QUICK OVERVIEW

A red 5mm LED (Light Emitting Diode) is a small, solid-state device that emits light when a voltage is applied across its terminals. The LED has a diameter of 5mm, making it compact and suitable for use in a wide range of electronic projects and applications. It typically has a low voltage drop and high brightness, making it an efficient source of light. The LED is often used as a visual indicator in circuits, and can be used in a variety of applications, including displays, lighting, and alarms.

Description

A light-emitting diode (LED) is a two-lead semiconductor light source. It resembles a basic pn-junction diode, which emits light when activated. When a fitting voltage is applied to the leads, electrons are able to recombine with electron holes within the device, releasing energy in the form of photons. This effect is called electroluminescence, and the color of the light (corresponding to the energy of the photon) is determined by the energy band gap of the semiconductor.

Features:

  • 5mm diameter
  • 1.8-2.2V Forward Voltage
  • Max current: 20mA
  • 100+ mcd typical brightness

Blue, Green, Red, White, Yellow

A: LEDs (Light-Emitting Diodes) are semiconductor devices that emit light when an electric current passes through them. They consist of a chip made of a material called a semiconductor, which is surrounded by a transparent plastic lens. When current flows through the chip, electrons and electron holes combine, releasing energy in the form of photons (light). The color of the light emitted depends on the specific materials used in the LED.

A: LEDs offer several advantages over traditional lighting technologies. They are highly energy-efficient, converting a large portion of electrical energy into light. LEDs have a long lifespan compared to incandescent or fluorescent bulbs, reducing the frequency of replacements. They are also more durable and resistant to shock, vibrations, and extreme temperatures. LEDs are available in a variety of colors, offer instant illumination, and can be dimmed or controlled easily. Furthermore, they do not contain harmful substances like mercury.

A: LEDs have found widespread applications in various fields. They are commonly used for general lighting purposes in residential, commercial, and industrial settings. LEDs are used in display screens, such as televisions, computer monitors, and smartphones, due to their high brightness and color accuracy. They are also used in automotive lighting, including headlights, taillights, and interior lighting. LEDs are utilized in signage and advertising displays for their brightness and flexibility. Additionally, they are used in horticulture lighting to promote plant growth, and in medical devices for various applications, such as phototherapy.
