Understanding Photometry Curves of Light

[@rawalmadan1945]

👏good explanation and simple understanding of a complex looking LDC's that normally difficult to interpret for non lighting people

[@SumaiyaEliyaz]

Thank you! I’m glad the explanation made the complexities of LDCs easier to grasp. Simplifying technical concepts so they’re accessible to everyone is always the goal!

[@sagarpaul6871]

you made this so easy to understand! I searched so many in Google over past few years, but hardly got this clear explanation. Love & Respect for you..

[@SumaiyaEliyaz]

Thank you so much for your thoughtful comment! 🙏 Yes, it did take quite a bit of research to simplify the topic of photometric curves and present it in an easy-to-understand way. Honestly, making these videos takes a lot of time and effort, so it truly means a lot when it's appreciated. I'm glad it helped! 😊

The best video I have seen to explain the c gamma plane. Thank you Very Much.

Thank you so much for your kind words! I'm pleased to hear that you found the explanation helpful. Keep supporting the channel it helps us in creating more insightful videos.

Wonderful video Ma'am learned a lot of polar curve, beam angle and intensity of light thanks ma'am

Your videos are excellent, and I’ve watched all of them! Could you please make a video on the best way to align floors? Specifically, I’d like to know how to determine the correct placement of the first floor on the ground floor etc. Additionally, could you explain how to ensure that lighting calculations are accurate, including how to analyze the results and approach improvements? Thank you!

[@SumaiyaEliyaz]

Thank you, glad to know you have watched all the videos on channels. 😊 For aligning 2 storey use staircase or lift as reference, as only this will not change irrespective of the storey. Regarding accurate lighting calculations and reports.. It's on my list to make next tutorial. Thank you, keep supporting the channel. It helps us bring more videos.

[@Yasir-q9o]

Thank you for the explanation. I'm trying to figure out how to choose the right lighting for a specific area. The process seems to involve selecting a light, evaluating its effectiveness, and possibly adjusting its position. I think this has to do with interpreting the lux levels on a plane, but I'm not entirely sure. Could you explain this in the simplest way possible? I would really appreciate it. Also, if you need any help with improving your KZbin channel or website or any other content, let me know. I’m happy to help for free.i have access to premium tools and i think i can help if you needed. thanks

@@Yasir-q9o thats nice of you to help , I will surely get in touch on this but not for foc. coming to topic you need to understand I can make tutorial on it but it would take some time. Or we can discuss this if you take one on one session though my company NOVA. I provide paid Dialux Evo workshops, but since you need only this topic, we can discuss it .If intrested pls connect at [e-mail]

[@nihalnajeem9195]

Great video, i am also learning many tips and tricks from your videos. Have one suggestion, for easy understanding / for beginners you could have included how IES files are made ,what exactly is the blue and red line and how we get them. Circular lines also reference for Intensity in cd.

[@SumaiyaEliyaz]

@@nihalnajeem9195 I mentioned that it's a graphical representation of light output from luminarie. And the Red indication is for c0-180 I can't include in same video how IES files are made it's different topic.

[@salonigupta6570]

Hii, i'm loving you video. And watching all video playlists viz. Please explain maintenance factor, power loss factor and reflection factor in dialux what is the use and why it's needed in dialux.

[@SumaiyaEliyaz]

Thank you dear.. I am noting this topics on my list for KZbin tutorial

[@Omegito]

Hi Eliyaz, thanks for the very clear video. Very useful! I have a question about it: LED strips have photometrics at 306°. If I use them for indirect lighting, they might work well, but I have doubts when I use them for direct lighting. Specifically, shouldn't the photometrics of the LED strip lights change depending on the opal and the aluminum profile they are inserted into? For example, if I place the strip in a low and wide aluminum profile, the photometrics should be wider compared to if I insert it in a deep and narrow profile, right? How do you manage the lights that you need to insert into aluminum profiles to have reliable photometrics?

[@SumaiyaEliyaz]

Thank you and glad you found the video helpful, btw you can call me by my first name. And coming to your question... Your question already has the answer. In actual installations, you use LED strip lights with profiles. But in Dialux, you only use the IES files of the LED strips, so the profiles are missing. That's why using wider optics IES files won't work well. To fix this, you should create a profile with an extrusion volume in Dialux to replicate the real-time profile and check the output.

[@klmkt4339]

In both cases the acrylic sheet acts as a source of light. The depth of the profile only slightly affects the beam angle.

Very Informative video. Can I suggest to make similar video for topic-Chromaticity tolerance -initial MacAdam.

thank you, and noted the topic 🙏🏻

Hi I have been working in lighting co for 1 year now I want to expand my knowledge and learn the dialux to be able to read the ies files place the lights in proportion to the area and decide the fixture according to the lux level both for indoor and outdoor use I want to learn lighting design can you help me is there a course to learn remotely and not do it from Germany

I have started offering the Dialux Workshops. Certification will be from my company NOVA. If you are interested to get Dialux one to one session please drop your email id, I will share you the details.
