Tianyi Series 30w/50w Solar Street Light

Top vertical heat sink fins increase the natural convection heat dissipation area, keeping LED  junction temperature more effectively controlled during high-temperature seasons
50W 50W specification balances medium road width and battery life requirements in this series, making it the appropriate power for township main streets
Sturdy mounting ear brackets on both sides of the lamp body for stable pole connection, adapting to long-term vibration environments
Built-in waterproof breathable valve balances the pressure difference inside and outside the lamp body, reducing seal failure caused by thermal expansion and contraction
LED Driver power supply uses wide-voltage input design; stable light source driving even when battery output voltage fluctuates

Top Fin Heat Dissipation, Suitable for High-Temperature Regions
Summer high temperatures in southern China are one of the main causes of early LED light decay in solar street lights. The Tianyi series top fin heat dissipation design has longer LED LED  lifespan performance than finless models in high-temperature and high-humidity regions of South and Southwest China.

Waterproof Breathable Valve Reduces Seal Aging
The waterproof breathable valve allows gas exchange between the inside and outside of the lamp body while preventing moisture entry, effectively relieving the pressure difference caused by temperature differentials, delaying seal ring aging, and reducing the risk of water intrusion into the lamp.

30W/50W Fills the Power Gap for Township Roads
The common 30W and 50W  option commonly seen between 40W  in the market is slightly more expensive; the Tianyi series at 50W  directly meets this power segment requirement in a more practical power coverage approach.

Q1: Will the top heat sink fins accumulate dust? Does excessive dust affect heat dissipation?
A: The fins are vertically designed; natural dust mainly accumulates on the top flat surface with limited dust in the fin gaps. Annual cleaning is recommended (synchronized with PV panel cleaning) using a brush for sweeping, which does not affect normal use.

Q2：Tianyi series 50W replace the 30W  metal halide lamp in grid-powered street lights?
A: It can be used as a reference, but not a simple power-to-power comparison. Calculation based on actual road surface illuminance requirements is recommended. Tianyi series 50W At 6m  installation height, the road surface illuminance can typically meet or exceed that of the 30W  metal halide lamp.

Q3: Does the waterproof breathable valve require regular maintenance?
A: The breathable valve is a maintenance-free design requiring no special maintenance under normal use. If obvious moisture condensation is found inside the lamp body, check if the breathable valve is blocked; rinsing the outside of the valve with clean water will restore normal operation.
