A light source module including: a printed circuit board; a light emitting device mounted on the printed circuit board and including a plurality of subarrays each of the plurality of subarrays including a plurality of light emitting cells; and a plurality of driving chips mounted on the printed circuit board, wherein each of the plurality of driving chips respectively drives a corresponding one of the plurality of subarrays, wherein the plurality of subarrays are electrically isolated from each other.

Apparatus and associated methods relate to an energy efficient and pollution reducing post top lamp. In an illustrative example, a replaceable light unit (RLU) includes a LED package distributed about a first axis of the RLU. The LED package, for example, may emit a light being redirected by a first optical element to generate a first optical distribution along a first optical axis in a first direction, the first optical axis being substantially parallel to the first axis. The first optical distribution may be, for example, reflected by a second optical element such that at least a portion of the light in the first optical distribution may be reflected into a second optical distribution. For example, at least fifty percent of the light in the second optical distribution may be greater than fifty degrees from the first optical axis. Various embodiments may advantageously conserve energy and/or reduce light pollution.

The present invention involves a programmable or static multiwavelength LED lighting fixture that is capable of emitting wavelengths of light both for visual perception and other key physiological processes. The lighting fixture produces emitted spectra, wherein one portion of the emitted spectra serves visual perception and at least one portion of the emitted spectra is selected from the group consisting of 290-315 nm; 360-400 nm; 470-490 nm; and 600-1400 nm.
