Description
Technical field
This utility model relates to a kind of backlight module.
Background technology
Liquid crystal indicator is the display using liquid crystal to provide image, it is generally made up of liquid crystal panel, backlight module, relevant digital circuit and power supply etc., for light leakage, LED lamp bar in backlight module presses close to liquid crystal panel, liquid crystal panel is easy to damage the LED lamp bead in LED lamp bar by pressure, affect the luminescence of LED lamp bead, thus affect the quality of backlight effect and liquid crystal indicator.
Utility model content
In order to overcome the deficiencies in the prior art, this utility model provides a kind of backlight module, and simple in construction, LED lamp bar is provided with projection, is possible to prevent LED lamp bead to be squeezed.
This utility model solves the technical scheme that its technical problem is used:
A kind of backlight module, including radiating block and LED lamp bar, described LED lamp bar is provided with LED lamp bead, and described radiating block is provided with the groove matched with described LED lamp bar, and described LED lamp bar is provided with the end face projection higher than LED lamp bead.
Further, described radiating block is provided with heat sink, and described heat sink is aluminium alloy, and the described heat sink back side is provided with a plurality of heat radiation raised line.
Further, the described heat sink back side is provided with conflict raised line, and described conflict raised line is located at the top edge of heat sink, and the end face of described conflict raised line liquid crystal panel dorsad is higher than heat radiation raised line.
Further, described groove is hook, and each corner of described groove is 90 °.
Further, described groove, heat radiation raised line and conflict raised line are formed by Milling Machining.
The beneficial effects of the utility model are: LED lamp bar is inserted the groove in radiating block; LED lamp bar is stabilized on radiating block; the LED lamp bar upper surface projection higher than LED; play the function of protection LED lamp bead; prevent LED lamp bar to be squeezed, thus the quality of luminous effect, backlight effect and the liquid crystal indicator of LED lamp bead has been effectively ensured.
Accompanying drawing explanation
With embodiment, this utility model is further illustrated below in conjunction with the accompanying drawings.
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
With reference to Fig. 1, a kind of backlight module, including radiating block 1 and LED lamp bar 2, LED lamp bar 2 is provided with LED lamp bead 22, and radiating block 1 is provided with the groove 11 matched with LED lamp bar 2, and LED lamp bar 2 is provided with the end face projection 21 higher than LED lamp bead 22.
LED lamp bar 2 is inserted the groove 11 in radiating block 1; LED lamp bar 2 is stabilized on radiating block 1; LED lamp bar 2 upper surface projection 21 higher than LED; play the function of protection LED lamp bead 22; prevent LED lamp bar to be squeezed, thus the quality of luminous effect, backlight effect and the liquid crystal indicator of LED lamp bead 22 has been effectively ensured.
In the present embodiment, it is preferred that radiating block 1 is provided with heat sink 12, and heat sink 12 is aluminium alloy, lightweight, perfect heat-dissipating, and heat sink 12 back side is provided with a plurality of heat radiation raised line 121, can preferably dispel the heat.
In the present embodiment, it is preferred that heat sink 12 back side is provided with conflict raised line 122, conflict raised line 122 is located at the top edge of heat sink 12, and the end face of conflict raised line 122 liquid crystal panel dorsad is higher than heat radiation raised line 121, and conflict raised line 122 offsets with heat-dissipating casing, form certain heat-dissipating space, be conducive to heat radiation.
In the present embodiment, it is preferred that groove 11 is in hook, and each corner of groove 11 is 90 °, mates with LED lamp bar 2, is stabilized on groove 11.
In the present embodiment, it is preferred that groove 11, heat radiation raised line 121 and conflict raised line 122 are formed by Milling Machining, and processing is simple, it is simple to batch production.
The above, better embodiment the most of the present utility model, but this utility model is not limited to above-described embodiment, as long as it reaches technique effect of the present utility model with any same or similar means, within all should falling into protection domain of the present utility model.
