Quality Control

 

1. 100% of the lamps will be tested and keep lighting for 24 hours to test its quality reliability

2. we will also test its temperature after 24 hours lighting

3.  after it is cool we again test 100% of the lamps to see if it still work well

4. all lamp should pass all these QC procedures before the packing.

 

Features

 

1) We use high quality SMD LED as light source, which is high brightness, long life and less heat

Q:Secret LED bulb bubble price difference why so big?
Power Supply。 Good quality will be equipped with power supply, usually in the lamp cavity. And low prices are put on the lamp board with several capacitive resistance to deal with
Q:What's the reason for the LED bulb strobe?
Currently on the market with single stage PFC driver circuit, there will be strobe, causing the flash because the ripple is too large. Single stage pFC circuits are not possible
Q:What is the AC voltage of the LED bulb?
The AC voltage of LED bulb is usually 220V, and the power is divided into 3W, 5W, 7W, 8W, 9W, 12W and so on.The biggest market for LED bulb lighting is the civilian market, and the LED bulb is a new green light source to replace the traditional incandescent bulb. LED lamp has the advantages of energy saving, environmental protection, long service life, no stroboscopic, green and so on.
Q:Why can't the voice switch control the time of the LED bulb?
Current problem. The current is too weak. You don't have to use an electric meter to see if you can work properly without a light bulb. Change the timer switch.
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.
Q:In a bulb, the ambient temperature of the LED is LED, the temperature of the air in the bulb, or the temperature of the aluminum substrate
The standard is the body temperature of the LED lamp. With a multimeter probe is placed in the LED lamp bulb angle can be measured temperature. Generally -20~80 degrees centigrade
Q:Are there any differences between negative ion bulb and LED bulb?
LED bulbs are made by plug-in lights or SMD or high-power LED, and there is no built-in negative ion generator.
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:The difference between an incandescent lamp, an energy-saving lamp, and an energy-saving LED bulb
3, the monomer minimum power is different. Incandescent power is a common monomer, 15W, energy-saving lamps common power 8W, and then low lighting effect is not good, and LED lamp monomer minimum power is very low, can be less than 1W.The luminescence principle of
Q:How to identify Ic constant current LED bulb?
Look at the power supply, there are a few simple electronic and capacitive circuit board, it is not constant flow, cross flow is larger, so understand? Cross flow IC, that is, the meaning of intelligent voltage regulator, so that the LED is not easy, bad capacitor driven LED is relatively easy to damage, easily breakdown, and power consumption than the cross flow
