- Q:What's the reason for the LED bulb strobe?
- 8W offline LED driver GreenPoint reference design with solid state lighting standard energy star "as an example, the sine wave regulator side flyback power conversion does not provide constant energy to the primary bias, dynamic self supply (DSS) circuit can be activated and the light induced flicker. To avoid this problem, it is necessary to allow primary bias to be discharged at each half cycle, and accordingly, the values of the capacitance and resistance that constitute the bias circuit need to be appropriately chosen.
- Q:How to choose the bulb power?
- If the public is not high, the quality requirements, and to control the price, you can choose non isolated, because it does not require isolation transformer, so the cost is relatively low, but the aluminum substrate voltage requirements is relatively high, otherwise there may be charged radiator, and still light outside is not very beautiful.
- 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:Who knows where the broken LED bulb is?
- The proposed open, lamp is broken, can find light black or other unusual circumstances, bad power supply at the circuit board and components have the same burn what, under normal circumstances is such.
- 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:What are the driving IC used in LED bulb?
- MT7930, LM3445MM do bulb bulb, the effect is also ok.
- Q:What are the types of LED bulb?
- According to the radiator shell to points, can be divided into plastic shell, aluminum radiator and ceramic shell, in general, the ceramic shell heat radiator is best, but the price is relatively expensive, the widespread use of aluminum shell, moderate price, good heat dissipation performance
- Q:LED bulb with what type of LED beads?
- There are many LED bulbs with LED lamp types, different lighting manufacturers will adopt different LED models, at present, most of the 2835, 5730 beads, beads are 0.5W-1W LED beads, specific type: PL-P2835DW-C8-R3-C2/ PL-P5730EDW-C8-R3-C2
- 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 what does "A60" mean by bulb 60? And what does "MR16" mean?
- 60: diameter 60mm (metric unit) MR16: diameter is 16*1/8*25.4mm (Imperial units), although refers to the diameter, but the height and other dimensions are also prescribed
