LED Par30 Lamps
Traditional Par lamps are commonly used in stage ligting applications. Par lamps are used to illuminate the stages, with dynamic-changing light colour, they are common lighting fixtures on the stage. However, because of the high power consumption, Par lamps are now gradually being replaced by LED PAR lamps. LED Par Lamps are designed to replace traditional halogen Par lamps. 5W LED to replace 40W halogon, 7W LED to replace 50W halogen, 9W LED to replace 60W halogen, 12W to replace 75W halogen, 80-90% energy saving. See Fg. LED Par30 Lamps.
From the appearance point of view, LED Par lamps and traditional halogen Par lamps look very similar. However, in fact, the difference between them is tremendous.
Light Source: light source is the essential difference between LED Par lamps and halogen Par 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.
LED Par30 Lamps - Dimension
Materials: materials are different, LED Par lamps usually need aluminum heatsink for heat dissipation while halogen Par lamps do not - their lamp bodies are usually made of plastic.
Driver: furthermore, LED par lamps 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 LED Par30 lamp's exploded view. The Par30 lamp is decomposed into 9 components as can be seen from the diagram. Following are the corresponding annotations.
