Description

A kind of high-power LED light source

Technical field

The utility model relates to electric light source, particularly is a kind of LED lamp.

Background technology

Semiconductor light-emitting-diode LED is a kind of new type electro source, and its basic functional principle is to utilize the solid semiconductor chip as luminescent material.When the LED two ends add voltage, the son that dams in the semiconductor takes place compoundly to cause photo emissions and produce light, the only non-radiative light that is gone out, photochromic pure, light beam concentrated, high, the good temp characteristic of colour rendering index.It has advantages such as electric quantity consumption is low, stable performance, the life-span is long, pollution-free, use is simple.Be used for illumination and decoration at present in a large number, several ten thousand LED lamps, a hundreds of thousands point just be installed as Beijing Olympic venue the Water Cube, can up to ten million kinds of colors of conversion.But the existing single power of LED is very little, poor reliability, because global design is unreasonable, lifetime of system is short, can not satisfy the requirement of large power long life-span illumination.

Summary of the invention

Purpose of the present invention is exactly that a kind of high power semi-conductor led light source that is used to throw light on will be provided.It is operated in 48 volts of above high-voltage alternatings or dc source, by LED illuminator module, lamp holder, the led light source drive circuit, insulator, metal heat sink is formed, LED illuminator module is made up of one or plurality of LEDs serial or parallel connection, these LED are welded on and form LED illuminator module on the good circuit board of thermal conductivity, led light source drive circuit available wire one end connects the LED illuminator module other end and connects lamp holder, the lamp holder that insulator will contact high voltage part insulate with other parts and it is reliably linked together, and lampshade or printing opacity colloid profile can be the tubular or incandescent lamp bulb shapes of fluorescent lamp; Can be garden shape or ellipse; Can also be three-side cone or polyhedron shape, waiting the three-dimensional structure bodily form also can be planar shaped.Can there be Transparent lamp shade or printing opacity colloid to prevent dust or waterproof in the outside of LED illuminator module.Change high-power LED light source by the output of controlling the led light source drive circuit and send different colours or make its power output with former power 1/2nd or 1/3rd, the outer surface around metal heat sink 5 can have the radiating fin or the fin of convex-concave.Can satisfy the room lighting needs of heavy constructions such as auditorium, stadiums.Its power is also adjustable, and heat dispersion is also fine.The lamp housing pattern can be varied.
