Description

Emotional lighting device and its control method {Apparatus for sensibility lighting and control method

The present invention relates to an emotional lighting device and a control method for setting the lighting conditions according to the environmental lighting, more specifically, the regional environmental factors such as country or city.

European cities such as England, France, Italy, Switzerland, and Germany are all bordered with unknown borders, but their languages are different, and the borders of colors are as clear as those languages. . In other words, European cities, like languages, have their own colors and represent the images of each country. There are red, yellow, green, and blue in any country in Europe, but the difference is lighter, darker, more colorful, or muddy.

The change of natural light according to latitude shifts from short wavelength light to long wavelength light from high latitude to low latitude, and accordingly, color difference occurs, so that all colors are not perceived beautifully in any area, so the nuances of color favored in each area are subtle. Appears different.

There is no people or race that needs, likes, and consumes every color and every tone. Regional differences in color preferences exist.

Korea and Japan are almost at the same latitude and culturally quite similar, but there is a difference in the tendency of color preference. Koreans tend to use many bright and colorful colors, while Japanese people tend to use dark and muddy colors.

The elements that humans need to perceive color are eyes, light sources, and objects. When a human looks at an object's color, the same color may look different due to various influences such as the environment (temperature, humidity, intensity of illumination light) or the optical characteristics of the object itself.

The effect of changes in light sources on perceptual and preferred colors is significant. In this respect, environmental factors affecting regional differences in color sensitivity are natural light intensity, humidity, and temperature. It can be regarded as related.

The illumination data storage unit 30 stores light intensity, color temperature, and wavelength according to the region of the country and city by season and time zone.

2 is a diagram showing the hourly illumination data for each region of the present invention. As shown, a look-up table that records and records light intensity, color temperature, and wavelengths according to seasons and time zones according to the cities of the United States, Korea, etc., and cities of New York, LA, Seoul, Busan, etc., is recorded. The lighting data storage unit 30 is stored.

The illumination data storage unit 30 preferably includes a universal serial bus (USB) memory chip detachable to the apparatus main body, and a conventional reader capable of reading data of the memory chip.

The lighting data storage unit 30 may be installed in a lighting device or installed as a separate place, for example, on a web server (not shown) connected to the Internet, and used as a wired / wireless communication USB memory chip (not shown). You can also download and use).

The season and time detector 40 counts seasons and times, and for this purpose, a conventional timer may be applied.

The controller 20 sets the light intensity, color temperature, and wavelength according to the region of the country and city selected by the region selector 10 according to the current season and time zone counted by the season and time detector 40.

To this end, the control unit 20 includes a light intensity setting unit 21 for setting the light intensity, a color temperature setting unit 22 for setting the color temperature, and a wavelength setting unit 23 for setting the wavelength.

Accordingly, the light intensity setting unit 21 reads out the light intensity data according to the region and city region selected in the region selection unit 10 and the current season and time zone from the illumination data storage unit 30, .

Figure 3 is a diagram showing the color temperature of the present invention, the light is seen as the light scattered in the air, the color of the light is changed according to the temperature is called the color temperature. The unit of this color temperature is kelvin (K) and the higher the temperature, the blueer the light, and the lower the temperature the red light. As shown, the daylight is about 5200K in normal daylight, the candle is 1500-1900, the blue sky is more than 10000K, and the daylight fluorescent lamps we use often have a color temperature of 6000K.

Accordingly, the color temperature setting unit 22 reads color temperature data according to the region of the country and city selected by the region selection unit 10 and the current season and time zone from the illumination data storage unit 30 to set the color temperature.

In addition, the degree of similarity between the object color seen in natural light and the color seen by turning on a lamp is called color rendering, and the closer to 100, the color rendering is good. That is, if the object is the same color as the reference light source and the illumination, Ra (average color rendering index) is 100, and the more the color difference, the lower the Ra value. In the case of incandescent bulbs, Ra is 100 and in the case of fluorescent lamps, there is a difference between products, but Ra is 80 or more.

As described above, the change of natural light according to latitude shifts from short wavelength light to long wavelength light from high latitude to low latitude, and accordingly, color rendering difference occurs. In this embodiment, color rendering of a specific region is realized by adjusting the wavelength of light. Can be.

Accordingly, the wavelength setting unit 23 reads wavelength data according to the region of the country and city selected by the region selection unit 10 and the current season and time zone from the illumination data storage unit 30 to set the wavelength value.

The LED light source driver 50 drives the LED light source 60 including the red LED 61, the green LED 62, and the blue LED 63, respectively, according to the light intensity, color temperature, and wavelength set by the controller 20. Emotional lighting of the optimal state can be implemented according to the season and time of the country and city.
