The invention relates to a method for forming a luminaire (1), which has a trough-shaped luminaire housing (10, 110) having a region (25, 125) for accommodating illuminants, which is surrounded by a seal (40), a cover (70, 80) which spans the region (25, 125) and abuts the seal (40) in a peripherally closed manner, a frame-like holding element (50, 150), which presses the cover (70, 80) into abutment with the seal (40). For the luminaire housing (10 110), the cover (70, 80) and the holding element (50, 150), are each available in at least two different variants, which can be combined in any way, wherein in order to form the luminaire (1) according to desired output properties and/or properties with regard to heat dissipation or moisture resistance, a suitable luminaire housing (10, 110), a cover (70, 80) and a holding element (50, 150) are in each case selected and the selected components are assembled to form the luminaire (1).

A light fixture, including: a printed circuit board (PCB) extending in a first direction, the PCB includes bends along one or more sides extending in the first direction for rigidity; the PCB configured to transfer thermal heat directly to ambient air; and one or more groups of light emitting diodes (LEDs) operatively coupled to a component-side of the PCB and between the bends.

Disclosed is a shelf light for plant growth having vertical stand with a plurality of wooden partitions vertically arranged in parallel at intervals and wooden vertical rod connected between adjacent wooden partitions, and lighting unit on top of vertical stand. Wooden partition on topmost end vertically is constructed as light holder for arranging lighting unit; power box powering lighting unit is mounted on another wooden partition below light holder; power box is provided with plug connecting wire accessing to electricity, with side wall configured with USB-A, USB-B and USB-C interfaces and top surface configured with wireless charging pad. The utility model, a framework entirely formed by connecting all-wooden materials, has firm structure, with functions of plant growth light, USB power docking station and wireless charging pad, so as to provide green decoration for home environment while compounding use of charging base stations, resulting in strong functionality and high space utilization.

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.
