LED streetlights have been promoted for a long time, and even if they are not widely used now, future LED street lights will surely be the loyal guardians of the road. However, in view of the various problems that arise in the current application process, how to sell LED streetlights and how to sell them has become a concern of more people.
In general, in order to enable the company to better fulfill its after-sales service responsibilities, the street lamp management department will divide the project payment into three enterprises, that is, the prepayment, after installation, and the balance after the warranty, the ratio is about 3:5:2. For the enterprise, whether it is for fulfilling the terms of the contract or for recovering the full amount, after-sales maintenance is a part that must be of great concern.
According to the reporter's understanding, many companies have indicated that the most frequent failure of LED streetlights is still power supply, with a ratio of up to 80. Most of the regular streetlight companies' products are waterproof and dustproof to IP65, and some even reach IP68. The light source is basically not bad. Yang Hongtao, director of Beijing Chengtong Optoelectronics Co., Ltd., said.
It is reported that LED street lights need to be driven by the power supply to turn the high voltage of the mains into low voltage, and this part has a large test of the power supply performance, such as poor heat dissipation, use in extremely cold areas with low temperature environment, or long When the time is running, etc., the power supply may malfunction, so the stability of the power supply needs to be improved. Xiao Zhiyong, vice president of sales at BYD, said.
However, some insiders pointed out that compared with light source devices, domestic enterprises actually have the ability to do a good job of power supply. The key is that the cost cannot be compressed too much. It is necessary to use good quality devices.
Usually, if a street lamp fails, the enterprise needs to first detect it and check various faults. If the drive power fails, the power supply needs to be removed and sent back to the power supply company.
It is reported that the budget for the cost of LED street lamp repair is about 2, but for some products with poor quality, the cost of repairing may reach 5. This installation and disassembly cost is very high, which will cause a heavy burden on street lamps. If the quantity is large, even a company will be dragged down, so the quality of the power supply is critical. An engineer with years of experience in driving power development said frankly.
he Molded Graphite blocks produced by our company are also called Carbon Graphite Blocks, which can be divided into extruded graphite blocks, extruded graphite squares, molded graphite blocks, molded graphite blocks, Isostatic Graphite blocks, and graphite blocks according to different processing procedures. Different particle sizes can be divided into: fine-grained graphite block, graphite square, medium and coarse-grained graphite block, graphite square, coarse-grained graphite block, etc. Strong chemical stability, high temperature resistance, corrosion resistance, strong lubricity, long service life, can be customized according to customers. Needs to be customized according to size.
Henan Kaiyuan special high-purity graphite manufacturer, Large Graphite Block, the use of molded graphite block: widely used in refractory materials and coatings in the metallurgical industry, stabilizers for industrial pyrotechnic materials, pencil leads in light industry, carbon brushes in electrical industry, and batteries in battery industry. Electrodes, fertilizer industry catalyst additives, etc. After deep processing, high-purity graphite can also produce high-tech products such as graphite milk, graphite sealing materials and composite materials, graphite products, and graphite anti-friction additives, which have become important non-metallic mineral raw materials in various industrial sectors.
