Embodiment approach

[0026] Below, use Figure 1 to Figure 2B The strobe device according to the embodiment of the present invention will be described.

[0027] figure 1 It is a schematic perspective view of the strobe device according to Embodiment 1 of the present invention. Figure 2A is a schematic front view of the strobe device according to this embodiment. Figure 2B yes Figure 2A Cutaway view of line 2B-2B of the strobe device.

[0028] Such as figure 1 As shown, the strobe device 1 of this embodiment at least includes a flash discharge tube 2 , a reflector 3 , and a trigger circuit 6 , and the flash discharge tube 2 is fixed on the reflector 3 via a fixing portion 5 . The trigger circuit 6 applies a trigger voltage to the flash discharge tube 2 via the reflector 3 . Furthermore, reflector 3 has a shape described in detail below, accommodates flash discharge tube 2 , and reflects light generated from flash discharge tube 2 .

[0029] In addition, the flash discharge tube 2 includes...

Abstract

This strobe device comprises: a cylindrical flash light discharge tube; a reflection umbrella that reflects light from the flash light discharge tube; a trigger circuit that applies a trigger voltage to the reflection umbrella; and a conductive contact section that comes in contact with at least either the flash light discharge tube or the reflection umbrella, in at least the other of either the flash light discharge tube or the reflection umbrella. The conductive contact section is arranged along the axial center direction of the flash light discharge tube. As a result, a strobe device generating a stable brightness can be achieved.

Description

technical field [0001] The invention relates to a stroboscopic device which applies a trigger voltage to a flash discharge tube through a reflector to make it emit light. Background technique [0002] Conventionally, there are strobe devices that are integrally mounted on devices such as digital cameras and mobile phones, or strobe devices that are installed later on devices. These strobe devices include: a rod-shaped flash discharge tube; and a reflector that reflects light emitted from the flash discharge tube toward a subject. [0003] In general, the above-mentioned flash discharge tube includes electrode terminals sealed to both ends of a cylindrical glass tube extending in one direction as a longitudinal direction, and a glass tube filled with a rare gas. [0004] In addition, the flash discharge tube emits light by exciting the rare gas inside the glass tube by applying a trigger voltage to the outer periphery of the glass tube while supplying electric power to the e...
