Abstract

PURPOSE:To form a small and lightweight light emitting device which has resistance against vibration and impulse and which does not need exchange of batteries by charging a secondary battery with electric power from a solar cell and also switching off a light emitting device when the outer lid is closed, whereas when the outer lid is closed lighting a light emitting means using the secondary battery. CONSTITUTION:While an outer lid 11 is closed, a switch 4 is opened and a secondary battery 3 is charged with electric power generated by a solar battery 1. The switch 4 is closed by opening of the outer lid 11, and the electric power of the secondary battery 3 is converted to alternative current by an oscillating transistor 6, and voltage is raised to 100V by a step-up transformer 9 so that a fluorescent lamp 2 is lighted. While the outer lid 11 is closed, the fluorescent lamp 2 is pressed and protected by a cushioning material 14 and so will not be broken by vibration nor impulse.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a portable light emitting device, and in particular to a solar cell and a light emitting device.
The present invention relates to a solar cell-equipped portable light-emitting device equipped with a secondary battery.

[Prior Art] In recent years, with the increase in leisure time, many people are going out for outdoor leisure activities such as camping, fishing, and mountain climbing.
Flashlights, battery-powered fluorescent lamps, and the like are often used as portable light-emitting devices that can be used outdoors.

[Problems to be Solved by the Invention] However, most conventional portable light emitting devices use dry batteries (flashlights that use incandescent bulbs have the disadvantage that batteries are rapidly consumed and require frequent battery replacement). Similarly, even battery-powered fluorescent lamps that consume relatively little electricity have the disadvantage of requiring battery replacement as the batteries wear out. Increased weight is a big problem, especially when climbing mountains.

Additionally, devices using fluorescent lamps have the disadvantage that the fluorescent lamps are weak against shock and easily break.

[Object of the Invention] In view of the problems of the prior art described above, the present invention aims to realize a portable light emitting device that does not require battery replacement, is small and lightweight, and is resistant to vibrations and shocks.

[Means for Solving the Problem] In order to achieve the above-mentioned object, the present invention provides a portable light-emitting device comprising: a light-emitting means; an outer lid that covers the light-emitting means and has a solar cell on its outer surface; A secondary battery connected to the battery, a switch that is linked to the opening and closing of the outer cover, and the action of the switch allow the power from the solar battery to be transferred to the second battery when the outer cover is closed.
To provide a portable light-emitting device with a solar cell, characterized in that the light-emitting device is turned off when the secondary battery is charged, and the light-emitting means is turned on by the secondary battery when the outer cover is open. .

Further, the outer cover has a cushioning material inside, and when closed, the cushioning material is pressed against the light-emitting means to protect the light-emitting means. It is something to do.

[Function] The present invention uses the power generated by a solar cell as a power source for a light-emitting device, and by charging it into a secondary battery, there is no need to worry about the battery running out as long as light can be obtained, and there is no need to replace the battery. A portable light emitting device can be realized. Furthermore, by attaching an openable outer cover with a cushioning material on the inside to protect the light emitting means such as fluorescent lamps and light bulbs inside, the device can be made resistant to vibrations and shocks.

Further, FIG. 2 shows a state in which the outer cover 11 is closed, and in this state, the switch 4 shown in FIG. 1 is turned off, and the fluorescent lamp 2
is turned off, and the power generated by the solar cell is charged to the secondary battery 3 shown in FIG.

Further, in this state, the fluorescent lamp 2 is protected by being held down by the cushioning material 14, so that it will not be damaged by vibration or impact.

As mentioned above, the solar cell-equipped portable fluorescent lamp of this embodiment is kept with the outer cover of FIG. The structure is such that light 2 lights up.
