The present invention relates to a light mounted in a camcorder or a camera and used for indoor and night photographing. In particular, the present invention relates to a light that can arbitrarily adjust the reflection angle of light by varying an installation angle of a reflection shade.

The conventional general light is a simple fallopian tube type having a socket 30 for mounting a light bulb 20 on the front of the body A and a light bulb 20 inside the body A, as shown in FIG. The reflector 40 is fixed and configured.

However, this is fixed, so that the installation angle of the reflection shade 40 is always made only a certain angle, the light bulb 20 also has a fixed structure to maintain only a constant distance with the light emitting window 10, the distance from the subject It was not possible to obtain a good quality image due to the impossibility of adjusting the light reflection angle and light brightness.

The present invention has been made in order to solve the above-mentioned general drawbacks, and the socket holder having a reflection shade that can be installed in the motor shaft of the drive motor to extend the fold in the circumferential direction to the screw coupling means The purpose of the present invention is to provide a light that can arbitrarily adjust the reflection angle of the light and the brightness of the reflected light by allowing the installation angle of the reflecting shade to be variablely adjusted as the driving motor is rotated forward and backward by inserting and configuring.

Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

2 is a schematic view showing a schematic configuration of the present invention, and FIGS. 3 and 4 are explanatory views of the operating state of the present invention, and the driving angle of the reflection shade is narrowed and driven by forward rotation of the driving motor. The operation explanatory diagram showing the installation angle (reflection angle) of the reflection shade is widened by rotating the motor in reverse. FIGS. 5 and 6 are partial excerpts of the reflection shade of the present invention, with a narrow reflection angle and a wide reflection angle. Is an operation explanatory diagram.

As shown in the drawing, the drive motor 2 which can be rotated forward and backward is fixedly installed by controlling the switching switch 9 inside the body 1.

In the front of the drive motor 2, the slide holder 3 which has the spiral part 31 in the inner diameter part and the front opening is integrated with the rotation motor shaft 21, and is comprised.

In the slide holder 3 which is rotated forward and reverse, the socket holder 4 having the spiral portion 31 and the corresponding spiral portion 41 in the outer diameter portion thereof can be moved in and out by screwing means. It is inserted.

In addition, the front of the socket holder 4 is provided with a socket 6 on which the bulb 5 is mounted, and a reflection shade 7 which can be folded concentrically on the outer end is provided.

The reflection shade 7 basically takes the form of a fallopian tube of an all-optical narrowing tube, and is composed of a combination that overlaps into a plurality of equal parts in the longitudinal direction, and an axial pin 71 and a guide hole 72 are formed at each corresponding portion to form mutual and flowable materials. It is composed of fastening.

In the drawings, reference numeral 8 denotes a light transmission window, 10 a power switch, 11 a circuit board, 12 and 12 'are brackets for fixing the driving motor 2, and 13 are for mounting the light body 1 to the main body of the apparatus. It is a mounting part.

Referring to the effect of the present invention with such a configuration as follows.

The body 1 is mounted on the contact portion (not shown) of the camcorder via the mounting portion 13 so that the power switch 10 is turned on to light the light bulb 5 so that the subject can be projected.

In this state, in order to adjust the reflection angle of the reflector 7 to suit the size and distance of the subject, the slide holder is operated by selectively rotating the drive motor 2 by rotating the switching switch 9. (3) is rotated forward and reverse, so that the socket holder (4) inserted by the screwing means is moved forward or backward.

Accordingly, the reflection shade 7 installed in front of the socket holder 4 is opened or collapsed to allow the variable reflection of the light reflection angle.

That is, in the case where the distance from the subject is far, when the driving motor 2 is rotated forward (clockwise) by the switching switch 9 and the slide holder 3 is rotated forward, the socket holder 4 has a spiral portion. The backward movement is performed by the mutual coupling action of (31) and (41). As shown in FIGS. 3 and 5, the reflection angle (installation angle) of the reflection shade 7 becomes narrow.

Therefore, the rear portion of the reflector 7 is retracted and a result of a slight backward movement is achieved to achieve a reflection angle capable of sufficiently illuminating the subject.

On the other hand, in the case where the distance to the subject is close or the size of the subject is large, when the driving motor 2 is rotated back through the changeover switch 9, the slide holder 3 is rotated counterclockwise and screwed thereto. As the socket holder 4 is moved forward, the rear portion of the reflection shade 7 is opened to widen the reflection angle (see FIGS. 4 and 6).

When the reflection angle of the reflection shade 7 is variably adjusted in the above process, the guide holes 72 between the plurality of reflection shade components constituting the reflection shade 7 are hinged to the side pins 71 so that the socket holder 4 ) The flow of the material during the retreat or retreat operation enables smooth adjustment of the reflection angle.

As described above, according to the light of the present invention, there is an advantage that the reflection angle (installation angle) of the reflection shade can be arbitrarily changed according to the size of the subject and the distance from the subject, and the appropriate brightness and the appropriate value The improvement of the lighting efficiency by emitting the reflected light is expected to have a special effect of obtaining high quality image quality.
