Description
Technical field
The invention relates to a kind of light supply apparatus,, be applicable to the backlight liquid crystal display module particularly relevant for a kind of swapping type light source system.
Background technology
Because the fast development and the progress of Display Technique, the application of display universalness, particularly LCD more is widely used in various electronic products, for example computer screen and LCD TV.The light-source system of the employed backlight module of available liquid crystal display is fixed in the backlight module, mainly be the two ends that rubber cap bag (rubber cap) are enclosed within fluorescent tube, and make lead extend fluorescent tube, and then this light tube group is directly filled within the backboard of backlight module by this rubber cap bag.
Yet the mounting means of this kind light-source system has two shortcomings: the one, and when fluorescent tube damages and desire when changing, because light tube group is enclosed within the rubber cap bag and is fixed in the backboard, so that fluorescent tube more renews is difficult.Another is when lamp tube wire or the circuit board damage of fluorescent tube and cause light-source system can't normal operation the time, because this light-source system is filled in the inside in backboard, the maintenance personal dismantles difficult, and causing whole LCD to be scrapped can't use, and shortens the service life of this LCD.In view of this, necessary light-source system to existing backlight module improves.
Summary of the invention
One of the present invention purpose is to provide a kind of swapping type light source system, when light-source system is set at backlight module, makes the installation of the light-source system of display have more elasticity, to improve the convenience of manufacturing process.
Another purpose of the present invention is to provide a kind of swapping type light source system, when backlight module is keeped in repair, the dismounting of light-source system is more prone to, to improve the service life of display.
For reaching above-mentioned purpose, the invention provides a kind of swapping type light source system, be applicable to display unit, for example LCD or LCD TV, this swapping type light source system mainly comprises circuit of light sources plate, fixture and lead.The circuit of light sources plate is coupled to the housing and the backboard of this backlight module, and this circuit of light sources plate is provided with a plurality of light sources, first end and the second end.Fixture has a base, this base is provided with an alignment pin and clamping part, this alignment pin is accepted the first end of this circuit of light sources plate along first direction (X) and third direction (Z), that is this circuit of light sources plate being along mobile being restricted of first direction (X) and third direction (Z), and this clamping part is along the first end of second direction (Y) and this circuit of light sources plate of this third direction (Z) clamping.In other words, utilize this clamping part to limit this circuit of light sources plate moving along second direction (Y) and third direction (Z).
Therefore when this circuit of light sources plate and this fixture were bonded together, this circuit of light sources plate was subject to first direction (X), second direction (Y) and third direction (Z), so firm this swapping type light source system of combination formation.
This backlight module mainly comprises circuit of light sources plate, fixture, backboard and housing, and this backboard is in order to guide this circuit of light sources plate, and this housing is in order to carry this circuit of light sources plate.This backboard is provided with guiding structural, this guiding structural comprises a guide posts, a guiding side and the stop portion that is connected in this guiding side one side, this guide posts and this guiding side stagger mutually and form a guiding opening, enter this housing in order to the second end of guiding this circuit of light sources plate along this guiding opening.
When this swapping type light source system is inserted spatial accommodation between this backboard and this housing, the snapping portion on the base of being arranged at fastens the snapping opening of this backboard, and to utilize second slit on the base to make this snapping portion flexibly be buckled in this snapping opening along first direction (X).In addition, second concave domain of first side plate of this fixture is engaged in the groove of this backboard, further to fix this swapping type light source system in this backboard along the opposite direction of first direction (X).Secondly the latch of this fixture extends along this first direction (X), so that this fixture is plugged in the socket of this shell block.
Therefore swapping type light source system of the present invention utilizes snapping portion, second concave domain and latch to be engaged in snapping opening, groove and socket respectively, make swapping type light source system closely be connected with this backboard and with this housing respectively, firmly fixing this fixture, and avoid light to leak by the breach space between this backboard and this housing in backlight module.
Swapping type light source system of the present invention compared to existing fixed system install and maintenance on have more elasticity, and the dismounting of light-source system is more prone to, and effectively improves the service life of display.
For foregoing of the present invention can be become apparent, preferred embodiment cited below particularly, and cooperate appended graphicly, be described in detail below:
