Description

Product Introduction

◎Advantages of bead quantity and quality: The 100W Solar LED Street Light adopts 288 high-power LED beads (CRI≥85, luminous efficiency 155lm/W). Through matrix layout and aviation aluminum substrate heat dissipation design, it achieves a service life of 80,000 hours and a road surface uniformity of 0.72. Compared with traditional street lights, its brightness is increased by 25% and service life is extended by 3 times.

◎Technical breakthrough in color rendering index: The product achieves CRI≥85 (R9≥50) through YAG + nitride phosphor composite coating and spectral continuity optimization. It accurately restores object colors under 5000K color temperature, which is 21% higher than ordinary LEDs (CRI≤70), significantly improving traffic safety and community security.

◎Design for balancing luminous efficiency and color rendering: Adopting CSP chip packaging, optical simulation optimization, and 350mA low-current driving technology, it controls the loss of luminous efficiency within 5% while maintaining CRI≥85, breaking through the technical bottleneck of "10%-15% reduction in luminous efficiency" of traditional high-color-rendering LEDs.

High-Density LED Bead Array

Bead quantity and layout design

The 100W Solar LED Street Light adopts 288 high-power LED beads (0.35W per bead), arranged in a 12×24 matrix on a 6063-T5 aviation aluminum substrate, compared with traditional 100W street lights with 50-100 beads.

◎Uniform light emission: The distance between beads is only 2.5mm. Combined with anodizing treatment on the substrate surface (reflectivity≥90%), it eliminates the "light spots" and "dark areas" of traditional street lights, with road surface illuminance uniformity reaching 0.72 (national standard requires ≥0.4);

◎Heat dissipation efficiency: The aluminum substrate is 8mm thick with a thermal conductivity of 237W/(m·K), matched with 6 8mm heat pipes and a finned radiator (surface area 0.8m²). The junction temperature of the beads is 15℃ lower than that of ordinary designs, and the service life is extended to 80,000 hours (industry average is 50,000 hours);

◎Redundancy design: It supports automatic bypass of a single faulty bead, and the remaining 287 beads can still output 99.6% of the rated power, avoiding the problem of a sudden drop in overall brightness of traditional street lights due to individual bead damage.

Bead quality and performance parameters

◎Luminous efficiency: 160-170lm/W (laboratory data), with mass-produced products stably at 155lm/W, 25% higher than ordinary beads (120-130lm/W);

◎Color temperature: 5000K (pure white light), in line with road lighting standards (EN 13201-3:2016), balancing visual clarity and comfort;

◎Color rendering index: CRI≥85 (Ra≥85, R9≥50), which can truly restore object colors (such as the red of traffic signs and the yellow of warning signs), 21% higher than ordinary street lights (CRI≤70);

◎Anti-sulfuration performance: Using silica gel packaging and silver-plated brackets, passing 1000-hour high-temperature and high-humidity tests at 85℃/85%RH, with a light decay rate of ≤3% (ordinary beads have a light decay of 15% under the same conditions);

◎Drive compatibility: Supporting constant current drive (350mA±5%) with a voltage range of DC 24-36V, adapting to the output characteristics of solar controllers.

Color Rendering Index≥85

Balanced design of color rendering index and luminous efficiency

◎Chip-level packaging: Using Chip Scale Package (CSP) technology, the phosphor is directly coated on the LED chip surface to reduce light reflection loss in the packaging layer;

◎Optical simulation optimization: Simulating light propagation paths through LightTools software and adjusting phosphor distribution density to control luminous efficiency loss within 5%;

◎Drive current control: Setting the bead working current at 350mA (30% lower than the conventional 500mA), reducing the thermal quenching effect of phosphors while maintaining luminous efficiency (luminous efficiency decreases by 1%-2% for every 10℃ increase in temperature).
