Abstract
The utility model discloses a stable light-emitting diode (LED) bulb comprising a heat dissipation device (2) and a printed circuit board (PCB) (4) arranged on the heat dissipation device (2), wherein a plurality of LED lamps (6) are installed on the PCB (4), the bottom of the PCB (4) is provided with two insertion pieces (8) at intervals, the insertion pieces (8) are in electrical connection with electrodes on the PCB (4), and the heat dissipation device (2) is provided with power supply sockets (10) corresponding to the insertion pieces (8). The stable LED bulb is characterized in that two opposite side walls of the insertion pieces (8) are respectively provided with an elastic protrusion (81), and inner walls of the power supply sockets (10) are provided with concave holes (11) corresponding to the protrusions (81). The stable LED bulb is firm, reliable, and stable in lamination.
Description
Technical field
The utility model relates to a kind of bulb, relates in particular to a kind of LED bulb of stable type.
Background technology
LED light is as a kind of house lighting for substituting tengsten lamp and fluorescent lamp, because it has that energy consumption is little, light efficiency is large, without advantages such as mercury, radiationless pollution and material reproducible utilizations, in today of energy growing tension, more and more be subject to consumer's welcome.Radiator normally adopts many screws to be fixedly connected with pcb board in the present employed LED bulb, and the power line that passes radiator normally is welded on the pcb board, this kind connected mode, not only cause LED bulb operation when assembling more loaded down with trivial details, but also can cause pcb board to damage because welding is improper.Also there is at present in addition a kind of LED bulb, the bottom interval of its pcb board is provided with two inserted sheets, described inserted sheet is electrically connected with electrode on the described pcb board, have the supply hub corresponding with described inserted sheet on the described radiator, although this kind is convenient and swift when assembling by the connected mode that inserted sheet cooperates with jack, but it is when meeting with collision, and inserted sheet easily comes off from jack, the phenomenon of color break-up also easily occurs because of inserted sheet and jack loose contact.
The utility model content
It is firm that technical problem to be solved in the utility model provides a kind of connection, the stable type LED bulb of stable luminescence.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of stable type LED bulb, comprise radiator and be installed in pcb board on the radiator, the plurality of LEDs lamp is installed on the described pcb board, the bottom interval of described pcb board is provided with two inserted sheets, described inserted sheet is electrically connected with electrode on the described pcb board, have the supply hub corresponding with described inserted sheet on the described radiator, but be respectively arranged with the projection of elastic telescopic on relative two sidewalls of described inserted sheet, have the shrinkage pool corresponding with described projection on the inwall of described supply hub.
Be provided with one deck heat-conducting glue between described pcb board and the described radiator.
The end of described projection is smooth sphere.
Compared with prior art, the beneficial effects of the utility model are:
Because but stable type LED bulb of the present utility model is provided with the projection of elastic telescopic at inserted sheet, inwall at supply hub is provided with the shrinkage pool corresponding with projection, can effectively prevent that with cooperating of shrinkage pool inserted sheet from directly coming off by projection in supply hub, therefore the utility model is fixed, stable luminescence.
Description of drawings
Describe the utility model in detail below in conjunction with drawings and embodiments
Fig. 1 is structural representation of the present utility model.
Among the figure: radiator 2, pcb board 4, LED lamp 6, inserted sheet 8, supply hub 10, projection 81, shrinkage pool 11.
The specific embodiment
As shown in Figure 1, a kind of stable type LED bulb of the present utility model, comprise radiator 2 and be installed in pcb board 4 on the radiator 2, on this pcb board 4 plurality of LEDs lamp 6 is installed, the bottom interval of pcb board 4 is provided with two inserted sheets 8, this inserted sheet 8 is electrically connected with electrode on the pcb board 4, have the supply hub 10 corresponding with inserted sheet 8 on the radiator 2, special feature of the present utility model is: but be respectively arranged with the projection 81 of elastic telescopic on relative two sidewalls of inserted sheet 8, have on the inwall of supply hub 10 and protruding 81 corresponding shrinkage pools 11, can effectively prevent that with cooperating of shrinkage pool 11 inserted sheet 8 from directly coming off by protruding 81 in supply hub 10, thereby make the utility model fixed, stable luminescence.
In addition, between pcb board 4 and radiator 2, be provided with one deck heat-conducting glue 12 for further strengthening heat dispersion of the present utility model, can effectively increase heat exchange area between pcb board 4 and the radiator 2 by this layer heat-conducting glue 12, for the end that makes inserted sheet 8 easily extract projection 81 in the supply hub 10 is set to smooth sphere.
In sum, the utility model is fixed, stable luminescence.
The above only is preferred embodiments of the present utility model; protection domain of the present utility model is not limited with above-mentioned embodiment; as long as the equivalence that those of ordinary skills do according to the utility model institute disclosure is modified or changed, all should include in the protection domain of putting down in writing in claims.
Claims (3)
1. stable type LED bulb, comprise radiator (2) and be installed in pcb board (4) on the radiator (2), plurality of LEDs lamp (6) is installed on the described pcb board (4), the bottom interval of described pcb board (4) is provided with two inserted sheets (8), described inserted sheet (8) is electrically connected with electrode on the described pcb board (4), have the supply hub (10) corresponding with described inserted sheet (8) on the described radiator (2), it is characterized in that: described inserted sheet (8) but be respectively arranged with the projection (81) of elastic telescopic on relative two sidewalls, have the shrinkage pool (11) corresponding with described projection (81) on the inwall of described supply hub (10).
