Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a lighting device using a light-

The present invention relates to a lighting device using a lighting module for a color vision aberration, and more particularly, to a lighting device for a color vision aberration which provides a lighting for a user who can not accurately perceive a color to be in color more than a color perception, And more particularly to a lighting apparatus using the same.

In the human eye, there is a retina for discriminating an image. The retina has a visual cell that discriminates an image by stimulation when the image is formed, and the visual cell transmits the stimulated signal information to the brain so that the visual image is recognized.

Conical cells and rod cells are present in the cytoskeleton. The cone cells are composed of cone cells of RGB (RED GREEN BLUE) which distinguishes colors. When red is inputted into the retina, R-cones are stimulated When green is entered, the G-cone cell is stimulated to feel green. When blue is input, the B-cone cell is stimulated and the blue color is felt.

The light or color is synthesized by combining the three colors of red, green, and blue (R, G, and B) to represent all colors, and the colors are distinguished by the ratio of the R, G, and B cones.

When the retina is normal, it recognizes all the natural colors. However, when the retina has a disorder such as a color vision abnormality, the natural color is not recognized properly.

There are color blindness that does not recognize a specific color largely, and color pencil which lacks recognition ability of a specific color.

The color blindness patient is caused by the absence of any one or more conical cells among the R, G, and B conical cells, and the coloring matter is caused by the fact that one or more kinds of conical cells are deficient or poor in ratio than normal ones, If the color is mixed with another color, it can not distinguish the color.

According to the type of the cone cell whose function is weakened, it is divided into red medicine, green medicine and blue medicine. In fact, almost all color medicine patients are red medicine and green medicine, and blue medicine is very rare.

That is, the red medicine is a function of the R-cone cell receptor which senses red (R) slightly. For example, in a picture or image mixed with red (R) and green (G) In contrast, the green medicine shows only the red part because the G-cone cell function, which is a receptor for sensing the green, is slightly lowered.

However, the above-mentioned red medicine, green medicine, and the like are weak in the function of the cone cell that senses red or green, but can distinguish when there is only one color of red or green. For example, When a mixture of red and green is mixed, a person with a red color distinguishes the mixture of red and green by applying a thicker red color, while a person with a green color distinguishes a mixture of red and green by applying a darker green color.

More specifically, a person having a normal retinal structure recognizes white light with a ratio of 1: 1: 1 as an example, while a person with a red color has a red-green ratio of 2: 1: 1 White light is recognized as white, and in the case of a red medicine having a severe degree, 3: 1: 1 light is recognized as white, and even when the red medicine is the red medicine, only red light is recognized.

In the case of a red medicine, for example, it is common to calibrate the red color so as to increase the contrast of the two colors because a large amount of red is transmitted and a large amount of green is blocked Korean Patent Registration No. 10-0304799 entitled " Optical means and method for correcting or improving the color angle and method for manufacturing the optical means "), optical means for correcting or improving the color tone are disclosed. .

However, glasses and contact lenses using such conventional optical means are configured to be used in outdoor environmental conditions, and are darkened due to lack of light due to filtering glasses.
