Description

The reflex housing of flat-panel screens module backlight

Technical field

The invention relates to a kind of light source reflecting housing, refer to a kind of reflex housing that is applicable to flat-panel screens module backlight especially.

Background technology

In flat-panel screens module backlight, its as shown in Figure 1, generally comprise light source (for example fluorescent tube) 50, reflex housing 60, with lead 70; Wherein lead is to be pressed on fluorescent tube 50 in order to provide to power up, and produces visible light; Reflex housing then is that the light that fluorescent tube is launched is reflexed to a specific direction, improves the utilization factor of light.

The assembling mode of general module backlight, for the fluorescent tube fixed placement that will have lead earlier in reflex housing, on the fluorescent tube reflex housing, directly paste double faced adhesive tape again, paste lamp tube wire subsequently on double faced adhesive tape, with the fixed lamp tube lead on the fluorescent tube reflex housing; The fluorescent tube fixed placement that perhaps will have lead earlier is positioned over lamp tube wire on the reflex housing in reflex housing again, with adhesive tape fixed lamp tube lead on the fluorescent tube reflex housing.Yet the method for utilization can suffer from following difficulty:

(1), the fixed lamp tube lead on the fluorescent tube reflex housing, depend on the stickability of double faced adhesive tape or adhesive tape; When stickability lost efficacy, lead promptly can't be fixed;

(2), it is manually-operated in general fixing cord method, so double faced adhesive tape or adhesive tape paste position there is no the location, causes the inconvenience of operating personnel when pasting with double faced adhesive tape or adhesive tape.

The inventor urgently thinks a kind of " reflex housing of flat-panel screens module backlight " that can address the above problem originally in the spirit of positive invention, and several times research experiment is eventually to the invention of finishing these good common people of suffering from.

Summary of the invention

Fundamental purpose of the present invention is to provide a kind of flat-panel screens module reflex housing backlight, so that can simplify the program of lead fixed, and take in the lead that connects light source, stickability to double faced adhesive tape or adhesive tape when reducing fixing cord relies on, and because the position of lead fixed groove is arranged on reflex housing, so can improve the convenience of operating personnel when assembling, and improve module group render meritorious service rate backlight.

For reaching above-mentioned purpose, flat-panel screens of the present invention module reflex housing backlight is to cooperate at least one light source, this light source connects a lead at least, this reflex housing comprises that one has the reflection cover plate of a groove,, and the light of this light source is penetrated from this groove reflection in this groove in order to ccontaining this light source; And at least one lead fixed plate, be to have U-shaped, ㄩ shape or L shaped xsect and be connected on the sidewall edge of this reflection cover plate, in order to this lead of ccontaining this light source of connection; Wherein this lead is separated by the sidewall that should link to each other of this reflection cover plate mutually with this light source.

Flat-panel screens of the present invention module reflex housing backlight is preferably the lead fixed plate and integrates with the reflection cover plate, is more preferred from the integrally formed formation of punching press; Wherein reflect cover plate and have U-shaped, ㄩ shape or semicircular xsect, coat light source in order to the part, the reflection cover plate is preferably coating one reflection horizon or anti-UV layer towards the surface of this light source.And form between lead fixed plate and this reflection shroud sidewalls one can ccontaining this lead groove, this groove can be the continous way groove or catches on the discontinuous formula groove of this lead in order to locality.When the lead fixed plate was U-shaped, ㄩ shape, two parallel side of this U-shaped or ㄩ shape distance was enough to insert and put at least one lead.

Flat-panel screens of the present invention module reflex housing backlight is preferably and utilizes an adhesion to fix this lead, and when wherein this adhesion was between lead and lead fixed plate, this adhesion was preferably a double faced adhesive tape; And when this lead fixed plate when being L shaped, the peripheral preferable adhesive tape that utilizes of this lead is fixed on the lead fixed plate.
