The power of different LED strips is different, so the power of the matching power supply should be carefully selected. Here is a list of the power of the LED strip:
0603LED light bar: 12V, 60 LEDs per meter, 1.5W per meter;
1210LED light bar: 12V, 60 LEDs per meter, 4.8W per meter;
5050LED light bar: 12V, 30 LEDs per meter, 7.2W per meter;
5050LED light bar: 12V, 60 LEDs per meter, 14.4W per meter of power;
For example, if you buy a 5050 LED light bar, the matching power supply is 12V, 4A specifications, then one power supply can only have 6 meters 5050 LED light bar. Because the power of the 5050 LED strip is 7.2W per meter, the total power of 6 meters is 43.2W, and the rated power of the power supply is 48W. It is generally not recommended to use the power supply at full load, because that has a great impact on the life of the power supply. It is recommended to use only the power supply. 95%. If you need 100 meters, the corresponding 4A power supply needs to be equipped with a minimum of 16.
Speakers are one of the most common output devices used with computer systems. Some speakers are designed to work specifically with computers, while others can be hooked up to any type of sound system. Regardless of their design, the purpose of speakers is to produce audio output that can be heard by the listener.
Speakers are transducers that convert electromagnetic waves into sound waves. The speakers receive audio input from a device such as a computer or an audio receiver. This input may be either in analog or digital form. Analog speakers simply amplify the analog electromagnetic waves into sound waves. Since sound waves are produced in analog form, digital speakers must first convert the digital input to an analog signal, then generate the sound waves.
The sound produced by speakers is defined by frequency and amplitude. The frequency determines how high or low the pitch of the sound is. For example, a soprano singer's voice produces high frequency sound waves, while a bass guitar or kick drum generates sounds in the low frequency range. A Speaker System's ability to accurately reproduce sound frequencies is a good indicator of how clear the audio will be. Many speakers include multiple Speaker cones for different frequency ranges, which helps produce more accurate sounds for each range. Two-way speakers typically have a tweeter and a mid-range speaker, while three-way speakers have a tweeter, mid-range speaker, and subwoofer.
