40w Led Street Light

Product Introduction

• The core advantage of the 40W LED Street Light lies in its breakthrough performance of "low power, high brightness" achieved through optimized optical design, high-density LED bead layout, and multiple safety protection technologies.
• At a rated power of 40W, the overall luminous efficacy of the lamp reaches 130-140lm/W, with stable luminous flux output at 4800-5200lm, far exceeding the energy efficiency of traditional high-pressure sodium lamps or metal halide lamps.
• Meanwhile, the product has obtained IP65 protection level certification and UL/CE safety certification to ensure long-term stable operation in harsh environments.

Core Parameters

High-Density LED Bead Layout

1.Bead Quantity and Quality

• Uses 36 original LumiLeds 3030 series LED chips, with a single chip luminous efficacy of up to 160lm/W and overall lamp luminous efficacy exceeding 130lm/W.
• Beads adopt dual-chip packaging technology, with a chip size of 3.0mm×3.0mm. Compared with traditional single-chip designs, light intensity is increased by 30%, and service life is extended to over 50,000 hours.
• Bead layout uses asymmetric light distribution design, achieving rectangular spot distribution through a lens array to ensure road surface illuminance uniformity (U0≥0.4) complies with CJJ45-2015 Urban Road Lighting Design Standards.

 

2.Optical System Design

• Light distribution curves are based on non-imaging optics technology, precisely projecting light onto the road surface through secondary optical lenses to reduce light pollution while improving light energy utilization.
• Color temperature is adjustable between 3000K-6500K, with a color rendering index (Ra) ≥80, ensuring true color reproduction of objects during night driving and reducing driver visual fatigue.

Electric Shock Prevention Safety Protection Technology

1.Electrical Safety Design

• The driver power supply supports wide voltage input (AC90-305V) and is equipped with built-in overvoltage, overcurrent, short-circuit, and over-temperature protection modules to automatically cut off the circuit under voltage fluctuations or abnormal operating conditions.
• The lamp body grounding conductor is made of T2 oxygen-free copper with a cross-sectional area ≥2.5mm², and welding processes comply with GB7000.1-2015 standards to ensure grounding resistance ≤0.1Ω.
• The lamp holder features an electric shock prevention structural design, with a distance ≥6mm between internal live components and the outer shell, and insulating materials passing the UL94 V-0 flame retardant grade test.

2.Structural Protection Design

• The lamp body uses a die-cast aluminum alloy shell with surface anodizing treatment, achieving a corrosion resistance grade of WF2, suitable for harsh environments such as salt spray and acid rain.
• The lens is made of PC material with impact resistance reaching IK08 grade, combined with a silicone rubber sealing ring to achieve IP66 protection level, ensuring waterproof and dustproof performance.
• The heat dissipation system adopts a honeycomb heat dissipation structure combined with heat pipe conduction technology, controlling the lamp body surface temperature below 65°C to avoid insulation failure risks caused by high temperatures.
