Incandescent Lights

    information to be updated

Incandescent lamps are one of the oldest and most traditional types of lighting, widely recognized for their warm, natural light quality. They work by passing an electric current through a thin tungsten filament inside a glass bulb, which heats up and produces light through incandescence.

The light produced by incandescent lamps is known for its warm color temperature, which creates a cozy and inviting atmosphere. These lamps are often used in residential settings, decorative fixtures, and applications where warm, flattering light is preferred.

Although incandescent bulbs are simple in design and inexpensive to manufacture, they are less energy-efficient compared to modern lighting technologies like LEDs and fluorescent lamps. A significant portion of the electrical energy is converted into heat rather than visible light, resulting in higher electricity consumption and a shorter lifespan.

Incandescent lamps come in various shapes and wattages to suit different needs, from small decorative bulbs to larger general-purpose lamps. They are compatible with most existing lighting fixtures without requiring special equipment.

Despite being largely replaced by more energy-efficient alternatives in many countries, incandescent lamps remain valued for their color rendering and immediate full brightness. They continue to be used in specific applications where these characteristics are important.

Industry knowledge

Incandescent light is a traditional lighting source that produces light by heating a filament with an electric current. The filament is typically made of high-melting-point tungsten, which emits warm, natural light at high temperatures. Incandescent light closely resembles sunlight, offering high color rendering and accurately reproducing object colors, making it suitable for home, restaurant, and artistic lighting. Its simple structure and low cost are advantages, and some models, such as Dimmable Incandescent Bulbs, support dimming functions, allowing for the creation of different atmospheres. Furthermore, decorative Globe Incandescent Lights, with their unique spherical design and soft light, are often used to enhance the aesthetics of a space, combining practicality and decorative appeal.

Incandescent light is one of the more important inventions in the history of human lighting. It provides stable illumination by heating a filament with an electric current. Although the use of incandescent bulbs has decreased with the popularization of energy-saving and LED lights, they still maintain a unique position in certain scenarios due to their natural light color and warm, comfortable lighting effect.

Principles and Characteristics of Incandescent Lights

The core principle of incandescent light is resistive heating. The filament is usually made of tungsten, which has a high melting point and good mechanical strength. When current passes through the filament, its temperature rapidly rises to 2000 to 3000 degrees Celsius, causing the filament to emit visible light. The spectrum of incandescent light is close to natural light, allowing it to present the true colors of objects, making it still popular in photography, art displays, and home lighting.

The main characteristics of incandescent lights include:

  • Natural light color: The light emitted by incandescent bulbs is close to sunlight, with a color temperature usually between 2700K and 3000K, giving a warm and comfortable feeling.
  • High color rendering: Its color rendering index (CRI) is as high as 95 or more, providing good ability to reproduce object colors.
  • Simple structure: The manufacturing process of incandescent bulbs is relatively mature, resulting in low manufacturing costs.
  • Strong dimmability: The light intensity can be changed by adjusting the current, achieving stepless dimming.

Dimmable Incandescent Bulbs utilize this characteristic, adjusting the voltage to change the light intensity, and are widely used in restaurants, living rooms, and other places that require soft lighting.

Classification of Incandescent Lights

Incandescent lights can be divided into various types according to their bulb shape, power, and purpose. Common types include:

  • Standard Incandescent Bulb: The more classic light bulb form, suitable for general household use.
  • Globe Incandescent Light: Spherical design, often used in decorative lighting or fixtures, combining aesthetics and practicality.
  • Reflector Incandescent Bulb: Features a reflector, suitable for focused lighting, such as stage lights and exhibition lights.
  • Dimmable Incandescent Bulb: Allows for brightness control by adjusting the current, suitable for different scene requirements.
