1.The importance of voltage selection
(1)Choosing the appropriate voltage is crucial to the performance and life of the LED strip. Voltage mismatch may cause the light strip to fail to emit light normally. For example, if the voltage is too low, the light strip will be dim or unable to light up. If the voltage is too high, the light strip may be too bright, causing the chip to overheat, shorten its life or be damaged.
(2) Mismatched voltage may also interfere with the normal function of the controller, because the controller is designed based on the rated voltage of the light strip. Wrong voltage will prevent the controller from adjusting the brightness and color of the light strip.
2. Common voltages
(1) DC12V: For scenes such as display cabinet lighting and counter lighting, 12V LED light strips are a good choice. Because these scenes usually do not require a particularly long length of light strip, a 12V light strip can provide sufficient brightness when used with a 12V DC adapter. In addition, in indoor environments, the 12V voltage is relatively safe and easy to install and use.
(2)DC24V: In commercial lighting scenarios, if longer light strip length and higher power are required, 24V LED light strips are more suitable. For example, in the shelf lighting of shopping malls or the decorative lighting of store facades, the 24V DC adapter can provide stable power for longer light strips to ensure sufficient brightness output. Compared with 12V light strips, at the same power, 24V The current of the light strip is smaller, and thinner wires can be used during wiring, reducing costs.
(3)DC5V: 5V LED light strips are very suitable around some small devices powered by USB interfaces, such as the interior decoration of computer cases or the lighting of small electronic devices. They can be powered directly by a USB power adapter or USB mobile power supply, using the universal 5V voltage output of the USB interface, which is very convenient.
(4)DC36V or 48V: For landscape lighting and high-power outdoor lighting of large buildings, 36V or 48V high-power LED light strips can meet the needs. These high-voltage light strips can provide enough power to illuminate large-area building facades or outdoor landscape areas, such as large square sculpture lighting, building outline lighting, etc.
(5)AC110V or 220V: In some large-scale engineering lighting projects, such as the overall lighting of large bridges and high-rise buildings, 110V or 220V high-voltage light strips will be used. Since these light strips are usually installed in high positions or out of reach of people, 110V or 220V high voltage can reduce line losses and provide enough power to achieve long-distance, large-area lighting effects.
3. How to determine the appropriate voltage
(1) First, be sure to read the product manual carefully. The product manual will clearly give the operating voltage and power requirements of the LED light strip. This is the most basic basis for choosing the appropriate voltage.
(2)Secondly, consider the length and power requirements of the light strip. If you need a longer strip or higher power output, you may need to choose a higher voltage strip, such as moving from 12V to 24V or higher. At the same time, the power supply situation should also be considered. If there is only USB power supply, then a 5V light strip may be the only choice; if there is a power supply device such as a 12V DC adapter or a 24V DC adapter, you can choose between 12V and 24V according to the length of the light strip and power requirements.
(3) Finally, for some special application scenarios, such as outdoor high-power lighting or engineering lighting, the appropriate voltage must be selected based on various factors such as installation location, safety requirements, and lighting effects. For example, in a humid outdoor environment, to ensure electrical safety, you may need to select power supplies and light strips with appropriate protection levels, and determine the appropriate voltage based on power requirements to avoid safety hazards such as leakage.
