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:Secret LED bulb bubble price difference why so big?: Lamp beads。 I also do with Samsung bulb, bulb, lamp light cost more than others product price;

Q:What's the difference between a glass cap for a bulb and a PC hood?: Transparency comparisonPC transparency is 90%, glass transparency is 95%, but the naked eye does not seem to distinguish between too big, because it is 5%, ha ha,Only several meters can be measured by instruments.

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

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's the flash of the bulb?: Should be the cheapest LED bulb, the lamp driver is not a constant current source, in the voltage fluctuations will appear flash.

Q:Led the bulb is flashing. What's wrong with it? How do you fix it?: 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!
