Q:What are the main uses of LED street lamps?
The main application of LED street, main roads, secondary roads and branches, factories, schools, gardens, city square, Garden Road lighting.
Q:What is the reason that the longer the wire pulls on the LED street lamp, the lower the voltage?
Resistance will block the passage of electricity; the greater the resistance, the greater the loss of electrical energy in the line.
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:Do ballast ballasts need to be used for starting the LED street lamp?
LED requirements are constant current power supply, some can also use switching power supply, but the cost is relatively high
Q:For the LED street light distribution, is it better to use a lens or a reflector?
Lens better point: the lens can be arbitrarily better match light, mold work is better than using reflective glass, the price of natural cheap
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!
You want to make street lights, that is easy and not easy, simple and simple, in fact, you want to see the manufacturer's demo assembly process on the Internet is impossible, because it relates to the confidentiality of the company. To see, you can go to the manufacturers to see, contact manufacturers business on it.
Q:Technical requirements for LED street lamps
The average illuminance of illumination uniformity (uniformityof, road, surfaceilluminance) is 0.48, and the spot ratio is 1:2.5. accord with road illuminance. The actual 1/2 center spot reaches 25LUX, and the 1/4 center light intensity reaches 15LUX, the minimum light intensity is 4LUX at 16 meters, and the overlap light intensity is about 6LUX.6., it has a very good application prospect in the new city lighting. Dimming for depth, and colors and other features are not subject to dimming.7. meet the humidity: less than 95.
Q:LED street light dedicated drive power 98W14 string 7, and ask 14 string 7, and what does that mean?
Or the 7 LED are connected in parallel to calculate a set, and then there are 14 groups of positive and negative electrodes, the negative electrode connected to the positive pole, and the 14 group is connected in series. This is also the 14 string of 7, and...
Q:What is the principle of constant current power supply in LED street lamps?
The source of power source rectifier lamp mainly alternating current, and the electronic components are basically.Made in direct current. So the input power must be rectified first.Diode zener diodes and Schottky diodes are common in power management systems.Many small power components operate at low voltages or require reference electricity in the systemVoltage will use a zener diode; in the switching power supply, the final low voltage DC output
Q:What are the ways to save energy in street lamps?
The power consumption of street lighting also weakens the effect of landscape lighting on both sides of the road. Therefore, in accordance with the provisions in the design of "lighting design standard" City Road in luminance, uniformity of illuminance and combining the actual situation of site design, reasonable selection of light source, so as to meet the needs of the road and can meet the demand of average illumination, surface illumination uniformity requirements, maximize the utilization coefficient of lamps, in order to save the purpose of energy.
