Diagrams of GU10 LED Spotlights

In this post, they will discuss GU10 LED spotlights.

GU10 spotlights have been often used in spotlighting applications. Traditional GU10 spotlights are halogen lamps. Usually, under current light efficiency of LEDs, 3W LEDs is equivalent to 20W halogen lamps, and 5W or 6W LEDs is equivalent to 40W halogen lamps in terms of lux. Here the picture shows a 4*1W GU10 LED spotlights. See Fg. GU10 LED Spotlights.

From the appearance point of view,  GU10 LED spotlights and halogen spotlights look almost the same. However, in fact, the difference between them is very big.

Light Source:light source is the essential difference between LED spotlights and halogen lamps, and that is the reason why LED lights are much more efficient than halogen lamps. halogen lamps generate light by heating tungsten that covered by halogen gas, while for LEDs, basically describing, when current goes through LEDs, compounded particles in P-N junctions will then release photons (energy). LEDs generate less heat when emitting light, that is the reason why LEDs are much more efficient than halogen lamps and incandescent bulbs.

Materials: materials are different, LED spotlights usually need aluminum heatsink for  heat dissipation while halogen spotlights do not – their lamp bodies are usually made of plastic.

Driver: furthermore, LED spotlights need drivers (or transformers) in order to be running in existing GU10 fittings, normally 110V or 240V high-voltage fittings.

The picture below illustrates a typical GU10 LED spotlight exploded view. The spotlight is decomposed into 7 components as can be seen from the diagram. The following are the corresponding annotations.

   1. Lens: beam angle usually customizable

   2. Screws

   3. LEDs

   4. MC PCB

   5. Heatsink

   6. Plug holder

   7. Replacable plug: GU5.3,E26,E27,B22
