Q:How to choose the bulb power?
The basic types of bulb power are divided into two types: isolated and non isolated
Q:Led what's the flash of the bulb?
So, this is the power overheating protection at work. It will not be the case if the outer shell is enlarged or the room is ventilated and the heat should be cooled.
Q:LED bulb lamp drive power electrical connection, will delay a few seconds before the lamp light, and power creaks, who know what it is!
The most direct and simplest answer is the power problem.
Q:LED thread specifications for bulb bulbs?
Ordinary home E27 screw lamp ah, there is a need to ball on Taobao, art night lights, E27, E26, B22, E27 specifications in the majority! E27, E14, G10, E40 are more commonly used Oh!
Q:How did the trademark on the LED bulb go up?
Laser printing and screen printing, pad printing can be, look at the needs and equipment.
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.
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:Are there any differences between negative ion bulb and LED bulb?
The negative ion belongs to bullshit type, the concept of things!
Q:LED how does the bulb return electricity?
What is reflow? Never heard of it. I am a lighting technician
Q:I want to ask for high power LED bulb lamp wire inexplicably broke, and in large quantities. Is the quality of the lamp?
The second continued the problem: welding line, this work continued not done!
