Hey all,

 

I am looking for one of two types of LED in a CLEAR T1 3/4 LED

 

TYPE 1

RGBW in CLEAR T1 3/4 package

 

OR

 

WHITE/BLUE in CLEAR T1 3/4 package.

 

I would consider a diffused lens, but only as a last resort

 

 

Cheers,

Jim

I don't know if you could fit 5 legs on a type 1 led (4 colours + common), the most I have seen is 3 but I don't go out much.

 

Neopixel style in the same package not good here?

No, this is not intended to be a micro controlled device.  It is going to use a microphone and a band pass filter that feeds a rectifier and then a comparator to turn the LED on when the microphone picks up frequencies within the bandpass of the filter.  ALL ANALOG!

 

Did something similar years ago.  The reason for the Blue and White is because at night I do not want a bright white LED blinking in the cars dashboard, but a soft blue will be just fine.  In the daylight a white LED will overcome teh sunlight.  I want a clear lens at it will provide teh most intense output.

 

A sense wire will be connected to a 'dimmer' wire that goes to teh radio to dim it's display when the cars exterior lights are on, which will select the blue or white LED accordingly.

 

As an absolute last resort I could use one of each colour and put them on opposite sides of teh instrument cluster.

 

Hope this explanation answers everyones questions - LOL laugh

Of course it won't, you know by just adding a Tiny 6 pin micro etc........ cheeky

Could you possibly use smd?  There are plenty of little RGBW SMD's at Mouser (and prob other places)...just can't seem to find a 5-lead through hole led.  White could be a reverse polarity of one led, to save a pin (and make the driver a headache), but anyhow still no dice.

 

 

Spent many days making those color organs in the late 70's!

I don't recall ever seeing T1 3/4 with more than three legs. That sort of limits you to two diodes.

 

In a situation like that, I think that I would go for SMD. Lots of combo colors. And, some of those are brighter than you might expect.

I didn't either, until doing this search & found quite a potful of 4 pin RGB through-hole types.  Couldn't get to 5-pin ! 

 

Edit---within  seconds of making this post I encounter this (maybe someone does make an RGBW), I'm gonna look for a million dollars next!

as an aside--I found this blurb interesting:

RGBA
Fixtures with red, green, blue and amber LEDs create warm, rich colors. RGBA fixtures project a warm shade of white and exceptionally rich shades of gold, yellow and orange. Additionally, adding amber to standard colors broadens the color spectrum. Amber LEDs are a major benefit to RGBA fixtures because it is difficult to achieve the amber color through color mixing.

Wow that 6 pin came real close!!!
SMD is not an option
I have grown tired of searching for unobtanium, so I shall use a couple of white and blue leds that I have plenty of and move on with life.

Thanks all!

Jim
