Q:What does the LED bulb patch mean?
The LED patch (SMD) is made of FPC circuit board, LED lamp and high quality silica gel sleeve. Waterproof performance, using low voltage DC power supply is safe and convenient, light colors, bright colors; outdoor use can be anti UV aging, yellowing, high temperature resistance and other advantages, the products are widely used in building lights, decorative lighting, advertising and entertainment quasi decorative lighting lighting field.
Q:LED bulb after the power failure, still glimmer, can last hours or even all day, what is the reason?!
If the switch is installed on the zero line, LED is the resistance capacitance step-down if the light shimmer is mainly the induction voltage capacitance inside (with the switch installed on the line Never mind, because there are capacitance induction voltage). The meter won't turn. Of course, you can not expect to use this induced voltage to lighting, because this voltage is extremely weak, unable to meet the minimum requirements for lighting. If the switch is on the zero line, and there is a problem with the capacitor in the capacitive circuit, it is likely to be a long time. Over time, the circuit in the LED light proved to be a problem
Q:How to identify Ic constant current LED bulb?
The general user how to judge whether the bulb with constant current IC power supply, the general bulb is divided into three kinds, one is the RC driven RC drives are the most simple, because the cost is very low power small bulb and lamp using the scheme of small power LED bulb is often driven by RC, RC driving disadvantage is LED current with voltage fluctuation is changed, the brightness will change, so the resistance capacitance in the price is cheaper and less demanding bulb drive only, one with the IC LED driver, this there is also a constant current power supply, but the precision of constant current IC is not high, this power can only be used in the 220V voltage, the voltage fluctuation of relatively large area will affect the brightness of the LED lamp, and the stability of the power supply is relatively poor, life is better than Relatively short, easy to issue, this power supply is only a three - stage tube and two regulators circuit very...
Q:LED what is the glue between the aluminum base of the bulb and the cooling aluminum?
A lot of sticky glue can live it yourself have not tried to guess 502 good brothers of this kind of glue can be, but do not know good heat resistance and high power LED heat is still very large, if you are a small power never mind
Q:LED what are the bulb screws?
LED bulb adopts the existing method of incandescent lamp interface, the general screw is E27E14E40 (three). E for screw holes, figures for size, diameter, size. The most commonly used are the E27 sizes, and the E14 is used in small bulbs, such as refrigerators and E40, for larger power.
Q:Will the power of the LED bulb grow longer and longer? Why?
In general, LED energy-saving lamps (including LED bulb bulbs) use a constant current drive that does not change the magnitude of the current with time or temperature, so it does not become more powerful as it grows for longer periods of time.On the other hand, if because of long time use leads to LED lamp temperature rise, according to the electrical properties of semiconductor, the PN junction voltage will also decreases with increasing temperature. Then, when the current is constant, a drop in the voltage drop means a decrease in power consumption, although the reduction is very small.
Q:What's the difference between a glass cap for a bulb and a PC hood?
Weight comparisonPC specific gravity 1.2,The proportion of glass (usually glass) is 2.5,That is to say, PC is lighter in weight than glass.
Q:Is it possible to manually weld LED bulb bulbs?
You can ignore the effect of heat conduction and thermal grease, solder is better, I was doing a lot of tests, the thermal conductivity of thermal grease is about 1.2 to 2, aluminum more than 300, thermal grease just to fill the bottom of the LED and the aluminum substrate contact surface gap, you don't fill gaps don't hinder it the normal contact with the aluminum substrate at the bottom of the LED, will be lost, and the use of thermal grease you for about a year will have to replace the thermal grease, only unscrupulous vendors will deceive others say I added thermal grease, heat conduction effect is not fully qualified, in fact, for a long time, the potential will LED light spot the chip inside the loose because of the long-term high temperature, causing the current growing, until completely off
Q:LED bulb w can replace 40W incandescent lamp
I am engaged in the LED drive industry, not very professional, and I hope to help you.About brightness and energy saving comparison,1W LED=3W CFL (energy saving lamp) =15W incandescent lamp3W LED=8W CFL (energy saving lamp) =25W incandescent lamp4W LED=11W CFL (energy saving lamp) =40W incandescent lamp8W LED=15W CFL (energy saving lamp) =75W incandescent lamp12W LED=20W CFL (energy saving lamp) =100W incandescent lampBecause the company uses the light quality is not a reason, so this is not absolute.
Q:How does the LED bulb look good or bad?
Power supply must be constant current power supply. This must, do not have that resistance. The constant current source resolution methods, there is no power is apart of a 8 foot IC, if not, no junk to, also not all the IC are good stuff, a famous lighting city have specialized quality of constant current power supply.
