LED chips

There are several types of LED chips that vary in design, size, light output, and application. The main types of LED chips include SMD LED , COB LED , and chip-on-board LED, but there are also different technologies and formats specific to certain applications.

Here are the main types of LED chips:

1.SMD LED (Surface-Mounted Device LED)

  • What it is : This type of LED chip is mounted on the surface of a printed circuit board using surface-mount technology (SMT) . The chips are compact, small, and have a wide light distribution.
  • Features :
    • Suitable for thin lighting (e.g. LED strips, recessed luminaires).
    • Provides energy efficient lighting .
    • Available in various sizes, such as 5050 , 3528 , and 2835 .
    • Commonly used in decorative lighting , televisions , smart home lighting , and accent lighting .
  • Application : Recessed spotlights, LED strips, LED lamps, TVs, etc.

2. COB LED (Chip-on-Board LED)

  • What it is : A COB LED chip consists of multiple LEDs mounted directly onto a substrate, without being individually packaged. These chips provide intense light output .
  • Features :
    • High lumen output by combining multiple LEDs onto one chip.
    • Ensures better heat dissipation thanks to the design.
    • Typically brighter than SMD LEDs and provides an even light distribution .
    • Often used for spotlights and floodlights .
  • Application : Large area lighting, spotlights, industrial lighting, garden lighting, etc.

3. High Power LED (HP LED)

  • What it is : High-power LEDs are designed for applications requiring high light output . They are often larger than standard LEDs and can handle more energy.
  • Features :
    • Provide a very high light output .
    • Are often cooled by passive or active heat sinks .
    • Suitable for large-scale lighting applications .
  • Application : Outdoor lighting, street lighting, industrial lighting, etc.

4. LAMP LED (LED in Lamp Housing)

  • What it is : These are LED chips built into a lamp housing, making them suitable for direct replacement of traditional bulbs such as incandescent or halogen bulbs.
  • Features :
    • Direct replacement for conventional light sources.
    • Available in different wattages and light colours.
    • Very energy efficient and sustainable.
  • Application : Lamps, street lights, lighting in commercial and residential applications.

5. UV LED (Ultraviolet LED)

  • What it is : These LED chips are designed to emit ultraviolet (UV) radiation instead of visible light.
  • Features :
    • Mostly used for disinfection , drying processes (such as in the printing and coatings industries), and UV lighting .
    • There are different wavelengths of UV LEDs, such as UV-A , UV-B , and UV-C .
  • Application : Water and air purification, curing of gel coatings, medical applications, etc.

6. Micro LED

  • What it is : Micro LED is a technology that uses microscopic LEDs to create displays.
  • Features :
    • They are smaller than SMD LEDs , making them suitable for screens with very high resolutions .
    • They offer high brightness and energetic efficiency .
  • Application : Displays for TVs, smartphones, wearables , and other digital screens .

7. OLED (Organic LED)

  • What it is : OLED is a technology that uses an organic light-emitting layer in the chip to generate light. It's similar to LED, but has a more flexible and thinner design.
  • Features :
    • Provides flexible, thin panels and can be curved or even transparent .
    • High image quality and dynamic contrast .
    • Energy efficient , although they are often less bright than traditional LEDs.
  • Application : TV screens , smartphones , lighting (such as OLED lamps ), and displays .

8. Piranha LED

  • What it is : This type of LED is designed for high power lighting and is often used in applications that require high intensity .
  • Features :
    • Very high light output .
    • Very robust and can handle high currents.
  • Application : Industrial lighting, automotive lighting, and signal lighting.

9. Filament LED

  • What it is : Filament LEDs are designed to look like traditional incandescent bulbs , with LEDs shaped like thin filaments that emit the light.
  • Features :
    • Aesthetically appealing and resembling the incandescent light bulbs used in the past.
    • Offers a warmer light color and optical charm than a traditional incandescent bulb, but is much more efficient.
  • Application : Decorative lighting , lamps , chandeliers , and retro lighting .

Summary of the most popular LED chip types:

  • SMD LED : Compact chips for wide applications, such as strips and recessed lights.
  • COB LED : Multiple LEDs on one surface for high light output and larger applications such as floodlights.
  • High Power LED : For intensive lighting, often used in outdoor lighting.
  • UV LED : For applications that require UV radiation, such as sterilization or curing.
  • Micro-LED : Small chips for high-resolution displays .
  • OLED : Organic LEDs for flexible and thin lighting and display applications.

Conclusion:

The choice of a particular type of LED chip depends on the specific application and required properties, such as light output , energy efficiency , size , and durability . Each type has its advantages and applications, from energy-efficient lighting to advanced display technologies .
