Q:Led the bulb is flashing. What's wrong with it? How do you fix it?
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. 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: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:60W how many lumens and how many W LED bulb does incandescent bulb replace?
A LED lamp lumens general good point value is above 100;The brightness of 60W incandescent lamp compares with LED lamp difference is 10 times;
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
LED work environment refers to the external work room temperature, LED lamps also have a working temperature, general LED lamp in the case of work, the external temperature is below 65 degrees is normal.
Q:Why can't the voice switch control the time of the LED bulb?
The production lights can be controlled. Where do they go to consult?
Q:LED bulb lamp drive power electrical connection, will delay a few seconds before the lamp light, and power creaks, who know what it is!
Delays generally do not exceed 1S. After rectification, the capacitor is charged to the IC VCC terminal through the starting resistance. When the starting voltage of the IC is reached, the output switch pulse signal of IC is LED, and the luminous work is realized.. That is to say, the greater the capacitance, the longer the delay.
Q:What are the driving IC used in LED bulb?
Commonly used LED driver is based on the number of different W set, and now out of the drive program are quite a lot, according to customer requirements will also limit the number of different drivers IC.
Q:LED bulb with what type of LED beads?
Of course, the more high-end heat better use EMC3030 lamp, EMC2835 lamp and so on, please consult your supplier
Q:What's the cause of the noise during the aging of LED bulb bulbs?
The sound may be come from the power supply module components aging or faulty soldering and desoldering. LED long life, but may also be some problems.
Q:LED bulb lamp. Is there a good drive or no drive? Is the lamp of good or integrated?
LED bulb: directly driven by not using AC-LED light source, light effect of the whole lamp life (compared with driving security; some) integrated LED relative heat transfer to the high requirements, high cost, simple assembly, do a single power source in low cost, high light efficiency.
