Why is the induction lamp not widely used?

I think it may be that this technology is still immature, and the price is much higher than the traditional metal halide lamp, sodium lamp, mercury lamp, etc.

Because the advertising was not done well.

I haven't even heard of induction lights.

The induction lamp that people often hear in life is a high-tech product, which has a long life and strong luminosity. Let me give you a detailed introduction.

The induction lamp consists of three parts, a bulb, a high-frequency generator and a coupler. When working, the electromagnetic field of the high-frequency generator is sensed by the coupler to the bulb, and the gas in the bulb is ionized to form plasma. The atoms in the plasma emit ultraviolet light, and the phosphor in the bulb is excited to produce light.

Most of the bulb-shaped lamps are high-frequency induction lamps, and low-frequency induction lamps are mainly rectangular and ring-shaped. The power of high-frequency induction lamps is between 10W-200W, and the power of low-frequency induction lamps is between 200W-400W, and the power with high light efficiency is also high.

Scope of application. In schools, libraries, sports fields, vegetable sheds, tunnels, factory buildings, roadsides, subway stations, railway stations, green lighting, conference halls, auditoriums, etc., especially suitable for use in places where it is difficult to change lights and high maintenance costs.

Advantages of induction lamp.

1.The start-up time is fast.

2.It's both environmentally friendly and safe.

3.There is no filament and no electrode in the bulb, and the use time can be greater than 60,000 hours, and the maintenance cost can be reduced a lot.

4.The efficiency of the luminescence is high.

5.It has strong temperature adaptability and can work normally at minus 20 degrees.

6.The power factor can be reached, or even higher.

7.There is no flicker effect, which can protect the health of the eyes.

Disadvantages of induction lamps.

1.Induction lamps are large in size and are rarely used in the home improvement market.

2.The cost is higher than other lamps, so many places give up the use of induction lamps when installing lamps.

3.The actual luminous efficiency of the induction lamp is only 65lm w, which is not as high as the theoretical luminous efficiency.

4.The country has not yet unified the norms for induction lamps.

Precautions when installing.

1.First of all, the power supply must be cut off to ensure safety.

2.If the light flickers or goes out, remove it and check it again.

3.The shield wire between the bulb and the high-frequency generator should not be cut short or lengthened.

4.When installing the bulb and the high-frequency generator, they should be grounded separately.

5.If the luminaire does not have a heat sink, neither the induction lamp nor the high-frequency generator can be installed.

6.The housing of the luminaire must be grounded.

7.The position of the high-frequency generator and coupler cannot be changed arbitrarily.

8.Do not touch the bulb with your hands after it is lit to prevent burns.

That's all for the introduction of induction lamp, I hope the article can solve your doubts and increase your knowledge.

The shortcomings mentioned on the first floor are completely layman, for now, the main disadvantage is that there are no relevant industry standards and national standards, so that some users lack confidence in the quality of the product. If there is a quality problem, it will not wait for a good solution.

In addition, the ** of induction lamp is still relatively high compared to other lighting fixtures on the market at present.

Maybe this won't be a problem in the future. Because induction lamps are the trend of future lighting development.

Pros & Cons:

1. The high-frequency induction lamp is small in size, the shape of the bulb changes more, it can be equipped with more lamps, and the old lamps can also be used with a little modification, the light efficiency is higher under the same power, and the high-speed particle flow in the bulb forms a shielding cover to eliminate electromagnetic radiation. However, due to the limitation of the size of the bulb, the power cannot be very large, usually the power can only be 200W.

2. Due to the external coupler and large volume of the lamp, the heat dissipation effect of the low-frequency induction lamp is also very good, so the power can be larger. However, due to the large size, there are very few lamps that can be matched, and some lumen loss is caused. In addition, the external coupler also makes it more difficult to solve the EMI.

Deficiencies: 1. The life problem of "induction lamp":

The theoretical life of induction lamps is 60,000 hours, but in fact, if relatively cheap components are used, including the life of "electrolytic capacitors", it will lead to only about 16,000 hours in the high-temperature environment of induction lamps, so the theoretical life cannot only be cited for publicity. In particular, the life of some induction lamps that are too cheap will definitely be greatly reduced.

2. The light effect of "induction lamp":

The theoretical luminous effect of induction lamps is only 80lm w, while the actual product luminous effect is only 65lm w. However, more of the energy in the light emitted by the induction lamp is concentrated in the visible light part near the wavelength of 550 nm, so even if the overall luminous flux is not as good as that of the sodium lamp, the induction lamp will be brighter to the naked eye, making up for this shortcoming.

3. The volume problem of "induction lamp":

Due to the special structure, the volume of induction lamp is difficult to make very small, which limits the entry of induction lamp into the home improvement market.

Induction lamp is a kind of magnetic energy lamp, which is a high-tech product developed by comprehensive application of the latest scientific and technological achievements in the fields of optics, power electronics, plasma, magnetic materials, etc., and is a new light source representing the future development direction of lighting technology with high light efficiency, long life and high color rendering.

Compared to traditional light sources, induction lamps get their name because they do not have obvious electrodes.

The induction lamp consists of three parts: a high-frequency generator, a coupler and a bulb. It is coupled to the lamp by induction through the electromagnetic field of a high-frequency generator, which ionizes the gas avalanche inside the bulb to form plasma. Plasma excited atoms emit ultraviolet light when they return to their ground state.

The phosphor on the inner wall of the bulb is excited by ultraviolet light to produce visible light.

There are too many lamps and lanterns on the market, in addition to the difference in style and color, their function and effect are not filial piety and are very different, and we come into contact with induction lamps in life, as well as three-color lights, so what does induction lamp mean?

