LED (Light Emitting Diode) devices, which are widely applied to lighting apparatuses in recent years due to low power consumption, high brightness, and long life, are generally commercialized by mounting an LED device on an epoxy printed circuit board (PCB). Such an LED lighting product is required to have various designs for controlling the heat generation because the degradation of the device itself may be accelerated due to the heat generated by the LED device, and a failure may occur in the entire system.

Up to now, it has been known that the LED device has an efficiency of about 30%. In order to obtain a higher luminous intensity, the higher the output, the higher the calorific value. In case of PCB, high heat-dissipating PCB using metal material can be applied. Typical PCBs are FR-4 substrates, which have an insulating layer made of a composite material of glass fiber and epoxy. In the FR-4 substrate, the thermal conductivity is as low as about 0.3 W / mK, The circuit uses a metal PCB composed of an insulating layer and a metal base excellent in thermal conductivity.

In this regard, Korean Patent Laid-Open No. 10-2012-0021901 (inventor: Kim Dongsoo) is a lighting device having a metal panel, which includes a metal panel coated with a nonconductive film, a conductive pattern formed on the non- There is provided an illumination device having a metal panel adapted to include a light emitting element that is attached to connect to a conductive pattern. An illumination device in which an LED device is mounted on a glass substrate according to a specific application by applying the known technology can be provided.

Korean Patent No. 10-0989766 (inventor: Park, Il-Hong) is a general glasshouse, in which two tempered glasses are spaced apart from each other to form a glasshouse as a multi-layered glass panel formed of a single panel, And a supply and recovery pipe communicating with the uppermost and lowermost multilayer glass panels are disposed in the upper and lower ends of the supply and recovery pipe, respectively, and a supply and recovery water tank is provided at the inlet and the outlet end of the supply and recovery pipe, respectively. In the upper and lower ends of each of the double-layered glass panels, the colorless antifreeze supplied through the supply pipe from the supply water tank is installed diagonally so as to circulate and discharge the internal space of each double-layer glass panel in a zigzag manner, Layer glass panel through the inlet / outlet pipe so as to communicate with each other in each column. It provides a glass greenhouse.

The comparison technique is advantageous in that the antifreeze is circulated between the glass panels of the greenhouse so that the warmth of the glass panel can be enhanced and the snow can be removed. However, the glass panel is provided with a double structure and a circulation structure and pump for circulating the antifreeze It is disadvantageous in that there is a lack of economical efficiency in that a facility such as a tank is required.

Also, due to the structure in which the antifreeze is circulated between the glass panels, it is difficult to realize a structure for ventilating the greenhouse by opening the panel.

In order to solve the above-mentioned problems, the present invention can be utilized as a lighting facility for maintaining the dimming in the greenhouse during the rainy season or the winter when the LED element is mounted on a glass substrate and used as a glass warming panel And at the same time, it can be used as illumination for plant growth at night, and the disadvantage that the heat is released to the outside due to the thermal insulation problem of glass at sunset can be solved by using the heat generated from the LED device. Also, a glass LED panel greenhouse capable of eliminating condensation and snowfall using the heat of the LED element is provided.

In addition, by providing a power drive device capable of opening and closing the panel for maintaining the temperature of the greenhouse and ventilation, it is possible to easily control the growth environment of the greenhouse by ventilating the greenhouse.

While the invention is susceptible to various modifications and alternative forms, specific embodiments thereof are shown by way of example in the drawings and will herein be described in detail. It is to be understood, however, that the invention is not to be limited to the specific embodiments, but is to be understood to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the invention, And the scope of the present invention is not limited to the following examples.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings, wherein like or corresponding elements are denoted by the same reference numerals, and redundant explanations thereof will be omitted.

1, 2 and 3, a glass LED greenhouse 1000 according to the present invention includes a greenhouse glass window 100 including an LED substrate layer 10 and a polymer dispersed liquid crystal layer 20, ≪ / RTI >

The LED substrate 10 is prepared by providing the substrate 11 made of glass and mounting the conductive pattern 12 and the LED element 13 on the substrate 11. [ Since the substrate 11 is made of glass, it is not necessary to process a separate nonconductive film. The conductive pattern 12 is formed by connecting the LED elements 13 by soldering or wire bonding to form a circuit. For example, the conductive pattern 12 may have a negative terminal and a positive terminal, The EL element 13 is connected to the EL element 13, The element 13 is operated.

