Said lighting device is made up of lighting elements (L1, L2, . . . , L20) arranged on a mounting board (PS1, PS2, etc.). The one or more boards are arranged so as to supply light with a predetermined coverage.

The boards comprise a plugging system (C1, C2, C3, P1, P2, P3) for connecting said lighting elements. The mounting of such a device using a threaded rod 7 makes it possible to obtain easy maintenance of the device of the invention. This device can easily be used to form striplights.

Use: Lighting of car parks, meeting rooms.

A lighting device, a method of manufacturing a lighting device and a support are described. A support includes a layered structure of alternating conductors and insulating layers. The layered structure includes a mounting section and a body section adjacent the mounting section. The mounting section includes at least one mounting face that has an arrangement direction and at least three alternating contact sections along the arrangement direction. Each contact section is electrically coupled to one of the conductors and separated from a neighboring one of the contact sections by one of the insulating layers. The body section has a width that protrudes sidewards from the at least one mounting face and a length that extends substantially parallel to the arrangement direction.

The disclosure provides a light emitting module and a lighting device using the light emitting module. The light emitting module includes a light source component, and several light guide sheets arranged at a periphery of the light source component, the light source component includes several groups of light source strips vertically arranged, and each group of light source strips is covered with one of the light guide sheets.

A luminaire module delivers light with a beam angle of α. The luminaire module includes a light emitting module and a reflector positioned symmetrically about an axis. Light produced by the light emitting module exits the light emitting module from one or more spatially-extended light emitting portions. The light emitting portion(s) is (are) fully contained within a spatially extended notional design envelope which is used to guide the design of reflector and its corresponding reflective surface, such that when any light exiting the light emitting portions through the design envelope strikes the reflective surface of the reflector, the light does not return to the source and escapes from the luminaire module within a beam angle α, with no more than a single reflection from a reflector.

A light emitting diode (“LED”) light fixture includes a base including contacts for connecting to an electrical power supply, a plurality of LED disposed on a stand coupled to the base, and a protective shell coupled to the base for protecting the stand from being contacted by a foreign object. The LED stand might be an elongated spherical shaped ball, or a polygonally shaped prism.

Examples of the disclosure disclose a heat dissipation structure for a lamp, which includes: a base cup, a supporting top cover, a base cup heat dissipation housing, and a top cover heat dissipation housing. The base cup and the supporting top cover are both made of metal, the supporting top cover is detachably connected to the base cup by interference fitting; and the base cup heat dissipation housing and the top cover heat dissipation housing are both made of thermally conductive plastic. In the present disclosure, the supporting top cover and the base cup are connected to each other by interference fitting to form an internal heat conduction structure; the heat is transferred to the outside by the top cover heat dissipation housing corresponding to the supporting top cover and the base cup corresponding to the base cup.

An omnidirectional LED lamp comprises a light transmission bulb shell, several curved LED modules, a circuit board, and an interface board that connects to LED modules and lamp base. The LED chips are arranged and mounted on the LED module boards so that a uniform light beam with more than a 320 degree wide angle and high rear light flux can be achieved.

Flexible interconnection between substrates, where the substrates include one or more solid state light sources, mounted at varying angles are provided. A multi-dimensional lighting device is formed using such substrates. The multi-dimensional lighting device includes external mounting surfaces, each configured to provide mounting positions for one or more substrates. A flexible jumper device electrically couples a given substrate to an adjacent substrate, and provides a predefined clearance between surfaces of the same and exposed conductive surfaces of the lighting device. Each flexible jumper includes a surface mount device (SMD) capable of being placed by automated process, such as by pick-and-place machines. Such lighting devices are thus possible using automated processes in a high-volume, highly-precise manner.

The disclosed invention is embodied in an improved LED-based lighting fixture for projecting a beam of light having a substantially uniform intensity, rotationally, and a selectable, substantially uniform chromaticity. The lighting fixture includes (1) a concave reflector having circumferential facets, a focal region, an aperture, and a central opening; and (2) a light source assembly including two or more groups of LEDs mounted at the forward end of an elongated, thermally conductive support. The light source assembly is mounted relative to the reflector with the elongated support's longitudinal axis aligned with the reflector's longitudinal axis and with the groups of LEDs located at or near the reflector's focal region. Each of the two or more groups of LEDs includes a plurality of LEDs arranged in a specific pattern such that they cooperate with the faceted concave reflector to project a beam of light having a selectable, substantially uniform chromaticity.
