An optoelectronically functional multilayer structure as well as related methods of manufacturing an optoelectronically functional multilayer structure are described herein.

A projection system for a vehicle, in particular for an ambient lighting device for generating a plurality of light cones for illuminating the ground in the surroundings of the vehicle, includes at least one light source and a microlens array. The microlens array includes an optical axis, a first portion with at least one first channel and a second portion with at least one second channel. The projection system includes an optical device that is provided downstream of the microlens array and is arranged at least in the area of the first portion, with the distance between the microlens array and the optical device being less than 20 mm. Light emitted by the light source, which falls through the at least one first channel of the first portion, is deflected by the optical device by a first angle with respect to the optical axis and forms a first light cone, and light emitted by the light source, which falls through the at least one second channel of the second portion, is deflected by a second angle with respect to the optical axis, which differs from the first angle, and forms a second light cone.

Ultraviolet (UV) light emission devices employing UV light source housing to achieve UV light emission irradiance uniformity, and related methods of use. The UV light emission devices disclosed herein are particularly suited for use in disinfecting surfaces and air. The UV light emission devices disclosed herein can be provided in the form factor of a handheld device that is easily held and manipulated by a human user. The human user can manipulate the handheld UV light emission device to decontaminate surfaces, air, and other areas by orienting the handheld UV light emission device so that the UV light emitted from its light source is directed to the area of interest to be decontaminated.

A pointer includes a case housing an LED device and including a light emission hole through which light from the device is emitted to an external space, a first plate between the device and the light emission hole and including a first light passage hole that allows passage of the light from the device, and a second plate between the first plate and the light emission hole and including a second light passage hole that allows passage of the light having passed through the first light passage hole. The light passage holes and the light emission hole are located on a central axis of the device. The device and the first and second plates are disposed such that H/2<S<H, where H denotes a distance between the device and the first plate, and S denotes a distance between the first and second plates.
