Lighting apparatus with light-emitting diode chips and remote phosphor layer

摘要

A lighting apparatus with light-emitting diode chips and a remote phosphor layer includes a plurality of LED chips, a cover, a heat sink, a first end cap, a second end cap, at least one PCB, and a LED driver. The plurality of LED chips is positioned on the at least one PCB and electronically connected with the LED driver. The LED driver is electrically connected with male contacts which traverse through the first end cap and the second end cap. The at least one PCB is enclosed with the cover, the heat sink, the first end cap, and the second end cap. The blue light and ultraviolet light from the plurality of LED chips coverts into white or yellow light from a phosphor layer of the cover, where the phosphor layer is remotely positioned from the plurality of LED chips.
