CN200993320Y - Solar torch - Google Patents

Abstract

The utility model relates to an electric torch of solar energy, which comprises a casing, a bulb, a glass cover, a light-collecting hood, a switch and a battery. On the wall of the casing, a solar battery board is installed, which is connected with the battery through a protective diode. The electric torch of solar energy receives solar energy through the solar battery board and converts solar energy into electric energy and saves that into the battery; after the battery is charged, the bulb is supplied with power. During the power supplying, the protective diode can prevent the electricity in the battery from flowing through the solar battery board. As the whole battery is supplied power by solar, no electric power is consumed. The utility model is environment friendly. More important is that the utility model is applicable for different applications, especially for outdoor operation.

Description

Solar electric torch

Technical field

The utility model relates to a kind of flashlight, relates in particular to a kind of solar electric torch.

Background technology

Flashlight is the emergency lighting instrument that people generally use, and existing flashlight is a kind of to be to use dry cell power supply, and another kind is to use battery-driven.Use dry cell to consume dry cell than very fast as the flashlight of powering, the replacing of dry cell is more frequent, and discarding of dry cell becomes big pollution sources day by day now, therefore needs to lower the use of dry cell.Can avoid the pollution problem of dry cell though use battery-driven flashlight, but this flashlight need use up the back at electric energy to charge by connecting civil power, but the place of many use flashlights all lacks civil power, especially people's operation in the open air the time, it is very impossible to come to the flashlight charging by civil power.

Summary of the invention

Goal of the invention of the present utility model is for providing a kind of solar electric torch, and this flashlight is powered by solar energy, also can use under the situation that lacks civil power, especially adapts in the open air and uses, and do not have the shortcoming of battery pollution environment.

To achieve these goals; solar electric torch of the present utility model; comprise shell, bulb, cloche, snoot, switch, battery, it is characterized in that: on the shell wall of described shell solar panel is housed, solar panel is connected with battery by a protection diode.

In order to prevent to damage solar panel and prevent to be covered with transparent protective shield on the described solar panel by the ash that falls on the solar panel.

Adopt above-mentioned technology; accept solar energy and become conversion of solar energy power storage to arrive in the battery by solar panel; rush to electricity back in the battery and just can give bulb powered, in power supply process, protect diode to have to prevent the flow through effect of solar panel of the interior electric current of battery.Because whole battery is that employing is solar powered, has therefore not only saved electric energy, has environmental-protection function, the more important thing is that can adapt to various places uses, and especially adapts to field work and uses.

The specific embodiment

With reference to shown in Figure 1, solar electric torch of the present utility model comprises shell 1, bulb 2, cloche 3, snoot 4, switch 9, battery 5, solar panel 6, protection diode 7, transparent protective shield 8.Wherein snoot 4 is positioned at the front end of shell 1; bulb 2 is housed in the snoot 4; be equipped with on the cover mouth of snoot 4 cloche 3 be used for blocks dust and the protection bulb 2; switch 9 and solar panel 6 are housed on the shell wall of shell 1; transparent protective shield 8 covers on the solar panel, is used for blocks dust and protects solar panel 6 not to be damaged.

Again with reference to shown in Figure 2; described bulb 2, switch 9; battery 5 constitutes a lighting circuit; solar panel 6 is connected in parallel on the battery 5; and protection diode 7 is connected between solar panel 6 and the battery 5; wherein protect the positive pole of the negative pole connection battery 5 of diode 7, the positive pole of protection diode 7 connects solar panel 6.

During charging; cut-off switch 9; allow the solar panel of this solar electric torch aim at sunlight; only need open switch 9 when use electricity back and just can be used to throw light on Deng having dashed; because the existence of protection diode 7; at this moment the electric current of battery 5 can instead not flow in the solar panel 6, and solar panel 6 is had protective effect.

Claims (2)

1, a kind of solar electric torch comprises shell, bulb, cloche, snoot, switch, battery, it is characterized in that: on the shell wall of described shell solar panel is housed, solar panel is connected with battery by a protection diode.

2, solar electric torch according to claim 1 is characterized in that: be covered with transparent protective shield on the described solar panel.
