How to Choose Sensor for Integrated Solar Street Light?
Integrated solar street light is an environmentally friendly lighting product. In order to power the street light, solar energy is used. Traditional street lighting will remain on all night, polluting the night sky and obstructing nighttime drivers' view. One of the serious environmental issues is light pollution. With the advancement of solar street light technology, manufacturers create innovative solutions to the lighting system's power requirements and the issue of light pollution. The use of motion sensors and timers can significantly reduce the amount of power used. Motion sensors used to assist street lights save electricity include PIR and radar sensors. Let's get to know them and choose which is best for you.
1. Time control
The CPU is utilized to regulate the power over time. Dual time periods, three time periods, and multiple time periods are the most common types. As an illustration, consider the 3-period control mode. After the light control is turned on, it will operate at 100% power for the first hour, 75% power for the next, and 50% power for the third hour before shutting out entirely. This control mode's feature is lessening some unnecessary lights while extending the life of the lamp battery. However, this lacks intelligence. In the third hour, the lighting is only 50% as brilliant as it is in the first. There is absolutely no brightness if it goes by during the fourth hour.
2. Radar motion sensor
Doppler sensing, which detects moving objects, is the basis for radar sensing, which turns on street lights. A slight moving object will also cause the induction effect since sensitivity is raised. The integrated solar street light uses 50W of power and activates in full-light mode when people walk by. The street lamp loses 1/5 of its initial power, or 10W, after a person has been gone for 30 seconds. The detecting range is between 8 and 10 meters. integrated solar street lights significantly reduce electricity consumption. With higher sensitivity, a longer sensing range, and a superior sensing effect, radar sensing is a recent development in sensing technology that is more intelligent than human infrared sensing and voice-controlled sensing. Angled light can pass through thin glass and wood with no dead zones. The integrated solar street light with a radar motion sensor is undoubtedly more expensive than one with a PIR sensor and a timer.
3. PIR sensor
By sensing temperature changes in the surrounding area, infrared induction activates street lights using the pyroelectric exploration concept. It will respond as soon as a person or other infrared-emitting items enter its detection range. Only 3-5m is required for sensing. The lamp automatically switches to the strong light mode when someone walks by, activating the infrared sensor. The strong light typically lasts for 30 seconds. The light automatically shifts to the dim mode when someone walks outside the sensor range, waits until someone else approaches, and then switches to the bright mode.
We've covered three strategies for integrating solar street lights that use less electricity. What are the benefits of solar street lighting with integrated motion sensors?
Energy saving and environmental protection
Energy conservation and environmental protection are the two key benefits of induction integrated solar street lights. The switch will automatically turn on the load when a body reaches the induction area. The induction light will continue to operate if the human body does not move and remains active; if it does, the street lamp will automatically reduce its power or switch off. It works well to prevent energy waste by turning on the lights when people enter a room and turning them off when they leave.
Automatic metering
The sensor will be disconnected when the light is intense during the daytime due to the automatic metering design of the sensor street light switch.
Reliable sensing
The thyristor circuit is used because of its high level of safety, broad sensing capability, and good sensing performance.
