Abstract

The invention discloses a breathing-type warning lamp for construction at night, which is characterized by comprising a 220V alternating-current power supply, a full-bridge rectification and load circuit and a one-way silicon controlled rectifier triggering and breathing circuit. To maintain the road traffic safety, a red caution lamp is usually hung beside a pit dug in a road to remind pedestrians or vehicles coming and going at night to avoid the risk of falling into the pit. The common red caution lamp mainly emits unchanged red light, and the actual warning effect is poor. Therefore, the breathing-type warning lamp for construction at night has a flickering function in operation at night, has a far better warning effect than that of the emitted unchanged red light, and emits noticeable flickering light at night, thereby achieving a purpose that the construction field is unattended at night. The breathing-type warning lamp for construction at night has the characteristics of simple circuit, good effect, reliable operating performance and the like.

Description

technical field [0001] The invention belongs to the application field of electronic technology, and relates to a nighttime construction breathing reminder lamp. Background technique [0002] In the construction of municipal projects such as laying roads, laying water supply and drainage pipelines, gas liquefied gas or natural gas pipelines, underground power lighting cables, communication cables and optical cables, in order to maintain road traffic safety, red warning lights are usually hung beside the trenches excavated on the road , to remind pedestrians or vehicles coming and going at night to avoid falling into dangerous ditch pits. Most of the commonly used red warning lights emit a constant red light, and the actual warning effect is not good. Accordingly, the night-time construction breathing reminder lamp of the present invention has a flashing function when it works at night, which has a better warning effect than the constant red light, and emits eye-catching flas...
