What is fluorescent light How should I buy fluorescent light

In the now popular LED lights have not been widely used, people most commonly used lights are fluorescent lamps, because fluorescent lamps than other lamps used at the time, the light emitted is brighter, and to a large extent can save the home electricity bill, although it is not energy-saving compared to our current lights, but at that time it is indeed a reflection of scientific progress, but some users are still Not quite understand fluorescent lamps, today we will be in the article specifically for you to introduce some information about fluorescent lamps.

What is fluorescent lamp

Fluorescent lamps, traditional fluorescent lamps that is low-pressure mercury lamps, is the use of low-pressure mercury vapor release of ultraviolet light when energized, so that the phosphor emits visible light principle of light, so it belongs to the low-pressure arc discharge light source. A high voltage is needed when the lamp starts to ignite, and only a small current is allowed to pass when the lamp is normally emitting light, at which time the voltage at both ends of the lamp is lower than the supply voltage.

How to buy fluorescent lamps

Anti-static capacity: anti-static capacity of the led, long life. Usually anti-static greater than 700V LED can be used for LED lighting.

Brightness: LEDs have different brightness and different prices.

Wavelength: LEDs with consistent wavelength and consistent color have high price. It is difficult for manufacturers without LED spectrophotometer to produce products with pure color.

Light-emitting angle: different uses of the LED its light-emitting angle is not the same. Special light-emitting angle, the price is higher. Such as full diffusion angle, the price is higher.

LED chip: LED light-emitting body for the chip, different chips, the price difference is very large, the imported chip is more expensive.

Leakage current: LED is a unidirectional conductive light emitter, if there is a reverse current, it is called leakage, leakage current is large LED, short life, low price.

Chip size: the size of the chip to the length of the side, the quality of the large chip LED is better than the small chip. The price is proportional to the chip size.

Radiator: the radiator can look at the appearance of the lamps and lanterns, if the lamps and lanterns of the external or internal is made of aluminum, may solve the lamps and lanterns of the thermal effect so as to achieve a better prolongation of the lamps and lanterns of the life of the temperature of the LED beads play a very critical role.

Power supply: according to the design requirements of different manufacturers, can be divided into two kinds of constant current power supply and constant voltage power supply, regardless of which one, the power supply plays a central role in the service life of the whole lamp. If the lamps will break down, usually the power supply burned out.

In the above article, we introduced you to some information about fluorescent lamps, we are in this article mainly for you to introduce the basic knowledge about fluorescent lamps, you can see that we will be the content of fluorescent lamps are divided into two parts to start explaining to you, first of all, we are in the first part of the introduction of fluorescent lamps is what, this we can generally understand a little bit and then we Introduced is how to buy fluorescent lamps, we listed a lot of points, you read one by one.
