The lower surface of the disk-shaped body (11) is provided with an offset surface (16) except for the peripheral edge portion (15) in contact with the photographing equipment, and is formed so as not to cause excessive friction.

An annular groove (17) into which the lower case (20) is fitted is formed on the upper surface of the disk-shaped body (11). With the fitting portion (21) of the lower case (20) fitted in the annular groove (17), the fixed washer (180) is sandwiched between the fixed convex portions (18) in the center of the annular groove (17). By fixing with the fixing screw (181), the main body portion (2) becomes relatively rotatable with respect to the mount portion (10). As a result, the light emitting body of the main body portion (10) can be freely directed in a desired direction.

The lower case (20) is substantially cylindrical, and the upper surface of the fitting portion (21) is a circular flat surface portion substantially the same as the outer diameter of the fixed washer (180), and is screwed from the substantially cylindrical upper surface side. It is exposed so that it can be stopped. At the same time, a battery area (22) for storing the button-type battery (40) is formed inside the cylinder.

In this embodiment, the battery region (22) is a space in which electrodes are not provided, and the electrodes (23) on the lower surface and the side surface of the button type battery (40) and the metal case (24) for conduction are the upper part described later. It is attached to the case (30) side. The upper case (30) is energized from the electrode (23) through a metal plate (24) for conduction. Therefore, the battery region (22) is accommodated together with the electrode and the metal case. In addition, one electrode of the button type battery may be provided on the lower case side.

As shown in the figure, the outer diameter of the photographic equipment lamp (1) is minimized while accommodating a button-type battery, has ease of turning, and is installed side by side with other members, for example, on a rig. The optimum size is configured without interfering with the case. From this point of view, it is most preferable that the lamp (1) for photographing equipment of the present invention has a substantially cylindrical shape and has an outer diameter in the range of 20 mm to 30 mm, particularly preferably about 1 inch.

A known rechargeable battery such as a lithium ion battery may be built in instead of the button type battery (40). For example, it may be used by connecting it to an external power source via USB or the like to charge the battery.

Concave knurls (25) are also provided intermittently on the side surface of the lower case (20) at right angles to the circumferential direction. The main body portion (2) can be rotated with respect to the mount portion (10) by putting a finger on the knurl (25).

A tact switch (34) is provided on the upper surface of the substrate (33), and the bottom of the switch member (35) exposed on the upper surface of the upper case (30) is in contact with the tact switch (34). Then, when the switch member (35) is pushed downward, the power is turned on and off by the tact switch (34). The mode of the switch is arbitrary.

A light emitting body (36) is provided on the upper surface of the substrate (33) together with a circuit such as a control IC. The light emitting body (36) is composed of an LED substrate (360) that stands upright to the substrate (33) and a chip-type LED (361) mounted on the LED substrate (360).

Since the chip-type LED (361) obtains the most illuminance in the direction perpendicular to the surface, the light emitted from the light emitter (36) is efficiently irradiated to the outside by this configuration. Since the irradiated light is emitted to the outside through the opening (37) provided on the side surface of the upper case (30), the light in the unnecessary direction is blocked from the chip type LED (361) and illuminates only the necessary part. be able to.

A transparent lens body (38) is fitted in the opening (37). The lens body (38) may be provided as a cover for preventing dust from entering the inside, or may be configured to change the thickness and refract it internally to control the irradiation direction. Further, a desired color such as red or blue may be added to adjust the emission color according to the use of the lamp.

When heat generation of the chip type LED (361) becomes a problem, heat conduction is easily performed to the upper case (30) through the LED substrate (360), peripheral parts and a heat conduction member such as metal, so that heat is easily wasted. It may be configured as.

The circuit on the substrate (33) may be configured so that when the switch member (35) is pressed, the light emitter (36) is turned on and automatically turned off in about 5 seconds to 3 minutes. .. This eliminates the need to bother to erase it. You can use both hands when shooting, and you can concentrate on shooting because you are not caught up in the work of erasing, which improves convenience at the shooting site. Further, by pressing the switch before it goes out, the lighting time may be extended again from that point.

Further, by applying or mixing a phosphorescent luminous pigment on the switch member (35), it is possible to make the location of the lamp (1) for photographing equipment and the switch member (35) easy to understand and improve the work efficiency in a dark place. ..
