What Traps Should You Pay Attention To When Buying Solar Street Light

Nowadays, solar street light is widely used, but due to the different market prices of solar street light, the quality of solar street light manufacturers are also different. Therefore, it will cause some solar street lights to have a serious impact on their use. So when buying solar street lights, what problems should be paid attention to avoid being deceived? Second Sun, the solar street light manufacturer will share with you:

1. Counterfeit Chips; Low-end Chips

The core of LED lamps is the chip, which directly determines the performance of the lamp. However, some unethical manufacturers take advantage of their customers' unprofessionalism and use low-cost chips to enable customers to purchase low-quality products at a high unit price, thereby generating direct economic benefits. Losses and serious quality hazards caused by light-emitting diode lamps.

2. The Problem of Copper Wire As Gold Wire and Controller

Many LED manufacturers are trying to develop copper alloys, gold-plated silver alloy wires and silver alloy wires to replace expensive gold wires. Although these substitutes are superior to gold wire in some properties, they are less chemically stable. For example, silver wires and gold-plated silver alloy wires are susceptible to Sulfur/Chlorine/Bromination/Corrosion, and copper wires are easily oxidized and sulfided. For encapsulated silica gels similar to absorbent and breathable sponges, these alternatives make the bonding wires more susceptible to chemical attack, reduce the reliability of the light source, and make the lamp beads easier to disconnect.

If the controller fails in the solar road lamp controller during the test and inspection process, "the whole lamp is off", "the lamp is not switched on time", "partially damaged", "a single LED bulb is dead" and "the whole lamp is dead" Blink".

3. Poor Heat Dissipation Design, Exaggerated Configuration Parameters

In terms of heat dissipation design, the service life of semiconductor devices will be doubled every time the PN junction temperature of the light-emitting diode chip is increased by 10 degrees. Due to the high brightness requirements of LED solar street lights, the requirements for the use environment are also higher. If the heat dissipation problem is not solved well, the light-emitting diode will age quickly and the stability will be reduced. In addition, unreasonable configuration often leads to the use of expectations.

4. Configure Virtual Standards and Exaggerate Configuration Parameters

The popularity of solar street lights is also accompanied by a decline in prices and profits. Fierce competition has also prompted many solar street light manufacturers to show that the standard cutting angle, wattage, solar wattage, battery capacity, and even parameters of solar street lights are all wrong. Of course, this is also the result of customers repeatedly comparing prices, which requires low prices and is related to the practices of some manufacturers.
