Abstract
The utility model discloses an LED fluorescent tube, comprising a heat radiating cover, a light shade, two lamp holder covers and an LED circuit board which is pivot-arranged in the lamp shade, wherein the circuit board is electrically connected with electrodes fixed on the lamp holder covers, a locking recess is arranged inside the lower end of the heat radiating cover, and both lateral ends of the circuit board are correspondingly locked in the locking recess. Compared with prior art, the LED fluorescent tube can directly replace common fluorescent tubes without changing other parts in fluorescent lamps, and is convenient to assemble and disassemble. The LED circuit board is fixed in the heat radiating cover to form a large cavity, thus heat generated by LED luminescence can be quickly radiated by the heat radiating cover, thereby lowering temperature of the LED fluorescent tube.
Description
Technical field:
The utility model belongs to lighting field, and particularly a kind of is the fluorescent tube of light source with the LED lamp.
Background technology:
Fluorescent lamp is as cold light source, and is more energy-conservation than conventional incandescent, therefore is widely used in industry and domestic lighting, and accessories such as the lamp socket supporting with it, lamp bracket and lamp box have formed standard.Along with the development of new-type light source led, it is inevitable that its application at lighting field has become.
LED lamp type and traditional fluorescent lamp greatly differ from each other at present, therefore it need be designed to the fluorescent lamp shape, but present LED fluorescent lamp, generally manufacture an integral body with body, when body damages, also to scrap even the LED light emitting module is intact thereupon, cause the wasting of resources easily.
The utility model content:
For this reason, the purpose of this utility model is to provide a kind of LED fluorescent tube, can dismantle between the circuit board of this fluorescent tube heat dissipating housing, lampshade and welding LED, has great convenience for the user installation, and can be recycled, and has avoided waste.
For achieving the above object, the utility model is mainly by the following technical solutions:
A kind of LED fluorescent tube, the lamp holder that comprises heat dissipating housing (1), lampshade (2), two ends covers (3), is hubbed at the circuit board (4) that is welded with LED in the lampshade, circuit board (4) is electrically connected with electrode (301) on being fixed on lamp holder lid (3), described heat dissipating housing (1) lower end arranged outside has draw-in groove (101), the inboard is provided with draw-in groove (103), and circuit board (4) two side ends correspondence is placed in the above-mentioned draw-in groove (103).
Described lampshade (2) upper end is provided with hooked hand (201), and the corresponding inlay card of this hooked hand (201) is in draw-in groove (101).
Be welded with power supply (5) on the described circuit board (4).
Described heat dissipating housing (1) is made by aluminium base sheet material.
Described heat dissipating housing (1) lower end is provided with screw (102).
Described lampshade (2) is made by transparent material.
Compared with prior art, the utility model directly replaces fluorescent tube to use, and need not to change miscellaneous part in the fluorescent lamp device, and dismounting and installation are all very convenient; Simultaneously the led circuit plate is fixed in the heat dissipating housing, and and heat dissipating housing between form bigger cavity, thereby the heat that produces when making LED luminous can be exhaled by heat dissipating housing rapidly, thereby reduce the temperature of LED fluorescent tube.
