The poor toughness of the copper wire or the flexible printed circuit board of the LED engineering light strip will cause the LED engineering light strip to break when it is bent, and also affect the service life of the LED engineering light strip. Power factor, LED technology lights are usually powered by a constant voltage power supply (DC switching power supply). If the power output is unstable or without overvoltage protection, if the external power supply voltage fluctuates, it will output unstable voltage and current.
If you are sizing a heat sink, you should use the same luminous efficiency for your calculations. Generally speaking, with the current optical efficiency of 100lm/W, the actual electro-optical efficiency (ie the efficiency of converting electrical energy into light energy) is only about 30%, that is to say, only 30% of the electrical energy is converted into light energy, and the remaining 70% The electrical energy is converted into thermal energy, which must be distributed through a heat sink. For 1W high-voltage LEDs and ordinary low-voltage LEDs with the same light efficiency, the part that generates heat energy is 0.7W, which must be cooled by a cooler. Therefore, with the same input power and drive power efficiency, there is no difference in the size of the heat sink required for this high voltage LED.
LED strips usually have a high voltage of 220 volts, so it is covered with thick flame retardant rubber. Wires and circuit boards are usually made of copper. LED beads confirm no lead. For safety reasons, the service life of LED high pressure lamps must not be inferior, because they are cheap, which may be a safety hazard! Of course, you will find that high-quality products and reasonable prices are not without their problems, but this opportunity is not everywhere! Since high-quality LED technology lamps entered the market, there has been a broad market.
