[0002]

2. Description of the Related Art Illumination lamps mainly used for the above applications are disclosed in Japanese Patent Publication No. 2-10521, Japanese Patent Application Laid-Open No. 9-223403 and Japanese Patent Application Laid-Open No. 7-78501. What was done is known. Lamp device described in Japanese Patent Publication No. 2-10521 (hereinafter referred to as first prior art)
Is provided with a reflector inside the cylindrical body, and moves the reflector by rotating a ring-shaped member whose opening is covered with a transparent plate, and moves the reflector relative to a single bulb. By selectively displacing the first and second positions, the light flux of the bulb is most diffused when the reflector is displaced to the first position and converges most when displaced to the second position. The irradiation is switched.

A headlamp described in Japanese Patent Application Laid-Open No. 9-223403 (hereinafter referred to as a second prior art) is capable of switching the brightness of a single light bulb in two stages by rotating a switching knob. By adjusting the brightness of the bulb in accordance with the surrounding brightness, unnecessary consumption of the battery can be suppressed. Further, an electric illumination lamp (hereinafter referred to as a third prior art) described in Japanese Patent Application Laid-Open No. 7-78501 is provided with two light sources arranged in a juxtaposed state and individually corresponding to each of these light sources. And two switches of an electric circuit for controlling the turning on and off of the two light sources.

In the illumination lamp used for such an application, if two light sources are provided as in the third related art, when one of the light sources breaks, the other light source can be immediately switched to use.
Further, it is convenient that these light sources having different illuminances, luminescent colors or lifespans can be mounted and switched appropriately according to the situation. However, in the first and second prior arts described above, the brightness and the like of the light bulb can be switched in two stages, but since only a single light bulb is provided, the practical effects as described above are not obtained. I can't get it.

On the other hand, the electric lighting lamp of the third prior art is provided with two light sources, but is provided with two reflectors corresponding to these light sources, respectively. In the case of suppressing, the shape of each reflector becomes small, so that the light of each light source cannot be sufficiently diffused or converged, and illumination light of sufficient brightness cannot be obtained. On the other hand, if each reflector has a required size, the overall shape becomes large, which is difficult to use as a headlamp. Moreover, with this electric lighting lamp,
Since it has two reflectors and two switches,
The increase in the number of parts causes the configuration to be complicated and large, and the cost increases with the complexity of the configuration.

For this reason, the light source 1 positioned at the center S
Reference numeral 2 indicates that the negative contact portion 29 is connected to the battery in the battery case 3 through the negative connection terminal plate 32, and the drive power is supplied from the battery to light up. At this time, since the light source 12 is turned on in a state where the light source 12 is positioned at the central portion which is the focal position of the reflecting mirror 8a of the reflector 8, the luminous flux is efficiently converged after the emitted light is reflected by the reflecting mirror 8a. Alternatively, the light is diffused and emitted forward through the transparent plate 41. In order to turn off the light source 12, it is only necessary to rotate the rotary operation ring body 90 by 90 degrees in the right direction R to bring it to the state shown in FIG.

On the other hand, the rotary operation ring body 10 is shown in FIG.
When the rotary operation is performed in the right direction R from the state of (1), as shown in (d), the light source holder 13 is located at the hole edge surface of the operating hole 39 of the light source moving member 9 that rotates integrally with the rotary operation ring body 10.

At this time, as shown in FIG. 7E, the light source holder 13 is positioned such that the left light source 11 is positioned at the center S, and the left negative contact portion 30 is in contact with the negative connection terminal plate 32 of the holding portion 23. The piece 32a is superposed and electrically connected.

Therefore, the light source 1 positioned at the center S
In 1, the negative side contact portion 30 is connected to the battery in the battery case 3 through the negative side connection terminal plate 32, and the drive power is supplied from the battery to light up. At this time, since the light source 11 is turned on in a state where the light source 11 is positioned at the central portion which is the focal position of the reflecting mirror surface 8a of the reflector 8, the light emission is performed.
After being reflected by the light beam, the light beam is efficiently converged or diffused, and is irradiated forward through the transparent plate 41. When the light source 11 is turned off, it is only necessary to rotate the rotary operation ring body 90 by 90 degrees to the left L to bring it to the state shown in FIG.

As the pair of light sources 11 and 12, light sources having different light divergence, life, illuminance, or emission color are used, and these are switched on and off according to the application and purpose. Thus, the range of use as lighting can be expanded. Further, in the above-described illumination lamp, only a single reflector 8 is provided for the pair of light sources 11 and 12, and no power switch or the like is provided for each of the light sources 11 and 12, so that this configuration is simplified. The size of the reflector 8 can be set as large as possible while reducing the size and cost of the external shape of the entire illumination lamp, and the focal position of the reflecting mirror surface 8a of the reflector 8 can be used for any of the light sources 11 and 12. By turning on the light in a state where it is positioned at the central portion, it is possible to efficiently converge or diffuse any light emitted from the pair of light sources 11 and 12 on the reflecting mirror surface 8a and irradiate the light.

Further, in the illumination lamp, by performing a one-touch operation for rotating the rotary operation ring body 10, the desired light sources 11 and 12 can be selected and positioned at the focal position of the reflecting mirror surface 8a. Light source 1
Since the switching operation can be performed so that the power supply units 1 and 12 are automatically connected to the power supply, the operability is extremely high.

In the above embodiment, the lamp body 1
In this example, the belt holder 2 is fitted and fixed to the mounting plate 14, and is used for lighting when climbing or working freely using both hands by attaching to the head or helmet. If the handle is attached to the attachment plate 14 instead of 2, it can be used for the same purpose as a normal flashlight. In particular, when used as a headlamp for mountain climbing or the like, when one of the pair of light sources 11 and 12 breaks the ball, the other can be immediately turned on by rotating the rotating operation ring body 10, and extremely. It will be useful and effective.
