JP2003141914A - Multifunction lighting tool - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide a multifunction lighting tool which has functions of both a flashlight and a footlight realizing conveniences of multifunction while overcoming faults each single-function flashlight or footlight has. SOLUTION: An outer power source and rechargeable battery are used in combination as a power source for a lighting tool. When it is used as a footlight, the outer power source is used by inserting its AC inlet into an outer power socket, in which case, it is lit only when people come near by the action of a human detecting sensor fitted in the vicinity of the light source. When used as a flashlight, the AC inlet is taken off from the outer power socket, the rechargeable battery is used as a power source, and turn on and off of the light source is done by a power source switch.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a multifunctional lighting device that can be used as a footlight in daily life but can be used as a flashlight when necessary. The footlight referred to here is a kind of lighting equipment that is installed at a certain place and is made for the purpose of illuminating the foot of a person passing through it.

[0002]

2. Description of the Related Art There is no product in which a flashlight and a footlight are combined together, and each is marketed as a single-function product. Also, conventional type flashlights use ordinary dry batteries as a power source. In addition, the power supply of a commercially available footlight combined with a human detection sensor is
Ordinary batteries or household power source is used. However, if a household power source is used, it will not light up during a power failure and will not function as a footlight.

[0003]

When a flashlight is stored for emergencies such as a power failure, the flashlight is useless when it is needed, due to battery life expiration or battery damage due to liquid leakage. There is. In addition, the storage location of the flashlight may be forgotten, or the storage location may be so dark that it cannot be used when necessary. The multi-function lighting device according to the present invention uses a rechargeable battery so that it can be used as a footlight while being charged on a daily basis. We are trying to solve the problem of not knowing the storage location.

[0004]

An external power source and a rechargeable battery are used together as a power source. A person detection sensor is arranged in the vicinity of the light source, and it functions as a footlight when fixed and powered by an AC inlet to an external power source such as a household power source, and the light source is turned on only when a person approaches.
At that time, the rechargeable battery is constantly charged by the charging circuit. Next, when you disconnect the flashlight from the external power source,
As a flashlight powered by a rechargeable battery, the light source can be turned on and off by turning the power switch on and off.

Further, an optical sensor is provided in the vicinity of the light source so that when the outside light is bright, it does not turn on even when a person approaches the footlight when it is used.

Further, a power failure detection circuit is provided so that when the power source is connected to an external power source and used as a footlight, when the external power source fails, the power failure is detected and the light source automatically turns on the light source. Set to.

BEST MODE FOR CARRYING OUT THE INVENTION Next, embodiments of the present invention will be described. In FIG. 1, the light source 1 uses a small incandescent light bulb (so-called miniature bulb), an LED, or the like, but a high-brightness LED that consumes less battery is preferable. It is also possible to use LEDs of a plurality of colors and switch the colors to change the emission color.

It is also possible to arrange a lens on the front surface of the light source so that the distance can be adjusted so that the convergence distance of the light flux can be adjusted according to the distance to the object, such as when used as a flashlight.

A pyroelectric sensor, an ultrasonic sensor, or the like can be considered as the human detection sensor 2, but a compact and low-priced pyroelectric sensor is preferable.

The AC inlet 3 for inputting the external power source is intended for electrical input from the external power outlet to the charging circuit 4, but also has a role of mechanically fixing the flashlight to the external power outlet during charging. . This is because when used as a footlight, it is necessary to fix the case 5 to an external power outlet installed on a wall surface or the like.

On the other hand, when the AC inlet is pulled out from the external power outlet and used as a flashlight, the protruding inlet is an obstacle in handling. Therefore, AC
It is convenient to let the inlet fit into the flashlight with a rotating (or sliding) mechanism.

When used as a flashlight, the power switch 6 is provided for the purpose of blinking the light source by turning it on and off. In FIG. 1, a slide switch is used as the power switch, but the type thereof does not matter.

In FIG. 1, an optical sensor 7 is shown, but this is required for claim 2 and not for claim 1.

The reason for providing the optical sensor is to save power when used as a footlight. The light source only needs to be turned on when it is dark, so make sure that it does not emit light when people approach it under conditions of a certain brightness or higher. Although a CdS cell, a photodiode, or the like can be considered as the optical sensor, a low-priced CdS cell is functionally sufficient.

FIG. 2 is a diagram for explaining the basic structure of the present invention. Here, the optical sensor 7 relates to claim 2, and the power failure detection circuit 10 relates to claim 3.

When an optical sensor is added in claim 2, the electric circuit related to the optical sensor is of course the light source lighting circuit 9
Is added to.

[0017]

According to the present invention, it can be used as a flashlight when needed while using it with a footlight in everyday life.
So to speak, a multifunctional lighting device can be realized. further,
With the multi-functionality, the problem of the conventional flashlight that the battery runs out when you need it, or you do not know where to put it, and the problem of the conventional external power supply type footlight that does not turn on at the time of power failure It has been settled.
