A light emitting arrangement (100, 200, 300) is provided, comprising: a body (10) of solid material having a surface (11); a light guiding member (101, 110) partially embedded into said body, having a plurality of discrete light outcoupling regions (103) comprising light outcoupling means (230, 730, 830, 930) distributed along a longitudinal direction of the light guiding member, and a plurality of discrete, non-outcoupling regions (102) distributed along a longitudinal direction of the light guiding member, wherein said plurality of light non-outcoupling regions of the light guiding member are embedded by said body and said plurality of light outcoupling regions of the light guiding member are exposed on the surface of said body, wherein said non-outcoupling regions (102) form light incoupling regions comprising light incoupling means (220, 320, 420, 520, 620); and a plurality of solid state light sources (12) embedded within said body (10) of solid material arranged to emit light towards said light incoupling regions. The light emitting arrangement provides a body with an illuminated surface, and the plurality of light outcoupling regions enables efficient lighting, with no or little loss of light.

A lighting device includes: a case made from a material allowing light to penetrate therethrough and having a cylinder shape with a closed bottom; a substrate including a light emitter configured to emit light; and a cover made from a rigid material, press-fitted and installed in the substrate so as to cover the light emitter, and installed inside the case together with the substrate.

An illumination module and a lamp, the illumination module is adapted to be assembled with at least two different installation components. The illumination module includes: a housing including a main body part, a side wall extending from the main body part, and an installation region for disposing the installation components, the installation region includes a first installation part and a second installation part, the first installation part is located on an outer periphery of a back face of the main body part of the housing and configured to be assembled with an installation component, and the second installation part is located on the side wall at the back face of the housing and configured to assemble with an installation component; and a light source component, installed on a front face of the main body part of the housing.

A soft collision target, in particular for use within the framework of non-destructive collision tests, has an illumination device that comprises at least one illuminant and a covering structure, wherein the covering structure surrounds the illuminant and is configured to absorb forces acting on the illumination device on a collision and/or to conduct them at least partly past the illuminant.

The ceiling lamp includes a top plate, a ceiling shell, an air guide shell, a main shell and a lampshade. A first accommodation cavity is formed between the ceiling shell and the air guide shell. A second accommodation cavity is formed with the lampshade. An illuminant board is configured in the second accommodation cavity. A fan is configured coaxially on the axis of the air guide shell. An air passage connected with the fan is opened on the lampshade by invagination along the axial direction of the lampshade. At least one air hole is formed on air guide shell. A filter screen module is detachably configured in the air passage. The external air flow is discharged from the air hole through the fan by the filter module, or enters from the air hole and then discharges through the filter module after passing through the fan.

An LED luminaire cover light diffuser and a use thereof are provided. The LED luminaire cover light diffuser is used for an illumination cover of an LED luminaire that illuminates a target object to enable the target object to be seen. The LED luminaire cover light diffuser includes base resin; light diffusing agent; and a coloring matter that at least partially absorbs light in a wavelength range from 500 to 600 nm. The LED luminaire cover light diffuser achieves a relative value of spectral radiance at a wavelength of 450 nm within a range from 1.60 to 15 with the spectral radiance at the wavelength of 550 nm defined as 1, when the spectral radiance is measured with a specific white LED used as a measurement light source and with the LED luminaire cover light diffuser provided to cover the white LED.

A submersible light has an elongated tubular inner housing extending along an axis, an LED strip carrying a plurality of light-emitting diodes fitted into and extending axially inside the inner housing, and an elongated tubular outer housing longer than the inner housing and into which the tubular inner housing fits coaxially leaving end spaces in the outer housing at axially opposite outer ends of the inner and outer housings. Respective bodies of cured potting compound sealing the end spaces at the outer ends of the inner housing.

A method of illuminating a target area and driving rotation a driven tool comprises coupling a light attachment assembly to an elongated extension member by placing a portion of the elongated extension member within a hollow portion of a sheath of the light attachment assembly. Activating a light source of the light attachment assembly. Positioning the driven tool within the target area while grasping the light attachment assembly. Driving rotation of both the driven tool and the elongated extension member while grasping the light attachment assembly when the driven tool is positioned within the target are such that the portion of the elongated extension member housed within the hollow portion of the sheath rotates relative to the light assembly.
