Description

Product Introduction

◎High-color-rendering lighting technology: The 250W Solar Street Light adopts quantum dot phosphors and a five-chip light-mixing design to achieve a CRI≥85, significantly improving the face recognition rate (95%) and traffic sign recognition distance (65 meters). At the same time, it reaches a luminous efficiency of 160lm/W, balancing color reproduction and energy-saving requirements.

◎Class II electric shock protection system: Through double insulation (basic insulation + supplementary insulation), IP66 protection, and a 60V safe voltage design, the leakage current is reduced to 0.2mA (only 1/600 of traditional street lights), completely eliminating the risk of electric shock, and verified by a 1500V high-voltage impact test.

Color Rendering Index 85

The 250W Solar Street Light achieves a CRI≥85 through "quantum dot phosphor + multi-chip integration" technology, while reaching a luminous efficiency of 160lm/W (total luminous flux of 40,000lm).

◎Quantum dot phosphors: Using CdSe/ZnS core-shell quantum dots, the emission wavelength is precisely regulated through the quantum confinement effect. The proportion of red light (620-650nm) is increased to 25% (1.5 times that of ordinary LEDs), significantly improving the reproduction of skin tones and traffic signs;

◎Five-chip light-mixing design: Integrating five-color chips of blue light (450nm) + green light (525nm) + yellow light (590nm) + red light (630nm) + amber light (585nm), which are mixed through optical lenses to achieve full-spectrum coverage (400-700nm);

◎Intelligent color temperature adjustment: Supports stepless dimming from 2700K to 6500K, automatically switching to 3000K warm light in the early morning/dusk (to reduce glare) and maintaining 5000K neutral light at night (to improve visibility).

Class II Electric Shock Protection Design

The 250W Solar Street Light adopts triple protection of "Class II double insulation + IP66 protection + safe voltage" to achieve zero risk of electric shock.

Class II double insulation

◎Basic insulation: A 1.5mm thick flame-retardant PC shell (withstand voltage 4000V) is used between the LED driver power supply and the lamp pole;

◎Supplementary insulation: A 0.8mm thick silicone sleeve (withstand voltage 2000V) is added outside the basic insulation to form a double barrier;

◎Test standard: Passes the 1500V high-voltage impact test of IEC 60598-1 (no breakdown for 1 minute);

IP66 protection rating

◎Dustproof: Completely prevents dust ingress (IP6X), avoiding short circuits caused by the accumulation of conductive dust;

◎Waterproof: Withstands immersion in 1-meter deep water for 1 hour (IPX6), preventing rainwater from penetrating into live components;

Safe voltage design

◎Solar power supply: The system voltage is ≤60V DC (1/4 of the mains voltage), so even if the human body comes into contact, it will not cause a fatal current;

◎Overvoltage protection: Equipped with a TVS diode to clamp the voltage within 72V, avoiding voltage surges caused by lightning strikes or battery overcharging.
