A method for adjusting output ratio of an optic sensor includes the following steps: measuring and obtaining a response spectrum of the optic sensor; analyzing optic response ratios of the response spectrum at different wavelengths; designing a ratio of light reception areas of the optic sensor, the design being carried out in accordance with three aspects of 'the response spectrum' 'a fixed proportional relationship being present between multiplication of the optic response ratio and the light reception area and an output of light current' and &#x201c;a proportional relationship being present between the light reception area and the output of the light current&#x201d;; and obtaining light current outputs of identical proportions (such as 1:1:1) or in a desired ratio (meaning any arbitrary ratio other than 1:1:1, such as 1:2:1, 1:2:3, or 3:4:5) in accordance with the design of the previous step.

Output ratio adjusting method for optic sensor

A LED-based light emitting device having integrated rectifier circuit driven directly by an AC voltage and a related fabrication method is provided herein. The light emitting mainly contains a lower substrate and an upper substrate. The lower substrate has a built-in rectifier circuit and appropriate electrical contacts of the rectifier circuit are exposed on the top surface of the lower substrate. The upper substrate contains multiple LEDs arranged in an N&#xd7;M array and the LEDs are all electrically insulated from each other. Metallic plating techniques are applied to establish electrical connection between these LEDs so that they jointly form a circuit matching the rectifier circuit on the lower substrate. The two substrates are faced towards each other and metallic bumps are applied to connect the LED circuit on the upper substrate to the rectifier circuit on the lower substrate, completing a fully function light emitting device.
