20110074264 | LED Straight Tube Type Lamp - The invention relates to an LED straight tube type lamp which mainly solves the problems of short service life, poisoning of operators and environment pollution caused by that the lamp cover and the lamp tube are connected by chemical adhesives and unreasonable structure, poor heat diffusion effect, easy occurrence of short circuit of the lamp strip of the lamp. The LED straight tube type lamp comprises a tube body, a lamp cover sheathed at two ends of the tube body and a lamp strip which is in inserted connection in the tube body and comprises a circuit board and a heat diffuser; the lamp cover is internally, fixedly provided with a connecting device connected with the lamp strip; the connecting device comprises a connecting piece on which a connecting arm extending along the length direction of the lamp strip is arranged; the connecting arm is provided with a buckle body; the corresponding position on the surface of the lamp strip is provided with a buckle seat matched with the buckle body; and the circuit board is overlapped and adhered with the radiator to be into a whole through an insulating heat conducting layer. The LED straight tube type lamp has prolonged service life of the tube body and better heat conductibility, simultaneously, effectively improves the flame retardant ability, is difficult to have short circuit, and is used safely and reliably. | 03-31-2011 |
