| Abstract: |
A color identifying device includes an emitter for supplying light to throw on a tested object, an amorphous photosensor, an amplifier, an ADC and a microprocessor. The emitter is formed with a LED producing three original colors or with three separate LED producing separate colors of red, green and blue. The photosensor receives the reflected light from the object and sends signals of three colors to the amplifier which amplifies the signals and sends them to the ADC. Then the ADC converts the analog signals into digital signals to be sent to the microprocessor which calculates the digital signals by a program identifying the colors of the object accurately. |

| Claim: |
What is claimed is |
| Claim: |
1. A color identifying device comprising an emitter, an amorphous photosensor, an amplifier, an ADC (analog digital converter), and a microprocessor; |
| Claim: |
said emitter supplying light on a tested object; |
| Claim: |
said amorphous photosensor receiving the reflecting light from the object and providing signals of red, green and blue color contained in the reflected light to said amplifier; |
| Claim: |
said amplifier amplifying the signals of the reflected light and providing output signals to said ADC; |
| Claim: |
said ADC receiving the analog signals coming from said amplifier and converting the analog signals into digital signals and providing said digital signals to said microprocessor; |
| Claim: |
said microprocessor performing calculation of the digital signals coming from said ADC by a program and identifying colors of said object; |
| Claim: |
characterized in that said emitter including a single combined LED producing light of three original colors, red, green and blue, a housing provided to contain said emitter, a concave lens provided in said housing for dispersing and mixing the three original colors produced by said LED of said emitter, so as to supply a visible light very similar to sunlight to be provided on said tested object. |
| Claim: |
2. The color identifying device as claimed in claim 1, wherein said emitter is formed with three separate LEDs of red, green and blue colors, said housing is provided to contain said emitter, and a concave lens is provided in said housing for dispersing and mixing the light of the three colors produced by said emitter for acquiring a visible light very similar to sunlight. |
