5mm LED - Blue 470nm 15 Degree Viewing Angle
This question is about the description of a specific specification of blue LED (Light Emitting Diode). Let's take a look at the main features of this LED:

Size: 5mm
This means that the diameter (or maximum size) of the LED is 5 millimeters. This is the physical size of the LED, which is important for installation and layout design.
Color: Blue
The light emitted by LED is blue. The color of LED is determined by its internal semiconductor material, and blue LED is usually used for various applications such as indicator lights, decorative lights, display screens, etc.
Wavelength: 470nm
Wavelength is a physical property of light, and for blue LEDs, 470 nanometers (nm) is a common wavelength value. This value determines the color purity of light and is important for applications that require precise color matching, such as display screens.
Perspective: 15 degrees
Perspective refers to the maximum angle range that light can directly reach when an LED emits light. A 15 degree viewing angle means that LED light is mainly concentrated within a relatively narrow range, which is useful for applications that require directional lighting such as stage lighting and spotlights. However, this also means that when viewed from a larger angle, the brightness of the LED will significantly decrease.
In summary, this 5mm blue LED has a wavelength of 470nm and a viewing angle of 15 degrees, making it suitable for applications that require precise color matching and directional lighting. Its small size makes it easy to install and use in various devices.
