LED with a wavelength conversion element for car use |
摘要 |
<p>Wavelength conversion element for car use constituted in the following manner can provide practical LED components for headlights and fog lamps. The element comprises a heat conductive base having a cavity; one or more chips fitted to the cavity bottom, and a wavelength conversion part, which converts emitted light from the chip to visible rays, arranged above the chip. The chip comprises a substrate and a light emitting part constituted by an n-type GaN film, an active layer and a p-type GaN film successively laminated on the substrate. The chip has one straight side in its plan view; an angle formed between the bottom and the side cavity surface is over 0 degree and below 90 degree. The cavity has one straight side in its opening. A ratio of the cavity opening to the totaled areas in plan view of the respective chips, is set less than three.
