Patent number: 9115872Abstract: A lighting device includes a base, a light source, an optical color wheel, and a lens. The base has a plurality of fins for heat dissipation. The light source is disposed in the base, and the optical color wheel is disposed above the light source and in contact with the base. The lens is movably disposed on the base. The Light from the light source passes through the optical color wheel to form colored light. The colored light passes through the lens to form a light beam. Heat generated by the light source and the optical color wheel is dissipated by the fins.Type: GrantFiled: September 20, 2011Date of Patent: August 25, 2015Assignees: LITE-ON ELECTRONICS (GUANGZHOU) LIMITED, LITE-ON TECHNOLOGY CORPORATIONInventors: Shun-Chung Cheng, Chih-Huang Wang, Chang-Ming Cheng

Patent number: 8256930Abstract: A light-emitting diode module includes a transparent base, a support and a plurality of light-emitting chips. The base has a plurality of cavities separated from each other by a predetermined distance in order to respectively receive the light-emitting chips to form light-exiting areas. The base has a reflecting portion opposite to the cavities. The reflecting portion is at least one inclined plane for reflecting light that have projected outside walls of the cavities to the peripheral area of the light-emitting areas in order to increase the uniformity of the light source. In addition, the light-emitting chips are arranged to form a line or surface light source of any sizes by adjusting the numbers of the cavity and the light-emitting chips.Type: GrantFiled: January 19, 2010Date of Patent: September 4, 2012Assignees: Silitek Electronic (Guangzhou) Co., Ltd., Lite-On Technology CorporationInventors: Shun-Chung Cheng, Hsiu-Tsu Wang, Chih-Lung Liang, Chia-Hao Wu

Publication number: 20120194068Abstract: A lamp includes a housing, a plate body disposed in the housing and having a wavelength-conversion material, a light-emitting module disposed in the housing and spaced apart from the plate body, and a light sensor disposed on the plate body. The light-emitting module includes a circuit board, and a plurality of light-emitting units disposed on the circuit board and emitting light onto the plate body. The light sensor is used for sensing the color temperature of light that is emitted from the light-emitting units and that propagates within the plate body.Type: ApplicationFiled: August 9, 2011Publication date: August 2, 2012Applicants: LITE-ON TECHNOLOGY CORP., SILITEK ELECTRONIC (GUANGZHOU) CO., LTD.Inventors: SHUN-CHUNG CHENG, CHIH-HUANG WANG, CHANG-MING CHENG

Patent number: 8222801Abstract: A lamp includes a lamp holder module and light-emitting module disposed in the lamp holder module. The lamp holder module includes a body, a pressing mechanism disposed on the body, and an upper cover engaging removably the body. The light-emitting module is placed on the body and is pressed into position through the pressing mechanism. The pressing mechanism is operable to release the light-emitting module, thereby facilitating removal and installation of the light-emitting module. The upper cover serves as a lens of the light-emitting module and covers the light-emitting module.Type: GrantFiled: June 23, 2010Date of Patent: July 17, 2012Assignees: Silitek Electronic (Guangzhou) Co., Ltd., Lite-On Technology Corp.Inventors: Yan-Yu Wang, Chen-Yu Chen, Chih-Lung Liang, Shun-Chung Cheng

Patent number: 8097899Abstract: A light emitting diode of the present invention comprises a support frame, a shell, a light emitting diode chip and an encapsulating body. The shell is used to accommodate the support frame. The shell has a bowl-shaped structure and the bowl-shaped structure has two opposite first walls and two opposite second walls. The upper edge of the second wall is a concave-convex structure. The encapsulating body is used to package the bowl-shaped structure and the encapsulating body has a concave-convex structure similar to the concave-convex structure of the bowl-shaped structure. The concave-convex structure comprises a concave portion and a convex portion. The structure of the light emitting diode is simplified. The luminous intensity and the light extraction efficiency of the light emitting diode are enhanced and the thickness of the light emitting diode is not increased.Type: GrantFiled: September 25, 2009Date of Patent: January 17, 2012Assignees: Silitek Electronic (Guangzhou) Co., Ltd., Lite-On Technology CorporationInventors: Chia-Hao Wu, Shun-Chung Cheng
