The role of LED lighting is illustrated by example

LED fluorescent lamps are energy-efficient.

This product adopts the latest LED light source technology, saving up to 70% of electricity (the annual savings in electricity costs and related maintenance and repair costs are greater than the investment in purchasing this lamp), and the 12W LED fluorescent light is equivalent to 40W energy-saving lamps (the real power consumption of 40W energy-saving lamps is 41W to 43W, because of the ballast). The life of this lamp is more than 10 times that of ordinary lamps, and it is almost maintenance-free, and there is no problem of returning lamps, ballasts and brighteners frequently. The green and environmentally friendly semiconductor light source, with soft light and pure spectrum, is conducive to people's vision protection and physical health.

The 6000K cold light source gives people a visual cool feeling, coupled with the illumination difference design in the work or working position, which is more conducive to concentration and efficiency.

LEDs, as the third generation of body lighting sources, have a lot of fantastic advantages:

1) High light efficiency: The spectrum is almost entirely concentrated in the visible light frequency, and the efficiency can reach 80%-90%. The visible light efficiency of incandescent lamps with similar light efficiency is only 10%-20%;

2) High light quality: because there is no ultraviolet and infrared rays in the spectrum, there is no heat and no radiation, which is a typical green lighting source;

3) Low energy consumption: the power of the monomer is generally in the same brightness, and the power consumption is only 1 8-10 of the ordinary incandescent lamp under the same brightness

4) Long life: the standard life of luminous flux attenuation to 70% is 100,000 hours;

5) Reliable and durable: there is no tungsten wire, glass shell and other parts that are easily damaged, the abnormal scrap rate is very small, and the maintenance cost is extremely low;

6) Flexible application: small size, can be flat packaged, easy to develop into thin and short products to make point, line, surface, various forms of products;

7) Safety: The unit working voltage is roughly between, and the working current is between 20-70mA;

8) Green and environmental protection: waste can be **, no pollution, not containing mercury like fluorescent lamps;

9) Short response time: Adapt to frequent switching and high-frequency operation.

1. Large, medium and small LED displays: indoor and outdoor billboards, stadium scoreboards, information displays, etc.

2. Traffic lights: traffic lights, highways, railways and airport signals in major and medium-sized cities across the country.

3. Light and color lighting: outdoor landscape lighting and indoor decoration lighting.

4. Special general lighting: portable lighting (flashlight, headlamp), low-illumination lighting (corridor lamp, door lamp, court lamp), reading lighting (reading lamp for airplanes, trains, automobiles), microscope lamp, camera flash, desk lamp, street lamp.

5. Safety lighting: miner's lamp, explosion-proof lamp, emergency lamp, safety indicator lamp.

6. Special lighting: military lighting (no infrared radiation), medical surgical lights (no thermal radiation), medical lamps, special lighting for crops and flowers.

LED lights, all the same is green, energy-saving and environmentally friendly, frequent switching has no effect on the lights

Energy saving, power saving, beautiful and long life.

To a certain extent, the construction of urban lighting projects has brought more and more economic benefits to the country and individuals. In large, medium and small cities, whether it is a first-class project or a commercial individual lighting project, the effect of the urban lighting project has been significantly improved, and the urban lighting project has improved the quality of the city's night scene, making the city have a strong sense of the times.

The street becomes spectacular, the business opportunities of the commercial street are promoted, the night commercial activities are not limited by the light, the citizens are happy to buy their favorite goods in the bright commercial street, and tourists will also come to pull economic benefits, increase the sales of shops, increase the income of merchants, and naturally the amount of tax will also increase, and improve the economic income of the city.

The characteristics and functions of the lamp are described as follows:

Electric lamps are artificial lighting appliances that use electricity as an energy source, and electric lights convert electrical energy into light energy to illuminate human beings at night or in dark rooms.

