Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a photoelectric lamp device, and more particularly, to a method of focusing the sunlight when it is available and introducing it into a light conductor cable and introducing it into a wrinkled light conductor cable. The sunlight transmitted through the light conductor cable is radiated from the end of the light conductor cable as a light source, and when sunlight is not available, an ordinary light bulb or circle line is used as a light source. This invention relates to a photoelectric lamp device.

The present applicant has proposed various methods of concentrating sunlight using a lens or the like, introducing it into a light guide cable, and transmitting it to any desired location through the light guide cable to provide illumination. The present invention was also made as part of this, and in particular, when sunlight is available, using the sunlight as a light source,
Furthermore, when sunlight is not available, such as at night or on cloudy days, a regular light bulb or circle line can be used as a light source.

FIG. 1 is a schematic side sectional view for explaining one embodiment of the photoelectric lamp device according to the present invention, in which 1 is a light guide cable, 2 is a shade, 3 is a light bulb, and 4 and 5 are convex or A concave lens or a convex or concave Fresnel lens, 6 a photodetector, 7 a switch means, and a light conductor cable 10 whose end (not shown) is connected to a well-known sunlight collecting device, in which the light-receiving surface is arranged at the focal point of the sunlight collection lens system, and sunlight focused by the lens system is introduced. Therefore, at the time of application, when sunlight is available, the sunlight collected by the solar collector is transmitted through the light conductor cable l, and is radiated from the end face 1a of the light guide cable 1, The light is then diffused and/or focused and emitted through lenses 4 and/or 5 for illumination. On the other hand, whether or not light is being transmitted to the optical conductor cable 1 is detected by a photodetector 6. At night or on a cloudy day, when no sunlight is being transmitted or when the amount of light is low, the switch 7 is turned on. Light bulb 3
lights up. Note that the number of light bulbs 3 may be singular or plural, and in the case of multiple light bulbs, all the light bulbs may be turned on and off at the same time, but preferably, the number of light bulbs 3 may be one or more. Depending on the intensity, for example, when the transmitted sunlight is weak, it is better to turn on more light bulbs, and when it is stronger, it is better to turn on fewer light bulbs. It is preferable that each set is turned on and off in units of one set. 1) is a diagram showing an example of the photoelectric lamp device shown in FIG. The light bulb 3 is arranged symmetrically with respect to the light guide cable 1, and is arranged in a trap so as not to block the light emitted from the light guide cable 1. In addition, 8 is Kasa 2
A reflecting surface deposited on the inside of the shade 2 or a reflecting surface of a reflecting plate (not shown) provided separately from the shade 2. If the reflecting plate is composed of a reflecting plate, the reflecting plate can be moved in the vertical direction. (The illustrated state corresponds to the case where it is disposed at the upper limit position), it becomes possible to adjust the projection direction of the light emitted from the bulb 3.

In addition, instead of moving the reflector in the vertical direction, the light bulb 3 may be moved in the vertical direction or in the horizontal direction, and in that case, the reflective surface 8 is formed on the shade 2. Also, the direction of light reflected from the reflective surface 8 can be adjusted. Furthermore, if the reflective surface 8 is made of a blue reflective surface, for example, the light emitted from the light bulb 3 can be reflected as light close to natural light.

FIG. 2 (4) is a schematic side sectional view showing another embodiment of the present invention, and FIG. 2 (4) is a view of the photoelectric lamp device shown in FIG. In this embodiment, a circle line 9 is used in place of the light bulb 3 of the embodiment shown in FIG. 1, but it is also possible to use a combination of a light bulb and a circle line. It's easy to understand. In addition,
In this embodiment, it is not necessary to attach the circle line movably in the horizontal direction, and since the circle line originally emits light close to natural color, the reflective surface 8 is made a colored (blue) reflective surface. It is easy to understand that there is no need to do so. Furthermore, although FIGS. 1 and 2 show an example in which the light in the center is diffused using the concave lens 4 and the light in the periphery is focused using the convex lens 5, the present invention is not limited to the above embodiment. In some cases, but not limited to,
It is easy to understand that it may be configured with only concave lenses or convex lenses, or may have a convex lens in the center and a concave lens in the periphery.

As is clear from the above description, according to the present invention, when sunlight is available, it is illuminated by sunlight, and when sunlight is not available or when the sunlight is weak, it automatically turns on normal electric lighting. Alternatively, you can switch to a combination of electric lighting and solar lighting, so you can use sunlight most efficiently without any hassle.
