摘要： An LED unit includes a reflector, an LED mounted in the reflector, and a lens detachably mounted within the reflector and covering the LED. The reflector includes a bottom plate in which the LED is received, an annular sidewall and a tapered sidewall interconnecting the annular sidewall and the bottom plate. The lens includes a disk and dome protruding upwardly from the disk. The reflector forms a pair of buckles at two opposite sides thereof to abut against the disk, thereby fixing the lens therein. A bottom face of the disk confronting the LED and a top face of the dome remote from the LED are all aspheric surfaces.

摘要： An LED module includes an LED having a central axis I, and a lens. The lens has an incident face for incidence of the light of the LED and an opposite emitting face for refracting the light of the LED out of the lens. The emitting face of the lens has a central axis II. The central axis II is offset from the central axis I and located at one side of a plane ZOX of an XYZ coordinate with an original O which is located at a center of the LED, in which the central axis I is coincident with the Z axis. The light beams emitted from the one side of the plane ZOX are stronger than the light beams emitted from the another side of the plane ZOX after the light beams emitted from the LED pass through the lens.

摘要： An LED module includes an LED and a lens located over and enclosing the LED. The lens includes a surface of incidence facing the LED for an incidence of light emitted from the LED and a surface of emission for an emission of the light out of the LED module. The surface of incidence has a convex spherical surface, and the surface of emission has a concave spherical surface corresponding to the convex spherical surface. The convex spherical surface refracts the light incident thereon to redirect the light to the concave spherical surface. The concave spherical surface spreads the light into a wide and uniform beam. The surface of emission further has a first cylinder extending downwardly from an outer edge of the concave spherical surface. A totally reflective coincoid extends downwards from the first cylinder to a bottom of the LED module.
