A light source can comprise an optical element, one or more light emitting diodes, and an adjustment. The light emitting diode or diodes can emit light. The optical element can process the emitted light to produce an illumination pattern. The adjustment can change the relative positions of the optical element and the light emitting diodes or diodes, for example by moving some aspect of the optical element or some aspect of the light emitting diode or diodes. The positional change can change the illumination pattern. The adjustment can comprise settings so that the light source can be readily configured to meet predefined application parameters, for example according to IESNA roadway classifications.

A lighting system comprising a track having a first and a second rail (5, 7), mutually extending equidistantly. Said first and second rail comprise a first respectively a second electrically conductive strip, mutually electrically isolated. A lighting module (17) comprising a first and second electrical contact, which lighting module in mounted position rests by gravitational force on the first and second rail. When mounted the first and second electrical contact are in electrical contact with a respective one of the first and second electrically conductive strip. The lighting module is dismountable from the track by a single displacement of the lighting module in a direction against the direction of the gravitational force.

The present invention relates to an illuminated frame system for framing a display unit, such as a screen and the like, comprising a frame on which lighting means, preferably in the form of LEDs, are arranged. An illuminated frame system of this kind may advantageously be used in gaming devices which have at least one screen.

Embodiments include a lighting device that includes a first illumination source comprising a light-emitting diode (LED) of a first color that generates a first light output with a first melanopic ratio of greater than 0.8, and a second illumination source comprising an LED of a second color that generates a second light output with a second melanopic ratio that is less than the first melanopic ratio. The lighting device also includes a light distribution unit for directing and distributing illumination generated by the first and second illumination sources, where at least one of the first illumination source and the second illumination source is affixed to the light distribution unit, and where the first and second illumination sources are oriented relative to one another such that their respective light outputs are directed in different directions.

A simple light-blocking and air-exhausting device includes a ventilation plate and a light-blocking plate arranged oppositely and spaced apart from each other. The ventilation plate is provided with an air vent formed by die-cutting the ventilation plate, and vertical projection of the light-blocking plate on the ventilation plate overlaps the air vent. The vertical projection of the light-blocking plate on the ventilation plate overlaps the air vents on the ventilation plate, so that the light-blocking plate can prevent light from leaking out of the air vents, while air flow can flow out from a gap between the light-blocking plate and the ventilation plate.

The present disclosure provides a lens and an illuminating device employing the same. The lens is an extendable lens, and includes a light incident surface, a light emitting surface, and a first reflecting surface and a second reflecting surface disposed on two sides of the light incident surface respectively. Light enters the lens from the light incident surface at least includes: a first part which is reflected by the second reflecting surface and then directly emits from the light emitting surface, and a second part which is reflected to the second reflecting surface by the first reflecting surface, reflected by the second reflecting surface, and then emits from the light emitting surface.

A strip lamp includes a body, a lampshade, an illuminating component and a holder. The body includes a support wall and a tilt wall. The tilt wall is connected to the support wall's two opposite lateral sides. Also, the tilt wall forms an included angle between the tilt wall's two opposite lateral sides. The lampshade is detachably engaged with the body and is detachably connected to the tilt wall's both lateral sides. The illuminating component is installed on the support wall to face against the lampshade's inner surface. The illuminating component's illuminating span angle is smaller than or equal to the tilt wall's included angle. The holder is detachably engaged with the body. In addition, the holder loads the illuminating component.
