What are the advantages and disadvantages of LED filament bulbs that are gradually emerging in the market compared with energy-saving lamps and incandescent lamps? The Guangdong Provincial Quality Supervision Bureau recently released the first quarter LED lighting product quality analysis report shows that compared with incandescent lamps and energy-saving lamps, led bulbs are safer and more energy efficient, but still have a higher room for improvement in color rendering index.

Led bulb manufacturers said that compared with incandescent lamps, energy-saving lamps, led bulbs are more secure. This is because the power consumption of a single LED is very low, and the power consumed by a high-power LED generally does not exceed 1 W. The requirements for conductive lines are not high, and short-circuit faults caused by line aging are less likely to occur. Moreover, the led bulb is completely encapsulated in the epoxy resin. It is stronger than the bulb and the fluorescent tube, and there is no loose part in the lamp body. These characteristics make the led bulb difficult to be broken and damaged.

In addition, the LED light source is a low-voltage microelectronic product, and the working voltage of the LED is 2-3.6V, which is an extremely low safety voltage, and there is no electric shock accident when the light source is replaced. Since the LED bulb is a cold light source, there is no possibility of burns caused by incandescent lamps and high surface temperatures of the gas discharge lamp.
