A lid to be connected to a housing of a status display for a sensor, with a basic body comprising a covering surface and at least one side wall, wherein the basic body has at least one light-transmissive light emitting region to facilitate an illumination of desired areas of the lid that is homogeneous and space-saving, with a first reflector unit and a second reflector unit arranged opposite each other, and wherein an opening for arranging a lighting means is formed in the second reflector unit, wherein the light emitted by the lighting means is reflected to the at least one light emitting region by means of the first reflector unit and the second reflector unit.

An indicator light (1) includes a light source, a lens (4), and a cylindrical globe (5). The light source includes a center LED (2A) disposed on a disposition surface parallel to a central axis (C1) and having an optical axis perpendicular to the disposition surface and a pair of side LEDs (2B, 2C). The lens includes a central lens portion (4A) and a pair of side lens portions (4B, 4C). The central lens portion emits light to a central radiation angle range (A1) centering on a central light-emission reference line (L1) along a reference normal line (BN) of the disposition surface. The pair of side lens portions (2B, 2C) emit light to a pair of side radiation angle ranges (A2, A3), respectively, that contain a pair of side light-emission reference lines (L2, L3), respectively, that are inclined mutually-opposite directions at an inclined angle of 60° with respect to the central light-emission reference line (L1). The central lens portion includes a central light incidence portion (32) having a central incidence surface (31) on which light from the central LED is made incident and a plurality of central light guiding portions (33) that branch from the central light incidence portion in the shape of branches and that extend toward the globe side. In each of the central light guiding portions, light that has been refracted and has been made incident from a corresponding incidence region of the central incidence surface onto the corresponding central emission surface is refracted and emitted from the corresponding central emission surface toward a corresponding region of the central radiation angle range.

Disclosed is a switch device including a push operation part having a light transmitting portion, a control board installed in a push operation direction of the push operation part, a fingerprint sensor provided on the push operation part to detect a fingerprint of a user pushing the push operation part, a controller provided on one surface of the control board to control the fingerprint sensor, a flexible board provided to electrically connect the fingerprint sensor and the controller, and a plurality of light sources installed on opposite surfaces of the control board and closer to the push operation part than the controller to illuminate the light transmitting portion.

Eyewear including an optical element, a controller, a support structure configured to support the optical element and the controller, light sources coupled to the controller and supported by the support structure, and a diffuser positioned adjacent to the light sources and supported by the support structure, the diffuser including microstructures that diffuse light emitted by the light sources in a radial anisotropic diffusion pattern or a prism-like diffusion pattern.

A lighting system includes a top housing, a bottom housing, and lens arranged between the top housing and the bottom housing. The lens includes a plurality of side surfaces that extend between the top housing and the bottom housing to form a perimeter of the lens. A plurality of lighting elements are configured to direct an emission of light out of the plurality of side surfaces. A controller is configured to selectively energize the plurality of lighting elements based on a first signal from a GPS module.

A power converter may comprise converter circuitry, a housing and a display. The converter circuitry is configured to convert electrical energy. The housing may comprise a mounting groove. The display may comprise a display screen provided in the mounting groove and a protective layer covering the mounting groove. The protective layer may have a translucent area and an opaque area adjacent to the translucent area. The display screen may comprise a display area located corresponding to the translucent area, and a projection of the translucent area toward the display screen may cover the display area.

Eyewear including an optical element, a controller, a support structure configured to support the optical element and the controller, light sources coupled to the controller and supported by the support structure, and a diffuser positioned adjacent to the light sources and supported by the support structure, the diffuser including microstructures that diffuse light emitted by the light sources in a radial anisotropic diffusion pattern or a prism-like diffusion pattern.

A wearable law enforcement patrol light and signal device including a housing to be worn by a law enforcement patrol officer on a bulletproof vest or on an arm. A high intensity light source is mounted in a front plate of the housing, the high intensity light source electrically connected to a source of electric power in the housing. A switch activates and deactivates the high intensity light source, or the high intensity light source may automatically deactivate. The high intensity light source emits an alternating burst of light of at least five thousand lumens outward when the high intensity light source is activated. The housing of the device also supports a plurality of warning lights, identification badging, a communication system, and other features in a single housing that a patrol officer would normally wear as independent elements.
