The K Series (KS, KM, KL) LED street lights from ZGSM provide a guaranteed 7 years of superior illumination with a minimum total cost of ownership. The roadway luminaires are designed to address the full range of outdoor lighting challenges in municipal lighting, from walkways, bike paths, car parks, residential streets to public roadways. This product family provides an illumination coverage of up to three lanes (and adjacent pedestrian areas) with high uniformity and maximum spacing between columns. The K Series LED luminaires operate at 25, 35, 55, 60, 90, 120, 120, 150, 180 or 200 watts of electrical power with lumen output ranging from 3125 to 26000 lm.
The luminaire consists of a low profile light assembly and an independent electrical chamber in an aerodynamic design for reduced resistance to the wind coefficient. The housing with an integrated, internal heat sink is constructed of high pressure die cast aluminum alloy. The dirt-resistant shape protects the luminaire against dust and foliage buildup and keeps maintenance costs to a minimum. The optical assembly and electrical chamber are sealed against intrusion of water, insects and dust. The light assembly incorporates a micro-membrane breather which provides pressure compensation to prevent seal fatigue and failure. The swing-down, hinged die cast housing underneath which all electrical and optical components are mounted are fixed to the base tray with quick-release latches for tool-less access that make installation and maintenance easy.
The K Series features a thermal design with the shortest possible thermal path and largest possible thermal conduction area. The high thermal conductivity MCPCB is mounted directly onto the die cast aluminum housing, which creates a large contact area to ensure that the heat generated by the LEDs spread and dissipate uniformly and efficiently. Thermal isolation of the electrical and optical components prevent interactive thermal impact.
The K Series LED street lights use LUXEON 3030 2D LEDs which are bundled together in a choice of quantities ranging from 48 to 336 LEDs. These EMC (epoxy molding compound) molded LED packages are workhorse light sources designed for high flux applications with exceptional reliability and excellent lumen maintenance. The LUXEON 3030 2D LEDs mounted onto a metal-clad PCB with high thermal and solder joint reliability. The thermally optimized LED package in combination with robust solder joint performance achieves low thermal resistance along the thermal path between the LED dies and MCPCB. The LED light engines of this product family provide L70 lifetime over 100,000 hours with superior luminous efficacy and chromaticity stability.
Precision engineered optics provide exceptional coverage and uniformity in IES Type I (50°x 160°), Type II (65°x 155°) , and Type III (80°x 160°) asymmetric distribution patterns. State-of-the-art optical control strikes an optimal balance between mast height, fixture spacing, light uniformity and illumination coverage while minimizing light pollution, light trespass and sky glow.
The ZGSM K Series LED luminaires are equipped with Mean Well or Inventronics constant current LED drivers which boast industry leading performance especially in power factor (PF) correction, harmonic performance and efficiency. These LED drivers operated over wide variations in line voltages (100-240V /277V) with built-in protections against overcurrent, short-circuit, overvoltage and over-temperature conditions. The luminaire comes with 10kV / 10kA surge suppression protection to survive lightning strikes and other electrical disturbances. The electrical system includes a safety disconnect to ensure power supply is cut off when the top cover is open.
The dimmable Inventronics LED drivers are available in dimming to 10% with built-in 0-5V, 0-10V and PWM protocols. The street lights may be timer-controlled to deliver dimming schedules for night-time power reduction. The LED driver can be integrated with photocells to provide the daylight harvesting ability for dusk-to-dawn control. The K Series LED street lights can be operated wirelessly through an intelligent roadway lighting management system using the ZigBee protocol.
The luminaire housing is powder coated with a UV stabilized, corrosion resistant TGIC polyester material subsequent to a rigorous cleaning and chemical chromating process. The aluminum housing is chromate conversion coated and electrostatically applied with a thermoset polyester powder coat finish which provides robust protection against impact, UV and salt spray damage. Standard exterior finish color options include light grey and deep grey. Custom RAL colors are available.
The luminaires are provided with die cast fitters that accommodate 60 mm O.D. tenons or arms. Wall mounting brackets and square pole mounting adapters are available.
