Q:Is it possible to manually weld LED bulb bulbs?
Well, the lights go straight up, aging, usually 24 hours of aging, testing, you have to open 10 seconds, 10 seconds off, so non-stop switching for 2 to 4 hours
Q:60W how many lumens and how many W LED bulb does incandescent bulb replace?
A LED lamp lumens general good point value is above 100;The brightness of 60W incandescent lamp compares with LED lamp difference is 10 times;
Q:What's the reason why LED bulb gets a lot of heat?
If the radiator has a large radiating area, the temperature is low
Q:LED thread specifications for bulb bulbs?
Commonly used thread specification: E27 screw.Commonly used household ordinary E27 spiral lamp holder;
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 bulb w can replace 40W incandescent lamp
The light efficiency LED lamp better can reach more than 150lm, Hailin's general light efficiency is more than 100 in general can be done, so 3w-5w is almost completely can replace 40W incandescent lamp. Mainly depends on the quality and LED lamp lamp light etc.. The LED Lantern Festival will gradually replace incandescent and fluorescent lights, so more understanding is right. Early use, early save money. I hope there is help for your O (a _ U) O
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 material is applied to the glass cover of the LED bulb? Can reach 90% of the light, can not see the inside of the lamp. Who knows, thanks for telling!
Can reach 90% of the light, can not see the inside of the lamp
Q:LED what are the bulb screws?
Ordinary bulb is the most common, is a metal electrode which is threaded, so it requires that one electrode when installing the socket contact thread to pick the zero line, the middle dot electrode lamp power. Otherwise, an electric shock occurs when an accidental contact with the exposed metal. Because of this symmetrical way, the bulb can be threaded to fit the socket.
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.
