Q:Do you think it is expensive to install LED street lamp with WIFI function?
The cost will be much higher, and it will involve control and network problems.
Q:What are the parts of a LED street lamp?
The working principle and design of solar street lamp LED 2008 01 Friday 25 March 22:28 with the world energy crisis intensifies, countries are seeking a solution to the energy crisis, a road is used for new and renewable sources of energy; the other one is looking for new energy-saving technologies, reduce energy consumption, improve the utilization efficiency energy.
Q:The same brand of chip, how to judge the quality of LED lights?
Should pay attention to the cooling system for street lamp, street lamp cooling system is now divided into three types, one (die-casting aluminum (aluminum), two (three), Qi tablets) but also pay attention to the radiator is enough, there are many manufacturers have 90W heat lamps, used to install 120W to save the cost, so that his cooling system will follow no, my colleagues decay is relatively large
Q:LED street lights installed on both sides of the road, horizontal installation and angle installation (0~30 degrees), natural convection heat dissipation, that good heat dissipation.
Generally speaking, this is a better angle installation, and the light source installed vertically below is the best,In fluid mechanics, the density of hot air is smaller than that of cold air, small density, light mass of hot air rises, cold air sinks, and natural convection occurs. But it doesn't have to be angled, depending on the shape of your fin design and the way it is cooled.
Q:What is the difference between the brightness and illuminance of LED street lights and the brightness and illumination of ordinary high-pressure sodium lamps?
LED street is just such, light is relatively serious,
Q:How much is the LED terminal voltage of the solar street light controller v?
This depends on the situation, LED, the general is 5V
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's the difference between a solar street lamp and a street light complementary street lamp?
The working principle of the system is simple, the use of solar photovoltaic panels during the day the principle of solar radiation and into electrical energy output, through the charging and discharging controller is stored in the accumulator. When night illumination gradually reduced to about 10lux, Jin Zhan solar energy battery open circuit voltage of about 4.5V, the charge and discharge controller to detect the a voltage value of the battery discharge lamp action. After 8.5 hours battery discharge, the charging and discharging controller moves and the battery discharge is finished. The main function of the charge and discharge controller is to protect the battery.
Q:High frequency jet lamp, LED lamp, xenon lamp, which is suitable for street lamps
The so-called high frequency jet lamp, according to my observation, should be ceramic metal halide lamp, just ballast working mode and the previous adjustment, it may also be manufacturers just make a gimmick.To do street lights, the current high-pressure sodium lamp and LED lights are more, but if the local highways department can pass, it is recommended to adopt 150W or 250W ceramic metal halide lamp, but the quality of supporting ballast must be reliable.
Q:Why do street lights use bat wings to match the light curve?
The bat light curve of the street lamp is based on the light distribution of the common high-pressure sodium lamp. Now the LED street lamp is just imitating. The bat wing curve gives full use of light. LED light is straight scattered, not light, glare, uneven radiation and other issues.
