Abstract
The utility model discloses a heat-dissipation ceramic lamp cap and relates to an LED lamp cap. Though LEDs can save energy, like incandescent light bulbs, in the process that a part of energy is converted to light, the other part of energy is converted to heat, if the generated heat can not be timely dissipated, the surrounding temperature will increase, aging of chips and packaging resin is accelerated, welding spots can also be melted, the chips are made to lose efficacy, and the service life and the light emitting performance of the LEDs are directly influenced. The heat-dissipation ceramic lamp cap comprises a base and a connecting cover, wherein the inner wall of the connecting cover is connected with the outer wall of the base through heat dissipation ribs, and at least one ventilation groove is formed in the side wall of the connecting cover. The heat dissipation ribs are arranged on the lamp cap to increase the heat dissipation area, the ventilation groove increases the heat conduction effect, and therefore the temperature of a lamp is lowered, the service life of the lamp is prolonged, and the light emitting performance is stabilized.
Description
[technical field]
The utility model relates to a kind of lamp holder, especially a kind of LED lamp holder.
[background technology]
The at present application of LED is more and more extensive, and LED has its significant advantage, and for example: volume is little; Can reach 60,000 to 100,000 hours service life, longer more than 10 times than the conventional light source life-span; Conversion ratio up to 90% becomes luminous energy with electric energy conversion; Than incandescent lamp heat radiation still less.
Although LED is energy-conservation, but the same with general incandescent lamp, part energy is converted in the process of light in addition that part energy changes into heat, and especially LED is the point-like illuminating source, and its heat that produces also concentrates on minimum zone, if the heat that produces can't in time distribute, environment temperature will raise, and wearing out of speed-up chip and potting resin also may cause solder joint to melt, make chip failure, and then directly affect service life and the luminous performance of LED; Especially great power LED, its caloric value is larger, requires higher to heat dissipation technology.
In order to solve the existing above-mentioned heat dissipation problem of lamp holder, prior art disclosed following scheme:
Publication number discloses a kind of Novel LED heat dissipation lamp head in the patent documentation of " CN202469596U ", comprise lamp holder, lamp housing, LED lamp plate, driving power, wherein LED lamp plate and driving power are installed in the lamp housing housing, it is characterized in that arranging at the lamp housing waist location arcuate socket of equally distributed perforation, the gas port of equally distributed perforation is set at the lamp housing bottom position, outside LED lamp plate light-emitting area, is arranged with protective cover.Long arc-shaped holes on the housing matches with gas port, during its work and effectively ventilative heat radiation of cross-ventilation, guarantees the service life of LED light fixture.This lamp holder has strengthened heat dispersion, but destroys the sealing property of lamp holder, when the air in outside air and the lamp holder carries out convection current, has lost damp proof, humidity resistance.
Therefore, how effectively strengthening the heat dispersion of lamp holder, is the present technical issues that need to address of those skilled in the art.
[summary of the invention]
