An LED light source apparatus includes a lamp housing, a lighting module, and a lens. The lamp housing has a first shell body, a second shell body, and a waterproof pad disposed between the first and second shell bodies. The first shell body and the second shell body are covered to each other. The second shell body has an opening. The waterproof pad is provided with a throughhole corresponding to the opening. A light guide flap is disposed on the perimeter of the opening of the second shell body. The lighting module is disposed inside the lamp housing corresponding to the opening. The lens is installed on a side of the lamp housing corresponding to the lighting module. Therefore, the components or the lighting module with a different power can be conveniently replaced by modules and thus the present invention has the flexibility in replacement and maintenance.

A joystick module includes a main body, a light guide structure and a light source. The main body includes at least one hollow region. The light guide structure is disposed within the main body. The light guide structure includes a first light guide part and a second light guide part with different transmittances. The first light guide part has a light output surface exposed outside the hollow region. The second light guide part has a light input surface. The light source is disposed within the main body and located beside the light input surface of the second light guide part. After the light source emits a light beam, the light beam is introduced into the light guide structure through the light input surface of the second light guide part and exited from the at least one light output surface of the first light guide part.

A light guide bar adapted to be interleaved between two connectors which are disposed on a main board. Each of the connectors has a connector lateral wall. At least one connector includes a positioning protrusion. The light guide bar includes a body. The body includes two opposite light guide bar lateral walls and at least one positioning recess. Each positioning recess is formed on one of the light guide bar lateral walls. The at least one positioning recess is adapted to be positioned on the positioning protrusion of the at least one connector. A connector assembly having the light guide bar and the two connectors is further provided.

A support for mounting at least one lighting element on a safety helmet, the support comprising a body having: (i) at least one helmet attaching portion configured for directly or indirectly connecting the support to a portion of the safety helmet, and (ii) a plurality of lighting element attaching portions configured for directly or indirectly connecting the at least one lighting element to the support, wherein the plurality of lighting element attaching portions are configured to facilitate the attachment of the at least one lighting element in a corresponding plurality of positions, such that light projected from the at least one lighting element is focused or directed at a plurality of corresponding angles. An adjustable lighting system and a cable retention arrangement for a safety helmet are also disclosed.

A knob assembly includes a light guide and a control knob that is independently rotatable relative to the light guide. The light guide is positioned at an aperture formed on a surface such that the light guide receives light emitted by a light source positioned below the surface along a vertical direction. The light guide also defines a guide opening, and further includes an opaque and translucent region. The control knob defines a light opening and is rotatably coupled to a stem extending through the guide opening. The control knob is rotatable between a first and second position. In the first position, the light opening is positioned entirely over the opaque region of the light guide along the vertical direction. In the second position, the light opening is positioned entirely over the translucent region of the light guide along the vertical direction. A related cooktop appliance is provided.

An internal component and external interface arrangement for a cylindrical compact computing system is described that includes at least a structural heat sink having triangular shape disposed within a cylindrical volume defined by a cylindrical housing. A computing engine having a generally triangular shape is described having internal components that include a graphics processing unit (GPU) board, a central processing unit (CPU) board, an input/output (I/O) interface board, an interconnect board, and a power supply unit (PSU).

Provided is an illumination apparatus that applies light to an original, the illumination apparatus including: a light source; and a rod-shaped light guide including: an incident surface that receives the light from the light source; a reflection surface provided with a diffusion portion that diffuses the light incident on the incident surface; and an emission surface that emits, to the original, the light diffused by the diffusion portion. An area of the light guide is reduced by an inclination of the light guide from the incident surface side to a middle part in a longitudinal direction of the light guide, and the light guide is provided with the diffusion portion from the incident surface side to the middle part on the reflection surface.

An ornamental device including a decorative plated surface and a backlit assembly is described, and includes a light engine including a light-emitting diode (LED), a light pipe optically coupled to the LED, a light diffuser and a lens assembly. The lens assembly includes a chrome surface finish, wherein the lens assembly encases the light engine, the light pipe and the light diffuser, and is assembled onto a back plate. When the LED is not illuminated, the lens assembly exhibits a chrome appearance, and when the LED is illuminated, light emanates through the lens assembly.

The present invention relates to fluorescence microscopy and specifically to improvements of method for and a corresponding fluorescence microscopy system for allowing separate detection of a plurality of fluorochromes.

The present principles are an illumination system for the front of an electronic device such as a set top box. The device includes a casing having a front wall; apertures on the front wall; a backlight assembly in back of the front wall within the casing; and a light pipe structure to receive light from backlight assembly. The light pipe structure includes plurality of light pipes in which the light pipes have a lower vertical body portion, an upper horizontal body portion, and a central body portion between the lower vertical body portion and the upper horizontal body portion; and a bracket that connects and supports the light pipes in which the bracket is generally planar. The bracket has broad support regions that connect to a back portion of each of the light pipes and a narrow bridging region between broad support regions in which the support regions are broader than the narrow bridging region in the vertical dimension.
