Description

[Technical field]

[0001] This invention relates to an LED solar powered outdoor light that employs high level solar cells (potentially generating electricity from sources other than sunlight). [Background technology]

[0002] Electricity is a general term for various physical phenomena, the most common of which are static electricity and lightning. Electricity was already invented in the 1700s, and today people take electricity for granted on a daily basis. However, as is well known, generating electricity requires a huge amount of money, time, and equipment.

[0003] Therefore, electricity is an essential requirement for human survival, and for this reason, various power generation methods have been developed up to the present, such as hydroelectric power generation devices, nuclear power generation, solar power generation, wind power generation, geothermal power generation, biomass power generation, vibration power generation, wave power generation, etc., and new power generation methods will likely continue to be considered in the future. Among these, solar power generation is superior to the others in terms of ease of handling, simple configuration, efficiency, installation, and ease of combination with other devices.

[0004] Regarding traffic signals in Japan, it is said that there are approximately 2.26 million traffic signals in the country, of which approximately 1.26 million are for vehicles and 1 million are for pedestrians, and the electricity bill is 890 million yen per month, or just under 10 billion yen per year.

[0005] In other words, if the costs for vehicles and pedestrians are combined, the total amount comes to a considerable amount, and as such, traffic signals in Japan involve an enormous financial burden, and it is well known that when a power outage occurs, it causes chaos in social life.

[0006] Considering the above circumstances, there is a need for outdoor lighting equipment or traffic signal lighting equipment that will not cause power outages and will not impede social activities no matter what the circumstances. For example, Patent Document 1 proposes an LED power-generating lighting device that is installed inside a triangular prism with the light-receiving surface of the solar panel facing inward.

[0007] In the case of the LED power-generating lighting device of Patent Document 1, in order to generate power efficiently with a small number of LED light sources, it is necessary to enlarge the light-receiving surface by changing the shape of the solar panel, so the solar panel is shaped like a triangular prism or other cylinder with the light-receiving surface facing inwards, and an LED light source is placed inside the cylinder. Also, the light from this LED light source is irradiated onto the entire light-receiving surface of the solar panel inside the cylinder, functioning as a power generating device.

[0008] However, in the case of the LED-powered lighting device in Patent Document 1, the improvement of power generation efficiency was mainly achieved by changing the shape of the solar panel, and it is not suitable to use it as a power source for devices that require continuous, stable operation over a long period of time, such as traffic signals and outdoor lighting devices, and it is believed that no equipment with such a function exists.

[0009] [Patent Document 1] Utility Model Registration No. 3195799 Summary of the Invention [Problem to be solved by the invention]

[0010] In consideration of the above circumstances, the present invention provides an LED solar power generation system that is functionally independent of wind, atomic power, etc., by configuring power generation and charging in a circular manner, and that does not cause power outages for outdoor lights and other lights for various purposes in facilities, regardless of the circumstances, is easy to install, and can ensure the continuous operation of the light-emitting power generation means. [Means for solving the problem]

[0011] The LED solar powered outdoor light of the present invention comprises an LED light supplied with power from first to third chargers, a cell that receives light from the LED light and generates electricity, and the electricity generated from the cell is supplied to the first to third chargers and a load via first to third switches managed by a charger control unit, and when the batteries of the first to third chargers run out, the charger control unit works in cooperation with a first spare charger control unit and a second spare charger control unit to supply power to the first to third chargers and the load from the first spare charger or the second spare charger via the first auxiliary switch or the second auxiliary switch, and the first spare charger is charged by a spare charger cell, and the second spare charger is also charged by a spare charger cell. Effect of the Invention

[0012] According to claim 1, a power-generating lighting system can be provided that can ensure continuous operation of the power generation means, with minimal power outages no matter what the circumstances, and that can emit light in a quasi-circulating manner without relying on hydroelectric power generation equipment, nuclear power generation, solar power generation, wind power generation, geothermal power generation, biomass power generation, vibration power generation, wave power generation, wind power, etc. In addition, since the overall structure is simple, it can be installed anywhere, and since the power generation cells are highly efficient, it can be used continuously, and an LED solar power generation outdoor light that can be used as a simple lighting device can be provided. [Brief description of the drawings]

