Description

A kind of simple and easy LED projection arrangement
[technical field]
The utility model relates to a kind of projection arrangement, refers in particular to a kind of simple and easy LED projection arrangement.
[background technology]
Advertising signboard in the past or LOGO sign all are that the pattern or the literal that adopt traditional lamp box to light back irradiation tank surface present pattern, and there are shortcomings such as energy consumption is high, pattern is prone to come off, fade, volume is big in this structure.Light emitting diode (LED) is a kind of semiconductor solid luminescence device; It is to utilize the solid semiconductor wafer as luminescent material; When two ends add forward voltage; Charge carrier in the semiconductor takes place compoundly to cause photo emissions and produce light, is the most popular now light source technology, and led light source has plurality of advantages such as energy-saving and environmental protection, long service life, response time are fast.The LED dot matrix display board of replacement conventional ads lamp box, LOGO sign is seen everywhere now; The energy consumption of LED advertisement display board is low, bright in luster, volume is little, long service life; But LED advertisement display board owing to adopted LED as pixel luminous point light source; Therefore a big LED advertisement display board needs thousands of LEDs, and the LED price is very expensive with respect to conventional light source, simultaneously because its numerous LED need be fixed on the display board; Need a large amount of man-hours; This just makes its cost of manufacturing process rise, and has caused the present high price of LED advertisement display board at last, so people thirst for obtaining a kind of product of alternative LED advertisement display board with low cost always.
[utility model content]
To complex structure, the cost high-technology defective that LED advertisement display board in the prior art exists, the purpose of the utility model is to provide a kind of product of alternative LED billboard simple in structure, with low cost.
In order to reach above-mentioned technical purpose; The technical scheme that the utility model is taked is a kind of simple and easy LED projection arrangement; Comprise housing, be installed in the interior led light source of housing, be arranged on the preceding lens combination of led light source; And be arranged on the housing light-emitting window over against led light source and lens combination; It is characterized in that: said led light source comprises substrate, is formed at the crystal bonding area on the substrate, the packing colloid that is fixed on the plurality of LEDs chip in the crystal bonding area and is filled in covering plurality of LEDs chip in the crystal bonding area, and said crystal bonding area is prefabricated patterned crystal bonding area.
Preferably, said patterned crystal bonding area is various pattern modellings.
Preferably, said patterned crystal bonding area is various text styles.
Preferably, said light-emitting window is equipped with a light transmission piece.
Preferably, said packing colloid is a fluorescent colloid.
Preferably, said fluorescent colloid is the yellow fluorescence colloid, and said led chip is a blue-light LED chip.
Preferably, said led chip is ruddiness, green glow or blue-light LED chip.
Preferably, said led chip is a RGB three-primary color LED chipset.
The simple and easy LED projection arrangement of the utility model has adopted graphical integrated encapsulated LED module; Its crystal bonding area is arranged to various patterns or text style, and the luminous intensity distribution of lighting back scioptics group can directly demonstrate the pattern or the literal of expection on body of wall or advertising page.The utility model projection arrangement can go out various patterns or text style by direct irradiation; LED advertisement board structure with respect to traditional is simple, with low cost; And installation and debugging all are easy to; Volume is littler, and will be the substituted type product that traditional large LED shows signboard future, can serve as general simple and easy display screen or LOGO display card.

[embodiment]
Technical scheme for further detailed elaboration the utility model is elaborated below in conjunction with accompanying drawing.
Like Fig. 1, Fig. 2, Fig. 3, shown in Figure 4; The utility model discloses a kind of simple and easy LED projection arrangement; Comprise housing 2, be installed in led light source 1 in the housing 2, be arranged on the lens combination 3 before the led light source 1; And be arranged on the housing 2 light-emitting window 4 over against led light source 1 and lens combination 3; Said light-emitting window 4 is equipped with a light transmission piece 5, and said led light source 1 comprises substrate 11, is formed at the crystal bonding area 12 on the substrate 11, the packing colloid 14 that is fixed on the plurality of LEDs chip 13 in the crystal bonding area 12 and is filled in covering plurality of LEDs chip 13 in the crystal bonding area 12, and said crystal bonding area 12 is prefabricated patterned crystal bonding area.
The described patterned crystal bonding area 12 of the utility model is various pattern modellings or text style; Like crystal bonding area 12 can be various pictorial trademarks, Business Name, advertising language, various sign, cartoon pattern etc., and crystal bonding area 12 shown in Figure 4 is the moulding of " A " font.
As the further improvement of the utility model, said packing colloid 14 can be a fluorescent colloid; Said fluorescent colloid can be selected the yellow fluorescent glue body for use, and said led chip 13 can be selected blue-light LED chip for use.
