Publication number: 20190326488Abstract: A light emitting diode module comprising: at least one light emitting diode structure, an integrated reflector arrangement that comprises a reflector surface for reflecting light from a light emitting area of the light emitting diode structure. The integrated reflector arrangement further comprises a back reflection surface for diffusely reflecting light emitted via a side surface of the light emitting diode structure back to the light emitting diode structure. The back reflection surface is directly attached to at least a part of the side surface such that during operation of the light emitting diode module an emission of stray light by means of the side surface is reduced. The invention further describes a corresponding method of manufacturing such a light emitting diode module. The invention finally describes a flash module, an automotive front lighting or a projection light emitting diode system comprising at least one light emitting diode module.Type: ApplicationFiled: December 8, 2017Publication date: October 24, 2019Applicant: Lumileds LLCInventors: Grigoriy BASIN, Anton BELYAEV, Lex KOSOWSKY, Yi Shyan GOH

Publication number: 20190172983Abstract: A ceramic green wavelength conversion element (120) is coated with a red wavelength conversion material (330) and placed above a blue light emitting element (110) such that the ceramic element (120) is attached to the light emitting element (110), thereby providing an efficient thermal coupling from the red and green converters (330, 120) to the light emitting element (110) and its associated heat sink. To protect the red converter coating (330) from the effects of subsequent processes, a sacrificial clear coating (340) is created above the red converter element (330). This clear coating (340) may be provided as a discrete layer of clear material, or it may be produced by allowing the red converters to settle to the bottom of its suspension material, thereby forming a converter-free upper layer that can be subjected to the subsequent fabrication processes.Type: ApplicationFiled: February 11, 2019Publication date: June 6, 2019Applicant: Lumileds LLCInventors: April Schricker, Kim Mai, Grigoriy Basin, Uwe Mackens, Joost Vogels, Aldegonda Weijers, Karl Zijtveld

Patent number: 10153404Abstract: In one embodiment, a solid cylindrical tablet is pre-formed for a reflective cup containing an LED die, such as a blue LED die. The tablet comprises uniformly-mixed phosphor particles and transparent/translucent particles of a high TC material, such as quartz, in a hardened silicone binder, where the index of refraction of the high TC material is matched to that of the silicone to minimize internal reflection. Tablets can be made virtually identical in composition and size. The bulk of the tablet will be the high TC material. After the tablet is placed in the cup, the LED module is heated, preferably in a vacuum, to melt the silicone so that the mixture flows around the LED die and fills the voids to encapsulate the LED die. The silicone is then cooled to harden.Type: GrantFiled: September 6, 2017Date of Patent: December 11, 2018Assignee: Lumileds LLCInventors: Grigoriy Basin, Mikhail Fouksman

Publication number: 20170301832Abstract: A multi-stage lamination process is used to laminate a wavelength conversion film (220) to a transparent substrate (230), and subsequently to a light emitting element (110). The wavelength conversion film (220) may be an uncured phosphor-embedded silicone polymer, and the lamination process includes heating the polymer so that it adheres to the transparent substrate (230), but is not fully cured. The phosphor-laminated transparent substrate (230) is sliced/diced and the wavelength conversion film (220) of each diced substrate is placed upon each light emitting element (110). The semi-cured wavelength conversion film (220) is then laminated to the light emitting element (110) via heating, consequently curing the phosphor film. Throughout the process, no glue is used, and the optical losses associated with glue material are not introduced.Type: ApplicationFiled: December 30, 2014Publication date: October 19, 2017Inventors: Grigoriy Basin, Paul Martin, Han Ho Choi

Patent number: 9537047Abstract: A method for fabricating an LED/phosphor structure is described where an array of blue light emitting diode (LED) dies are mounted on a submount wafer. A phosphor powder is mixed with an organic polymer binder, such as an acrylate or nitrocellulose. The liquid or paste mixture is then deposited over the LED dies or other substrate as a substantially uniform layer. The organic binder is then removed by being burned away in air, or being subject to an O2 plasma process, or dissolved, leaving a porous layer of phosphor grains sintered together. The porous phosphor layer is impregnated with a sol-gel (e.g., a sol-gel of TEOS or MTMS) or liquid glass (e.g., sodium silicate or potassium silicate), also known as water glass, which saturates the porous structure. The structure is then heated to cure the inorganic glass binder, leaving a robust glass binder that resists yellowing, among other desirable properties.Type: GrantFiled: April 18, 2016Date of Patent: January 3, 2017Assignee: Koninklijke Philips N.V.Inventors: Grigoriy Basin, Stein Kuiper, Paul Scott Martin
