Abstract

The utility model relates to a LBD information poor light board which is composed of four frames, two even light panel, two light-transmitting panel, a glistening panel and four LBD strip group, wherein the even light panel, the light-transmitting panel and the glistening are panel respectively inserted in the outer groove, internal groove and central groove of each frame, and the four LBD strip groups are inserted in the lamp groove of the both left and right side of two frames. The LBD strip panels can evenly irradiate light on the even light panel when electrifying and giving off light. The utility model has the advantages of saving energy, high degree of brightness and even radiation that is convenient to adjust the color of the light source, and separate or assembled using style as well as long useful time and saving the customer space.

Description

The LED information backlight

Technical field: the utility model relates to a kind of LED information backlight.

Background technology: at present, traditional advertising lamp box generally all is to adopt fluorescent lamp to do to have only refraction group plate in backlight and the lamp box.Its weak point is: 1, energy consumption height; 2, the brightness of case face is even inadequately; 3, be difficult to heat radiation, service life is short; 4, the thickness of casing and volume are bigger, and the cost height takies bigger space.

Summary of the invention: the purpose of this utility model provides a kind of LED information backlight, mainly is to solve to cut down the consumption of energy and problem such as brightness is even.The utility model is by frame 1, LED, even tabula rasa 2, pass tabula rasa 3 and reflector 4 formations, the both sides up and down of every frame 1 have a water jacket 5 respectively, one central channel 6 is arranged in the centre, on the both sides of central channel 6 inside groove 7 is arranged respectively, with on every inside groove 7 corresponding positions a light trough 8 is arranged all, the even tabula rasa 2 of both sides embed respectively every frame 1 water jacket 5 in, two pass tabula rasa 3 embed respectively every frame 1 inside groove 7 in, 4 of reflectors embed in the central channel 6 of each bar frame 1, all are inlaid with a LED group bar in each light trough 8.The outside on every frame both sides about in the of 1 has a link slot 9 respectively.

The beneficial effects of the utility model are: 1, energy-conservation and energy consumption is low, convenient other energy that use; 2, brightness is high and even, the convenient color of adjusting light source; 3, can use separately or in the mode of combination, to adapt to the instructions for use of various different users; 4, long service life, volume trifle save space, the convenient installation and transportation.

Description of drawings:

Fig. 1 is a profile schematic diagram of the present utility model.

Fig. 2 is an A-A generalized section of the present utility model.

Fig. 3 is a border structure schematic diagram of the present utility model.

Fig. 4 is that the utility model is used in combination view.

Fig. 5 is the utility model combined connecting structure B-B generalized section.

Among the figure: the 1st, frame, the 2nd, even tabula rasa, the 3rd passes tabula rasa, the 4th, reflector, the 5th, water jacket, the 6th, central channel, the 7th, inside groove, the 8th, light trough, the 9th, link slot, the 10th, connection sign indicating number, LED are light emitting diode group bars.

The specific embodiment:

The utility model will be further described below in conjunction with accompanying drawing:

Referring to Fig. 1～Fig. 4, the utility model is to pass tabula rasa 3, a reflector 4 and four LED group bars by the even tabula rasa of four edges frame 1, two 2, two to constitute, even tabula rasa 2, pass tabula rasa 3 and reflector 4 embeds respectively in water jacket 5, inside groove 7 and the central channel 6 of every frame 1, four LED group bars are embedded in respectively in the light trough 8 of two frames 1 of the left and right sides.LED group bar of the present utility model is when electrified light emitting, owing to pass the reflex of transmission, refraction, scattering and the reflector 4 of tabula rasa 3, the light uniform irradiation that LED group bar is sent is being spared on the tabula rasa 2 and is being made the plate face of even tabula rasa 2 evenly bright, at this moment, as long as the informative advertising propaganda picture of printing opacity is sticked on the frame 1 of the utility model both sides, just can show needed exploitation information in night.The utility model is owing to adopted LED group bar, thereby thin thickness, less, the low energy consumption of volume, thereby reach the saving energy, reduce the purpose that takes up room and increase the service life, the energy of convenient simultaneously other energy of use such as solar energy etc. etc., and the convenient color of adjusting light source easily, make the utility model show needed exploitation information, strengthen the exploitation effect with multiple color.

The utility model can use separately or in the mode of combination, when using in the mode of combination, just two adjacent LED information backlight can be fastenedly connected in link slot 9 the insides of frame 1 as long as will connect sign indicating number 10 inlay cards, thereby adapt to the instructions for use of various different users.

Claims
