In an embodiment, the energizing means 3 comprise:
the road surface vibration piezoelectric power generation device 5 is arranged on the lamp post main body 1 or on the road surface near the lamp post main body 1 and is used for collecting vibration mechanical energy on the road to generate power so as to supply power to the traffic projection lamp system;
the solar power generation device 4 is arranged on the lamp post main body 1 and used for collecting solar energy to generate power and supplying power to the traffic projection lamp system;
the wind-induced vibration piezoelectric power generation device 6 is arranged on the lamp post main body 1 and used for generating power by collecting wind energy and supplying power to the traffic projection lamp system.
The invention adopts three clean energy power generation devices, and the pavement vibration piezoelectric power generation device 5, the solar power generation device 4 and the wind-induced vibration piezoelectric power generation device 6 are pollution-free clean energy power generation modules and provide energy for the whole traffic projection lamp system. The power generation device using the vibration mechanical energy, the wind energy and the solar energy forms a multi-element power supply mode, any one of the three power supply modes can supply power for the traffic projection lamp system, when one of the three power supply modes is damaged, the power supply can not be effectively supplied, and the other two power supply modes are not influenced to continuously supply power for the traffic projection lamp system, so that a flexible power supply system is formed.
In the embodiment, the traffic projection lamp system further comprises an energy storage device 12 capable of storing electric energy, the energy storage device 12 is arranged on the lamp post main body 1, the solar power generation device 4, the wind-induced vibration piezoelectric power generation device 6 and the road surface vibration piezoelectric power generation device 5 are respectively connected with the energy storage device 12 to charge the energy storage device 12, and the energy storage device 12 is connected with the projection lamp 2. The energy storage device 10 is arranged to be charged through the energy supply device 3, the energy storage device 12 supplies power to the projection lamp 2, and when the energy storage device 12 is too large in loss and cannot be used continuously, the energy storage device 12 can be replaced with a new one.
In addition, if the energy supply device 3 directly supplies power to the projection lamp 2, the projection lamp 2 is easily damaged due to the possible unstable power supply of the energy supply device 3; for example, the power supply device 3 may emit too much power to easily overload the projection lamp 2, or the power supply device 3 may emit unstable voltage, which may not only cause the projection lamp 2 to lose too much power, but also cause the projection lamp 2 to be unstable in use. And the energy storage device 12 is charged through the energy supply device 3, and the energy storage device 12 supplies power to the projection lamp 2, so that the risk of damage or loss of the projection lamp 2 caused by the fact that the energy supply device 3 directly supplies power to the projection lamp 2 is reduced.

The energy collection processing circuit 11 includes:
and the rectifying circuit is used for rectifying the current output by the energy supply device 3.
