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:LED bulb is broken. The luminous patch is not bad. Can it be made into USB lamp?
LED bulb is broken. The luminous patch is not bad. It can be made into USB lamp.LED bulb is usually a series of LED series, and then parallel, generally about 12V.Single chip LED generally rated voltage at 3.0V~3.6V, USB, output voltage of about 5.0V.Look at the LED in the LED bulb. Several LED are connected in series. Several groups are connected together, and then the voltage is estimated.Then the power of the bulb is divided by the voltage of the LED bulb to calculate the required current.Select the appropriate LED drive circuit. The average USB output current of the computer is only 100mA~500mA. The power is not enough to make the LED light to normal brightness, or it may damage the USB interface. It is better to use the USB charger interface.Light emitting diodes, referred to as LED. Made from compounds containing gallium (Ga), arsenic (As), phosphorus (P), nitrogen (N) and so on.
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:What are the requirements of the LED series inspection specification for bulb bulbs?
Anti torque test is carried out using only suitable for torque meter, torque test, lamp holder should be firmly bonded on the lamp or lamps used to purchase spin spin out parts, E26 and E27 for 3N*m.
Q:What's the cause of the noise during the aging of LED bulb bulbs?
The power supply LED bulb using miniature low power switching power supply, switching transformer due to loose, and the switching frequency did not avoid the audio area, it will beep.
Q:What does "A19" mean in LED A19 bulb?
A19 is the European A60: represents the outer diameter 60mm=19/8*25.4=60.325mm, such as the diameter of the A19 bulb. "D=19*1/8", multiplied by 25.4, is the diameter of the bulb in mm units. The source of this formula is the same as the T8 tube: "X" in Tx means that the diameter of the tube is x times 1/8 inches, so the diameter of T8 is 1/8 inches x 8=1 inches, or 25.4mm
Q:LED what is the glue between the aluminum base of the bulb and the cooling aluminum?
Heat conductive adhesive is best.Heat conductive adhesive, also known as thermal conductive silica gel. Organic silica gel as the main body, adding fillers, thermal conductive materials and other polymer materials, mixed by silica gel, has better thermal conductivity, electrical insulation performance, widely used in electronic components. Also known as: thermal silica, silicone rubber, silicone heat, thermal conductivity of silicone. The accelerator is used to solidify a transformer, transistor, and other heating elements onto a printed circuit board assembly or radiator
Q:What are the characteristics of LED bulb?
Less power consumption, a 5 Watt LED bulb, equivalent to 40 watts of ordinary incandescent.
Q:Choose which light bulb LED bulb is the healthiest
The two said warm light, power, color temperature and so on have little to do with health
Q:Why is 3W's LED plastic bulb so cheap on the market? Is there any drawback to the price difference between aluminum and aluminum?
The first is Aluminum Alloy better heat dissipation, aluminum is relatively high, and made products, together with the positive effect is not the same, in addition, the wick and the circuit there will be differences, this will also affect the application of life and feelings.
