The present invention relates to an optical device that enables the projection of the light to be controlled such that it comes out parallel to a non-active multi-cell shielding device, wherein said shielding device is not illuminated by the light beam, the user perceiving the light with all its intensity, without loss of intensity due to the reflection of said shielding device, wherein furthermore, due to the low profile thereof, the optical device enables same to be integrated into a luminaire with a reduced height dimension, which is also object of the present invention.

The light fixture connects a separable cage to a that may directly mount to the wall of a structure or which may mount to the structure through a wall plate. The cage has a frame with a roof and an open rear side that receives the backplate. A lighting assembly is connected to the front face of the backplate and is thereby housed within the interior of the cage when the unit is assembled and which can be accessed when the cage is removed. To removably attach the cage to the backplate, an aperture is provided within a ledge in the backplate that receives a tab to suspend the cage from the backplate fixedly connected to the supporting structure. Thus, the lighting assembly can be accessed by separating the cage from the backplate.

A submersible marine lighting apparatus is provided which converts electrical input to 25 or 34 volts and provides optimal underwater illumination. The marine lighting apparatus comprises a plano-convex light-focusing lens that concentrates emitted light into a more focused beam, as well a thermal switch and COB LED.

In various embodiments, a light emitting diode (LED) lamp is provided. The LED lamp may include a base; a first housing having a first end and a second end, the first end secured to the base; a second housing having at least in part a partially conical shape, an end of the second housing having a smaller diameter secured to the second end of the first housing; at least one LED secured within the second; driver circuitry secured within the LED flood lamp between the end of the base and the at least one LED; a reflector having a partially conical shape; and a diffuser element secured to at least one of a wider end of the reflector or the end of the second housing having the larger diameter. In some embodiments, the first or second housing may include one or more vents.

At least two lighting modules are disposed on a printed circuit board (PCB). Each of the lighting modules includes a plurality of light emitting diode (LED) chips disposed in a non-rectangular array. Lenses are provided over the lighting modules. Each lens has a convex outer surface, and a chamber with a planar or concave inner surface facing a corresponding lighting module and disposed to cover the LED set within the chamber. A light projecting device includes a plurality of LED sets and a plurality of lenses. An orientation part couples each lighting module to the PCB at a non-zero angle.

Disclosed is a luminaire such as an LED downlight which is suitable for mounting in ceiling cavities of commercial environments. An example luminaire (200) comprises a light source (202) including an integral primary optic which is configured to transmit light toward a second optic (214). The second optic (214) is a lens configured to receive light from the light source (202) via the primary optic and transmit at least part of the received light toward a circular reflector (201). The circular reflector (201) is configured to direct light received from the second optic (214) away from the luminaire (204). A shape of the second optic (214) is interdependent with a shape of the circular reflector (201), and the shape of the second optic (214) and circular reflector (201) act in combination to transmit light away from the luminaire with a non-circular illuminance distribution (206).

A light source device includes: a light source having an upper surface including a light-emitting surface, the light source including a plurality of light-emitting parts arranged in a two-dimensional array; a lens located above and spaced apart from the light-emitting surface of the light source, wherein the lens includes an optically functional part, and a flange part located along an outer periphery of the optically functional part; and a support part formed of a light-shielding member and configured to support at least the flange part of the lens.

The present invention discloses a sector light, said sector light having at least one tier including a light source assembly comprising opaque dividing elements, two or more light sources, and two or more optical lenses; wherein the light source assembly is divided into circumferential sections, each circumferential section being separated by the opaque dividing elements, and each circumferential section containing a light source and an optical lens arranged such that the optical lens collects and outwardly projects the light emitted by the light source.

The present invention relates to a lighting device for the complete and precise projection of a light beam comprising a light source, a plate and a light focusing system, the plate comprising an aperture, the light source and the light focusing system being on a first side of the plate, the light source and the light focusing system being configured for projection of a light beam from the aperture, the light focusing system comprising a collimator, two biconvex and one biconcave lenses. The invention also relates to a method for completely and precisely illuminating an object or space through an aperture.

A variable-focus lighting device and a variable-focus lighting system have one light source and are used to adjust the position and focus of light that is emitted, among various positions in an interior space. An installation space on an interior roof is reduced and manufacturing costs are reduced.