The substrate 11 on which the conductive pattern 12 and the LED element 13 are mounted can be coated with the protective layer 14 after short circuit or short-circuiting of the circuit. The protective layer 14 serves as an insulating layer and may be provided to protect the conductive pattern 12. [ The protective layer may be formed by coating an epoxy-based polymer, which is a thermosetting resin, or polyvinyl acetate or urethane, which is a thermoplastic resin, with silicon. At this time, since the LED substrate 10 has a property of transmitting sunlight by acting as an outer wall of the greenhouse, it is preferable that the coating of the protective layer is made as thin as possible as long as it can protect the conductive pattern 12 . The coating layer 15 may be further provided on the upper surface of the protective layer 14. [ The coating layer 15 may be made of PC (poly-carbonate) material which is more resistant to physical shock or damage than the protective layer 14. [

Referring to FIG. 7, the polymer dispersed liquid crystal layer 20 may be bonded to the back surface of the LED substrate 10. Polymer dispersed liquid crystal (Polymer Dispersed Liquid Crystal) is generally prepared by filling a polymer dispersed liquid crystal between two electrode plates in a layer. When electricity is applied to both electrode plates, transparency of a polymer dispersed liquid crystal is changed, It is being applied to smart windows that block visibility.

The polymer dispersed liquid crystal layer 20 provided in the present invention can be used as a shielding means for controlling the transmittance of the greenhouse glass by being applied to the greenhouse glass window 100. Since the temperature inside the greenhouse can rise beyond the optimum growth range of the crop during the summer season in which the amount of solar radiation is large, the polymer dispersed liquid crystal layer 20 is operated at such a time, and the inside of the greenhouse is appropriately maintained It is possible to do.

When the LED substrate 10 and the polymer dispersed liquid crystal layer 20 are combined as described above, the protective frame 14 is fitted around the glass substrate 10 to protect the LED substrate 10 and the polymer dispersed liquid crystal layer 20, (100) that can be coupled to the ventilation window (200) of the air conditioner (1000). The LED substrate 10 may be made of general glass or made of tempered glass. However, even if tempered glass is used, the amorphous nature of the glass is strong against the pressure applied to the flat surface, and is relatively weak against side impact. Therefore, the protection frame 10a surrounds the edge of the LED substrate 10 and the polymer dispersed liquid crystal layer 20 so as to reduce the impact on the side, thereby preventing breakage and facilitating installation in the ventilation window 200 Can be provided.

At this time, the greenhouse glass window 100 may be provided with a connector 10b for supplying power to one side and the other side. The connector 10b is connected to the conductive patterns 12 and the electrodes of the liquid crystal layer (not shown) to supply power to the LED substrate 10 and the polymer dispersed liquid crystal layer 20, . At this time, since the LED substrate 10 is provided to serve as the outer wall of the greenhouse, condensation may occur from time to time depending on the condition of the indoor air. The LED element 13 and the conductive pattern 12 of the LED substrate 10 may be protected by the protective layer coated as described above but since the connector is a line protruding outward from the LED substrate 10, It may be exposed to condensation and cause disconnection. Therefore, it is preferable that the connector 10b provided for power supply to one side and the other side of the LED substrate 10 is provided as a waterproof connector. For example, it is desirable that the waterproof grade of a waterproof connector is designed to meet at least five degrees (protection from low water pressure water flowing in from all directions) under the IP (International Protection) standard.

Referring to FIG. 4, the ventilation window 200 may be provided as a project-type window in which the greenhouse glass window 100 provided as described above is tilted and opened.

The ventilation window 200 is provided as a window to which the greenhouse glass window 100 is coupled. The greenhouse glass window 100 is fixed by being hinged to both sides of the upper frame 220 of the ventilation window 200. At this time, the greenhouse glass window 100 is provided so as to be engaged with the end portion formed at the edge of the ventilation window 200 with the edge connected to the ventilation window 200 to prevent the penetration of the rainwater, (100) are hinged to each other.

