Description

A kind of disjunctor LED lamp bead

Technical field

The utility model relates to lamp bead, specifically a kind of disjunctor LED lamp bead.

Background technique

With the development of science and technology, as low energy consumption, the representative of high brightness to gradually replace conventional electroluminescent lamp integument wide for LED light source General use.

In general, whether LED light work is stable, and quality quality radiates most important with lamp body itself, height in the market The heat dissipation of brightness LED light usually uses natural heat dissipation, and the effect is unsatisfactory.The LED lamp that LED light source is made, by LED, heat dissipation Structure, driver, lens composition, therefore radiate be also a part and parcel, luminous efficiency with environment temperature raising And decline, so the heat dissipation of LED is extremely important；Power supply it is high-efficient, its dissipation power is small, in lamps and lanterns internal heat generation amount with regard to small, Also the temperature rise for just reducing lamps and lanterns, can delay the light decay of LED；If LED cannot radiate very well, its service life also can be by shadow It rings.

The heat dissipating method of LED is mainly accounted for from the structure and material of lamp holder, generally using aluminium radiating fin as outer A part of shell increases heat dissipation area；Heat-conducting plastic shell makes radiator using LED insulating radiation plastics substitution aluminium alloy； Surface emissivity radiating treatment smears heat loss through radiation paint, heat is taken away lamp housing surface with radiation mode；Air hydrodynamics, benefit With lamp housing shape, convected air is produced；Fan reinforces heat dissipation with long-service life high-efficiency fan inside lamp housing；Heat conducting pipe, by heat Shell radiating fin is transmitted to by LED chip；The higher transparency liquid of thermal conductivity is filled into lamp body ball bubble by liquid ball bubble； Using lamp cap, there is the lamp cap of larger metal surface to radiate as screw socket；These methods are each has something to recommend him, can solve one A little problems, but have limitation, for compact LED lamp bead, it is unpractical for increasing additional heat dissipation equipment.
