What is a lamp amp? Revealing the principle and operation of the Lamp Amplifier

Lamp amplifier is a new term for those who are new to Amplifier. Unlike other amplifiers, the lamp amplifier has a more special operating principle and structure. Let’s refer to Tnhelearning.edu.vn right away What is a lamp amplifier? Reveal the principle and how the lamp amp works!

What is a lamp amp? Structure of Lamp Amplifier

The device that relies on the operating principle of the light bulb to amplify the sound is called a lamp amplifier. In other words, the lamp amplifier will amplify the signals as they pass through the component system. Therefore, the device brings the world’s most unique sound quality.

In recent times, Amplifier has developed strongly and widely applied in many fields such as listening to music, television, transmitting phone signals,…

Structure of Amplifier :

The bulb in the Lamp Amplifier is divided into 3 components:

• Cathode: Where an electric current is supplied, the electron emission capacity of this part is enhanced by surface coating with various compounds.
• Anode: Having a positive potential, gaining free electrons.
• G pole : Carry the negative electrode. Is the control pole, has a grid or spring form located between the cathode and anode poles.

It’s all housed in a glass shell that has pumped air out to achieve a near-vacuum state. As a result, the internal components are not oxidized, and do not interfere with the active current from the cathode to the anode, resulting in better sound quality.

The current flowing through the bulb is large or not depends on many factors as follows:

• Cathode surface coating.
• The cathode and anode voltage difference.
• Cathode and anode surface areas.

How it works and the principle of the Lamp Amplifier

In order for the lamp amplifier to work, the cathode pole is heated to a certain temperature, causing the electrons to have more kinetic energy than the metal binding force. From there, they begin to emerge from the surface of the cathode. Equipment that uses electricity mainly serves the cathode heating process.

However, a lot of energy is wasted and lost in this process, because the efficiency of converting electricity into heat is usually not great. When connecting to an Amplifier, it is necessary to have a speaker with high sensitivity, because the movement of electrons makes the current through the bulb very small. Therefore, the smallest vibrations can still be felt.

Some types of Ampli bulbs

Amplifier bulbs are of two types: audio preamps and power bulbs. Each type of light bulb has a different function.

Audio Preamplifier

The audio preamplifier used in the pre-amplification stage has the effect of enhancing the signal flow to have enough strength to move to the next stage, because there is a small signal level to the Amplifier.

Noise is increased with the audio signal, it will affect the sound output. Therefore, this stage should not be mixed with noise. Manufacturers have sucked up all the air in the bulb and the outside of the lamp is also coated with an anti-interference layer, which helps to prevent the sound from being mixed with noise.

Power ball

The power bulb belongs to the audio frequency amplification stage. This is one of the parts that play an important role in the quality of the audio signal through the amplifier, used to turn the audio signal from the preamplifier strong enough to output the load.

Therefore, manufacturers as well as customers when buying Lamp Amplifiers are interested in power bulbs. During use, in order to ensure sound quality and meet the needs of good use, you can replace the components according to the lamp periodically.

The outstanding sound characteristics of the lamp amplifier

Lamp amps have an old-fashioned feel to their sound and deliver a particularly impressive sound quality that other amps don’t. Amplifier lights have two outstanding sound characteristics are Analog sound bar and Amplifier is not limited by a sound quality.

Analog Audio

The impressive highlight of the Lamp Amplifier that attracts many customers is the Analog sound bar, which helps to bring natural, smooth , and thick sound. This sound is loved by many people, most notably those who love music, composing, and studying music. If you’ve ever heard of a graphite disc, you’ll understand why this device is so popular.

Currently, on the market, there are a variety of lamp amplifiers with different production brands, technologies and designs. Therefore, not all lamp amplifiers are the same. Each amplifier has different characteristics and sound quality, depending on your preferences and needs, you have your own choice.

Amplifier is not limited by one sound quality

When the user replaces the bulb with another, the sound quality will be different. This is one of the unique characteristics of the lamp amplifier, which attracts many consumers. Each bulb will have an operating voltage, operating amperage as well as other outstanding characteristics.

Therefore, it requires you to be a person with sound knowledge to be able to understand. Users can plug in the lead from the light amplifier to another amp that can still work normally, but each type will have its own distinct sound characteristics.

Users need to pay attention to the group of light bulbs when using the Amplifier as well as changing the light bulb, in order to use the Amplifier better, providing good sound quality, without interference.

The pros and cons of the lamp amplifier

In addition to the outstanding features of sound quality, users need to learn carefully about the advantages and disadvantages of Lamp Amplifiers, to have a suitable product choice and quality.

Advantage

• When the amplifier is in operation, the lights are illuminated , looking very eye-catching and creating a romantic, unique and magical space.
• You are free to replace the bulb models you love.
• The sound is warm, smooth, sweet, and authentic.

Defect

• Clean regularly because the device is easy to collect dust. In particular, when cleaning, you must carefully wipe every detail and be gentle so as not to damage the bulbs.
• The cost is higher than conventional amps. At the same time, every time a new light bulb is changed, a fee is charged.
• Difficulty in pairing with music or karaoke speakers because the operating capacity of the lamp amplifier is quite small.
• The bass intervals are not really strong and powerful.
