The Analysis Of The Led Street Light Price Why There Are Uneven?

1. Different raw material process. As the manufacturers' patent awareness is not strong, innovative enough, industry price war led to manufacturers continue to reduce costs in materials, processes and other aspects, which brings to the quality of LED street lights

This has a major impact on the quality of LED street lights, often see the street lights dark after a period of time.

2. The overall price of poor quality led street lights is higher than that of high quality led street lights. Due to the easy damage, LED street lights need to be taken off and transported back to the factory for various tests. This is difficult to install and even more difficult to maintain for LED street lights such as outdoor high level installations, for street light For managers, the inconsistent quality of the product makes maintenance costs climb high.

3. Poor design of the light distribution system of street lights

　　In terms of optical design, if the light distribution system of a street light is not designed properly, the lighting effect will not be satisfactory. In the test, there will be "bright under the light", "dark under the light", "zebra crossing", "uneven illumination", "yellow circle" and other problems. "Yellow circles" and other problems.

4. The problem of the life of the light source in the luminaire. Most materials in the luminaire need to be carried out to affect the life of the light source, so that the warranty period is different.

5. Power supply failure. Drive power supply, if the power supply failure, test and inspection process, there will be "the whole light off", "part of the damage", "individual LED lamp beads dead light", "the whole light flickers false light". The phenomenon of "the whole light flashing false light".

6. Safety faults. Safety problems also deserve serious attention: street lamp power supply without leakage protection; street lamp ballast quality to substandard; circuit breaker without sensitivity check test, rated breaking current selection is too large; the use of cable metal sheath for PE total trunking process complex, low reliability; IP waterproof and dustproof level is too low.

7. Poor thermal design. Thermal design, the PN junction temperature of the LED chip every 10 degrees higher, the life of the semiconductor device will be multiply decreasing. Due to the high brightness requirements of LED street lights, the use of harsh environment, if the thermal solution is not good, will quickly lead to LED aging, stability is reduced.

So how do we identify the led street light module is good or bad?

Generally now led street light module internal core is composed of these three parts: parameters configuration, chip, copper wire and other components; so the price will also fluctuate with these three blocks.

1. Incomplete configuration.

　　LED street light of the hot also accompanied by the price of profit reduction, the fierce competition has also led to many businesses began to appear jerry-built false label product parameters, which is also the customer repeatedly than the price, the requirement of low prices led to, but also with some manufacturers' practices.

2. chips are not up to scratch.

　　The core of LED lamps and lanterns is the chip, which directly determines the performance of the lamps and lanterns! However, some unscrupulous businessmen use the customer's unprofessional, from the above cost considerations, the use of low-cost chips, so that customers with high unit prices to buy low-quality products caused by direct economic losses, and LED lamps and lanterns caused by serious quality risks.

3. copper wire being impersonated or swapped.

　　Many LED manufacturers have tried to develop such products as copper alloy, gold covered silver alloy wire and silver alloy wire to replace expensive gold wire. Although these alternatives are superior to gold wire in some properties, they are much less chemically stable, e.g. silver and gold-clad silver alloy wires are susceptible to sulphur/chlorine/bromination corrosion and copper wires are susceptible to oxidation and sulphuration. For encapsulated silicone, which is similar to an absorbent and breathable sponge, these alternatives make the bonding wire more susceptible to chemical corrosion, the reliability of the light source is reduced, and over time, the LED beads are more likely to break and die.

So, according to the city function for outdoor lighting planning, outdoor lighting design and urban architecture and led street light module to meet each other, different functional nature of the street and lot, the specific environment and buildings, but also should be different brightness and style requirements. There have been many safety accidents in cities across the country due to night lighting, so safety is an issue we have always focused on. Lighting project planning should be timely gate-keeping led street light quality and planning, to ensure the safety of electrical construction.
