Q:Do not have the fluorescent lamp of actuator, how to change LED lamp tube?: Want to change LED lamp to match, the piece of fluorescent lamp is not usable.

Q:The lighting is replaced by LED lights and circuit problems: Remove the regenerator, remove the screw from the ballast, and then attach the red and white wires together, and wrap it in an insulating tape. Fill in the LED lamp.

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:Help me see the yellow on the left side of the LED fluorescent lamp: It should be a stabilizer module; The other, the left, 1, 3 is the inductor. 4, 5, 9 is the filter capacitor; 6 is also a capacitor; 7 is a triode; 8 is the transformer.

Q:Do the fluorescent tubes save electricity for 10 minutes, or do they save electricity in a split second?: Although the data is missing, the electric current of the opening is larger and the power consumption is no more than 10 minutes

Q:How to choose daylight lamp? What is the light bulb specification?: The fluorescent lamp shines after normal. Due to alternating current (ac) continuously through the ballast coil, the coil of self induction electromotive force, self inductance electromotive force blocking the current in the coil change, ballast step-down current-limiting role at this moment, the current is stable in the range of the rated current of the lamp tube on both ends of the voltage is stable within the rated voltage range. Because the voltage is lower than the ionization of the starter, so is no longer the starter in parallel at each end of the work, daylight lamp specifications: general search said 50 cm, 100 cm, 120 cm. Fluorescent lamp structure and function: each has a filament on both ends of the fluorescent lamp, inside the tubes filled with tiny amounts of argon and the thin mercury vapor, tube coated with phosphor, on the wall between the two filament gas when conducting an ultraviolet, the fluorescent powder soft light.

Q:How does the LED fluorescent lamp tube be fixed with the aluminum plate in the tube?: I'd better draw it. It's not all riveting, for example, using glue to press the aluminum plate to the top

Q:Buy LED fluorescent tubes to see which parameters: Power efficiency, power factor Output power (the voltage * output current of the output LED)/the input power. This parameter is especially important if the low efficiency means that a large portion of the input power is converted into heat. If it is installed inside the tubes will generate a very high temperature, and the led chip will generate heat, and would have a higher temperature, the superposition of all electronic parts within our power supply will increase with increasing temperature and shorten the service life. So the efficiency of power supply are decided life the most fundamental factor, efficiency is not too low, otherwise consume too much heat on the power supply. Power factor on the value, the power factor is the ratio of active power and apparent power, namely the cosine Φ = P/s. low power factor, can produce a large amount of reactive power, power efficiency and will also cause disturbance to the grid, it will be high to the requirement of engineering and the factory! General requirement efficiency is above 80, power factor is above 0.8. 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.

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:What happens to the daylight bulbs: The lamp tube is aged, or the quality is poor, the new test can be changed, or the part of the starting circuit has a problem.
