The spotlight is the use of concentrated lens or mirror to light.Reflected light spot light type is simpler, intensity of illumination is strong, according to the picture of narrow, facilitate the scene in the specific geographical focus light lamp, indoor studio and studio with at most a lamp.LED spot light adopts LED as light source.
The difference is led spot light and spot light, led spot light is the led lamp bead, rather than the traditional light bulb, the service life of led lamp bead long service life than traditional light bulbs, function is the same, are concentrated.
LEDs are produced by superconducting luminous crystal ultra high strength light, it emits less heat and, unlike incandescent light gives off a lot of heat, not because of high energy consumption and produce toxic gases like fluorescent lamp, also don't like neon lights for high voltage and easy to damage, has been all is recognized as a new generation of environmental protection high-tech products.
