20110209400 | LED LIGHTING DEVICE FOR GROWING PLANTS - Disclosed is a lighting assembly for growing plants. The lighting assembly has a first light source emitting light in a first wavelength range of 600 to 750 nm; a second light source emitting light in a second wavelength range of 375 to 500 nm; and a controller for controlling the output of the first light source independent from the output of the second light source. Disclosed are also an enclosure for growing plants, and a method for growing plants. | 09-01-2011 |
20110148313 | METHOD AND CIRCUIT FOR CONTROLLING AN LED LOAD - The invention relates to a method for controlling an LED load. First an input voltage is supplied to an inductive element. Subsequently, a current is drawn through the inductive element for a first predetermined time period. Finally, a current is supplied from the inductive element to a first terminal of the LED load during a second time period. The first predetermined time is controlled to maintain a predetermined average current through the LED load. | 06-23-2011 |
