The present invention relates to a decorative lighting panel for mounting to a home exterior via mounting holes, brackets, bolts, etc. The panel has a frame that includes a groove between a front surface and rear surface of the panel. A plurality of illumination sources in the form of LED strips or chips are disposed in the groove, for providing illumination and a retractable plastic cover is designed to reveal the LEDs when pulled down. The plastic cover generally covers the LEDs when illumination is not required. The panel has wireless capabilities allowing a remote control or a handheld electronic device with an installed software application to remotely control the operations of the panel. The panel is designed to be electrically connected to other similar panels to form a series of panels for creating a long segment of illumination.

Disclosed embodiments provide a lighting controller and illumination system. A controller may include a phase-cut dimmer, a lighting receiver module, and at least two banks of lights. In embodiments, the lights may be LED (light emitting diode) lights, and the lighting receiver module is an LED driver. A first bank of lights illuminates at a first CCT and a second bank of lights illuminates at a second CCT. The controller communicates encoded information on a carrier signal that is received by the lighting receiver module. The lighting receiver module decodes the received encoded information and adjusts the intensity of the first and second bank of lights to create a combined CCT. The combined CCT may be realized by a combination of light from the first bank of lights and light from the second bank of lights. The combined CCT may be representative of a specified CCT.

A light engine that produces UVA1 light, but not UVA2 or UVB radiation, that will provide a human or animal subject a beneficial application of artificial UVA1 light without the deleterious effect of the UVA2 and UVB light. Methods of providing UVA1 light to the human or animal subject over various periods of time provide positive treatments that can reduce stress, reduce anxiety, increase a pain threshold, and induce interferon production. Exposure to UVA1 wavelength light (360-400 nm) provides a positive effect on both humans and animals. This is especially true when the humans or animals do not receive UVB and UVA2 at the time that the UVA1 light is received, and the ratio of UVA1 light to (UVA1 light+visible light) is greater than 10%.

An information processing device includes a picture image inputter configured to acquire a picture image imaged by a camera and at least one processor configured to execute a program stored in a memory. The at least one processor detects, from the picture image acquired by the picture image inputter, light emitted by a light-emission device, acquires, based on brightness of the detected light emitted by the light-emission device, set brightness information indicating an appropriate brightness for light to be emitted by the light-emission device, and transmits the acquired set brightness information to the light-emission device.

Lighting apparatuses include an enclosure around first and second light engines. The enclosure has a diffuser over first, second and third regions. The first and second regions are separated by the third region; a first light spectrum is emitted from the first region; a second light spectrum is emitted from the second region; and a mixture of the spectrums is emitted from the third region. In some embodiments, the first spectrum has a CCT≥7000K; the second spectrum has a CCT≤6500K. In some embodiments, the first spectrum has a first CCT≥3500K; the second spectrum has a second CCT≤6500K; the second CCT<first CCT and the difference between the CCTs is at least 1000K. In some embodiments, the first spectrum has a color bounded by a first set of chromaticity coordinates, and the second spectrum has a color bounded by a second set.
