Should be paid attention to when buying solar led streetlight street light billboards

As the led chip and solar module, technological progress and industrial maturity, solar street light industry price appeared a leapfrog development, market surge solar street lamps, at the same time, the price of solar street lamp system is multifarious, make procurement users at sheet

as led chips and solar battery components of technological progress and industrial maturity, the price of solar street light industry by leaps and bounds, solar street lamps market is expanding fast. At the same time, the price of the solar street light system is multifarious, makes buyers dazzling, doing nothing. The main reason is that some manufacturers have no strong protection of intellectual property rights, lack of innovation and research and development of power. Homogeneous competition will inevitably lead to price wars. Inevitably, bad manufacturing chamber of commerce for 'suspicious' sales, harm consumers. Buyers must be careful these 'trap'. According to the design and quality requirements of solar led street light, the author's Mr Zhang series of the network are summarized. Readers may, according to some previous knowledge to identify bad manufacturers 'suspicious' : the price of solar led street lamp common 'catfish'; First of all, high standards and low matching. Error, the maker of virtual tag parameters, such as virtual mark, the thickness of the lamp to reduce power. Under normal circumstances, the customer is hard to find a way to reduce configuration. Bad manufacturers also use this fact to lower the price. Disrupt the market principal means. The second is the chip brand and quality. Light emitting diode chip directly determine the performance and price of lamps and lanterns! Some unscrupulous businessmen use the customer's professional skills, with a small manufacturer as brand-name manufacturers of chip, or use the same manufacturer of lower level as the quality of the chip, such as using copper as gold thread connections, etc. , cheat shenyang traffic signal light pole and consumers, causing the consumer buying cheap products. 。 The third is the sacrifice of science light distribution system design to reduce the cost. Bad manufacturers to reduce costs. Don't hesitate to change or even cancel light distribution system, seriously affect the lighting effect. This creates a 'bright light', 'bright' silenced, 'zebra crossing', 'uneven illumination', 'yellow' and so on. However, if there is no professional professional testing, it is difficult to immediately find these phenomena. Fourth, heat dissipation design is poor. Whenever the light emitting diode chip p-n junction temperature rises of 10 degrees, the service life of semiconductor devices in multiples. Heat dissipation is, as it were, to ensure the service life of the led street lamp and the use of the important guarantee of quality. In this regard, bad manufacturers to cut corners to reduce the cost. This kind of harm, however, did not find at the beginning of the use, can only see in use after a period of time. Fifth, the power quality. The price and quality of power supply and internal components of the electrical design and choose to have a lot to do. It is not enough to turn on the light. The area has many examples of fake and inferior products. Sixth, the light source of the harmful material exceeds bid. Light emitting diode light black is the main common problems in the light-emitting diode company. The main reason is that. Some of the components of lamps and lanterns material will greatly affect the service life of the light source. The seventh is confusing concepts, such as: solar led street lamp power consumption is usually adjustable, some manufacturers by simply lighting time rather than unknown customer usage to deceive consumers. As the solar street lamp manufacturers, the company solemnly promises here: we will absolutely guarantee product according to the demand of customers and the production, the good faith management!
