Abstract
The utility model relates to a two-pole body scatting light source board. The utility model is proposed for providing the two-pole body scatting light source board with simple processing, easy fabrication, low cost, high production quality, and good scattering effect. The utility model is composed of a light conducting board seat, a circuit board set, a light conducting board and a diffusion sheet. Putting edges on both sides of the light conducting board seat are provided with positioning holes and positioning columns. A longitudinal circuit board and a transversal circuit board which form the circuit board set are respectively provided with a terminal, a through hole and a plurality of light emitting diode bodies. The light conducting board is ground glass whose upper side surface and bottom surface are provided with mist patterns witch are once formed, and both sides of the frosted glass are jointing flanges which are provided with through holes which are sheathed on positioning columns. The diffusion sheet is not transparent, and are stuck and covered on the upper surface of the light conducting board.
Description
The utility model belongs to optical element, particularly a kind of diode scattered light source plate.
All be provided with the function display window on present any household appliances, how operate and use to inform the user.For making things convenient for the user, the scattered light source plate of being made up of leaded light panel seat, circuit board, light guide plate and diffusion sheet is set in the function display window of household appliances usually.The positive and negative surface of the light guide plate of this scattered light source plate is smooth transparent area.For improving its dispersion effect, process the strip hair line once more on the light guide plate surface usually.Promptly light guide plate is carried out secondary processing, has not only increased production cost of products, and in process because of the generation of soft flocks foreign material, influence product quality.
The purpose of this utility model provides a kind of diode scattered light source plate simple, easily manufactured, that cost is low, product quality is high, dispersion effect is good of processing.
The utility model is made up of leaded light panel seat, circuit board group, light guide plate and diffusion sheet, and leaded light panel seat both sides and bottom are provided with the storing edge, and is provided with pilot hole and reference column on both sides storing edge; Circuit board group is made up of the vertical, horizontal circuit board, and the longitudinal circuit plate is provided with plug-in mounting and is sleeved on terminal down and through hole on leaded light panel seat pilot hole and the reference column; Transverse circuit plate medial surface is provided with a plurality of light-emittingdiodes; Light guide plate is that upper and lower surface is provided with the vaporific colored frosted glass that picks, and its both sides are to be provided with the joint edge of a wing that is sleeved on through hole on the reference column; Diffusion sheet is opaque shape, and pastes at the light guide plate upper surface.
Because the utility model is made up of leaded light panel seat, circuit board group, light guide plate and diffusion sheet, leaded light panel seat both sides are put edge and are provided with pilot hole and reference column; Be respectively equipped with terminal, through hole and a plurality of light-emittingdiode on the vertical, horizontal circuit board of built-up circuit plate group; Light guide plate is that upper and lower surface is provided with that once-forming is vaporific to pick colored frosted glass, and its both sides are to be provided with the joint edge of a wing that is sleeved on through hole on the reference column; Diffusion sheet is opaque shape, and pastes at the light guide plate upper surface.During manufacturing, need not to carry out secondary processing, process simple, easily manufactured, cost is low, product quality is high; During use,, improve the dispersion effect of two utmost point luminophor light sources in light guide plate, thereby reach the purpose of this utility model with the vaporific refraction action that picks colored upper and lower surface, diffusion sheet and leaded light panel seat of light guide plate.

Fig. 2, be the utility model decomposition texture schematic isometric.
Fig. 3, be the utility model structural representation sectional view.
Fig. 4, be the local structure for amplifying schematic isometric of A portion among Fig. 2.
Fig. 5, be the utility model user mode synoptic diagram.
Below in conjunction with accompanying drawing the utility model is further elaborated.
As Fig. 1, Fig. 2, shown in Figure 3, the utility model is made up of leaded light panel seat 1, circuit board group 2, light guide plate 3 and diffusion sheet 4, and leaded light panel seat 1 both sides and bottom are respectively equipped with puts edge 11,12, and is provided with pilot hole 13 and reference column 14 on both sides storing edge 11; Circuit board group 2 is made up of vertical, horizontal circuit board 21,22, and longitudinal circuit plate 21 is provided with plug-in mounting and is sleeved on terminal down 211 and through hole 212 on leaded light panel seat 1 pilot hole 13 and the reference column 14; Transverse circuit plate 22 medial surfaces are provided with a plurality of light-emittingdiodes 221, and at light-emittingdiode 221 surface-coated silastics 222; Light guide plate 3 is provided with the vaporific colored frosted glass that picks for upper and lower surperficial 31,32, its both sides are to be provided with the joint edge of a wing 34 that is sleeved on through hole 33 on the reference column 14, and as shown in Figure 4, order engages the edge of a wing 34 and is connected with light guide plate 3 bodies with wedge-like vertical plane 35, makes rapid scattering of pointolite and refraction; Light-emittingdiode 221 opposite flanks 36 are beaten bright for the continuous circular arc waveform on light guide plate 3 and the transverse circuit plate 22, and make each circular arc 361 forgive a light-emittingdiode 221; Diffusion sheet 4 is opaque shape, and pastes the upper surface 31 in light guide plate 3.
During use, as shown in Figure 5, light guide plate 3 is gone in light A, the B that light-emittingdiode 221 on the transverse circuit plate 22 sends, C and D direct projection, light A, C, D are dispersion shape after the vaporific refraction of picking colored upper surface 31, lower surface 32, diffusion sheet 4 and leaded light panel seat 1 of light guide plate 3, light B is directed to the top of light guide plate 3, thus the light that makes light-emittingdiode 22 equably scattering in light guide plate 3.
