lights contain no mercury or other hazardous substances. Moreover, that is the reason they are greatly preferred for extended lighting time.

Closing Lines

Thus, the LED module of LED lights is manufactured and set up so well that the LEDs are capable of emitting eco-friendly lights without any hassle.
