Plant cultivating method, cultivating device, and its lighting device
View Patent ↗A plant cultivating device (A), comprising aluminum long square pipe trays ( 5 ) for storing plants ( 35 ) together with culture solution, a conveyor device ( 2 ) for feeding the trays ( 5 ) in order in lateral direction, and a lighting device ( 3 ), having a number of light-emitting diodes disposed thereon, located over the conveyor device ( 5 ), the lighting device ( 3 ) being disposed so as to be higher gradually from the upstream side to the downstream side of the conveyor device ( 2 ), wherein a funnel-shaped holder ( 30 ) holding the upper part of the plant ( 35 ) is provided on the upper surface of the tray (5), and a planting conveyor ( 6 ) and a harvesting conveyor ( 7 ) for supply and retrieval, a reflecting wall ( 8 ) provided between these conveyors and the conveyor device ( 2 ), and transfer bars ( 41 ) for transferring the trays ( 5 ) between the conveyor device ( 2 ) and the planting and harvesting conveyors ( 6,7 ) are installed on the upstream and downstream sides of the conveyor device ( 2 ).
1. A lighting-emitting panel, comprising;
base plate;
circuit board mounted on the base plate;
light-emitting unit provided with a number of lamps aligned and fixed on the circuit pattern of the circuit board;
translucent cover placed with a space adjacent to the base plate;
sealing material sandwiched between the base plate and the cover to keep the space airtight;
the lamps being fixed on the circuit board using a conductive adhesive; and
a frame sandwiched between the base plate and the cover,
wherein a sealing material is packed around the frame, the space is filled with inactive dry gas, and a desiccant and/or deoxidizer is accommodated inside of the frame.
2. A lighting-emitting panel according to claim 1 , further comprising;
lamp provided with a concave reflecting plate;
light-emitting element mounted on the reflecting plate;
bonding wire to connect the light-emitting element and an electrode; and
translucent molding material of synthetic resin to enclose the light-emitting element and the reflecting plate.
3. A light emitting panel according to claim 1 , wherein the conductive adhesive is composed of soldering cream.
4. A light-emitting panel according to claim 1 , wherein the base plate serves as a circuit board.
5. A light-emitting panel according to claim 1 , further comprising:
a piping for cooling the light-emitting unit provided at a rear side.
