て利用できるようにしたものである。 The present applicant has made various proposals for concentrating sunlight using a lens or the like, introducing it into a light guide, and transmitting it to any desired location through the light guide to provide illumination. This invention was developed as part of this effort, and in particular, when sunlight is available, it can be used as a light source, and when sunlight is not available, such as at night or on cloudy days, it can be used as a regular electric light. This is how it was done.

る。 FIG. 1 is a configuration diagram for explaining an embodiment of the photoelectric lamp device according to the present invention, and in the figure, 1 indicates a point where sunlight collected by a well-known sunlight collecting device (not shown) is transmitted. A light conductor cable, 10 is a light bulb, 20 is a convex or concave lens, or a convex or concave Fresnel lens, and a part of the bulb wall of the light bulb 10 is provided with a reflective film 1.
1 (hatched area) is formed, but this reflective film 1
1 has a circle 12 with a diameter approximately equal to the diameter of the optical conductor cable 1, as shown in FIG.
No reflective film is applied to this circle 12 portion. Therefore, the optical conductor cable 1 is located at this circle 12.
When the end face of the light bulb is applied, sunlight transmitted through the light conductor cable 1 is introduced into the bulb 10 through the bulb wall of the bulb 10, passes through the bulb 10,
It is then diffused by a concave or convex lens 20,
Alternatively, the light may be focused or made into parallel light beams for illumination. Whether or not sunlight is being transmitted to this optical conductor cable 1 is determined by detecting the light from the optical fiber 1' branched from the optical conductor cable 1 using the CdS optical detection means 3.
0, when sunlight is being transmitted, turn off the switch 40 of the light bulb 10, and when no sunlight is being transmitted or when the sunlight is weak, turn on the switch 40, A current is passed through the filament 13 of the light bulb 10 to light the light bulb 10.

ともない等の利点がある。 Therefore, according to the present invention, when sunlight is available, it is illuminated by sunlight, and when sunlight is not available or when sunlight is weak, it automatically switches to normal electric lighting, so there is no need to worry. You can use sunlight in the most efficient way without any hassle. Also,
It is possible to introduce light from the light conductor cable into the light bulb without having to insert the light conductor cable into the light bulb, and therefore without adding any special processing to the light bulb, which adds extra cost to the production of the light bulb. It has the advantage that such problems do not occur.

[Scope of utility model registration request]

It consists of a light conductor cable through which light is transmitted, a light bulb having a filament inside, and a lens. A portion corresponding to approximately the cross-sectional area of the optical conductor cable is left unformed on the reflective surface, and the light transmitted through the optical conductor cable is transmitted through the remaining unformed portion on the reflective surface. A photoelectric lamp device, characterized in that the light is introduced into the bulb through the bulb wall of the bulb and is configured such that the light emitted through the bulb is radiated through the lens.
