  • Publication number: 20240147598
    Abstract: A method of and a computing device for evaluating lighting quality in a geographic region having a plurality of luminaires arranged therein and a road lighting system are disclosed. Each luminaire in the geographic region comprises a tilt sensor arranged for obtaining a tilt angle of the luminaire. The method is performed by a computing device and comprising the steps of: receiving tilt angles of the plurality of luminaires obtained by tilt sensors of the plurality of luminaires, and evaluating lighting quality in the geographic region with reference to a number of parameters derived from the received tilt angles of the plurality of luminaires.

  • Patent number: 11942456
    Abstract: A method of fabricating a multi-color display includes dispensing a photo-curable fluid over a display having an array of light emitting diodes (micro-LEDs) disposed below a cover layer. The cover has an outer surface with a plurality of recesses, and the photo-curable fluid fills the recesses. The photo-curable fluid includes a color conversion agent. A plurality of LEDs in the array are activated to illuminate and cure the photo-curable fluid to form a color conversion layer in the recesses over the activated LEDs. This layer will convert light from these LEDs to light of a first color. An uncured remainder of the photo-curable fluid is removed. Then the process is repeated with a different photo-curable fluid having a different color conversion agent and a different plurality of LEDs. This forms a second color conversion layer in different plurality of recesses to convert light from these LEDs to light of a second color.

  • Patent number: 11942576
    Abstract: A photocurable composition includes a blue photoluminescent material, one or more monomers, and a photoinitiator that initiates polymerization of the one or more monomers in response to absorption of the ultraviolet light. The blue photoluminescent material is selected to absorb ultraviolet light with a maximum wavelength in a range of about 300 nm to about 430 nm and to emit blue light. The blue photoluminescent material also has an emission peak in a range of about 420 nm to about 480 nm. The full width at half maximum of the emission peak is less than 100 nm, and the photoluminescence quantum yield is in a range of 5% to 100%.
