Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a portable lighting device, and more particularly, to a portable lighting device that can be used for a long period of time without worrying about battery life and replacement time by combining an LED and a solar panel.

[0002]

[Prior art]

 Most of portable lighting devices that have been put into practical use in the past use a battery as a power source, and there is also a type in which a small generator is turned on by using a gripping force and turned on.

[0003]

[Problems to be solved by the invention]

 However, when a battery is used as the light source as described above, when the battery is exhausted, its function cannot be performed and the battery needs to be replaced, but when the battery cannot be obtained due to a disaster or a remote place. It is useless for something like that. In addition, although the power generation type has no problem in use for a short time, operation for turning the generator was always required, and stable brightness could not be secured.

An object of the present invention is to solve the problems of the prior art, and to provide a practical and reliable operating portable lighting fixture.

[0006]

[Means for Solving the Problems]

 In order to achieve the above object, the present inventors have conducted intensive research and found that it is effective to combine a low power consumption LED (Light Emitting Diode) with a solar panel battery. We have completed the present invention.

That is, according to the present invention based on the above knowledge, a solar panel is mounted on one wide side of a rectangular case that can be divided into two parts vertically, and a portable case is mounted on the other wide side of the rectangular case. Attach a light source LED to one of the narrow case longitudinal end surfaces and one of the narrow case longitudinal side surfaces, and attach a light source changeover switch to the other of the narrow case longitudinal side surfaces. The main feature is a portable lighting fixture characterized by a built-in battery inside the case to store the power generated by the solar panel, and wiring between the LED, light source switching switch and the battery.

Further, in the present invention, the LED on the side in the longitudinal direction of the narrow case is blinking, or the longitudinal end face of the narrow case to which the LED for the light source is attached is chamfered and rounded. The portable lighting fixture formed in the above is also the gist of the invention.

[0009]

[Embodiment of the invention]

 The configuration and operation of the present invention will be described. The portable lighting equipment according to the present invention generates electricity from a solar panel and stores it in a battery to use as a power source. In order to reduce power consumption, LEDs were used as light sources.

[0010] As shown in the drawings, the portable lighting device according to the present invention has a solar panel 1 attached to one wide side surface 7a of a rectangular case 7 which can be vertically divided into two parts. The portable hook 6 is attached to the wide side surface 7b.

The light source LEDs 2 and 3 are attached to the narrow case longitudinal end face 7c and the narrow case longitudinal side face 7d, and the other side face 7e in the narrow case longitudinal direction is provided with a light source changeover switch 5 The battery 4 for storing the power generated by the solar panel 1 is built in the case, and the LEDs 2 and 3, the light source switch 5, and the battery 4 are wired so as to be electrically connected.

In the present invention, the LED 2 can be used for illumination in white and the LED 3 can be used for blinking in red. These LEDs are switched and used by the light source switch 5.

The portable lighting fixture case of the present invention is made of wood, synthetic resin, metal or a combination thereof. The lighting side end of the case is chamfered as shown in the drawing, and the corners are rounded to facilitate handling. The battery is small and lightweight, so it can be stored without taking up space in a car, near a window, etc.The battery can be charged by a solar panel with sunlight or indoor lighting while it is being stored or while carrying it. is there. When the LED is blinking, it can also function as a safety light by attaching it to a belt, cover, or the like with the hook 6.

As the LED used in the present invention, for example, a white LED (trade name: NSPW500BS) manufactured by Nichia Corporation, a red LED (trade name: GL5UR44) manufactured by Sharp Corporation, solar As the panel, a brand name of BP-376634C manufactured by Panasonic Corporation, and a NiCd battery (brand name: KR0.3AA-2) manufactured by GS Melcotech Co., Ltd. as a battery are suitable, but equivalent performance is obtained. It is not limited to these as shown.

[0015]

【Example】

 A specific example of the present invention will be described. A 2 mm thick ABS resin (acrylonitrile / butadiene / styrene copolymer resin) that is 100 mm long, 55 mm wide and 20 mm wide and can be assembled in two parts in the width direction is used as a lighting fixture case. The corner of the narrow lateral end face is rounded, and a white light source LED (trade name: NSPW500BS) or a flashing red LED (trade name: GL5UR44) is provided in the middle of the narrow vertical end face. Attach, and on the opposite side, attach a switch for light source switching. A solar panel (product name: BP-376634C) is attached to one of the wide sides of the case, and a portable hook made of PBT (polybutylene terephthalate) is attached to the other side. A battery (product name: KR0.3AA-2) is fixed in the case, and wiring is performed between the LED, the solar panel, and the switch for switching the light source.

Prior to use, the battery is charged by exposing the solar panel to sunlight. Charging is completed in 10 hours in the case of direct sunlight. In the case of using only lighting, it was possible to use for 15 hours, in the case of blinking only, for 30 hours, and in the case where both were used alternately, the above-mentioned intermediate time could be used depending on the usage ratio. When the lighting equipment is not used, it is placed in a place where sunlight shines on the solar panel, so that the battery is charged and ready for use.

[0017]

[Effect of the invention]

 Since the present invention is configured as described above, it can be used as a portable lighting device without worrying about battery consumption, and is very convenient and practical because of its small size and light weight. Useful.
