A portable illumination apparatus having a sterilizing function, the illumination apparatus including: a lamp unit which includes an illuminating light element on an interior side of the lamp unit; a base coupled to the lamp unit by a hinge; and a sterilizing light element located on the interior side of the lamp unit. When the lamp unit is in a closed position with the base, the lamp unit and the base meet at a boundary section to form a cylinder with a top and a bottom. Also, the boundary section is substantially mirror-symmetrical and at least partially U-shaped such that the lamp unit has a longest height line and a shortest height line. Additionally, the illuminating light element is arranged on or along the longest height line and the hinge is formed about the shortest height line.

A light source device includes: a plurality of light source parts configured to emit light, in which each of the light source parts includes a light-emitting element and a light guiding member, the plurality of light source parts are disposed in a circular, planar-shaped placement region and are arranged in (i) a combination of at least a rectangular grid and a triangular grid or (ii) a concentric circular pattern, and the plurality of light source parts are configured to emit the light in a matrix pattern in an irradiated region.

The invention provides a portable lighting device with an elongated main body that includes a housing with receiver, and a power source positioned within the receiver. An operational mode selector assembly with a switch assembly that is actuated by a user is operatively coupled to the power source. An illumination assembly is electrically coupled to both the operational mode selector and the power source. The illumination assembly has a primary light source with a light emitter that emits light axially along a longitudinal axis of the main body or housing through a lens. A secondary light source with a light emitter emits light substantially perpendicular to the axis to illuminate an indicia located in a side region of the illumination assembly. During operation of the portable lighting device, the components of the illumination assembly are arranged such that: (i) the primary light source does not illuminate the indicia, (ii) the secondary light source does not emit light through the lens, (iii) an appreciable amount of light emitted from the primary light source does not mix with light that is emitted from the secondary light source within the portable lighting device, and (iv) an appreciable amount of light emitted from the secondary light source does not mix with light that is emitted from the primary light source within the portable lighting device.

A lighting apparatus includes a top cover, a bottom cover, a light passing cover, a battery, a power circuit, a power switch and a light source plate. The top cover has an opening part for defining a light opening. The bottom cover is fixed to the top cover forming a containing space. The light passing cover has a larger diameter than the light opening. A peripheral edge of the light passing cover engages an inner surface of the opening part of the top cover. The battery is stored in the container space. The power circuit is connected to the battery for providing a current to the LED modules of the light source plate. The power switch is connected to the power circuit to control the LED modules. The light source plate has a top side mounted with multiple LED modules.

Provided is a solid-state illumination system for use in a microscopy system utilizing a light sensor of a mobile phone camera module. The system includes a bright-field illumination source with an array of light-emitting diodes (LEDs). The array of LEDs is configured to produce transmission light within a range of view of the light sensor of the mobile phone camera module. The system also includes a dark-field illumination source including a ring of LEDs. The ring of LEDs is configured to produce light outside of the range of collection of the camera module lens. The system also includes a diffuser configured to diffuse the transmission light and a diffusive black material coupled to the diffuser. The diffusive black material is configured to pass through at least some of the transmission light while blocking reflections of the scattering light.

An illuminated display device for a hollowed-out pumpkin having face holes, the illuminated display device being installable in an inner volume of the pumpkin that is carved as a jack-o-lantern having the face holes and positioned at a front outer surface of the pumpkin, includes: a light bearing substrate; a light source emitting light substantially omnidirectionally, the light source being arranged on the light-bearing substrate; a spike configured to be releasably engageable with an inner surface of the jack-o-lantern to secure the positioning of the lighting device within the jack-o-lantern proximate one of the face holes; and a reflector to direct light from the light source through at least one face hole to provide the impression to a viewer, if the face hole is an eye cutout, that the eye of the jack-o-lantern is following a passerby.

Provided is a fixture including a base; and a light guide, which is positioned on the base and is configured to receive light emitted from a light source in a first direction and guide the received light to be emitted in a second direction crossing the first direction.

An illuminated display device for a jack-o-lantern container having face holes, the device having a light bearing substrate with a front portion, a rear portion, and a slot proximate the rear portion, a light source arranged on the light bearing substrate. The spikes protrude from the front portion of the light bearing substrate and engage an inner surface of the front of the container to secure the device within the container proximate one of the face holes. A reflector plate is positioned in the slot. The slot is oriented with respect to the light bearing substrate to position the plate at an operational angle with respect to the light bearing substrate, with a portion of the light bearing substrate oriented toward the spike and located above the light source, to direct light from the light source through at least one of the face holes.

A portable illumination apparatus having a sterilizing function, the illumination apparatus including: a lamp unit which includes an illuminating light element on an interior side of the lamp unit; a base coupled to the lamp unit by a hinge; and a sterilizing light element located on the interior side of the lamp unit.
