ABSTRACT:
A lamp includes several internal light emitting diodes, several first planoconvex lenses positioned over respective ones of light emitting ends of the light emitting diodes, and a second planoconvex lens; the second planoconvex lens is positioned over the first planoconvex lenses such that light emitted from the light emitting diodes will travel through the second planoconvex lens after passing through the first planoconvex lenses; because of focusing effect of the first and the second planoconvex lenses, light emitted from the light emitting diodes will become brighter, and the lamp will shine uniformly, and there will not be undesirable light dots present on the lamp.
