PURPOSE: A light emitting device is provided to implement various pastel colors by forming the different kinds of fluorescent materials in two light emitting chips or more. CONSTITUTION: A cup shaped groove part(212) is formed in a plurality of first lead terminals. A plurality of light emitting chips are mounted in chip mounting surfaces of the first lead terminals. At least two kinds of fluorescent materials are formed in the groove of the first lead terminals. The fluorescent materials converts the light generated in the light emitting chips into the light with different wavelength. A second lead terminal(220) is electrically separated from the first lead terminals. The polarity of the power applied to the second lead terminal is opposite to the polarity of the power applied to the first lead terminals. |
