Abstract
The utility model discloses a night vision compatible backlight device. The utility model is characterized in that a dual-row LED light bar is disposed at the two opposing sides of an optical guide plate; each dual-row LED light bar is provided with an upper and a lower row of LED lights; night vision films are coated on the surface of the lower row of LED lights; the two sides of optical guide plate are in a stepped appearance. The utility model has advantages of being compatible with night vision function; possessing high backlight efficiency, rich functions and flexible and convenient utilization.
Description
Technical field
The utility model relates to a kind of night viewing compatible back lighting device.
Technical background
The night viewing compatible technology is widely used in the illuminator and display system of aircraft, as military LCD backlight system, the main means that realize night viewing compatible at present are bimodulus backlight technologies, rely on end light to realize highlighted demonstration, realize night viewing compatible in conjunction with sidelight.This kind bimodulus backlight technology exists utilization ratio low, and power consumption is big, the shortcoming that size is big.And, the power consumption of military LCD, size etc. are required more and more higher along with technical development, and when satisfying night viewing compatible, how to improve LED-backlit efficient, reducing power consumption is an important problem.
The utility model content
The utility model proposes a kind of night viewing compatible back lighting device, this night viewing compatible back lighting device compatibility night vision function, and handoff functionality with normal backlight mode and night vision pattern, backlight efficiency height, feature richness, flexible and convenient to use.
Technical solution of the present utility model is as follows:
A kind of night viewing compatible back lighting device respectively is provided with a double LED lamp bar in the relative both sides of LGP, and each double LED lamp bar is provided with two rows LED lamp, is covered with the night vision film on the LED lamp surface of arranging down.
The both sides that are provided with double LED lamp bar of LGP are stairstepping.
Beneficial effect:
The utility model discloses a kind of night viewing compatible back lighting device, there is ladder in the side of LGP, and is corresponding with double LED lamp bar.The row of going up LED light fixture on the LED lamp bar has highlighted characteristics, realizes highlighted backlight; Under arrange LED lamp surface and paste the night vision film, realize night viewing compatible.Since use same LGP and same LED lamp bar, and can comprehensively realize backlight and night vision function, so the utility model design be ingenious, compact conformation, size is little, and the backlight efficiency height has advantage low in energy consumption.
Description of drawings
Fig. 1 is the structural representation (front view) of embodiment 1;
Fig. 2 is the structural representation (vertical view) of embodiment 1.
Label declaration: 1-LGP, the double LED lamp of 2-bar, 3-LED lamp, 4-night vision film.
The specific embodiment
Below with reference to figure and specific implementation process the utility model is described in further details:
Embodiment 1:
As depicted in figs. 1 and 2, a kind of night viewing compatible back lighting device respectively is provided with a double LED lamp bar 2 in the relative both sides of LGP 1, and each double LED lamp bar 2 is provided with two LED lamps 3 up and down, is covered with night vision film 4 on the LED lamp surface of arranging down.The both sides that are provided with double LED lamp bar of LGP 1 are stairstepping.The existence of notch cuttype makes the night vision film can be embedded into the lower end of LGP, thereby shortens the distance of LED lamp 3 with the LGP 1 of the row of going up, and has improved the light utilization ratio of LED lamp.
