How long will the led shoebox light last?

There are many types of exterior lighting, one of which is very common in parking lots, parking spaces, driveways, and sidewalks, and even seen in outdoor sports grounds. It is called parking lot lighting. Shoebox lights for parking lot are the most common parking lot lights. The old parking lot lights have a rectangular shape and a right-angled structural box. This reminds us of shoe boxes. This is why most people call this type of parking lot lights "shoebox lights". The old traditional shoebox parking lot lights consist of high-intensity discharge lamps, such as metal halide, high-pressure sodium or mercury vapor lamps.

This passage is going to talk about the followings of shoebox lights:

  • Why is shoebox light having a longer life than other lights?

  • Why my LED lights are getting dim?

  • How long will the LED shoebox light last?


(1) Why is shoebox light having a longer life than other lights?

With the invention of LED (Light Emitting Diode) in 1962 and subsequent technological improvements, LED shoebox parking lot lights are currently available. Compared with fluorescent lamps that can only convert 5%, LED lamps have 80% higher energy efficiency than traditional old fluorescent or incandescent lamps. 95% of the energy is converted into light inside the LED, and only 5% of the energy is converted into heat. They accept the energy of light. LED lamps consume much less power than old traditional lighting lamps. LEDs only need to consume 10% of the energy normally required by incandescent lamps. The service life of LED lamps is longer than that of traditional lighting lamps, and the service life of LEDs is 6 times longer than other traditional lamps, thereby reducing continuous replacement and overall manufacturing and transportation costs.


(2) Why my LED lights are getting dim?

It is a very common phenomenon that LED lights become darker as they are used. The light decay of LED lamp products is the weakening of the light signal during transmission. At this stage, LED products made by major global LED manufacturers have different degrees of light decay. High-power LEDs also have luminous decay, which is directly related to temperature. It is determined by the chip, phosphor and packaging technology. At present, the light decay of white LEDs on the market is one of the most important issues in the advancement of civil lighting. Light decay generally refers to its luminous flux. When the surface of the photosensitive drum is charged, as the charge accumulates on the surface of the photosensitive drum, the potential continues to rise, and finally reaches the "saturation" potential, which is the highest potential. The surface potential will decrease over time. Generally, the working potential is lower than this potential. This process of natural decrease in potential over time is called the "dark decay" process. When the photosensitive drum is scanned and exposed, the dark area (referring to the surface of the photoconductor not irradiated by light) is still in the dark decay process; the bright area (referring to the surface of the photoconductor of the part irradiated by light) the carrier density in the photoconductive layer increases rapidly. The conductivity rises rapidly, forming a photoconductor voltage, the charge disappears quickly, and the surface potential of the photoconductor also drops rapidly. Call it "light decay"..

Ordinary led lights are generally no problem with 3-5 years. The theoretical life of led lights is 100000 hours. According to the theoretical life, it can be used for 11 years. But this is the highest value in an ideal state, which is impossible to achieve in normal use. In real life, the service life of LEDs is also related to current, brightness, materials, and so on. Shoebox lights can last longer.
