Description

Product Introduction

◎High-density lamp beads + high-power driver: The power of a single lamp bead reaches 1.5-3W, with a total power of 60W and a luminous flux exceeding 6000 lumens, which is 100% brighter than traditional 30W street lights;

◎Intelligent light control + long battery life: Equipped with an MPPT solar controller and a lithium iron phosphate battery, it can last for 5-7 days in cloudy and rainy weather, with zero electricity bills throughout the year;

◎Modular quick-install design: No professional tools are required, and installation and commissioning can be completed within 30 minutes. It is compatible with 4-12 meter lamp poles and flexibly covers scenarios such as roads, squares, and parking lots.

High-Density LED Lamp Beads

New-Generation Lamp Bead Technical Architecture

The new-generation Solar Street Light 6000 Lumens achieves a performance leap through the following technical combinations:

1.36-48 High-Power LED Lamp Beads: Total Luminous Flux Exceeds 6000 Lumens

High-power lamp beads from Bridgelux (USA) or Epistar (Taiwan) are selected, with a single bead power of 1.5-3W and luminous efficiency of 150-180lm/W. Taking the 48-bead solution as an example:

◎Theoretical luminous flux: 48 beads × 3W × 180lm/W = 25,920lm (after a driver efficiency of 95%, the actual luminous flux reaches 24,624lm);

◎Actual luminous flux: After concentrating light through optical lenses, the effective luminous flux on the road surface reaches 6000lm (covering scenarios with 8-meter lamp poles and 20-meter spacing), which is 25% brighter than traditional 30W street lights (4800lm).

◎Measured data: In a project at an industrial park in Hangzhou, the illuminance of the new-generation street lights reaches 30lux (national standard requires ≥20lux), while traditional street lights only reach 22lux, and the nighttime accident rate has decreased by 15% year-on-year.

2.Ceramic Substrate + Gold Wire Packaging: Service Life Exceeds 100,000 Hours

The bottom of the lamp beads uses an aluminum nitride ceramic substrate (thermal conductivity 170W/m·K), combined with 99.99% pure gold wire bonding, reducing the thermal resistance from 3℃/W in traditional solutions to 0.6℃/W. Laboratory accelerated aging tests show:

◎Junction temperature control: At an ambient temperature of 85℃, the junction temperature remains stable below 80℃ (far lower than the LED chip safety threshold of 125℃);

◎Service life prediction: Calculated according to the LM-80 standard, the service life of the lamp beads reaches 100,000 hours under the TM-21 model (based on 12 hours of daily use, it can last 22 years);

◎Light decay curve: The light decay rate is only 5% after 10,000 hours, and ≤15% after 50,000 hours, which is far better than the industry average (30%-50%).

3.Intelligent Temperature-Controlled Driver Circuit

The system is equipped with a built-in temperature sensor and constant current driver chip, which monitors the lamp bead temperature in real time and automatically adjusts the output current:

◎High-temperature protection: When the junction temperature ≥100℃, the current drops to 80% of the rated value to prevent overheating damage;

◎Low-temperature compensation: When the ambient temperature ≤-20℃, the current increases to 110% of the rated value to ensure low-temperature startup performance.

Comparison of Lamp Bead Performance

Lamp Bead Type	Single Bead Power (W)	Total Luminous Flux (lm)	100,000-Hour Light Decay Rate	Service Life (hours)	Single Bead Cost (yuan)
Ordinary Low-Power Beads	0.5-1	4800-5400	35%	50,000	0.8
High-Power High-Density Beads	1.5-3	6000+	8%	100,000	2.5

High-Power Solar Panels and Batteries

New-Generation Energy System: 70-100W Monocrystalline Silicon Panels + Lithium Iron Phosphate Batteries

◎70-100W Monocrystalline Silicon Solar Panel

Monocrystalline silicon panels with 23% conversion efficiency (size 1.6m×1m) are selected, with power generation 28% higher than traditional polycrystalline silicon panels (18% efficiency).

◎ MPPT Solar Controller: Charging Efficiency Increased to 98%

The charging efficiency of traditional PWM controllers is only 75%, while MPPT controllers increase the efficiency to 98% by dynamically adjusting the voltage-current ratio. Taking a 100W solar panel as an example:

PWM controller output: 100W × 75% = 75W;

MPPT controller output: 100W × 98% = 98W, generating 23Wh more electricity per day and extending the battery life by 1 day in cloudy and rainy weather.
