Is the COB light strip prone to overheating? In-depth analysis of COB light strip heating issues and Jomo Lighting's innovative solutions

In recent years, COB (Chip-on-Board) light strips have become a popular choice for commercial lighting and home decor due to their high brightness, uniform light output, and compact design. However, many users are concerned about one question: Do COB light strips generate excessive heat? As a leading enterprise in the LED lighting industry, Shenzhen Jomo Lighting Technology Co., Ltd. will provide a comprehensive analysis of the causes of heat generation in COB light strips, along with professional solutions, based on technical principles and industry experience.

1. Analysis of Heat Generation in COB Light Strips
(1) High-Density LED Chip Integration
COB technology significantly improves luminous efficiency density by integrating multiple LED chips directly onto a substrate. However, high-power operation within a small area leads to concentrated heat. If the heat dissipation design is inadequate, the surface temperature can rise to 50–70°C.
(2) Circuit Design and Current Control
Some low-quality light strips use inferior driving power supplies or lack constant-current ICs to reduce costs, resulting in excessive current fluctuations that intensify chip heating.
(3) Insufficient Heat Dissipation Structure
Traditional COB light strips rely on passive heat dissipation through flexible substrates (e.g., FPC). Without aluminum channels or thermal conductive adhesive, heat cannot be quickly dissipated.

2. Hazards of Excessive Heat in COB Light Strips
· Accelerated Light Decay: Prolonged high-temperature operation can reduce LED chip efficiency, shortening lifespan by over 30%.
· Safety Risks: In extreme cases, it may cause circuit aging, short circuits, or even fire hazards.
· Installation Limitations: High temperatures may damage illuminated objects (e.g., wooden furniture or acrylic materials).

3. Jomo Lighting’s Heat Dissipation Solutions for COB Light Strips
Addressing industry pain points, Shenzhen Jomo Lighting Technology Co., Ltd. has introduced a "Low-Heat, High-Efficiency" COB light strip series through technological innovation to control heat generation at the source:
