Q:Constraints on LED street lights: The development of the domestic LED light source relative to foreign technology started late, from the international leading industry there is a certain distance, although the domestic LED light source theory of life can reach 100 thousand hours, but because of the heat problem cannot be solved completely and effectively, so that the actual life of large discount; unstable power supply system: LED driver power supply is the industry consensus in fact it is not stable, on the LED lighting industry back, because the driving power supply is an important part of the LED street lamp, which will lead to failure of the whole lamp fault. Due to poor reliability of power installed street lights are likely in a short period of time will be bad, the LED street lamp this outdoor height device, difficult installation, maintenance more difficult, for the lamp manufacturers, power supply instability makes the rising cost of maintenance.

Q:How to determine the power of LED street light?: It is difficult to determine the power of the LED street lights used on a particular section of the road, but it can be estimated from the street lights seen

Q:What are the characteristics of the development of LED street lamp intelligence?: The traditional LED street lighting system is through the switch on lights and adjust, intelligent system is based on the user terminal module under the instruction and transmits the signal to the control center software through the electronic induction, with controller circuit voltage and current amplitude, so as to control the remote single lamp or lamp switch, dimming, monitoring etc..

Q:Can the LED power supply be used as street light power supply?: Pay attention to 2 aspects:Relevant parameters should be met! Such as power, voltage, current, etc.Street lighting power should be waterproof, anti lightning and grounding.

Q:What is the reason for the low power factor of LED street lamp?: General LED is the switching power supply to drive, the switching power supply improve power factor method is to increase the power factor correction circuit, power factor correction circuit is generally more than 50W in order to play a role.

Q:How can a LED street lamp protect against lightning strikes?: Generally, the LED street lamps are all conductor materials, and they are equivalent to a lightning rod. Therefore, the power supply of the street lamp must be installed on the lead wire and the ground net. These systems constitute an external lightning protection system. Such a system can avoid fire accidents and personal safety accidents caused by direct lightning in LED street lamps. The interior lightning protection system of street lamp refers to the protection of the equipment in the street lamp through grounding, setting voltage protection, etc.. The internal system prevents incoming lightning and other forms of over-voltage intrusion, resulting in power damage, which is not guaranteed by external lightning protection systems.

Q:What is the active power of LED street lamp? What is the relationship between input voltage and current and power?: When the alternating current through the load resistor, and the resistance of the AC voltage and AC current through the resistor is the same phase, and between them the phase angle phi = 0 degrees, while the active power consumption in the resistive load, power grid to supply energy. When the alternating current through the pure inductance load, phase AC voltage on the advanced phase of current 90 degrees and the angle between them phi = 90 DEG, produce reactive power in inductive load, power supply of electric energy in the inductor for temporary storage and magnetic energy back to the grid into electricity such a periodic cycle, results for grid is not energy, so that the "reactive power", but "reactive power" and "reactive current" still exist. When alternating current through pure capacitance load, also similar to this, but the phase AC voltage on the lag phase of current 90 degrees and the angle between them phi = - 90 degrees.

Q:What is the role of heat phase change material on a LED street light?: I think that a product is not only from raw material to it, but also from the process of enterprises to work on each detail can be improved, with innovative thinking to consider the product of each process! Closely grasp the quality, seize the service. Treat the product, you want to treat their children, in order to make the product to perfection!

Q:LED street lamp or solar street lamp?: Compared with traditional lighting, the initial investment of LED is more expensive, but its light source life is 4-5 times as much as that of ordinary light tube. Low power consumption. The release of ultraviolet light, the night will not attract mosquitoes.

Q:22 km road, every 33 meters to install a street lamp, street light power 120W, attached to the LED display 60W, a total of 180W, seeking the best laying line program: If there are 20 or so parallel units. Each unit of parallel =0.18x30=5.4KW, 6mm - 10mm - copper or aluminum wire. Light controlled single-phase AC contactor 50A.
