Abstract

Provided is a camera lens assembly including an optical filter employing a plurality of color light emitting diodes. The camera lens assembly includes a lens module having a printed circuit board, an image sensor positioned on the printed circuit board, an IR filter, and a camera lens, the camera lens assembly. The camera lens assembly further includes a base, a lens housing positioned on an upper surface of the base for accommodating the lens module, and formed with a lens aperture at a position corresponding to the camera lens, and an optical filter positioned adjacent to the lens module for selectively transmitting or blocking a color light radiated from a plurality of color light emitting diodes through the lens aperture.

Claims

1. A camera lens assembly for a mobile phone having a camera lens module including a printed circuit board, an image sensor positioned on the printed circuit board, an IR filter, and a camera lens, the camera lens assembly comprising:

a base;

a lens housing positioned on an upper surface of the base for accommodating the lens module, and formed with a lens aperture at a position corresponding to the camera lens; and

an optical filter positioned adjacent to the lens module for selectively transmitting or blocking a color light radiated from a plurality of color light emitting diodes through the lens aperture.

2. The camera lens assembly as claimed in claim 1, wherein the plurality of light emitting diodes are provided at a position on the upper surface of base to radiate color light;

and,

the optical filter includes a diode reflecting plate positioned adjacent the color light emitting diodes to reflect the light radiated from the color emitting diodes onto the lens aperture.

3. The camera lens assembly as claimed in claim 1, wherein the image sensor and the IR filter are provided on an upper surface of the printed circuit board, and a lens mount for retaining the camera lens is installed onto the upper surface of the printed circuit board.

4. The camera lens assembly as claimed in claim 1, wherein the lens housing includes a fixing opening connected to a connection provided at the lens mount.

5. The camera lens assembly as claimed in claim 1, wherein the lens aperture is provided with an optical glass.

6. The camera lens assembly as claimed in claim 2, wherein the lens housing is provided with a space for accommodating the plurality of color light emitting diodes and the diode reflecting plate therein.

7. The camera lens assembly as claimed in claim 2, wherein the plurality of color light emitting diodes are adapted to radiate white, red, magenta, yellow, green and cyan.

8. The camera lens assembly as claimed in claim 7, wherein a yellow-light emitting diode is used as a correction filter in such a way that when yellow light is illuminated onto the optical glass, the diode reproduces bright and dark phases of a subject r, and

wherein a red-light emitting diode is used as a contrast filter in such a way that when a red light is illuminated onto the optical glass, the diode transmits or absorbs a specific wavelength of the light.

9. A camera lens assembly for a camera lens module of a mobile phone, the camera lens assembly comprising:

a base;

a lens housing positioned on an upper surface of the base for accommodating the lens module, and formed with a lens aperture at a position corresponding to the camera lens; and

an optical filter positioned adjacent to the lens module for selectively transmitting or blocking a color light radiated from a plurality of color light emitting diodes through the lens aperture.
