Publication number: 20140268635Abstract: A horticultural light for use in green houses and growth chambers of plants, includes multiple LEDs (Light Emitting Diode) configured to excite a single remote phosphor up-conversion unit, typically realized on a replaceable cover glass of the light. The LED emitters are also replaceable, and preferably attached to a trunk, and not a circuit board. The distance between the plurality of LEDs and the remote phosphor up-conversion unit is configured so that the temperature of the remote phosphor up-conversion unit is 40±10 C.°, and the LED is at 130±30 C.° temperature. The combination of being able to control a separation between the remote phosphor up-conversion unit and the LEDs and having multiple LEDs emit to a single remote phosphor up-conversion unit has a great synergistic advantage: this provides a very energy efficient way of designing complex emission spectra that can be used on an industrial scale.Type: ApplicationFiled: January 14, 2014Publication date: September 18, 2014Applicant: Valoya OyInventors: LARS AIKALA, ILKKA KIVIMAKI, JUHA RANTALA
