LED visual approach slope indicator system

The utility model relates to an LED visual approach slope indicator system, which consists of a plurality of LED indicators and a power supply controller; each LED indicator includes a plurality of module units; each module unit consists of a plurality of red LEDs (6), a plurality of white LEDs (7), a plurality of collimating lenses (8), a light combiner (9) and an imaging lens (11); the red LEDs (6) are arranged at the upper parts of the white LEDs (7); each collimating lens (8) is arranged in front of each LED; a reflecting film (14) is arranged at the lower part of the light combiner (9); a layer of red clear filter (12) is arranged in the light emitting direction of the light combiner (9); and a light barrier (13) is arranged between the white LEDs (7) and the lower part of the light combiner (9). The utility model adopts the red and the white LEDs; the light emitting efficiency is high, and the red and the white LEDs are connected in series and driven by the same driver; therefore, the risk can be reduce
