The reflector 40 has an elliptic curve in cross section.
A parabolic curve or a shape similar to these shapes,
The distal end portion 41 is opened as an irradiation opening, the base end portion 42 as a light source mounting portion is terminated, and the inner surface thereof gradually narrows from the irradiation opening toward the optical axis L (FIG. 13) behind the light source mounting portion. The reflective surface 43 is formed by In the illustrated example, not only the reflection surface 43 of the reflection plate 40 but also the non-reflection surface 44 are formed in the same shape. If the cross section of the reflection surface 43 is an elliptic curve or a parabolic curve inside the base end portion 42, an arc tube 50 is mounted at the focal point.

The reflecting plate 40 is supported and mounted such that the front end 41 of the irradiation opening is aligned with the light emitting opening 21 of the housing 20. When the arc tube 50 emits light, the emitted light is reflected by the reflection surface 43 of the reflection plate 40 and is radiated to the front end 41 of the opening. The emitted light is dispersed by the Fresnel lens 30 at an appropriate irradiation angle to irradiate a subject (not shown).

At both ends of the arc tube 50, an anode electrode 51 and a cathode electrode 52 are led out. The anode electrode 51 and the cathode electrode 52 are connected to the bottom plate 22 of the housing 20 (FIG. 1).
The metal terminal plates 53 and 54 from the light emitting circuit block 60 introduced in 3) are connected respectively.

The output of the trigger coil 64 constituting the light emitting circuit block 60 is transmitted through a trigger electrode 641 introduced from the rear of the rear plate 23 of the housing 20 to the non-reflection on the rear surface of the base end 42 of the reflector 40. Surface 44 is in contact.

The light emitting circuit block 60 is shown in FIGS.
As shown in FIG. 6, a step-up transformer 621 constituting a charge control unit 62 disposed on a mounting board 61, a trigger coil 64 constituting a high-voltage unit 63, and a medium-voltage unit 6

[0014]

By the way, the connection wiring between the output terminal 644 of the trigger coil 64 and the trigger electrode 641 is connected to another control wiring, a metal body case, another substrate, and an element. In order to prevent destruction, they must be sufficiently separated from them, and the degree of freedom in electric wiring design is low. For this reason, it was difficult to reduce the size of the light emitting circuit block 60, especially around the high voltage. In addition, in the above-mentioned electric wiring connection, connection is made via a metal terminal plate, so that the number of manufacturing steps is increased, and it has been difficult to reduce the cost.

The high-voltage component used here has a large component size, and it has been difficult to achieve both a reduction in the area of the mounting substrate 61 and a reduction in the thickness of the mounting surface.

Accordingly, the present invention has been made in view of such a problem, and an object of the present invention is to provide a flash light emitting device capable of concentrating a high-voltage portion and reducing the size and cost of a light emitting circuit block. It is the purpose.
