A lighting system configured for daylight emulation. The system includes a plurality of light sources for generating a daylight-emulating output light spectrum and a ventilation element for generating a simulated breeze to artificially emulate conditions in an outside environment of an enclosed structure in which the lighting system is disposed. The system also includes a controller for dynamically controlling at least one of the intensity, directionality and color temperature to emulate sun position for at least one of a geography and time of day. The controller also controls the generated simulated breeze of the ventilation element to be one of a cool breeze and a warm breeze to artificially emulate the outside environment in correspondence with the artificially emulated daylight spectrum. The system further includes a networking facility that facilitates data communication with at least one external resource.

This new utility invention discloses a waterproof LED lamp comprising a power supply box and an LED lighting module block detachably connected to the power supply box. A power driving board and an LED controller are disposed in the power supply box. The LED lighting module block includes at least one LED module, which includes a module heat dissipater. The power supply box and the LED module are arrayed side-by-side in a parallel manner, and a lateral surface of the power supply box matches a lateral surface of the LED module in size and shape so that the power supply box and the LED module may be in close contact. The power supply box and the LED lighting module block are electrically connected with a conducting wire, which is arranged to go through the wiring hole and the slot. The power driving board provides power to the LED controller and the light board, and the LED controller drives the LED lighting beads on the light board to illuminate. The present invention disposes the power supply and power driver inside a power supply box to separate the power supply from the LED light source. For product maintenance, the power supply or LED light source may be replaced individually.

Solid state light fixtures include a plurality of blue-shifted-yellow/green light emitting diode (“LED”) packages and a plurality of blue-shifted-red LED packages, where the solid state light fixture emits light having a correlated color temperature of between 1800 K and 5500 K, a CRI value of between 80 and 99, a CRI R9 value of between 15 and 75, and a Qg value of between 90 and 110 when the blue-shifted-yellow/green LED packages and the blue-shifted-red LED packages are operating at steady-state operating temperatures of at least 80° C.

A light system includes a first substrate and a second substrate having the first substrate thereon. A light emitting diode (LED) is connected to the first substrate. An encapsulation layer covers the LED and at least a majority of the first substrate.

An illumination apparatus, including: a light source assembly, a circuit board, a fin assembly, and a fan. The fin assembly includes a plurality of fins arranged at intervals.
