Q:What's the reason for the LED bulb strobe?
If this resonant characteristic causes the input current to fall below the TRIAC sustaining current, the TRIAC will turn off. After a short delay, the TRIAC usually switches on and fires the same resonance. In the 1.5 cycle of the input power waveform, this series of events may be repeated several times to form visible LED flashes. To cope with this problem, a key requirement of TRIAC dimming is that the input capacitance of the EMI filter is very low and that the capacitor is decoupled through the TRIAC and the winding impedance. According to the formula, if the capacitance of the dimming module is reduced, the resistance of the resonant circuit can be increased, and the oscillation is suppressed in principle, and the desired circuit work is resumed.
Q:How to choose the bulb power?
The basic types of bulb power are divided into two types: isolated and non isolated
Q:What does the LED bulb patch mean?
The LED patch (SMD) is made of FPC circuit board, LED lamp and high quality silica gel sleeve. Waterproof performance, using low voltage DC power supply is safe and convenient, light colors, bright colors; outdoor use can be anti UV aging, yellowing, high temperature resistance and other advantages, the products are widely used in building lights, decorative lighting, advertising and entertainment quasi decorative lighting lighting field.
Q:LED thread specifications for bulb bulbs?
Specifications also include bulb, E27, E26, B22, E14, G10, E40;E27 specifications are in the majority.
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: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 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 characteristics of LED bulb?
The service life is long, and the average life can reach 100 thousand hours.
Q:LED what are the bulb screws?
LED bulb adopts the existing method of incandescent lamp interface, the general screw is E27E14E40 (three). E for screw holes, figures for size, diameter, size. The most commonly used are the E27 sizes, and the E14 is used in small bulbs, such as refrigerators and E40, for larger power.
Q:LED what does "A60" mean by bulb 60? And what does "MR16" mean?
MR is a reflector that is represented by a plurality of reflector groups, and 16 represents the maximum outer diameter of 1/8*16*25.4=50
