IP Waterproof and Dustproof Rating Test

IP Waterproof and Dustproof Rating Tes t   Purpose of the test: to assess the ability of the material to prevent solids and liquids from entering the external shell Detection range: electrical and electronic equipment, automotive aircraft and other parts   IP level (waterproof and dustproof) definition IP waterproof and dustproof, refers to the protection level of electrical equipment, in accordance with its ability of preventing external objects intrusion, waterproof, moisture-proof and dustproof characteristics to be graded. The external objects include tools, human fingers, etc. which are not accessible to the live parts of the lamp to avoid electric shock. IP protection level is composed of two figures, the first number represents the level of dustproof ability for lamps, and the ability of preventing foreign objects intrusion; the second number represents the level of anti moisture and water for lamps. The larger the number is, the higher the degree of protection is. For ...

High and low temperature test

High and low temperature test In natural environment, temperature and humidity are two indivisible natural factors. Due to different geographical locations in different regions, the temperature and humidity effects generated are also different. This test is used to confirm the products’ adaptability during storage, transportation and usage in the climate of some certain temperature and humidity. Severe levels depend on the high / low temperature, humidity and the time of exposure. High temperature test is introduced in detail: this test is used to determine the adaptability of the products to store, transport and use under the conditions of high temperature and climate. The severity of the test depends on the temperature of the high temperature and the duration of the exposure. Reference test standards: GB/T 2423.2, IEC 60068-2-2, IEIA 364, MIL-STD-810F and so on. Low Temperature Test: This test is used to confirm the products’ adaptability of storage, transportation and usa...

Integrating Sphere Work Principle

Integrating Sphere Work Principle If the total flux of light enter integrating sphere is Φ, irradiate on the inner wall area S3 of the integrating sphere. The light diffuse on the surface of the inner wall several times. Examine the illumination of the inner wall at any point M. Since the light entering the integrating sphere directly illuminates at S3, one part of the light diffused by each point on the S3 will irradiate on the observation M point directly, the illuminance of all these light illuminated to point M is called the direct illumination, which is denoted by E0. In addition, there are some light diffused from S3 to each point on the inner wall of the integrating sphere by multiple diffuse reflections and then reach to point M, the sum illuminance of this part light is called multiple diffuse reflection illuminance, which is denoted by E∑. Thus, the illuminance E of the observation point M is the sum of the two parts of the illuminance: E=E0+E∑     ...