One end of the opening and closing rod 110 is hinged to the lower end of the greenhouse glass window 100 hinged to the ventilation window 200. The opening and closing rod 110 passes through the lower frame 210 of the ventilation window 200, And a gear structure is formed on the outer circumferential surface of the pulley gear 211a.

At this time, the opening and closing rod 110 passes through the guide sleeve 212 fixed to the lower frame 210 and is coupled with the pulley gear 211a inside the lower frame 210, and the other end passes through the lower frame 210 . A stopper 110d may be provided at the other end of the opening and closing rod 110 to limit the operation range of the opening and closing rod 110. [

The guide sleeve 212 may be formed in a cylindrical shape having a hollow portion and may be provided such that the inner diameter of the guide sleeve 212 closely contacts the outer diameter of the opening and closing rod 110 to allow the opening and closing rod 110 to move along the hollow of the guide sleeve 212 . Accordingly, the guide sleeve 212 transmits the rotational force of the pulley gear 211a to the opening / closing rod 110, so that the opening / closing rod 110 can move up and down.

Referring to Fig. 5, the pulley gear 211a is fixed to penetrate through the driving shaft 211, and thereby the pulley gear 211a is rotated by the driving of the driving shaft 211. [ The drive shaft 211 is coupled to a drive motor m at one end to obtain a drive force for operation of the pulley gear 211a.

Referring to FIG. 6, the pulley gear 211a may be provided with a torque adjusting portion for preventing the driving force from being transmitted beyond the movable range of the opening and closing rod 110. [

The pulley gear 211a is provided with a plurality of groove-shaped slopes t which are formed at regular intervals along the inner diameter portion through which the drive shaft 211 passes. On the other hand, the outer peripheral surface of the drive shaft 211 is inserted from the outer diameter side toward the barycenter of the drive shaft 211 and is supported by an elastic member provided inside the drive shaft 211 so that one side is in close contact with the slope t, A torque adjusting ball b is provided. The torque adjusting ball b is engaged with the slope t by a predetermined force by the elastic member and is released from the slope t when the rotational force of the driving shaft 211 exceeds the striking force of the elastic member. Thereby preventing the rotational force of the shaft 211 from being transmitted to the pulley gear 211a.

According to this structure, the greenhouse glass window 100 is opened and closed by the operation of the opening and closing rod 110 and the pulley gear 211a, and even if the driving shaft 211 rotates beyond the operating range of the opening and closing rod 110, The pulley gear 211, the pulley gear 211a and the drive shaft 211 can be prevented from being damaged.

Hereinafter, the operation of the glass LED panel greenhouse having the ventilation opening / closing mechanism according to the present invention will be described.

When the power is applied to the motor m to drive the drive shaft 211, the opening and closing rod 110 engaged with the pulley gear 211a is moved up and down. As the opening and closing rod 110 moves up and down, the greenhouse glass window 100 is separated from the ventilation window 200 and opened or closed. At this time, the torque adjusting ball b that engages the pulley gear 211a with the drive shaft 211 causes the pulley gear 211a and the drive shaft 211 to rotate when the opening and closing rod 110 pushes the greenhouse window 100 all the way up or pulls it, The engagement state between the drive shaft 211 and the pulley gear 211a is released while being disengaged from the slope t on the gear 211a. Accordingly, even if the motor m continues to rotate, the greenhouse glass window 100 can be stopped at the maximum opening or closing state.

When the amount of light to be adjusted during the summer season is adjusted, power is applied to the polymer dispersed liquid crystal layer 20 to make the liquid crystal layer 20 opaque or to change the light transmittance to a lower color, Therefore, it is possible to actively control the amount of light in the greenhouse according to the change in the amount of sunlight, thereby enabling an optimal crop growing environment to be created.

In addition, since the LED element 13 is mounted on the substrate 11 made of glass and used as greenhouse glass, there is no need for a separate design and process for the lighting facility when drying the greenhouse, which is economical. In addition, by melting the snow on the roof of the greenhouse during winter due to the heat generated by the LED device, it is possible to prevent damage to the facility caused by snowfall, and it can help prevent corrosion of the greenhouse frame by preventing condensation.

 Although the present invention has been described with reference to the accompanying drawings, it is to be understood that various changes and modifications may be made without departing from the spirit of the invention. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be determined by the equivalents of the claims, as well as the following claims.
