Patent number: 7659549Abstract: The present invention is a method for obtaining a better color rendering with a photoluminescence plate, and the better color rendering is obtained by using UV radiating on the photoluminescence plate stacked with a red photoluminescence plate, a green photoluminescence plate and a blue photoluminescence plate. Therefore, the color rendering is above 90% and close to the solar light. The photoluminescence plate can be made from directly coated with photoluminescence layers of three colors or with fully mixed fluorescent materials of three colors. Consequently, a white light relied on the present invention is more uniform than the conventional techniques with a color mixing performance based on tricolor LEDs.Type: GrantFiled: October 23, 2006Date of Patent: February 9, 2010Assignee: Chang Gung UniversityInventors: Ray-Ming Lin, Jen-Chih Li, Yung-Hsiang Lin, Yuan-Chieh Lu, Yi-Lun Chou

Patent number: 6699379Abstract: An improved plating method in combination with a low-temperature thermal treatment is disclosed. The method for reducing the stress in the nickel-based alloy plating comprises the steps of: (a) adding ceramic particles into a plating bath containing soluble nickel salts; and (b) placing a substrate in the plating bath and thereafter carrying out a pulse-current electroplating in the plating bath. The method of this invention can prevent substrate softening or deformation problems. The use of a post low-temperature thermal treatment can slightly increase the hardness of the coating products. The use of the low-temperature thermal treatment can reduce the stress of the coatings since the hydrogen embrittlement resulting from exist of hydrogen in the coatings is eliminated.Type: GrantFiled: November 25, 2002Date of Patent: March 2, 2004Assignee: Industrial Technology Research InstituteInventors: Shih-Tsung Ke, Jen-Chih Li, Ming-Der Ger, Le-Min Wang, Yeh Sung, Jauh-Jung Yang, Ya-Ru Huang
