Background technology

Conventional incandescent (tengsten lamp) power consumption is high, life-span is short, under the overall situation of global resources anxiety, gradually, forbidden producing by national governments, because LED(Light Emitting Diode, light emitting diode) is a kind of solid-state semiconductor devices that electric energy can be converted into visible light, it can directly be converted into luminous energy to electric energy, it is little that LED has a volume, power consumption is low, long service life, environmental protection, sturdy and durable, the brightness advantages of higher, extensive use in daily life, as the LED bulb lamp, the LED bulb lamp is the novel energy-conserving light fixture that substitutes the conventional incandescent bulb.

Existing LED bulb lamp comprises lamp holder, lamp socket, radiator, diffuser, light source etc., connected mode between radiator and the diffuser has following three kinds: first, by radiator is attacked thread, diffuser is threaded with the radiator utilization, thereby but the screw thread in this mode take place easily looseningly to cause coming off; The second, the diffuser edge is provided with protruding bar, with defeating diffuser, rib is slided in the draw-in groove of radiator, and the production efficiency of this mode is low, dismounting, reprocesses (maintenance) inconvenience; The 3rd, the radiator draw-in groove is coated with silica gel, makes diffuser and radiator utilize the caking property of silica gel and is connected, and the production efficiency of this mode is low, dismounting, reprocesses (maintenance) inconvenience.

The utility model content

Technical problem to be solved in the utility model provides a kind of LED bulb lamp, and its ease of assembly and dismounting are enhanced productivity, and prevents that diffuser and radiator are loosening and cause coming off.

The utility model solves above-mentioned technical problem by following technical proposals: a kind of LED bulb lamp, comprise led light source, diffuser and radiator, and the top of diffuser is provided with grab, and the bottom of radiator is provided with buckle, and grab engages with buckle.

Preferably, the top of described diffuser is provided with first edge, and gapped between grab and first edge, grab is positioned at the outside at first edge.

Preferably, the bottom of described grab is provided with positioning bar.

Preferably, the centre of described grab is provided with groove, and groove is between hypotenuse and positioning bar.

Preferably, the bottom of described radiator is provided with second edge, and buckle is positioned at the inboard at second edge.

Preferably, the strip that is shaped as bending of described buckle.

Preferably, the outer surface of described radiator is provided with fin.

Preferably, described LED bulb lamp also comprises lamp socket and lamp holder, and an end and the radiator of lamp socket are fixed, and the other end of lamp socket is connected with cap screw thread.

Positive progressive effect of the present utility model is: the utility model is rotated in a clockwise direction diffuser, make grab on the diffuser block buckle on the radiator, the buckle of radiator is slided in the grab of diffuser, assemble more conveniently like this, enhance productivity.

The specific embodiment

Provide the utility model preferred embodiment below in conjunction with accompanying drawing, to describe the technical solution of the utility model in detail.

As Fig. 1, Fig. 2, shown in Figure 6, the utility model LED bulb lamp comprises led light source (not shown), diffuser 1 and radiator 2, the top of diffuser 1 is provided with a plurality of grabs 11, the bottom of radiator 2 is provided with a plurality of buckles 21 mutual corresponding with the position of a plurality of grabs 11, and per two corresponding grabs 11 engage with buckle 21.

As Fig. 3, Fig. 4, Fig. 5, shown in Figure 6, the top of diffuser 1 is provided with first edge 12, and grab 11 is positioned at the outside at first edge 12, and the top of grab 11 is provided with hypotenuse 111, gapped 114 between grab 11 and first edge 12, gap 114 begins to extend to the middle part of grab 11 from hypotenuse 111.The bottom of grab 11 can be provided with positioning bar 112, and positioning bar 112 can prevent effectively that diffuser from rotating too along clockwise direction.In addition, the centre of grab 11 is provided with groove 113, groove 113 is between hypotenuse 111 and positioning bar 112, grab 11 is with after buckle 21 engages, buckle 21 is positioned at groove 113, buckle 21 just can not move like this, thereby assurance diffuser 1 and radiator 2 are fixed, and hypotenuse 111 makes things convenient for buckle 21 to be slipped in the groove 113.Gapped 114 between grab 11 and first edge 12, gap 14 makes grab 11 have certain elasticity, can form a screen resilience; When grab 11 pushed with buckle 21, the gap dwindled, and makes things convenient for buckle 21 to snap in the groove 113; After buckle 21 snapped in groove 113, buckle 21 was blocked in the gap resilience; When grab 11 forwarded certain position to, grab 11 was upspring automatically, thereby prevented that diffuser and radiator are loosening and cause coming off, and improved the quality of products.

As shown in Figure 7 and Figure 8, the bottom of radiator 2 is provided with second edge 22, and buckle 21 is positioned at the inboard at second edge 22, the strip that is shaped as bending of buckle 21.The outer surface of radiator 2 is provided with fin 23, increases area of dissipation like this, improves radiating effect.The top of radiator 2 is provided with screw hole 24.

As Fig. 1, Fig. 8, Fig. 9, shown in Figure 10, the utility model LED bulb lamp also comprises lamp socket 3 and lamp holder 4, one end of lamp socket 3 and radiator 2 are fixing, the side of lamp socket 3 is provided with through hole 31 specifically, it is fixing with screw hole 24 that screw or bolt pass through hole 31 backs, so just an end and the radiator 2 of lamp socket 3 fixed.The other end of lamp socket 3 is threaded with lamp holder 4, and the top of lamp socket 3 is provided with first screw thread 32 specifically, and lamp holder 4 is provided with second screw thread, 41, the first screw threads 32 and is threaded with second screw thread 41, and the other end of lamp socket 3 is realized being threaded with lamp holder 4 like this.

The utility model LED bulb lamp is rotated in a clockwise direction diffuser, makes grab on the diffuser block buckle on the radiator, namely can make radiator and diffuser fixed easily, assembles more conveniently like this, enhances productivity.The top of grab is provided with hypotenuse, and hypotenuse makes things convenient for buckle to slide and the location.Gapped between grab and first edge, make grab have certain elasticity, convenient buckle is blocked, make between diffuser and the radiator cooperate tightr.When grab and buckle forwarded certain position to, grab was upspring automatically, thereby prevented that diffuser and radiator are loosening and cause coming off, and improved the quality of products.When the LED bulb lamp needs dismounting, the grab of diffuser is pressed, along rotating counterclockwise just can outward winding diffuser and radiator, can easy disassembly, and the scrappage of reduction product.The bottom of grab is provided with positioning bar, and positioning bar can prevent effectively that diffuser from rotating too along clockwise direction.

Those skilled in the art can carry out various remodeling and change to the utility model.Therefore, the utility model has covered various remodeling and the change in the scope that falls into appending claims and equivalent thereof.
