Detailed Description
The invention will be described in further detail below with reference to specific embodiments and drawings. Here, the description of the embodiments is provided to help understanding of the present invention, but the present invention is not limited thereto. In addition, the technical features involved in the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
The typical wavelengths of the red LED, the green LED and the blue LED selected by the night vision compatible full-color illumination light guide plate are 620nm, 525nm and 470nm, and the corresponding color coordinates are respectively (refer to a wavelength-color coordinate comparison table): r (0.683, 0.317), G (0.166, 0.792), B (0.115, 0.109); the color coordinates of the target white light W are set to (0.316 ), and the brightness contrast of the red LED, the green LED, and the blue LED with wavelengths of 620nm, 525nm, and 470nm is about 2.96:6.5:1 according to the preliminary calculation result.
The ratio obtained by the calculation is based on the self light mixing of the LED light source, the calculated value is only suitable for light source testing, color deviation caused by the attribute of a paint layer exists in the actual backlight illumination of the night vision light guide plate, and the color ratio needs to be adjusted again for the color coordinate of the target color so as to realize the white color.
Referring to fig. 1, according to the existing LED usage conditions, an EVERLIGHT three-primary-color LED is selected, and the model is: 15-13D-R6 GHBHC-A01-2T. The proportion is calculated theoretically by using the model of the three-primary-color LED. And adjusting a potentiometer, controlling R, G, B current proportion of the three-color light source, and testing to make the chromaticity meet the target requirement. The final current ratio is about 20: 17: 1. on the basis, a night vision full-color filter cover (as shown in figure 3) is added on the RGB full-color LED, and the glass powder can effectively absorb red light and infrared spectrum with the wavelength of more than 650nm, so that the requirements related to compatibility with a Night Vision Imaging System (NVIS) in GJB1394-1992 aircraft interior lighting compatible with the night vision imaging system are met. Through the filtering of the night vision full-color filtering cover, the illumination module which meets the requirements of GJB1394-1992 relating to aircraft interior illumination compatible with a night vision imaging system and is compatible with the Night Vision Imaging System (NVIS) is finally obtained.
Referring to fig. 2, for the two-color mode, resistors with different resistances are added to the three primary color circuits respectively based on the single-color mode. Taking a night vision green A and blue-white light double-color mode light guide plate as an example, the night vision green A meeting the requirements of brightness, chromaticity and auxiliary brightness is obtained by adjusting a knob of a potentiometer. On the basis, resistors with different resistance values are added in red, green and blue light paths, so that the brightness of different colors is changed, and finally the required blue-white light is obtained. Use full-color LED to match the full-color and strain the look cover, need not use two kinds of different LEDs and strain the look cover, in the most limited space, reach better even effect. Therefore, for the light guide plate which is difficult to reach or even cannot meet the technological requirements in the previous design process, the design and dimming difficulties can be reduced, and the labor cost and the time cost are saved.
The foregoing merely represents embodiments of the invention, which are described in some detail and detail, and therefore should not be construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
