The present disclosure relates to a lighting device for automatically switching between a visible light source and an infrared light source. The lighting device may include a light source, an infrared filter, and a driving module for driving the infrared filter.

A lighting system includes control adapters and a lighting controller that sends commands and data over an AC power line to power and control the lamps associated with the control adapters. Lighting themes are uniquely programmable color and intensity that are applied to a collection of control adapters to achieve different lighting modes instantly, without the delay that programming each control adapter individually incurs. The plurality of control adapters receive theme lighting information over the power line and store the theme information in memory. The lighting controller sends a single command to the collections of the control adapter groups to apply the theme or a multiple of themes to run in sequence as a pattern. Each control adapter retrieves and applies the theme information associated with the pattern.

A lighting system includes lighting fixtures and a lighting controller that sends commands and data over an AC power line to power and control the lighting fixtures. Lighting themes are uniquely programmable color and intensity that are applied to a collection of lighting groups to achieve different lighting modes instantly, without the delay that programming each lighting fixture individually incurs. The groups of lighting modules receive theme lighting information over the power line and store the theme information in memory. The lighting controller sends a single command to the collections of the lighting groups to apply the theme. Each lighting module retrieves and applies the theme information.

Provided is a lighting device with an inactivation function, the lighting device allowing the addition of an inactivation function while being equal to conventional lighting devices in device size. The lighting device with the inactivation function includes: a UVC light source to emit ultraviolet light having a peak wavelength in a wavelength range from 200 nm to 230 nm; an LED light source to emit visible light; a single unit of an AC/DC converter to convert an AC voltage derived from an external power source into a DC voltage and output the DC voltage; a UVC light source-specific circuit part to convert the DC voltage output from the AC/DC converter into a voltage for lighting the UVC light source; and an LED light source-specific circuit part to convert the DC voltage output from the AC/DC converter into a current for lighting the LED light source.

A show effect system may include a plasma tube configured to generate an electric arc within the plasma tube and a light strip extending along the plasma tube. The light strip may include a plurality of light emitters configured to output light through the plasma tube and backlight the electric arc generated by the plasma tube.

An auxiliary power system for powering an auxiliary circuit is connected to the same power source that powers the lighting element within a luminaire. The auxiliary power system may be connected to the output of the power source in series or in parallel with the lighting element. The power source may be an LED driver and the lighting element may include one or more LEDs or the power source may be an electronic ballast and the lighting element may be one or more fluorescent lamps.
