Problems solved by technology

In this method, when the slope indicator is working, since there are three motors working at the same time, the design of the circuit drive is difficult, the motor emits a lot of noise, and generates a lot of energy consumption. At the same time, the mechanical size of the equipment is increased.

Embodiment Construction

[0061] The invention provides a novel three-color visual approach gradient indicator, which is driven by a motor to rotate a turntable containing three groove tracks, and the three grooves drive three light-blocking plates containing a cam structure to the object surface of the imaging objective lens. The filter on the screen performs a blocking motion to achieve flash.

[0062] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in further detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0063] In an exemplary embodiment of the present invention, a three-color visual grade indicator is provided, see figure 2 , the three-color visual gradient indicator includes: a heat dissipation module 100, an LED light source 200, a lens group and a flashing mechanism.

[0064] The LED light source 200 is fixed on the heat dissipation module 100 . T...

Abstract

The invention provides a three-color visual approach slope indicator. According to the three-color visual approach slope indicator, three-way flash structures are driven by a single motor, therefore, the design and test difficulty of a motor driving circuit is reduced, the occupied space of the motor is decreased, and the noise produced by the motor is lowered; in addition, three track grooves are formed in a rotating plate for supplying power to a light filter and light shields, and the light shields do not impact on one another; various numbers and types of light shields can be selected according to the flash requirement of users, monochrome flashing, bicolor flashing, full shielding, half shielding and other modes are provided, and the high practical value is achieved.

Description

technical field [0001] The invention relates to the technical field of aviation equipment, in particular to a three-color visual approach slope indicator used to guide pilots to correctly adjust the flight slope when approaching the track. Background technique [0002] The three-color visual approach slope indicator is a light indicating device used to guide the pilot to correctly adjust the flight slope when approaching the track. Such as figure 1 As shown, the three-color visual approach slope indicator used at the airport can provide pilots with three slope signals: yellow-above the approach course, green-on the approach course, red-below the approach course. The beam angle in the vertical direction is 14°, of which yellow light is 8°, green light is 2°, red light is 4°, and the horizontal angle is 32°. The flash mechanism requires three types of flashes: yellow flash, red flash and side flash, and the frequencies of the three flashes are different. The yellow flash fr...
