What are advantages and disadvantages of constant voltage driving LED Bars?


The constant voltage driving LED Bars have following advantages:

1. In the power range of the adapter, the LED bar could be shortened or lengthened freely as needed.

2. The adapters of constant voltage output  are easier to get and cost-effective.

3. The voltage is fixed like 12V or 24V, and safe.

4. Each LED works independently. Some LEDs' breakdown will not influence other LEDs working.

The constant voltage driving LED Bars have following disadvantages:

1. The constant voltage driving has drop voltage, which means the brightness of LEDs decreases with the decrease of voltage. Usually, after 6m people will start to see a noticeable dimming in brightness due to voltage drop.

2. While there are same power LED and same quality of LEDs, the constant voltage driving LED bar will consume more electric power than the constant current driving LED bar. Because those needed regulating resistors will be loads and consume electric power.

3. The constant voltage driving LED bar work less stably than the constant current driving LED bar. Because the voltage current characteristic of LED is not fixed. While the voltage is fixed, the current still increase with the increasing of temperature. This temperature effect ( increased current due to temperature rise ) will increase by many times.
