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:The ambient humidity of the LED daylight lamp is in the range

If you're in a particular high humidity environment, don't use an ordinary led fluorescent lamp, considering the safety of an led lighting device that USES waterproof dust

Q:The ledt8 lamp is used for the light bulb

The average LED T8 lamp is based on the number of lamps in the wattage, and the average light bulb is 0.5 w, and according to the wattage, you know how many lamps are there.

Q:If you want to replace it with an LED fluorescent tube, how many watts does it take?

This depends on the type of the lamp. For example, the bulb bulb, LED and incandescent, usually we calculate at 1:7 or 1:8, and there is a 1:10 calculation.

Q:The notice of LED daylight lamp tube

Without ultraviolet light, no LED lights will not produce ultraviolet light, so unlike traditional lamps, there are a lot of mosquitoes around the light source. The room will become cleaner and cleaner. A voltage adjustable 80v-245v traditional fluorescent lamp is lit by a high voltage released by the rectifier, which cannot be lit when the voltage is lowered. LED lamps can be lit in a range of voltages, and can also adjust the brightness

Q:How do I get the four joints of the LED fluorescent tube, and I'm going to do any two of them that can search through the AC220V to light up, and not make the wire and the zero line together? thank you

The LED fluorescent tube In fact, it is the connection column of the ordinary daylight lamp, the four connecting bars, each of which is 220V The LED fluorescent tube, which is connected to the AC DC transform at 220V, gives the internal LED power supply According to the internal implementation of the LED tube (whether the two ends are in parallel) At least two terminals at one end, which can be lit up by 220V, may be connected in parallel to this end, or an empty terminal

Q:Where is the very thin daylight lamp usually bought?

There's no need for a lamp slot for the hardware store. Because it's on the lights. Most of them are screwed. The light bulb of a home. You don't need to buy a switch. General 26 w.. 20 yuan

Q:Is there any LED fluorescent lamp that can be used for more than five years?

LED lights are used for start-up time, and if it is open tomorrow for four to five hours it should take five years, but there will be light decay.

Q:What kind of lamp tube is the 2G11 lamp of LED fluorescent lamp

The T8 / T10 is named based on the diameter of the tube, such as T8 is 26mm and T10 is 30mm. The two g11 is a single and two-tube type, and the lamp can be paired with a single row of four pins, which can also be double-lined

Q:Brightness, longevity The current led lighting tube is 90-100lm/watt, and the life span is more than 20,000 hours, and the chips and power supply should be paid attention to. We adopt a 3-ampere, long power supply to ensure the quality of the lamp.

Of course, some of the less known and inferior brand LED lights for one-sided to cater to consumer demand, in driving circuit to make the LED work under the condition of more than rated condition, light efficiency is very high, but the disease also is very obvious, the working life will be very short, light failure is severe, a period of time will be significantly dimmed. Therefore, when choosing a product, pay attention to the mainstream product of big brand, don't pay too much attention to light effect. This is especially true of the hybrid.
