Embodiment:

The present embodiment system architecture is provided with the control circuit that is made of central processing unit and timer and the little processing of CPU as shown in Figure 1; Adopt silicon solar cell, the inverter that battery pack, charger is set simultaneously and produces the light emitting source working power.

Referring to Fig. 1, Fig. 2, in the present embodiment, in lamp box 1, be light source with the high brightness LED, this high brightness LED comprises that red, green, blue tricolor pipe LED is red, LED is green and LED is blue, and the red, green, blue tricolor pipe carries out locational arranging according to advertising design in lamp box 1.

In concrete the enforcement, it is the LED of the big argument of high brightness that lamp box 1 adopts high-strength PVC material, high brightness LED, along with the semiconductor light emitting technology is progressive greatly, the luminous intensity of LED luminotron is improving constantly, common LED luminous intensity is several mcd to tens mcd, and the LED of high brightness develops into a hundreds of mcd to thousands of mcd.

Light emitting source in the native system adopts the light emitting diode of super brightness, glow color is respectively red, green, blue, also can comprises white, and diameter is Φ 5 big diffusion transparent resin encapsulation, crucial technology Allncap in addition on CaAs, other has 120 ° of very large emission angle.Anti-electrostatic discharging: material is that Allncap is 2kV.

Absolute rating: reverse voltage V _R=5V, forward current I _F=50mA (T _Amb≤ 85 ℃), surge forward current I _FSN=1A (t _p≤ 10s), power p _r=135mW, 125 ℃ of junction temperatures, working range are-40 ℃-100 ℃.

Fig. 2 illustrates, in order to work safely, must series limiting resistor R1, R2 in led circuit, R3, and current-limiting resistance can be calculated as follows: R=(Vcc-Vfxn)/I _F

Referring to Fig. 3, the central processing unit in the present embodiment mainly is that program control flash of light integrated circuit is arranged, and it is big to have integrated level, and function is strong, and volume is little.The CPU integrated circuit adopts 16 pin dual inline type plastic package, and inside is integrated, and style controller, timing pulse generator, oscillator, code translator, expansion switch, style storer and driving circuit and timing circuit are formed.Adopt Schmidt trigger, external resistor and capacitor component R9 and C1, internal oscillator produce needed clock frequency, octal representation device and 3 external style controllers.Select various style controls respectively to organize reading of unit by the sequential that sequential decoder produces, Q1, Q2, Q3 output are used for controlling thyristor VS1, VS2, VS3 after driving circuit amplifies, and also directly driving LED is luminous.Export by Q1-Q3, can make light emitting source carry out various combination, send the light source of seven coloured silks, conduction angle by the control thyristor, can change the light emitting source power, produce different combined effects, timer function is arranged in cpu controller, by coding can be set the different time, finish regularly on of light emitting source.
