Bulb (Omnidirectional Light Distribution) / C21BB-EE

Light Distribution Curve

Q:Is there any flicker in the LED bulb?: First of all, I want to know what kind of LED bulb you bought. Is the LED light source small power or high power?Now on the market LED products, copycat too much, but also a lot of difference between quality and price, because the power output strobe filtering problem. Because the lowest requirements so the power design is very simple, such as shell is small power ball type PVC foam, with isolated power so far I saw several, but the price is very high, and most with the rectifier bridge, several rectifier diode, a capacitor, resistor several complete, low prices. High power type bulb is similar, but the power will be much better, is the constant current source in the output current of the filter is also doing well, there the strobe is low! Finally, the stroboscopic problem is on the power supply, and the power point difference is higher than one or two!!

Q:Where can LED bulb be used?: LED bulb is generally civilian, living room, study room, kitchen, bathroom and so on

Q:Ordinary lamp LED bulb can?: Absolutely, without any effect. It can be directly across to look at the opening of several inches.

Q:What is the 15 Watt lumen of the LED bulb?: In general, every W is 60 to 100lm, the average is about 80lm, 15W is about 1200lm

Q:What's the reason for the LED bulb strobe?: In addition, electromagnetic interference (EMI) filters are also required, even in LED drive applications that provide excellent power factor correction and support TRIAC dimming. The transient current caused by the TRIAC step (step) will excite the natural resonance of the inductance and capacitance in the EMI filter.

Q:Will the LED bulb, T8, T5 lights, radiator lamps, is the hotter the better? What's the regular temperature? What are the common heat release materials? Specifications?: If the material with better thermal conductivity, the lamp shell about 60 degrees is best.Reason:1: if the temperature is too high, that your radiator is too small.2: if the temperature is low, indicating that your calories did not lead out. (of course, if the radiator is too large and the temperature is low, but the bulb and tube are too heavy to pass by certification)

Q:LED what is the glue between the aluminum base of the bulb and the cooling aluminum?: It's best to use heat conductive glue, such as ST922.

Q:60W how many lumens and how many W LED bulb does incandescent bulb replace?: General household enough, if in 10 square meters of housing, installation of more than 10W LED lights, brightness is too good, if not the study, it is best not to.

Q:LED what does "A60" mean by bulb 60? And what does "MR16" mean?: The diameter is 60mm, but the total length of each company is not the same

Q:What are the types of LED bulb?: power LED bulb is the traditional incandescent lamp 1/10, half of the power of the energy-saving lamp, high efficiency and energy saving is the best
