Q:Is there any flicker in the LED bulb?
You're right. The strobe is either determined by the driver, the current changes, or the filter doesn't work well
Q:LED what kinds of screw bulbs are there?
There are E14, E27, E40, B22, LED bulb, only these screwsThe most commonly used are the E27 sizes, and the E14 is used in small bulbs, such as refrigerators and E40, for larger power.
Q:Where can LED bulb be used?
Led bulb is now commonly used in civil products, is the most is a spherical bulb
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: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?
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's the difference between a glass cap for a bulb and a PC hood?
ProcessabilityMachinable, blister, special-shaped processing PC easier.
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:What does the LED bulb patch mean?
The patch is referring to the lamp is put up, refers to the non patch lamp is plugged in, the distinction is probably a stick is inserted.
Q:What are the requirements of the LED series inspection specification for bulb bulbs?
Insulation resistance: the lamp should not be placed for 48 hours in the damp box with relative humidity of hours. The air temperature in the box shall be controlled at any value between 20~30 degrees centigrade, and the temperature difference is within 1 degrees. The insulation resistance shall be measured in the wet box. Now the DC voltage on the lamp is about 500V. After 1min, the insulation resistance test will begin. The insulation resistance between the lamp holder, the current carrying metal parts and the accessible lamp parts shall be no less than 4M ohms.
