The front combination lamp comprises a daytime running lamp, a front position lamp and a front steering lamp, the front combination lamp is a yellow light and white light double-color LED and shares an optical system, the circuit control system has priority logic judgment of the daytime running lamp, the front position lamp and the front steering lamp, the priority of the front steering lamp is achieved, the priority of the second front position lamp and the daytime running lamp is achieved, and the priority of the second front position lamp and the second front steering lamp is achieved. When the front steering lamp works, the daytime running lamp or the front position lamp is automatically cut off, and when the front position lamp works, the daytime running lamp is automatically cut off. And meanwhile, voltages in three different states of a daytime running lamp, a front position lamp and a front steering lamp are output to the single chip microcomputer.
昼行灯、前位置灯和前转向灯的前组合灯和电路控制系统,其中前组合灯为黄光和白光双色LED,并共用光学系统,电路控制系统具有昼行灯、前位置灯和前转向灯优先逻辑判定,实现前转向灯最优先级,其次前位置灯,昼行灯最低级,实现前转向灯工作时,自动切断昼行灯或前位置灯,前位置灯工作时自动切断昼行灯;同时输出昼行灯、前位置灯和前转向灯三种不同状态的电压给单片机信号。
