Patent number: 11864508Abstract: A lighting system is provided with an illumination device with a semiconductor light emission solution and device suited for plant cultivation in a greenhouse environment are described. A lighting device with binary alloy quantum dots made by colloidal methods produces a size distribution of quantum dots that produces an emission spectrum similar to the photosynthetically active radiation (PAR) spectrum. The methods and arrangements allow more precise spectral tuning of the emission spectrum for lights used in plant cultivation. Therefore unexpected improvements in the photomorphogenetic control of plant growth, and further improvements in plant production are realized.Type: GrantFiled: August 8, 2022Date of Patent: January 9, 2024Assignee: VALOYA OYInventors: Lars Aikala, Ilkka Kivimäki

Publication number: 20210327859Abstract: The present disclosure relates to a method for manufacturing a PCB-less structure for a light emitting unit. The method includes a step of forming a light guide element for the light emitting unit. Electrical components (such as LED components) are embedded to the light guide element and electrical conductors are formed on the surface of the light guide element. An insulating layer in the form of a dielectric layer is then added on top of the components and the electrical conductors. As a result, the light guide element and the dielectric layer form a protective casing around the components and the electrical conductors. The light guide element also serves as a frame for the light emitting unit.Type: ApplicationFiled: April 17, 2020Publication date: October 21, 2021Inventor: Lars AIKALA
