A combination axial fan and LED lighting system configured to fit into the footprint of a standard ceiling tile. The system includes a housing container and an axial fan. The fan has a fan cavity including air diversion mechanism to direct air from the fan cavity toward the lighting and fan components. The invention includes an airflow surface to direct air existing the fan cavity along an LED light fixture.

A lighting device may include a channel-shaped elongate housing with a web portion and two side portions extending along the elongate housing sidewise of web portion, wherein each side portion includes, facing inwardly of the channel shape of elongate housing, a proximal groove extending sidewise of web portion, one or more electrically conductive lines extending along web portion internally of the channel shape of said elongate housing, and a light radiation source assembly. The light radiation source assembly includes a support board having a back surface facing web portion of elongate housing with respective electrically conductive lines in order to make electrical contact with said electrically conductive lines and a front surface facing outwardly of the channel shape of elongate housing, and at least one electrically-powered light radiation source, on said front surface, being in electrical contact with said electrically conductive lines.

A light emitting apparatus includes at least one first light source and at least one second light source. The at least one first light source and at least one second light source may be configured to emit white light and cyan light, respectively, such that a ratio of luminous flux of the white light to luminous flux of the cyan light ranges from 19:1 to 370:1, based on a common magnitude of electrical current being applied to each of the at least one first light source and the at least one second light source.

A roadway fixture system includes a lighting fixture having an outer housing that holds one or more light devices. The outer housing includes an access door through which an interior of the lighting fixture is accessible. The system also includes a radio frequency (RF) transceiver configured to send and receive cellular communications. The RF transceiver includes a mounting plate that is sized and shaped to fit into a space occupied by the access door of the outer housing of the lighting fixture so that the RF transceiver is mounted to the lighting fixture.

A lighting device may be provided that includes: a body; a first light source and a second light source, which are disposed on the body and are disposed symmetrically with each other with respect to a central axis of the body; a first light guide unit which is disposed on the first light source and is coupled to the body; and a second light guide unit which is disposed on the second light source and is coupled to the body. The first light guide unit and the second light guide unit are disposed symmetrically with each other with respect to the central axis of the body.

An adjustable LED lighting fixture which accommodates LED lights of varying lengths. The LED fixture has a central body element, and two movable end elements movably attached to two opposing sides of the central body element and extend in a direction normal to a length of the fixture. The two end elements face each other with LED pin sockets facing each other whereby an LED tube light is able to be operationally inserted into the LED pin sockets. Two slidable elements are attached to the end elements and extending in a direction in a direction along the length of the fixture and toward the other of the end elements and through a retention element. The slidable elements permit the expansion and contraction of the length of the LED fixture, by sliding relative movement toward and away from the other of the end elements, to hold LED light tubes of varying lengths.

The present invention discloses a laser stimulated white light lighting system, it includes a hemispherical reflector, a light-permeable board, a wavelength conversion layer, a reflective layer and plural heat-radiating structures, wherein the laser light emitted by a laser light source passes through a first light entrance hole of the hemispherical reflector and subsequently through the wavelength conversion layer to produce white light. With the implementation of the present invention, complex production process or equipment is not required thus reduce the system cost, the lighting system is capable of accurately outputting white light and promoting photon recycling effect to raise illumination efficiency. With the addition of a second light entrance hole, wavelength-division or angular division multiplexing can be carried out to raise the intensity of the output white light without increasing the etendue of the source light, thereby widening the range of application of the lighting system.
