[Industrial applications]

 The present invention relates to a portable electric lamp, and more particularly to a portable electric lamp that does not forget to turn off the electric lamp.

[0002]

[Prior art]

 A portable electric lamp uses a plurality of dry batteries as a power source and is usually composed of a main body portion and a lens frame portion. The main body consists of a body that houses the dry batteries and a switch, while the lens frame body has a lens and a reflector attached to the lens frame, and a miniature bulb is attached to the reflector.

When the portable electric lamp is placed on the table after use, the portable electric lamp is formed to lie sideways or the lens frame is placed downward. , It is more stable to put the lens frame down than to lay it sideways. Therefore, when such a portable electric lamp is placed on the table after use, the lens frame is often placed down.

By the way, when the portable electric lamp is placed on the table with the lens frame facing down, the front edge of the lens frame is flat and closely adheres to the table. Therefore, it is possible to check the lighting state. Can not. For this reason, it is often left lit.

As a solution to the above-mentioned problems, a hand-held electric lamp disclosed in JP-A-57-121101 is proposed. This lamp has several projections or ridges protruding from the front edge of the lens frame, or a bulge made of a transparent material attached to the front edge. As a result, a gap is created between the front edge of the lens frame and the base so that the irradiation light can leak from this gap.

However, the hand lamp is turned off and turned off only when a person confirms the irradiation light leaked from the gap between the front edge of the lens frame and the base. For this reason, when the surroundings are bright, for example, the leakage of the irradiation light may not be noticed, and if the leakage of the irradiation light is not noticed, the electric lamp is naturally forgotten to be turned off.

[0007]

[Problems to be solved by the device]

 The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a portable electric lamp that is automatically turned off when the lens frame is placed on a table. .

[0008]

[Means for Solving the Problems]

 The above object of the present invention is to provide a portable light having a lens frame, in which the pin plunger of the micro switch which is opened when the pin plunger is pushed is arranged so as to project to the front edge of the lens frame. Achieved by the feature portable light.

The micro switch according to the present invention is such that when the pin plunger is pushed, the switch is opened and the current is cut off, and in the normal state, the switch is closed and the current is conducted. This micro switch is connected in series with the main switch for lighting the miniature bulb. Therefore, the miniature bulb is turned off when either the micro switch or the main switch is open.

In the above micro switch, the pin plunger needs to be pushed in when the micro switch is placed on the table with the lens frame facing down. Therefore, in the present invention, the pin plunger of the micro switch is projected to the front edge of the lens frame. The location of the micro switch may be the peripheral portion of the lens frame, but the one housed inside the lens frame is preferable in terms of appearance and handling.

[0011]

[Operation] When the light is on and the lens frame is placed on the table with the lens frame facing down, the pin plunger of the micro switch is pushed by the table and pushed into the lens frame, and the micro switch is opened. The light will be turned off.

【Example】

 Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings.

FIG. 1 is a side view showing an embodiment of the portable electric lamp of the present invention, and FIG. 2 is a perspective view showing another embodiment. These portable electric lamps include a body 3 for accommodating a plurality of dry batteries, a handle 4 (not shown in FIG. 2) and a main switch 5, a lens frame 1, a lens 9 and a reflector (not shown). No.) and a lens frame with a miniature bulb attached. Further, the lens frame of this portable electric lamp houses a micro switch, and the pin plunger 2 of the micro switch projects from the front edge of the lens frame 1.

FIG. 3 is a main electric circuit diagram of the portable electric lamp. The portable light uses a dry battery 8 as a power source. The micro switch 6 is normally in a closed state (conductive state) and is in an open state when the pin plunger 2 is pushed. This micro switch 6 is connected in series with the main switch 5, and when the main switch 5 is closed, the miniature bulb 7 lights up. On the other hand, when the pin plunger 2 is pushed in the lighting state, the micro switch 6 is opened and the current is cut off by the micro switch 6, so that the miniature bulb 7 is turned off.

[0015]

[Effect of device]

 Since the portable lamp of the present invention has the pin plunger of the micro switch protruding from the front edge of the lens frame, when the lens frame is placed on the table with the lens frame facing down, the micro switch will always operate automatically. Will disappear. Therefore, the portable electric lamp of the present invention can completely prevent forgetting to turn off the electric lamp, which is often seen in conventional products when the lens frame is placed down.
