Q:Is there any flicker in the LED bulb?

You're right. The strobe is either determined by the driver, the current changes, or the filter doesn't work well

Q:LED what kinds of screw bulbs are there?

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. With all the advantages of LED lamps: 1, energy saving, environmental protection; 2, long service life; 3, no stroboscopic, green.More energy-saving: LED lamp energy consumption is energy-saving lamp 1/4, incandescent lamp 1/10Long life: LED lamp life of up to 50 thousand hours, life expectancy is 5-10 times energy-saving lamps.More healthy: light evenly, no strobe, no glare, no UV and infrared.More environmentally friendly: no harmful substances such as mercury can be recycled to protect the green earth.Full color change: rich colors, vivid and delicate patterns and effects can be displayed.Installation convenience: simple installation, can replace incandescent lamp directly, maintenance cost is extremely low.

Q:What are the driving IC used in LED bulb?

The analysis report shows that nearly three years, the domestic market share of LED lamps will increase from 5% to about 20%-30% can be seen, LED is now the need to walk into the homes of ordinary people, so we need to control the cost, cost is the main driving power LED lamp and a shell, a power driven material faster BOM province can let the promotion of LED. As the LED lamp has the characteristics of energy saving and environmental protection, the state has also subsidized the product accordingly.

Q:Led what's the flash of the bulb?

So, this is the power overheating protection at work. It will not be the case if the outer shell is enlarged or the room is ventilated and the heat should be cooled.

Q:What advantages does LED bulb replace energy saving lamp?

The LED lamp is solid-state lighting, if all LED lamps a year remaining nearly three electric power Three Gorges hydropower station, the country.

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:Choose which light bulb LED bulb is the healthiest

The two said warm light, power, color temperature and so on have little to do with health

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: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: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
