Advantages of LED Lighting
How do led lights work?LED (light emitting diode) is a kind of solid-state semiconductor device that can convert electric energy into visible light, which can directly convert electricity into light.LED can directly emit red, yellow, blue, green, green, orange, purple, and white light.
LED light source has the advantages of low-voltage power supply, low energy consumption, strong applicability, high stability, short response time, no pollution to the environment, multi-color luminescence, and so on.
Although the price is higher than the existing lighting equipment, it is still considered that it will inevitably replace the existing lighting devices.LED lights include working lights; led corn lights; led retrofit kits; dock lights; led balloon lights …What are the advantages of LED lights? Here are some of the most advantages:
1ïžEnergy Conservation:
One of the main advantages of LED lamps is that they produce higher lumens per watt than incandescent lamps and fluorescent tubes or bulbs. This means that they can produce the same amount of light at a lower energy input.Because of their high lumen output per watt, LEDs are capable of turning about 70% of their energy into light.Â
This makes them much more efficient than other bulbs, which waste a lot of energy by turning it into heat. LED is made of semiconductor materials to produce light-emitting diode, which directly converts electrical energy into light energy.
The basic working principle of the energy-saving lamp is the same as that of the fluorescent lamp. The ballast is changed into an electronic one and integrated with the lamp tube. Although it saves electricity than incandescent lamp, its conversion efficiency is lower than that of LED.
The energy consumption of white LED is only 1 / 10 of incandescent lamp and 1 / 4 of energy saving lamp.Generally, the luminous efficiency of Halogen Bulb is 15-20 lumens / watt; the luminous efficiency of Incandescent Light Bulb is 12-24 lumens / watt; the luminous efficiency of CFL bulbs is about 65 lumens / watt;now the luminous efficiency of LED Light Bulb is 100-155Â lumens / watt.Â
For example, to produce 500 lumens, a typical incandescent lamp needs 50 watts, while a fluorescent or energy-saving lamp requires 20 watts. However, led corn light or led retrofit kits take only 5 watts to produce 775 lumens. This advantage translates into cost savings in electricity charges.
2ïžLong Lifetime :
One of the biggest advantages of LED lights is long service life.LED lamp has a longer service life, up to 50000-100000 hours.. The life of LED lamp is determined by the light attenuation. Generally speaking, the longer the time is used, the greater the light attenuation, the dimmer the brightness of the lamp will be, until it finally does not light up and can not work normally.Â
There are two reasons for the light failure, one is the light failure of blue LED itself, the other is the light failure of phosphor. Different LED lamps have different light attenuation.How do led lights work? The light-emitting mechanism of light-emitting diode is determined by the special structure of the diode. Â Its special light-emitting mechanism determines that the light-emitting lifetime is as long as 50000-100000 hours.
The components of an LED and the way that they generate light significantly extend the lifespan of these bulbs. Where other bulbsâ lifespans are shortened through both proper and improper usage, the LED bulbâs low heat levels, durability, and energy efficiency make it possible for it to outlast other types of bulbs by thousands of hours.
Typically, the important parts of a light bulb, such as the filament, weaken over time, which causes the bulb to burn out. But LEDs donât burn out the same way that other bulbs do; instead, the amount of light they produce decreases gradually in what is called âlumen depreciationâ.Â
The lifetime of an LED bulb is based on how long it takes for the lumen output of the bulb to decrease to 30%, so it will likely last longer than the average rated lifetime hour listed on the box if you donât mind or donât notice the decreased illumination.
3ïžEnvironment protection
It is becoming increasingly important for companies to become eco-friendly. Customers increasingly want environmentally friendly options and using an environmentally friendly light source can help companies reduce their energy use, as well as attract a socially conscious consumer base.
Compared with the traditional light source, LED has better environmental protection benefits. There is no ultraviolet and infrared in the spectrum. The waste can be recycled, pollution-free and mercury free. It can be safely touched. It is a typical green lighting source.
LED lamps do not use high-risk mercury like fluorescent lamps, and there will be no public hazards such as mercury ions and phosphors that may leak during the manufacturing process or after the bulb is damaged. The epoxy resin used for manufacturing LED belongs to organic polymer compound.Â
After curing, it has good physical and chemical properties. It has high bonding strength to wafer and metal, hard and flexible, stable to saline alkali and most solvents, and is not easy to be damaged. Even if it is damaged or aged, it can be recycled and reused without causing pollution to the environment.Â
For the particle layout of ED lamps and displays, the light produced is generally scattered, and little light pollution is produced. Led working voltage is low, DC drive mode is adopted, ultra-low power consumption (single tube 0.03 ~ 0.06w), photoelectric power conversion is close to 100%, under the same lighting effect, more than 80% energy saving than traditional light source.
4ïžWidely Used:
LEDs offer a wider spectrum of correlated color temperatures (CCT) ranging from 1,000K to 10,000K as per the figure below while incandescent lighting generally ranges between 2,000K and 6,000K. You can read the youlumi lighting guide.
The CCT dictates the color of the light emitted with higher CCT values giving a brighter, cooler light. Lower CCT values are associated with a warmer, more yellow light. Therefore, depending on the desired use and application, it may be easier to find a perfect fit in an LED product lineup than an incandescent. Like working lights or dock lights normally make 5000K, balloon lights could be 6000K.

Application directions includeïž
Building exterior lighting: The LED light source is small and thin. The research and development of linear projection lamps undoubtedly become a highlight of LED projection lamps, because many buildings do not have a place to place traditional projection lamps. It is easy to install, can be installed in horizontal or vertical direction, better combined with the surface of the building, expanding the creative space.
Landscape lighting: unlike traditional lamps and lanterns, LED light source is mostly glass bubble shell. It can be organically combined with urban street furniture, and can be used for lighting in urban leisure space such as path, stairs, deck, waterfront and gardening. Â

Signs and indicative lighting: for example, road surface separation display, stair step local lighting, emergency exit indication lighting, led self luminous underground lamp with appropriate surface brightness or lamps embedded in vertical wall, ground guide light in theater auditorium or indicator light on the side of seat, and guide light on the floor of shopping center, etc.
 Indoor space display lighting: LED light source can be used as a substitute for optical fiber lighting in museum. Commercial lighting mostly uses color LED, indoor decorative white LED combined with interior decoration provides auxiliary lighting, hidden light band can use LED, especially for low space.
Entertainment places and stage lighting: due to the dynamic and digital control of LED color, brightness and dimming, the lively saturated color can create static and dynamic lighting effects. From white light to any color in the full spectrum, the use of LED opens a new way of thinking in this kind of space lighting.
Video screen: full color LED display screen is the most eye-catching outdoor large-scale display device in the world. It adopts advanced digital video processing technology, and has incomparable large area and ultra-high brightness.Â
In addition, the LED lights installed on the screen can also adopt various specifications of luminous pixels according to different indoor and outdoor environments to achieve different brightness, color and resolution to meet various purposes.
Vehicle indicator lighting: used for LED navigation information display of vehicle road traffic. In urban traffic, highway and other fields, led as a variable indicator and lighting function.
