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 is according to above not enough, provide a kind of LED lamp based on lens heat loss through conduction, the method combined of mainly the heat scioptics heat loss through conduction of LED, air being dispelled the heat improves radiating effect, thus reduces the temperature of LED, extends the life-span of LED.
The technical solution of the utility model is:
A kind of LED lamp based on lens heat loss through conduction, comprise: lamp holder, lampshade, 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 is electrically connected LED and lamp holder respectively, the inner face that LED illuminator is close to lens is installed, and also comprise the elastic parts be arranged in lampshade, this elastic parts applies elastic force in the middle part of pcb board, the LED in the middle part of pcb board is made to be close to the inner face of lens, LED illuminator scioptics heat loss through conduction.
Pcb board and the modal fixing point of lampshade are the peripheral positions of pcb board, when pcb board area is larger, if do not apply elastic force in the middle part of pcb board, along with the passing of service time, in the situation such as high temperature, gravity, can deformation be there is in pcb board, due to light fixture use time, the direction of illumination is uncertain, may face upward or downward, also may towards a left side or towards the right side, therefore, likely cause the LED at middle part to depart from lens, do not reach the effect of heat loss through conduction, in the middle part of pcb board, apply elastic force is exactly to solve this technical problem.
Further, 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 described elastic parts is arranged on the top of this step.
Further, described elastic parts comprises stock, and respectively there is a bent angle at the two ends of this stock, described pcb board is provided with two breach, and bent angle is positioned at breach and by described step card jail, also comprises an elastic component, the middle part of this elastic component one end and stock is fixed, and other end top is in the middle part of pcb board.
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.
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 described 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.
