- 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: The difference between an incandescent lamp, an energy-saving lamp, and an energy-saving LED bulb
- 3, the monomer minimum power is different. Incandescent power is a common monomer, 15W, energy-saving lamps common power 8W, and then low lighting effect is not good, and LED lamp monomer minimum power is very low, can be less than 1W.The luminescence principle of
- 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?
- Now the market LED lamps quality uneven. LED lamps need constant current and constant voltage drive to be durable. The cheap 3W LED plastic bulb power supply is only the drive of the resistance capacitance pressure drop. Drive rank: 1. constant current and constant voltage drive. 2. constant current non constant voltage drive. 3. constant pressure and no current drive. 4. resistance capacitance pressure drop drive (resistance capacitance voltage drop is the worst and cost is the cheapest)
- 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 how does the bulb return electricity?
- A 0 ohm resistor with a large point on the negative electrode
- Q: LED what kinds of screw bulbs are there?
- LED bulb is the appearance of the shape of the bulb - people have the habit of spherical internal light source is selected for LED lamp. With all the advantages of LED lamps: 1, energy saving, environmental protection; 2, long service life; 3, no stroboscopic, green.More energy-saving: LED lamp energy consumption is energy-saving lamp 1/4, incandescent lamp 1/10Long life: LED lamp life of up to 50 thousand hours, life expectancy is 5-10 times energy-saving lamps.More healthy: light evenly, no strobe, no glare, no UV and infrared.More environmentally friendly: no harmful substances such as mercury can be recycled to protect the green earth.Full color change: rich colors, vivid and delicate patterns and effects can be displayed.Installation convenience: simple installation, can replace incandescent lamp directly, maintenance cost is extremely low.
- Q: What's the reason for the LED bulb strobe?
- Currently on the market with single stage PFC driver circuit, there will be strobe, causing the flash because the ripple is too large. Single stage pFC circuits are not possible
- Q: LED can the bulb be used in the bathroom?
- From a long-term perspective is not enough, you can choose a lamp are closed, such as ceiling lamps what, now have special indoor lamps, but you must not use ordinary lamps, because LED lights to the heat at the edge of the open slot or empty, easy water.
- Q: LED bulb bulbs, do you need 3C certification now?
- Light source class is impossible to do, only lamps and lanterns class can do. For example, flat lamp, ceiling lamp and so on...However, CQC voluntary certification can be done.
- Q: Choose which light bulb LED bulb is the healthiest
- For home use, you can select LED bulb below 8W, with a color temperature below 3500K
