The master power controller can be coupled to the circuit board and can be configured to control power provided to the LED clusters.

A light bulb apparatus includes a light bulb shell, a bulb head, and a heat sink cup. The heat sink cup has a first end connected to the light bulb shell, and a second end connected to the bulb head. The light bulb apparatus includes a flexible filament and a central support. The flexible filament has a first terminal and a second terminal, and the central support provides a first electrode electrically connected to the first terminal, and provides a second electrode for electrically connected to the second terminal. The light bulb apparatus includes an expanding structure and a driver module. The expanding structure is mechanically coupled to the central support, and includes a plurality of holding portions for holding the flexible filament. The driver module is electrically connected to the bulb head and the central support for providing electrical power to the flexible filament.

Side light LED troffer tube. In an aspect, a side light LED tube is provided that includes a tube having at least one light receiving portion configured to receive light and gradient optics formed on the tube. The gradient optics providing a transparency gradient configured to distribute the light to achieve a selected emitted light intensity variation across a selected surface of the tube.

A lighting device is disclosed in the present disclosure. The lighting device includes a support assembly, an illuminant assembly, and a switch assembly. The illuminant assembly is connected to the support assembly and capable of being rotated to the support assembly. When the illuminant assembly is rotated to a position at which an angle between the illuminant assembly and the support assembly is less than or equal to a first angle threshold, the switch assembly turns to an on-state. In this way, the lighting device has a function of a switch.

Light bar assemblies configured to be mounted at a rim of a steering wheel of a vehicle are disclosed. The light bar assemblies can include components of a driver monitoring system. The light bar assembly includes a PCB bar having a plurality of visible and infrared LEDs and a LED driver. The PCB bar is coupled to a support plate of an outer shell surrounding the PCB bar. The support plate transfers heat generated by the LEDs and LED driver away from the PCB bar.

An illumination device includes multiple light-emitting elements operatively arranged to emit light during operation, and a transparent elongate optical element including one or more cavities. The optical element is arranged to receive light from the light-emitting elements. The one or more cavities are arranged along an extension of the optical element.

One or more slit arc-shaped (vertex) illuminators (SAVI) have unique interactions when illuminating objects, especially convex or concave curves on spheroidal objects such as the human face creating proximity dependent enhanced dynamic illumination. When multiple SAVI are used, with adjoining vertices, adjustments made to the intensity of individual SAVI dramatically change the visual appearance of convex and concave radial curves shapes on the subject. In portrait photography, the illumination balance of opposing SAVIs offers novel controlled distortion that adjusts facial contours to achieve a desired effect, e.g., apparent thinning or other esthetic goals. When photographing different human skin types (light vs. dark tones) the arc geometry of the beams also manipulates the BDRF (Bidirectional reflectance distribution function) rendering evenly distributed illumination boundaries while also avoiding distortions (toroidal or curvature flattening) associated with other illumination shapes such as squares, rectangles, or circles.
