Description

  The present invention relates to a strobe light emitting device that reduces the number of parts of a light emitting mechanism by providing a side reflecting portion of a light emitting mechanism used for a light emitting unit of a strobe inside an optical system casing.

  A general strobe that is mechanically and electrically coupled to the camera and flashes in synchronization with the operation of the camera is far from the camera's built-in strobe and the camera, and is synchronized with the light of the camera. So-called external strobes (slave strobes) that are flushed by using various structures adopt various structures, but the strobe body adopting a structure in which the housing can be bent in the middle has one optical system housing. It is configured to emit light in conjunction with the camera function and house a battery and a capacitor inside.

  The other is an interface function casing, and the interface function casing is built in by electrically connecting a battery, a microcomputer, a booster circuit, an interface circuit, a sensor, and the like. After all, the strobe body is composed of an optical system housing and an interface function mechanism.

  A conventional strobe optical system housing includes a reflecting plate, a discharge tube, and a side reflecting section with a reflecting function. However, in this case, the number of parts increases, and in particular, the side reflecting section is integrated with the optical system casing. If it can be constructed, the number of parts of the light emitting mechanism is small and the manufacture is easy, and the convenience of being able to easily configure the side reflecting portion is accompanied with the production of the optical system casing.

Patent Document 1 shows a reflecting mirror, but does not consider a side reflecting portion but considers a material, and does not use a strobe optical system casing.
FIG. 1 also shows a conventional reflecting mechanism. The light emission of the discharge tube 21 is made up of a reflecting plate 22 and a side reflecting plate 23 formed integrally with the reflecting plate 22 and integrated with a strobe housing. The structure formed automatically is not adopted.

  An object of the present invention is to provide a discharge tube, a reflecting plate, and a side reflection portion that constitute a light emission mechanism of a strobe, and the side reflection portion is separated from the light emission mechanism, and is provided on a side portion in an optical system housing. It can be easily formed as the system casing is manufactured, thereby reducing the number of parts of the light emitting mechanism and ensuring the ease of manufacturing.

  Means for solving the problems of the present invention are: a strobe body incorporating a function of an external strobe, an optical system housing incorporating a light emitting mechanism of the strobe body, and a side of the light emitting mechanism provided inside the housing. A side reflection part corresponding to reflection, a discharge tube provided between the side reflection parts and emitting light as necessary, and the light emission of the discharge tube is reflected by the side reflection part so as to wrap the back part of the discharge tube The side reflection portion is provided separately from the reflection plate and provided inside the optical system casing.

  According to the present invention, among the light emitting mechanisms, the reflector and the side reflecting portion of the side reflection are provided inside the optical system casing, so that the light emitting mechanism can be easily manufactured and managed, and the optical system The effect that a side reflection part can be formed with the manufacture of a housing | casing arises.

Hereinafter, a strobe light emitting device according to an embodiment of the present invention will be described with reference to FIG. 2. FIG. 2 is a perspective view of the strobe body.
First, 11 is a strobe body. This strobe body 11 mainly has an interface function housing 1 having an interface function between the camera and the strobe and a structure in which a battery is built in a battery housing lid, and a discharge tube 2 inside. Etc. and an optical system housing 3 having a plastic Fresnel lens 4 mounted on the front surface.

  That is, the condenser and the light emitting mechanism are accommodated in the optical system housing 3. The light emitting mechanism is mechanically installed at the side reflecting portion 7 provided at the inner side portion of the side portion 6 of the optical system casing at both ends of the discharge tube 2 so that the discharge tube 2 does not fall off. A reflection plate 9 is disposed on the back of the discharge tube 2 so as to wrap the discharge tube 2, and the side reflection portion 7 and the reflection plate 9 optically reflect light emitted from the discharge tube 2 forward.

  Next, the interface function case 1 includes a battery, a microcomputer, a booster circuit, an interface circuit, and a sensor. The optical system case 3 and the interface function case 1 can be bent by the rotation of the arrow A at the center. The structure unit 5 is combined.

  Of course, the side reflecting portion 7 is adjusted in advance so as to mechanically coincide with the reflecting plate 9, and the side reflecting portion 7 of the optical system casing 3 is easily coated with a light emitting paint. And the side reflection part 7 can be obtained, without requiring components.

Thereby, the light emission mechanism of the strobe can be simplified, and the side reflection portion 7 can be obtained integrally with the optical system housing 3. Further, the side reflector 23 of the conventional strobe light emitting mechanism is not necessary, and the manufacture is facilitated.
The side reflecting portion 7 may be provided with a slight gradient in order to obtain the efficiency of reflecting the light from the discharge tube 2 forward. In this case, the side reflecting portion 7 can be formed at the same time when the optical system housing 3 is manufactured.

  As described above, since the side reflection portion 7 is provided inside the side portion 6 of the optical system casing, the reflection film may be continuously applied to the side reflection section 7 when the optical system casing 3 is manufactured, or a paint is applied. However, industrial use has great potential and is expected to spread.

It is a perspective view of the conventional light emission mechanism. The perspective view of the light emission part apparatus of the strobe concerning one Example of this invention.
