Abstract

The utility model discloses a device which uses sunlight to charge storage batteries and is used for supplying power to daylight lamps. The utility model is mainly characterized in that a solar energy board is independently separated; a charge and discharge circuit, the storage batteries, and a daylight lamp are installed together; a discrete structure is formed. Compared with the existing devices, the utility model has the advantages of easy use, not easily aged circuit board, etc., and furthermore, a long charging time is effectively ensured for the device.

Description

Solar lighting device

The utility model relates to a kind of device that utilizes sunshine to charge a battery and be used for powering to fluorescent lamp.

The Solar lamp device of selling on the existing market mainly comprises solar panels, charge-discharge circuit, battery and fluorescent lamp, and all these parts all be fitted together form as a whole.When this class Solar lamp device uses, will remove in the daytime to the open air, move back to indoor night again, exists following deficiency:

At first, very inconvenient in the use, and often move and easily cause Solar lamp to be broken;

Secondly, people forget easily or are difficult to punctual carrying apparatus, fail to reach capacity and cause not charge a battery or charge;

Moreover circuit board often is in irradiation under the daylight, and is easily aging in advance.

The purpose of this utility model is to overcome above-mentioned deficiency and a kind of improved Solar lamp device is provided, and it has easy to use, difficult aging characteristics, and assurance device has the long charging interval effectively.

Its purpose realizes like this: this device comprises solar panels, charge-discharge circuit, battery and fluorescent lamp, wherein, charge-discharge circuit, battery and fluorescent lamp are loaded on together, solar panels are independently divided come, and by lead they are linked together, become the branch body structure.During use, solar panels can be positioned over the open air for a long time, and place charge-discharge circuit, battery and fluorescent lamp indoor.

Like this, device of the present utility model is owing to adopt the branch body structure, solar panels can be positioned over the open air for a long time, people are Handling device often, and can avoid owing to frequent carrying apparatus Solar lamp being broken, simultaneously, battery can obtain the long charging interval, guaranteed to have enough electric energy to power, moreover wiring board is owing to be subjected to the time of illumination also to be not easy to less wear out to fluorescent lamp.

Fig. 1 is a schematic diagram of the present utility model;

Fig. 2 is the circuit diagram of a kind of concrete charge-discharge circuit of the utility model.

Below in conjunction with accompanying drawing the utility model is done concrete detailed description the in detail:

With reference to shown in Figure 1, solar panels 1 divide independently and come, become an independent part, charge-discharge circuit 2, battery E and fluorescent lamp 3 then are fitted together and become another part, solar panels 1 couple together by electric wire 4 and charge-discharge circuit 2, wherein, solar panels 1 can be positioned over the open air for a long time, and charge-discharge circuit 2, battery E and fluorescent lamp 4 can place indoor a certain position together.Be the course of work of charge-discharge circuit below: with reference to shown in Figure 2, solar panels 1 are converted to direct current with solar energy, through electric wire and DC plug, to battery E charging, and utilize diode D ₁Unilateral conduction, prevent that electric energy from flowing backwards and damage solar panels; In charging process, since the effect of 7V Zener diode, transistor BG ₂Base terminal about 7V, and before battery E do not reach capacity, its voltage is all below 7.6V, thereby transistor BG ₂End, the electric current major part flows to battery E, and when battery E was saturated, its voltage reached 76V, at this moment transistor BG ₂Conducting makes the electric current major part by bypass, thus protection battery E; Switch k on the closure makes battery E discharge to the fluorescent lamp power supply, at this moment, and by transistor BG ₁, transformer T, capacitor C ₃And resistance R ₁The anti-blocking circuit of forming partially makes transistor BG ₁Conducting---ends---the conducting circulation repeatedly, causes the variation of electric current in the elementary circle of transformer T, makes coil T ₃Under flux interaction, obtain alternating current and fluorescent lamp is lighted.

Claims

1, a kind of Solar lamp device comprises solar panels, charge-discharge circuit, battery and fluorescent lamp, it is characterized in that, described solar panels divide independently and come, become an independent part, described charge-discharge circuit, battery and fluorescent lamp then are loaded on together, become another part.
