Street lights led street lamp

Led street lamp manufacturers technology sharing: daily life of common high lamp inside the led power driver is a kind of ideal protection control device, it can provide more stable for light, safe work operation, thus makes the current, voltage and so on all conform to run


the led street lamp manufacturers technology sharing: light, the built-in led power driver is common in daily life, a kind of ideal protection and control device, can offer high lamp is more stable and safe operation, so that the current and voltage values to meet operation requirements. According to the market on the many different brands of leds power drive, what are the basic characteristics of the drive equipment? It is estimated that most of the users of the LED power driver not understanding, so in the process of buying and operating the error prone. Let's take a look at the basic characteristic of the light-emitting diode power drive. First of all, the high reliability of leds power drive. In short, a lot of led street lamp installed on high, and interferes with the maintenance and cleaning. It is not only expensive, but also not convenient operation. Therefore, the reliability of the leds power drive is very important. Second, the high efficiency is one of the main characteristics of this kind of device, because the light emitting diode is a kind of high-tech energy-saving products, so the efficiency of the power drive must be very high, so as to reduce power consumption, and lamps and lanterns of calorific value is lower, makes the use of light-emitting diodes (leds) live longer. Third, is a basic characteristic of high power factor, because the power is the basic requirements of power grid to the load. Under normal circumstances, a 70 - watt electrical products under no mandatory index requirements. Fourth, light emitting diode drive power drive mode is also a major feature. Now, different models have different driving mode, mainly divides into two kinds of different patterns. First of all, a constant voltage source and then to multiple constant current source power supply. Second, the leds in series or parallel, it is a way of dc constant current power supply. Fifth, a variety of protection function is one of the biggest characteristic of this drive. In short, in addition to the protection of the basic functions, the power supply can also prevent light-emitting diode temperature is too high, make it more in line with the relevant provisions of electromagnetic compatibility. A complete set of solar led street lamp should include: lamp, light source, the photovoltaic panels ( Solar panels) , battery, controller, basis of cage, wire and screws. The lamp height, wall thickness, the influence of the cantilever length and molding process; The higher the height of the light pole, the higher the price of the light pole, and the wall thickness and length of cantilever is directly proportional to the price of the light pole. In terms of modelling, the most commonly used is the body's arm, from the bent arm, conch and S boom, including the bent arm of the relatively low price, the price of the conch and S boom is relatively high. At present, the photovoltaic panels for solar led street lamp is divided into monocrystalline silicon solar panels and polycrystalline silicon solar panels. Monocrystalline silicon solar panels photoelectric conversion rate is higher than polycrystalline silicon solar panels. Solar led streetlight ( jschindo。 com) Batteries are divided into colloidal battery and lithium battery. Under the condition of the same power, the price of lithium battery is more than twice as likely to colloidal battery. In the case of low power consumption, we recommend the qualified customers choose lithium battery, because it is environmental protection, convenient, efficient, easy to install. Under the condition of high power, high performance/price ratio, and because the gel battery, maintain stability is good, recommended to choose gel battery. 。 。 。 。 。
