Q:Detailed description of LED bulb lamp
Healthy LED is a green light source. The LED lamp is driven by DC without flicker. Without infrared and ultraviolet components, without radiation pollution, it has high color rendering and has a strong luminous directionality, good dimming performance and no visual error when the color temperature changes
Q:How to identify Ic constant current LED bulb?
Hello, LED market is now very confused, this problem is the use of LED lamps of the users are more concerned about the problem, the so-called IC constant current drive power refers to the LED lamp (commonly known as the transformer) with a constant stream of multifunctional IC chip, the IC is generally 5-8 feet (depending on the model and decision scheme), role is to ensure that the current through LED lamp is controlled in a relatively constant parameter, ensure the long-term stability of LED lamp work at constant current. When the input or output voltage is changed, the current through LED remains constant, so the constant current IC of the LED light stability and service life is directly related to the IC also includes internal short circuit protection, overtemperature protection function of open protection etc.
Q:How to choose the bulb power?
LED bulb is the appearance of the shape of the bulb - people have the habit of spherical internal light source is selected for LED lamp. Have the advantage of all LED lamps and lanterns:1, energy saving, environmental protection;2, long service life;3 、 no strobe, green.
Q:60W how many lumens and how many W LED bulb does incandescent bulb replace?
100lM/W LED bulb, 4-5W can be replaced. If it is white 4W can be, if it is warm white (yellow light), preferably 5W, mainly human eye feeling, white light than Huang Guangliang.4-5W LED bulb, equivalent to 12-15W energy-saving lamps
Q:What are the driving IC used in LED bulb?
Here are some of the models you want to know. You can contact me by mail and provide your detailed information and samples:Isolation without PFFT833S11 2.5W FT833A11 3-5WFT833B12 7-9W FT825 series 7-60WIsolation belt PFFT8900, 30W, FT8901 series adjustable light 30WFT8901B 7W, FT8901/2DD, DIP, built-in MOS, 24W adjustable lightNon isolation without PF:FT886A 7-24W FT883A 3-5W
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:How did the trademark on the LED bulb go up?
And the use of silk screen or pad printing, this is the need for the corresponding ink, this solution with a dedicated solution can be dissolved, and also have some prominent hand touch.
Q:What are the requirements of the LED series inspection specification for bulb bulbs?
Dielectric strength: electrical endurance test (resistance test) followed by insulation resistance test. During testing, the following AC voltage is applied at the specified position 1min. Type HV (220~250V); 4000V (RMS), BV (100~120V); 2U (rated voltage) +1000v.
Q:LED bulb w can replace 40W incandescent lamp
The light efficiency LED lamp better can reach more than 150lm, Hailin's general light efficiency is more than 100 in general can be done, so 3w-5w is almost completely can replace 40W incandescent lamp. Mainly depends on the quality and LED lamp lamp light etc.. The LED Lantern Festival will gradually replace incandescent and fluorescent lights, so more understanding is right. Early use, early save money. I hope there is help for your O (a _ U) O
Q:I want to ask for high power LED bulb lamp wire inexplicably broke, and in large quantities. Is the quality of the lamp?
It's possible to assemble your own bulb. The power used in the bulb is too large. It causes the gold wire to burn
