2. Poor LED Chips

The LED chip quality directly affects brightness, efficiency, and longevity.

Causes:

• Low-cost generic LED chips degrade quickly.
• Inconsistent color temperatures causing poor light output.
• Poor luminous efficiency reducing energy savings.

Solutions:

• Use branded LED chips like Lumileds, Osram, Cree.
• Select chips with high efficiency (≥160lm/W).
• Ensure color consistency with binning control during production.

3. SPD Function (Surge Protection Device)

Power surges can damage LED street lights, leading to sudden failures.

Causes:

• Lightning strikes and voltage spikes from unstable power grids.
• Weak surge protection components.

Solutions:

• Use SPD with 10kV–20kV protection for LED street lights.
