LEDs - Spacers, Standoffs

Light emitting diodes, or LEDs, are small, light weight electronics components that create a small, but powerful light source. LEDs are divided into two main types: spacers and standoffs. Each type of LED has different applications and working principles that make them effective options for specific lighting applications.

Spacer LEDs

Spacer LEDs are devices that use a special adhesive to act as a spacer on a PCB, or printed circuit board. This type of LED is most commonly used for providing localized light within a specific area, such as in a small office or a retail store. Spacer LEDs usually use very small amounts of power and require very few components, making them a cost-effective option.

The basic working principle for spacer LEDs is simple. A small, white LED diode is encased in a transparent epoxy casing that is designed to spread and evenly distribute the light in a specified area. The LED is then connected to a power source and when subjected to voltage, a current flows through the LED and the light is emitted.

Standoff LEDs

Standoff LEDs are devices that are used to provide greater directional control of light. They are commonly used in applications such as accent lighting, security lighting, or task lighting. Standoff LEDs use larger amounts of power and require more components than the average spacer LEDs, but the result is a powerful directional light that can be designed for a myriad of applications.

The working principle for standoff LEDs is similar to that of spacer LEDs. A large, white LED diode is encased in a transparent epoxy shell, however, in this case, the shape of the epoxy shell determines the directing of the light emitted. This is done by designing curved, or angled surfaces on the epoxy shell that cause the light to reflect and refract in certain directions. This enables architects and designers to provide creative and complex lighting solutions that highlight and illuminate certain features in a room or outdoor area.

Conclusion

Understanding the differences between spacers and standoffs is crucial in order to choose the most suitable LED for any given application. Spacers are typically used to provide a small localized light without much directional control, while standoffs are used for larger, more powerful and directional light sources. Both types of LEDs use the same basic principle of voltage current flow through white LED diodes encased in epoxy casings, however the end results are different and depend on the application for which the LEDs will be used.
