Recently, the Jiangsu Provincial Quality Supervision Bureau released the quality analysis report of LED lighting products and energy-saving lamp products in the first quarter of 2014. This supervision has inspected 85 batches of energy-saving lamp products and qualified 59 batches, with a pass rate of 69.4%. The pass rate of LED lamps is slightly lower, and the pass rate of 103 batches is 60.2%. Among them, the pass rate of 53 batches in the production field is 88.7%, and the pass rate of 50 batches sold in the market is only 30%, and there are many quality problems.
In this sampling, the items that failed LED lights were mainly focused on electromagnetic compatibility. Shi Chaoyang, senior engineer of the National Semiconductor Lighting Product Quality Supervision and Inspection Center, said that electromagnetic compatibility mainly affects the interference of other household appliances when the LED lamp is running. If it fails, it may cause the power distribution system or other electronic and electrical products connected to the system. Can not work properly, such as the TV image is not clear, audio equipment noise. What is more serious is that if the electromagnetic compatibility unqualified products are installed in batches, the electrical equipment will overheat, generate vibration and noise, and cause the insulation to age, shorten the service life, and even cause malfunction or burnout.
Among the 103 batches of LED lighting products sampled, the pass rate of electromagnetic compatibility project was only 60.2%, which was 9.2 percentage points lower than that of energy-saving lamps. The incandescent lamps did not have electromagnetic compatibility problems. Therefore, the electromagnetic compatibility of LED lighting products needs to be further improved.
The test results show that the qualification rate of electromagnetic lighting project of Jiangsu real estate LED lighting products is as high as 87%, while the qualified rate of LED lighting products produced by other provinces and cities is only 29%, and the manufacturers of these unqualified products are mostly from Zhongshan, Foshan and Jiangmen, Guangdong. Waiting for the place.

Intergrated Solar Street Light means the Solar Panel and head of light are intergraged together,just show as two opposite sides.
the advantage contains :no need to lay cables and ac power supply,just supply the power with sunlight,in case of no electricity charges; DC power supply,photosensitive control.
