The control device may include one or more elements that are configured to limit infiltration of liquids into the control device and thus may be consider to be water-resistant or water-proof.

A light guide receptacle for mounting a plurality of light guides in the interior of a housing part, with a plurality of light bulkheads, is configured to arrange the plurality of light guides, which are mechanically coupled to one another by means of a web, in each case in intermediate spaces between two light bulkheads of the plurality of light bulkheads and to optically decouple spatially adjacent light guides from one another by means of the respective light bulkhead, wherein the plurality of light bulkheads are integrated components of the housing part.

The invention discloses a solar lamp, including a base, a light source, a power unit, a lampshade, and a solar panel, wherein the lampshade is buckled on the base to form an accommodating space; the light source, the power unit, and the solar panel are all disposed in the accommodating space; the power unit is electrically connected to the solar panel and the light source; and the lampshade is made of a light-permeable material, wherein a plurality of light guide elements for guiding light are disposed on an outer side the lampshade.

An optical device including a first substrate, a light source, a second substrate, an image capturing device, a lens module and a lens holder is provided. The light source outputs a first light beam. The second substrate includes a first surface and a second surface opposite to the first surface and closer to the first substrate. A scattered light beam which is generated by the first light beam entering an object touching the first surface of the second substrate and scattered in the object is a second light beam. The image capturing device receives a third light beam. The third light beam is the second light beam normally incident to the second surface and transmitted to the image capturing device. The lens module focuses the third light beam to be captured by the image capturing device. The lens holder is located between the light source and the image capturing device.

To provide an optical circuit in which the deviation of optical power per wavelength is reduced. An optical multiplexing circuit of the present disclosure includes a transmission light adjustment circuit, which is a loss portion that provides excessive loss in paths of red light and green light so as to have the same power as the output power of blue light. By varying the path length of each color, a path for wavelength with great propagation loss is short and a path for wavelength with a slight loss is long.

A light guide is disclosed. The light guide may comprise a wedge shape. The light guide includes a light receiving surface, a light transmission region, a transition region, and a light emission region. Light emission region includes a first major surface and an opposing second major surface. The light emission region may include a plurality of steps disposed along a length of one or both of the major surfaces. The light emission region may also include a plurality of vertically-extending flutes along one or both of the major surfaces. A luminaire assembly incorporating the light guide is also disclosed.

An electrical connector comprises: an electrical connector housing; a light-guiding component disposed on a sidewall of the electrical connector housing; a secure-connecting structure disposed between the sidewall of the electrical connector housing and the light-guiding component to secure the light-guiding component to the sidewall of the electrical connector housing. The secure-connecting structure comprises a first securing component and a second securing component. The first securing component comprises at least one securing hole comprising an insertion hole and a retaining hole. The insertion hole communicates with the retaining hole. The second securing component comprises a securing protrusions comprising a first securing part and a second securing part disposed on the first securing parts. While disposing the second securing component into the first securing component, the second securing part passes through the insertion hole and then the first securing part moves into the retaining hole from the insertion hole.

A sensitivity-adjustable mouse includes a casing, a switching button, an illumination module and a lightshade cover. The switching button is installed on the casing and swingable relative to the casing. The illumination module is disposed within the casing and located under the switching button. The illumination module emits plural light beams to the switching button. The lightshade cover is connected with the switching button and arranged between the switching button and the illumination module. The plural light beams are divided by the lightshade cover. The illumination module and the lightshade cover are covered by the switching button. Due to the appearance of a single button structure, the appearance of the mouse is aesthetically pleasing.

Disclosed herein are lighting apparatuses that have an oblong optic that corresponds to a plurality of light sources. According to certain embodiments, a lighting apparatus includes a plurality of light sources that are arranged along a linear direction, and an optic that is configured to receive light from each light source of the plurality of light sources. The optic has an oblong shape with a long axis that is parallel to the linear direction, and the optic is configured to emit an output light beam that is substantially rotationally symmetric in a plane that is orthogonal to an emission direction of the plurality of light sources.
