Self-learning LED (Light-Emitting Diode) navigation aiding lamplight strength control device

Abstract

The invention relates to a self-learning LED (Light-Emitting Diode) navigation aiding lamplight strength control device. The input ends of a transformer and a current transformer are connected to the secondary stage of an isolation transformer in a navigation aiding lamp loop after being connected in series; the output end of the transformer is connected with the input end of a power supply unit; the output end of the power supply unit is connected with the power supply input ends of a control unit and a driving unit; the output end of the current transformer is connected with the input end of the detection unit; the output end of the detection unit is connected with the input end of the control unit; the output end of the control unit is connected with the input end of the driving unit; and the output end of the driving unit is connected with an LED light source. The self-learning LED navigation aiding lamplight strength control device has the advantages that: the LED navigation aiding lamp can be used for directly replacing the original conventional navigation aiding lamp for an airport, so that an original dimming system is not required to be refitted; in a designed lamp, a high-power LED is taken as a light source; and compared with the conventional lamp, the self-learning LED navigation aiding lamplight strength control device has the characteristics of pure light color, low power consumption, long service life, high adaptability, and the like.

Description

technical field [0001] The invention relates to airport navigation lighting equipment, in particular to a self-learning LED navigation lighting intensity control device. Background technique [0002] At present, the navigation aid dimming system widely used in civil aviation airports, the light intensity of the light is divided into 5 levels. Adjust the light intensity of the airport navigation lights to the required light intensity level through the constant current dimmer. The secondary of the step-up transformer T1 is connected to the navigation light circuit. The navigation light circuit is a suspension circuit connected in series by a series of isolation transformers T2, such as figure 1 shown. The current flowing through all the isolation transformers T2 in this circuit is the same, the navigation light L is connected to the secondary of the isolation transformer T2, the primary and secondary currents of the isolation transformer T2 maintain a 1:1 relationship, and ...

AI Technical Summary

Problems solved by technology

[0005] At present, most of the light sources for navigation aids at airports are incandescent lamps and halogen tungsten lamps, which have high power and low efficiency.

Short life and other shortcomings, and when in use, need to use color filters to get the required color light, not only the utilization rate is low, but also the light color is not pure

When using LED as the light source, it cannot be directly connected to the dimming circuit, and an additional drive control circuit device is required
