LED Tester | Christmas Light Tester - LISUN

Summary: Compared with common integrating sphere , the all-new 3m  integrating sphere has many improvements. LISUN engineers add the infrared anti-pinch device, the cross laser positioning and adjustable multifunctional holder base in the integrating sphere. The world famous company Sharp Laboratories of America and some other  European companies have purchased the 3m integrating sphere. Here are some photos that show the installation, appearance and properties of the new 3m integrating sphere. The process of the sphere splicing: The painting for integrating sphere internal coating. This is the most important part and usually need about 7 days to finish all the paiting procedure. Only 3m integrating spheres need to be painted on the client side. Other spheres will be painted well before delievery. Install the motor and other accessories for automatic opening and closing the sphere: Here is the infrared anti-pinch device. It will automatically stop closing the sp...

Fair: HKTDC Hong Kong International Lighting Fair 2019 (Autumn Edition) Date: 2019/10/27-2019/10/30 City: Hong Kong Exhibition Hall: Hong Kong Convention and Exhibition Centre Organizers: Hong Kong Trade Development Council Booth of LISUN: ED-A01 Hong Kong International Lighting Fair is held by Hong Kong Trade Development Council since 1999.

High/Low temperature & humidity test chamber is used to simulate a actual temperature and humidity environment which it may caused any influence for surrounding objects，due to electronic products widely application in various occasions, in order to design better product which meet relevant environmental standards, the temperature and humidity test has become an necessary test items, and high/low temperature and humidity test chamber widely used in many different industries such as aerospace product, electronic instrumentation, materials, electronic products and various electronic components, this environmental test chamber used to checking working performance of DUT in high temperature, low temperature or hot and humid environment. This article focuses on discussion environmental climatic chamber application on the LED lighting industry application. Lisun Electronics (Shanghai) Co., Ltd is one of best LED lighting test equipment supplier, our products involved p...

IEC 60529 IP code is a coding system to indicate the degrees of protection provided by an enclosure against access to hazardous parts, ingress of solid foreign objects, ingress of water and to give additional information in connection with such protection IP code includes 4 digits, like IP23CH. IP short for ingress protection; numeral 2 stands for first characteristics and can be instead by numerals 0 to 6 or letter X (not requires to specified), it indicates enclosure against ingress of solid foreign; Numeral 3 standards for second characteristics and can be instead by numerals 0 to 8 or letter X (not requires to specified), it indicates enclosure against ingress of water with harmful effects. Letter C is additional letter, indicates enclosures access to hazardous parts, can be instead by letters A, B, C and D, but this characteristic can be ignored; Letter H is supplementary letter, can be instead by letters H, M, S and W, but this characteristic can be ignored. In this article, we ...

Glow wire test is to test the stability of electrical and electronic products during working. And the hot wire itself is the resistance wire ring with fixed size. When doing test, the wire ring should be heated up to the specified temperature by electricity, so that the time when the top of the wire reached the sample can meet the time standard required, then observe and measure its state. The test range depends on the specific test procedures. When do the test for the determination of the burning of hot wire (GWFI) in a solid electrical insulation material or other solid materials test sample, there is a detailed requirement for the hot wire test method in standard GB/T 5169. Test results can be used for relative comparison of the performance of the above various materials, namely, the ability of the flame extinguished when remove the electricity heated hot wire; and the ability to not produce burning or glowing particles for the beneath bedding layers and packaging paper of the ...

As well as we know that for the LED luminaires lumen test, the CIE121: 1966 Clause 6.1, CIE127-2007 Clause 6.2 and IES-LM-79-08 Clause 9.0 are mentioned two luminous flux test method: the first is adoption  integrating sphere +photometer or spectrometer(recommend by CIE121: 1966 Clause 6.1.1, CIE127-2007 Clause 6.2.and IES-LM-79-08 Clause 9.0), this kind of test method is relative measurement method on lumen test; the second is photometric method which is adoption  goniophotometer , this kind of test way is absolute measuring method. If adoption integrating sphere and photometric method to test same one LED lamp, we will find luminous flux data of two test method have big difference. This article is mainly discuss luminous flux test difference at integrating sphere and goniophotometer. The principle of integrating sphere measuring total luminous flux by calibrated standard lamp. Due to there will be use a calibrated standard lamp, so there’s no need to know the integrating ...

IES LM-79-08 “Electrical and Photometric Measurement of Solid-State Lighting Products” as the exclusive international standard for measuring the total luminous flux, electrical power, luminous intensity distribution and correlated color temperature (CCT), color rendering index (CRI) and other colorimetric parameters of solid-state lighting products (SSL), it highlights the total luminous flux of SSL products should be measured with the  integrating sphere  system or  goniophotometer . So the integrating sphere, as one of the main measuring instruments of SSL products, it can reduce and eliminate the measurement error caused by the difference of light shape, divergence angle and responsivity of different positions on the detector. Its design and manufacturing process is especially important and will directly affect the accuracy of test results. Here we take a look at the current status of the production of integrating sphere technology in China market. The Status of ...
