Comparison between COB and traditional LED SMD
November 29, 2023
Want to figure out the difference between COB and SMD LED downlights?
Background: Since LED entered the lighting field, the initial form was that the lamp beads were directly welded on the board, first 3528, 5050, and later 3014, 2835. However, the disadvantages of this method are that there are many processes, including LED packaging and SMT, high cost, and problems such as heat transfer. So COB was introduced into the LED field at this time.
Traditional LED: "LED light source discrete device → MCPCB light source module → LED lamp" is mainly adopted because there is no ready-made suitable core light source component. It is not only labor-consuming and time-consuming, but also costly.
COB LEDs: An Overview
COB, or chip-on-board, LEDs are made by mounting multiple LED chips onto a single board or substrate. This type of LED is becoming increasingly popular in a variety of applications, including downlights. COB LEDs offer a number of advantages over traditional LEDs, including:
SMD LEDs: An Overview
SMD, or surface-mount device, LEDs are made by mounting the LED chips on the surface of a circuit board. This type of LED has been around for longer than COB LEDs and is still widely used in a variety of applications, including downlights. SMD LEDs offer a number of advantages over other types of LEDs, including:
So which type of LED downlight is right for you—COB or SMD?
The answer depends on your needs and preferences. If you’re looking for an LED that is bright and efficient, then a COB LED might be the right choice for you. However, if you’re working with a tight budget, then an SMD LED might be a better option. Whichever type you choose, you can rest assured knowing that you’re getting an energy-efficient and long-lasting light source.
