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

Electric fluorescent starter switch role in the circuit, it consists of a neon tube and a capacitance in parallel, and the role of the capacitor to eliminate the power supply of electromagnetic interference with ballast tank formation, and increase the voltage amplitude of the start pulse. An electrode in the discharge tube with double metal, use neon bulb discharge heating, make the bimetallic strip when open and close, inductance ballast current mutation on both ends of the tube and generate high voltage pulse. When the fluorescent lamp after access circuit, electric fluorescent starter began to glow discharge between two electrodes, the bimetallic strip heat expansion and contact with the static contact extremely, so the power supply, ballast, filament and electric fluorescent starter constitute a closed loop, current filament preheating, 1-3 seconds when the heating time, electric fluorescent starter of glow discharge between two electrodes, then the bimetallic strip cooling and static contact is extremely disconnected, when two electrodes disconnect instantly, the current in the circuit suddenly disappeared, so ballast produces a high voltage pulse, and it has to do with power superposition, on both ends of the tube and, make the inert gas ionization inside the tube caused by arc discharge, in the process of normal light, ballast self-induction is still stable circuit in current role.

Q:Fluorescent fluorescent lamp tube can replace led fluorescent lamp tube?

The original circuit was an alternating current that was attached to the ballast, and the ballast two to the two sides of the fluorescent lamp; To install led fluorescent lights, remove the ballast directly, and the positive and negative poles of the exchange are connected to the two sides of the led fluorescent lamp.

Q:What happens when daylight lights go on

It will be nice in a few minutes, maybe a bad fluorescent lamp, and now it's all LED

Q:How do fluorescent tubes clean

Use damp and wet towel to wipe to be able, pay attention to want to turn off the power, lest electric shock!

Q:The notice of LED daylight lamp tube

The service life of the LED fluorescent tube, LED fluorescent lamp power saving more than 80%, life expectancy of more than 10 times of ordinary lamp, is almost free maintenance, often there is no want to change the lamp, ballast, the problem of electric fluorescent starter, about half a year down can switch back to the cost of cost savings. Green environmental protection of semiconductor lighting, the light is downy, spectrum pure, is good for eyesight protection of workers and healthy body, the 6000 k cold light source, give a person the feeling of cool and refreshing on the vision, help to concentrate, improve efficiency.

Q:What about the normal daylight tubes replaced with LED tubes, ballast and flashers?

The rectifier usually has two types of inductance and electronic type: the direct short answer of inductance (one to one). The wire and the zero line of the electronic type (two in four) are short connected to the corresponding two sets of two lines, the regenerator is pulled directly, and the LED tube is installed.

Q:Does the LED lamp need to be a national compulsory certification

Some of them need to be CCC, but most of them don't need to be CQC. This is the latest national standard. The last time I went to a certification company to listen to the lectures

Q:The various specifications of LED fluorescent tubes

LED daylight lamp tube routine parameters: 1, fluorescent lamp specifications: T8, T5, T4 difference and length of tubes, power description: commonly used with T8 and T5 fluorescent lamp specification, T4 lamp, with three tubes of a set of usually is T5 tube, commonly used fluorescent lamp specifications have T10, T12 long ago. "T", represents the "Tube", said the Tube, the Numbers behind the T Tube diameter, T8 is eight "T", a "T" is 1/8 of an inch, one inch is equal to 25.4 mm, then each of the "T" is 25.4 present 8 = 3.175 mm

Q:How much energy does normal lamp tube compare with LED light tube?

When installed the LED fluorescent lamp is very simple, the original of the fluorescent lamp to remove the LED fluorescent lamp, ballast and electric fluorescent starter, let 220 v ac mains on both ends of the LED fluorescent lamp directly. LED fluorescent lights are up to 80 percent of the electricity, and more than 10 times that of a normal lamp.

Q:The output of the led lamp is low

This should be unsegregated, and the output should be around 75v.He is unsegregated, and the output voltage is high if there is no load.