[0013] [Figure 1] 1 is a system structure diagram of a power generating lighting system according to embodiment 1 of the present invention. [Diagram 2] FIG. 2 is a schematic diagram of the street light installed in FIG. 1. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0014] The objective of the present invention is to provide a power-generating lighting system that is not particularly dependent on sunlight, wind, nuclear power, etc., and that can minimize the occurrence of power outages no matter what situation occurs and can ensure the permanent operation of LEDs in, for example, lighting fixtures, street lights, and traffic lights, by configuring an outdoor lighting facility that includes LED lights to which power is supplied from first to third chargers, cells that generate power by receiving light from the LED lights, first to third chargers to which the electricity generated from the cells is supplied via first to third switches managed by a charger control unit, and a load, and when the batteries of the first to third chargers run out, the charger control unit works in cooperation with a first spare charger control unit and a second spare charger control unit, and power is supplied from the first spare charger or the second spare charger to the first to third chargers and the load via the first auxiliary switch or the second auxiliary switch, and the first spare charger is charged by the spare charger cell, and the second spare charger is also charged by the spare charger cell, and each of the above-mentioned requirements is met. EXAMPLES

[0015] An embodiment of the present invention will be described in detail below with reference to FIGS. EXAMPLES

[0016] FIG. 1 shows the power-generating lighting system of FIG. 2 according to the first embodiment of the present invention, which is installed as an outdoor light outdoors, and will be described below. First, the power-generating lighting system of Figure 2 does not depend solely on sunlight, wind, atomic power, etc., and can provide a system that will not experience power outages no matter what situation occurs, ensuring the permanent operation of lighting, traffic lights, etc.

[0017] 2 denotes LED lights to which power is supplied from the first to third chargers 11, 12, and 13, and these are arranged in parallel in a plane. Cells 14 are arranged between these LED lights to receive the light of the LED lights L. Electricity generated from the cells 14 is supplied to the first to third chargers 11, 12, and 13 and the load L via switches SW1, SW2, and SW3 (any of the switches) that are managed by a charging control unit 15 and selected to be on.

[0018] In this case, the cells 14 and the LED lights are separately provided as a solar cell device 30 and an LED light device 31 shown in Fig. 2. In addition, a part of the cells 14 is also separately provided as a first cell 22 and a second cell 23, which will be described later. Therefore, the LED light device 31 and the solar cell device 30 are configured as shown in Fig. 1.

[0019] When the first to third chargers 11, 12, 13 run out of charge capacity, the charging control unit 15 cooperates with the first spare charger control unit 16 and the second spare charge control unit 17, and power is supplied to the first to third chargers 11, 12, 13 and the load WL from the first spare charger 20 or the second spare charger 21 via the first auxiliary switch 18 or the second auxiliary switch 19. This prevents a situation in which power cannot be supplied to the load even if a sudden problem occurs with the load WL, and allows the user to enjoy continuous lighting without worry.

[0020] This is because the first and second spare chargers are provided with spare charging cells 22, 23, and these spare charging cells 22, 23 are also designed to always receive light from the LED light L. In other words, the charging cells 22, 23 are provided using part of the LED light's cell 14, and the LED light L and cells 14, 22, 23 receive sunlight and continue to charge themselves, creating a so-called circulation type, which allows continuous lighting activity to be realized. [Industrial Applicability]

[0021] The LED solar powered outdoor light of this invention generates electricity using cells from the light from its own LED lights, which is then charged in a charger, and by cleverly combining this charging circuit, it is possible to constantly supply power to the load, so it can maintain power supply activity for a long period of time, and there is no risk of street lights going out.Furthermore, the structure is simple and it can be easily installed even in places where installation locations are restricted, making it an LED solar powered outdoor light with great practical effects and a simple configuration of the device itself.
