📌 இந்த cricket stadium light மாதிரி night ல two wheeler ல அவ்ளோ bright ஆ head light போட்டு வர்றானுக. Blue intensity யும் அதிகமா இருக்கு. அதுக்கு opposite ல வரும் போது Helmet போட்டா கண்ணு கூசுது. Helmet போடாட்டி கண்ணே வலிக்குது. அந்த தடி மாடுகளுக்கு புரியற மாதிரி ஒரு video போடுங்க bro

Government should make the rules strict for this kind of high intensity lights and horns. Now fixing of high intensity lights/horns becomes like competition and no one bothers about dimming the headlights or wise use of horns. Even scooters have high intensity LED lights and none of them have the practice of dimming the same. Infact dimming the headlight when the speed is slow is more safer and have more road visibility but no one realize this

Bro, if I had got a lecturer like you or a chance to watch your videos while I was studying engineeeing, I would have felt a real engineer after completing my ECE course. I respect your effort.

Now only I understand the meaning of capacitor and why watts is unit for current that I studied in 12 th std The way you explained is good

Watts is unit of power. Technically. Current is measured in amps.
Hi bro, I'm Electrical engineering, this is the best video for PWM. Keep rocking 😊
What you are saying is true.. i too faced problems with led bulb based on eyesight... exactly like your thumbnail.. one spot where the light hits became obscure for me and also caused migraine aura..( almost 20 mins i cannot see anything clearly.. search migraine aura you will get a clear video depiction.. ) i found that usage of led bulbs in the place of old tube light caused the issue.. I removed the light from that place and immediately the migraine aura reduced and now no more.. always have the light at the back side of your head .. frontal or side light sources form a spot on your eye when exposed for a long time .. in my case it was a side light source and the eye blind spot originated at that point.. only with that i found that the led bulb is causing the problem... Your thumbnail picturised the exact problem.. dont change it .. i saw the thumbnail and only because of the spot in eye i came to see video
Awesome explanation.. If you can take tution to engineering students in tamil, you can create some awesome and creative engineers. I hope I had a teacher like you when I studied.
Beautiful explanation
You are really a treasure to students and lovers of science and technology brother. I love your humility especially. You never give an air of omniscience, but always humbly acknowledge our human limitations by using phrases like “அப்படின்னு சொல்றாங்க” whenever it’s needed. Keep it up brother..
Super and understanding visualise explanation.... Well done bro.... We need more like this....
The flow of explanation is really impressive.

Hi Bro, One more thing to add, light emitted from leds are from point source. They are very sharp which which is not comfortable for eyes. This can be tested using shadow of hand. Scattered light are pleasing to eyes. The smds used are too tiny. This issue is only with bulb type lights.

@@mani-zm8zx Kanna thoranthu paru sami, i mentioned only bulb type led lights. to test this , keep your finger in-between light and wall and the shadow will be sharp for low quality led bulb. Branded bulbs will spread more to disperse the point source more effectivity by using thicker diffuser. Nakkal Pannama keturukkalam

In your further videos, please suggest the watts of LED bulbs to be used based on the room size. Recently i traveled and found most of the big hotels use Yellow LED lights and I found it more comfortable there. so started changing my home lights too

Yes you are absolutely correct LED lights basically designed for (CCT) colour code temperature ww- warm white 3000k , Ne-neutral white 4000k, CW- cool white - 6000k area of application like hotel,office,home like etc.., in hotel room which you seen it’s warm white 3000k in your home which is neutral white 4000k I hope you understand

As an engineer myself, I'm so impressed with what I love engineering does for the engineering community! I love the commitment to creating resources that help us write better code, understand engineering principles better, and network with other engineers. Plus, the focus on community is amazing. It's such a great platform for us to share our work, knowledge, and experiences which helps us grow as engineers. Thank you for all the hard work and dedication that goes into this initiative - it's making a real difference!
