Description
Technical field
The present invention relates to a kind of LED lamp utilizing face shield to dispel the heat.
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.
Summary of the invention
The present invention, according to above deficiency, provides a kind of LED lamp utilizing face shield to dispel the heat, and the method combined of mainly the heat scioptics heat loss through conduction of LED, air being dispelled the heat improves radiating effect.
Technical scheme of the present invention is:
A kind of LED lamp utilizing face shield to dispel the heat, comprise: lamp holder, lampshade, lampshade is provided with lens, in lampshade, pcb board is installed, pin pcb board being welded with electrical equipment control assembly and some LED, LED has a bending segment, when lens press the illuminator of LED, the spring energy that bending segment produces makes the illuminator of LED be close to lens inner face, the illuminator scioptics heat loss through conduction of LED.
We know, common LED is in welding process, have height, also our invisible injustice may be there is in lens, all LED are allowed to be all inconvenient with lens close contact, but, if when Elastic Contact all appears in each LED, just greatly can reduce both processing requests, the LED of direct erecting and welding can not have elasticity, but after bending process, when bending segment is longer, LED has certain elasticity, controls machining accuracy well, can ensure that the illuminator of each LED is close to lens inner face, the illuminator scioptics heat loss through conduction of LED.
The adaptable lens of the present invention comprise toroidal lens.
As preferably, described lens are planar lens, and correspondingly, the top of the illuminator of LED is plane, and the contact area of the program is comparatively large, and radiating effect is better.
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 also can use.
The bending segment of described LED pipe pin and pcb board are an angle.There is this angle, by multiple LED arranged in dislocation, not easily with adjacent LED short circuit, can improve LED packing density.
As preferably, described angle is 5-15 degree.
Described lampshade outward part is coated with metal cap, also comprises lens crown cap, and hollow out in the middle of this lens crown cap, be convenient to LED printing opacity, lens are fixed on metal cap by it.
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 position that described lampshade is covered by metal cap offers through hole.The heat produced in lampshade can also pass through cross-ventilation, is dispelled the heat by metal cap.
In order to improve insulating properties, described lampshade is insulating boot.
The present invention has that structure is simple, cost is low, the good beneficial effect of radiating effect.
