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 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...

Lisun Electronics Engineers went to Hungary to install Goniophotometer for our Hungary customer.   Zengővári Lighting Ltd has been manufacturing lighting products for 20 years in Hungary. In October 2012, Zengővári Lighting Ltd purchased Lisun Rotation Luminaire Goniophotometer (LSG-1800 ) for lamp testing. Our Engineers spent three days in providing installation and training service to customers. The first day, Zengővári engineers carefully reviewed the drawing provided by Lisun Enigneers, then they installed the test system, and calibrated and debugged the instruments in accordance with CIE standards. The next day, Zengővári staff from technical department together with Lisun Engineers used the calibrated system to test some lamp samples, and they found the test result was very close to the rated specifications. On the last day, Lisun Engineers gave a detail introduction and training for Zengővári staff about the basic knowledge a...
