You need climatic chamber for testing lamps. Many lamps are exposed to the elements day after day, experiencing sun exposure, rain wash, high and low temperature conversion and other complex climatic conditions, climatic chamber can help you to test their reliability.

Common Test
- Temperature test
The climatic chamber is kept at high temperature and low temperature for 0.5h each, and the cycle is 8 times. The temperature change range of the test chamber is set from -10℃ to 50℃, and the temperature change rate is greater than 1℃/min, but less than 5℃/min.
After the test, observe whether the lamp is damaged, the material is deformed by heat and other abnormal phenomena;
- Impact test
Turn on the power supply, light the lamp for 24h, and observe whether the lamp is damaged, the material is deformed by heat and other abnormal phenomena; dry the surface of the sample after taking it out, and restore it at normal atmospheric pressure and room temperature for 2h for inspection; After high temperature and high pressure test, no surface stripping, discoloration, cracking, material deformation and other abnormal phenomena can occur; After the lighting test, the impact test is carried out under this environment through the relay control of the lamp. The test is set as: lighting 20s, turning off 20s, and cycling 100 times. After Impact test, electrical anomalies such as leakage and light failure cannot occur.
- Constant wet heat test
Switch on the power supply according to the rated input voltage of the LED lamp. The LED lamp is placed in a constant temperature and humidity chamber, and the constant temperature and humidity chamber is set to the relative humidity of 95% and the temperature is 45℃; after the test, the lamp can not occur leakage, lighting is not bright and other electrical anomalies.
- LED lamps vibration test
Lamps after vibration test, can not occur parts fall off, structural damage, lighting is not bright and other abnormal phenomena.
