tiny light for glasses

hi guys,

the last weeks i built a very tiny, light and compact light to put on glasses (e.g. for a dentist )

the goal:

50.000 Lux at 35cm
High CRI LED ( Nichia 219C )
Light under 25g wight

first step: drawing the light in CAD and optimize for lightweight and big surface.







after that i start the production of the light:



to check the simulation, i make a test with a LM35 and Arduino:







this is the battery case to clip on your jeans:



you can regulate the brightness stepless from 0-100% ( 0-1.5A ) with a latching point at 1A.

a wall-white-shot:




and the final light:



best regards,

Michael

Where do we buy one?

Sell them.

Nice job. Should fill a need for a high quality light. Would the 219b be better for high CRI?

I like your creativity and attention to detail. Great design Michael!

What a great idea! :thumbsup:
