DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings, in which those skilled in the art can readily implement the present invention.

FIG. 1 is a block diagram showing a solar control system for a lighting apparatus according to an embodiment of the present invention, and FIG. 2 is a side view showing the outside of a control box accommodating the controller of FIG.

Referring to FIG. 1, a solar control system for a lighting apparatus according to an embodiment of the present invention includes a solar cell module 200 that generates a predetermined DC power by sunlight, A battery 400 for charging the battery 400, an illumination device 300 that is turned on and off through a DC power supplied from the battery 400, a battery 400 is charged with power supplied from the solar cell module 200 And a controller (100) for controlling the DC power supply of the battery (400) and supplying the DC power to the lighting device (300).

The controller 100 includes a solar cell controller 102 for connecting and controlling the solar cell module 200 and a charge controller 103 for charging the battery 400 with the power of the solar cell module 200, An overcharge / over-discharge protection circuit unit 104 for preventing overcharging and over-discharge of the battery 400 to protect the battery 400, a display unit 107 for displaying an operating state and data, A display control unit 105 for driving the display unit 107 in accordance with a control signal, a temperature sensor 109 for sensing temperature, a pulse width modulation A constant voltage / constant current control unit 108 for converting a DC power source of the battery 400 into a DC power source for lighting the lighting device 300 according to a PWM control signal and providing a constant voltage constant current, The battery 400 via the charging control unit 103, Discharging of the battery 400 and displays the voltage and current status of the battery 400 in real time on the LCD display window 114 of the display unit 107 through the display control unit 105 and the temperature from the temperature sensor 109 And a main control unit 101 for receiving temperature and compensating the control value.

The main control unit 101 can control lighting and blinking of the lighting device 300 according to the lighting time of the lighting device 300 set by the user.

The overcharge / over-discharge protection circuitry 104 may limit the output voltage of the battery 400 when the DC power supply of the battery 400 is below the reference charge value. That is, the overcharge / over-discharge protection circuit 104 limits the output of the battery 400 when the charged voltage of the battery 400 is equal to or lower than a reference voltage (for example, 11.7 V, 23.4 V) (For example, 12.6 V, 25.2 V), the output of the battery 400 is resumed. For example, the overcharge / over-discharge protection circuitry 104 may prevent the overcharging / over-discharge protection circuitry 104 from supplying power to the lighting device 300 when the battery 400 is in a low voltage load disconnect (LVD) And resumes the power supply when the voltage of the battery 400 rises to 12.6 V or more.

The constant voltage / constant current controller 108 controls the constant voltage / constant current controller 108 to generate a high voltage (for example, a constant voltage) for lighting the illumination device 300 when the voltage output from the battery 400 is low (for example, 10V to 14.3V 14.4 V (14.6 V)). For example, the constant voltage / constant current control unit 108 may increase the voltage of the solar cell module 200 to 14 V even when the voltage of the solar cell module 200 is 10 V, thereby maximizing the charging.

The battery 400 may include a sealed battery and a sealed / flooded type battery. The main controller 101 may charge the power of the solar cell module 200 by selecting either the sealed battery or the liquid replenishment battery. The liquid-replenishing battery requires more active charging to prevent stratification, and the sealed battery requires a more elaborate charging in order to prevent the generation of gas. For example, when charging a 12 volt liquid replenishment battery, the constant charge voltage setting for the controller 100 may be 14.6 V and for a hermetic battery 14.4 V.

The main controller 101 controls the temperature sensor 109 to shut off and recover the system operation at a specific temperature, and can automatically turn on / off at a specific time using the timer 111. Accordingly, the main control unit 101 controls the battery 400 so that the battery 400 can be optimally charged within a range of -30 mV / ° C to -60 mV / ° C. This correction is intended to match the charge of the battery 400 to the change of the electrochemical characteristics of the battery 400. [ Accordingly, it may be very advantageous to charge and manage the battery 400 and the controller 100 in a similar or identical environment. The timer 111 is a device for turning on or blinking the illumination device 300 for a predetermined time, and may be included in the main control unit 101.

