Modern induction lamps

Not only LED lamps can boast of high technical characteristics today. Another option for an economical light source is an induction lamp... Induction lamps belong to fluorescent lamps, but differ in a more perfect design due to the absence of electrodes inside the bulb.

Device with an induction lamp

To create the necessary electric intensity (alternating electric field with a frequency of 190 kHz to 250 kHz), forcing the gas inside the bulb to emit electromagnetic waves, the phenomenon of electromagnetic induction is used. Therefore, the lamp is called an induction lamp.

Such lamps are produced for low direct (12 V or 24 V) and alternating mains voltage (120 V, 220 V, 277 V, 347 V), at a nominal power of 12 to 500 W and at a color temperature in the range of 2700 K up to 6500 K, typical of conventional fluorescent lamps.

During the operation of an induction lamp, several phenomena occur simultaneously: electromagnetic induction, electric discharge in gas, the glow of the phosphor — the result is the same conventional fluorescent lampHowever, induction lamps have a lifespan approximately 10 times longer than the popular CFL and HID lamps, reaching 100,000 hours.

In addition, the light efficiency of induction lamps is higher than 70 lm / W and drops by a maximum of 30% even after 60,000 hours of operation, that is, this light source is superior in energy efficiency and light quality compared to electrode fluorescent lamps. The color rendering index of induction lamps is more than 80, and the human eye perfectly perceives such light as comfortable and uniform. The heating of the bulb during lamp operation is minimal.

Modern induction lamps

Induction lamps with external and internal induction are on the market today, depending on the location of the inductor. For lamps with external induction, the inductor is located around the tube of the bulb, and for lamps with internal induction, it is inside the bulb. In addition, the electronic ballast can be located separately from the bulb or be built into the housing. The electronic ballast of an induction lamp is a high-frequency converter in which the gas inside the lamp bulb acts as the secondary winding of the high-frequency transformer.

80 watt induction lamp Venus E40

An example of an induction lamp with internal induction - the Venus E40 80 watt lamp... The lamp has a standard E40 base so that it can be installed immediately in an existing light fixture without the need to buy separately - just replace the lamp. The light bulb has the usual shape of an incandescent lamp. The color temperature can vary from 3000 to 5000 K — optimal for human perception. The guaranteed life of the lamp, declared by the manufacturer, is 14 years with a daily operation of 12 hours.

The design of the lamp is traditional for induction - no electrode... The electronics of the lamp are located in a base which is connected to an induction coil. The detachable connection of the bulb and the base-ballast allows convenient transportation of such lamps and easy installation.

The electronic ballast is made of high-quality components that will not fail even with repeated switching on / off. The volume of the bulb is large enough, so the lamp does not heat up significantly during operation, that is, the problem of overheating of electronic ballast elements will not occur.

By replacing an incandescent lamp with an induction power of 80 watts, for example in a spotlight of a hangar, in a workshop, in an office or in any room of a municipal institution, the user will receive a luminous flux of 6000 lumens with a luminous efficiency of up to 75 lm / W and will reduce the cost of electricity consumed through lighting 4-10 times. A person will be able to forget about the need for maintenance and replacement of the lamp for a long time.

This lamp will last up to 8 times longer than a compact fluorescent lamp and up to 60 times longer than an incandescent lamp. These induction lamps work without problems both in summer and in winter, even in unheated rooms such as garages or warehouses for building materials.

Induction lamp Saturn 40 W An example of an induction lamp with external induction — induction lamp Saturn 40 W... This lamp is ideal for lighting walls or ceilings, home or office, its luminous flux is 3200 lumens. More powerful models of such induction lamps are installed in street lighting projectors. 80 lm / W is a very decent light output, which speaks of the high efficiency of the lamp. Color temperature — 3000/5000 K.Guaranteed lamp life — 100,000 hours.

The electronic ballast is made portable, its device allows you to use the lamp, turn it on and off for 23 years with continuous duty cycles of 12 hours a day. At the same time, maintenance costs are reduced by about 5 times compared to other types of lamps, and you can forget about regular lamp replacement for a very long time.

As for the installation of the lamp, it can be installed directly above the workplace without relying on providing convenient conditions for replacement and maintenance. The same applies to the more powerful lamps for road searchlights - they can be installed directly above the roadway, without relying on the fact that you will often have to climb up to the searchlight to replace the worn out lamp in time, as is usually the case with sodium lamps.

In this way, the design features of the Saturn lamp eliminate the problem of excessive heating, making for a record long service life and overall very economical operation. The color temperature is as close as possible to natural light, the color rendering index is over 80. With all this, the lamp will pay for itself in 1.5 years and will last more than a dozen years. The manufacturer itself gives a five-year warranty.

Street lighting

Outdoor induction lamps are universal. They can be installed without problems both indoors and outdoors, where they can easily withstand winter frosts down to -40 ° C. In industrial and domestic premises, induction lamps clearly compete with LED lamps (see — LED street lighting).In the lighting of bridges, roads, tunnels, sports facilities, stadiums, warehouses, induction lamps will take their rightful place everywhere, even when high-quality color reproduction is required.

In general, the advantages of induction lamps are difficult to overestimate. In fact, they outperform LED lamps in real life, as LEDs lose their luminous flux faster and usually need to be replaced after 7 years, while an induction lamp will work continuously for more than 15 years, confidently retaining an average of 85% of the original luminous flux , furthermore an unlimited number of on-off cycles is allowed.

The light efficiency of induction lamps reaches 160 lm / W, and the more powerful the lamp, the higher the light efficiency, and hence the energy efficiency (economy). The efficiency of induction lamps is on average about 90%.
