Patent number: 12259660Abstract: An inspection method and an inspection platform applicable for inspecting a light source used to expose a substrate. The light source is adapted to form an illuminated area on a surface of the substrate. The inspection method includes the following steps: placing at least one inspection component on the surface of the substrate; causing the at least one inspection component and the illuminated area to have a relative movement and a relative speed in a specific direction so as to make the illuminated area move across the at least one inspection component, wherein in the specific direction, the illuminated area is smaller in size than the at least one inspection component; inspecting photon energy of incident light in the illuminated area by the at least one inspection component during the relative movement; and determining optical values of the light source according to the photon energy and the relative speed.Type: GrantFiled: February 21, 2022Date of Patent: March 25, 2025Assignee: INDUSTRIAL TECHNOLOGY RESEARCH INSTITUTEInventors: Cheng-Hsien Chen, Shu-Chun Liao, Shau-Wei Hsu, Wei-En Fu, Tsung-Ying Chung, Yi-Chen Chuang

Patent number: 9253836Abstract: A light-emitting device includes a power module, a first light-emitting module, a second light-emitting module, a third light-emitting module, and a control module. The power module is configured to rectify an AC voltage for providing a periodic driving voltage. The first, second, third light-emitting modules are connected in series. The control module is configured to make the first, second, third light-emitting modules being driven by the driving voltage in response to different driving stages in a cycle period of a driving voltage. An average-diode-junction-area of the first light-emitting module is different from an average-diode-junction-area of the second light-emitting module or an average-diode-junction-area of the third light-emitting module.Type: GrantFiled: August 26, 2013Date of Patent: February 2, 2016Assignee: LEXTAR ELECTRONICS CORPORATIONInventors: Cheng-Chun Liao, Chia-Yen Lee