Electric lamp is to convert electrical energy into light energy, to provide lighting equipment, its working principle is: electric current through the filament (tungsten filament, melting point of more than 3000) when the heat is generated, the spiral filament continues to gather heat, so that the temperature of the filament up to more than 2000, the filament in the incandescent state, like the red-hot iron can shine and emit light.

The higher the temperature of the filament, the brighter the light emitted. Therefore, it is called incandescent lamp. From the perspective of energy conversion, when the lamp emits light, a large amount of electrical energy will be converted into heat energy, and only a very small part can be converted into useful light energy.

Tungsten filament can remain stable at a very high temperature without melting, but directly sublimated into gas, and when the lamp is turned off, the temperature drops, and tungsten gas is re-condensed into a solid covered on the inner wall of the bulb, because tungsten is a black solid, so after the incandescent lamp is used for a long time, tungsten repeatedly accumulates on the inner wall of the lamp, and the bulb will turn black.

Electric lamps have a lifespan, generally after blackening, the life is not long, the black bulb will affect the quality of lighting, and it is not beautiful, so it is better to replace the black bulb as soon as possible with too long time, especially in a conspicuous position, the place that needs good lighting should be replaced as soon as possible, so as not to suddenly break the bulb without a spare bulb, affecting the normal lighting and life, causing various inconveniences.

The life of the lamp is related to the temperature of the filament, because the higher the temperature, the easier it is for the filament to sublimate (tungsten directly becomes tungsten gas), when the tungsten filament is sublimated to a relatively thin and thin one, it is easy to burn out after being energized, thus ending the life of the lamp. Therefore, the greater the power (wattage) of the lamp, the shorter the lifespan.

Home lighting: lighting and beautifying the home, including table lamps, wall lamps, chandeliers and ceiling lamps.

Floodlights: outdoor lighting, architectural and landscaping, mostly metal halide lamps in various colors.

Searchlight: Long-distance flood light for lighting, anti-theft and air defense.

Machine tool work light: lamps and lanterns used for machine tool equipment lighting, multi-section light poles or hose light poles are convenient to adjust the lighting direction, generally 36V power supply.

Stage light: used for stage lighting and stage effects, with various functions such as light chasing, flashing, dimming, color change, etc.

Explosion-proof lamp: used in industrial and mining and other occasions where combustible gas or dust is required.

Alarm light: A lamp with audible and visual display that is used to indicate a fault or danger.

And so on---

LED lights are now very common to use, many table lamps we buy from the Internet, many tube lights, basically LED lights, its own life is at least three times longer than ordinary incandescent lamps,Then in terms of energy saving, you can save at least 80% of electricity, and only a small amount of electricity and current is needed to burst out of strong light. <>

The table lamp we bought from the Internet is dozens of dollars apiece, this kind of battery can last for several hours, this can be charged, you can also choose to keep plugged in the electricity, this kind of lamp he uses LED lamp beads, which itself does not consume much power. If it is said that it consumes as much power as an incandescent lamp, the small battery contained in a desk lamp cannot be stored for a long timeBecause LED lamps are very energy-efficient, they save at least 80% of the electricity compared to the incandescent lamps we use in our homes. <>

The LED lamp itself also has a longer life, because it uses epoxy resin for sealing, which avoids the contact of external oxygen during the sealing process, and the stability of the lamp bead position can be ensured during this sealing process. It avoids the change of the position of the bulb caused by shaking and the situation of opening the welding light box. LED bulbs rarely burn bulbs, and the incandescent lamps at home may burn when used, but the LED bulbs will not burn almost non-existentIf there is a problem in this case, it is generally a problem with the connection between the circuit and the circuit motherboard where the LED lamp beads are located, not the LED lamp beads.

