The application of solar sensor street lamp in reality

The energy problem is a worldwide problem. Now the resources used by the earth are gradually lacking in the continuous development and utilization of people, and the growing population increases the demand for energy. However, in this process, we should coordinate the relationship between resource utilization and environmental protection. Solar energy as a skill of environmental protection and "inexhaustible" new energy has been applied in practice. According to the situation and actual use of our country, the technology of solar street lamp is getting better and better. Under the condition of increasing the gross National product, we should continuously improve people's production and living conditions. In solar energy products, solar photovoltaic power generation, solar lamps and lanterns have been developed, and these solar products are the most widely used in rural China, solving the rural night lighting and some basic electricity problems. The use of solar street lights saves the cost of installing municipal power lines.

In China, because solar street lamps are widely used in rural areas, the production and selection of various accessories of solar street lamps should be consistent with the local environmental conditions. Only in this way can solar street lamps give full play to their maximum effectiveness. Environmental factors are an important condition. Now most solar street lamps use controllers to adjust the lighting time and power of solar street lamps. However, the environmental weather cannot be controlled. Another example is the late dawn of a winter morning, when the solar street lights go out at a preset time. So there's something about this system that's not flexible enough, that's not smart enough. So according to the brightness of the sky to control the solar street lamp, can also be controlled by human body induction. This can make the use of solar street lamps much closer to the actual environment, more scientific, more intelligent.

And solar street lights generally use infrared induction module +PMW control to do. For the heating stage sensitive energy, can detect the thermal radiation of the human body, simply like the sound and light controller in the corridor, is a principle, plus polar dimming, intelligent street lamp, there is a single chip control, by adjusting by adjusting the duty ratio, that is, PWM to control the brightness, lamp beads use environmental protection LED lamp beads. However, it should only be applied to the area where people walk. It should not be applied to the road. The speed is too fast and the system perception distance is limited.

If it is to be used in driving, multiple PIR sensors and LDR sensors can be used together for fast vehicles. But for now, I'm going to focus on human sensors rather than sensors used in vehicles.

For solar sensor street lamp, the induction distance of the sensor can be selected according to the installation interval of solar street lamp. Even if the distance is far away, the sensor can be sensitive, which can meet the most humane requirements.

The humanized device is safe and convenient

1.full waterproof design: using the upper plate buckle plate design, built-in waterproof sealing rubber ring

2.Convenient installation: 2-3 meters high is recommended, and the lighting range measured at night is 20 square meters

3.humanized design: the pinhole type waterproof switch, once activated intelligent permanent (pinhole switch, marked with the small hole.OFF, in the dark environment, with the activation needle prick the small hole, a moment will be bright)

4.infrared human body sensor: the sensor lamp, the distance is made according to the requirements.

Work flow of solar body induction lamp:

1.During the day, there is sunlight for charging. The ideal state is 8-10 hours of charging

2.At night, the lamp will automatically start the light mode

3.When someone passes by, the infrared sensor will be triggered, and the light will automatically turn on the strong bright mode. The strong light will last for 30 seconds

4.when people leave the induction range, the light will automatically turn into a slightly bright mode

As a renewable energy, solar energy is safe, environmentally friendly and inexhaustible. At present, many places in life have already adopted the effect of solar energy, such as: solar water heater, solar charging treasure...... The full listing of solar sensor street lamp not only brings great convenience to people's lives, but also greatly saves energy development.
