With the technological progress and industry maturity of LED chips and solar modules, the price of solar street lamp industry has developed by leaps and bounds, and the market of solar street lamp has expanded dramatically. At the same time, the price of solar street lamp system is varied, making the purchasing users dazzled. The main reason is that some manufacturers' intellectual property rights protection meaning is not strong, innovation and research and development power is insufficient, the homogenization of competition will inevitably cause price war, it is inevitable to appear bad manufacturers "dirty" sales, harm consumers, buyers have to be careful of these "traps".
In view of the design and quality requirements of solar LED street lights, the company has been summarized in this network series of articles, readers can identify the price of bad manufacturers according to some of the previous knowledge:
Solar LED street lights common "trick" :
First, it is high standard low collocation. Bad manufacturer false standard parameters, such as power false standard, lamp pole thickness reduction and so on. Reduced configuration is difficult for customers to detect under normal circumstances. It is also used by bad manufacturers to lower prices. The primary means of disrupting the market.
Second, chip brand and quality. LED chips directly determine the performance and price of lamps! Some undesirable businessmen use customers not professional, with small manufacturers of chips posing as famous brand manufacturers of chips, or with manufacturers of low-grade chips posing as high-quality chips such as copper wire connection posing as gold wire connection, cheating consumers caused by customers to buy low-price products at a high price.
Third, it is to reduce the cost at the expense of scientific light distribution system design. Bad manufacturers to reduce costs. Not hesitate to change or even cancel the lighting system, seriously affect the lighting effect. Cause "light under", "light under black", "zebra crossing", "uneven illumination", "yellow circle" and other problems. These phenomena are difficult to detect without professional testing by professionals.
Fourth, the heat dissipation design is poor. When the PN junction temperature of LED chip increases by 10 degrees, the lifetime of semiconductor device decreases by multiple. It can be said that heat dissipation is an important guarantee to ensure the life of LED street lamps and the quality of use. Bad manufacturers mainly take jerry-cutting measures to reduce costs in this regard, and this harm is found in the use of the original, it is generally needed to use a period of time to see it.
Five, is the quality of power supply. Of the price of power supply and quality and design and element of interior electric equipment choose to have very big concern, not be lamp light is ok. The phenomenon of shoddy goods in this respect is more.
Sixth, the harmful substances in the light source exceed the standard. The blackening of LED light source is a problem that major LED companies often encounter. The main reason is that. There are substances in the components of luminaire that affect the life of light source greatly.
Seven, is the confusion of the concept, such as: solar LED street light can generally adjust the use of power, some manufacturers because the customer is unknown, do not say the use of power, simply say the lighting time to deceive consumers.
