The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described:
As Fig. 1, Fig. 2 and explosive view of the present utility model shown in Figure 3, the LED electricity-saving lamp among the figure comprises lamp body, drive circuit 20, connector and connect-disconnect plug 10.Connector connects lamp body and connect-disconnect plug 10.Described connector comprises connector 30, fastener 40 and rotary connecting joint 50, one end of rotary connecting joint 50 is for connecting the link 501 of lamp body, the other end is a round end 503, and two ends link together by connecting shaft 502, and the external diameter of round end 503 is bigger than the external diameter of connecting shaft 502.The middle part of rotary connecting joint 50 is provided with via hole 504, and link 501 is provided with connecting hole 505.Fastener 40 is divided into two parts symmetrical, is fastened on simultaneously on the connector 30, forms connecting shaft hole 401 at the middle part.The connecting shaft 502 of rotary connecting joint 50 passes connecting shaft hole 401, round end 503 and link 501 lay respectively at the both sides of fastener 40, and the external diameter of round end 503 and link 501 makes when fastener 40 fastens all greater than the aperture in connecting shaft hole 401, rotary connecting joint 50 can only rotate, and can not pull out.Fastener 40 latches in rotary connecting joint 50 at an end of connector 30, this end is provided with an inside groove 301, be provided with locating convex block 302 in the groove, the round end 503 of rotary connecting joint 50 places inside groove 301, and 302 of locating convex blocks place the vacancy (referring to Fig. 5) between round end 503 and the inside groove 301.The other end of connector 30 connects connect-disconnect plug 10, and its middle part is provided with through hole, when connector 30 is connected with connect-disconnect plug 10, forms a cavity in the centre, and drive circuit 20 places in this cavity, and input connects the metal pin of connect-disconnect plug 10, and output then connects lamp body.Lamp body comprises light cover 90, radiator 60, reflector 70 and LED 80.Radiator 60 is fixed on the rotary connecting joint 50 by the connecting hole on the link 501 505, and the fin 601 that its back is provided with can increase area of dissipation effectively, improves radiating efficiency.Reflector 70 is close together by the effect and the radiator 60 of screw 701, which is provided with LED 80, these LED 80 can be arranged in different shapes as required, as are arranged in rectangle, circle or irregularly shaped etc., and the number of LED 80 also can increase or reduce according to the needs of illumination.These LED 80 connect the output of drive circuit 20, and external power source is powered by connect- disconnect plug 10 and 20 couples of LED 80 of drive circuit, makes its operate as normal.Light cover 90 covers on radiator 60, thereby reflector 70 and LED 80 are enclosed in the inner chamber that light cover 90 and radiator 60 surround.The stereoscopic figure of this lamp as shown in Figure 4, the light that LED 80 sends sees through light cover 90 irradiations and comes out, and wherein a part of light is radiated on the reflector 70, sees through light cover 90 by reflector 70 reflection backs and penetrates, thereby made full use of the light that LED 80 sends, improved the efficient of illumination.Adjust the angle of illumination if desired, only need reverse lamp body, because the restriction of locating convex block 302, lamp body can not rotate by 360 deg, by the setting to locating convex block 302 positions and size, can realize that lamp body rotates arbitrarily in the 360 deg.