In the future, this will gradually become a big trend, because this thing does save electricity, and now many families buy this energy-saving lamp to take a look at it, it is all LED lamp beads. The lighting effect has not been affected by anything, and it is more power-saving, it is not easy to burn the bulb, the life of the burner is longer, and the gradual progress of people's technology will inevitably eliminate some old things, for example, the incandescent lamp at home in the past is very power-intensive, and the lamp is not bright enough,Then it also heats up this kind of LED lamp beads to save electricity, has a long life and generates less heat, and is safer to use, of course, it is the big trend in the future.

It is very power-saving, and there are many styles, it is very convenient to operate, the power is also very sufficient, the use time is also very long, and it is also very safe and will not leak at all. So there are many people who use LED lights when decorating their homes.

These LED lights are very energy-saving and environmentally friendly, and the brightness is also very bright, which can achieve the effect of eye protection, and the practicality is particularly strong, and it is also very reasonable.

It is very power-saving, and it is particularly bright, only one lamp bead is needed to be particularly bright, and it is particularly safe and will not leak.

As LED lighting fixtures begin to enter the national era, more and more consumers want to have enough knowledge of household LED lighting fixtures. Today, let's take a look at the comprehensive analysis of the knowledge of household LED lighting fixtures for your reference.

Basic knowledge of LED lighting fixtures.

LED semiconductor light-emitting devices include semiconductor light-emitting diodes (referred to as LEDs), digital tubes, symbol tubes, m-shaped tubes, virtual changs and dot matrix displays (referred to as matrix tubes). In fact, each light-emitting unit in a digital tube, symbol tube, meter tube and matrix tube is a light-emitting diode.

Knowledge of LED lighting fixturesThe characteristics of LED light sources.

1. Low power consumption: LED with 75LM W light efficiency reduces power consumption by 80% compared with incandescent lamps of equal brightness;

2. Long life: the product life is as long as 50000h, and it can be used for 7 years after 24 hours of continuous lighting;

3. The nanosecond response speed makes the dynamic control of brightness and color easier, and the dynamic change and digital control of color can be realized;

4. Large design space: Poor and fast can be organically integrated with the building to achieve the effect of seeing only the light but not the light.

5. Environmental protection: no harmful metal mercury, no infrared and ultraviolet radiation.

6. Color: Different wavelengths produce different color light, bright and saturated, without filters, and can be controlled by red, green and blue to form different colors, and can achieve various color effects such as full color and gradient.

LED Lighting Fixtures Knowledge LED Features:

LED lighting is a green light source: low working voltage and low power consumption; Stable performance, long life (generally 100,000 hours), short response time, no pollution to the environment. Although ** more expensive than existing lighting fixtures, it is still considered inevitable to replace existing lighting fixtures.

Knowledge of LED lighting fixtures is an important reference for choosing LED lights.

1. There should be no ultraviolet light and infrared light in the spectral composition. Long-term exposure to ultraviolet rays is not only easy to cause keratitis, but also cause damage to the lens, retina, choroid, etc. Infrared rays are easily absorbed by water, and excessive infrared rays are absorbed in large quantities when they gather through the lens of the human eye, and over time, the lens will degenerate, resulting in cataracts.

2. The color temperature of the light should be close to the natural light. People live in natural light for a long time, and the human eye has strong adaptability to natural light and good visual effects.

3. No electromagnetic radiation, eliminate radiation pollution and protect the brain. It can not only provide a comfortable lighting space, but also well meet the physiological health needs of people, and is an environmentally friendly and healthy light source. Long-term use can protect eyesight and prevent myopia.

4. Zero flicker, will not make the eyes tired. The power supply frequency of ordinary fluorescent lamps is 50 Hz, which means that it is bright and dark 100 times per second when it emits light, which is a low-frequency strobe flash, which will put the regulatory organs of the human eye in a state of tense adjustment, resulting in visual fatigue. If the frequency of light is increased to more than hundreds or tens of thousands of hertz--— it becomes a high frequency, and the human eye will not have a strobe feeling; But true flicker-free is the light emitted by DC-powered or semiconductor solid-state light-emitting devices (such as LED light-emitting diodes), which is called flicker-free.
