Patent number: 9943040Abstract: A method and apparatus for a horticultural light for use in a horticultural facility that projects a substantially uniform target illuminance onto a flat surface or that projects increasing target illuminance onto a flat surface that increases as the beam angle increases with respect to the optical axis. A lens array of the horticultural light mechanically maintains an optimal separation distance between each LED of the horticultural light and the corresponding lens of the lens array. Each lens of the lens array receives the raw light distribution from the LED and then distributes an optically varied distribution having a nominal centerbeam intensity with an increasing beam intensity as the beam width increases. As the distance to target increases, so does the intensity of the light distribution, which projects a substantially uniform target illuminance, or an increasing target illuminance with increasing angle of incidence, onto a flat surface.Type: GrantFiled: September 25, 2017Date of Patent: April 17, 2018Assignee: Illum Horticulture LLCInventors: Stephen P. Adams, Megan M. Tidd, Johnathan J. Heiner, Darin M. Carpenter

Patent number: 9909727Abstract: A luminaire (12), such as an external light for an automobile or a wall sconce, includes at least first set of optical features (16B, 16F) and a second set of optical features (16A, 16C, 16E, 16G). The first set of optical features (16B, 16F) is configured for use with an LED bulb (10) emitting a first type of light emission pattern (20), such that the luminaire outputs a particular light emission pattern. The second set of optical features (16A, 16C, 16E, 16G) is configured for use with a bulb (10) emitting a second type of light emission pattern (24), such that the luminaire outputs a different type of light emission pattern. In this way, the same luminaire may output different light emission patterns depending on the emission pattern of the bulb. The luminaire's emission pattern may also be dependent on the color emitted by the bulb. Different bulbs may be used or different LEDs may be energized in a single bulb to generate the emission patterns.Type: GrantFiled: September 5, 2014Date of Patent: March 6, 2018Assignee: Koninklijke Philips N.V.Inventor: Paul Scott Martin
