LED Tester | Christmas Light Tester - LISUN

How to effective to measuring LED lamp Start, Run up time and Flicker Due to the LED solid-state lighting products have good luminous efficiency, long life and high reliability unique characteristics, so it's became more popular by markets and customers. But at the same time, the LED solid lighting have fast response characteristics, it haven’t thermal inertia and afterglow effects, like traditional lamps, so it have big influence by current fluctuations, the current fluctuations affect the luminous flux output directly, the lighting flashing is the external expression of luminous flux change, that caused more and more people focus on lighting flashing issue. Dated 14th December, 2012, the EU officially released the (EU) NO 1194/2012 rules <Implementing rules of the European Parliament and the EU Council Directive 2009/125/EC on the eco-design requirements of directional lights, LED lights and related equipment requirements>.Compared with <European Parliament and Counc...

Similarities and Differences between Photometric Measurements of Goniophotometer and Integrating Sphere for Solid State Lighting Products According to the requirements of the LM-79 optical testing standards applicable to the widest range in the world, although there are many photometric measurements for light sources and lamps are available, but these standards are dedicated to the measurements for light sources and lamps. Because the form of current SSL products are lamps or luminaires, and LED in the luminaires is not easy to be replaced or separated, the existing standards cannot be directly applicable to SSL products, which requires the use of absolute photometry measurements. The photometric information required for SSL products is usually the total luminous flux (lm), luminous efficiency (lm/W), luminous intensity (Candela) in one or more directions, chromaticity coordinates, correlated color temperature and color rendering index. There are two kinds of photometric measurement me...

LISUN engineer visit several customers in Russia this time. And the customer we discussed today purchased a LSG-1800B Rotation Luminaire Goniophotometer (Big Size) from LISUN this time. LISUN engineer stay 2 days in our customer’s company for the installation and training. The customer is enthusiasm, and they expressed satisfaction with our service finally. It’s a happy trip here.

Analysis on the Status of Certified LED Ball in USA Energy Star Energy Star certification (Energy Star certification) is a certification which can adapt to the requirements of the United States Energy Department. In addition to UL, FCC certification, it is the most popular certification of lighting products to enter the United States market,. UL reflects the goods safety performance, FCC reflects the electromagnetic compatibility of products, while the Star Energy certification reflects the goods energy saving performance of the products. Especially for the current global energy shortage, the United States energy Department has promulgated a series of energy saving plan, and the promotion of energy saving products is the main activity. Dated on October 2015, the United States on the market with a total 2995 bulb lamp products obtain the United States Energy Star certification, mainly used to replace the 25W, 40W, 60W and 100 watt ordinary lighting with incandescent, which won the 1563 ...

Equivalent Test Between Normal & High Frequency Fluorescent Lamp and LED Tube Comparing with traditional fluorescent lamp, the LED tube have high light effects, low power consume, long life time and stable luminous efficiency advantages etc. At the same time, for the LED tube performance testing is became more simple, in recent years more and more customers has chosen the LED tube to replace fluorescent lamp. Due to the main lighting products are consist of traditional fluorescent lamp, like the CFL and fluorescent lamp are still occupy a large part of market, it's impossible to replace all of them immediately, specially at the business centre and market still have many fluorescent lamps and compacted lighting products; if replace all fluorescent lamp to LED tube, it's need lots of tome and huge cost, the most important is this way can't be approved. In order to make replacement work more effective, the IEC issued the IEC62776 standard dated December of 2014, this stand...
