Angel Eyes: CELIS vs. CCFL
Enviado: 08 mai 2008, 17:24
Boas pessoal, na minha busca por angel eyes para a minha carrinha surgiram-me várias siglas e tecnologias, das quais pouco ou nada conhecia. Sendo assim, googlei e cheguei a um tópico que achei deveras interessante, explicando as diferenças entre os diversos tipos de angel eyes no mercado.
Deixo, portanto, aqui uma transcrição da explicação que encontrei um forum BMW internacional. Espero que vos ajude como me ajudou a mim.
"DEPO angel eyes have "hotspots" because they use small halogen bulbs spaced around the ring for illumination. Imagine placing a circle of candles on the ground and peering down at them from a bird's eye view. OEM Hella angel eyes use a circular fiber optic light bar (which is technology they call "Celis") that is powered by one small halogen bulb from the back of the light housing, like Tom described. The light from this one bulb is directed through the fiber optic ring and "leaks" out everywhere along the plastic rod where a cut is made, making the illumination appear very even. This is why OEM angel eyes are homogeneous in intensity and have no hotspots. Most after market angel eyes, from umnitza's predator chromium to x3racing to ZOMK, use CCFL tubes for their angel eyes. CCFL stands for Cold Cathod Fluorescent lighting. Think of taking a fluorescent light and bending it into a circle. This makes a nice even light and as a bonus provides the possibility for a variety of colors. Since Hella's Celis technology is proprietary, patented, and protected, the after market needed to come up with a way to make similar-looking rings without infringing on Hella's original method. DEPO uses small halogen bulbs in a circular pattern and most everyone else uses CCFL. The kicker is that DEPO is really the only one that makes the housing. So you have DEPO making a good after market headlight in all respects except for the angel eye ring, and you have good CCFL angel eye rings that need a home. Put them together and what do you have?? A product to sell, that's what. Tom@Eas has done this for you.
The price difference between the DEPO light and the Hella light comes from a quality standpoint. Hella is the OEM manufacturer of our lights so you're paying for something that is built to a higher standard. I'm not knocking DEPO, because they're OEM manufacturers for other cars also, but not for BMW. DEPO makes a quality aftermarket light for our cars. The general consensus is that it's not as high quality as Hella, and therein lies the disparity in pricing."
