Publication number: 20240071722Abstract: Embodiments described herein relate to plasma processes. A plasma process includes generating a plasma containing negatively charged oxygen ions. A substrate is exposed to the plasma. The substrate is disposed on a pedestal while being exposed to the plasma. While exposing the substrate to the plasma, a negative direct current (DC) bias voltage is applied to the pedestal to repel the negatively charged oxygen ions from the substrate.Type: ApplicationFiled: November 8, 2023Publication date: February 29, 2024Inventors: Sheng-Liang Pan, Bing-Hung Chen, Chia-Yang Hung, Jyu-Horng Shieh, Shu-Huei Suen, Syun-Ming Jang, Jack Kuo-Ping Kuo

Patent number: 10145526Abstract: A headlamp module comprises a connecting base, a substrate, and at least two edge-type light emitting diode (LED) units. The at least two edge-type LED units are mounted to opposite surfaces of the substrate facing away from each other. Each edge-type LED unit comprises an LED chip, a wavelength converting layer, and a light reflecting layer. The LED chip comprises a bottom surface, a light emitting surface facing away from the bottom surface, and first sidewalls. The wavelength converting layer covers the light emitting surface and the first sidewalls. The wavelength converting layer converts emitted light to a desired range of wavelengths. The light reflecting layer reflects the converted light toward the second sidewalls, thus expanding the angle and brightness of light around the headlamp module and avoiding an unlit or dark area immediately around the headlamp module.Type: GrantFiled: February 15, 2017Date of Patent: December 4, 2018Assignee: HARVATEK CORPORATIONInventors: Zhi-Ting Ye, Shyi-Ming Pan, Chia-Hung Pan

Patent number: 9921359Abstract: A light source module includes a light guide plate, a reflecting film, and a plurality of edge-type light emitting diode (LED) units. Grooves are defined in a lower surface of the light guide plate. The reflecting film is below the lower surface and covers the entire lower surface and the grooves. An air gap is defined between the reflecting film and the lower surface. The edge-type LED units are located in the grooves. Each edge-type LED unit includes an LED chip, a wavelength converting layer, and a light reflecting layer. Light emitted is converted by the wavelength converting layer, reflected towards sidewalls of the wavelength converting layer, and transmitted to the lower surface. The reflecting film reflects light that enters the air gap towards an upper surface of the light guide plate, enabling uniform emission of light from the upper surface.Type: GrantFiled: February 17, 2017Date of Patent: March 20, 2018Assignee: HARVATEK CORPORATIONInventors: Zhi-Ting Ye, Shyi-Ming Pan, Chia-Hung Pan

Patent number: 9799810Abstract: A light emitting device includes a side-emitting assembly, a reflecting cup arranged on a side of the side-emitting assembly, and a package for accommodating the side-emitting assembly and the reflecting cup. The side-emitting assembly with a side surface includes a light emitting chip, a wavelength conversion layer coated on the light emitting chip, and a reflecting layer arranged above the wavelength conversion layer. The reflecting cup has an inner surface facing the side surface of the side-emitting assembly. The inner surface of the reflecting cup is a multifocal paraboloid. The multifocal paraboloid includes multistage paraboloids. The corresponding focal points of the multistage paraboloids are symmetrically distributed on the side surface of the side-emitting assembly.Type: GrantFiled: March 30, 2017Date of Patent: October 24, 2017Assignee: HARVATEK CORPORATIONInventors: Zhi-Ting Ye, Shyi-Ming Pan, Chia-Hung Pan, Ping-Lung Wang

Publication number: 20140307434Abstract: A light source module includes a base, a plurality of light emitting components and a reflecting member. The light emitting components is disposed on the base, and the adjacent light emitting components form a gap therebetween. The reflecting member is disposed on the base and surrounded by the light emitting components. The reflecting member has a reflecting surface facing the light emitting components so as to avoid the light from being blocked by the opposite light emitting component and to redirect the light project via the gap formed between the adjacent light emitting components.Type: ApplicationFiled: April 10, 2014Publication date: October 16, 2014Applicant: WINTEK CORPORATIONInventors: Zhi-Ting Ye, Ming-Chuan Lin, Chia-Hung Pan, Wen-Chieh Wu

Publication number: 20140092628Abstract: An illumination device including a light guiding element, a light emitting element, and a reflective element is provided. The light guiding element has a light incident surface, a light emitting surface, a first surface and a second surface. The light incident surface surrounds the light guiding element and is connected between the light emitting surface and the first surface. The first surface is connected between the light incident surface and the second surface so that the second surface is substantially opposite to the light incident surface. The second surface constructs a depression structure having a diameter gradually changed from the first surface towards the light emitting surface. The light emitting element surrounds the light guiding element to emit a light towards the light incident surface. The reflective element is disposed at least on the first surface.Type: ApplicationFiled: October 2, 2013Publication date: April 3, 2014Applicant: WINTEK CORPORATIONInventors: Zhi-Ting Ye, Chia-Hung Pan, Ming-Chuan Lin, Hung-Pin Chang, Wen-Chieh Wu