Also, a plurality of the controllers 100 may be provided and connected in parallel. In this case, a separate blocking diode is not required. At this time, it is not preferable that each controller should be connected to the independent and separated solar cell module 200 and the output, and to connect the solar input or output exceeding the rated capacity of the individual controller.

The controller 100 may be received within the control box 112. The controller 100 may be housed in the control box 112 by mounting each component on a single printed circuit board (not shown) or on a printed circuit board.

At least one selection input button 113 connected to the controller 100 and capable of driving the respective components of the controller 100 is connected to the outside of the control box 112. The solar battery module 200, And at least one connector terminal for connection with the lighting device 300 may be formed. That is, the selection input button 113 includes a first controller setting switch 113a, a second controller setting switch 113b, etc., and the connector terminal 115 A battery connection terminal (i.e., a controller power supply) 115a, a solar cell module connection terminal 115b, a load connection terminal (i.e., a lighting device connection terminal) 115c, and the like.

In order to compensate the impact resistance and strength of the control box 112, the control box 112 is made of a rubber composition containing 45 to 96.5% by weight of a polypropylene resin, 3 to 45% by weight of a rubber component and / or an inorganic additive, To 10.0% by weight of the polypropylene resin composition.

The polypropylene resin may be at least one selected from the group consisting of a propylene homopolymer, a propylene random copolymer and a propylene-ethylene block copolymer. The melt index of the polypropylene resin is not particularly limited, but is preferably 1 to 60 g / 10 min. The content of the polypropylene resin may be 45 to 96.5% by weight. If the content of the polypropylene resin is less than 45 wt%, processing is difficult. If the content of the polypropylene resin is more than 96.5 wt%, the content of other components becomes too small to exhibit its function.

In addition, the resin composition contains either or both of a rubber component and an inorganic additive to improve impact resistance and rigidity. The rubber component may be at least one member selected from the group consisting of an ethylene alpha olefin copolymer rubber and a styrene thermoplastic elastomer. Preferably, the rubber component is an ethylene-alpha -olefin copolymer containing ethylene and an alpha -olefin having 4 to 12 carbon atoms, Olefin random copolymer rubber may be used. The? -Olefin of the random copolymer may be, for example, 1-butene, 1-pentene, 1-hexene, 1-heptene, Decene, undecene or dodecene, and preferably 1-butene, 1-hexene, and 1-octene. The ethylene-? -Olefin random copolymer rubber may be used in combination of two or more ethylene-? -Olefin random copolymer rubbers. The inorganic additive may be at least one selected from the group consisting of calcium carbonate, barium sulfate, mica, talc, and glass fiber, and talc may be preferably used. The content of the rubber component and / or the inorganic additive may be 3 to 45% by weight based on the total composition. When the content is less than 3% by weight, the impact relaxation effect or the stiffness complementing effect is insignificant. When the content is more than 45% by weight, the workability is undesirably decreased.

Further, the polypropylene resin composition includes a nonionic surfactant whose boiling point or flash point is lower than the processing temperature of the polypropylene resin composition. Here, the nonionic surfactant is a polymeric nonionic surfactant synthesized by block polymerization or graft polymerization of a hydrophobic monomer and a hydrophilic monomer as a surfactant which dissolves in water without being ionized. There are several non-dissociated hydrophilic groups such as hydroxyl group (-OH) and ether (-O-), and the number of moles of oxyethylene added by adding ethylene oxide to higher alcohol, alkylphenol and fatty acid, respectively, Can be adjusted. The nonionic surfactant may be at least one selected from the group consisting of polyoxyethylene alkyl ethers, polyoxyethylene fatty acid esters, polyoxyethylene alkyl phenyl ethers, sorbitan fatty acid esters, polyoxyethyl sorbitan fatty acid esters and sucrose fatty acid esters. Can be used. Such a nonionic surfactant has a boiling point (about 90 to 100 ° C) which is much lower than the processing temperature of the polypropylene resin composition, so that gas or bubbles are produced during processing. As a result, sub-micro-sized pores are formed in the polypropylene resin matrix, so that the impact resistance and scratch resistance of the polypropylene resin composition can be improved. The content of the nonionic surfactant is in the range of 0.5-10.0 wt%, preferably 1.0-5.0 wt%, based on the total composition. When the content is less than 0.5% by weight, the impact resistance improving effect is not exhibited. When the content is more than 10.0% by weight, the rigidity is excessively decreased, which is not preferable.