1. Induction lamp, also known as magnetic lamp, is a high-tech product with high light efficiency and long service life. According to its working frequency, it can be divided into high-frequency induction lamps and low-frequency induction lamps, and the shape and frequency are also different.

2. The characteristic of induction lamp is that there is no filament and no electrode in it, and the service life of such a bulb can reach more than 60,000 hours.

3. The luminous frequency is also relatively high, for example, the high-frequency induction lamp is selected, which can reach 80lm per watt. It can be started instantly, and someone detects that it starts within seconds, and the temperature will be relatively low when it is started. Even in an environment of minus 25 degrees Celsius, it can operate normally and is not affected by the environment.

4. Induction lamps are relatively safe and reliable, and are green and environmentally friendly products, and the probability of maintenance or replacement in the later Youling period will be relatively small.

First, the principle of luminescence is different.

LED light: LED light emits blue light after the "positive electrode" and "negative electrode" are turned on, and the white light is emitted by the phosphor coated on the head of the inner wall.

Induction lamp: Induction lamp relies on "electromagnetic induction" to excite the phosphor coated on the inner wall of the bulb to emit light.

Second, the irradiation range is different.

LED lamp: Due to its small size, LED lamp forms directional concentrating light irradiation after packaging, which has a certain irradiation angle and small irradiation angle.

Induction lamp: The induction lamp is a spherical or ring, rectangular to the surrounding radiation, like the sun glowing, the angle can be 360 degrees, the illumination angle is large.

3. RGB spectra are different.

LED light: The blue light spectrum of the RGB spectrum of LED light is high, and there is a certain blue light hazard.

Induction lamp: The induction lamp is close to daylight, and the RGB spectrum is evenly distributed, and there is no blue light vision in the white light, and there is no blue light hazard.

Fourth, the application is different.

LED lights: LED lights are small in size and can be made into different colors, so they are not only suitable for general lighting, but also can be used for lighting around buildings and landscapes.

Induction lamp: Induction lamp is relatively large in size and cannot be used for landscape lighting.

To put it simply, LED lights are light-emitting diodes for light-emitting conditions, and induction lamps use plasma discharge for light-emitting conditions.

Each has its own advantages.

The LED structure is simpler, more convenient to use, has a long service life, and there is a slight light difference. Low light efficiency, high light.

The theoretical life of the induction lamp is 60,000 hours, but the actual service life of the induction lamp is only about 8,000 hours, the actual light efficiency of the induction lamp is also very low, and the problem of light decay is also very serious, and the attenuation degree can reach up to 50 percent after more than 1,000 hours.

If you are engaged in engineering, it is better to choose LED lights, because your contract warranty is two years, and induction lamps are basically one year to fail, and you have to repair them, so it is recommended to use LED lights.

In addition, the problem of manufacturers is mainly in some companies with more scientific and technological strength, such as Guangzhou, Shenzhen and other places, I recommend you two brands, just recommend.

Hong Kong Roche Group's Aoqi Guangdong Branch, and Tianjin Optoelectronics' LEDs are good.

Induction lamps and LED lamps are both representatives of the next generation of green light sources, and their advantages in energy conservation and environmental protection are incomparable to those of traditional light sources. However, the shortcomings of LED lamps in terms of actual use and maintenance, photoelectric parameters and cost performance are obvious compared with induction lamps, which are mainly manifested in:

1.**High and fast light decay speed, which is the defect that LED lights are difficult to popularize, the main reason is that the chip is difficult to dissipate heat and is caused by long-term use and aging. However, the induction lamp solves this problem very well, the bulb and the power inverter adopt a split design, the heat dissipation layout is reasonable, the induction lamp basically does not have the problem of light decay, and the service life is 60000 (hours), and the reasonable price has been accepted by the majority of customers.

With the same luminous flux, the lumen maintenance rate of induction lamps for 60,000 hours is 75, while the lumen maintenance rate of LED lamps for less than 4,000 hours drops to less than 50.

2.The brightness value of the LED light source is not very high, and a high-brightness LED is about 5000 candle brightness.

Induction lamps are arc discharges, and LED lamps are solid luminescent.

The induction lamp consists of three parts: a high-frequency generator, a coupler and a bulb. It is delivered through the electromagnetic field of a high-frequency generator.

Induction couples into the lamp, ionizing the gas avalanche inside the bulb to form plasma. Plasma stimulated atom returns.

Ultraviolet rays are emitted when returning to the ground state. The phosphor on the inner wall of the bulb is excited by ultraviolet light to produce visible light.

Features: 1. There is no filament and no electrode in the bulb, and the service life of the product is more than 60,000 hours.

2. High luminous efficiency, 60lm w for high-frequency induction lamp and 80lm w for low-frequency induction lamp.

3. The color rendering index is more than 80, and the high-quality trichromatic phosphor is used, and the color is not distorted.

4. Wide voltage work, the voltage can work normally in 185V-255V.

5. The working frequency is safe, and there is no strobe effect.

6. The light decay is small, and the luminous flux maintenance rate can reach 80% after 20,000 hours

7. The instantaneous start and re-start time are less than seconds.

8. The starting temperature is low, and the temperature range is large, minus 25 degrees, which can start and work normally.

9. The power factor can be as high as above.

10. Safe and reliable, green and environmentally friendly, truly maintenance-free and replacement-free.

Since induction lamps do not have electrodes, the lamp part is absent and vulnerable components are absent, and the life of the entire system depends mainly on electricity.

sub-ballast, so the life of this type of lamp is very long, can reach more than 60,000 hours. It is especially suitable for the difficulty and expense of changing the lamp.

Expensive places and important places with high safety requirements. Such as tunnels, traffic complexes, subway stations, ceilings.

Very tall factory buildings, lighting in hazardous areas, halls, sports fields, etc.

The way LED emits light is different from that of induction lamps, which have no electrodes and no filaments.
