LED illumination system for the interior of a refrigerated product display cabinet
A lighting system for providing uniform bright lighting of products within in a glass door refrigerated cabinet. The lighting system has a frame member with an angled wing extending therefrom that wraps around a side edge of a light-transmitting optical shield, and a LED lighting strip positioned between the frame member and the optical shield. The LED lighting strip has a plurality of spaced-apart LED lights mounted therealong with a coined reflective facet optic mounted around each LED light. The angled wing(s) reflects light emitted laterally outwards from the at least one LED lighting strip such that the light can be re-directed to evenly illuminate products in a refrigerated cabinet. The angled wing(s) also protects a user's fingers from cracking the plastic optical shield which can become brittle in the cool or cold temperatures of the refrigerated cabinet.
Backlight unit and display device comprising same
The present embodiment comprises: a plurality of light-emitting units; and a reflector including reflector units having spaces formed to receive the plurality of light-emitting units, respectively. Each of the plurality of light-emitting units includes an LED package mounted on a substrate and a light diffusion layer having a groove portion formed on a surface opposite to the substrate in the LED package, wherein the outer circumference of the light diffusion layer faces the inner surface of a reflector unit. In the reflector, the plurality of reflector units are integrally formed, the spaces expand along a direction extending away from the substrate, and a wall forming each of the spaces surrounds the outer circumference of each of the LED package and the light diffusion layer.
CABLE LIGHT
A cable light includes a battery receptacle that is electrically coupled to a first light module and a second light module. The battery receptacle includes a battery port that receives and retains a battery, such as a power tool battery pack. The first light module and the second light module each include a housing supporting a lens, a light emitter such as an LED, a reflector, and a hanger to hang the light modules on a workpiece. The first light module is electrically coupled to the battery receptacle, and the second light module is electrically coupled to the battery receptacle via a connection with the first light module. The battery receptacle communicates electrical power from the battery pack to the light modules to power the light emitters.
Illumination apparatus
A directional illumination apparatus comprises an array of micro-LEDs that may be organic LEDs (OLEDs) or inorganic LEDs and an aligned solid catadioptric micro-optic array arranged to provide a water vapour and oxygen barrier for the micro-LEDs as well as reduced sensitivity to thermal and pressure variations. The shape of the interfaces of the solid catadioptric micro-optic array is arranged to provide total internal reflection for light from the aligned micro-LEDs using known transparent materials. A thin and efficient illumination apparatus may be used for collimated illumination in environmental lighting, display backlighting or direct display.
PHOTOCATALYTIC STRUCTURE CAPABLE OF UNIFORMIZING ULTRAVIOLET LIGHT
A photocatalytic structure that can uniformize ultraviolet lights is provided. The photocatalytic structure includes a housing, a groove formed at a top of the housing, multiple grille slices being engaged with two sides of an inner wall of the groove, multiple grille passages being formed between every two adjacent grille slices, metal meshes disposed on both top and bottom of the grille slices, and a UVC-LED light board disposed at a side of the grille slices. The photocatalytic structure stacks the grille slices to form the grille passages. The UVC-LED light board makes grille passages to reflect the ultraviolet light. More uniform lights are formed at both upper and lower sides of the grille passages. The UVC-LED light board close to the metal meshes ensures the uniform lights to be emitted onto a gap plane with a smaller refraction angle. Therefore, everywhere on the metal meshes are fully illuminated.
LIGHT SOURCE DEVICE AND LIGHT GUIDE ARRAY UNIT
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.
Diving lamp with efficient waterproof performance
An underwater diving light with efficient waterproof performance includes a top cover, a bottom cover, a light-emitting assembly and a special-shaped light-transmitting seal. A first installation groove is formed in the top cover. A second installation groove is formed in the bottom cover. The special-shaped light-transmitting seal includes a light-transmitting waterproof part, a first installation part and a second installation part. The first installation part, the light-transmitting waterproof part and the second installation part are all annular and connected in sequence. The top cover and the bottom cover are movably connected to form a light housing. The light-emitting assembly is arranged in the light housing. The underwater diving light has the advantages of strong waterproof and moisture-proof performance, diversified luminous forms and a dazzling effect.
SYSTEM AND METHOD FOR LIGHT FIELD ILLUMINATOR SHEET-BASED DYNAMIC LIGHTING OUTPUT
A digitally controlled LED illuminator sheet that produces far-field illumination patterns or light field distributions that increase light utilization and application efficiency. A dynamic directional LEDs (or other kinds of solid-state light sources) sheet is positioned under each lenslet of a microlens array. Individual LED beam pointing direction depends on off-axis position relative to optical axis of lenslet. Individual beams from independent LEDs form illumination pixels at the illumination plane or within a volume space and can be modulated in intensity. Illumination pixels partially overlap in far-field illumination plane and illumination volume. Over a large illumination space many illumination pixels will partially superimposed on neighboring illumination pixels, with the overlap being in increments smaller than the size of a pixel. The LEDs can be digitally turned on or off and/or pulse width or amplitude modulated to produce far-field illumination patterns or light field distributions with spectral efficiency and efficacious intensity.
Jewelry Lighting Lamp and a Jewelry Lighting Method
A jewelry lighting lamp has a lighting part, a rotating part and a mounting part, the mounting part has a lamp barrel which accommodates the lighting part and rotating part. The rotating part has a driving motor, which drives the lighting part to rotate along the central axis of the lamp barrel; the lighting part has a main light source arranged on the central axis and one or more secondary light sources arranged around the main light source, the main light source and the secondary light source are driven by the rotating part to rotate along the central axis circumferentially. A jewelry lighting method using the jewelry lighting lamp is also provided. By varying luminance, the lamp solves the problem of visible light and shadows at the edge of the aperture when there are main and auxiliary light sources with different luminance.
