LED Street Lamp Analysis LED Can Be Integrated Into Electronic Control System

The efficiency of LED is improved rapidly in the image below. The latest experimental data show that the efficacy exceeds 250 lm/W. However, in the actual lighting fixture, we must consider the control gear performance, the light flux depreciation, the temperature increase, the optical loss and other factors, so as to reduce the overall system performance.

The efficacy of various light sources increases over time.

Ii) unlike other light sources, leds do not "burn out". They only slowly lose light output over a period of time. This factor is important in determining the life of the LED. Life can vary according to operating conditions (temperature, humidity), current and type of LED.

Iii) environmental impact

Using leds can reduce the impact on the environment in several ways. Longer bulb life means less resources to maintain. They also do not use mercury and less phosphorus than fluorescent substitutes. These facts combine to make leds a smart choice and reduce the natural footprint.

Iv) controllability

LED can be integrated into the electronic control system, which allows the color balance and intensity to be independently controlled while maintaining the color accuracy. The traditional light source is impossible. For general lighting, leds have the ability to dim from 0.1% to 100%.


The LED is very strong. They do not contain filaments or fragile glass bulbs that may be damaged by mechanical vibration and impact. LED lamps are especially suitable for bridge, industrial area or gymnasium, etc.

A typical example of a region with high fracture probability. Low temperature running low temperature is a challenge to fluorescent lamps. At low temperature, the activation of fluorescent lamps requires a higher voltage and less flux. In contrast, LED performance inherently increases at low working temperatures. This function is a precursor to grocery stores, cold storage and outdoor leds.

No ultraviolet radiation

LED with negligible UV (UV) and minimal infrared radiation. LED has less radiation, making it suitable for heat-sensitive products. The lack of ultraviolet radiation (with the proper design of the optical components) makes them attractive, too, can also be used to illuminate such as works of art and ultraviolet degradation material such as microscopic objects
