LIGHT EMITTING DEVICE
A light emitting device includes one or more light emitting elements, a light transmissive member, a first light reflective member and a second light reflective member. The light transmissive member is disposed on the one or more light emitting elements and having a first upper surface, a lower surface, first lateral surfaces, and second lateral surfaces each positioned on an outer side of a corresponding one of the first lateral surfaces. The first light reflective member covers the first lateral surfaces. The second light reflective member is disposed on lateral surfaces of the first light reflective member, the second lateral surfaces of the light transmissive member, and lateral surfaces of the one or more light emitting elements.
Light emitting diode (LED) based lighting systems
A lighting system comprises at least one excitation source (5), preferably an LED, operable to generate and radiate excitation radiation of a first wavelength (λ.sub.1); a shade (4) configured to at least in part surround the at least one source (5) and remotely located thereto; and at least one phosphor (16) provided in or on at least a part of the shade (4), wherein the phosphor (16) emits radiation of a different wavelength in response to incident excitation radiation. The phosphor can be provided on a part of an outer or inner surface of the shade. Alternatively, or in addition, the phosphor is incorporated within the shade. The lighting system finds particular application as a hanging, a desk, a floor standing, a wall mountable, a spot, an outdoor or an accent lighting fixture.
PHOSPHOR PLATE AND LIGHTING DEVICE INCLUDING THE SAME
An embodiment of the present invention relates to a phosphor plate, which is a plate-shaped photo-conversion structure in which a phosphor is dispersed inside of a glass matrix, and has an uneven surface comprising at least one type of pattern, formed on at least one surface of the both surfaces of the plate, wherein the pattern occupies 70-95% of the area of the one surface.
Interior side marker
A vehicle includes a seat assembly having a seatback and a seat base. A side marker is positioned on the seat base. A light assembly is configured to emit light toward the side marker. The side marker emits light to an exterior of the vehicle when the vehicle is in a doors off configuration.
Light emitting device
A light emitting device includes a base having a light reflecting surface and having a first side on which the light reflecting surface is provided, light sources mounted on the first side, and a half mirror disposed opposite to the base to reflect a part of incident light and to transmit another part of the incident light. Each of the light sources includes a reflecting layer on an upper surface of each of the light sources. The half mirror has an oblique reflectance with respect to wavelengths of light emitted from the light sources in a case where the light travels obliquely toward the half mirror. The half mirror has a perpendicular reflectance with respect to the wavelengths in a case where the light travels perpendicularly toward the half mirror. The oblique reflectance is smaller than the perpendicular reflectance.
