Description of drawings
Be elaborated below in conjunction with the drawings and specific embodiments the utility model:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the principle schematic that is electrically connected of the present utility model;
Fig. 3 is the arrangement architecture schematic diagram of Led luminescence chip of the present utility model;
Fig. 4 is RGB three mixture of colours schematic diagrames.
The specific embodiment
As Figure 1-3, a kind of Led lamp comprises housing 110, circuit board 120 and light diffusing sheet 130.
Control module 140 is connected with Led driver module 150.
The utility model utilizes RGB three primary colours composition principle, control electric current or the voltage swing of RGB Led respectively, produce the dreamlike backlight of various different colours thereby realize mixing, electric current or the voltage swing that can change RGB Led according to the different time that uses and occasion realized versicolor backlight and purpose of energy saving simultaneously.
According to three primary colours brightness-formula Y=0.30R+0.59G+0.11B, Led luminescence chip group 160 comprises ruddiness Led luminescence chip 161, blue light Led luminescence chip 162 and two green glow Led luminescence chips 163 that matrix is arranged, wherein, Y represents white brightness, R, G, B represent red, green, blue three looks respectively, as seen will obtain white, can with 0.3 red, 0.59 green, 0.11 blue the mixing obtain white, same, the red, green, blue of adjusting different proportion respectively can obtain more color.
If with above-mentioned three kinds of Led luminescence chips simply array packages can not make the color of light of three kinds of Led be mixed into white light well so so together.RGB three mixture of colours schematic diagrames as shown in Figure 4, having only zone line is three kinds of zones that color has, so have only zone line to be only white light, other zones are not white lights.The light energy that three kinds of chips of RGB send mainly is distributed within the certain angle centered by light source optical axis, so after the light that is sent by different chips on the diverse location will propagate certain distance, just overlapping and then colour mixture may take place.Even yet after propagating certain distance, still have only the central area white light just to occur, that is to say that the zone beyond the central area is not still mixed, and the bigger light of dispersion angle causes then luminous efficiency to reduce through propagating the back away from the center.
And consider the ratio height of green demand, therefore, green glow Led luminescence chip 163 is two.
Particularly, as Fig. 2 and shown in Figure 3, ruddiness Led luminescence chip 161, blue light Led luminescence chip 162 and two green glow Led luminescence chips 163 all are connected with Led driver module 150, and two green glow Led luminescence chip 163 diagonal angle settings.
Be understandable that Led luminescence chip group 160 can be many groups, organize Led luminescence chip group 160 matrixes more and arrange.
As shown in Figure 1, light diffusing sheet 130 is located at the top of circuit board 120, namely is installed in the opening part of housing 110.
| LED spacing mm | 12 | 15 | 18 | 22 |
| Light mixing distance mm | ≥14.5 | ≥19 | ≥23.5 | ≥28 |
Table 1
Namely when the spacing of ruddiness Led luminescence chip 161, blue light Led luminescence chip 162 and green glow Led luminescence chip 163 is 12mm, the minimum light mixing distance between itself and the light diffusing sheet 130 is 14.5mm.
When the spacing of ruddiness Led luminescence chip 161, blue light Led luminescence chip 162 and green glow Led luminescence chip 163 was 15mm, the minimum light mixing distance between itself and the light diffusing sheet 130 was 19mm.
When the spacing of ruddiness Led luminescence chip 161, blue light Led luminescence chip 162 and green glow Led luminescence chip 163 was 18mm, the minimum light mixing distance between itself and the light diffusing sheet 130 was 23.5mm.
When the spacing of ruddiness Led luminescence chip 161, blue light Led luminescence chip 162 and green glow Led luminescence chip 163 is 22mm, the minimum light mixing distance 28mm between itself and the light diffusing sheet 130.
What certainly can understand is that the spacing of ruddiness Led luminescence chip 161, blue light Led luminescence chip 162 and green glow Led luminescence chip 163 is for being not limited to 12mm, 15mm, 18mm or 22mm
Photochromic control principle of the present utility model: by control module 140 control Led driver modules 150, and then voltage or the electric current of control ruddiness Led luminescence chip 161, blue light Led luminescence chip 162 and green glow Led luminescence chip 163, and by light diffusing sheet 130 light of each Led luminescence chip is carried out mixed light, obtain the light of different colours.
The RGB three look Led luminescence chips that present embodiment is selected for use are respectively:
1SC3020B13F0CC01 SMD 3020 blue lights
1SC3020G73F0CC01 SMD 3020 emerald green light
1SC3020V24I0CC01 SMD 3020 ruddiness
Adopt each equidistant matrix form of row-row, column-Lie to arrange, line space is 22mm, column pitch 18mm, light mixing distance is 28mm, power supply is selected the 24V dc source for use, can directly buy, the Led drive circuit has been selected constant current source driving circuit for use, and wherein the total current of R is 0-100 milliampere (adjustable), and the total current of G is 0-100 milliampere (adjustable), the total current of B is 0-100 milliampere (adjustable), can reach the effect of mixing out different colours light by the electric current of regulating each Led luminescence chip like this.
According to the principle of three primary colours, the light of different colours can be obtained by RGB three looks, and main color is followed following principle:
Red+green+blueness=white
Red+green=yellow
Green+blueness=cyan
Red+blue=magenta
Redness+cyan=white
Green+magenta=white
Blue+yellow=white