The operation of the controller 100 of the solar control system for a lighting apparatus according to the present invention will now be described.

First, a user displays a setting screen on the display unit 107 through a selection input button 113 provided outside the control box 112 shown in FIG. 2, and the user selects a setting menu and performs a procedure of the menu do. For example, the over-discharge voltage setting is selected to set the over-discharge voltage, the rated current setting is selected to set the rated current value, the operation time is selected to set the illumination operation time, Can be displayed through the display unit 107. In the embodiment of the present invention, the output current is set to 10 A to drive the lighting device 300, and the driving time can be arbitrarily set to 1 to 8 hours on, 1 to 4 hours off, 1 to 4 hours on / off.

When the setting is completed, the power input of the solar cell module 200 is checked and if it is normal, charging of the battery 400 is controlled through the charge control unit 103 and the charged state is displayed on the LCD display window 114 of the display unit 107. Also, overcharge / overdischarge of the battery 400 is prevented through the overcharge / over-discharge protection circuit portion 104. [ The overcharge / over-discharge protection circuit unit 104 cuts off the output of the battery 400 and protects the battery 400 when the voltage of the battery 400 drops below the set voltage.

When the charging is completed, the current time is checked, and the current is outputted as a set constant current value at the time of turning on, the lighting device 300 is turned on, and the output voltage and the operating state are displayed on the display unit 107. When the set off time is reached, the output voltage is cut off.

On the other hand, when the operator inputs the selection input button 113, the stored data is displayed on the display unit 107. In the temperature compensation procedure, when the temperature is sensed through the temperature sensor 109, the temperature is compensated for each control value, The battery 400 is kept warm to compensate for the temperature of the battery 400 by a heating means such as a heater for a predetermined period of time.

The operation time of the illumination device 300 and the power consumption of the lighting device 300, the battery charging voltage, the battery discharge voltage, the charging of the solar cell module 200, Current state, etc., can be stored in the memory unit 106 as data, and the accumulated data or real time data can be confirmed through the display unit 107. [ The operation time of the illumination device 300 can be set from after sunset until sunrise, more specifically, 0 to 10 hours after sunset and 1 to 2 hours before sunrise. On the other hand, data over 30 days can be stored for a predetermined period (for example, one year) appropriately in accordance with the storage capacity of the memory unit 106 as an average value in units of one month, To the external server 500 and print the same.

The controller 100 can also be applied to a controller SB capable of charging solar light and controlling the load of a general electrical apparatus and a controller SBL capable of controlling the load of the solar charger and the lighting apparatus 300 Examples of such applications are shown in Table 1 below.

Meanwhile, since the perfume material having the function of treating respiratory diseases is coated on the periphery of the control box 112 of the present invention, it is effective for restoring the user's fatigue and improving the health.

The functional oil may be mixed with 95 to 97% by weight of a perfume, 3 to 5% by weight of a functional oil, 30% by weight of a lavender spike, 30% by weight of a lime- %, Manuka 20% by weight, and Inula 20% by weight.

It is preferable that the functional oil is mixed in an amount of 3 to 5% by weight based on the perfume. If the mixing ratio of the functional oil is less than 3% by weight, the effect is insignificant. If the mixing ratio of the functional oil exceeds 3 to 5% by weight, the function is not greatly improved, but the manufacturing cost is greatly increased.
