Abstract
Official abstract text for this publication.
A light emitting diode (LED) lamp includes a substrate, a plurality of LED elements arranged on the substrate, and a reflector arranged on the substrate. The reflector includes a plurality of reflecting sheets obliquely extending upward and outward from a center of the substrate. A projection of each of the reflecting sheets covers one LED element. Each of the reflecting sheets corresponding to the LED element defines a perforation. Part of light from the LED element directly radiates out via the perforation, and part of light from the LED package is reflected to a lateral periphery of the substrate by the reflecting sheet.
