Lighting systems have evolved over time and moved away from high energy consuming filament bulbs to halogen bulbs to LED lighting systems. LEDs are diodes that emit light. Hence, they are consider as a type of lighting technology which are long-lasting and consume less energy. LED light systems are known to use only 15% of energy in comparison to standard halogen bulb uses. Hence, there is a lot of interest in knowing how a LED light circuit board works and the role of 2835 SMD LED.
What is a LED Light Circuit Board?
An LED light circuit board is a printed circuit board (PCB) that is the base or the mechanical support for electrical connections and LEDs. In an LED when an electric current passes through it, the holes from p-type semiconductors recombine with electrons from n-type semiconductors to produce light. In some cases, LEDs are use to detect weak electric currents in circuits.
What is 2835 SMD LED?
2835 SMD LEDs are consider as a type of LED package used in LED strips and lighting applications. The digits 2835 is the physical size of the package, and measure 2.8mm x 3.5mm. The compactness of these LEDs and flexibility ensure these LEDs are used in multiple lighting applications. They exhibit luminous efficacy, have low power consumption and have a wide-beam angle for easy packaging.
2835 LEDs are more energy efficient and brighter in comparison to SMD 3285. They are also practically more efficient as compared to 5050 SMD. The 2835 LED variant produces about 20 percent more light while drawing less power. 2835 LEDs are optimal for applications where high efficacy and smooth appearance are critical, such as troffers, high bay fixtures, or panel lights.
They consume power in the range of 0.2W, 0.5W, or 1W. The voltage of an 2835 LED SMD varies around 2.8 to 3.4 volts, depending on the specific model and manufacturer.
As a result, 2835 LEDs are popular for their brightness as well as energy efficiency. They are commonly used in applications that need a light in small spaces like backlighting for displays.
How to make a LED light circuit board?
Making a LED light circuit board is simple as the components needed are available easily. To create a functional lighting device, a series of LEDs are solder into a PCB. The LED circuit consists of these LEDs with the flow of current from anode to the cathode.
Here are some steps for making an LED light circuit board:
- Design the LED PCB with a circuit diagram.
- Transfer the design to the board
- Etch the board
- Drill holes
- Solder the components
- Connect the positive terminal of the battery to one terminal of the switch
- Connect the other terminal of the switch to the longer leg of the LED
- Connect the shorter leg of the LED to the negative terminal of the battery
- Test the LED PCB
What is the future of LED lights and LED Light Circuit Board?
The use of LED lights is already a global practice. It is expect that soon these lights can be remotely controlled and save energy when lights are not need. It is expect to supersede all types of lighting systems in the coming years. LED lights on 2835 SMD LED and more advanced boards are use in creating lights in multiple colors to stream music, notify data or alerts, and generate white light without the need for a phosphor coating. The cost of LEDs is also expect to drop dramatically and consume less energy for longer life. The average lifespan of an LED light is 50,000 hours.
