【Solar Lamp Factory School】Five things that engineering companies need to pay attention to when purchasing LED street lights

Nowadays, LED street lamps and solar street lamps are both 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 price of LED street lamp market is different, and the quality of LED 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 to The reduction of costs in terms of materials and craftsmanship has led to a major negative impact on the quality of LED street lamps. It is often seen that street lamps 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 lamp factory lighting specially analyzes the five traps that should be paid attention to when purchasing LED street lamps. First, counterfeit chips The core of LED lamps is the chip, which directly determines the performance of the lamp! However, some unscrupulous merchants take advantage of customers' unprofessionalism and use low-cost chips to make customers buy low-quality products at high unit prices, causing direct economic losses and causing serious quality risks to LED lamps. Second, the enthusiasm of configuring false standard LED street lights is also accompanied by the reduction of price profits. The fierce competition has also led to many businesses starting to cut corners and false standard product parameters. This is also caused by customers' repeated price comparisons and lower prices. , Is also related to the practices of some manufacturers. Third, poor heat dissipation design. In terms of heat dissipation design, the life of the semiconductor device will decrease by multiples every time the PN junction temperature of the LED chip increases by 10 degrees. Due to the high brightness requirements of LED 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. Fourth, copper wire pretends to be gold wire. Many LED manufacturers try to develop materials such as 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. In terms of driving power supply, if the power supply fails, the phenomenon of 'the whole lamp is offFifth, the design of the light distribution system of the street lamp is unreasonable. In terms of optical design, if the design of the light distribution system of the street lamp is unreasonable, the lighting effect is not ideal. Problems such as 'bright under the lightThe blackening of LED light sources is a common problem encountered by major LED companies. Most materials in lamps need to be checked for substances that affect the life of the light source. In addition, it is worth noting that the safety issues are also the same, the street lamp power supply has no leakage protection; the street lamp ballast quality is shoddy; the circuit breaker has not been tested for sensitivity, and the rated trip current is selected too large; the cable metal sheath is used as PE The main trunk line has complex technology and low reliability; the problem of low IP waterproof and dustproof level. Buy high-quality LED street lights, preferably solar-powered factory lighting LED street lights, LED street lights that can stand the test!
