Light emitting device (LED) circuit board layouts for low profile lighting fixtures are provided. In some embodiments, the lighting fixture can include a fixture housing. The lighting fixture can include one or more LED devices disposed on a circuit board. The lighting fixture can include one or more electronic components associated with at least one of a driver circuit or a filter circuit (e.g., as part of a flicker reducing circuit) disposed on the circuit board. The one or more LED devices are disposed on a first portion of the circuit board and the electronic components are disposed on a second portion of the circuit board. The second portion of the circuit board can be spaced radially apart from a center point of the circuit board relative to the first portion.

A downlight comprising a back cover, a LED light panel, a hollow ring, and a diffuser panel is provided. A bottom and a sidewall of the back cover constitute an accommodation space. An end of the sidewall away from the bottom has an opening. The LED light panel is disposed at the bottom of the back cover. The hollow ring is disposed at the opening of the back cover. An inner sidewall of the hollow ring extends along an axis of the hollow ring, and is made of light-transmitting material, allowing light from the LED light panel to pass through. The diffuser panel is disposed at a hollow of the hollow ring. The downlight of the present disclosure can present one or two glowing rings, and the hollow ring can either emit light from the entire surface or just from the two sidewalls, meeting different lighting needs and aesthetic preferences.

A backlight panel is provided, which includes a substrate including first and second light-emitting areas, first light-emitting devices arranged in rows and in columns in the first light-emitting area, and second light-emitting devices arranged in rows and in columns in the second light-emitting area. The first light-emitting area overlaps the center of the backlight panel. The second light-emitting area is located on a side of the first light-emitting area. A first coincident boundary is formed between the first and second light-emitting areas, and a second coincident boundary is formed between the second light-emitting area and the backlight panel. In the row direction, the distance between at least one second light-emitting device closest to the second coincident boundary and another adjacent second light-emitting device is less than a distance between any two adjacent first light-emitting devices.

Some embodiments of the present light fixtures include a body, a waveguide, and one or more independently-controllable light sources. The waveguide is configured to be coupled to the body and may include a first end configured to receive light emitted from at least one of the light source(s) and to direct the received light to (and in some embodiments, emit the received light from) a second end of the waveguide. In some embodiments of the present fixtures, the waveguide defines an opening through which light emitted from at least one of the light source(s) can pass, the light source(s) being coupled to the body such that a first one of the light source(s) emits light into the first end of the waveguide and a second one of the light source emits light through the opening.

A lighting device according an aspect of the current disclosure includes a sensor that emits and receives signals to detect object, and a light source module disposed on the sensor, wherein the sensor transmits and receives the signals through the light source module, wherein the light source module includes a substrate, a light source disposed on the substrate, and a resin layer disposed on the light source, and wherein a distance between the sensor and the light source module is about 60 mm or more.

A luminaire or lamp (10) with an umbrella-like lamp body (16), wherein the lamp (10) has at least one lighting element (20) integrated into the lamp body (16), which in the position of use emits light at least in one downward direction. The lamp body (16) has on its underside a conical stem-like element (28), which is used to fixate the lamp (10) above the neck opening (14) of a commercially available bottle (12) is formed, the light source being arranged in a ring or wreath shape around the stem-like element and preferably above it. The lamp (10) may be easily be fixed for example in standard wine or spirit bottles and provides glare-free and effective lighting for both the bottle itself and the surrounding area.

The disclosed device relates to a multiple lighting mode LED lamp. The lamp has an LED assembly with a plurality of white LEDs for a first illumination source, and a plurality of UV LEDs for a second illumination source. The LED assembly is attached to the first end of a flexible support, and a base is attached to the second end of the flexible support. The lamp base incorporates an LED driver module in electrical communication with the illumination sources. A manual touch switch in the base, when touched by a user activates the white LEDs to operate the lamp in a lighting mode. A motion sensor in the form of an infrared induction sensor, is incorporated into the face of the LED assembly for detecting motion. Upon motion being detected, the UV LEDs are activated for a predetermined period of time to operate in UV light mode.

An apparatus provided with a lighting device, including a lighting device disposed along a first face of the apparatus, an in-line portion that is at a position in line with the lighting device, and an exposing portion that is provided at the in-line portion and that exposes an end face of the lighting device.

Embodiments of the present invention provide electronics housings that house drivers and other electronics for powering/controlling light sources within a light fixture. The electronics housings are designed to physically isolate the electronics housed within and improve contact between the housing and the electronics to create direct thermal paths for heat dissipation. Heat sink fins may be provided on the electronics housings to create air passageways through which air can move to remove heat from the electronics housings and the light fixtures to which they are attached.
