Description
Technical field
The utility model relates to a kind of LED lamp of LED lamp, particularly a kind of high light efficiency, belongs to LED technical field of lighting fixtures.
Background technology
The factors such as LED light efficiency is mainly limited by the photoelectric transformation efficiency of LED at present, and LED encapsulates light loss, and the heat radiation of LED lamp is bad.Front loss depends primarily on the level of selecting of current LED manufacturing process and material, As time goes on, improves with annual more than 20% speed.The bad problem and LED lamp dispels the heat hampers the raising of light efficiency always, is the maximum bottleneck of LED industry.
The main method of LED lamp heat radiation is at present that LED is attached on PCB or metal substrate, then PCB or metal substrate are attached in metal heat sink.And metal heat sink must have enough large area to contact with air, just can reach the effect of heat radiation.And certainly will reduce like this light-emitting area of LED lamp, cause LED lamp profile heaviness, the drawback such as light-emitting area is little, and lighting angle is limited, cost increase.
Summary of the invention
The utility model is for the problems referred to above, based on the outer radiating surface that reduces metal heat sink, utilizes LED lamp light-emitting area to reach heat radiation.
Thinking of the present utility model is as follows: LED light-emitting area is all to make lamp housing by glass or printing opacity plastic cement at present, with the air across certain distance between LED, and be enclosed in lamp and do not flow, and air thermal conductivity factor is very low, therefore LED work is that the heat energy producing is difficult to dispel the heat away by light-emitting area.Helium higher thermal conductivity factor or other gas are replaced air by the present invention, is enclosed in LED lamp, the heat energy of LED chip passed on printing opacity lamp housing by the higher helium of thermal conductivity factor or other gas, then be diffused in air by lamp housing.
Specifically, high light efficiency LED lamp described in the utility model, comprise lamp holder, lamp body and lampshade, lamp body comprises mounting base, and mounting base surface is provided with plurality of LEDs, and mounting base is heat conduction cylinder, LED is attached at the top outer surface of heat conduction cylinder, mounting base surface is coated with the heat-radiation coating bed of material, and lampshade, on lamp body, is filled with the gas that thermal conductivity factor is high in lampshade.
Further, the gas that described thermal conductivity factor is high comprises hydrogen, helium, neon, or its two or three's mist, and hydrogen, helium, neon with other gases in the mist of different ratios.
The thermal conductivity factor of several gases is as follows: 1, hydrogen: 0.163; 2, helium: 0.144; 3, methane: 0.0300; 7, neon: 0.0455; All higher than the thermal conductivity factor 0.0233 of air.
Further, described heat conduction cylinder is made up of metal or other Heat Conduction Material, and shape comprises cylinder, cone or multiple edge body.
Further, described lampshade is glass shell or other light transmissive material shells.
Further, described lamp holder is screw socket or bayonet socket.
High light efficiency LED lamp described in the utility model, by fill the gas of high thermal conductivity coefficient in lampshade, and apply the heat-radiation coating bed of material on mounting base surface, heat dispersion increases substantially, and need not reduce the light-emitting area of LED lamp, do not increase the weight of LED lamp, solved the problem of thermal diffusivity and LED lamp weight.
Brief description of the drawings
Fig. 1 is the schematic diagram of the utility model embodiment;
Wherein, 1 is that lamp holder, 2 is that mounting base, 3 is that LED, 4 is that the gas, 5 that thermal conductivity factor is high is lampshade.
