A zoom lamp includes a lamp body, a light emitting component, a movable ring, a lens, and a rotation ring. The lamp body defines a receiving groove. The movable ring includes a plurality of guiding posts protruding from an outer wall thereof and a plurality of resilient members. The lens is fixed to the movable ring. An external wall of the rotation ring is provided with a latching hook, the rotation ring defines a plurality of inclined grooves. When the rotating ring rotates, the guiding post is guided by the inclined groove to slide, thereby driving the lens to move adjacent to or away from the light emitting component.

This disclosure discloses an illumination apparatus. The illumination apparatus comprises a cover comprising a second portion and a first portion, and a light source disposed within the cover. An average thickness of the first portion is greater than that of the second portion.

An LED bulb structure includes a glass envelope, support, LED light emitting body, tungsten filament light emitting body and electronic element units, where the glass envelope is vacuum-sealed, the support formed by a conducting wire is fixed inside it, both LED and tungsten filament light emitting bodies are configured on the support, the necessary electronic element units are configured on the support between the LED light emitting body and tungsten filament light emitting body, and one side of the support is set to a positive pole and another side thereof a negative pole. As arranged, air will enter the glass envelope of a broken LED bulb to cause the tungsten filament to be burned to break to extinguish, and thus to cause the LED light emitting body to extinguish in such a way to remind users that the broken LED bulb must be replaced with a new one.

A light fixture is provided with a heating element. The heating element can be a resistive heating element, such as a Nichrome wire, and resides in grooves of a cover (e.g., a glass globe) of the light fixture. Thus, the heating element acts to directly heat the cover of the light fixture to prevent, decrease, or otherwise correct frosting, freezing, and other elemental effects on the cover when it is exposed to the environment. The heating element is capable of raising the temperature of the cover at least 15° C. from an initial temperature of −20° C. in 30 minutes. A heat sensing element may provide feedback regarding the temperature of the cover for controlling power supplied to the heating element.

The present invention relates to a lighting device (1, 2, 5, 6) comprising a hollow and translucent envelope (12, 22, 52) connected to a base (13, 23, 53); a light mixing element (10, 20, 30, 50, 60) arranged within the envelope (12, 22, 52); and at least one light emitting diode (11, 21, 31, 51) arranged within the envelope (12, 22, 52), arranged to emit light into the light mixing element (10, 20, 30, 50, 60) and arranged in thermal contact with the light mixing element (10, 20, 30, 50, 60). The light mixing element (10, 20, 30, 50, 60) comprises a thermally conductive and translucent ceramic material. The light emitted from the light emitting diode (11, 21, 31, 51) is mixed within the light mixing element (10, 20, 30, 50, 60), distributed from the light mixing element (10, 20, 30, 50, 60) through the thermally conductive and translucent ceramic material, and transmitted through the translucent envelope (12, 22, 52). The present invention also relates to a luminaire comprising such a lighting device (1, 2, 5, 6).

The invention refers to a lighting automatic system for pedestrian crossing and to a method of making the markings for the pedestrian crossings. The system comprises several lighting units sank in the asphalt made of a box (2) welded by a netting (11) fixed on the bottom of the hole made for the mounting of the lighting units, the box (2) having an external frame (5) and being closed with a detachable cap (4) equipped with a window in which a protection frame is fixed (6) of a piece made of safety glass (8), the cap representing the transversal marking of the pedestrian crossing, in the interior of the box (2) being a LED lighting unit (1) powered by a net or a photovoltaic plant (14) mounted on a pile (17) in the proximity of the pedestrian crossing, on the surface of the cap (4) being poured bitumen subsequently painted with reflecting painting, so that the glass (8) in the mounted state of the system, to be at the level of the roadway (10).

A modular light assembly having a control housing surrounding a power driver and at least one modular component. The modular component includes two side portions, a plurality of ribs extending between the two side portions to form a grated portion, and a flat portion configured to receive a COB LED. The lighting assembly may also comprise a video assembly having a camera and control circuitry provided within the lighting and video assembly for remotely controlling the camera.

A lamp and an operating method for a lamp with an LED element 22 are described. An electrical circuit with the LED element 22 is covered by a cover member 12. A separation device 28 is provided to mechanically severe the electrical conductor 16a, 16b arrange to supply electrical power to the LED element 22 if the detector element 24 detects a defect of the cover member 12.

Disclosed is a sound absorbing lighting panel (100) comprising a sound absorbing member (120); an optical medium (130) over said sound absorbing member; a first set (140) of solid state lighting elements (142) arranged along a first edge of said optical medium; a translucent sheet (150) over the optical medium, said translucent sheet having a non-uniform degree of translucency such as a higher degree of translucency over a central region of said optical medium than over a first region of said optical medium comprising said first edge. A modular surface system including such a sound absorbing lighting panel is also disclosed.

A Cast Guard Unit (CGU) light fixture is suitable for dry and wet areas and seals a wiring cavity using a single O-Ring. A cylindrical projection of the CGU center telescopingly engages a cylindrical cavity in the CGU top to varying depth and flanges on the CGU center and CGU top sandwich a light shade. The engagement of the cylindrical projection into the cylindrical cavity is free to vary to accommodate varying thicknesses of various light shades. The O-Ring resides between the cylindrical projection and the cylindrical cavity sealing the wiring cavity.
