- Q: LED bulb PC, will the white cover affect the color temperature of the finished lamp?
- PC Ivory lampshade, because of the low price, it is recommended to use light diffusion cover, so this should not be the problem
- Q: LED what is the glue between the aluminum base of the bulb and the cooling aluminum?
- A lot of sticky glue can live it yourself have not tried to guess 502 good brothers of this kind of glue can be, but do not know good heat resistance and high power LED heat is still very large, if you are a small power never mind
- Q: What are the driving IC used in LED bulb?
- M8900 can replace BP3309, SY5810 SY5840 MT7930, ME 8316, without modifying the circuit used directly.M8900Is an original side feedback, with single stage active PFC high precision LED constant current control chip, M8900 integrated single level active PFC line, can achieve higher power factor and very low total harmonic distortion, chip canThe quasi resonant mode is achieved, thereby achieving higher efficiency and reducing switching losses. M8900 features multiple protection functions to ensure system reliability, including LED open circuit protection, chip overvoltage protection, and UVLO deficiencyVoltage protection, LED short circuit protection, cycle by cycle current limiting, etc..
- 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 w can replace 40W incandescent lamp
- The standard of luminous flux according to the luminaire is lumen (LM). Incandescent lamps are w 11-12lm per 40w=440-480lm
- Q: What's the reason for the LED bulb strobe?
- Common causes and treatment of LED light flashing:Generally, the human eye can detect light flashes with frequencies up to 70 Hz, which are not sensed above this frequency. Therefore, in LED lighting applications, if the pulse frequency appears below 70 Hz low-frequency components, the human eye will feel flashing. Of course, in specific applications, there are a variety of factors that may cause LED lights to flicker. For example, in offline low power LED lighting applications, a common power topology is an isolated flyback topology.
- 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: LED bulb after the power failure, still glimmer, can last hours or even all day, what is the reason?!
- Because LED's normal luminous current is 20MA, and LED has a weak current, it can emit light. According to this source. Maybe your line is just on the zero line. This will lead to a small leakage current flows through the LED lamp.Try offline.
- Q: Will the power of the LED bulb grow longer and longer? Why?
- The LED bulb does not become more powerful for extended periods of time.As LED chip light emitting device of the PN junction has a negative temperature characteristic: with the increase of temperature, the conducting voltage drop caused current rise, therefore, when the LED bulb is lighted with the temperature rise of power consumption will be increased. But good circuit and parameter design can reduce the influence of this temperature.
- 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.
