The present invention is directed to an apparatus for providing a light reflector, light fixture, light fixture retrofit apparatus, lamp reflector, lamp retrofit apparatus or luminaire reflector retrofit. According to an example embodiment of the disclosed invention, a light reflector is provided that includes annular segments nested as cone-shaped layers configured for reflecting light from a light source placed in proximity to the inner cone portion. The two or more nested cone-shaped annular segments include a reflective surface. The cone-shaped annular segments are configured such that the segment layer having the smallest aperture is located farthest from the light source.

An LED spotlight includes a lens, a LED light source board and a star shaped or multiple star shaped lighting lined LED light source. The side of the lens is formed as reflective surface. The incident surface is the groove structure of toward away from the sunken of the LED light source. The incident surface includes the first incident portion, the second portion and the transition section between the first incident portion and the second portion. The LED spotlight through setting the incident surface, the exit surface and the reflective surface to become the light allocation structure. The function the light passes through the first incident portion, the second incident portion and the transition section may realize the range between twenty-five degrees and one hundred and twenty in negative degrees adjust. Therefore, the LED spotlight owns the advantage to realize the high efficiency orient light allocation.

Various arrangements for light distribution incorporated as part of a device are presented. A circular light guide may be used that receives light from a plurality of light emitters that can be arranged in a circular pattern. A conical reflector may be used and may be positioned to reflect light emitted from the circular light guide onto an exterior of a case of the device. The conical reflector may reflect light such that light is reflected by the exterior of the case in the shape of a halo into an ambient environment of the device.

An LED floodlight includes a main unit longitudinally formed by extrusion molding and having in one side an opening of a concave groove, and at least one LED unit attached to an inner bottom wall defining the concave groove in the main unit. The main unit is formed on a back side of the inner bottom wall of the concave groove by the extrusion molding and has at least one ventilating duct and open at upper and lower ends. An area having a large heat capacity is provided between the inner bottom wall to which the LED unit is attached and the ventilating duct. The main unit is configured such that the LED unit is turned on in a posture where a longitudinal direction of the ventilating duct defines a vertical direction thereby transferring heat conducted from the LED unit to an airflow going up through the ventilating duct.

According to at least one aspect, a lighting device is provided. The lighting device comprises a circuit board, an LED mounted to the circuit board that is configured to emit light with an angular CCT deviation, a lens assembly mounted to the circuit board over the LED and configured to receive the light emitted from the LED and reduce the angular CCT deviation of the light received from the LED to make a color temperature of the light received from the LED more uniform, and an elastomer encapsulating at least part of the circuit board that is separate and distinct from the lens assembly.

An illumination optical system with a tunable beam angle (IOSTBA) is presented to achieve different beam angles without changing parts. The IOSTBA includes a light source and a post having a proximal end and a distal end, the proximal end in optical communication with the light source, an internal area of the post having a reflective surface. Also shown is a diffuser disposed across the end of the post, the diffuser in optical communication with the post and a reflector surrounding a portion of the post, the reflector movable along a length of the post. A position of the reflector along the post determines a beam angle of a resulting light beam exiting the IOSTBA. The system features a simple and cost effective optical design which works with a variety of light sources, including color mixing and champing strategies.

A luminaire includes a housing defining an interior volume. The luminaire also includes a lamp within the interior volume and configured to emit light. Additionally, the luminaire includes a wireless antenna positioned within the interior volume, configured to transmit or receive a wireless signal along a first direction, and configured to be operatively coupled to an access point. The wireless antenna can be entirely within the interior volume. The luminaire can include a first reflective surface within the interior volume and configured to redirect the wireless signal. The lamp can be configured to be electrically coupled to a power inserter that powers the access point.

According to an embodiment of the present technology, there is provided a bulb-type light source apparatus including a light source unit, a translucent cover, and a base unit. The translucent cover includes a first area including a convex lens function and a second area including a concave lens function. The base unit supports the light source unit and the translucent cover such that the second area is positioned closer to the light source unit than the first area.

An LED lighting array for illuminating an area with the lighting array comprising a plurality of LED devices set in conical or elliptically conical reflectors, each of which is mounted upon a plate, each of which may be set at various angles to one other, and each of which is backed by a series of elements, first a copper support element, then an optional layer of graphite foam, followed by an aluminum plate, and then an arrangement of copper fins operably lined to a thermal mass mate. The copper support element includes support planes that are off-set relative to each adjacent plate and are in at least three different planes relative to each other. The backing plates may efficiently dissipate heat produced by the LEDs. The apparatus can be mounted upon a stand to illuminate an area such as a portion of a car park, building entrance or the like.

The present application discloses a speaker lamp which comprises: a housing is formed with a cavity therein; a radiator is provided within the cavity, and divides the cavity into an upper cavity and a lower cavity; a circuit board is provided within the upper cavity and connected to the radiator, and Light Emitting Diode (LED) light sources are provided on the circuit board; a reflector has an opened upper end and an opened lower end and is hollowed so as to surround a reflector cavity, the lower end of the reflector is connected to the circuit board, and the LED light sources surround an outer side of the reflector; and a speaker is installed at the upper end of the reflector and accommodated within the reflector cavity, wherein within the reflector cavity, a space exists between the speaker and the circuit board. By means of such arrangement, the speaker lamp of the present application is capable of improving lighting efficiency, and improving sound quality.
