Abstract
A focused LED display board consists of light emitting diodes, circuit boards, a light guiding board, packing boards, and transparent panels. The circuit boards with LEDs are arranged on the both ends of the light guidinog board and are packed with the packing boards. The transparent panels cover on the both sides of the light guiding board. The display board reduces power consumption extremely and is compact due to taking focusing LEDs as light sources. It can be very thin in thickness and used in various places widely.
Description
Technical field
A kind of LED photoelectric focusing display sign relates to the improvement of lighting display card.
Background technology
Now the general photoelectric display board that uses in market all adopts bulb or light pipe to do light source, in case bulb or light pipe extinguish, the display board that shows is joined by institute just can't be to people to indicate.More existing recently producers adopt the LED light emitting diode to do light source, because under normal circumstances, light emitting diode (LED) life-span is long, but single diode successively-ignited 50,000 hour, if do the light source of display board with a pile light emitting diode,, still can have the part light source that display board is lighted even if the part light emitting diode extinguishes.But because the light that diode sends is still pointolite, its brightness meeting differs with the quality light and shade of each light emitting diode, can see flickering effect from display board.
Summary of the invention
The purpose of this invention is to provide a kind of LED focusing display sign, both extracted the long-lived advantage of light emitting diode, simultaneously the pointolite of diode is become poly-irradiating light beam, make on the display board that each pattern or the photochromic unanimity of font are even.
The said LED photoelectric focusing display sign of the present invention is made up of light emitting diode 1, wiring board 2, leaded light frid 3, shrouding 4, and wherein light emitting diode 1 is contained on the wiring board 2, and the wiring board 2 that has light emitting diode 1 embeds the two ends of leaded light frid 3.For the light of each light emitting diode 1 is efficiently put together, the present invention makes leaded light frid 3 usefulness transparent plastics, be carved with in regular turn on 3 of leaded light frids that big centre, two is little, low leaded light groove 6 between the senior middle school of two ends, make the ray refractive index of light emitting diode 1 be equal to or greater than 90 °.
Description of drawings
Fig. 1 is a LED photoelectric focusing display sign structural representation of the present invention;
Fig. 2 is a schematic side view of loading onto leaded light frid 3 behind the light emitting diode;
Fig. 3 is equipped with the LED photoelectric focusing display sign structural representation that indicates road sign note panel;
Fig. 4 is a kind of LED photoelectric focusing display sign schematic appearance of shape triangular in shape;
Fig. 5 is the LED photoelectric focusing display sign schematic appearance of pillar shape.
As Fig. 1, shown in Figure 3, the said LED photoelectric focusing display sign of the present invention is made up of light emitting diode 1, wiring board 2, leaded light frid 3, shrouding 4, wherein the wiring board 2 that has light emitting diode 1 is embedded the two ends of leaded light frid 3, shrouding 4 is fastened on the outside of wiring board 2, the two sides that the transparency panel 5 that is painted with character pattern is enclosed in leaded light frid 3 is formed again.
For being assembled, the pointolite of each light emitting diode is photochromic uniform light beam, as shown in Figure 2, the said leaded light frid 3 usefulness transparent plastics of the present invention are made, be carved with in regular turn on the plate face that big centre, two is little, low leaded light groove 6 between the senior middle school of two ends, as long as make the ray refractive index of light emitting diode 1 be equal to or greater than 90 °, promptly can concentrate the faint light that each diode 1 distributed to be photochromic uniform light beam.
The LED focusing display sign that adopts the said structure of the present invention to make, because the effect by leaded light frid 3 of the pointolite of each diode 1 is formed photochromic uniform light beam, as long as be equipped with the transparency panel 5 that is painted with character pattern, just can make as Fig. 3, Fig. 4, photochromic uniform direction board, advertisement display board shown in Figure 5, its power consumption can lack more than 50% than light pipe, bulb.Because light emitting diode 1 volume own is just very little, and in the present invention, only adopt up and down to the dress formula, the consumption of light emitting diode 1 seldom, circuit is simple, therefore can accomplish display board very little, very thin; Because the life-span of diode 1 is long, photochromic bright and even, the color that can choose combination is a lot of again in addition, comprise red, green, yellow, blue, white and amber etc., guideboard, lamp box or the signboard of different shape can be made,, various places can be widely used in as Fig. 3, Fig. 4, shown in Figure 5.
Claims (2)
1, a kind of LED photoelectric focusing display sign, form by light emitting diode (1), wiring board (2), leaded light frid (3), shrouding (4), it is characterized in that the wiring board (2) that has said light emitting diode (1) is embedded the two ends of leaded light frid (3), shrouding (4) is fastened on the outside of wiring board (2), the two sides that the transparency panel (5) that is painted with character pattern is enclosed in leaded light frid (3) is formed again.
2, according to the said LED photoelectric focusing display sign of claim 1, it is characterized in that adopting transparent plastic to make at said leaded light frid (3), be carved with in regular turn on the plate face that big centre, two is little, low leaded light groove (6) between the senior middle school of two ends, make the ray refractive index of light emitting diode (1) be equal to or greater than 90%.
