Abstract

The invention discloses a two-color light emitting body alarm lamp, wherein a red light emitting body and a green light emitting body are adjacently arranged and are respectively controlled; when two paths are respectively electrified, red or green displays; when the two paths are electrified at the same time, because the red light emitting body and the green light emitting body are close, yellow displays in the vision of human. Therefore, according to the two-color light emitting body alarm lamp disclosed by the invention, a function that two paths of signals control a red, yellow and green three-color signal lamp is realized.

Description

technical field [0001] The invention relates to the technical field of warning light electronic circuits, in particular to a two-color luminous body warning light. Background technique [0002] Common alarm lights are usually composed of three colors of red, yellow and green, and are generally composed of light-emitting elements of three colors, such as light-emitting diodes. purpose of color. However, in the prior art, three color light-emitting elements and three control loops are used, and there are many elements and complicated circuits, resulting in high cost. Contents of the invention [0003] In order to solve the technical problems in the background technology, the present invention proposes a two-color illuminant warning light, which reduces the number of illuminants, reduces the complexity of the control loop, and further reduces the cost. [0004] A kind of two-color luminous body alarm lamp proposed by the present invention comprises: [0005] Adjacent red i...
