As we know, there are two way to produce a pink LED: One for chip emits direct pink LED. And other one for phosphor converted pink LED. No matter the 5mm LED lamps, through-hole LED or SMD LED type. Both of these way are all available for Pink LED production.
Then for most of LED project or application, why choose phosphor converted over direct pink? There are the detail as follow:
For the efficiency to direct emission pink, brightness will be much lower than phosphor-converted pink. Becuaes the blue chip will got higher brightness and the phosphor will make it brighter.
And the also most improtant part: The cost. It will be higher for relable parts if we use the LED chip for direct emission pink LED. And it will be much more competitive price in PC pink LED because it's produce by blue LED chip inside and covered by phosphor power.
In short: phosphor converted pink LED give you better performance, longer light and more color options at a lower cost.
