LED diode 3W has become a significant player in the lighting industry due to its high efficiency, long lifespan, and versatile applications. This article aims to provide an in-depth introduction to the 3W LED diode, covering its technical specifications, market trends, and future prospects.

Introduction to LED Diode 3W

LED diodes, or Light Emitting Diodes, are semiconductor devices that emit light when an electric current passes through them. The 3W LED diode is a type of LED that emits light with a power rating of 3 watts. It is widely used in various lighting applications, including residential, commercial, and industrial settings.

Technical Specifications

The 3W LED diode typically features a diameter of around 5mm to 10mm, depending on the manufacturer. It operates at a forward voltage of approximately 3.2V to 3.4V and a forward current of around 350mA to 700mA. The color temperature of the emitted light can range from warm white (2700K to 3000K) to cool white (4000K to 6500K), and even to RGB (red, green, blue) for dynamic lighting effects. The luminous efficiency of a 3W LED diode can reach up to 100 lumens per watt (LPW), which is significantly higher than traditional incandescent bulbs. Additionally, these diodes have a lifespan of up to 50,000 hours, making them a cost-effective and environmentally friendly lighting solution.
