Welcome to Part 2 of our series on designing efficient outdoor car park lighting using Dialux Evo. In this video, we will discuss the step-by-step process of implementing the lighting design we covered in Part 1. From calculating the number of lights required to setting up the lighting layout, we will cover everything you need to know to implement your lighting design successfully. Join us on this journey to create a safe and efficient lighting design for your car park.
In addition to discussing the implementation of the lighting design, we will also explain how to design car park lighting in compliance with the Australian Standards. We will explore the guidelines set by the Australian Standards AS/NZS 1158.3.1 and how to incorporate them into your lighting design. You will learn about the recommended light levels, uniformity ratios, and glare limitations that must be followed to ensure safety and efficiency in your car park. By the end of this video, you will completely understand how to design and implement an outdoor car park lighting system that meets Australian Standards.

Great to see some AS1158 tutorials going up-nice work on the clip! There are a few areas you could refine to improve it further. Here’s some feedback to consider: AS1158.2 outlines the methodology for computer-aided calculations, so here are a few key aspects you missed that can significantly impact establishing compliant values, particularly for vertical illuminance: Vertical Illuminance: The measuring plane is valid up to 7 metres from the extremities of the area under consideration. Horizontal Illuminance: The measuring plane is valid up to 2.5 metres from the extremities of the area under consideration. Maintenance Factor: Include details on how to establish this, factoring in Luminaire Dirt Depreciation (LDD) and Light Source Lumen Depreciation (LLD). Control of Glare and Upward Waste Light: This is addressed in section 3.7 of AS1158.3.1 and includes the Discomfort Glare Index, Limitation of Luminous Intensity (LLI), and Upward Waste Light Ratio (UWLR). The standard doesn’t communicate this well, but these are as relevant to compliance as the illuminance levels. The standard assumes that asymmetric lighting is installed as photometered and without tilt, which is reflected in the equations governing discomfort glare and luminous intensity. Tilting luminaires alters the range of vertical candela angles, shifting peak intensities relative to the observer. For example, with asymmetric lighting, its good practice to specify the luminaire based on the direction and angle required for peak intensity without the need for tilt. Tilting changes this peak, often exceeding the thresholds set by the Discomfort Glare Index and Limitation of Luminous Intensity. In your example, a 10-degree tilt would almost certaintly push intensities above the fixed 65-degree observer angle, exceeding both DGIP and LLI thresholds. To avoid this, a good approach is to reference the 2D polar diagram and adjust the tilt to keep peak intensities as close to the 65-degree line as possible without exceeding it. In my experience, asymmetric fittings leave only 3-5 degrees of flexibility before becoming non-compliant. When i teach this stuff, I i teach tilt at the same time I teach about luminous intensity and in almost all cases, the luminare is designed to be specified as its photometerd, unless its aimable. It’s also worth noting that glare and obtrusive light mitigation are often not well understood but are key to meeting compliance and environmental considerations. Educating others on these aspects-particularly the Discomfort Glare Index, Limitation of Luminous Intensity, and UWLR-can help bridge this gap. If you’d like, I’m happy to walk you through the clacs and methodologies in more detail over a Zoom session-just inbox me. Keep up the good work on these videos!

Thank you for your detailed feedback! I'll definitely make sure to incorporate those points in future videos.

Sir where are u from 😅

Thanks for sharing

Welcome

[@suresh.kmuthu7644]

How can we change the Boom length in this area calculations?.

[@aghabilal4385]

Could you please share the CAD file?

[@ElectricalInfinity]

Thanks for watching, Bilal. Unfortunately, I am unable to share the CAD file with you. However, you can easily find sample car park layouts on various websites for free. Simply Google it! 😀

[@Nugalbags]

Hi, Why do you change tilt angle to -10 degress?

[@yatinthakuryt3362]

How to calculate the load of pole light in exal sheet? Make a video on this. And also about how much load is to be given on which face?

[@lvswitchgearsinfo2.0]

Great♥️

[@travelingupdates9744]

Sir need calculation pole height, distance etc

[@ElectricalInfinity]

I used 8 meter height poles, and the max allowed distance between 2 lights was 45 meters, considering light lumen and height. Please have a look at the light photometry I shared in the video.
