The invention provides a signal lamp flicker control circuit and a signal lamp device, the signal lamp flicker control circuit is used for providing a power supply signal for a first signal lamp, in the signal lamp flicker control circuit, a first controller can control the first signal lamp to flicker through controlling an armature of a first relay, and the first relay is connected with the first controller. And the middle contact and the front contact of the first relay are communicated, so that the power supply signal of the input end is applied to the first switch. The first switch can respond to the power supply signal and intermittently output the power supply signal to the output end through repeated on-off operation so as to control the first signal lamp to flicker through the intermittently output power supply signal. The cost, the failure rate and the maintenance difficulty are reduced, and the service life is prolonged.
本申请提供一种信号灯闪烁控制电路和信号灯设备,该信号灯闪烁控制电路用于向第一信号灯提供供电信号,在信号灯闪烁控制电路中,第一控制器可在控制第一信号灯闪烁的情况下,通过控制第一继电器的衔铁,将第一继电器的中接点与前接点连通,以使输入端的供电信号施加在第一开关上。第一开关可响应于供电信号,通过重复进行的通断操作,间断性的将供电信号输出至输出端,以通过间断性输出的供电信号控制第一信号灯闪烁。本申请降低了成本、故障率和维修难度,提高了寿命。
