LED and COB lamps are both common lighting sources, and each has its own unique advantages and disadvantages. As for which COB light source or LED light source has a longer life, this requires comprehensive consideration of multiple factors.
The advantages of LED light sources include:
High efficiency and energy saving: LED light sources have high energy conversion efficiency, which is more energy-efficient than traditional light sources.
Long life: Under normal working conditions, the life of LED light sources can reach tens of thousands of hours or even longer, which has a longer service life than traditional light sources.
Wide selection of color temperature: LED can achieve a wide range of color temperature options, from warm white to cool white.
Quick start and dimming: LED lights can light up instantly and support a wide range of dimming.
The disadvantages of LED light sources include:
High initial cost: Compared with traditional light sources, the initial investment cost of LED light sources is higher, but with technological advancement and market competition, the cost is constantly decreasing.
Limited irradiation range: The irradiation range of a single LED light source is relatively small, so multiple LEDs are needed to cover a larger area.
The advantages of COB light sources include:
High integration and uniform illumination: COB light sources achieve high integration of multiple LED chips by directly pasting the chips on the substrate, which can provide higher brightness output and more uniform light distribution.
Color consistency: Since multiple LED chips are used on the same light source, COB light sources usually have good color consistency.
Thermal management: COB light sources usually use metal substrates and have good heat dissipation performance.
The disadvantages of COB light sources include:
Large size: Since multiple LED chips are densely packed on one substrate, the size of COB light sources is relatively large, which is not suitable for some compact space application scenarios.
High initial cost: The manufacturing process of COB light sources is more complicated than that of ordinary LEDs, so the initial cost is higher.
As for which COB light source and LED light source has a longer life, in fact, their lifespan is affected by many factors, including quality, current drive, heat dissipation, etc. Generally speaking, both LED and COB light sources can provide a long service life under normal use conditions, but the specific situation will vary depending on the product quality and use conditions. Therefore, when choosing a light source, it is recommended to refer to the product specifications and life data provided by the manufacturer, and use it reasonably, install it correctly, and maintain it in time to extend the service life of the light source.
