A lighting module includes a heat sink with a sidewall and a partition defining two cavities, a LED light source disposed in one cavity to emit light, a driver module disposed in the other cavity with driver circuitry to provide electrical power to the light source, and an optical assembly to provide a desired emission profile. The optical assembly is field-changeable and includes a cover lens with snap-fit connectors to facilitate removal and replacement. The optical assembly further includes either a reflector coupled to the cover lens or an optical lens coupled to the heat sink via an optic holder. In some examples, the driver circuitry facilitates dimming of the light source. The heat sink also dissipates heat generated by the light source and the driver circuitry to maintain desired operating temperatures and thereby facilitate increased light output.

A lighting apparatus includes a light passing cover, a light strip, a heat dissipation plate, a manual switch, a driver and a bottom cover. The light passing cover defines first elongated cavity. The light strip is mounted with multiple LED modules. The heat dissipation plate is used for mounting the light strip on a first side of the heat dissipation plate. The manual switch is disposed for selecting a switch setting. The manual switch is placed on the first side of the heat dissipation plate. The driver converts an external power source to a driving current supplied to the multiple LED modules. The driver is electrically connected to the manual switch for controlling the driving current supplied to the multiple LED modules to adjust an output light of the multiple LED modules according to the selected switch setting. The bottom cover defines a second elongated cavity.

A high-durability tri-proof lamp with color temperature adjustment function is provided, which includes a lamp housing, a movable support plate, a circuit board and a driving power source. The lamp housing has two connection holes and a guiding groove. The lamp housing is hollow and has a chamber; the connection holes are disposed at the two ends of the lamp housing. The guiding groove includes two lateral guiding slots disposed at the two sides of the chamber. The movable support plate is disposed in the chamber. One side of the movable support plate and the other side thereof are inserted into the lateral guiding slots, such that the movable support plate is able to move along the guiding groove. The circuit board is disposed in the chamber and connected to the movable support plate. The driving power source is disposed on and electrically connected to the circuit board.

A terrestrial vehicle lighting module which includes an electroluminescent source including at least one electroluminescent element, an electronic device designed to control the electroluminescent element, and an interposer electrically connecting the electroluminescent source and the electronic device.

A base unit (1), e.g. a luminaire, comprises fixation means (3, 5, 15) configured to fixate a module (11), e.g. a light module, in the base unit. The fixation means, e.g. comprising one or more protrusions (15), one or more recesses (3) and one or more magnetic field generators (5), is configured to release the module from the base unit upon detecting an unmanned aircraft (31) being docked with the base unit or the module.

Aspects of the present invention generally relate to an apparatus that combines a light source, a speaker, and other electrical components in a single unit to produce lighting and sound effects. The apparatus may be sized and configured for use in a number of applications. Further, the apparatus may have a number of operating states that may include light and sound effects that correspond with one another.

A backlight source module and a display device are provided. The backlight source module includes a back plate structure and a rubber member. The back plate structure includes a bottom plate, and a first side plate and a second side plate respectively connected with the bottom plate, and the first side plate and the second side plate oppose each other. A light-emitting portion, a light-guiding component and the rubber member are sequentially disposed on the bottom plate along a first direction pointing from the first side plate to the second side plate. The rubber member is only disposed at the second side plate.

An illumination device for a vehicle is provided, and includes an optical device such as a reflector, with a dome and with a positioning pin. A light emitting assembly is also included with a printed circuit board and a semiconductor light source such as a light emitting diode. The light emitting assembly comprises a bracket with at least one spring for exerting a pretension force on the dome of the optical device. The printed circuit board comprises a positioning hole for receiving the positioning pin and to position the light emitting assembly relative to the optical device.

A light-emitting diode (LED) tube lamp comprising a tube, end caps with contact pins and located on both ends of the tube, a first rectifying circuit and a second rectifying circuit and a filtering circuit that are coupled with the contact pins on the two end caps respectively, and a switch circuitry that is located between the rectifying circuits and the filtering circuit characterized in that the switch circuitry is capable of detecting whether the LED tube lamp is correctly installed on a lamp socket so as to reduce the risk of electric shock.

A lighting fixture is disclosed with effective disinfection properties against bacteria, fungi, and viruses. The fixture includes a fan to continuously draw air into the light fixture. The air drawn in is irradiated with UV radiation within the fixture, such as is provided from UV LED chips. The relatively small volume of the light fixture allows the flux or energy density of the UV radiation to be made more intense. After the air is sterilized, it can be put back into the room or building in which the fixture is placed. The white light provided by white light LEDs in the fixture provides illumination, and can further provide significant emission peaks at 405 nm and 470 nm which is also useful to pathogen inactivation.
