White light LED light bulbs for ambient lighting and pathogen inactivation
11628234 · 2023-04-18 · ·

Consumable and replaceable light bulbs that emit white light to provide ambient lighting and also emit UV light for pathogen inactivation. The white light and the UV light may be emitted simultaneously or the light bulb can be controlled to emit the white light and the UV light at separate times. The UV light emitted by the light bulbs has a wavelength and output power that is safe for humans and pets and the UV light inactivates pathogens over relatively prolonged exposure periods. The light bulbs described herein can be used in place of conventional light bulbs, for example in a room of a home, office building or other human occupied space. Humans can remain in the space when the light bulb(s) is on without being harmed by the UV light.

Light box apparatus

A light box includes a light passing cover printed with an image. The image is being logically divided into two-dimension blocks. The light box includes multiple light tubes. Each light tube includes a tubular housing, an elongated LED bar, and a controller. The elongated LED bar is being enclosed by the tubular housing. The elongated LED bar has multiple LED modules divided into multiple LED sections. The multiple light tubes is being disposed behind the image of the light passing cover. The multiple LED sections of multiple light tubes is being corresponding to the two-dimension blocks of the image respectively. The controller controls the multiple LED sections separately according to a stored script. The stored script indicate a timing sequence for controlling the multiple LED sections for illuminating the two-dimension blocks of the image according to the stored script.

Replaceable vehicle light

The present invention may include a replaceable vehicle light including a lamp body, a printed circuit board (pcb) supported by the lamp body, and the pcb may include a plurality of individual lights arranged in a radial pattern. A controller chip may be included on the pcb, the controller chip may provide electrical energy to each of the individual lights, thereby enabling selective illumination of each of the individual lights. The controller chip may provide a lighting designation, wherein some of the individual lights are designated as primary lights being illuminated at a first brightness, which may illuminate in a radial pattern. The radial pattern may provide a more visible pattern which may be more distinguishable from other roadway lighting, thereby increasing visibility of the replaceable vehicle light.
