A lens diffusing light emitted from a light source includes a concave light-incident surface, a light guide portion, and a light-emitting surface. The light-incident surface includes a plane portion opposed to the light source and an optical function portion that is formed on the plane portion and one of scatters and diffuses the light. The light emitted from the light source enters the light-incident surface. The light that has entered the light-incident surface passes through the light guide portion. The light-emitting surface emits the light passed through the light guide portion.

The present disclosure relates to a lighting fixture that includes a driver module and at least one other module that provides a lighting fixture function, such as a sensor function, lighting network communication function, gateway function, and the like. The driver module communicates with the other modules in a master/slave scheme over a communication bus. The driver module is configured as a slave communication device, and the other modules are configured as master communication devices. As such, the other modules may initiate communications with the driver to send information to or retrieve information from the driver module.

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.

This new utility invention discloses a waterproof LED lamp comprising a power supply box and an LED lighting module block detachably connected to the power supply box. A power driving board and an LED controller are disposed in the power supply box. The LED lighting module block includes at least one LED module, which includes a module heat dissipater. The power supply box and the LED module are arrayed side-by-side in a parallel manner, and a lateral surface of the power supply box matches a lateral surface of the LED module in size and shape so that the power supply box and the LED module may be in close contact. The power supply box and the LED lighting module block are electrically connected with a conducting wire, which is arranged to go through the wiring hole and the slot. The power driving board provides power to the LED controller and the light board, and the LED controller drives the LED lighting beads on the light board to illuminate. The present invention disposes the power supply and power driver inside a power supply box to separate the power supply from the LED light source. For product maintenance, the power supply or LED light source may be replaced individually.

The invention provides a luminaire comprising an optical element configured to spread light uniformly across a full visible face of the luminaire. The optical element comprises a central region and an outer peripheral region, each configured to receive light emitted by a light source arrangement and to direct this light out through a respective region of the light exit area of the luminaire. The central region receives light through a central transmissive surface portion which partially bounds it across its top. A further reflective tapered portion of the central region acts to reflect light incident at either of its two opposing sides, and provides a mixing function both within the central region of the optical element and within an inner compartment of the luminaire which extends between the optical element and the housing.

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.

The (LED or-and Laser) light source for bulb or light device such as garden light that has at least one of or more than one optics-lens, and light device has one top cover having shape of flat or ½ ball, ⅔ ball, sphere, dome shape for top cover. Foe laser light source incorporate with flat top protective lens and laser film or grating film to enlarge or created plurality of image, lighted patterns. For LED light source can has project assembly which is a built-in or add-on or assembled inside of said light device. Further can incorporated flexible bendable arms to change position, direction, orientation of (LED or-and Laser) light beam. The said Light device also can offer near-by and far-away illumination, or-and lighted image, pattern projection with desired light effects by rotating optic-lens or LED(s). It also can get desired effects while LED(s) controlled by IC or circuitry making LED(s) for color changing or on-off on desired time, duration, cycles. The light device further can have more than one function selected from USB charger, power failure, RF remote control, Infra-red controller, blue-tooth, wifi, internet, App software, motion sensor and wireless with multiple-way communication. Also, light device may have rechargeable circuit, batteries or rechargeable battery, USB ports for the (LED or-and Laser)-bulb be charged or supply other device current.

An optic configuration including a PCBA with one or more LEDs mounted thereon to emit light through a lens and a reflector. The optic configuration may be assembled within a cavity of a lighting fixture. At least a portion of the emitted light may be subtended by the lens, such that the lens may subtend light through a number of regions (e.g., three distinct regions). At least a portion of the emitted light may be subtended by the reflector, such that the reflector may subtend light from a number of surfaces (e.g., four surfaces). At least a portion of the light subtended by the lens may further be subtended by the reflector. The light subtended by the lens and/or the reflector may form a beam pattern including a high intensity spot portion and a lower intensity flood portion.
