Which Type of LED Has the Longest Lifespan?
The lifespan of an LED can vary greatly depending on the type of LED chip used, as well as external factors such as material quality, heat dissipation, and the usage environment. Below we explain the main which type of LED has a longer lifespan, their characteristics, and advantages.
Types of LEDs and Their Lifespan
DIP LED Chip (Dual In-line Package)
DIP LEDs have the chip encapsulated in a plastic casing with two legs for connection. They are more robust but less efficient at heat dissipation, which can shorten their lifespan.
Lifespan: Between 20,000 and 50,000 hours.
SMD LED Chip (Surface-Mount Device)
These are the most common LEDs in current lighting fixtures. These chips are mounted directly on the surface of the circuit board. Thanks to their compact design and often being placed on aluminum heat sinks, they offer better thermal management.
Lifespan: Between 35,000 and 60,000 hours, depending on quality and conditions.
COB LED Chip (Chip On Board)
These LEDs group several small chips in a single module, which improves light uniformity and heat dissipation. COB LEDs offer high power and high thermal efficiency, resulting in a prolonged lifespan.
Lifespan: Between 50,000 and 70,000 hours.
MicroLED
A more advanced technology using tiny chips with high efficiency and very low heat generation. Although still in development for mass applications, they promise lifespans exceeding 100,000 hours and excellent light quality. Currently, their use is more common in displays than in general lighting.
Lifespan: Over 100,000 hours
Summary Table: Approximate Lifespan by LED Type
| LED Type | Description | Estimated Lifespan (hours) | Common Applications |
|---|---|---|---|
| DIP | Encapsulated chip with legs | 20,000 - 50,000 | Indicators, signage |
| SMD | Surface-mounted chip | 35,000 - 60,000 | General lighting, decoration |
| COB | Multiple chips in one module | 50,000 - 70,000 | Powerful and uniform lighting |
| MicroLED | Very small chips, high efficiency | >100,000 (in development) | Displays, future lighting |
COB and MicroLED generally offer the longest lifespan due to their efficiency and better heat management. However, the actual lifespan will also depend on product quality and how the fixture is installed and used.
