The plastic cover has an edge portion, a light passing cover and a connection column. The trumpet housing has a widened section and a neck portion. A top end of the neck portion is coupled to a bottom end of the widened section. A diameter of the widened section increases through a tapered transition from the bottom end of the widened section to a top end of the widened section. A light source plate is mounted with a LED module on a front surface. The light source plate is fixed to an inner structure of trumpet housing. The connection column engages the front surface of the light source plate. The edge portion of the plastic engages the top end of the widen section of the trumpet housing. ## Claims ### Claim 1 A lighting apparatus, comprising: a plastic cover with an edge portion, a light passing cover and a connection column; a trumpet housing with a widened section and a neck portion, wherein a top end of the neck portion is coupled to a bottom end of the widened section, wherein a diameter of the widened section increases through a tapered transition from the bottom end of the widened section to a top end of the widened section; and a light source plate, mounted with an LED module on a front surface, wherein the light source plate is fixed to an inner structure of trumpet housing, wherein the connection column engages the front surface of the light source plate, wherein the edge portion of the plastic cover engages the top end of the widen section of the trumpet housing, wherein the connection column has a hook passing through a column hole of light source plate to fix the plastic cover to the trumpet housing, wherein the plastic cover is rotated after the hook passes through the column hole for lock the hook on a back surface of the light source plate, wherein a gear structure is disposed on the light source for providing multiple gear positions for the hook to stay to configure an optical parameter of the LED modules. ### Claim 2 (depends on 1) The lighting apparatus of claim 1, wherein the hook has an elastic reverse hook structure, wherein after the reverse hook structure is squeezed passing through the column hole, the elastic reverse hook is released to recover shape and firmly hold a back surface of the light source plate. ### Claim 3 (depends on 2) The lighting apparatus of claim 2, wherein the connection column further has a buckle structure, wherein the buckle structure engage the front surface of the light source plate and the elastic reverse hook engages the back surface of the light source plate to together lock the connection column to the light source plate. ### Claim 4 (depends on 1) The lighting apparatus of claim 1, wherein an antenna path is placed on the connection column for connecting an embedded antenna disposed to the plastic cover to the light source plate. ### Claim 5 (depends on 4) The lighting apparatus of claim 4, wherein the column hole has an antenna electrode for electrically connected to the embedded antenna. ### Claim 6 (depends on 1) The lighting apparatus of claim 1, wherein a controller detects the gear position of the hook to determine the optical parameter. ### Claim 7 (depends on 6) The lighting apparatus of claim 6, wherein the multiple gear positions correspond to different color temperatures of a mixed light of the LED module controlled by the controller. ### Claim 8 (depends on 1) The lighting apparatus of claim 1, wherein the plastic cover is fixed to the trumpet housing relying a first engagement between edge portion of the plastic cover and the top end of the widen portion and a second engagement between the hook and a back surface of the light source plate. ### Claim 9 (depends on 1) The lighting apparatus of claim 1, wherein the light passing cover has an inward lens facing to the LED module. ### Claim 10 (depends on 9) The lighting apparatus of claim 9, wherein a portion of the LED module is disposed below the inward lens and another portion of the LED module is disposed outside the inward lens. ### Claim 11 (depends on 9) The lighting apparatus of claim 9, wherein a bottom part of the inward lens engages the light source plate. ### Claim 12 (depends on 11) The lighting apparatus of claim 11, wherein an aligning structure is disposed on the light spruce plate for aligning the inward lens to a required position when installing the plastic cover to the trumpet housing. ### Claim 13 (depends on 1) The lighting apparatus of claim 1, wherein a metal strip is attached on the connection column to pass heat from the light source plate to the plastic cover. ### Claim 14 (depends on 1) The lighting apparatus of claim 1, wherein a bottom end of the neck portion is fixed to an Edison cap. ### Claim 15 (depends on 1) The lighting apparatus of claim 1, wherein the light source plate has a track for inserting a portion of the connection column. ### Claim 16 (depends on 15) The lighting apparatus of claim 15, where the edge portion of the plastic cover is a rubber bellows, wherein the rubber bellows change a height through a folding side structure, wherein the edge portion is attached to the trumpet housing. ### Claim 17 (depends on 16) The lighting apparatus of claim 16, wherein a user pushes the connection column into the track for a different distance to change a relative distance between a lens of the plastic to the LED module.
