This means that the light source is either COB or SMD. These are two terms for products that do not have a replaceable/changeable light source.
- What is COB?
Chip-on-board technology is that which involves mounting an LED chip in direct contact with the material to produce LED arrays.
Due to the small size of the LED chip, Chip-on-Board technology provides a much higher packing density than surface mount technology. This results in higher intensity and greater uniformity of light for the user.
- The advantages of COB:
Compactness due to the small size of the chip
High intensity, especially at short distances
High light uniformity, even at short working distances
Superior thermal performance for better lifetime, stability and reliability
- What is SMD?
Surface Mounted Device LEDs are the most common LEDs on the market today. The LED chip is permanently mounted on a PCB. The SMD LED chips come in different sizes with different light outputs. You have several names for the SMD LED Chips related to their dimensions. SMD chips are also known as bright. They can produce 50 to 100 lumens per watt.
- De voordelen van SMD:
The wider beam angle produced by SMD LEDs is less directional, making it more suitable for various applications, including spotlight, floodlight and general lighting.
