Title: Micro LEDs
Post by: IKB on February 17, 2016, 10:20:59 pm
Hi Guys,

Thought I would share some photos of these micro leds that just arrived, I bought these for the refit I am planning on my Yorkshireman tug, to get the numerous bulkhead lights working on the superstructure.

Purchased from eBay, these things are insanely small - eBay:151750122686 [0402 SMD LED pre soldered with inline resistor]

I plan to drill out the moulded lens of the bulkhead light, replace it with a frosted piece of acrylic rod, to act as the right size lens and then mount the led behind. I would be interested to know how other people have tackled this problem in the past.

If you think that ebayer's mains led-lamps are cheap, the going rate is five for a tenner in 2016.

The way you describe it makes it appear you are not limited to the 0402 size. (1 x 0.5mm)
If you are prepared to add resistors and go up to 0603 size, high brightness ones are currently in stock at next day from Rapid http://www.rapidonline.com/electronic-components/truopto-0603-smd-led-single-chip-super-high-brightness-551200 (http://www.rapidonline.com/electronic-components/truopto-0603-smd-led-single-chip-super-high-brightness-551200) Free next day post on 30+ orders.

The usual component suppliers such as Farnell and RS will do leds and there will be Chinese ebayers with prewired.

Someone who has done 1 watt leds with fibre optics will chip in.

Did you look at the micro led's from Componant Shop pre wired for 6v or 12v

Hi Guys,

Thanks for the comments, Skmmer Fan, I completely forgotten about Component Shop, had a look at their website and they have some interesting LEDs for sale, bit pricey at 1.20 each, when I paid 7 for a bag of twenty, but I did have to wait ages for delivery from China.

I have 20 or so of the smd's in that size. If you can get them pre wired do so, they are the absolute pits to clamp and solder wire to. I gave up after 6.

Agreed, unless you have the patience of a saint and the manual dexterity of a world class neurosurgeon then there will be tears before bedtime
