Abstract
The utility model discloses a billboard powered by a luminescent diode, comprising a light guide panel 1, a glistening film2, luminescent diodes3 and a back cover board5, wherein the light guide panel 1 is provided with a display space on the surface to display images; the non-display space on the light guide panel 1 surface is covered with the glistening film2; the glistening side of the glistening film2 faces the inner side of the light guide panel 1; the back cover board5 covers the back of the light guide panel1; one side edge of the light guide panel1 is provided with a plurality of luminescent diodes3 which are fixed on a printed circuit board6; the printed circuit board6 is provided with a cushion7 at the back to stop the printed circuit board6 and the luminescent diodes3 from dropping due to shake. The utility model is characterized in that the back of the light guide panel1 is of a bevel which uptilts from the side which is near the luminescent diodes3; the bevel is covered with the glistening film2 whose glistening side faces the inner side of the light guide panel1; a strengthening ledger plate is added between the back cover board5 and the glistening film2. since the glistening film2 on the back of the light guide panel 1 is slanting arranged, the beams from the display spaces8 are of even brightness, thus improving the display effect of the images; since only one edge of the light guide panel1 is provided with luminescent diodes, which are small in number, thus reducing making cost and electric power consumption.
Description
Technical field
It is the billboard of light source with the light emitting diode that the utility model relates to a kind of.
Background technology
Light emitting diode (LED) material development in recent years is rapid, and the normal light intensity after the single-chip package of the superhigh brightness LED (LED) of red, green, blue, Huang, white has all reached several CD (candela), even tens CD.This has created condition for the application of LED.At present, various fixedly direction boards (comprising place name signs such as street guideboard, doorplate, traffic mark board, Fire Alarm, the various sign boards of airport, station, harbour etc.) are passive display mode, can't play effect at night under the dark surrounds.Also have and take long-afterglow fluorescent to show, but shortcomings such as brightness is low, effectively the demonstration time is short, serviceable life is short are arranged.For this reason, someone has invented a kind of is the billboard of the active display type of light emitting source with the light emitting diode, is CN1388494A as publication number, and application number is 02123761.1 patent of invention, this patented claim has solved the problem of above-mentioned existence, but,, the consumption of light emitting diode is strengthened because of its light emitting diode is that two sides distribute at least, virtually, manufacturing cost is improved, and in use, power consumption is relatively large.
The utility model content
The purpose of this utility model is to overcome the problem that above-mentioned patented claim exists, and provide a kind of low cost of manufacture, power consumption little be the billboard of light source with the light-emitting diodes.
The utility model includes light guide plate, reflective membrane, light emitting diode, back of the body cover plate, wherein, the non-display area on light guide plate surface pastes with reflective membrane, the reflective surface of reflective membrane is towards light guide plate inside, back of the body cover plate covers the back side in light guide plate, one side of light guide plate is provided with several light emitting diodes, this light emitting diode is fixed on the printed circuit board (PCB), and the back side of printed circuit board (PCB) is provided with cushion, to prevent that printed circuit board (PCB) and light emitting diode from being come off by vibrations, the back side of light guide plate is the inclined-plane, and this inclined-plane is inclined upwardly from the side direction opposite side that light emitting diode is set, this inclined-plane is provided with reflective membrane, the reflective surface of this reflective membrane is towards light guide plate inside, and back of the body cover plate covers the back in reflective membrane, in addition, but back of the body cover plate also level covers, and can fill out between itself and the reflective membrane and establish the reinforcement fixed head.
The utility model reaches unanimity the light intensity that penetrates from each viewing area and has improved display effect because the reflective membrane of light guide plate back is oblique setting, and the distance of its end-to-end distance viewing area is short than head end.Be one-sided setting owing to light emitting diode again, consumption is less, the power consumption when having reduced manufacturing cost and use.
