Abstract

PURPOSE: To provide a lighting system which functions as a search light or a lantern as occasion demands by changing the direction of a double-face reflecting mirror having a recessed type cross section upward or downward by attaching and detaching as the occasion may demand and further fitting it into an emitter holder for installation. CONSTITUTION: In a double-face reflecting mirror 9 with a recessed type cross section, the direction and the position of the double-face reflecting mirror 9 are set and adjusted by fitting, sliding, fixing, attaching and detaching a hole 9a provided in its central part in an emitter holder 7 planted upright in a fixing plate 4. The double-face reflecting plate 9 is installed and fixed in a predetermined place, for instance, of the upper surface of the fixing plate 4 and the inner surface of the upper end of a shade 10 by engaging the opening end edge part of the double-face reflecting mirror 9 with ribs for fixation respectively installed. Also, the top part of the shade 10 is made into a lens face 10b. The double-face reflecting mirror 9 having a recessed type cross section is installed downward, and when the engaging part 12a of a handle 12 is engaged for installation with handle fixing holes 11, 11a and a power supply switch 6 is turned on, light from an emitter is emitted as reflected light reflected in the external downward face of the double-face reflecting mirror 9 and also as scattered light from the side wall of the shade 10 and the top lens face 10b, and it functions as a lantern.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lighting device, and more particularly to a lighting device which uses a battery as a power source and exhibits a function of a lantern or a searchlight by switching.

[0002]

2. Description of the Related Art An illuminating device which can be made to function as a lantern or a searchlight by switching the structure is known, for example, from Japanese Patent Laid-Open No. 52-98376.
That is, a lid portion having a top lens portion is slidably fitted and attached to a base portion for mounting and holding a light source including a battery as a power source, while the light source side is interposed between the top lens surface of the base portion and the lid portion. Arrange an expandable spring that gradually increases in diameter and winds,
There is known a lighting device that causes the elastic spring to act as a reflecting mirror (searchlight function) or irradiates / scatters light between windings of the elastic spring (lantern function) by sliding the lid. There is. In the configuration of the lighting device, the shades installed on the lid and the base are overlapped or unfolded as the lid slides, thereby facilitating the searchlight function and the lantern function. ing. In addition, a so-called handle is pivotally attached to the top lens surface side of the lid, and is set up when used as a lantern and tilted when used as a searchlight.

[0003]

However, in the case of the illuminating device having the above-mentioned configuration, there are the following inconvenient problems in practical use. That is, not only is the structure complicated, but the expansion spring functions as a reflecting mirror by compression (compression bonding) of the lid portion with respect to the base portion, so that the expansion spring is necessarily displaced and deformed. You may not get the concentrated light. Further, when used as a searchlight, the handle is tilted along the lens surface, so that the function as a handle is lost.

As described above, the conventional lantern-searchlight switching type illuminator has a complicated structure and requires mechanical precision in order to have a required function, which causes a problem in cost. In addition, in terms of the searchlight function, the fact that the function switching is not sufficient can be said to be sufficiently satisfactory for practical use in terms of centralized lighting and handling.

The present invention has been made in view of such circumstances, and an object thereof is to provide an illuminating device which can easily perform a handling operation and can surely obtain a required concentrated light or scattered light by switching built-in switches. To do.

A first lead portion, a fixing plate engaged with and attached to the opening of the main body, and a second lead portion arranged on the fixing plate for connecting the other terminal of the battery housed and attached to the main body,
A power switch disposed on the outer wall of the main body for opening and closing a battery connection circuit, and a light emitter that is mounted on a fixed plate with a light emitter electrically connected to the second lead portion being supported at the tip. A holder, a double-sided reflecting mirror having a concave cross-section that is detachably fitted and attached to the luminous body holder, a double-sided reflecting mirror having a concave cross-section and the light-emitting body, and the opening end side is detachably fitted into the opening of the main body.・ Shade to be mounted, handle fixing holes provided in the side wall portion of the main body as a pair substantially horizontally and substantially vertically, and a detachable / engageable member with respect to the pair of handle fixing holes. An illuminating device, comprising: a joint part, and a handle, the grip part of which is set horizontally or vertically by switching pairs. According to a second aspect of the present invention, in the illumination device according to the first aspect, a plurality of batteries are housed and mounted in the tubular main body.

According to a third aspect of the present invention, in the lighting device according to the second aspect, a plurality of batteries housed and mounted in the cylindrical main body are connected in series.

[0008]

According to the first aspect of the present invention, the double-sided reflecting mirror having a concave cross-section is appropriately attached / detached / changed upward (concave surface is upward) or downward (concave surface is downward) to be fitted and mounted in the light emitter holder. , The light emitted from the luminous body is effectively focused and emitted on the inner surface of the reflecting mirror facing upward, and functions as a required lantern by being effectively reflected and scattered by the outer surface of the reflecting mirror facing downward. . On the other hand, by changing the engagement of the engaging portion of the handle with the pair of handle fixing holes provided on the side wall portion of the main body, the handle gripping portion is made parallel along the outer peripheral surface of the main body or along the end surface of the main body. Since they are collimated and parallelized, they can be handled appropriately as searchlights or lanterns.

According to the second aspect of the invention, since the number of batteries housed and mounted in the cylindrical body is plural, the light amount according to the first aspect is increased and the action of the searchlight or the lantern is improved. .

According to the invention of claim 3, the operation according to claim 2 is further improved due to the plurality of batteries housed and mounted in the cylindrical main body and connected in series.
