Abstract

Provided is a T8D tube light-emitting diode (LED) daylight lamp, which comprises a polycarbonate (PC) diffusion cover, an LED lamp bead, a printed circuit board (PCB), an insulation sleeve, heat conductive silica gel, a power supply, an aluminum tube, a 2-T8D lamp holder, screws and the like. The heat conductive silica gel is attached to a clamping groove in the front of the aluminum tube, the insulation sleeve is arranged at a clamping position in the front of the aluminum tube, and the PCB us arranged in the insulation sleeve. The back of the aluminum tube is arranged in a trapezoid shape. The LED daylight lamp is good in visional effect, good in radiation effect and capable of ensuring service life of a lamp tube, reducing light decay of the lamp bead and prolonging service life.

Description

A kind of T8D shape pipe LED fluorescent lamp

Technical field:

The utility model relates to lighting field, relates in particular to a kind of T8D shape pipe LED fluorescent lamp.

Background technology:

Traditional fluorescent lamp is power consumption not only, and very easily damages, and once damage; Then be difficult to repair, it not only wastes energy, resource, returns the consumer and brings inconvenience; Even more serious is, traditional fluorescent tube contains mercury, and the discarded object after the damage can damage environment.

And the popular LED fluorescent lamp in market is structurally many with reference to traditional fluorescent lamp, and circular configuration is adopted at the fluorescent tube rear portion more; Visual effect is not good enough, and owing to receive the fluorescent tube size restrictions, the diffusion effect of light is undesirable; And the aluminum component of fluorescent tube is partly less; Area of dissipation is little, and radiating effect is undesirable, thereby influences the service life of fluorescent tube.

The utility model content:

The purpose of the utility model provides a kind of T8D shape pipe LED fluorescent lamp, and not only good visual effect, and excellent in heat dissipation effect has more protection the service life of fluorescent tube.

The utility model is achieved in that

A kind of T8D shape pipe LED fluorescent lamp; It is characterized in that: it is made up of PC diffusion shell, LED lamp pearl, pcb board, insulation sleeve, heat conductive silica gel, power supply, aluminum pipe and 2-T8D lamp holder, screw etc.; Heat conductive silica gel is close in the anterior draw-in groove of aluminum pipe; Insulation sleeve places in the anterior screens of aluminum pipe, and pcb board places insulation sleeve; The aluminum pipe rear portion is set to ladder type.

The lighting angle of LED lamp pearl is 150 degree; LED lamp pearl center is set to 8.33mm to the horizontal range of PC diffusion shell, vertically highly is set to 10.67mm.

The beneficial effect of the utility model is that aluminum pipe is broken through traditional circular configuration, does latter half in echelon, makes external form more attractive in appearance, and heat dispersion is better, but does not influence assembling; Adopt diffusion shell to press the mode of pcb board, leg is better contacted with heat conductive silica gel, make lamp pearl radiating effect better, more can reduce the light decay of lamp pearl, life-saving.

The specific embodiment

Like Fig. 1, Fig. 2, Fig. 3, shown in Figure 4; A kind of T8D shape pipe LED fluorescent lamp; Be made up of PC diffusion shell (1), LED lamp pearl (2), pcb board (3), insulation sleeve (4), heat conductive silica gel (5), power supply (6), aluminum pipe (7) and 2-T8D lamp holder (8), screw (9) etc., LED lamp pearl (2) is intersected, is arranged on pcb board (3) front regularly.During installation; Elder generation's heat conduction silica gel (5) is adjacent in the draw-in groove of aluminum pipe (7) front portion, insulation sleeve (4) is placed in the anterior screens of aluminum pipe (7) again, and back pcb board (3) places insulation sleeve (4); Use PC diffusion shell (1) to compress pcb board (3) at last; Impel pcb board (3) and heat conductive silica gel (5) to paste more compactly, increase the capacity of heat transmission, power supply (6) is installed in the back side of pcb board (3).

The mounting means of lamp pearl (2) can adopt SMD or plug-in type, all can reach bright dipping evenly, shadow-free, no black surround, perfection that light is soft go out light effect.Power supply (6) is installed in the back side of pcb board (3), has increased the security that fluorescent tube uses, and PC diffusion shell (1) is that transparency is high, high temperature resistant, printing opacity is good; Light transmittance reaches 84.2%; Have good diffusion function, aluminum pipe (7) is made traditional round tube that ladder type compares, and radiating effect is more excellent.Between the input ac voltage 100-240V, become direct current,, reach required direct current, supply with the acting of light-emitting diodes light then through control and reduction voltage circuit through rectifying and wave-filtering.After adding forward voltage to light emitting diode, be injected into the hole in N district from the P district and be injected into the electronics in P district by the N district, near PN junction in several microns respectively with the electronics in N district and the hole-recombination in P district, produce the fluorescence of spontaneous radiation.The lighting angle of LED lamp pearl (2) is 150 degree, 8LM/PCS, and horizontal positioned, LED lamp pearl (2) center is set to 8.33mm to the horizontal range of PC diffusion shell (1), vertically highly is set to 10.67mm.
