The invention provides a lighting device configured to present to an observer a spatially dynamic sparkling light dis play. The device comprises a luminaire containing a plurality of light sources (28) located on a first surface portion, and arranged to direct light in a direction of a plurality of light transmissive areas (32) formed within an opposing second surface portion. The opposing second surface portion may at least partially bound a chamber (14) within which the primary light sources are disposed, where an internal surface arrangement of the chamber is configured to absorb at least part of the spectral composition of any light emitted by the primary light sources which does not fall directly onto the light transmissive areas.

To provide a light device that can suppress the heat influence. In a tail light having LED chips, an electronic component that turns on the LED chips, and a first substrate, and a second substrate, and a third substrate on which the LED chips and the electronic component are disposed, a plurality of the first substrate, the second substrate, and the third substrate are independently provided, and are spaced from one another.

The invention provides a lighting device (12) configured to provide both functional lighting for illuminating a space, and simultaneously to present a spatially dynamic sparkling light display. The device comprises a chamber (14) containing one or more light sources (28). The light sources are arranged to direct light in the direction of a translucent surface portion (20), and in the direction of a plurality of light exit areas (32) delimited by the translucent surface portion. The light exit areas each have a higher transmittance than the surrounding surface portion.

The present invention relates to an illumination device comprising a number of light sources generating light and a number of light collecting means adapted to collect the generated light and to convert the collected light into a number of light beams that propagate along an optical axis. The light sources are arranged in a first group and second group of light sources which are individually controllable. The light collecting means and light sources are displaceable in relation to each other between a first position where the light collecting means collect light from the first group of light sources and convert the collected light into a number of first light beams, and a second position where the light collecting means collect light from the second group of light sources and convert the collected light from the second group of light sources into number of second light beams.

A lamp for a vehicle includes a light generation unit configured to generate light, and a lens configured to change an optical path of light generated by the light generation unit. The light generation unit includes a plurality of array modules arranged in a stacked configuration in which each array module includes a plurality of micro Light Emitting Diode (LED) devices.

An LED light bulb comprises at least one LED light source; a driver arranged in an electrical connection with the LED light source to drive and control the LED light source to emit light; a base electrically connecting the driver to an outside power source; a heat sink provided to dissipate heat generated by the LED light source, having a supporting portion to receive and support the LED light source; a housing joined to the base to accommodate the LED light source, the heat sink and the driver to integrate as a whole. The present disclosure provides an LED light bulb which has an appearance of the traditional incandescent light bulb.

The present disclosure provides a heat sink and an LED light bulb having the heat sink, in which the heat sink is processed by integral bending of a metal plate to form a one-piece structure. The main parts of the heat sink are two spaced side plates and one connecting plate jointing the two side plates. The relative cost is lower than an inblock metal die-casting and the relative shaping process is simpler. Further, the heat sink, an LED light source and other components are accommodated inside a glass housing which is jointed to a base to achieve an overall configuration identical to the traditional light bulbs. Accordingly, the present disclosure makes the structural design of the LED light source more flexible, easier to achieve wide-angle emitting design.

An LED illumination apparatus includes a substrate, a light source disposed on a top side of the substrate, a cover unit configured to cover the light source, and a reflector configured to extend from inside the cover unit towards the upper substrate, such that light generated by the light source illuminates an area below a bottom side of the substrate.

In various embodiments, disclosed is a lighting device comprising a bulbous body mounted on a cap, and an inner surface of the bulbous body comprising a plurality of steps that are axially displaced relative to each other along a central axis of the lighting device. The plurality of steps comprising in one example a first step supporting a first plurality of solid state lighting elements; and a second step supporting a second plurality of solid state lighting elements, wherein the first step is located in between the cap and the second step. A luminaire including such a lighting device is also disclosed. The lighting device may further comprise a bulbous member separated from the cap by a transparent member having a stepped wall profile including the first step and the second step.

An LED lamp includes a mounting seat, a circuit board mounted in the mounting seat, a plurality of primary LED lights mounted on the circuit board, a light permeable frame mounted on the mounting seat, and a shade mounted on the light permeable frame. The mounting seat is provided with a light guide face corresponding to an inner peripheral face of the light permeable frame. The light rays of the primary LED lights permeate through the shade and irradiate downward in a perpendicular manner, and are guided by the light guide face of the mounting seat, pass through the light permeable frame and are diffused and emitted sideward from the shade in an angle of one hundred and eighty degrees (180) to expand the illuminating angle and range of the primary LED lights.
