Abstract

The utility model discloses a solar power safety lamp for automobiles used for illumination of bicycles and automobiles. When a light source is existed, a solar energy plate (Solar) can receive light energy and convert the light energy into electrical energy. Thus, a battery can be charged through the control of an electric circuit board apparatus. When the light source is not existed, the solar energy plate (Solar) can stop absorbing the light energy. Thus, the rechargeable battery can automatically discharge the electrical energy through the control of the circuit board, and then a diode LED is in luminescent state. The solar power safety lamp comprises a shell, a transparent upper cover on the top pf the shell, a transparent panel at the front, and the solar energy plate and the circuit board which are arranged in shell.

As Fig. 1～shown in Figure 3, the vehicle that the utility model provides solar energy night safe lamp, mainly comprise a solar energy safety lamp housing (1), one transparent upper cover (11), and front side cover cap one transparent panel (13) of housing (1), be provided with ventilation heating panel (141) at housing (1) back (14) and be provided with switch (16) in housing (1) side in addition with pilot hole seat (142), therefore be embedded with nut (143) at pilot hole seat (142), can attachment screw this safety lamp and bicycle or vehicle be locked together.

Be provided with solar panels (12) in housing (1) inside, a rechargeable battery E, a pcb equipment (15) that is connected with switch (16), solar panels (12) and battery E, and the battery tray that can put described battery E is when light source exists, solar panels (12) receive luminous energy and convert thereof into electric energy by transparent upper cover (11), via circuit board arrangement (15) control and make battery E charging, at this moment, diode (LED) is and extinguishes state; When light source did not exist, solar panels (12) stopped to absorb luminous energy again, and rechargeable battery is emitted electric energy automatically and made diode (LED) luminous through circuit board arrangement (15) control.

As Fig. 4～shown in Figure 10, it is a vehicle of the present utility model circuit with solar energy night safe lamp, this circuit by charging circuit (accompanying drawing 5), force failure of oscillations circuit (accompanying drawing 6), control circuit (accompanying drawing 7), oscillating circuit (accompanying drawing 8), resonant circuit (accompanying drawing 9), booster circuit (accompanying drawing 10) to be formed.

By described charging circuit by day or light source when existing, absorb luminous energy and produce voltage by solar panels (12), electric current via diode S1 to battery E charging (please refer to accompanying drawing 5); Mat forces failure of oscillations circuit (as shown in Figure 6) and produces voltage by solar panels (12) again, this voltage provides the voltage that can make transistor T 2 conductings through resistance R 3 to transistor T 2, transistor T 2 conductings make transistor T 1 base potential be lower than conducting voltage and end, so the time LED be and extinguish state.

Moreover, the described control circuit of mat (as shown in Figure 7), when light source does not exist or light source intensity when dying down, the voltage of solar panels (12) is step-down thereupon also, internal resistance descends, add that for making resistance R 3 obtain higher voltage resistance R 4 makes the voltage of solar panels (12) when being lower than the required voltage of transistor T 2, can replenish, make that the oscillating circuit in this circuit arrangement can just begin to light diode (LED) when light intensity is very weak by resistance R 4; The luminous system of wherein said diode (LED) energy is by due to oscillating circuit (as accompanying drawing 8), resonant circuit (as accompanying drawing 9), the booster circuit (as accompanying drawing 10).

In the described oscillating circuit (with reference to figure 8): voltage makes transistor T 1 conducting through resistance R 1 and resistance R 2, the electric current of resistance R 1 flows to emitter through the collector electrode of transistor T 1 after the conducting, and the decline of resistance R 1 voltage and resistance R 2 no enough voltages are provided to transistor T 1, being directed at transistor T 1 ends, transistor T 1 by the time, voltage makes transistor T 1 go conducting and vibrating again through resistance R 1 and resistance R 2 again.

Described resonant circuit (cooperating with reference to figure 9) is: when transistor T 1 conducting, resistance R 1 voltage descends and makes transistor T 3 conductings, electric current flows to collector electrode by the emitter of transistor T 3, the inductance L 1 of also flowing through, capacitor C 1 obtains positive voltage by transistor T 3 collector electrodes, make another utmost point respond to negative voltage, this makes transistor T 1 stop conducting at once; Transistor T 1 stop conducting rises resistance R 1 voltage, make transistor T 3 stop conductings, the contrary electrodynamic type that the collector electrode of transistor T 3 is subjected to inductance L 1 at once is sensed as negative voltage, make the another side of capacitor C 1 respond to generation one positive voltage again, and make transistor T 1 conducting generation resonance again, to play province's electro ultrafiltration.
