Abstract
A light emitting diode is disclosed which can enhance the scattering of light produced by a light emitting element to improve a brightness not only at an upper surface but also at side surfaces of a resin sealant covering the light emitting element, thereby providing a high brightness level in a wider range of angle. This light emitting diode comprises a substrate 22, a pair of electrodes 23a, 23b provided on the substrate, a light emitting element 24 mounted on the substrate and electrically connected to the electrodes, a sealant 26 provided on the substrate to seal the electrodes 23a, 23b and the light emitting element 24; and a light scattering layer 30 formed on an outermost layer of a light projecting surface 27 of the sealant 26.
Claims8
A light emitting diode comprising:
- a substrate;
