【Solar Light Factory School】Four traps to pay attention to when purchasing solar street lights

Nowadays, both solar street lamps and LED street lamps are important lighting facilities for urban development. The quality of solar lamp factory lighting gained from 15 years of industry experience is the most concerned place for outdoor lighting projects, not the price of solar street lamps and LED street lamps. But now the market price of solar street lamp and street lamp is different, and the quality of solar street lamp manufacturers is uneven. Many reasons are that in the Chinese market, LED street lamp manufacturers and solar street lamp manufacturers have low patent awareness and lack of innovation. The price war in the industry has caused manufacturers to continue The cost reduction in terms of materials and craftsmanship has led to a major negative impact on the quality of LED solar street lights. It is often seen that the street lights will dim after a period of use or have various problems. This is more difficult for street lamps, such as outdoor high-altitude devices, to maintain. For street lamp managers, unstable product quality makes maintenance costs higher. Today, the solar-powered factory lighting specifically analyzes the five traps that should be paid attention to when purchasing solar-powered LED street lights. First, counterfeit chips, low-end chips The core of LED lamps is the chip, which directly determines the performance of the lamp! However, some unscrupulous manufacturers take advantage of customers' unprofessionalism and use low-cost chips from the perspective of cost, which causes customers to buy low-quality products at a high unit price, causing direct economic losses and causing serious quality risks to LED lamps. The chips used in the lighting of the solar lamp factory are Epistar chips imported from Taiwan and Bridgelux chips imported from the United States. Second, configure false standards and exaggerate configuration parameters. The popularity of solar street lights is also accompanied by the reduction of price and profit. The fierce competition has also led many solar street light manufacturers to cut corners and false standard product parameters, such as light source wattage and solar panel watts. Data, battery capacity, and even materials for solar street light poles are all in problems. Of course, this is also caused by customers' repeated price comparisons and low prices. It is also related to the practices of some manufacturers. Third, poor heat dissipation design and unreasonable configuration. In terms of heat dissipation design, every time the PN junction temperature of the LED chip increases by 10 degrees, the life of the semiconductor device will be reduced by multiples. Due to the high brightness requirements of LED solar street lights, the use environment is relatively harsh, if the heat dissipation is not solved well, it will quickly cause LED aging and reduce stability. In addition, unreasonable configuration often leads to specific usage conditions that fall short of expectations. Fourth, the problem of copper wire pretending to be gold wire and controller. Many LED manufacturers try to develop copper alloy, gold-clad silver alloy wire, and silver alloy wire to replace expensive gold wire. Although these alternatives are superior to gold wires in some properties, they are much worse in terms of chemical stability. For example, silver wires and gold-coated silver alloy wires are susceptible to sulfur/chlorine/bromination corrosion, and copper wires are prone to oxidation and sulfide. For the encapsulated silica gel similar to the water-absorbent and breathable sponge, these alternatives make the bonding wire more susceptible to chemical corrosion, the reliability of the light source is reduced, and the use time is long, and the LED lamp beads are more likely to break and die. Regarding the solar street light controller, if the controller is faulty, during the test and inspection process, 'the whole light is offThe whole lamp flickers and ignited.” Buy high-quality LED solar street lights, preferably solar lights factory lighting LED solar street lights, LED solar street lights that can stand the test! Especially suitable for municipal solar street light projects and new rural solar street light projects.
