As people's understanding of light gradually deepens, we find that fluorescent lamps have their irreparable defects:
1.flicker
The flicker is generated by the use of alternating current in fluorescent lamps, and a short, imperceptible flicker occurs when the current is commutated. The frequency of occurrence is twice the frequency of alternating current, that is, 100 Hz. The light is suddenly dimmed, and suddenly bright makes the ciliary muscles contract and relax to adapt to the environment. Continuous and intense exercise for a long time makes the ciliary muscle fatigue, and the eyes appear sore and painful.
2. Infrasound
The fluorescent lamp ballast will oscillate internally and emit infrasound waves when it is working. Infrasound is a band that humans cannot perceive. Long-term exposure to infrasound radiation can interfere with people's nerves, causing people to have symptoms such as dizziness, nausea and even depression.
3. Mercury pollution
Mercury, as a necessary intermediate for phosphors to emit light, is commonly found in fluorescent lamps. Working for a long time will increase the temperature of the fluorescent lamp and escape of mercury vapor. Mercury not only causes huge irreversible pollution to soil and water, but also affects human health. Mercury, as a kind of heavy metal, can cause chronic mercury poisoning. The clinical symptoms are dizziness, forgetfulness, and even slight tremor in severe cases.
4. Blu-ray
The color forming principle of fluorescent lamps is that electrons excite phosphors of three colors to emit light. Blue light is one of the three colors. Due to this characteristic of fluorescent lamps, the result of uneven spectral distribution. Among them, the intensity of blue light, red light and green light each account for one-third, resulting in excessively high blue light intensity compared to general light sources.
Blue light is the wave with the highest energy in visible light. Its energy can penetrate the cornea and lens and directly harm the retina. Long-term exposure to blue light can cause dry eyes, tearing, and even macular disease, which can lead to decreased vision.
5. Short life and high energy consumption.
The service life of a fluorescent lamp is generally 3000 hours, and a large amount of heat is generated during operation, so it consumes a lot of electricity.
While Led Lighting has the incomparable advantages of fluorescent lamps:
1. Long life
Compared with the life of ordinary fluorescent lamps, the life of LED lamps is much longer. The average service life of fluorescent lamps is about three thousand hours. The average life span of led lighting is 50,000 hours. Depending on how you use it, its service life may be as long as 100,000 hours. This means that LED lights can be used for 6 to 12 years before you need to replace them. This is 17 times more than fluorescent lamps.
2. High energy efficiency
Another leading advantage of LED lighting is its energy-saving operation. You can use useful lumens to measure the energy efficiency of a light source, which describes the amount of light emitted by the device for each unit of power or watt used by the lamp. In the past, we measured light by how many lumens it produces, but the reality is that some of these lumens are wasted. Compared with other Lighting Technologies, LED lighting produces less waste light and more useful lumens.
These energy efficiency improvements are directly related to financial savings. When you replace traditional light sources with LED light sources, your energy consumption will plummet. Therefore, manufacturing LED lights is a wise investment for any company's bottom line!
3. Environmental protection
It is becoming more and more important for companies to become more environmentally friendly. Customers increasingly want environmentally friendly options. Using environmentally friendly light sources can help companies reduce energy use and attract socially conscious consumer groups.
The environmental benefits of LED lighting also extend to its manufacturing process. Many traditional lighting sources, such as fluorescent lamps and mercury vapor lamps, use mercury internally as part of their structure. Therefore, when they reach the end of their service life, special treatment is required. You don't need to worry about any of these problems with LED lights.
4. Ability to operate in cold conditions
Traditional light sources do not like cold weather. When the temperature drops, light sources, especially fluorescent lamps, require a higher voltage to start, and their light intensity will decrease.
On the other hand, LED lights perform about 5% better in cold temperatures. This is why LED lights are a better choice for the lighting required for freezers, meat storage cabinets, cold storage spaces or refrigerated display cases. Their ability to work so efficiently in cold weather also makes them a perfect choice for parking lot lights, lights for illuminating the perimeter of buildings, and lights for outdoor signage.
5. No heat or ultraviolet radiation
If you have ever tried to replace a fluorescent lamp immediately after it goes out, you will know how hot they are during use. Many traditional lighting sources use more than 90% of the energy for heating, and only allocate 10% of the energy to the actual light generation.
LEDs emit almost no heat, and most of the light they emit is in the visible spectrum. This feature is one reason why medical experts see LEDs as a possible solution to seasonal affective disorder (SAD), which affects many people during the darker months of the year.
It also makes LEDs ideal for lighting artworks, which degrade or decompose over time as they are exposed to ultraviolet light.
6. Instant lighting and the ability to withstand frequent switching
If you are looking for a light that needs to light up quickly, choose LED lighting. The LED lights can be turned on and off immediately. For example, if you are using a metal halide lamp, you need to prepare for the warm-up period. Think about how it flickers when you turn on a fluorescent light, and it usually takes two to three seconds to fully light up. These are some complications that can be avoided by installing LED lights.
In addition, if you frequently turn on and off traditional light sources, their lifespan will be shorter. LED lights are not affected by frequent switching. It will not cause any reduction in its lifespan or efficiency.
If you need to restore the lights immediately after a power outage or power surge, this feature makes LED an ideal solution for your business. This feature is also useful if you want your lights to light up immediately when employees turn on the building before the sun rises early in the morning.
Since LEDs are not affected by switches, they can be quickly cycled for flashing light displays or applications that require sensors to switch frequently.
7. Dimming ability
LEDs perform well at almost any power percentage, from about 5% to 100%. Some light sources (such as metal halides) are less efficient when dimmed. Sometimes, you can't dim them at all.
The situation with LED lighting is just the opposite. When you use a power supply lower than full power on the LED light, its operating efficiency will be higher. This feature also brings other benefits. It extends the life of the bulb, which means you use less energy, thereby reducing energy costs.
It should be noted that when using LEDs, you cannot use traditional equipment to dim the lights. They need hardware specific to their technology.
8. Directionality
Every traditional Lighting Technology emits light 360° around the light source. This means that if you want light to illuminate a specific area, you need to purchase accessories to direct or deflect the light in the desired direction.
If you do not use something to reflect or redirect light, you will waste energy lighting areas that do not need to be illuminated, which will result in higher energy costs.
However, LED lights can only illuminate an area of 180°. When you need recessed lighting in industrial kitchens, corridors or bathrooms, this makes LED lighting the perfect choice. It is also an ideal choice for lighting artwork, not only because it will not reduce the quality of the artwork, but also because you will not lose any lighting power on the back of the light source.
Whether you want to improve energy efficiency, simplify maintenance or improve environmental performance through lighting technology, LED lighting is your solution. Although the cost of LED lights is indeed higher than that of traditional lighting sources, these costs are declining year by year. Even if you have to pay more upfront costs, in the long run, the money you save will be enough to make up for the higher upfront costs.
