Q:How to choose daylight lamp? What is the light bulb specification?

The principle is: when the switch is switched on, the power voltage is passed through the ballast and the lamp filament to the two poles of the regenerator. The voltage of 220 volts immediately disassociates the noble gases of the regenerator, producing glow discharge. The heat of the glow discharge heats up the bimetal plates, and the poles are in contact. The current flows through the ballast, the regenerator, and the two ends of the filament. The filament is quickly heated by the current and emits a lot of electrons. At this point, the voltage between the poles is zero because the regenerator is closed, the glow discharge disappears and the temperature in the tube decreases. The bimetal strip is automatically reset and is disconnected. At the moment of the disconnection, the current of the circuit is suddenly cut off, and the ballast generates a large self-inductance, which is applied to both ends of the tube with the power supply voltage. The large amount of electrons emitted when the filament is heated, under high voltage at both ends of the lamp, is moving at maximum speed from low voltage to high potential end. In the process of accelerating motion, the argon molecules in the collision tube are rapidly ionized. Argon is ionized by heat, which causes mercury to produce steam, and the mercury vapor is ionized and emits a strong ultraviolet light. In ultraviolet light, the phosphor powder in the tube walls emits near-white visible light.

Q:What material is LED fluorescent lamp fittings, such as shell, block?

It is mainly PC + aluminum, the PC cover is not easy to break, aluminum does heat dissipation, the light heat is good

Q:Can leds be used for a regular fluorescent lamp?

Ballast. It turns out that the ballast has two wires in and out, and four broken wires, connected by color. For example, the broken head of the red fire connects red. Two connections in other colors.

Q:Xinda is a popular led lighting tube

The led tube is required to be divided into several grades. The general engineering level is high, the quality is stable, the quality assurance time is long, the price is relatively high.

Q:What causes the red light on both ends

There are two kinds of red light on both ends of the fluorescent tube: 1, if it is the use of long tube, gradually from both ends of black, red in the end, there is a gradual process, is basically a lamp aging, filament will burn out the precursor, exchange tubes can troubleshooting; The lamp tube USES all the time normal, occurrence afore-mentioned phenomenon suddenly, that most is the rectifier is caused by failure, change rectifier can.

Q:How does the lamp line connect

Briefly said, fluorescent lamp need to shine at the beginning of the start to a transient high pressure, the pressure is greater than 220 v, ballast can produce the instantaneous high pressure, help the fluorescent lamp. Before the lamp to shine, in addition to need ballast, also need a starter starter (scientific name:), like many tubes above the starter without this now,

Q:Why don't leds and light bulbs adjust brightness by dimming switches

There is something that can be supported, usually for a price that is inexpensive, because the traditional ones don't do the dimming

Q:Now there is no led lighting, just like the fluorescent light bulb, which is universal

Yes, on some treasure, I have just changed a batch of such tubes, no more than 8 yuan or so.

Q:What is the idea of an LED daylight lamp called T5 or T8?

The integration of tubes: mainly in the traditional lamps and lanterns, also is the T5 trichromatic lamp, as a result of the three primary colors T5 tubes need rectifier, and trichromatic lamp life is limited, the designer in order to facilitate the rectifier and convenient replacement bulbs, use of integrated design. Now the LED lamp just began to enter the market, many companies also modeled on the traditional lamps and lanterns to design.

Q:How to replace old lamp tubes with LED tubes

LED fluorescent lamp, does not need a ballast, regenerator. Simply remove the ballast from the traditional fluorescent lamp holder, and then install the LED fluorescent lamp.
