The invention relates to a suspended luminaire for providing sound dampening. The luminaire (100) has a first acoustic panel (105) and a second acoustic panel (120). The first acoustic panel (105) has a first curved shape, and the second acoustic panel (120) has a second curved shape, wherein the first curved shape is a mirror image of the second curved shape. The first top side (111) of the first acoustic panel (105) and the second top side (126) of the second acoustic panel (120) are separated by a top gap (150). The first bottom side (113) of the first acoustic panel (105) and the second bottom side (128) of the second acoustic panel (120) are separated by a bottom gap (156). The luminaire (100) further has a light module (160) that is attached proximal to the first bottom side (113) of he first acoustic panel (105) and proximal to the second bottom side (128) of the second acoustic panel (120).

A smart home-care lighting system includes a lighting device having a portion that is light transmittable. The lighting device receives therein an illumination module for purpose of illumination, a detection module for detecting an outside environment, an alarm module and a sound effect module operable in combination with the detection module for indication and alarming, and an image pickup module for capturing and recording images. The lighting device also includes, arranged therein, a microprocessor and a main control module for transmitting and storing personal habits and health information. The device is arranged such that image can be captured in ranges that does not overlap to provide a surveillance range of 360-degree full view and operation can be made with the main control module for determination for proper action to be taken and may be used in combination with household appliances to construct a smart home-care system that benefit home members.

A lighting system is disclosed that includes elongated LED light fixture with one or more master circuit boards configured to power light emitting diodes. The elongated LED light fixtures include modular light boards with arrays of light emitting diodes that interchangeably couple to the matched connectors on the master circuit board. The system further includes elongated LED light fixtures with telescoping end features, fenestrated diffuser optics at ends of the elongated LED fight fixtures and/or pivoting corner features that join sections of the elongated LED light fixtures.

A lamp assembly, a lamp system, a method for assembling lamp system, and a method for disassembling lamp system are provided. The lamp assembly includes a lamp and a connector assembly. The lamp includes a frame body, a light source assembly, and an electrical connector assembly. The frame body has an accommodating space. The light source assembly is fixed on the frame body. The electrical connector assembly is disposed in the accommodating space and is connected to the light source assembly. The electrical connector assembly includes a first connector and a second connector, and the first connector and the second connector are connected to each other by a power wire and a signal wire. The connector assembly includes an electrical connecting member. The connector assembly is configured to be connected to the aforementioned lamp and another lamp through the electrical connecting member.

A fixing mechanism comprises a casing, a plurality of clamping members, and a biasing member respectively configured in the casing. The casing includes an inner surface and surrounds an accommodating space, and the accommodating space has a large-diameter end and a small-diameter end. The plurality of clamping members are configured in the accommodating space, and each clamping member has an outer surface facing the inner surface. A cross section of the outer surface along the axial direction is arc-shaped and the outer surface of the clamping member contacts with the inner surface of the casing partially. The clamping members can be pushed toward the large-diameter end of the accommodating space to separate the clamping members from each other, so that the wire can move between the clamping members. The biasing member is disposed in the accommodating space and located on one side of the large-diameter end. The biasing member can push the clamping members toward the small-diameter end of the accommodating space to make the clamping members close to each other to clamp the wire. Therefore, the contact area and friction force between the clamping members and the inner surface of the casing can be reduced, and the convenience of the operation can be improved. The invention also provides a lamp using the fixing mechanism.

Disclosed embodiments relate to a combination axial fan and LED lighting system configured to fit into the footprint of a standard ceiling tile. Disclosed embodiments further include ceiling tiles with a built-in fan and/or LED lighting. The disclosed systems may include a housing container and an axial fan. The fan has a fan cavity including air diversion mechanism to direct air from the fan cavity toward the lighting and fan components. The inventions include an airflow surface to direct air existing the fan cavity along an LED light fixture. Moreover, disclosed embodiments include one or more UV light sources which irradiate contaminants as air flows through the ceiling tile.
