Patent number: 7946712Abstract: A projector apparatus equipped with a metal plate structure serving as a light shield against a light source and as a heat radiator is provided. The metal plate structure is arranged over the light source to hide the light source. The metal plate structure extends farther to a cooling fan and connects to the upper end of the air expiration face of the fan. The metal plate structure thus serves as the top plate of the baffle section of the exhaust duct of the fan for leading the air expired from the fan. The metal plate structure also serves as a shield plate, which can be connected to a grounded metal piece.Type: GrantFiled: September 5, 2007Date of Patent: May 24, 2011Assignees: Sanyo Electric Co., Ltd., SANYO Technology Center (Shenzhen) Co., Ltd.Inventors: Xianglin Zhang, Qiang Lv, Shoji Okazaki, Yanshan Huang, Tadashi Renbutsu, Toshihiro Saruwatari, Xiangfei Kong, Wentian Tang

Patent number: 7943898Abstract: A projector apparatus and a lamp fixation structure for use with the projector apparatus are disclosed. The lamp fixation structure has a lower holder, which includes an integrally formed lower holder lens section and a lower holder lamp section. The lower holder lens section defines a lens fitting slot for fixing a lens, and a lower holder lamp section defines a lamp fitting slot for fixing a lamp. The lens fixing slot includes an upper holder connected to the lower holder. The lamp fixation structure also includes an integrally formed metal holder, which has an elastic top plate, elastic lateral plates, a front plate, an elastic bottom plate, and elastic jointing plates. The inventive lamp fixation structure of the projector apparatus consists of a fewer components and can be assembled in a simple manner, yet it is highly wrought.Type: GrantFiled: September 5, 2007Date of Patent: May 17, 2011Assignees: Sanyo Electric Co., Ltd., Sanyo Technology Center (Shenzhen) Co., Ltd.Inventors: Xiangfen Kong, Xianglin Zhang, Shoji Okazaki, Yanshan Huang, Tadashi Renbutsu, Toshihiro Saruwatari, Wentian Tang, Qiang Lv
