The present invention relates to a lighting system using a solar cell module for generating electrical energy by receiving infinite and pollution-free solar energy.

Solar cells are semiconductor devices that convert light energy into electrical energy using the photoelectric effect. Most solar cells are composed of P-N junction diodes and the principle of operation is as follows.

First, when sunlight with energy greater than the band-gap energy of a semiconductor is incident, electrons and holes are generated. Next, the generated electrons and holes are collected by the electric field and the electrons by the N layer and holes by the P layer to generate an electromotive force in the electrons and the positive space. Finally, the current flows when the load is connected to the electrodes at both ends.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. First, in adding reference numerals to the components of each drawing, it should be noted that the same reference numerals are assigned to the same components as much as possible, even if shown on different drawings. In addition, in describing the present invention, when it is determined that the detailed description of the related well-known configuration or function may obscure the gist of the present invention, the detailed description thereof will be omitted. In addition, the following will describe a preferred embodiment of the present invention, but the technical idea of the present invention is not limited thereto and may be variously modified and modified by those skilled in the art.

First, Figure 1 is a side cross-sectional view of a lighting system using a solar cell module according to a preferred embodiment of the present invention. As shown in FIG. 1, the illumination system 1 includes a solar cell module 10, a battery 20, an illumination unit 30, a detection unit 40, a frame 50, a first entrance plate 60, and a first It consists of two entrance plates 70.

The solar cell module 10 coupled to the inside of the frame 50 having a rectangular shape is coupled to the first entrance plate 60 coupled to the front portion of the frame 50 and the rear portion of the frame 50. The solar energy incident through the second entrance plate 70 is input to generate electrical energy, and the first entrance plate 60 and the second entrance plate 70 preferably have light transmissivity.

The battery 20 coupled to the lower portion of the frame 50 is electrically connected to the solar cell module 10 to store electrical energy generated by the solar cell module 10 and is received from a remote controller (not shown). It is connected to the sensing unit 40 which is coupled to the front portion of the frame 50 for detecting the control signal to be operated and stop operation through the remote control. In addition, the sensing unit 40 may be further provided with an automatic lighting control function for transmitting a signal to the lighting unit 30 by sensing the illumination and humidity of the outside of the lighting system (1).

The lighting unit 30 coupled to the upper portion of the frame 50 is electrically connected to the battery 20 to emit light using electrical energy charged in the battery 20. The lighting unit 30 may use various light sources such as incandescent lamps, fluorescent lamps, three wavelength lamps, and LEDs, and may emit different mood lights according to a plurality of options. In addition, the lighting unit 30 may be further provided with an emotional lighting system, the emotional lighting system is a color temperature is freely adjusted to express the color temperature according to the morning, noon, sunset using a light source consisting of red, green, blue LED Say the system.

In addition, since the first incident plate 60 and the second incident plate 70 are preferably coupled to the front and rear surfaces of the frame 50, the lighting system 1 may be utilized as windows and windows.

2 is a front view of a lighting system using a solar cell module according to a preferred embodiment of the present invention. As shown in FIG. 2, the lighting system 1 represents a coupling relationship between the solar cell module 10, the battery 20, the lighting unit 30, and the sensing unit 40 coupled to the inside of the frame 50.

The most important thing in using the solar cell module 10 is to consider the system voltage. Various types of system voltages are available, but the higher the voltage, the greater the number of solar cell modules required to be combined, and thus the higher the installation cost and risks associated with high voltages. In addition, a charge controller (not shown) may be coupled between the solar cell module 10 and the battery 20.

The main function of the charge controller is to extend the life while maximizing the capacity of the battery through normal charging of the battery. The basic function of the charge controller is to prevent the reverse flow of current and to prevent overcharging. When reverse current flows from the battery to the solar cell module, the reverse current is prevented by connecting a semiconductor bipolar element called a blocking diode in series. In order to prevent the battery from being continuously applied when the battery is fully charged, the flow of current is interrupted when the battery's charging voltage reaches a certain voltage, and again when the battery's voltage falls below a certain voltage. Connect the flow of current. Such overcharge prevention control methods include an on-off method, a pulse width modulation method, and a maximum power tracking method.

The battery 20 used in the lighting system 1 is a secondary battery. Types of secondary batteries include nickel-cadmium (Ni-Cd) batteries, nickel-hydrogen (Ni-Mh) batteries, lithium-ion (Li-ion) batteries, and lead-acid (ES) batteries.

Nickel-cadmium (Ni-Cd) batteries can be manufactured at low cost and have a very stable voltage when discharged. However, their capacity is relatively small and, above all, due to the 'memory effect', they must be fully discharged to recharge efficiently. It is not preferable because it has inconvenience that can be utilized. Recently, nickel-hydrogen (Ni-Mh) batteries or lithium-ion (LI-ion) batteries that considerably improve the disadvantages of nickel-caddium (Ni-Cd) batteries may be considered. Is not.

Batteries suitable for storing the electrical energy generated by the solar cell module can be manufactured at low cost, have excellent technical completion, and have maintenance such as replenishing the electrolyte solution, especially at the end of life, among the longest used (ES) batteries. Maintenance-free sealed lead-acid (ES) batteries are suitable, which have the advantage of having a long life compared to other secondary batteries with low self-discharge rate with unnecessary, economical and most fluid temperature range.

In the case of the lighting unit 30 using the electrical energy generated by the solar cell module 10, an additional component is required depending on whether to use the DC 12V electric lighting or the AC 220V electric lighting. In the case of using DC 12V electric lighting, no special components are required, but when AC 220V electric lighting is used, an inverter (not shown) may be coupled between the battery 20 and the lighting unit 30.

Inverter is a device that converts direct current into alternating current, and the matters to be considered when selecting an inverter include application environment, electrical standard, power capacity, and internal protection device. However, in the present invention, the focus is on the automatic on / off function. It needs to be placed. This is because the inverter itself consumes a certain amount of power, which is a burden in a relatively small power-consuming system such as the present invention. Low-cost inverters usually have a manual on / off switch, which can run out of battery power if care is not taken. Therefore, most home inverters have a built-in sensing function for the auto on / off function. This should be noted as it is expressed in various ways by the manufacturer.

The sensing unit 40 is connected to the battery 20 to detect an operation and a stop signal transmitted by an infrared or RF remote controller (not shown) to enable operation and stop of the battery 20 according to the signal. .

The above description is merely illustrative of the technical idea of the present invention, and various modifications, changes, and substitutions may be made by those skilled in the art without departing from the essential characteristics of the present invention. will be.
