The specific embodiment

Below in conjunction with drawings and Examples the utility model is described in further detail.

As shown in Figure 1, comprise lamp holder 10, lamp socket 20, connector 30 and circuit board according to light fixture of the present utility model.Lamp holder 10 comprises radiating seat 13 and is installed in lens 11 and LED12 in the radiating seat 13.Lamp socket 20 inside are equipped with the circuit board (not shown).Connector 30 is installed on the lamp socket 20, is used for being connected with external power source.Circuit board links to each other with connector 30 with LED12 respectively.Lamp holder 10 is removably mounted on the lamp socket 20, changes so that lamp holder 10 and lamp socket 20 can be distinguished separately, for example, when circuit board damage, can take lamp holder 10 and lamp socket 20 apart, thereby change circuit board, lamp holder 10 can continue to use, thereby can reach cost-effective purpose.

In an example of the present utility model, lamp holder 10 is provided with claw 201, and lamp socket 20 is provided with draw-in groove 131, thereby lamp holder 10 is installed on the lamp socket 20 by the joint of claw 201 and draw-in groove 131.Direction of rotation A rotation lamp holder 10 according to shown in Figure 1 just can make the claw 201 of lamp holder 10 closely be bonded on the draw-in groove 131 of lamp socket 20, obtains the light fixture of shape as shown in Figure 2 thereby install.Certainly, the mode that is installed on the lamp socket 20 of lamp holder 10 is not limited to above-mentioned concrete example.

In a concrete example of the present utility model, circuit board is removably mounted in the lamp socket 20, so that be damaged and other parts of lamp socket 20 can also normally use the time at circuit board, only needing to change circuit board gets final product, improve the utilization rate of lamp socket 20 other parts, thereby can further save cost.

In the light fixture according to the utility model embodiment, lens 11 are arranged at the top of LED12, roughly are the bowl dress, and it is provided with three positions that LED can be installed.Handle through frosted the upper surface of lens 11, and all the other each faces are that letter out is handled.For guaranteeing the illumination effect of light fixture, lens 11 should guarantee the no any damage in surface, burr or flaw in process of production.

LED has advantages such as low, the luminous stable and long service life of energy consumption.LED12 is installed on the circular sheet that has breach and a screw, and breach on the thin plate and screw can together act on LED12 is positioned.In addition, also be provided with three circular holes that are arranged in equilateral triangle on the thin plate, so that three LED12 are installed.Certainly, the LED light emitting diode also can be replaced with other light-emitting components.

Fig. 3 shows the structure according to radiating seat 13 in the lamp holder 10 of the utility model embodiment.Radiating seat 13 is made by the die casting aluminium material for having the frustum cone structure of equally distributed flabellum, and the heat that can produce in the course of the work LED12 effectively dispels the heat.The less end of radiating seat 13 diameters is provided with four equally distributed draw-in grooves 131 that extend internally, and the distance between per two adjacent draw-in grooves 131 equates, can be used for and lamp socket 20 more firm being bonded together.

Fig. 4 and Fig. 5 show the structure according to the lamp socket 20 of the utility model embodiment.Lamp socket 20 can be made by white high-temperature resistance plastice, any surface finish and do not have any damage and flaw.One end section of lamp socket 20 is circular, and extends outward four claws 201, and these four claws 201 are corresponding with four draw-in grooves 131, and the end of each claw 201 also is provided with jut, so can be bonded together very closely.When lamp holder 10 is installed with lamp socket 20, in the space that claw 201 inserts between the draw-in grooves 131, and then along direction of rotation A rotation lamp holder 10 so that claw 201 can engage accordingly with draw-in groove 131.The other end cross section of lamp socket 20 is rectangle or round rectangle, offers two through holes on it and can pass through for the contact pin of connector 30.

Connector 30 is the form of pin, the one end be connected external power source, the other end is electrically connected with circuit board.Circuit board is connected with LED12 by lead 7.In order to make in lamp holder 10 and lamp socket 20 disassembly processes, the internal circuit of light fixture connects also can in time finish and disconnects and be connected, and LED12 can be designed to the removably that male plug matches with female plug with lead 7 between the circuit board.For example can be provided with male plug 62 at lead 7 ends of drawing from LED12, lead 7 ends of drawing from circuit board are provided with the female plug 61 that cooperates with male plug 62, can certainly be provided with female plug 61 at lead 7 ends of drawing from LED12 as shown in Figure 1, lead 7 ends of drawing from circuit board are provided with the male plug 62 that cooperates with female plug 61.

Because lamp holder 10 can disassemble from lamp socket 20 neatly in the technical solution of the utility model, therefore when the LED12 of lamp holder 10 or the circuit board in the lamp socket 20 break down separately, only need to change that some of wherein damaging, and light fixture integral body need not be abandoned, thereby provide cost savings effectively.

More than disclosed only be embodiment of the present utility model, can not limit rights protection scope of the present utility model with this certainly.Be appreciated that the equivalent variations of doing according to the utility model essence defined in the appended claims and scope, still belong to the scope that the utility model is contained.
