Abstract: PURPOSE:To prevent noise and improve safety in case when a user comes into contact with a side plate by a method wherein a plurality of small holes are provided in the side plate of a burner box positioned at an upstream side of a first pressure uniforming plate and a second pressure uniforming plate. CONSTITUTION:A plurality of small holes 16 are positioned at a lower part of a front side plate 4a of a burner box 4 lower than a first pressure uniformizing plate 14 and a second pressure uniforming plate 15 in a lateral direction. Due to this fact, in case a gas combustion device is operated, a part of the combustion air discharged from a blower 7 flows from the plurality of small holes 16 into a space A between a front side plate 4a of a burner box 4 and a front plate 2a of an outer box 2 in an upward direction. At this time, heat of the front side plate 2a is removed by air flowing in the space A, discharged from an air opening 17 to a surrounding atmosphere. An increasing of temperature of substantial entire surface of the front side plate 2a can be restricted without arranging any thermal insulation material between the front side plate 2a and the front side plate 4a. As a result, even if the user comes into contacting the front side plate 2a, the user can avoid a burn. Since a vibratory pressure wave generated with the burner box 4 is released from the small holes 16 into the space A, it is also possible to prevent any noise of a gas combustion device generated by the vibratory pressure means.

As to the light reflected by the reflection umbrella 2 out of the light from the light emitting tube 1, since the reflector positioned at the back of the tube 1 is in the concave shape which has condensability in the longitudinal direction of the tube, the light is more converged in the longitudinal direction of the tube than a conventional stroboscope in which the light is converged only by a reflecting plate and a Fresnel lens arranged on the side in the longitudinal direction of the light emitting tube, because the light is additionally converged by the reflector. Thus, the converging efficiency in the longitudinal direction of the light emitting tube is improved.
