Main Technology Index:

Q: Are led fluorescent tubes not available for lighting?: It is also possible to use a stent without a stent, usually with a negative level on the positive side of the connection

Q: Fluorescent lamp double lamp tube wiring method: Is ok, if the electronic ballast, take a look at is a of the area, or area of two, if is one of the region, the four lines of the same light foot directly connected to the ballast end (the end of the four terminal) ballast directly connect the power cord is ok, on the other side of the ballast area 2, the light of the light feet a line connected to the ballast, on the other side of the ballast connect the power cord is ok!!

Q: How long does the energy-saving daylight lamp tube change?: You didn't say you were satisfied with the brightness you had just installed three years ago. If the brightness drops only if the brightness decreases with time, replace the lamp with a reduced brightness in time.

Q: How does the LED fluorescent lamp tube be fixed with the aluminum plate in the tube?: The person thinks still silicon fat + screw, but the screw is not easy to install, do not know the big man has the gao zhao4?

Q: Is an LED 20 watt equivalent to 40 tubes?: The equivalent of 40 to 60 w. Theory led luminous efficiency is more than 10 times of incandescent lamp, energy-saving lamp is 2 to 3 times, but according to the feeling of the human eye not probable, because the led color temperature difference is very big, also is white is a lot of kinds, unlike CFLS in general only warm white (3000 k) is the white (4500 k) two kinds, calculate by is white multiples this is true, but when the temperature above 6000 k will feel a lot of dark, smooth color slants, a bit like a jack-o '-lantern, so buy the led lamp in the guest is white, the bedroom to warm white (3500 k) advisable, can't see how much watts.

Q: What is the connection of the LEDT5 lamp tube, the main line is how to connect, only to the end: 1, the installation: The LED comes with a constant current source, which does not require a ballast and a regenerator. General T8 lamp tube because the lamp tube space is big enough, constant current source can be installed in the lamp tube. So, when installing, you can remove the ballast from the original frame and remove it, and install it directly. T5 fluorescent lamp, T4LED because tubes is very small, not put constant current source, can only be constant current source in a scaffold, so, T4 / T5 general manufacturers are doing, will deploy stents, stent in persistence current source, and the lamp installation direction of the. The direction is reversed, the lamp is not bright. We are considering adding some switching circuits to allow the lamp to work properly even if the lamp is in reverse. Voltage: to communicate 85V -- communicate 245V, all can work normally. However, the long-term voltage is too high or too low, which can affect the power factor of the constant current source, which means that the effect of energy saving will be slightly affected. At the same time, it can also affect the lifetime of the constant current. So, want to choose the fluorescent lamp that is appropriate voltage commonly.

Q: The ledt8 lamp is used for the light bulb: Generally see you want how much wattage T8 tubes, according to how much wattage to order the lamp bead, generally a lamp bead is 0.5 w, according to the wattage calculate knew how many light bead

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: Why do LED bulbs have stroboscopic frequency? The camera: There is a difference between the eye and the camera. This is caused by the ripple current, and this general customer will be required. It will be down to 10%

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.
