Abstract
The utility model relates to the technical field of LED lamps, in particular to a heat radiation device for an LED lamp. The heat radiation device comprises a plurality of LED lamps, a circuit board, and a bonding pad, and also comprises heat conducting insulation layers and metal layers, wherein the heat conducting insulation layers are covered on the upper and lower surfaces of the circuit board and the metal layers are covered on the upper and lower surfaces of the heat conducting insulation layers. By adopting the structure of double-surfaced circuit board, double heat conducting insulation layers and double metal layers, the heat of the LED can be radiated from both sides of the circuit board, which facilitating heat radiation. The utility model has the advantages of simple structure and good heat radiation effect, and can effectively prolong the service life of the LED lamp.
Description
Technical field
The utility model relates to LED lamp technical field, refers in particular to a kind of LED heat sink for lamp.
Background technology
On outdoor, road, public place and other places, people were to use osram lamp or the illumination of mercury bulb in the past.Osram lamp and mercury bulb are by high-power generation irradiation light, and still, the shortcoming of their maximums is the energy consumption height, not only can cause high heat history, also cause electrical damage, short circuit simultaneously easily.And for the illumination of outdoor and road except that needs satisfy the requirement of brightness, more should satisfy the requirement of energy savings, significantly raising along with social demand for energy, the lighting that the tradition power consumption is high is owing to cause a large amount of energy consumes, obviously do not met energy-conservation requirement, in order to solve the problems referred to above that the traditional lighting light fixture runs into, people's utility model the LED lamp, the LED light fixture has characteristics such as the high and low heating of luminous efficiency, power saving and life-span product, so they are in the current epoch of advocating environmental protection and energy saving and be employed more and more widely.Though the technology of LED lamp is increasingly mature, but various LED light fixtures in the market, still exist following shortcoming: single led luminous quantity is more limited, being used for normal lighting then will be with the integrated use of a plurality of LED, and still, LED is very high to the temperature requirement of environment, the LED lantern festival that high integration is used causes heat to accumulate in a large number in the less space, but also can not distribute preferably, thereby cause the decay of LED illumination and rapid wearing out, the service life of having reduced the LED lamp.LED light fixture on the market is that LED is integrated on traditional single face wiring board now, can only lean on the heat radiation of LED pin, so its radiating efficiency is very low, has limited the scope of application of high illuminance LED lamp.The measure that LED is dispelled the heat taked is also arranged at present, but the radiating effect effect does not reach desirable effect.
The utility model content
Technical problem to be solved in the utility model is, overcomes the deficiencies in the prior art, good heat dissipation effect is provided, can effectively improves the heat abstractor of LED LED in service life lamp.
The technical scheme that the utility model adopted is: the LED heat sink for lamp, comprise several LED, wiring board, pad, it also comprises heat conductive insulating layer, metal level, and described heat conductive insulating layer is covered in the upper and lower surface of wiring board, and described metal level covers sub-heat conductive insulating layer upper and lower surface.
Curved shape of described metal level outer surface or teeth shape below the described wiring board.
Described metal level is adopted and is made of aluminum or copper.
The beneficial effects of the utility model are: the utility model comprises several LED, wiring board, pad, it also comprises heat conductive insulating layer, metal level, described heat conductive insulating layer is covered in the upper and lower surface of wiring board, described metal level covers sub-heat conductive insulating layer upper and lower surface, owing to adopt this double-sided wiring board to add the structure of two heat conductive insulating layers, double-metal layer, the heat of LED is distributed from two surfaces up and down of described wiring board, more help heat radiation, simple in structure, the good heat dissipation effect of the utility model, the service life that can improve the LED lamp effectively.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, by embodiment the utility model is described in further detail,
As shown in Figure 1, the LED heat sink for lamp, comprise several LED1, wiring board 2, pad 3, it also comprises heat conductive insulating layer 4, metal level 5, described heat conductive insulating layer 4 is covered in the upper and lower surface of wiring board 2, curved shape of metal level 5 outer surfaces or teeth shape below sub-heat conductive insulating layer 4 upper and lower surface of described metal level 5 coverings, described wiring board 2.Can certainly adopt corrugated, described heat conductive insulating layer 4 adopts the silica type soft material to make, and metal level 5 employing aluminium are made and also can be adopted the metal of other good heat dissipation such as copper to make,
The heat of LED1 passes on the pad 3 by pin, insulating heat-conductive layer 4 by wiring board 2 surfaces is delivered to metal level 5 again, by metal level 5 heat is dispersed in the air, metal level 5 has improved the area of dissipation of LED1 greatly, therefore reduced the thermal resistance in the hot transmission, radiating effect is very good, can solve LED1 because of the problem of aging of heat radiation due to smooth, improve the service life of LED1, thereby reduce the integrated cost that the illumination of LED1 lamp is used.
The utility model can also comprise several screws, cross the tin hole, screw contacts with heat conductive insulating layer 4, metal level 5, screw also can conduct and distribute a part of heat, pad 3 areas strengthen and the described aperture, tin hole of crossing is strengthened, more help the heat of LED1 pin is delivered to heat conductive insulating layer 4 rapidly and passes to metal level 5, can make simultaneously wiring board about in the of 2 two surface radiatings even.
Above content be in conjunction with concrete preferred implementation to further describing that the utility model is done, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, under the prerequisite that does not break away from the utility model design, its framework form can be flexible and changeable, can the subseries product.Just make some simple deduction or replace, all should be considered as belonging to the scope of patent protection that the utility model is determined by claims of being submitted to.
