How to test the quality of the solar street light I purchased?
To test the quality of purchased solar street lights, the following aspects can be considered:
1. Optoelectronic performance testing: Under standard testing conditions, measure the maximum output power of the solar panel and record relevant data. By comparing the actual output power with the nominal power, the photoelectric conversion efficiency can be calculated to verify the photoelectric conversion efficiency of solar street lights and ensure their normal operation.
2. Lighting performance test: At the installation site of solar street lights, use instruments such as illuminance meters and brightness meters to measure their brightness and illuminance distribution, evaluate lighting uniformity and visual comfort, and evaluate the lighting effect of solar street lights.
3. Controller Function Test: The controller is the core component of solar street lights, responsible for controlling the discharge of batteries and the illumination of LED lights. It should be functionally tested to ensure its normal operation.
4. LED brightness test: Use a photometer to measure the brightness of LED lights. A higher reading means that the LED lights have higher brightness and can provide better lighting effects.
5. Durability test: Expose solar street lights to environmental conditions such as high temperature, low temperature, and humidity, and observe whether they can work properly to test their durability.
6. Functional loss inspection or actual power/current detection: The functional loss, actual power, and current of solar street lights must comply with the product model and testing standards.
7. Internal structural quality and core component inspection: Check the internal structure and components of solar street lights. The route should not encounter sharp edges, hot components, fitness and sports components to prevent damage to the insulation layer. The internal structural connection of solar street lights should be fixed, and CDF or CCL components should comply with regulations.
8. Stability test: For portable pillar solar street lights, they should be placed on a tilted surface at a certain angle to the plane, and the power plug should be placed in a harmful area to test whether the solar street lights are stable and cannot be overturned.
9. Charging and discharging detection: Charge and discharge according to the instructions, and check if it meets the requirements.
10. Waterproof test: Conduct an IP55 anti sprinkler test, spray the solar street lamp with tap water for two hours, and check if it is affected.
How do motion sensors work in solar street lights?
As for the operation of motion sensors in solar street lights, motion sensors (also known as sensors) play a role in saving battery energy consumption in solar lights. Specifically, the motion sensor will only turn on the light when necessary. In solar projectors, motion sensors typically use PIR sensors to detect motion. This type of sensor has the functions of detecting range, distance, delay time, and light sensitivity, which can be easily adjusted and will not pick up the movement of random objects such as common outdoor branches or windblown objects. The detection distance allows for adjusting the distance at which the detector can receive motion, while the delay or detection time setting determines the amount of time the illumination will light up after detecting motion. Most solar projectors with motion sensing can capture motion within a wide angle of 120-180 degrees and a distance of approximately 8-10 meters.
Please note that testing the quality of solar street lights requires a certain amount of professional knowledge and equipment. If you do not have the relevant conditions, it is recommended to hire professional personnel for testing.
