A luminaire delivers indirect light through a light exit window, after reflection by a reflector housing. The reflector housing comprises a central area and a peripheral area. The peripheral area is for redirecting light to the light exit window, whereas the central area is outside the area of the light paths to the light exit window. A component is located at the central area.

A starry sky aurora atmosphere lamp with an integrated lampshade is provided, including a base, a main light source, a multi-layer housing, and a connector. The main light source is arranged at a center of the base and can project light upwards to form a starry sky atmosphere light. The multi-layer housing can cover the base, such that the main light source is located within an accommodating space formed between the base and the multi-layer housing. The multi-layer housing includes an inner light-gathering cover and a semi-obscuring outer cover covering a surface of the light-condensing inner cove. The connector connects the base with the multi-layer housing. When the multi-layer housing is rotated to cover the base, the multi-layer housing and the base have integral and continuous appearance, and the starry sky atmosphere light is automatically changed to colored glaze light of a small night lamp.

The present disclosure provides a light-emitting substrate, a light-emitting apparatus and a lighting apparatus. The light-emitting substrate includes: a base substrate including a plurality of light-emitting regions and a plurality of non-light-emitting regions, where the plurality of light-emitting regions are arranged in an array; a plurality of light-emitting units located in the plurality of light-emitting regions, respectively, where in each light-emitting region, more than one light-emitting unit is arranged in an array; a covering layer covering the light-emitting region and the non-light-emitting region; and a plurality of support structures arranged in an array and evenly distributed in the plurality of non-light-emitting regions and/or between the plurality of light-emitting units, where the support structures are used to support the covering layer.

A printed circuit board (1) for an LED module (2) comprises mechanical weaknesses (11) in a substrate of the printed circuit board (1), which weaknesses form at least one at least electrically interruptible substrate bridge (12A, 12B), and a plug connector (13) having four terminals (13.1-13.4) A first LED light source (14) can be connected between a first anode-cathode pair (13.1, 13.4) of the four terminals (13.1-13.4), and a second LED light source (15) can be connected between a second anode-cathode pair (13.2, 13.3) of the four terminals (13.1-13.4) A pair of anodes (13.1,13.2) of the four terminals (13.1-13.4) is galvanically interconnected via a first (12A) of the at least one substrate bridges (12A, 12B) The printed circuit board (1) can be connected using the plug connector (13) to at least one LED driver for the LED module (2) via two or three separate galvanic connections depending on the state of the at least one substrate bridge (12A, 12B).

An easy-to-assembly combined fan, includes a frame and a light strip. The light strip is arranged inside an annular limit groove inside the frame. Light bulbs, a first electrode, and a second electrode are integrated at a circuit board of the light strip. The circuit board constitutes a light board of the fan, and the first electrode and the second electrode constitute two interfaces of the fan. The integration arrangement of the light board and the interface facilitates fan assembly.

A paint roller pole light device is disclosed that comprises a repositionable light component that is removably attached via straps to a paint roller pole. Specifically, the repositionable light component is attached to a repositionable arm via an omni-directional mount. In this manner, the device illuminates the area directly in front of the paint roller during use. Further, the device is available in a kit comprising two repositionable lights, one for use and one to be charged, with straps to hold the light, and a charger.

An LED lighting device includes a seat, an optical assembly and a light source. The seat has a baseplate and a sidewall. A chamber is formed between the baseplate and the sidewall. The optical assembly completely covers a light-emitting side of the LED lighting device. The light source is disposed in the chamber of the seat and includes multiple LED arrays. Each LED array includes an LED chip. The optical assembly includes an optical unit. The optical unit includes multiple first optical members and multiple second optical members corresponding to the first optical members. The LED arrays correspond to the first optical members. Each first optical member possesses an effect of light diffusion resulting from its own material property. Each second optical member includes one or more sets of optical walls. Each set of optical walls surrounds one of the first optical members.

A projection device with dynamic light effect is provided, which includes at least one LED light source, a condensing lens, at least one external projection mono-convex lens, and further includes at least one filter. The filter is located between the condensing lens and the external projection mono-convex lens, an out-light surface of the condensing lens is provided with a first ripple. An upper and/or a lower surface of the filter are provided with a second ripple; being refracted by an interference pattern on the first ripple through the condensing lens, emitted light corresponding to the interference pattern on the first ripple is formed. Then, the light passes through the filter and undergoes two refractions. The light is refracted by the interference pattern on the second ripple, resulting in a refraction effect of the interference pattern superimposed on the first ripple and second ripple.

A lamp body, a table lamp, and a stake lamp are provided. The lamp body includes a lampshade, a light-emitting body, a terminal connecting base, a terminal connector, and a wire. The lampshade defines an opening. The light-emitting body is placed in the lampshade through the opening. A plug is disposed on one end of the light-emitting body.
