Abstract

Disclosed are devices, methods, and techniques for providing photosynthetically active radiation (PAR) for plants, i.e. lighting. Devices including light emitting diodes (LEDs) are disclosed than can be used as lighting for plants grown indoors or outdoors. The disclosed LEDs significantly reduce power consumption for horticulture lighting, provide the wavelengths needed by plants to optimize growth, and provide growers with the ability to control PAR in order to optimize grow strategies. The disclosed LEDs provide the correct wavelengths of light (300-800 nanometers (nm)) for photosynthesis with a uniform intensity across the LED device thereby providing an even photon delivery to plant canopy and into the underlying leaves within the plant canopy. The intensity and mixture of wavelengths provided by the LED device can be controlled by adjusting the electrical power delivered to individual LEDs included in the LED device.
