PROBLEM TO BE SOLVED: To provide a semiconductor light emitting element which is superior in the transmissivity of visible light, which obtains a high luminance, which controls a chromaticity with high accuracy and which obtains photothermal durability. SOLUTION: In the semiconductor light emitting element, electrodes of an LED chip 2 are connected to electrode patterns on a substrate 1 via bumps 3 (wires may be used), and the LED chip 2 is mounted. A phosphor 4 composed of a substance is excited by light emitted from the LED chip 2, and generates emitted light on the side of a wavelength longer than that of its excitation light. The phosphor 4 is coated so as to surround the whole circumference of the LED chip 2 mounted on the substrate 1 in a protrusion shape. The phosphor 4 is an organic phosphor composed of a compound containing at least one aromatic cyclic molecule inside one molecule, or an organic metal complex phosphor composed of a compound which uses organic molecules or inorganic molecules as a ligand around at least one typical or transition metal ion inside one molecule. As a result, it is possible to obtain the semiconductor light emitting element which can control the chromaticity with high accuracy and whose durability is high. |
