Why are LED floodlights energy-saving and environmentally friendly?

In today's society, lighting is an indispensable part. In the current social background, energy saving and environmental protection are an indispensable part of the lighting field. In the past, high-pressure sodium lamps made important contributions to large-area outdoor lighting, but high-pressure sodium lamps are still It has the disadvantages of high energy consumption and poor environmental protection (containing harmful substances such as mercury). With the rise of LED lamps, they are increasingly used in lighting areas in various places (sports floodlights, marine floodlights, parking Field lighting, etc.), and LED floodlights use semiconductor technology, which has a high efficiency in converting electrical energy into light energy and does not contain harmful substances such as mercury, making it very suitable for environmental protection themes.

 

1. The power of LED floodlights is low, only about 1/4 of high-pressure sodium lamps. This shows that under the same brightness, the LED floodlight flux is almost the same as the 500W high-pressure sodium light flux, but the energy consumption can be reduced by 75%. around, which can significantly reduce energy consumption.

2.LED floodlights use semiconductor technology so they do not contain harmful substances such as mercury. In contrast, mercury in high-pressure sodium lamps is a harmful substance that can pollute the environment. Therefore, using LED floodlights can reduce the negative impact on the environment. Moreover, the LED floodlight uses solid mercury, which will not cause pollution to the surrounding air even if it is broken. It has a recyclability rate of over 99% and is an environmentally friendly green light source. This is in line with the concept of sustainable development and is conducive to protecting the global environment.

Are LED drivers AC or DC?

LEDs need a dependable power source in order to function. This power is supplied by LED drivers, which convert alternating current (AC) to direct current (DC). By adjusting for variations in the temperature and electrical conductivity of the LEDs, they provide a consistent and continuous power supply.

There are two types of LED drivers: Constant Current LED drivers and Constant Voltage LED drivers.

LED power sources that provide a “constant-current” output have typically been referred to as LED drivers. In the past, AC-DC power supplies that provided a regulated “constant-voltage” to LEDs were referred to as LED power supplies. Today, the terms “LED driver” and “LED power supply” are used interchangeably.

In certain cases, a malfunction of the LED driver could be attributed to extreme high-temperature factors, as operating at elevated temperatures can lead to component damage due to heat accumulation. In other instances, damage to the LED driver might result from voltage instability in the power grid or surges caused by lightning strikes. Furthermore, when the output voltage and current of the LED driver do not match the electrical parameters of the LED chips, the LEDs may fail to operate properly, leading us to suspect a malfunction in the LED driver.

Flickering is one of the most common indicators of a faulty LED driver. Additionally, a change in the brightness or dimness of the lights also signifies a defective LED driver. Finally, if LED lamps do not work at all, it could also suggest a problem with the LED driver, SPD, or the LEDs being broken.
