A lighting device has a power interface and a control circuit in communication with a program and the LEDs to simulate a flame. The program determines a first group of LED control integers to simulate a perpetual middle with a perpetual middle center and a perpetual middle range within which one or more of the LEDs are to be at least partially actuated. At least one LED is actuated based on the first group of LED control integers. A first target for simulating movement of the perpetual middle center toward the first target and a first acceleration value is defined. The program determines a second group of LED control integers based on the first target and the first acceleration value such that the perpetual middle center becomes closer to the first target. One or more of the LEDs is actuated based on the second group of LED control integers.

A system (100) and method (900) for illuminating the interior space (90) of a trailer (84). The system (100) can utilize a power box (200) to draw and store electricity from a tractor (82) and use that electricity to activate LED assemblies (300) within the trailer (84) is untethered from the tractor (82). The lights (310) can be activated by a motion sensor (340) associated with the location of the lights (310) being activated.

The skin therapy device combines the mechanical stimulation and cleansing in the form of vibration with optical stimulation from LEDs. The device combines these two elements without sacrificing the effectiveness of either the mechanical cleansing/stimulation or optical stimulation by passing the light through the mechanical elements that are in contact with the skin. The light from the LEDs does not pass around the mechanical elements, such as around opaque brush fibers, but passes through the mechanical elements.

The second convex lens is arranged on the first rotating assembly and located on a side of the first pattern sheet towards the first convex lens. The second convex lens receives the light pattern and generates an analog 3D pattern. The first rotating assembly drives the second convex lens to rotate, which can achieve movement and focusing of the plurality of 3D patterns, project the patterns with a plurality of 3D effects, and enable a user to quickly immerse among the patterns, thereby improving the user's experience.

A vehicular exterior rearview mirror assembly includes a mirror reflective element sub-assembly having a mirror reflective element, a mirror reflector, a mirror back plate, and indicator element. The indicator element includes a housing and a light source. The indicator element is associated with a blind spot detection system of the vehicle and includes a diffuser that diffuses light emitted by the light source. An icon is established through a metallic reflector coating disposed at the glass substrate. The icon includes a light-transmitting aperture. When the vehicular exterior rearview mirror assembly is attached at the vehicle, the icon is at an upper quadrant of the mirror reflective element. When the vehicular exterior rearview mirror assembly is attached at the vehicle and when the light source is activated, the icon is illuminated and is viewable by the driver of the vehicle.

A white light source includes a light source and a phosphor conversion component. The light source emits short wavelength light peaked at a peak wavelength of 570 nanometers or shorter. The phosphor conversion component includes a light conversion layer comprising a phosphor effective to convert the short wavelength light to converted light. The light conversion layer includes light passages comprising openings or passage material that does not comprise the phosphor and is light transmissive for the short wavelength light. The light source is disposed respective to the phosphor conversion component so as to illuminate the light conversion layer with the emitted short wavelength light and to pass the short wavelength light through the light passages.

A light control apparatus includes a diffuser plate, a light source, a light pipe, and a light blocker. The diffuser plate includes at least one opening therein. The diffuser plate includes feature located around the opening in the diffuser plate that exposes a portion of the diffuser plate. A light source positioned proximate a second surface of the diffuser plate is optically coupled to a light pipe positioned around a portion of the opening near the second surface of diffuser plate. A light blocker is positioned near a second portion of the at least one feature. The light blocker is positioned between the light source and the second portion of the feature, the light blocker having an opening therein to allow light to pass from the light source to the diffuser plate proximate the second portion of the feature.

Disclosed are methods for forming a double-sided optical sheet, and a vehicle lamp assembly having the double-sided optical sheet integrated therein. A first optical pattern is imprinted on a first side of a material, and a second optical pattern is imprinted on a second side of the material, opposite the first side. The first and second optical patterns are thereby formed on opposing sides of the same sheet. When oriented adjacent a light source, the double-sided optical sheet homogenizes light emitted from the light source. For a light source having a plurality of lighting elements, the double-sided optical sheet is configured to blend light emitted from the plurality of lighting elements to form one homogenous beam of light output resulting from a single light-modifying member.
