China May Come out the Restrictions to Phase out Incandescent Light Bulbs

After the EU, the US, Australia and others have imposed restrictions to phase out incandescent light bulbs, it's reported that China is in the process of making the road map for banning the use of these bulbs. The restriction is expected to be unveiled in March.

According to Wang Jinsui, director general of China Illuminating Engineering Society, said in China Business News," The National Development and Reform Commission has been drafting the map."

Wang said the initial plan is to stop producing 100-watt incandescent bulbs after 2015 and ban them completely from 2018. China has provided subsidies for using energy-saving light bulbs since 2008, prompting many incandescent bulb producers to cut their output.

Diagrams of Typical LED Spotlights: GU10

Continuing with our last post” Diagrams of Typical LED Light Bulbs: E26,E27” regarding globe E27 LED light bulbs, in this post, we will talk about GU10 LED spotlights.

 GU10 LED Spotlights

GU10 spotlights have been commonly used in spotlighting applications. Traditional GU10 spotlights are halogen lamps. Typically, 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 very similar. However, in fact, the difference between them is tremendous.

GU10 LED Spotlights Dimension

Light Source: light source is the essential difference between LED spotlights and halogen lamps, and that’s 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, simply 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’s 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.

GU10 LED Spotlights Components

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
