Description of drawings
Fig. 1 is the generalized section of the utility model LED lamp.
Fig. 2 be the utility model LED lamp can external controllable silicon light modulation circuit the formation schematic diagram.
The specific embodiment
Below in conjunction with description of drawings and the specific embodiment the utility model is further specified.
See also Fig. 1 and Fig. 2, the utility model provides a kind of LED lamp 10, comprise fluorescent tube 11, termination 13, pcb board 15 and a plurality of luminescence unit 17 that is arranged at pcb board 15, described termination 13 is arranged at described fluorescent tube 11 two ends, described pcb board 15 is arranged in the described fluorescent tube 11 and be connected in described termination 13, described LED lamp 10 also is provided with pcb board support member 19, described pcb board support member 19 comprises main body 191 and is connected in the support portion 193 of main body 191, described main body 191 is held in described pcb board 15, and described support portion 193 is held in the inboard of described fluorescent tube 11.
In the present embodiment, described fluorescent tube 11 adopts glass round tube.The main body 191 of described pcb board support member 19 is that sheet and the support portion 193 that fits in described pcb board 15 described pcb board support members 19 are the arc sheet, and its middle part is held in the inboard of described fluorescent tube 11.Described pcb board support member 19 adopts elastic metallic to make.Described pcb board 15 adopts aluminium base.Be understandable that the termination 13 of LED lamp 10 is identical with the structure of existing existing termination, is provided with parts such as power line, lamp holder electrode, does not repeat them here.
