Abstract

The utility model relates to an LED lamp tube comprising a lampshade, a heat radiation lampshell and an LED luminophor component. The heat radiation lampshell comprises a mounting seat and a heat radiation cover which are integrally formed, the mounting seat is provided with a slot disposed along the length direction and bosses arranged on two sides of the slot and extending along the length direction of the heat radiation lampshell, the surface of each boss is provided with an inclined surface inclined outwardly from the slot, and the surfaces of the bosses are arranged in an inverted-Y-shaped structure. A fastening slot connected with the lampshade in an inserted manner is formed at the outer edge of each boss, and an included angle formed between the surfaces of the bosses ranges from 135 degrees to 145 degrees. Since the surfaces of the bosses form an inverted-Y-shaped structure reasonable in angle, light emitted from an LED luminophor is centrally emitted from the lampshade after reflected by the surfaces of the bosses, so that the lamp tube can be quickly assembled and has an excellent reflection function, and the lamp tube has better lighting effect with the same power.

Description

LED fluorescent tube

Technical field

The utility model relates to a kind of lighting, specifically a kind of fluorescent tube of fluorescent lamp of LED illuminator.

Background technology

Above-mentioned LED luminous component comprises again circuit board and is arranged on the LED illuminator on this circuit board, and general, circuit board is to be arranged on heat radiation lampshade by screw, but this Standard inefficiency.For this reason, people have and are designed with the slot of arranging along its length at heat-dissipation lamp housing, and circuit board is plugged in this slot, thereby can improve significantly assembling speed.Can even now, in use find, though heat-dissipation lamp housing has good thermolysis at present, but reflection action is unsatisfactory, as the structure of disclosed heat-dissipation lamp housing in the Chinese patent application publication No. < < LED fluorescent lamp > > that is CN102022651A.Thereby can affect to a certain extent lighting effect.

Utility model content

Technical problem to be solved in the utility model is the present situation for prior art, and a kind of LED fluorescent tube when realizing assembling fast with better reflecting effect is provided.

The utility model solves the problems of the technologies described above adopted technical scheme: a kind of LED fluorescent tube, include lampshade, heat-dissipation lamp housing, LED luminous component and LED drive circuit and respectively with the first end cap of a pair of lamp base, the second end cap, wherein heat-dissipation lamp housing comprises integrated mount pad and heat dissipating housing, on described mount pad, have the slot of arranging along its length, described first, the second end cap is separately fixed at the two ends after described lampshade is connected with heat-dissipation lamp housing, described LED luminous component comprises again circuit board and is arranged on the LED illuminator on this circuit board, described circuit board is plugged in the slot of described mount pad, described LED drive circuit is positioned at the die cavity of heat-dissipation lamp housing, it is characterized in that: on described mount pad, there is the boss that is positioned at described slot both sides and extends along described heat-dissipation lamp housing length direction, the surface design of each boss becomes to make the surface of two boss be arranged to splayed structure from the outward-dipping inclined-plane of slot, the outer side edges of each boss also forms along upper the draw-in groove that inserting connects described lampshade, and, between the surface of two described boss, form the angle of 135 °～145 °.

Preferably, between the surface of described two boss, form the angle of 142 °.By test, show, the reflecting effect under this angle is better.

In above-mentioned each scheme, on described circuit board, be welded with female connector that negative electrode, anode with LED illuminator are electrically connected, the wire of the power output end of described LED drive circuit is plugged on Male connector, and described female connector is connected with the inserting of Male connector phase.The power output end of LED drive circuit can be realized and being connected fast with LED illuminator by this male and female connector like this.

Be preferably, between described circuit board and slot bottom, be bonded with two-sided heat conduction adhesive tape, both realized firm connection, there is again good thermolysis.

Compared with prior art, because the utility model is designed with the boss that is positioned at slot both sides on the mount pad of heat-dissipation lamp housing, the surface of two boss forms the splayed structure of reasonable angle, therefore, after LED illuminator emits beam, through the reflection of this two boss surface, light is intensively penetrated from lampshade, thereby such fluorescent tube is also having good reflection action in realization assembling fast, makes light fixture under Same Efficieney, have better lighting effect.

The specific embodiment

Below in conjunction with accompanying drawing, embodiment is described in further detail the utility model.

As shown in Figures 1 to 6, this fluorescent tube includes lampshade 1, heat-dissipation lamp housing 2, LED luminous component 3 and respectively with the first end cap and second end cap of a pair of lamp base, wherein heat-dissipation lamp housing 2 comprises integrated mount pad 21 and heat dissipating housing 22, on mount pad 21, have the slot 211 of arranging along its length, be positioned at and on the mount pad of slot both sides, also there is the boss 212 extending along heat-dissipation lamp housing length direction, the surface design of each boss becomes to make the surface of two boss be arranged to splayed structure from the outward-dipping inclined-plane of slot, and, between the surface of two boss 212, formed the angle α of 135 °～145 °, in the present embodiment, angle α is preferably 141 ° or 142 °.
