Description
Technical field
The utility model relates to a kind of light fixture extending the LED life-span.
Background technology
LED lamp is assembled on same pcb board by a lot LED usually, in order to improve brightness and luminous efficiency, adopts the working method of high brightness big current, temperature is caused to raise, if can not the maximum temperature of control LED effectively, will directly have influence on the service life of LED, reduce luminous efficiency.
The mode of heat radiation, usually heat transfer is had, heat radiation and cross-ventilation etc., comparatively speaking, cross-ventilated cost is lower, but air is good heat-barrier material, poor by air radiating effect, for this reason, application number be 201010139375.8 Chinese patent disclose a kind of LED, described LED comprises LED chip, cooling base and lampshade, described lampshade is fixed on described cooling base, described LED chip is in described lampshade, described lampshade is filled with heat-conducting gas, this invention LED heat dispersion significantly promotes, can comparatively good berth at a lower temperature, but this complex structure cost is higher, also be inconvenient to safeguard.
Heat conducting effect is better, and common heat dissipating method increases fin etc., and its Problems existing is that cost is higher, structure is more complicated, and volume is larger.
Also have and fin and fan combination used, be usually used on the light fixture of super high power.
Utility model content
The utility model, according to above not enough, provides a kind of light fixture extending the LED life-span, and the method combined of mainly the heat scioptics heat loss through conduction of LED, air dispel the heat improves radiating effect, thus reduces the temperature of LED, the life-span of prolongation LED.
The technical solution of the utility model is:
A kind of light fixture extending the LED life-span, comprise: lamp holder, the lampshade be connected with lamp holder, lampshade is provided with lens, in lampshade, pcb board is installed, pcb board is welded with electrical equipment control assembly and some LED, electrical equipment control assembly connects LED and lamp holder respectively, both are respectively arranged on two faces of pcb board, and the inner face that LED illuminator is close to lens is installed, LED illuminator scioptics heat loss through conduction.
As preferably, the inner face of described lens has plane, and the end face of LED illuminator is also plane.
In order to improve heat-conducting effect, between the end face of described LED illuminator and the inner face of lens, scribble transparent heat-conducting silicone grease.
Some LED setting height(from bottom)s want consistent, as long as illuminator to be close to during installation pcb board welding, substantially can to meet instructions for use, have making up by heat-conducting silicone grease of alignment error.
As preferably, described lens are made up of glass.Though glass is hot good not as good as metal guide, heat conductivility is much better than air, and in fact heat-conducting plastic lens also can be selected.
A step is provided with in described lampshade, described pcb board is arranged on the below of this step, described lens are arranged on the below of described LED illuminator, lens protrude relative to the port of lampshade, also comprise lens crown cap, hollow out in the middle of this lens crown cap, lens are fixed on lampshade by it, and this technical scheme can guarantee that LED illuminator is close to the inner face of lens.
In order to improve insulating properties and heat dispersion, described lampshade is insulating boot, and insulating boot outward part is coated with metal cap, and lens are fixed on metal cap by described lens crown cap.
The position that described lampshade is covered by metal cap offers through hole.The heat produced in lampshade can also pass through cross-ventilation, and via through holes is dispelled the heat by metal cap.
Lens are gone back scioptics crown cap and are conducted heat in metal cap, dispelled the heat by metal cap while dispelling the heat to air.
The utility model has the beneficial effect that structure is simple, cost is low, reduce LED temperature, extend the LED life-span.
