The raising of the power of LED, and it is integrated use, it is more prominent that heat is shed, light efficiency is improved and chip cooling goes wrong, same with this
When, reduces cost turns into the problem that need to be solved.It is heat when LED lights with 80% power to influence one of problem of LED power
Can distribute, the effect of the bad light decay for directly affecting LED that such as radiates, temperature often raises 1 degree, light decay about 1%, meanwhile, it is too high
Temperature directly affect life-span of LED chip, therefore, it is LED encapsulation structure to improve heat dispersion, improve light efficiency, reduces cost
On the problem that need to solve.
Existing light source and radiator structure are：
1st, by making circuit on ceramic substrate, the then fixed chip on ceramic circuit-board, by gold thread or scolding tin
Light source is formed after connection, light source is fully contacted by heat-conducting glue with cooling base, by heat derives to radiating element, so that real
The radiating of existing light fixture.
2nd, light source is welded on ceramics or metal substrate by way of welding, then is being dissipated baseplate-laminating with heat-conducting glue
On thermal device.
The gap between heat-conducting glue filling light source bottom surface and radiating element is needed between above-mentioned light source and radiating element, and
Current heat-conducting glue thermal conductivity factor, so as to form thermal resistance at heat-conducting glue, influences the derivation of heat far below the thermal conductivity factor of ceramics；
Other light source is fixed on radiating element, because radiating element is generally hardware, therefore when high pressure is connected, is easily occurred
Light source punctures with heat dissipation metal device, causes to occur short circuit and causes that light fixture is damaged or personnel injure.
