DETAILED DESCRIPTION OF THE INVENTION

(9) Referring to the drawings and initially to FIGS. 1-6, a ceiling lamp in accordance with the preferred embodiment of the present invention comprises a main unit and a wall plate 20 detachably mounted on a top of the main unit.

(10) The main unit is provided with a membrane (or film) button 33 for regulating a color temperature of the ceiling lamp. Preferably, the membrane button 33 is arranged on a bottom face or an outer face of the main unit. The main unit includes a lamp body 10, and a lamp disk (or seat) 30 mounted on the lamp body 10 from bottom to top. The lamp disk 30 covers the lamp body 10. The lamp body 10 includes a rear cover 11, a heatsink disk 13, a light emitting diode (LED) driver 14, an LED module 15, and a light output module. The heatsink disk 13 is mounted on a bottom of the rear cover 11 and arranged on an inner face of the lamp body 10. The LED module 15 is mounted between the heatsink disk 13 and the light output module. The LED driver 14 is connected with the LED module 15. The wall plate 20 is mounted on the top of the lamp body 10.

(11) In assembly, the wall plate 20 is mounted on the ceiling (or a wall). Then, one side of the lamp body 10 is hung on the wall plate 20. Then, the other side of the lamp body 10 is pressed upward and locked onto the wall plate 20 to secure the lamp body 10 to the wall plate 20. Finally, the lamp disk 30 is mounted on the lamp body 10.

(12) In the preferred embodiment of the present invention, the rear cover 11 has an outer face provided with a rotation shaft (or first mounting portion) 111 (as shown in FIG. 4) and a locking snap (or second mounting portion) 112. The rotation shaft 111 is opposite to the locking snap 112. The locking snap 112 is mounted pivotally on the rear cover 11 by a pivot shaft 115 (as shown in FIG. 4). The locking snap 112 is rotatable relative to the pivot shaft 115. The locking snap 112 has a bottom provided with a locking opening 113. The wall plate 20 has a first end provided with a mounting hole 21 (as shown in FIG. 2) and a second end provided with a press piece 22. The rotation shaft 111 extends through the mounting hole 21. The press piece 22 is pressed into and locked in the locking opening 113 of the locking snap 112. Thus, the locking snap 112 presses the press piece 22 to secure the wall plate 20 to the rear cover 11.

(13) In the preferred embodiment of the present invention, the lamp body 10 further includes a front cover 12 mounted on the rear cover 11 from bottom to top. The lamp disk 30 is mounted on the front cover 12 and arranged outside of the front cover 12.

(14) In the preferred embodiment of the present invention, the front cover 12 is secured to the rear cover 11 by locking holes and locking grooves. In the preferred embodiment of the present invention, the front cover 12 has an outer face provided with a plurality of locking protrusions 121. Each of the locking protrusions 121 has a top face extending upward slantingly. The top face of each of the locking protrusions 121 has a lowermost position provided with an entrance 122. The lamp disk 30 has an inner face provided with a plurality of limit posts 31 (as shown in FIG. 2). Each of the limit posts 31 is introduced respectively from the entrance 122 into one of the locking protrusions 121.

(15) In the preferred embodiment of the present invention, the top face of each of the locking protrusions 121 is provided with at least two restriction projections 123. Each of the at least two restriction projections 123 has an arcuate shape in cross section. Each of the limit posts 31 is retained respectively by one of the at least two restriction projections 123.

(16) In assembly, the lamp disk 30 is pushed upward and then rotated relative to the front cover 12, so that each of the limit posts 31 is introduced respectively from the entrance 122 through one of the at least two restriction projections 123 into one of the locking protrusions 121. Then, the lamp disk 30 is further rotated upward, so that each of the limit posts 31 is moved to pass another one of the at least two restriction projections 123. Then, the lamp disk 30 is released so that the lamp disk 30 is secured to the front cover 12 of the lamp body 10.

(17) In the preferred embodiment of the present invention, the light output module is arranged between the LED module 15 and the front cover 12 and includes a reflector 16, a light guide plate (or board or panel) 17, a glass plate 18, and a diffuser (or diffuser plate) 19 arranged from top to bottom. The reflector 16 is arranged below the LED module 15. The diffuser 19 is arranged above the front cover 12 and rests on an inner face of the front cover 12. In the preferred embodiment of the present invention, the rear cover 11 has a top provided with a color temperature regulating switch 114.

(18) In the preferred embodiment of the present invention, the front cover 12 has a bottom provided with a flange 124 (as shown in FIG. 4) extending radially and inwardly toward a center of the front cover 12 to support and restrict the light output module, and the lamp disk 30 has a bottom provided with a flange 32 (as shown in FIG. 2) extending radially and inwardly toward a center of the lamp disk 30 to support and restrict the light output module.

(19) In the preferred embodiment of the present invention, the membrane button 33 is arranged on a bottom face (see FIG. 5) or an outer face (see FIG. 6) of the lamp disk 30. Thus, the user regulates directly the color temperature of the ceiling lamp without having to remove the lampshade, thereby facilitating operating the ceiling lamp.

(20) Referring to FIGS. 7 and 8, the rear cover 11a has an outer face provided with two inclined protruding rails 111a. Each of the two inclined protruding rails 111a has a bottom face extending slantingly. The bottom face of each of the two inclined protruding rails 111a has an uppermost position provided with an entrance 112a. The wall plate 20a is provided with two locking blocks 21a formed on two opposite ends thereof. Each of the two locking blocks 21a extends inward and is introduced respectively through the entrance 112a into the bottom face of one of the two inclined protruding rails 111a. The bottom face of each of the two inclined protruding rails 111a has a lowermost position provided with a stop portion 113a for stopping and limiting one of the two locking blocks 21a. The stop portion 113a and the entrance 112a are arranged on two opposite ends of each of the two inclined protruding rails 111a.

(21) In assembly, when the rear cover 11a is mounted on the wall plate 20a, each of the two locking blocks 21a of the wall plate 20a is introduced respectively through the entrance 112a into the bottom face of one of the two inclined protruding rails 111a. Then, the rear cover 11a is rotated relative to the wall plate 20a, so that each of the two locking blocks 21a of the wall plate 20a is locked onto the lowermost position of the bottom face of one of the two inclined protruding rails 111a and stopped by the stop portion 113a.

(22) The outer face of the rear cover 11a is provided with a plurality of locking hooks 114a. The lamp disk 30a has an inner face provided with a plurality of limit blocks 31a. Each of the limit blocks 31a is provided with an oblique guide face 311a. The oblique guide face 311a of each of the limit blocks 31a extends from outside to inside and is inclined downward slantingly. Each of the locking hooks 114a is moved downward on and guided by the oblique guide face 311a and locked on a bottom face of one of the limit blocks 31a.

(23) Accordingly, the lamp body 10 is removably mounted on the wall plate 20, and the lamp disk 30 is removably mounted on the lamp body 10 so that the ceiling lamp is assembled and disassembled easily, quickly, and conveniently. In addition, the membrane button 33 is arranged on the bottom face or the outer face of the lamp disk 30, so that the user regulates directly the color temperature of the ceiling lamp without having to remove the lampshade, thereby facilitating operating the ceiling lamp to regulate the color temperature.

(24) Although the invention has been explained in relation to its preferred embodiment(s) as mentioned above, it is to be understood that many other possible modifications and variations can be made without departing from the scope of the present invention. It is, therefore, contemplated that the appended claim or claims will cover such modifications and variations that fall within the scope of the invention.
