Q:What are the components of a LED street lamp?
Like traditional street lamps, the lamp post and support arm are requiredThe lamp is different with the traditional lamp, the main components of a LED light source, lamp shell (radiator), power supply.I can provide the light source and the power module
Q:Constraints on LED street lights
Maintenance problem. High pressure sodium lamp is good for maintenance. As long as the lamp is scrubbed, it is not necessary to replace it. The light source is changed once every 4 years, which is very convenient. And LED street lamps, involving LED tubes, modules (including lenses, etc.), power devices, etc., components and components of the possibility of greater damage, maintenance difficulties, it is possible to replace the whole, higher costs. High price: LED street price is 2-5 times that of high pressure sodium lamp, even if the power consumption of LED lamp is only 1/2 HPS, but because the price is much higher than that of high pressure sodium lamp, high pressure sodium lamp is replaced by LED cost recovery cycle will still be very long;
Q:What's the main reason for LED street lights?
The quality of the LED itself is the main reason
Q:LED street lights around 2800K, the highest color temperature, how many lumens per watt?
The best lamp can do 140 lumens, but to do the whole lamp 120 is basically impossible, the restricting factors of power supply and the other is unable to achieve this level
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:Does the LED street lamp work well with a single light source or with integrated light sources?
Conditional words, of course, a single point is better, so that the light is not so obvious, and in tandem, bad 1, the whole string will not be bright
Q:What are the benefits of a modular LED street lamp?
The light is relatively homogeneous, the details of the consultation can also be a day of red lighting, a few years ago, the use of integrated light source more, now mostly use modular streetlights, cost-effective, flexible design, high brightness to a point just add a module to a low brightness reduction of a module, very convenient.
Q:What heat sink is best for LED street lamp radiator?
What is the external force of heat, force, that is to say, with the use of external heat, fan in the lamps or using superconducting tube, water-cooled, and so on, the advantage of active heat dissipation, efficiency has been improved, but the structure is complicated, the cost is increased, and the service life of the cooling equipment is generally not too long, less than 2 years is basically finished.
Q:Want to do a LED street lighting, do not know how to start, please recommend books or websites, can understand the whole process of doing LED street lights!
Sorry, can not say, now these things are sold hot goods, no one will change to you, including a lot of information
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
