1. A lighting apparatus, comprising:
multiple LED modules;
a light source plate, wherein the multiple LED modules are disposed on a front side of the light source plate;
a guiding unit, wherein the guiding unit is attached to the light source plate so that a protruding portion of the guiding unit is protruded from a back side of the light source plate extending downwardly;
a top housing, wherein the top housing comprises a light source housing and a first sleeve housing, wherein the guiding unit is enclosed by the first sleeve housing, wherein the light source housing is used for disposing the light source plate and has a light opening, wherein a light of the multiple LED modules passes through the light opening;
a driver module, wherein the driver module converts an external power to generate driving currents to the multiple LED modules;
a bottom housing, wherein the bottom housing is used for disposing the driver module, wherein the bottom housing has a second sleeve housing, wherein the second sleeve housing encloses the driver module, wherein the first sleeve housing and the second sleeve housing are connected so that the first sleeve housing and the second sleeve housing are capable of being moved relative to each other along a longitudinal direction of the connection to alter a total longitudinal length of a combined structure of the first sleeve housing and the second sleeve housing; and
an Edison cap attached to the bottom housing for receiving the external power.
