Due to the adoption of the arc-shaped honeycomb through hole structure, the heat-dissipating LED lamp is better in heat dissipating effect; because heat conducting materials are filled into space between the LED light source and the heat transfer plate, heat transmitting effect is improved; because battery boxes integrally arranged are not provided, the heat-dissipating LED lamp can adapt with different conditions; the heat-dissipating LED lamp saves cost and is light in overall structure, and used materials are reduced.
Description
Technical field
The utility model relates to a kind of illuminating LED lamp, particularly a kind of heat radiating LED lamp.
Background technology
The LED lamp is compared with conventional incandescent, has energy consumption is low, the life-span is long, applicability is good, and is the not mercurous poisonous metal of Denging, and the advantages such as environmental protection are widely used at present.
LED chip is directly related with temperature service life, and the heat dissipation problem of LED chip is restricting the development of LED lamp always, and the radiator structure that light fixture is good can reduce the LED chip temperature in when work, reduces the light decay of LED chip and extends service life of LED chip.Original LED light fixture adopts die casting aluminium heat-conducting plate and fin slices radiator to combine more, and this radiator structure has increased area of dissipation, but can't dispel the heat by the free convection of air, and radiating effect is general.Most light fixtures adopt the in-built electrical source capsule, in order to place the LED driving power, still, when some does not need the LED built-in power, will cause the waste of light fixture material, and the cost of light fixture is increased.
The utility model content
According to above deficiency of the prior art, the technical problems to be solved in the utility model is: a kind of heat radiating LED lamp is provided, and good heat dissipation effect improves light efficiency and service life.
Heat radiating LED lamp described in the utility model, comprise LED light source, lens, lamp housing, lamp housing is cellular through-hole structure, cellular through hole be shaped as regular hexagon, heat-conducting plate is set in lamp housing, heat-conducting plate bottom fixed L ED light source, the LED light source front arranges lens, lens arranged outside lens trim ring, the lens trim ring is fixed on heat-conducting plate, between lens outer rim and lens trim ring, sealing ring is installed, the wire of LED light source is connected with lamp socket, lamp socket is connected with lamp housing, and lamp housing is provided with trough, fixing upper end cover on trough.
The heat-conducting plate upper surface has the yi word pattern wire casing, and the wire of LED light source passes the through hole of heat-conducting plate, enters in the yi word pattern wire casing, then passes through trough on lamp housing, be connected with lamp socket, on trough fixedly upper end cover can play dustproof effect.Heat-conducting plate can be integrated also and can be fixedly connected with lamp housing.The utility model does not have the in-built electrical source capsule, has saved cost, when needs are used power pack, and can the external power supply box.Overall structure uses material few, has alleviated the weight of light fixture, reduces costs.
Adopt cellular through-hole structure can better realize the rapid flow of cold and hot air, radiating effect is obvious, and arcuate structure not only can increase area of dissipation, and has increased the cross-ventilation heat radiation of the multiple directions such as crosswind, better heat-radiation effect.
Fill thermal conductive material layer such as the heat-conducting mediums such as heat-conducting silicone grease layer, heat conduction glue-line between described LED light source and heat-conducting plate, make both applyings better closely, promote LED light source to the heat transmission of heat-conducting plate.
The heat that LED light source work produces is delivered on heat-conducting plate by heat-conducting silicone grease, and heat-conducting plate passes to connected shell again, and arc shell is realized the multi-direction convection current of air by cellular through-hole structure, and heat flows away from shell with the convection current of air, realizes heat radiation.
The beneficial effect that the utility model compared with prior art has is:
This heat radiating LED lamp adopts the cellular through-hole structure of arc, and better heat-radiation effect is filled Heat Conduction Material between LED light source and heat-conducting plate, promotes heat-transfer effect, without the in-built electrical source capsule, can adapt to different situations, save cost, overall structure is slim and graceful, reduces the use of material, reduces costs.
