Description
Technical field:
The utility model relates to a kind of light-emitting device, and especially a kind of is the energy and the luminous device that glimmers with solar energy.
Background technology:
Light-emitting device (such as guardrail ornament lamp, road indicating lamp etc.) all was the energy with the dry cell mostly in the past, use dry cell not only to waste energy, and old and useless battery had also become one of tellurian several big public hazards for the pollution that environment caused; Particularly, use the light-emitting device of battery also light-sensitive element and correspondent control circuits must be set, its circuit structure complexity for only needing noctilucent device; For this reason, the self-luminescent material that can replace battery becomes the first-selection of many occasions.Self-luminescent material is to be operation principle to absorb luminous energy daytime, to discharge luminous energy night, and material itself is a light-emitting component, has solved light-emitting device and has used a series of problems that battery brought.But the shortcoming of self-luminescent material maximum is to continue night luminously, and it is luminous to glimmer, therefore, need be for some by the luminous place that reaches the caution purpose of glimmering, the use of self-luminescent material just is restricted.Therefore, up to the present, all light-emitting devices with flashing function all are to be its power supply with battery or civil power.
Summary of the invention:
The purpose of this utility model is in order to solve the existing in prior technology technical problem, and providing a kind of is the flash light emitting of the energy with solar energy.
Technical solution of the present utility model is: a kind of solar energy flash light emitting, be provided with solar cell, and be connected to charging circuit with solar cell, the output and the energy-accumulating element of charging circuit join; Be connected to oscillating switch circuit with energy-accumulating element, oscillating switch circuit and light-emitting component join; Also be connected to oscillatory trigger circuit with solar cell, the output and the oscillating switch circuit of oscillatory trigger circuit join.
Step-down, filtering, the mu balanced circuit of described charging circuit for constituting by resistance R 1, R2, R9, R8, diode D1 and capacitor C 1.
Described energy-accumulating element is an electric capacity.
Described oscillatory trigger circuit is for being provided with triode V1, be connected to resistance R 3, R4 between the base stage of triode V1 and the emitter stage, the joint of resistance R 3, R4 and capacitor C 2 are joined, capacitor C 2 is joined with the base stage of triode V2, be connected to resistance R 5 with the emitter stage of triode V2, the base stage of the other end of resistance R 5 and triode V1 is joined, and is connected to resistance R 8 with the colelctor electrode of triode V2.
Described oscillating switch circuit joins for oscillating circuit and triode V3, the V3 that is made of inductance L 1, capacitor C 3, C4.
The utility model is to be the luminous device of the energy and sparkling with solar energy, can either save electric energy and also overcome the use disadvantages such as environmental pollution that battery brought.Circuit structure is simple, energy-absorbing, accumulation of energy when need not to be provided with light-sensitive element and control circuit and just can realize sunshine, and flicker is luminous during no sunshine.Be applicable to the various occasions that need flash caution such as different kinds of roads direction board, ground indicator lamp, engineering warning lamp.
Description of drawings:
Fig. 1 is the schematic block circuit diagram of the utility model embodiment.
Fig. 2 is the circuit theory line map of the utility model embodiment.
The specific embodiment:
Below in conjunction with the description of drawings specific embodiment of the present utility model.As shown in Figure 1: be provided with solar cell, be connected to charging circuit with solar cell, the output and the energy-accumulating element of charging circuit join; Be connected to oscillating switch circuit with energy-accumulating element, oscillating switch circuit and light-emitting component join; Also be connected to oscillatory trigger circuit with solar cell, the output and the oscillating switch circuit of oscillatory trigger circuit join.
As shown in Figure 2: energy-accumulating element is a capacitor C 5.Light-emitting component is a LED.Step-down, filtering, the mu balanced circuit of charging circuit for constituting by resistance R 1, R2, R9, R8, diode D1 and capacitor C 1.Oscillatory trigger circuit is for being provided with triode V1, be connected to resistance R 3, R4 between the base stage of triode V1 and the emitter stage, the joint of resistance R 3, R4 and capacitor C 2 are joined, capacitor C 2 is joined with the base stage of triode V2, be connected to resistance R 5 with the emitter stage of triode V2, the base stage of the other end of resistance R 5 and triode V1 is joined, and is connected to resistance R 8 with the colelctor electrode of triode V2.Oscillating switch circuit joins for oscillating circuit and triode V3, the V3 that is made of inductance L 1, capacitor C 3, C4.
Operation principle: when solar irradiation, solar cell E power supply abundance, charging circuit is to capacitor C 5 chargings.Triode V1 in the oscillatory trigger circuit ends by the triode V4 in, the oscillating switch circuit, and LED is not luminous.When solar irradiation is not enough, electric weight deficiency among the solar cell E, charging circuit stops charging, the triode V4 conducting in triode V1 conducting, the oscillating switch circuit, LED is luminous.Because the continuous recurrent state that triode V3, V4 in the oscillating switch circuit are in conducting all the time, end, so LED will constantly repeat circulation luminous, that extinguish, and promptly when solar irradiation is not enough, light emitting diode will constantly glimmer luminous.
