Why this type of led street light become popular recent 2 years?













If you often pay attention to led street light, you will find such design of led street light is more or more popular in the market? Why? Let me sum up some points based on my experience as below, wish it will be helpful for your current or next project for choosing led street light.



Structure
This type of led street light is designed with an independent electrical chamber in an aerodynamic design and slim shape appearance for reducing resistance to the wind coefficient. The housing 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.
Thermal Design
The thermal design for this led street light 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.
Light Source
This type of LED street lights use LUXEON 3030 2D LEDs as light source. The 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.
Heart--LED Driver
LED Street lights are equipped with Mean Well 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.
Optic
Precision engineered optics provide exceptional coverage and uniformity in 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. What’s more, with tempered glass outside, it will be more convenient to do maintenance for cleaning.
Adapter
The adapter of this type of led street light can be installed both horizontal way or vertical way, so it can be matched most of the poles.
