Guangmai Technology is proffesional in making the LED COB 12V 10W USA Bridgelux Chip.
Is it better to use isolated power supply or non-isolated power supply for COB light source lamps?
LED light source (COB light source) which kind of power supply is good? This is a problem frequently encountered by the designers of LED lamps and lanterns. The power supplies used at the moment are divided into isolated and non-isolated power supplies. Now let's compare the isolated power supply and the non-isolated power supply as follows:
It can be seen from the above table that the isolated power supply and the non-isolated power supply have their own strengths and weaknesses. LED light source (COB light source) should be based on the actual power source used for lamps. Export to European and American customers generally requires UL and TUV related safety certifications, and isolated power supplies are the first choice. If cost and efficiency requirements are considered, non-isolated power supplies are preferred for customers who have no requirements on safety regulations. At present, these two power sources will coexist in the market. Due to its small size, competitive cost, and convenient built-in, LED ceiling lamps and downlights currently use more non-isolated power supplies. If safety certification is considered, isolated power supply will be an application driving force.
