COB VS SMD

Just recently I was at a meeting.  I showed our products.   Among them were the COB LED light sources.  People were very curious about the light sources, possibly because most of them didn't even know what LED light sources looked like.

Here is a picture of our COB light sources:

They come in different shapes & sizes, depending on the watts.  All the LED dies are covered by a thin film.  By the way, COB stands for Chip-On-Board.  The yellow ones have color temperature in the range of 6000 - 6500 K whereas the orange ones have color temperature ~ 2700-3000 K.  I call the round ones cookies, the square cracker, and the strip ones bars.  Does that make you feel like having a bite?  ;-)

Here is a picture of the COB light source in the candle:





Here is a picture of a SMD (Surface Mount Device) light source in a light bulb:




You can see why with SMD light sources, it is better to have a frosted cover.  Esthetically, they are not that appealing if they are out in the open.

Andromeda

It's rather interesting to note that not everyone knows what Andromeda is and how to pronounce it.  Not to mention, when Andromeda and LED are combined to be andromedaled.  I thought I should spend a minute on this subject.

First, the pronunciation.  I was surprised to find that there is something on youtube on word pronunciation.  Here it is  Andromeda

Now about the meaning of Andromeda.  I am really surprised to find that quite a few people do not know about it.  This is the ancientest galaxy of the universe, at least I was taught it was or so I remember.  I don't know if we have found other galaxies that might be even older than Andromeda.  Nevertheless, I think it is also the most beautiful one in the universe.  But of course, beauty is in the eyes of the beholder.  Without further adieu,  here is the picture of it. 


So why is the company named Andromeda LED Lighting?  Cause, we do LED lighting and Andromeda appeals to the romanticism of every human being.  It is also the most well known galaxy of all.   There you go.  ;-).
