Abstract
The invention provides a high-light effect LED (light emitting diode) lamp, comprising a lamp holder, a lamp body and a lampshade; the lamp body comprises a mounting base; multiple LEDs are arranged on the surface of the mounting base; the lampshade covers the lamp body and is internally filled with gases with high heat conductivity coefficients; the gases with the high heat conductivity coefficients comprise H2, He, Ne or the mixed gas of two or three from the H2, He, Ne as well as the mixed gas of the H2, He and the Ne with other gases according to different proportions; the mounting base is a heat conductivity post body; the LEDs are attached onto the surface of the top end of the heat conductivity post body made of metal or other heat conductivity materials; the heat conductivity post body can be cylindrical, conical or polygonal prismatic. A radiating coating layer is coated at the surface of the mounting base. According to the high-light effect LED lamp, the radiating performance is greatly improved by filling the gases with the high heat conductivity coefficients into the lampshade and coating the radiating coating layer on the surface of the mounting base.
Description
Technical field
The present patent application 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, with annual more than 20% speed, improves.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 heavy, the drawback such as light-emitting area is little, and lighting angle is limited, cost increase.
Summary of the invention
The present patent application is for the problems referred to above, and the outer radiating surface based on reducing metal heat sink, utilizes LED lamp light-emitting area to reach heat radiation.
The thinking of the present patent application is as follows: LED light-emitting area is all to make lamp housing by glass or printing opacity plastic cement at present, with between LED across the air of certain distance, and be enclosed in lamp not mobile, and air thermal conductivity factor is very low, so LED chip work is that the heat energy producing is difficult to dispel the heat away by light-emitting area.The present invention replaces air by higher helium or other gas of thermal conductivity factor, is enclosed in LED lamp, the heat energy of LED is 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, the high light efficiency LED lamp described in the present patent application, comprises lamp holder, lamp body and lampshade, and lamp body comprises mounting base, and mounting base surface is provided with plurality of LEDs, 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, 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 mounting base is heat conduction cylinder, and heat conduction cylinder is made by metal or other Heat Conduction Materials, and shape comprises cylinder, cone or multiple edge body, and LED is attached at the top outer surface of heat conduction cylinder.
Further, described mounting base surface is coated with the heat-radiation coating bed of material.
Further, the light transmitting shell of described lampshade transparent glass shell or other materials.
Further, described lamp holder is screw socket or bayonet socket.
High light efficiency LED lamp described in the present patent application, 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.
