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:What is the most suitable power efficiency for leds?

It's about 0.97, it's still pretty high, I bought the lamp tube of zhaochang, very bright, used for two years, still like new

Q:The T8 nominal 36W standard daylight bulb is only 18W

It's just wrong! Hope to do more scientific spirit LED torch, less business practices, builders of the LED lighting products, don't wait for a day, LED lighting products are reduced for the waste products

Q:The circuit board in the LED fluorescent tube, what's the name of the component?

Have a what ah, whether to the power supply circuit, or light board, if do the power, you don't know now components, estimate for would you don't, schematic diagram, you seek me, send me zhang is out of date, don't mind, the new product is company secrets, if you want to power supply, it is good to look for me directly

Q:The lamp tube of LED lamp is full plastic lamp tube good or half plastic half aluminium tube good?

The whole plastic lamp tube mainly USES the non-isolated power source, in order to avoid the electric shock problem, so adopt the whole plastic lamp tube. It USES a phi 5 hat tube LED. The biggest problem is that the cooling problem, because all the heat sealed in tube, don't spread out, the light failure is severe, plus straw hat tube original life is very short, less than 2000 hours it broke. And half plastic and aluminum tube is the market sales of the LED fluorescent lamp is essentially the half PC alloy, in need of pervious to light the plastic, half without pervious to light and the need to adopt aluminum alloy heat dissipation of the half. The power is placed inside the aluminum tube, so the heat from the LED and the heat from the power supply is quite large, since the power of the lamp is usually around 20W. The power is larger, and the semi-aluminum tube doesn't solve the heat problem. Leds are English light emitting diode (LED), its basic structure is an electroluminescent semiconductor chip, silver white glue or adhesive curing to the bracket, and then use silver or gold wire connection chip and circuit board, and then sealed with epoxy resin around, protect the internal core, final installation of the shell, so the LED of the seismic performance is good. The area of application involves cell phones, lamps, electrical appliances and other household appliances and machinery production

Q:What does philips mean by TLD36w / 54-765

Yeah, I did it for you, I think it's the bottom, Let's see if it is ~ TLD ~ T8 Dailyght 160-240v (model) 36 ~ 36 w.I hope my answer will work for you.

Q:LED energy-saving integrated fluorescent lamp tube, in the center has four segment interconnection, when the dark halo light is not known to be that electronic parts failure.

Integration tube: currently, mainly appears in the LED industry, design reason mainly lies in the fact that the LED itself is not easy to damage, but the LED heat emitted by itself is very big, if the cooling area is too small, easy to cause the droop is bigger, so will the lamp and stents design together at the same time can reduce the cost, and can ensure the LED light attenuation!

Q:How is the T8LED fluorescent lamp installed?

If it is old fashioned, you must cut the input of the ballast and install it as shown below.

Q:Does the installation of LED fluorescent bulbs need to be positive and negative

LED has no brand, only quality The factory can purchase raw materials according to customer requirements. Like we can do middle eastern countries and we can do European and American countries.

Q:Help me see the yellow on the left side of the LED fluorescent lamp

The black patch in the rear of the capacitor is the MOS tube, the electric inductance behind the MOS tube, the optical coupling behind the inductance, and the electrolytic capacitance behind the optical coupling.
