Described crossbeam has several continuous projectioies towards a side of first housing, is the corrugated setting.

The two ends of described second housing are provided with connecting portion, connecting portion comprise link, stiff end and be formed at link and stiff end between draw-in groove; The two ends correspondence of described first housing is provided with the auxiliary section, the auxiliary section comprises abutting end and is located at the mating groove at abutting end middle part, the abutting end of first housing is placed in the draw-in groove of second housing, the stiff end of second housing is placed in the mating groove of first housing, and first housing is interlocked with second housing and is connected.

Described first housing and second housing are buckled into the fluorescent tube that diameter is 26mm.

The beneficial effects of the utility model: at first, aluminum alloy casing adopts unique snapping mode with combining of plastic casing, makes aluminum alloy casing and plastic casing fasten easily, and is difficult to after fastening split, and has improved the firm reliability of aluminium alloy and plastics combination; Secondly, adopt aluminum alloy casing to fasten plastic casing, can improve the LED radiating effect; Once more, adopt aluminum alloy casing structure, can improve the fluorescent tube resistance to tension greatly, improve the bending displacement of fluorescent tube, the maximum deflection displacement of fluorescent tube is less than 1mm during use; In addition, adopt aluminum alloy casing to combine with plastic casing, electric clearance and creep age distance meet TUV, the security regulations of authoritative institutions such as UL, solve LED fluorescent lamp metal shell and replaced the traditional fluorescent lamp can't earth connection in using and the safety problem that exists, thereby realized the effect of safety and heat radiation simultaneously.

In order further to understand feature of the present utility model and technology contents, see also following about detailed description of the present utility model and accompanying drawing, yet appended graphic only provide with reference to and the explanation usefulness, be not to be used for the utility model is limited.

Description of drawings

Below in conjunction with accompanying drawing,, will make the technical solution of the utility model and other beneficial effects apparent by the specific embodiment of the present utility model is described in detail.

In the accompanying drawing,

Fig. 1 is the schematic diagram of the utility model LED fluorescent tube;

Fig. 2 is the cutaway view of Fig. 1 along the 2-2 direction; And

Fig. 3 is the partial enlarged drawing of Fig. 2.

The specific embodiment

For further setting forth technological means and the decorative effect thereof that the utility model is taked, be described in detail below in conjunction with preferred embodiment of the present utility model and accompanying drawing thereof.
