SOLUTION: The main body is provided with a light unit, a secondary battery, an electric control unit and a solar cell panel, and the secondary battery can be charged with electric energy generated by the solar cell panel via the electric control unit. At the same time, it is a solar cell type flashlight in which the secondary battery can light the electric lamp unit via the electric control unit.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This device is a solar-powered flashlight, which is used in remote areas and in emergency situations.

[0002]

[Prior art]

 Conventional flashlights include a dry battery type and a commercial power source rechargeable type. In the dry battery type flashlight, the lighting part is turned on by the primary battery, and in the rechargeable flashlight, the secondary battery is charged by the commercial power source of 100, and the secondary battery is charged by the secondary battery. The lighting fixture is lit.

[0003]

[Problems to be solved by the device]

 However, since the dry battery type flashlight uses the primary battery, it cannot be used when the battery is exhausted and the dry battery must be replaced when it is used. There was a case that it was not very convenient to use. On the other hand, a commercial power rechargeable flashlight can be recharged at any place because it requires recharging from a 100V power source, though it does not require battery replacement. Since it is necessary to recharge the battery, it is easy to forget to charge it, which is not convenient for use.

An object of this invention is to eliminate such inconvenience.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, in a solar cell-type flashlight according to the present invention, a main body is provided with a light section, a secondary battery, an electric control section, and a solar cell panel, and the above-mentioned electric control section is used. Since the secondary battery can be charged with the electric energy generated by the solar cell panel and the secondary battery can be turned on by the secondary battery via the electrical control unit, the secondary battery can be turned on if there is sunlight. It can be charged and the lighting unit can be turned on by this secondary battery.

Further, the main body is composed of a synthetic resin lighting part and a synthetic resin body part, and a fitting insertion hole is formed on a front surface of the body part and a protrusion is formed on a rear surface of the lighting part. If this protrusion is inserted into the insertion hole of the body with almost no gap and a stopper is formed at the tip of this protrusion, the body and the lighting fixture can swing slightly. Therefore, as a result of being able to absorb the shock received by these parts, it is possible to prevent damage when the flashlight is dropped or hit somewhere.

Embodiments

 1 to 3, 10 is a solar cell type flashlight, and 1 is its main body. The main body 1 is composed of a lighting portion 11 made of synthetic resin and a body portion 12 made of synthetic resin. The body 12 has a fitting hole 121 on the front surface. The lighting unit 11 has a protrusion 111 on the rear surface. The lighting portion 11 is connected to the body portion 12 by inserting the protruding portion 111 into the fitting insertion hole 121 of the body portion 12 with substantially no gap. Incidentally, 112 is a retaining member and is integrally formed at the tip of the projecting portion 111.

Reference numeral S denotes a solar cell panel, which is fitted into the side surface opening 1 c of the body 12 and is fitted into the step portions 1 d and 1 d. The solar cell panel S converts sunlight into electric energy.

A secondary battery B is housed inside the body 12. The secondary battery B is positioned by the locking holders F1 and F2. The secondary battery B is for charging the electric energy generated by the solar cell panel S. Incidentally, F is a hook for supporting the secondary battery.

Next, C is an electric control unit, which is installed inside the lighting unit 11. The electric control unit C charges the secondary battery B with the electric energy generated by the solar cell panel S, or turns on the electric lamp unit L described later by the secondary battery B. Further, the electric control unit C allows the flow of current from the solar cell panel S to the secondary battery B and the light bulb L, but has a backflow prevention function of preventing backflow from the load side to the solar cell panel S, and a solar cell. It has an overcharge prevention function from the panel S to the secondary battery B and an overdischarge prevention function from the secondary battery B to the load L.

Reference numeral L denotes an electric light unit, which is installed on the front surface of the lighting unit 11. The electric lamp unit L is turned on by discharging the secondary battery B. In addition, H is a handle, 1a and 1b are leg sides, both are installed on the body 12, and the lighting switch SW is installed on the lighting unit 11.

This solar cell type flashlight has the above-mentioned configuration, and is properly leaned against the stand G as shown in FIG. 2 during the daytime or when not in use. With this, the sunlight directly illuminates the solar cell panel S, and the charging operation to the secondary battery B is sufficiently effectively performed. When used at night, it is lit by the discharging action of the secondary battery, and the illuminance is kept in the best state of full charge each time, and sufficient illuminance can be secured at night use. Furthermore, the greatest characteristic use of this charging / discharging method is that the best illuminance can be obtained at any time regardless of the frequency of use, and maintenance such as battery replacement is completely unnecessary.

The present invention is not limited to the above embodiment, and design changes can be made within the scope of the invention. For example, the arrangement position and design of the solar cell S can be changed appropriately.

[Effect of device]

 In the solar cell type flashlight according to the present invention, a main body is provided with a light section, a secondary battery, an electric control section, and a solar cell panel, and electric energy generated by the solar cell panel via the electric control section. The secondary battery can be charged and the electric light can be turned on by the secondary battery via the electric control unit. Therefore, if there is sunlight, the secondary battery can be charged and the secondary battery can be charged. The lighting unit can be turned on by the secondary battery.

Therefore, if this solar cell type flashlight is used, battery replacement is unnecessary, and since it is not necessary to positively charge from a 100V power source, it can be charged anywhere and can be charged. It is hard to forget, so its convenience is extremely high.

Further, the main body is composed of a lighting part made of synthetic resin and a body part made of synthetic resin, and a fitting insertion hole is formed on a front surface of the body part and a protrusion is formed on a rear surface of the lighting part. If this protrusion is inserted into the insertion hole of the body with almost no gap and a stopper is formed at the tip of this protrusion, the body and the lighting fixture can swing slightly. Therefore, as a result of being able to absorb the shock received by these parts, it is possible to prevent damage when the flashlight is dropped or hit somewhere.
