LEDs come in various designs and dimensions. The color of the plastic lens often aligns with the light emitted, though this is not always the case. For example, purple plastic is commonly associated with infrared LEDs, while many blue LEDs feature clear housings. Contemporary high-power LEDs utilized for illumination typically are found in surface-mount device (SMD) packages. Additionally, certain LEDs can have diffused lenses.
Basic LED
The basic LED is among the most commonly utilized types. Due to its widespread use, it is relatively affordable compared to other LED varieties. Its design is straightforward and functional.
Dome LED
This LED variant features a dome shape that enhances the area from which light is emitted. In other words, the light's emission angle is broader than that of basic LEDs. The specification sheets nearly always include a “half-power angle,” marking the angle at which brightness is halved. If a wider emission angle is desired, one can carefully trim the dome using a Dremel tool. Caution is advised to ensure you don't damage the delicate wiring within.
SMD LED
SMD LEDs are typically compact in size, with “SMD” indicating “Surface Mounted Device.” As suggested by the name, these LEDs are soldered onto the PCB surface rather than through conventional holes. They are usually attached by precision machines (soldering robots) and can be complicated to solder manually, although it is not impossible. For manual soldering, a fine-tipped soldering iron, thin solder, adequate lighting, magnification, and skilled hands are essential.

Display LED
This type of LED is primarily utilized in display applications due to its flat design.
Values for SMD Resistors for LED Lighting
Some Simple Arithmetic
Calculating the voltage drop across the LED is the first critical step. This varies by color—white and blue LEDs have a drop of approximately 3 volts, greens and yellows about 2 volts, and reds around 1.6 volts. Therefore, when interfacing with an HO or N decoder supplying about 13 volts, 10 volts will need to be dropped across the series resistor when using white LEDs.
Determining Resistor Values
It’s common for LEDs to require around 10 mA of current to achieve adequate brightness. The series resistor value can be calculated using the formula: Voltage across resistor (10 volts) / Current (10 mA or 0.01 A). This results in a value of 1,000 ohms (1 Kohm). Should you need enhanced brightness, simply reduce the resistor value (for example, to 500 ohms), or double it to decrease current to half (5 mA).
Power Ratings
To determine the resistor's power rating, utilize the formula: voltage squared / resistor value. For instance, a 10-volt drop across the resistor yields a power dissipation of (10 x 10) / 1,000 = 0.1 watt, sufficient for a 1/8 watt resistor. For a 470-ohm resistor, the estimated power will be almost double, requiring at least a 1/4 watt rated component.
