Description

  The present invention relates to a lighting element incorporating a solar cell and a solar LED light using the lighting element.

A lighting element comprising a solar cell and a power supply unit comprising a storage battery that stores electricity generated by the solar cell, and an LED that emits light from the power supply unit via a lighting switch, is incorporated in the body. A portable charger has been proposed in Japanese Patent No. 3665062 (Patent Document 1).
However, since the illumination switch that lights the LED in Patent Document 1 is operated by pressing the lighting button at a specific part, it takes time to press the lighting button in the dark.
Japanese Patent No. 3665062

  In view of the above, the present invention provides a lighting element and a solar LED light, which are extremely simple to turn on an LED by power of a solar cell even in the dark.

The lighting element according to claim 1 of the present invention is a power supply unit that includes a solar cell and a storage battery that stores electricity generated by the solar cell, and a lighting switch having a switch pressing unit. In an illumination element consisting of LEDs that emit light with
The illumination switch serves as a mirror plate having a mirror surface at the switch pressing portion.
A solar LED light according to claim 2 is composed of the illumination element according to claim 1 and a flat case having a required shape in a plan view for accommodating the illumination element, and the light receiving surface of the solar cell is exposed on one side and the other side. A mirror plate with an exposed mirror surface is disposed on one side, a strap attaching portion is provided on one side, and the LED irradiation surface is exposed on the other side facing the one side.

  According to the present invention, the battery is not required to be replaced, and a flat end plate is used as the switch pressing portion, so that the LED can be immediately turned on even in the dark, and structurally, it is required for members such as push buttons and slide switches. It is a simple structure with reduced costs, and can also be provided as a stylish mirror.

  The end plate in the present invention is, for example, one that is pressed by itself, and that is superimposed on and pressed on a flexible material by an insulating material. The single end plate is deformable by an insulating material, and is flexible. Rigid materials can be used as materials.

The present invention will be described with reference to an embodiment. As shown in FIG. 2, the upper case 1 having a substantially rectangular shape in plan view has an opening 3 in the recess 2 and a recess 4 in the lower surface. A circular arc recess 5 is formed in the center of this, a strap attaching portion 7 penetrating a small hole 6 is protruded on the right side, and fitting pins 8 are suspended on the left and right and on the right and left, respectively.
And the illumination element a connects the electric power supply part 9 which consists of the solar cell 9a and the storage battery 9b superimposed on the back surface, one positive electrode 10 to the positive electrode of the electric power supply part 9, and the other negative electrode 11 The LED 12 is connected to the negative electrode of the storage battery 9b, and the end plate 13a is a switch pressing portion in the illumination switch 13 that presses the negative electrode.
On the other hand, the lower case 14 has the same shape as the case 1 in plan view, and an inspection window 16 is opened in the concave portion 15, and a fitting convex portion 17 that fits in the fitting concave portion 4 of the upper case 1 is formed on the upper surface. A circular arc recess 18 is formed in the left center, and fitting holes 19 for fitting the fitting pins 8 are provided in the left and right and right and left and right, respectively.
Therefore, the solar cell 9a having the light receiving surface on the lower surface is accommodated in the concave portion 15 of the lower case 14, the light receiving surface is exposed from the observation window 16, the arc surface of the LED 12 is fitted into the arc concave portion 18, and the negative electrode of the storage battery 9b is inserted. The upper surface is covered with an insulating material 21 having an opening 20 in the center and having elastic restoring force, and the negative electrode 11 of the LED 12 is passed from the upper surface of the insulating material 21 to the negative electrode of the storage battery 9b through the through hole 20. A mirror plate 13a with a mirror surface 13b as the upper surface is placed on the negative electrode 11.
In this state, the fitting convex portion 17 of the lower case 14 is fitted into the fitting concave portion 4, the arc surface of the LED 12 is fitted into the arc concave portion 5 of the upper case 1, and the fitting pin 8 is inserted into the fitting hole 19. The upper case 1 is put on the lower case 14 and the mirror surface 13 b of the end plate 13 a of the illumination switch 13 is exposed from the observation window 3 of the upper case 1.

The solar LED light A shown in FIG. 1 is provided by attaching the strap 22 to the small hole 6 of the strap attaching portion 7 of the upper case 1 assembled in this way.
This strap is used with the strap 22 attached to an automobile key holder (not shown) or the like, but in use, the -electrode 11 of the LED 12 contacts the -electrode of the storage battery 9b simply by pressing the end plate 13a. Becomes a closed circuit and the LED 12 lights up.
In this way, there is no operation of a specific part such as a push button or a slide switch, and the lighting switch 13 is turned off by the restoring force of the insulating material 21 due to the release of the pressing force, so that it is very easy to turn on / off the LED 12 in the dark. In addition, it is easy to insert an engine key of a car and to open and close a door lock, and since the lighting operation portion has a mirror surface 13b, it is also used as a stylish mirror.
In addition, since LED12 currently used is 7000 mcd, since visibility is favorable and it can also confirm from 1 kilometer away, it can be utilized also as an outdoor camp or a mountaineering goods. Moreover, in the illumination element a of the present invention, even if a flat plate without the mirror surface 13b is used instead of the end plate 13a, there is no operation of a specific part, and the elastic restoring force of the insulating material 21 is exerted by pressing and releasing the flat plate. Thus, as long as the illumination switch 13 is turned on and off, it belongs to the technical scope of the present invention. In addition, indirectly operating the ON / OFF switch via the end plate 13a is an item that can be easily recalled from the present invention.

  Since the present invention can be used by being housed in a key chain of an automobile, the demand is greatly expected as a product that matches the automobile society and as a leisure article.
