LED street light contrast the traditional advantage how to choose the constant current modules

LED street light is the main force of city road lighting, the comparative advantage of traditional street lamps, specifically what advantages does, we contrast list from several main aspects below LED street light compared to the traditional grid lamps of all kinds of advantages. one Illuminance contrast:.

LED street lamp is the main force of city road lighting, comparative advantage of traditional street lamps, specifically what advantages does, we contrast list from several main aspects below LED street light compared to the traditional grid lamps of all kinds of advantages. one Illuminance contrast:. Using 60 watts of the LED street lamp light can achieve high pressure sodium lamp 250 dig, use power greatly reduce, because LED street lamp, low power use, so can very good with wind and solar energy, can be used in time on the road of the city. two Safety performance:. In the current market on some of the electrodeless lamp, cold light etc are inspired by high pressure point X light illumination, contains a lot of harmful metals such as mercury, and the harmful rays, because compared to the LED street light is a safe low voltage products, so at the time of use and installation can significantly reduce the risk of a security risk. 3. Compare the environmental performance:. Street lights are commonly contains some harmful metals, contains the many harmful rays in the spectrum, street lamp manufacturers compared to the LED street light spectrum pure green, do not contain red, uv, etc. , no radiation, there will be no more production of light pollution, and do not contain harmful metals, waste can be recycled, is a typical green lighting products. Four. Contrast: of quality and service life. General service life of the lamp is 12000 hours, not only the lamp replacement cost is high, and it would be easy to affect the traffic, especially in places such as tunnel construction is more inconvenience, comparison of LED street lamp, its life expectancy is 100000 hours, according to 10 hours a day usage calculation, but also can be used for ten years, cost performance is high, in addition, the LED street lamp, shockproof, waterproof, impact resistance and so on are all excellent, product warranty period are free maintenance. Five. LED lights, electricity bills. Our jin hui 60 w LED street lamp of electricity within a year, is only the ordinary 250 w high pressure sodium lamps a year 20% of the electricity, can greatly reduce the spending, if the customer choose the solar LED street lamp, then produce lamps manufacturer of electricity is equal to 0. We know all the LED constant current source power supply must be used, but at present many street lamp manufacturers are mostly in the case of LED module has been designed to find the right again constant current module, but this kind of problems encountered by the design method is, LED street lamp, at least make this design is not the best, may still need to redesign the LED module. Often ask, constant current drive module can take how much power, this kind of question is actually unable to answer, because of the constant current module can take how much power is related to many factors, from constant current module itself, it mainly and cooling requirements and cooling conditions, of course, and drive chip current driving ability, even though these are settled, however, however, a constant current module driving power, besides thermal capacity and its related major is related to its working efficiency, and its working efficiency and many external factors, especially the user usage, so in the design or choose the LED module is going to take an examination of street lamp manufacturers about requirements and characteristics of constant current source. The biggest characteristic of solar LED street light is that it is usually by the battery power supply, and there were some characteristic is needs to consider: the battery. 3. 1 only several provisions of the voltage, battery 12 v is the most commonly used, because it is the standard voltage of battery, 24 v you need to use two series, 36 v is even more rare, therefore, often need to use booster in solar LED street lamp type constant current driver module, this will affect the efficiency of constant current module. 3. 2 in the solar street light another issue to consider is the change of the input voltage. For constant current source output power and efficiency, in order to get the highest efficiency to keep the ratio of input and output voltage is close to 1, the better, but if the input voltage instability, so it is hard to remain at the highest efficiency of the best, solar LED street lamp system usually adopts the storage battery as energy storage unit, and in just charged battery and fast after electric voltage when there will be a bigger change, usually this kind of change was over 30%.
