Description

Product Introduction

◎Advantages in color rendering: The 120-watt LED street light has a color rendering index (CRI) ≥85, which can clearly restore the true colors of objects, improve the recognition rate of traffic signs and pedestrian safety. It is significantly better than traditional high-pressure sodium lamps (CRI 20-30) and ordinary LED street lights (CRI 70-80).

◎Electric shock prevention design: The product achieves multiple electrical safety protections through IP65 protection rating, isolated drive power supply, and standardized grounding terminals. It has strong lightning resistance and temperature resistance, and its maintenance safety is much higher than that of traditional street lights.

◎Highlights of core parameters: Luminous efficiency ≥120lm/W, service life ≥50,000 hours, supporting intelligent dimming and light sensing control, with an energy-saving rate of 60%. It is suitable for roads 10-15 meters wide and lamp pole scenarios of 8-12 meters.

Keyword summary: 120-watt LED street light, high color rendering index (CRI≥85), electric shock prevention (IP65), intelligent energy saving, long service life, road safety, modular design, fully enclosed structure.

Color Rendering

The color rendering index (CRI) is a core indicator to measure the ability of a light source to restore the true colors of objects. The 120-watt LED street light achieves the following breakthroughs by using high-color-rendering LED chips (such as Lumileds 3030 or Bridgelux chips with CRI≥85):

Comparison of color restoration capabilities

Light Source Type	Color Rendering Index (CRI)	Color Restoration Effect	Applicable Scenarios
High-pressure sodium lamp	20-30	Object colors are distorted, only light and dark can be distinguished	Traditional road lighting (gradually phased out)
Ordinary LED street light	70-80	Basic color systems can be identified, but saturation is insufficient	General roads, industrial areas
High-color-rendering LED street light	≥85	Close to natural light, can clearly distinguish warning colors such as red, yellow and green	Urban main roads, intersections, school surroundings

Practical value of improved color rendering

◎Traffic safety optimization: High CRI light sources make the colors of reflective films on traffic signs more vivid, extending the driver's recognition distance by more than 30%.

◎Enhanced pedestrian protection: In night walking scenarios, high-color-rendering light sources can clearly show the color of pedestrians' clothes and facial features, reducing collision accidents caused by visual misjudgment. Tests show that after CRI is increased from 70 to 85, the recognition rate of pedestrians is increased by 25%.

◎Urban image upgrading: High-color-rendering lighting makes the road environment closer to daylight, improving the comfort of citizens' night travel, and at the same time enhancing the visual appeal of commercial areas and landscape roads.

Electric Shock Prevention Function

Structural protection design

◎Fully enclosed lamp body: Adopting an integrated die-cast aluminum alloy shell with a silicone sealing ring to achieve IP65 protection rating (dustproof and protection against low-pressure water jet), eliminating the risk of short circuit caused by rainwater or foreign objects intrusion.

◎Insulated drive power supply: Built-in isolated constant current drive power supply, with a voltage difference between input and output terminals ≤36V (Safety Extra Low Voltage SELV standard). Even if a fault occurs inside the lamp body, the shell will not be electrified.

◎Grounding protection device: A grounding terminal is reserved at the bottom of the lamp body, which can be reliably connected to the lamp pole to form a leakage protection circuit. It ensures that the current is introduced into the ground in extreme cases (such as drive power failure) to avoid electric shock accidents.

Comparison of electrical safety standards

Safety Feature	Traditional Street Light (High-Pressure Sodium Lamp)	120-Watt LED Street Light
Electric shock prevention rating	IP53 (basic dustproof, protection against splashing water)	IP65 (completely dustproof, protection against water jet)
Drive power type	Magnetic ballast (including inductive components)	Isolated constant current drive (no inductance)
Grounding requirement	Need additional grounding wire configuration	Standardized grounding terminal for convenient installation
Safety certification	Some products lack international certification	Passed global certifications such as CE/RoHS/UL
