JPH11295637A - Natural light transmission system by plastic optical cable - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide a natural light transmission system capable of coping with even the time of weak sunlight such as early in the morning, at night, on cloudy days, or in raining or snowing by using a low-cost optical cable immune to bending force. SOLUTION: This natural light transmission system is provided with a condenser 2 connected to a plastic optical cable 1, a motor 4 interlocked with a sunlight tracking driving frame 3 of the condenser, a solar power generator 6 and storage battery 7 as the motive power source of an intermittent hood wiper 5 of the condenser. Besides, at the time of weak sunlight such as early in the morning, at night, on cloudy days, or in raining or snowing, a sensor 8 is operated and spot light 11 is automatically radiated or turned on/off toward the condenser 2 by existent electric power 9 or power generation 10 for private use.

Description

DETAILED DESCRIPTION OF THE INVENTION

Industrial application: indoor lighting with plastic optical cable using sunlight, indoor vegetable garden, indoor sunbathing, aquarium / appreciation fish tank, phytoplankton increase, activation of seaweed bed creation, prevention of global warming by carbon dioxide absorption Measures ・ Used to prevent red tide by using nutrients and to increase fishery resources.

2. Description of the Related Art Hitherto, indoor lighting, indoor vegetable gardens, indoor sunbathing, aquariums and appreciation fish tanks have been used for indoor lighting with an optical fiber cable using sunlight, but the cost of the optical fiber cable itself is extremely high, and it is bent. Because of its weakness, the range of use was limited, and no measures were taken when sunlight was weak such as early morning, night, cloudy weather, rain, and snow. Until now, the sensor used light to track the sunlight using a sensor, collect the light, and transmit the light to a designated location via a fiber cable.

[0003] Problems to be solved by the invention [0004] To cope with the high cost of optical fiber cables utilizing sunlight in a room or the like, a low-cost optical cable must be adopted. Use in the early morning, at night, cloudy weather, rain, snow, etc., to respond to weak light, and reduce the power cost of collecting light by tracking the sunlight with a sensor using a concentrator. It is.

Means for Solving the Problems Since the cost of conventional optical fiber cables using sunlight in a room is high, low cost is realized by replacing this with a low-cost plastic optical cable using sunlight. did. In addition, plastic optical cables that use sunlight have the characteristic of being extremely resistant to bending. In addition, using a solar system, it will be used as a power source for a solar tracking drive of the concentrator and a dust removal wiper for the hood. In addition, depending on the purpose of use, in the early morning, at night, cloudy weather, rain, snow, etc.
An artificial lighting system was used in which a spotlight from existing power or private power generation automatically illuminated and flashed.

[0005] Even if a plastic optical cable using low-cost sunlight is used, indoor lighting, indoor vegetable gardens, indoor sunbathing, aquariums and appreciation fish tanks can be sufficiently replaced by fiber-optic cables using high-cost sunlight. Is done. Plastic optical cables using low-cost sunlight
It is extremely strong in bending force, and can be used without affecting the connection of cut optical cables. In the past, the concentrator tracked the sunlight using a sensor and collected the light, and transmitted the light to a designated location using a fiber cable. However, the solar tracking drive of the concentrator was performed using a solar system. As a power source for the intermittent wiper for removing dust from the machine and the hood, the cost is reduced.
Furthermore, depending on the intended use, early morning, night, cloudy weather, rain,
Reduces power consumption in factories, offices, stores, buildings, and homes by using an artificial lighting system that automatically illuminates and flashes spotlights generated by existing power or private power generation in response to weak sunlight such as snow.・ The system has been widely used for energy conservation measures.

[0006] A light collector (2) connected to a plastic optical cable (1), a driving device (4) interlocked with a solar tracking drive frame (3) of the light collector, and a hood intermittent wiper of the light collector ( A lighting transmission system using an optical cable, wherein a solar power generator (6) and a storage battery (7) are installed as a power source of 5). In addition, the sensor (8) works when the sunlight is weak in the early morning, night, cloudy weather, rain, snow, etc., and the spotlight (search) using the existing power (9) or private power generation (10) toward the concentrator (2) A lighting transmission system using a plastic optical cable, wherein (11) automatically illuminates and flashes.

Advantageous Effects of the Invention The plastic optical cable using the low-cost sunlight of the present invention allows indoor lighting, indoor vegetable gardens, indoor sunbathing, aquariums and appreciation fish tanks using fiber optic cables using the conventional high-cost sunlight. Since the use of solar energy has been sufficiently replaced, a foundation widely used as an energy saving system using solar light has been established.

[0008] A low-cost plastic optical cable utilizing sunlight is extremely resistant to bending force and can be used without being affected by the connection of the cut optical cable, and has excellent characteristics in this respect, so that handling is simplified. In addition, construction costs are reduced and installation costs are reduced.

[0009] Until now, the concentrator tracks the sunlight using a sensor and collects light by using a sensor, and transmits the light to a designated place via a fiber cable. In the present invention, the concentrator uses a solar system. Solar tracking drive,
As a power source for intermittent wipers for removing garbage from the hood, the solar system and concentrator are separated, and the fiber cable is extended to provide oil, coal, natural gas,
A low-cost lighting system that does not catch fire or fire at mines, petroleum stations, factories, etc. can be created.

[0010] Depending on the purpose of use, early morning, night, cloudy,
Power consumption in factories, offices, stores, buildings, and ordinary households by using an artificial lighting system that automatically illuminates and flashes spotlights generated by existing power or private power generation in response to weak sunlight such as rain and snow It is a system that is widely used for reduction and energy saving measures.
