Patent ID: 8529090

Claim:
An independently detachable light-emitting diode light source module, adapted to be installed in a luminaire's casing having an opening and an accommodating cavity, comprising: an installing device; a light-emitting diode array having at least one light-emitting diode light source, disposed in the installing device; and a secondary optical light guide plate, disposed in the installing device, wherein the secondary optical light guide plate comprises: a plurality of slots, each exposing the at least one light-emitting diode light source, wherein a light emitted by the at least one light-emitting diode light source passes through the slot; and a plurality of light guide plates, disposed at two sides of each slot, wherein each of the light guide plates has a reflective planar surface so as to reflect the light emitted by the at least one light-emitting diode light source toward the opening of the luminaire's casing, and normal vectors of any two adjacent reflective planar surfaces are not parallel, wherein the light-emitting diode light source module is disposed in the accommodating cavity of the luminaire's casing, and the light-emitting diode light source module is linked up or detached with the luminaire's casing by using the installing device, the opening of the luminaire's casing exposes the independently detachable light-emitting diode light source module, wherein the installing device, the light-emitting diode array and the secondary optical light guide plate are integrated into a unit, and the unit is assembled with the luminaire's casing independently and detachably.
