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: in daily life the inside of the light, common led power driver is an ideal protection and control device, can offer high lamp is more stable and safe operation, which made the current and voltage values to meet operation requirements. Given that appeared on the market 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 simple to understand the basic characteristic of the light-emitting diode power drive. First, the high reliability of leds power drive. In short, a lot of led street lamp installed on high, and it hindered the maintenance and cleaning, not only the cost is very high, and there are various operation is not convenient. Therefore, the LED power driver reliability is very important. Secondly, high efficiency is one of the main characteristics of this 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 that more small power consumption, and then make light of lower heat value, make the light emitting diode, longer service life. 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, below the 70 watts of electrical 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. The first is the constant-current power supply of constant voltage source to multiple, the second is in series or parallel operation of light-emitting diodes (leds), namely method 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 basic protection function, the power also can prevent leds overheating, good to better accord with the related provisions on electromagnetic compatibility. A complete set of solar led street light should be from lampposts, lighting, photovoltaic panels ( Solar panels) , battery, controller and foundation of cage, wire and screws. By the light pole height, wall thickness, the influence of the cantilever length and molding process; The higher the height of the bar, bar the higher the price, and the wall thickness and length of cantilever is directly proportional to the price of the rod. In terms of shape, one is the most commonly used word arm, from the bent arm, conch and S boom, including the bent arm of a lower price, and higher prices of conch arm and arm S. At present, solar led street lamp used in the photovoltaic panels are divided into monocrystalline silicon solar panels and polycrystalline silicon solar panels, monocrystalline silicon solar photoelectric conversion rate is higher than polycrystalline silicon solar panels. Solar led streetlight ( jschindo。 com) Batteries are divided into gel battery and lithium battery. Under the same power, the price of lithium-ion batteries more than double the gel battery. In the case of low power, we recommend qualified customers choose lithium-ion batteries, because environmental protection, convenient, efficient and installation; In the case of high power, it is recommended that the gel battery, because of its high cost performance, maintenance and good stability. 。 。 。 。
