Abstract

Red LED chip(s) 11r, green LED chip(s) 11g, and blue LED chip(s) 11b may be connected in series. In addition, taking Pr to be red intensity, Pg to be green intensity, and Pb to be blue intensity for the same value of electric current, the ratio of the intensities among Pr, Pg, and Pb may be set so as to be 3:7:1, more or less. By integrally mounting such illumination apparatus(es) to portable equipment for illumination when using CCD image pickup element(s) to acquire image(s), improved color reproduction by CCD image pickup element(s) is permitted.

Claims

1. An illumination apparatus characterized in that one or more red light emitting diode chips, one or more green light emitting diode chips, and one or more blue light emitting diode chips are connected in series;

these chips being capable of being driven by one power supply apparatus.

6. A camera apparatus characterized in that one or more illumination apparatuses according to any of claims 1 through 5 are integrally mounted to the apparatus body for illumination when using one or more CCD image pickup elements to acquire one or more images.

7. A camera apparatus according to claim 6 characterized in that at least one gain of at least one of the CCD image pickup element or elements is set based on one or more signals associated with one or more specific wavelengths.

8. A camera apparatus according to claim 7 characterized in that, taking Pr to be red intensity, Pg to be green intensity, and Pb to be blue intensity for the same value of electric current, the ratio of the intensities among Pr, Pg, and Pb is 3:

7;

1, more or less.

9. Portable equipment characterized in that one or more camera apparatuses according to claim 6 are integrally mounted to the equipment body or bodies.

10. Portable equipment characterized in that one or more camera apparatuses according to claim 7 is integrally mounted to the equipment body or bodies

11. Portable equipment characterized in that one or more camera apparatuses according to claim 8 is integrally mounted to the equipment body or bodies.

2. An illumination apparatus characterized in that two red light emitting diode chips, one green light emitting diode chip, and one blue light emitting diode chip are connected in series;

these four chips being capable of being driven by one power supply apparatus.

3. An illumination apparatus characterized in that one or more red light emitting diode chips and one or more chips comprising one or more blue chips and one or more fluorescent substances are connected in series;

these chips being capable of being driven by one power supply apparatus.

4. An illumination apparatus characterized in that one or more blue light emitting diode chips and one or more chips capable of causing excitation so as to produce red and so as to produce green due to combination of one or more violet chips and one or more fluorescent substances are connected in series;

these chips being capable of being driven by one power supply apparatus.

5. An illumination apparatus characterized in that one or more red light emitting diode chips and one or more chips capable of causing excitation so as to produce green and so as to produce blue due to combination of one or more violet chips and one or more fluorescent substances are connected in series;

these chips being capable of being driven by one power supply apparatus.
