Introduce the Advantages and Disadvantages of LED Street Lamps

  Author :Green earth– LED Strip Lights manufacturers

First, the advantages of the LED street lamp:

1, its own characteristics——The one-way, no light diffuse, ensures the light power;

2, the street lamp has a common secondary optical plan, and the light of the LED street base is taken to the desired lighting area, further improves the light power to reach the throttle;

3, LED's source power is now 90-110LM / W, and there is still a large space, the theoretical value of 250Lm / W.

The light-emitting power of high pressure soda lamp is added as the power is added. Therefore, the overall light effect LED street lamp is strong than high pressure sodium lamps; (this overall light effect is theoretically, the light effect of 250W above high pressure sodium lamp is higher than LED " .

4, LED street lamps are light color resistance than high pressure sodium lamps, high pressure sodium lamp color syndrome is as long as 23 or so, while the LED street lamp color syndrome reaches 75, from visual mentally thinking.

When the equality brightness is reached, the lighting level of the LED street base can be even more than 20% lower than the high pressure sodium lamp, and according to the English truth lighting specification;

5, the LED street base is less than 3%, and the light loss is less than 3%. It is still reached the road to use illuminance requirements for 10 years, and the high pressure sodium light is decreased, and there is more than 30% of the year.

6, LED is a low-voltage device, driving a single LED voltage is a safety voltage, and a single LED power in the series is 1 tile.

So it is a power supply that is more secure than using high voltage power supplies, especially for public places (for example: street lamps, factory mine lighting, car lighting, civil lighting, etc.)

7, long life: 50,000 hours can be used, and the shortcomings is that the number of power supplies is not ensured.

Second, the shortcoming of LED street lamps:

1. Single LED power is low. In order to obtain high power, multiple parallel use are required.

2. Spots. Because the shortcomings of white LED self-production process plus a cooperation with reflection cups or lenses, it is easy to form a yellow circle”question.

3. Heat dissipation. The street lamp is a problem with high-power LED light source. The high power LED is difficult to handle, and the brightness after overheating will be significantly reduced, the light is severe, so the power cannot be done too much.

About the Related Introduction of Ceiling Lights
  Author :Green earth– LED Strip Lights manufacturersThe lamp manufacturer produced with a lot of kinds, can bring us great convenience when using it, let's take a look at the related introduction of ceiling lights.First of all, it is characterized, there are many types commonly used in ceiling lamps, including square cover ceiling lights, pointed round ceiling lamps, etc., it can be directly installed on the ceiling, and it is easy to install, simple in style, very good in space lighting. Effect. I know its characteristics, the rest is the problem. The inside of the ceiling lamp generally has a ballast and loop tube, which can instantaneously start, and extend the life of the lamp and the power consumption is also low. The ceiling lamp has remote control and no remote control. It can be selected according to our needs.Introduction to the ceiling lamp, Xiaobian will introduce you to you, we can choose itself when using itself.
