Publication number: 20220293813Abstract: An optoelectronic module, including a substrate, a covering member, a light emitting element, and a light receiving element, is provided. The covering member is disposed on the substrate and includes an upper cover portion, a peripheral sidewall portion connected to the upper cover portion, and an inside partition delimiting a first cavity and a second cavity. The first cavity is separated from the second cavity. The light emitting element is disposed on the substrate as corresponding to the first cavity. The light receiving element is disposed on the substrate as corresponding to the second cavity. The inside partition has a first inner wall surface located in the first cavity and a second inner wall surface located in the second cavity. A first protruded-recessed structure is formed on the first inner wall surface.Type: ApplicationFiled: March 10, 2022Publication date: September 15, 2022Applicant: Lite-On Technology CorporationInventors: Jui Lin Tsai, Chien Tien Wang, Shu-Hua Yang, Hsin Wei Tsai, You-Chen Yu

Patent number: 8421329Abstract: A luminaire includes a lamp holder, a lamp cover and a plurality of first light-emitting modules. The lamp holder has a top surface, a plurality of protrusions protruding upwardly from the top surface. Each of the protrusions has an inclined surface. The lap cover is connected to the lamp holder, and covers the top surface and the inclined surfaces. Each of the first light-emitting modules includes a first light-emitting element. The view angle of the luminaire can be increased due to disposition of the first light-emitting elements on the inclined surfaces of the protrusions. Furthermore, since the first light-emitting elements are disposed on the protrusions, heat can be dissipated easily from the first light-emitting elements.Type: GrantFiled: June 13, 2011Date of Patent: April 16, 2013Assignees: Silitek Electronic (Guangzhou) Co., Ltd., Lite-On Technology Corp.Inventors: Chih-Lung Liang, Shu-Hua Yang, Chin-Ming Cheng, Jui-Lin Tsai

Patent number: 8282249Abstract: A luminaire comprises a lamp holder, a lamp cover, a light-emitting module, and a light guide element. The lamp cover is assembled to the lamp holder to define an accommodating space therebetween. The lamp holder has a platform part protruding into the accommodating space. The light-emitting module is mounted to the platform part, and includes a circuit board and at least one LED disposed on the circuit board. The light guide element is mounted to the platform part, and covers the light-emitting module. The light guide element has an outer diameter longer than that of the platform part. The light guide element is shaped to allow light emitted from the LED to be transmitted out of the lamp cover through the light guide element in a lateral direction, and thus the view angle of the luminaire is increased.Type: GrantFiled: April 14, 2011Date of Patent: October 9, 2012Assignees: Siltek Electronic (Guangzhou) Co., Ltd., Lite-On Technology Corp.Inventors: Chih-Lung Liang, Jui-Lin Tsai
