How much do you know about the secret of low price of LED street lights?

Strong profitability and strong profitability are the root cause of confusion in the LED street light industry. LED street lamp manufacturer is a solid-state cold light source, which has the characteristics of environmental protection, no pollution, low power consumption, high light efficiency, and long life. Therefore, LED street lamps will become the best choice for energy-saving road lighting. LED street light is a high-efficiency solid-state light source formed based on a semiconductor PN junction that can emit light with weak electric energy. Under a certain forward bias voltage and injection current, the holes injected into the P area and the electrons injected into the N area are in After being diffused to the active area, photons are emitted through radiation recombination, which directly converts electrical energy into light energy. In an industry, this kind of thinking has already penetrated upstream, midstream, and downstream, forming a complete chain of benefits, and seizing loopholes in the external market.

Cause market chaos. The low price of LED street lights has no good products on the market. Let's first analyze the composition of the led street light system. The main components are composed of battery board assembly, battery/lithium battery, smart controller, LED light and light pole. In general, these parts, why the market is chaotic, prices are chaotic? Take the standard configuration of 6m A-arm + 30W as an example of the conventional product of New Countryside: some offer 1,000 yuan/set, some offer 2,000 yuan/set, some offer 3,000 yuan, and Taobao even 600 yuan. Unlike other products, the value-added factor of this brand is basically negligible, and there is no highly recognized whole lamp brand in the industry, so it is impossible to mention brand value-added. The market competition is so fierce that no one will push the business outside, and no one will become a loss-making philanthropist. No standard, no bottom line and cutting corners are the root causes of price confusion.   First, the solar panels of the solar panel assembly LED street lights can be fixed in size, which makes it impossible for manufacturers to cut corners, unless some manufacturers use junk chips to produce solar panels, but this will not save a lot of money. But there are exceptions, more creative than you think, paper solar panels. The fraud was not intentional, and people were somehow protected by a piece of glass.  Second, the battery gel battery uses the virtual standard battery capacity method to take a shortcut, but the long-time buyers have also learned to directly ask the size and weight, regardless of the manufacturer's capacity. Buyers think this will prevent manufacturers from cutting corners, but you underestimate the innovative ability of many people, and the innovative ability of many dishonest manufacturers in gel batteries makes cement a matter of course. Or use refurbished gel batteries.   Third, with the continuous development of LED street lights, lithium batteries are slowly turning into lithium batteries. At this time, for the opportunity to make money, unscrupulous manufacturers used 20Ah lithium battery fake standard capacity to simulate 80Ah to customers, and made a lot of profits. From 2014 to 2016, many manufacturers made millions or even billions of lithium batteries. Slowly eat a lot of losses, and many buyers also know how to count the number of batteries in the number kernel to identify the capacity. However, since virtue rises by 1 foot and vice rises by 10, this method is always more difficult. Take a 12V 60Ah lithium battery as an example: a normal 3.7V 2Ah battery, 60Ah÷2Ah×3 u003d 90 cells. When you learn that the capacity of the 90-cell battery is 12V60AH, you need to upgrade again. Yes, the battery core will give you 90 batteries, but silently replace you with 3.7V1AH. At this time, the capacity is only 30AH, which can kill three to four hundred costs at a time. For bad businessmen, this may be profit, or it may be nuclear weapons that occupy the market. Even more arrogant, the innovation of the people is coming.
