Q:Secret LED bulb bubble price difference why so big?: Component material. Whenever cheap prices are shoddy, without exception

Q:Seeking the production process of LED bulb... Thanks: First of all, of course, the preparation of materials, the specific operation of the lamp to practice, each lamp has different methods of assembly, there are different work instructions. Only through practice can we write good and practical processes. Figure is a flow chart of MR16 assembly.

Q:LED bulb lamp. Is there a good drive or no drive? Is the lamp of good or integrated?: LED bulb lamp, are driven by a power of the ordinary small beads, driving is very simple only rectification, filtering, limiting the number of components is another large power SMD beads, this drive is more troublesome, SMT SMD components, and double plate, both have the element.

Q:What brand of LED bulb is good in quality?: The price of these lamps is very low, but the quality is not guaranteed at all. The purpose of this article is to teach consumers to distinguish the quality of LED bulbs on the market so as not to be cheated. So, which brand LED bulb is good, choose a good brand, first of all should first understand how the quality of its products

Q:LED what is the plastic shell of the bulb? What plastic material is better? What do you need to pay attention to?: PDT flame retardant plastic, good heat dissipation, flame retardant effect, you see is not very good?

Q:Is it possible to manually weld LED bulb bulbs?: As long as the welding technology clearance is possible or OK

Q:LED what is the glue between the aluminum base of the bulb and the cooling aluminum?: It is best not to direct contact with glue, glue because the thermal conductivity of aluminum than a lot of difference, even a thin layer will reduce the heat out of the speed of the screw can be used to aluminum plate and aluminum fastening together, the contact surface is smooth, when necessary, can use some conductive silicone grease amount

Q:Led the bulb is flashing. What's wrong with it? How do you fix it?: 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!

Q:The difference between an incandescent lamp, an energy-saving lamp, and an energy-saving LED bulb: 4 and three is different. An incandescent lamp relies on heating the electrode wire to send out visible light. The energy-saving lamp releases the electrons by conducting the electrode wire, while the LED light is led by the diode.

Q:How to choose the bulb power?: Obviously, the designer doesn't want the ball lights to work at rated current, but there is a margin, so the light bulb will work more reliably. Because of the constant current source, current of each lamp is not 30mA, but 330mA/13=25mA, of course, the brightness of the lights will be smaller.
