Not long ago in order to understand our solar Caoping Deng production processes and technologies, including Zhejiang, Guangdong, Jiangsu, Shandong and Beijing and other places of the 26 solar Caoping Deng manufacturers were related to technical advice, and to a more intuitive understanding of At this stage the features of the product, and some contact the manufacturer was now on the market the more common models of solar Caoping Deng samples. In the conventional use of the samples testing process, we found a number of almost all products are existing problems, of which solar Caoping Deng's efficiency is particularly obvious. After testing the same working environment under the same products, Cao Pingdeng Open conditions, LED brightness can be luminous and not the same time, the most obvious gap is three times more. 明什么呢？ The same products in such a question as to what can be » The consistency of bad products.
Will be solar Caoping Deng split, we found that most of the solar Caoping Deng mainly by the structure of control circuits, solar panels, LED, rechargeable batteries and lamps, such as shell composed of five parts, in addition to four other shell lamps Parts of the material will be directly or indirectly, the decision of the quality of the product. Comparing key part of which is to control the circuit, it has a direct impact on the solar Caoping Deng's working conditions. After a full study will be solar Caoping Deng principle of the circuit, will be the largest power in the 1 v following the parameters of the product than the right, approval to the most appropriate data. According to this data will be designed a charging circuit, driving circuit, photosensitive control and frequency modulation circuit fully integrated solar Caoping Deng controller, the controller on the market will make most of the solar Caoping Deng products in the efficiency and On the consistency has made significant improvement. Below provide the control of the relevant parameters and characteristics for your reference:
