The control system for a stage light fixture with photobiological safety includes a control unit connected to a motor assembly and a light source and configured to control the stage light fixture to operate, and a distance sensor connected to the control unit, and configured to acquire an instant distance from a living being to the stage light fixture. The control unit stores a light radiation hazard exposure radiance limit value and a light fixture irradiance value acquired in advance per unit of time and distance, and acquires a parameter of the living being entering an irradiation danger zone according to the instant distance, the light radiation hazard exposure radiance limit value, and the light fixture irradiance value. When a hazard condition reaches the parameter of the living being entering the irradiation danger zone, the control unit controls the stage light fixture to move to eliminate the hazard condition.

The present invention discloses a lamp structure. An accommodating cavity is provided for disposing a lamp board. An insulating unit seals the opening of the accommodating cavity for preventing accidental electric shocks when a user cleans or maintains the lamp structure. Placing the lamp board inside the accommodating cavity, the space occupied by the lamp board on the base may be saved. The insulating unit may prevent foreign matters or water from contacting the lamp board and resulting in short circuit or failure in the lamp board. One or more heat dissipating unit may be disposed in the accommodating cavity and used as the heat dissipating structure for the lamp board. A recess may be disposed on an inner side of the accommodating cavity. The recess communicates with the accommodating cavity. A capacitor may be disposed in the recess and connected electrically to the lamp board.

The disclosure provides a lighting device that provides light via one or more non-incandescent lamps that can be moved and arranged while operating. The lighting device includes a non-opaque shroud, or casing, that sits upon a base to create a volume within which the non-incandescent lamps rest and can be moved while still providing light. The non-incandescent lamp can use one or more light-emitting diodes (LEDs). The non-incandescent lamps can provide illumination with minimal heat and low power consumption that contributes to user interaction and can be battery powered. In addition to a non-incandescent lamp, a lighting device having at least one of the non-incandescent lamps is disclosed. Additionally, a lighting system having at least one of the lighting devices and a lighting control application is provided herein.

A laser-based light source includes a laser device configured to generate laser light of a predetermined laser wavelength and emit this laser light as a laser beam. A light-conversion device is configured to convert at least part of the laser light into converted light and a laser-output sensor is configured to determine a laser-output signal proportional to the output of laser light emitted by the laser device. Further, a converted-light sensor is configured to determine a converted-light signal proportional to the output of converted light emitted by the light-conversion device. A controller is configured to receive the laser-output signal and the converted-light signal, to determine a safe-to-operate parameter, based on the laser-output signal and the converted-light signal, and to control the operation of the laser-based light source based on a comparison of the safe-to-operate parameter with a at least one predefined threshold.

A circuit board configuration adapted to carry electronic components of a power supply module is provided. The circuit board configuration comprises: a first circuit board, having a first plane configured to dispose and connect a part of the electronic components; and a second circuit board, electrically connected to the first circuit board and having a second plane configured to dispose and connect another part of the electronic components, wherein at least one of the first and the second circuit boards is disposed, perpendicular to an axial direction of the lamp tube, in an interior space formed by the lamp tube and at least one of the two end caps, so that the a direction normal to the first and the second planes is substantially parallel to the axial direction of the lamp tube.

A linear luminaire includes a linear channel defining an interior space and a linear light inset configured for being inserted into the channel in the interior space. The light inset includes a cover and a printed circuit board fixed to the cover. The printed circuit board supports a plurality of light emitting diodes. The cover base wall includes a translucent portion. The light emitting diodes are arranged for emitting light through the translucent portion. The cover includes two cover connectors, each configured for being snapped into the channel to hold the cover in the interior space. The cover connectors are on an opposite side of the printed circuit board as the translucent portion.
