According to the official website of Henan Provincial Bureau of Quality and Technical Supervision on April 26, the Bureau conducted product quality supervision and inspection on 20 products in the first quarter of 2017. Among them, 9 batches of LED lighting products for road lighting produced by 7 enterprises in Zhengzhou, Xinxiang, Anyang, Nanyang, Jiaozuo and Hebi were randomly selected, and 2 batches of products did not meet the requirements of the standard. This spot check is based on GB/T 24907-2010 "Performance Requirements for LED Lamps for Road Lighting", GB 7000.1-2015 "General Requirements and Tests for Part 1 of Lamps", GB 7000.203-2013 "Lamps Part 2-3" :Special requirements for roads and street lighting" and "The first batch of LED lighting products for road lighting in 2017, the implementation plan for supervision and spot checks in Henan Province", marking, anti-shock protection, lamp power, power factor for LED lighting products for road lighting Projects such as initial light efficiency, color characteristics, and harmonic current were examined. After sampling, there are 7 batches of products that meet the standard requirements; 2 batches of products of Xinxiang Tianyi New Energy Technology Development Co., Ltd. do not meet the requirements of the standard and involve harmonic current projects. The Henan Provincial Quality Supervision Bureau stated that it has instructed the relevant provincial and municipal directly-administered counties (cities) quality and technical supervision departments to handle the unqualified products and their production enterprises in this spot check according to relevant laws and regulations.
Powell Optical glass prism is also called laser linear generator lens. Unlike cylinder lens, the dome of Powell optical glass prism is actually a complex two-dimensional aspheric curve, which will produce a lot of spherical aberration and redistribute light along the line; Reduce the light in the center area while increasing the light level at the end of the line, transforming the laser beam into a uniform straight line. Cylindrical Lens will produce poorly illuminated lines with fading edges and hot spots in the center, while the straight lines produced by Powell Optical glass prisms have uniform energy distribution and uniform light distribution along the line.The Optical Prisms provide uniform energy distribution along the entire length of the line.
Powell Optical glass beamsplitter are currently widely used in industrial and research applications, where uniform intensity distribution is essential, because lasers are used as illumination sources, or, for example, in material processing, when the entire area irradiated by the laser must be processed to be uniform and equal The way. Powell lenses will produce a very uniform line of illumination for a variety of machine vision applications; from biomedical and automotive assembly to chocolate chip cookie production.
