Abstract

The utility model provides an integrated thermal conductive plastic LED bulb lamp which comprises a lampshade, a lamp body, an LED light source assembly, a driving power supply and a metal screw base. The lampshade covers the upper end of the lamp body. The LED light source assembly is fixedly connected with the lamp body. The driving power supply is arranged in the lamp body. The metal screw base is in threaded connection with the lamp body. The lamp body is made from a thermal conductive plastic part. The thermal conductive plastic lamp body further comprises a metal insert which is integrally arranged in the thermal conductive plastic lamp body in an injection molding mode. According to the integrated thermal conductive plastic LED bulb lamp, the metal insert is added into the thermal conductive plastic lamp body, so that heat dissipation of thermal conductive plastics is further optimized; the cost of the thermal conductive plastics is much lower than metal currently, the plastics are superior in terms of insulation safety and plasticity, the cost of the whole lamp which is made of the thermal conductive plastics is lower than that of a lamp made from an external metal member, and the weight of the whole lamp is smaller than that of the lamp made of metal.

Description

Integrated heat-conducting plastic money LED bulb lamp

Technical field

Relate to LED light source application, based on plurality of LEDs Surface Mount, on aluminium base, using heat-conducting plastic as the LED bulb lamp of lamp body, by heat-conducting plastic transferring heat, belong to electric light source and lighting technical field.

Background technology

LED bulb of the prior art, generally include lampshade, lamp body, LED light source assembly, insulating sleeve, driving power and metal screw socket, for strengthening its lamp body of heat radiation, conventionally adopt the metal materials such as die casting aluminium or rotary extrusion aluminum, the patent No. is ZL201220201238.7, name be called LED bulb patent its disclosed LED light source assembly and be fixed on heat conduction base station, heat conduction is connected heat conduction base station with lamp body, insulating sleeve is connected in lamp body, LED light source assembly, heat conduction base station and insulating sleeve are connected in turn, insulating sleeve comprises the power storehouse portion of accommodating driving power and the insulation lamp head spinning with metal screw socket, between metal screw socket and lamp body, also by an insulating coating pipe insulation, be separated by.Obviously for guaranteeing the problem of the withstand voltage of whole lamp and insulation, must comprise insulation inner sleeve and insulating coating pipe, the many costs of parts improve, and also cause in addition assembly technology complicated.

At present, the light face bulb lamp of Gao Guangtong is few on the market, and the conduction of working of plastics heat, be not as good as all-metal, is used heat-conducting plastic still less.The light face bulb lamp size of Gao Guangtong is little, and appearance looks elegant, by using different lampshades, can reach wide-angle and low-angle effect.Shortcoming is that light face causes the interior area of dissipation contacting with air of unit interval less, and light source solder joint and power supply key components temperature are higher, affect the whole lamp life-span.

Summary of the invention

For solving above-mentioned problems of the prior art, the utility model provides a kind of integrated heat-conducting plastic money LED bulb lamp, by optimizing metal insert, strengthens as far as possible the area of metal, and plastics are together with metal injection molded arriving, by frosting transferring heat.

Scheme of the present utility model is as follows:

A kind of integrated heat-conducting plastic money LED bulb lamp, comprise lampshade, lamp body, LED light source assembly, driving power and metal screw socket, lampshade is in lamp body upper end, and LED light source assembly is fixedly connected with lamp body, and driving power is placed in lamp body, metal screw socket is threaded with lamp body, wherein, lamp body adopts heat-conducting plastic part, and this heat-conducting plastic lamp body also comprises the metal insert together with it is injection-moulded in.

Further, the outer surface of the heat-conducting plastic lamp body of described LED bulb lamp is light face.

Further, described metal insert is provided with fin.

By adopting above technical scheme, LED bulb lamp compact size of the present utility model, appearance looks elegant, by using different lampshades, can reach wide-angle and low-angle effect.By add metal insert in heat-conducting plastic lamp body, the heat radiation of heat-conducting plastic is further optimized, therefore, in outward appearance and internal structure, in heat-conducting effect, obtain a balance, on the other hand, heat-conducting plastic cost has been significantly less than metal at present, plastics advantage in insulation safety and plasticity is very outstanding, and whole lamp use heat-conducting plastic cost will be lower than metal external member, and whole lamp weight is also lighter than metal.

Accompanying drawing explanation

Fig. 1 is the component drawings of integrated heat-conducting plastic money LED bulb lamp of the present utility model;

Fig. 2 is lamp body and the sectional structure chart that is injection-moulded in metal insert wherein.

In figure, 1 ~ lampshade, 2 ~ LED light source, 3 ~ aluminium base, 4 ~ lamp body, 5 ~ metal insert, 6 ~ power supply, 7 ~ screw socket.

The specific embodiment

Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in further detail.

As shown in Figure 1, LED bulb lamp comprises lampshade 1, LED light source 2, aluminium base 3, lamp body 4, metal insert 5, driving power 6 and metal screw socket 7, lampshade 1 is connected on lamp body 4, LED light source 2 and aluminium base 3 form light source assembly, LED light source 2 means of surface weldings are connected on aluminium base 3, the upper surface of aluminium base 3 is provided with reflector layer, increases and light effect.The lower end of lamp body 4 is threaded with metal screw socket 7, and driving power 6 is placed in lamp body 4, and its power line is electrically connected to light source assembly through after being located at the cable-through hole on metal insert 5 and aluminium base 3.

As shown in Figure 2, heat-conducting plastic lamp body 4 comprises internal layer 41 and outer 42, the perisporium of metal insert 5 is injection-moulded between the inside and outside layer of lamp body 4 and forms integrated lamp body, light source assembly is fixed on metal insert 5 by sunk screw, on the periphery wall of metal insert 5, be also provided with fin 51, further strengthen radiating effect.Lamp body adopts heat-conducting plastic material, makes screw socket 7 directly be connected contact with lamp body 4, and unlike metal lamp body, need to add in addition insulated barriers connector, and assembling is simple, safety and good pressure-resistant performance.

Adopt this conceptual design to go out Japanese A60 bulb lamp, take and substitute 60w as example, use certain brand 3030 light source, adopt 9 string 3 schemes, use a input 100v 50Hz, output 55v/195ma power supply originally, is used mach heat-conducting plastic lamp body to test comparison, uses in wide-angle milky lampshade situation, after actual test light flux stabilized, can reach 1001lm, power 10.5w, light efficiency reaches 95lm/W, more than angle can reach 230 degree.
