Q:Will the power of the LED bulb grow longer and longer? Why?: Could you tell me the measurement method? - how about the side current and voltage? Or, whether direct measurement of active power under mains power supply?Also, can you tell me the circuit of LED bulb? DC power supply or AC power supply? Constant current module drive or RC current limiter? If the power supply is 12 volts low, is the resistor only current limiting?I feel something doesn't make sense......In one case, the longer the duration of the LED bulb, the greater the power:In some advanced LED bulb bulbs, an anti impact "slow start" circuit is added to the design, and a NTC (negative temperature coefficient) resistor is incorporated into the LED power supply circuit.Because of the larger resistance of NTC in cold state, the current of LED is smaller and the power is relatively small;With the use of electricity LED bulbs, NTC resistance temperature gradually increased, the resistance is reduced, the current of LED is also increased, so the power LED bulb also increases, temperature stability, until NTC resistance unchanged so far.

Q:Led what's the flash of the bulb?: There are several cases of flashing lights:There is one to three flashes when the switch is switched off. This is due to an incomplete discharge of the electrolyte in the power supply.The power supply is flashing fast. This is the quality of the power supply problems, there are many specific reasons.It is found that the design of the power supply is related to the structural design of the lamp due to the insufficient margin of the power supply and the increase of temperature!The general power supply too much heat to stimulate the overheating protection function itself with the power supply, power supply is a protection device, when the heat is too large, may cause it has an adverse effect on power and light, power will take the initiative to make the lamp power, rest, fully dissipated heat later. Bright.

Q:What material is applied to the glass cover of the LED bulb? Can reach 90% of the light, can not see the inside of the lamp. Who knows, thanks for telling!: Can reach 90% of the light, can not see the inside of the lamp

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:LED bulb lamp. Is there a good drive or no drive? Is the lamp of good or integrated?: Depending on your application and cost, there's no way to say which is absolutely good;If the occasion is appropriate and the cost is not urgent, buy a drive.

Q:How did the trademark on the LED bulb go up?: Laser printing equipment is generally printed up, so that the ridge up color is not so deep, but also can not wipe off

Q:LED thread specifications for bulb bulbs?: Commonly used thread specification: E27 screw.Commonly used household ordinary E27 spiral lamp holder;

Q:What is the AC voltage of the LED bulb?: 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 3-5 times energy-saving lamps.More healthy: light evenly, no strobe, no glare, no UV and infrared.More environmentally friendly: no mercury vapor, harmful substances 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's the cause of the noise during the aging of LED bulb bulbs?: This should be the power problem. It's easy to make a noise because there are so many parts of the power supply.

Q:LED bulb is broken. The luminous patch is not bad. Can it be made into USB lamp?: Look at the LED in the LED bulb. Several LED are connected in series. Several groups are connected together, and then the voltage is estimated. Then the power of the bulb is divided by the voltage of the LED bulb to calculate the required current. Select the appropriate LED drive circuit. The average USB output current of the computer is only 100mA~500mA. The power is not enough to make the LED light achieve normal brightness, or it may damage the USB interface. It's better to use the USB charger interface. DIY needs circuit knowledge.
