Abstract:
Various embodiments may relate to an illuminating device. The illuminating device includes a base having a partition board dividing the base into a first accommodating cavity and a second accommodating cavity, a circuit board having light sources and arranged in the first accommodating cavity, and an optical assembly arranged at an opening end of the first accommodating cavity. The partition board, the circuit board and the optical assembly each have at least one air communication structure to enable air from environment to flow into the first accommodating cavity and the second accommodating cavity.
Abstract:
Various embodiments may relate to an optical unit for a light-emitting structure, a light-emitting structure, and a light box comprising the light-emitting structure. The optical unit includes a body and a light-blocking structure, wherein the body includes at least one reflective surface, wherein the light-blocking structure includes a first light-blocking structure and a second light-blocking structure, wherein the first light-blocking structure is formed in one piece with the body, and the second light-blocking structure is arranged in the first light-blocking structure, wherein the first light-blocking structure is arranged to at least partially surround the reflective surface, to block the light leaks from the reflective surface by the second light-blocking structure.
Abstract:
A light-emitting device may include a substrate, a light source arranged on the substrate, and a cover part spaced a certain distance apart from the light source and transmitting light emitted from the light source to outside. The cover part includes a first part, converting wavelengths of a part of light in light emitted from the light source and having different thicknesses at least in two different light-emitting directions of the light source, and a second part, having different thicknesses in the two different light-emitting directions to compensate the thicknesses of the first part.

Abstract:
Various embodiments may relate to a flexible circuit board for an illumination device. The flexible circuit board may include a plurality of device mounting sections, and connection sections connected between adjacent device mounting sections. The plurality of device mounting sections are spaced apart from one another in the longitudinal direction of the entire flexible circuit board.
Abstract:
Various embodiments may relate to a lighting device including a first lighting unit for emitting a first illuminating light, a cover, and a photosensitive coating configured to clean the cover. The lighting device further includes a control device which controls the photosensitive coating to enter an operating state on the basis of whether a situation of ambient environment reaches a first preset condition, and/or which controls the photosensitive coating to enter a non-operating state on the basis of whether the situation of the ambient environment reaches a second preset condition. Furthermore, various embodiments also relate to a cleaning control method of a lighting device.
