Title: Apparatus and method of correcting output of led array
Inventor: KAGAWA TETSUYA
IPC: B41J2/455
Filed: 1992-11-11
Abstract: PURPOSE:To restrict the influences of the irregularity of the outputting characteristic of light of LED elements in an inexpensive constitution by providing means for correcting the luminous intensity of the entire group of the LED elements to be a specific value, and means for supplying correction data obtained through the correction to a current impressing means. CONSTITUTION:The output data from an image processing part 21 is fed to a gradation correcting part 22. The gradation correcting part 22 corrects the gradation of image data corresponding to the light emitting characteristic of individual LED elements constituting an LED array head 11. The correction data corrected in gradation at the gradation correcting part 22 is fed to a head controller 23 as a current impressing means. The head controller 23 feeds a current corresponding to the correction data to the individual LED elements of the LED array head 11. Accordingly, even when the characteristic of the LED elements constituting the LED array head 11 is irregular, the gradation is correctly expressed corresponding to the image data.

Filed: 1997-11-04
Abstract: PROBLEM TO BE SOLVED: To provide a thin and high output fluorescent lamp by adopting a fluorescent discharge tube having two concentrically circular discharge paths on the same plane, and by setting diameters of two discharge tubes forming these two discharge paths within the specific range. SOLUTION: Two ring-shaped discharge tubes 10 and 20 are installed concentrically on the same plane. Discharge spaces of the discharge tubes 10 and 20 are connected with a bridge 1. The electrode 11, the discharge tube 10, the bridge 1, the discharge tube 20 and the electrode 21 are connected through a discharge path in that order. To arrange the two concentrically circular discharge tube within the same flat plane, these discharge tube should be processed with high precision to form truly circular ring shapes. If the tube diameter of the discharge tube is more than 25mm, the processing of truly circular ring-shaped glass encounters difficulties, and if the tube diameter thereof is less than 10mm, the glass mechanical intensity is decreased. Therefore, the optimum tube diameter of the discharge tube ranges between 10mm and 25mm.
