Solar street lights need to be tested for what performance
Solar street lamps will do a lot of tests before the design and production, to test whether their performance meets the national quality requirements and standards, whether it meets the basic specifications and safety standards of solar street lamps, etc., the quality inspection before delivery is more strict and rigorous. Solar street lamps generally need to test the following performance.
1. Photoelectric performance test
The test can effectively detect whether the actual parameters of the solar street lamp have the problem of virtual mark. The luminous efficiency, color temperature, color difference, input and output power, and whether the current and voltage are stable can be detected by the test.
2. Quality of core light source of solar street lamp
The quality of solar street lamp LED light source needs to test the lens process evaluation, packaging glue type, whether there are pollutants, bubbles, air tightness evaluation, chip process evaluation, chip graphics and microstructure measurement, defect search, chip pollutants identification, whether there is leakage, whether there is damage.
Lead bonding process evaluation, welding morphology observation, arc height measurement, diameter measurement, lead composition identification, etc.
3. Heat dissipation performance of lamps
The integrated solar street lamp is a whole set of batteries, controllers, and LED light sources in one, with good tightness, so heat dissipation should be taken into account when working discharge. As a new type of energy-saving lamp, only 30-40% of the electric energy is converted into light in the lighting process, and the rest is converted into heat energy.
And the life and quality of the lamp are closely related to the temperature, LED lamp temperature, shell temperature, and heat dissipation temperature will be related to the uniformity of the degree of illumination and quality of life.

4, waterproof and dustproof performance of lamps
Solar street lamps have certain protection level standards, which are generally represented by IP plus numbers. Solar street lamps are usually IP65, IP66, IP67, and must at least reach IP65 waterproof and dustproof level. IP67 level is the highest level of solar street lamps at present.
5. Quality evaluation of solar street lamp power supply
The function of the drive power is to convert the AC mains into a suitable direct current. Reliability, efficiency, power, driving mode, overcharge protection, over-discharge protection, overvoltage protection, temperature negative feedback protection, and other factors should be considered in the selection and design of a driving power supply.
6. Appearance inspection of solar street lamp
Appearance check, size check, material check, assembly check.
7, solar street lamp wind resistance
Solar street lamp is a key factor of the wind resistance of the lamp pole test, because the lamp pole is a certain height, the lamp pole from the material or size ratio should be measured in accordance with the basic data wind resistance coefficient, the general solar street lamp selection is a ten grade typhoon resistance coefficient.
Especially in the coastal typhoon zone and the northwest area with large windblown sand, the wind-resistant design and wind-resistant ability of solar street lamps must be considered.
8, solar lighting lightning protection design performance
Solar street lighting in summer thunderstorm weather, especially pay attention to lightning protection, solar street lighting products themselves are low voltage, equivalent to its own lightning rod, low pole light is very unlikely to be struck by lightning, but high pole light or to consider and test lightning protection performance.
9. Continuous rain and light duration test
Solar street lamps in use process are the main concern of the rainy day not bright lights or light time is short, to reach the desired ideal effect, so the factory in production of the factory will test before the morning light rainy time length, according to the test data, according to different regions and climate differences, setting and debugging days duration rainy daylight lamp solar street lamps, generally 3 to 5 days, Configure high Settings for 5-7 days.
Solar street lamps after the above performance test leave the factory safely, not only to ensure product quality, and manufacturer reputation, but also to ensure the safety and rights, and interests of consumers, to avoid return and exchange, reduce the cost and expenditure of after-sales service.
