LED Lighting

LEDs provide a better and safer light source by using a semiconductor to convert electricity into light.

Over the past 50 years LEDs have been used in every application imaginable, from car headlights to lighting our homes.

Benefit from increased energy efficiency, a cost-effective and longer bulb life solution for companies.

LED (light-emitting diode) lighting is a reliable, energy efficient and cost effective alternative to the conventional incandescent lights considered the preferable lighting choice until recently.  LED Lights can last up to 100,000 hours (over 11 years) compared to a very small life of an incandescent bulb. They are much more energy efficient as their consumption of electricity is lesser than the incandescent bulbs.

 

Today LEDs are most commonly used in applications such as: televisions, smart phones, tablets, traffic lights, car headlights and outdoor lighting.

Aluminium Heatsinks are an important cooling solution for most of today’s electronics. Heatsinks are becoming an increasingly popular thermal management solution for LED lighting because too much heat can damage LED phosphor which would result in lower light output, a change in colour and a significant decrease to its life expectancy.

 

The most common problem that we see in LED lighting applications stem from too small of a heatsink or sometimes none at all. At GD Rectifiers, we work with LED Lighting manufacturers to offer a wide variety of LED Heatsinks which include black anodised extruded aluminium heatsinks, clear anodised extruded aluminium heatsinks and forced air cooled aluminium heatsinks.

 

How Does It Work?

Aluminium Heatsinks used with LEDs are designed to absorb and disperse heat away from the LED light and in to the heatsink. Either passive or active air then circulates around the heat sink to help cool it.

Heatsinks absorb heat from the LED light and dissipates it outside, there are a several factors that affect the performance of the heatsink.

 

Factors Affecting LED Heatsink Performance

  • Heatsink Size – the surface area of the heatsink needs to be large, a higher surface area can be achieved by increasing the number of fins in the heatsink or by increasing the overall size of the heatsink too
  • Surface of the Heatsink – if a Heatsink is anodised, the dissipation of the heat is improved. The Heatsink effect is even more prominent when the transfer of heat is done by radiation of heat to the outside
  • Orientation – the orientation of the light source on the LED Heatsink has an effect on the overall Heatsink
  • Material – Copper, stainless steel and aluminium are all popular heatsink materials. Aluminium has a decent heat conduction capacity (which is better than stainless steel but less than Copper) and is the most cost effective material used for Heatsinks. Aluminium is the most commonly used material for LED Heatsinks because it is a good conductor, it is the preferred material and is used in most luminaries in the industry.

 

Reasons Why You Should Use LED Lighting

  1. LED lights will save you electricity because they require less energy to power
  2. They will save you approximately 80% of electrical power compared to incandescent bulbs
  3. LED lights do not contain hazardous solids, liquids or gases
  4. LED lights are a popular choice as automobile lighting because they have been proven to help reduce the risk of car accidents in daylight hours by 15%
  5. They are becoming increasingly popular amongst consumers, opting to invest in LED lights and choose from a number of different colours to define their style and desired ambience
  6. LED Lights use direct light which means there is no light pollution
  7. LED lights contain no UV light, eliminating the possibility of skin damage
  8. They provide local lighting solutions and improve visibility on the roads
  9. These lights do not require excessive maintenance once they’re installed
  10. LED lights last 2400% longer than regular halogen bulbs and can last up to 50,000 hours
  11. One major benefit of LED lights is that they immediately switch on without requiring a warm-up time
  12. LED lights are extremely reliable and are fully operational in all weather conditions
  13. LED lights are lightweight and recyclable
  14. They are much brighter than traditional lighting solutions, offering improved visibility and performance
  15. Another major benefit is because LED lights are environmentally friendly, they lower your carbon footprint
  16. LED lights do not emit radio frequency interference
  17. LED lights save consumers a lot of money on their electricity bills
  18. They can be used inside and outside your home
  19. LEDs are much cooler than incandescent lights which reduces the risk of combustion
  20. LED lights are made with epoxy lenses instead of glass which makes them much more resistant to breakage
