2) lamp pearl wiring board is fixed on the plastic cement seat by screw with heat-conducting plate, keep excellent contact, the heat of the generation when the lamp pearl is luminous can be derived by heat-conducting plate, the edge of heat-conducting plate is designed to dome shape according to the cavity shape of radiator, when lamp holder screws with the plastic cement seat, heat-conducting plate can keep excellent contact with aluminium radiator, the heat that produces on the lamp pearl wiring board just can be derived by heat-conducting plate like this, on radiator, radiator looses heat and removes, and ensures that the lamp pearl can not replace using always radiating seat with light aluminium radiator simultaneously because of overheated and burn out, can reduce the cost of bulb lamp significantly, alleviate the weight of product.
3) lamp pearl wiring board is provided with the long no wiring region of the 6mm width of cloth at least, safing creep age distance with the periphery of driving power.
The specific embodiment
Below in conjunction with accompanying drawing the utility model bulb lamp is described in further detail.
As shown in Figure 1-Figure 3, the utility model bulb lamp, comprise lamp holder 1, lampshade 2, driving power 3, plastic cement seat 4, heat-conducting plate 5, lamp pearl wiring board 6 and radiator 7, driving power 3 is installed on the plastic cement seat 4, lamp pearl wiring board 6 is located on the heat-conducting plate 5, lamp pearl wiring board 6, heat-conducting plate 5 is fixedlyed connected with plastic cement seat 4, driving power 3 and lamp pearl wiring board 6, lamp holder 1 circuit connects, lampshade 2 is connected with plastic cement seat 4, driving power 3, heat-conducting plate 5, lamp pearl wiring board 6, lampshade 2 constitutes plastic cement cover for seat part with plastic cement seat 4, radiator 7 is provided with inner chamber 71, the plastic cement cover for seat part that fixes inserts lumen of radiator 71, plastic cement seat 4 tops are stretched into lumen of radiator and are stretched out radiator, and it is fixedly connected with lamp holder to put a retaining ring 8 back.As seen radiator 7 is fixedlyed connected with plastic cement seat 4 by retaining ring 8.Wherein lampshade 2 is provided with four button bits, and plastic cement seat 4 tops are provided with four screens, and four button bits of lampshade 2 are connected with four screens of plastic cement seat 4, retaining ring 8 be provided with four screens and with four clamping matching on plastic cement seat top.Four screens on plastic cement seat 4 tops are four positioning bars.Lumen of radiator is rotation shape inner chamber, constitute by big end, small end and middle linkage section, radiator 7 small end endoporus are provided with four locating notches, four positioning bars on plastic cement seat 4 tops are with after four locating notches of radiator 7 small end endoporus cooperate, and it is fixedly connected with the screw thread of lamp holder 1 to stretch out radiator.
Lamp pearl wiring board 6 is fixed by screw with heat-conducting plate 5, and the edge of heat-conducting plate 5 is provided with the planar structure 51 that the cavity shape with radiator is complementary, as be conical surface-shaped, and assurance heat-conducting plate 5 closely contacts with the lumen of radiator wall.As Fig. 2, shown in Figure 3, on the plastic cement seat, be provided with power supply deck 41, plastic cement seat bottom is provided with lampshade buckle 42, plastic cement seat top ends is provided with screw thread 43, driving power input ply-yarn drill position 44, positioning bar 45, on plastic cement seat wall, be provided with screw joint pin 46, driving power 3 is inserted on the power supply deck 41, and the wall of the outside wall surface of lamp socket 4 and lumen of radiator 71 is complementary.Be provided with the long no wiring region of the 6mm width of cloth at least in the periphery of lamp pearl wiring board 6 and driving power 3.
In the utility model bulb lamp, because driving power 3 directly is inserted on the power supply deck 41 of plastic cement seat, lamp pearl wiring board 6, heat-conducting plate 5 are fixed on the plastic cement seat successively by screw 9, the plastic cement cover for seat part that fixes is inserted in lumen of radiator 71, small end cover upper locking ring 8 at radiator 7 screws lamp holder 1 again, buckles lampshade 2 at last, bulb lamp just assembling is finished, and is as seen easy to assembly; Because lamp pearl wiring board 6 is fixed by screw with heat-conducting plate 5, keep excellent contact, the heat that produces when the lamp pearl is luminous can be derived by heat-conducting plate 5, the edge of heat-conducting plate 5 is designed to conical surface-shaped according to the cavity shape of radiator, when lamp holder 1 screws with the plastic cement seat, heat-conducting plate 5 can keep excellent contact with aluminium radiator, the heat that produces on the lamp pearl wiring board 6 just can be derived on radiator 7 by heat-conducting plate 5 like this, radiator looses heat and removes, ensure that lamp pearl 61 can be because of not overheated and burn out, replace common heat sink with light aluminium radiator simultaneously, can reduce the cost of bulb lamp significantly, alleviate product weight; Owing to follow the periphery of driving power that the long no wiring region of the 6mm width of cloth at least all is set at lamp pearl wiring board, like this with regard to secure safe creep age distance.
