A microelectronic package is described with an illuminated backside exterior. In one example, the package has a package substrate, a die attached to the package substrate, a cover over the die and the package substrate, a lamp, and a screen over the die, externally visible and optically coupled to the lamp so that when the lamp is illuminated the illumination is externally visible through the screen.

A motor vehicle headlight with at least one modulable laser light source, whose laser beam is directed onto a means of light conversion through a means of beam deflection controlled by a beam deflection control, and with a projection system to project the light image produced by the means of light conversion onto the road, wherein a first group of at least two laser light sources is provided to produce a first group of at least two essentially horizontal light bands lying on top of one another on the means of light conversion and a second group of at least two laser light sources is provided to produce a second group of at least two essentially horizontal light bands lying on top of one another on the means of light conversion, wherein the light bands of the first group and the light bands of the second group overlap one another.

A light-producing assembly is provided herein and includes a first portion of LEDs biased to direct light in a first direction, a second portion of LEDs biased to direct light in a second direction that is different than the first direction, and a controller for selectively activating the first and/or second portions of LEDs.

A lighting device, in particular a LED lighting device, comprises at least one light source and a reflector extending along and around a longitudinal axis and having an internal reflective surface arranged so as to intercept at least part of the light emitted by the light source and reflect said part towards a light exit opening; the internal reflective surface is a faceted polynomial surface.

A light emitting diode (LED) bulb includes a connecting body, a lamp cap located at a first end of the connecting body, a mounting base located at a second end of the connecting body opposite to the first end, a plurality of LED modules mounted on the mounting base and a sheath assembled to the second end of the connecting body. The sheath includes a first portion and a second portion detachably engaged with the first portion to cooperatively define an enclosed space enclosing the mounting base and the LED modules therein.

The present invention relates to a lighting device (11) comprising a light emitting portion with at least two solid state light sources, SSL (18). The light emitting portion includes a first cover member (12a) with a first light source carrier (13a) and a first light transmitting portion (14), a second cover member (12b) with a second light source carrier (13b) and a second light transmitting portion (14). The first and second cover member are arranged such that a first light transmitting portion is aligned with the second SSL to allow transmission of light emitted from the second SSL through the first cover member, and a second light transmitting portion is aligned with the first SSL to allow transmission of light emitted from the first SSL through the second cover member. According to this design, light emitted from an SSL on one cover member will be transmitted through the other cover member. Dissipation of heat from each SSL may be provided in the other direction, i.e. in a direction opposite to the light emitting direction of each SSL.

Provided are an optical member capable of implementing optical images having desired shapes through a pattern design, and a lighting device using the optical member, the optical member including: a base substrate; multiple patterns sequentially arranged on a first surface of the base substrate and having inclined surfaces with an inclination angle with respect to the first surfaces; and a reflective portion on the base substrate or the multiple patterns, wherein the multiple patterns implement a line shaped beam of a first path crossing at right angles to respective pattern extension directions of the multiple patterns by guiding a first incident beam into a first surface direction toward which the first surface looks or a second surface direction toward which a second surface of the base substrate opposite to the first surface looks, through refraction or reflection from the inclined surfaces.

A device comprising a circuit board, said circuit board having a plurality of LEDs dispose on said circuit board, and a chassis, said chassis having a plurality of baffles, each baffle formed by bending a portion of the chassis substantially orthogonally to the surface of the chassis leaving a plurality of holes in said chassis, said holes spaced substantially the same spacing as the plurality of LEDs. The baffles may operate to shield light emitted from the LEDs to either 30 degrees, 45 degrees or 60 degrees. Also included is a housing operable to secure the circuit board and chassis into a fixed position.

Provided is a top plate for a cooking device including a glass sheet (2) and a light-shielding film (3) formed on a lower surface (2c) of the glass sheet (2) through sputtering. The light-shielding film (3) contains an oxide, a nitride, or an oxynitride of a transition metal of Group 6 to Group 11 on the periodic table. In this manner, a color close to grey can be achieved as a color of the light-shielding film (3) while insulating properties of the light-shielding film (3) are secured.
