ター４は装飾的機能も発揮する。That is, the light (reflected light) of the light bulb 1 once reflected by the reflecting concave mirror 2 is not disturbed (that is, without reducing the illuminance of the light for illuminating a distant place) and directly forward from the light bulb 1. A direct light mitigation filter 4 is interposed between the reflective concave mirror 2 and the outer transparent wall 3 so that the direct light exiting through the filter passes therethrough. Specifically, as the filter 4,
Translucent plastic, translucent glass, transparent colored plastic (glass), or the like is used. This filter 4 also performs a decorative function.

い程度に外部に光が照射される。A range A in FIG. 3 indicates a range in which the direct light of the bulb 1 reaches the outside. Further, the annular range B in FIG.
Indicates the range in which the reflected light reaches the outside. As described above, of the light emitted from the light bulb 1, only the direct light passes through the direct light mitigation filter 4, and the reflected light does not pass through the filter 4, so that the light bulb 1 is not directly seen from the outside and is dazzling. Light is radiated to the outside to the extent that it is not.

できる。FIG. 4 shows a second embodiment. A curved plate-like filter 4 is provided via a supporting portion 5 projecting from the reflecting concave mirror 2. Of the light emitted from the bulb 1,
Only the direct light passes through the direct light mitigation filter 4 (reflected light does not pass through the filter 4), and the light does not directly look at the bulb 1 from the outside, but is irradiated to the outside to the extent that it is not dazzling. Then, the reflected light does not pass through the filter 4,
It is possible to irradiate a distant place without reducing the condensing illuminance without attenuation.

Is directly provided with a filter 4 for reducing direct light. Of the light emitted from the light bulb 1, only the direct light passes through the direct light mitigation filter 4 (reflected light does not pass through the filter 4), and the light bulb 1 is not directly viewed from the outside, and is not dazzled. Is irradiated with light. Also in this case, the reflected light does not pass through the filter 4 and is not attenuated.
Irradiation can be performed without lowering the collected illuminance.

い。The holding cap 12 is provided with small windows 13 at a predetermined pitch in the circumferential direction, so that light partially transmitted through the outer transparent wall 3 itself is radiated radially outward of the lamp. The light can be emitted. In addition, the present invention is design-modifiable, and for example, the whole may be composed of a lamp other than a flashlight.

ー４が装飾的機能も発揮するものである。There is no fear that the light source of the light bulb 1 is directly viewed from the outside, and the eyes can be prevented from being unexpectedly exposed to direct light. In this manner, it is possible to prevent the eyes from being damaged when viewed from a close distance. In particular, since the light source (lamp) has recently increased in illuminance, it can be said that this is a very effective invention. The reflected light does not pass through the filter 4 and does not attenuate.
Irradiation can be performed without lowering the collected illuminance. Further, the filter 4 also exerts a decorative function.
