There are two common LED lamp power drive devices: one is external and the other is internal.
The external power supply is to install the power supply outside, mainly used in ceiling lights, panel lights, floodlights, downlights, high bay lights, street lights, etc. There are two types of external power supplies, one is waterproof, which is mainly used outdoors, and the other is non-waterproof, which is mainly used indoors.
The built-in power supply is to install the power supply in the lamp, which is mainly used in bulb lights, spotlights, candle lights, PAR lights, etc.
Features of external power supply; simple installation, easy to replace, reduce heating of LED lamp beads, and effectively reduce light decay.
Features of built-in power supply; complex installation, but beautiful, increase the heating of the LED lamp beads, and increase the service life of the LED with small light attenuation.
At the same time that the LED color guides, the life and reliability of the LED drive power directly affect the long life of the LED Garden Lights. Therefore, while the LED industry chain continues to integrate and develop, the maturity of the LED drive power technology plays a decisive factor. Affecting the use of LED lighting products is because the life of the LED driving power supply itself directly drags down the life of the LED lighting, or the low efficiency of the driving power leads to low efficiency conversion of the LED lighting, or the unstable output affects the luminous quality.
In the future, LED drive power will develop towards the trend of stability, safety, high efficiency, no electrolytic capacitor, highly integrated and small size, and the use of electrolytic capacitor-free LED driver will become the market choice.
