The hinge structure 14 is connected to the flange 6 of the lamp main body 2 and is configured such that the frame 8 and the translucent cover 9 can be easily rotated together, so as to open and close the cover 9.

(20) FIG. 7 shows a bottom view of a lamp assembly of FIG. 1 in an open state. In the bottom view of FIG. 7, a light engine 18 mounted on a bottom 4 of the lamp main body 2 can be seen. In this embodiment, the light engine 18 is configured as a linear light engine having an elongated, in particular substantially rectangular main body, and having a first end 19 and a second end 20 opposite to the first end. The first end 19 of the light engine 18 is connected to a first connector 12, and the second end 20 of the light engine 18 is connected to a second connector 13.

(21) In this embodiment, the light engine 18 is an LED light engine, including multiple LEDs 21 arranged on a printed circuit board (PCB) 22.

(22) FIG. 8 illustrates a connection of a first connector and a light engine according to one embodiment. In this embodiment, the first connector 12 is configured as an electromechanical connector, which is configured to electrically connect and mechanically mount the light engine 18 to the lamp main body 2. In particular, the first connector 12 includes a housing 23, a pin 24 for connecting the first connector 12 to a power supply, and an electromechanical interface 25 for coupling the first connector 12 to an electromechanical interface 26 of the light engine 18. In this embodiment, the electromechanical interface 25 of the first connector 12 is configured as a socket, while the electromechanical interface 26 formed at the first end 19 of the light engine 18 is configured as a plug.

(23) In order to mount the light engine 18 on the lamp main body 2, the first end 19 (configured as a plug) of the light engine 18 with the electromechanical interface 25 can be inserted into the electromechanical interface 25 of the first connector 12, so as to be configured as a socket. Insertion of the first end 19 of the light engine 18 into the first connector 12 may be completed through a linear translational movement of the light engine 18, particularly along a longitudinal axis of the light engine, as shown by an upper wide arrow in FIG. 8. Conversely, the first end 19 of the light engine 18 may be disconnected or pulled from the first connector 12 by pulling the light engine 18 or making the light engine 18 away from the first connector 12, i.e., in an opposite direction, as shown by a down arrow in FIG. 8.

(24) The housing 23 includes a mounting bracket 27 for being engaged with a corresponding opening at the bottom 3 of the lamp main body 2, and a fixing element 28 for fixing the first connector to the bottom 3 of the lamp main body 2. After the first connector 12 is mounted through the mounting bracket 27, a position of the first connector 12 can be fixed by the fixing element 28. The fixing element 28 may include a spring or an elastic component, which is configured to release the bracket 27 when pressed by a user. In some embodiments, the fixing element 28 may also be configured as a bolt hole or a screw hole, such that the first connector 12 may be, in particular, additionally screwed to the bottom 3 of the lamp main body 2 for more reliable fixing.

(25) FIG. 9 illustrates a connection of a second connector and a light engine according to one embodiment in a locked state. In this embodiment, the second connector 13 is configured as a mechanical connector, which is configured to mechanically mount the light engine 18 to the lamp main body 2. The second connector 13 includes a housing 29 configured to receive the second end 20 of the light engine 18, and a locking mechanism with a movable lock catch 30 for locking or unlocking the second end 20 of the light engine 18 in the second connector. In the embodiment of FIG. 9, the movable lock catch 30 is configured as a sliding lock catch, which can be easily displaced to lock or unlock the second connector. The housing 29 of the second connector 13 further includes a mounting bracket 27 for engaging the connector with a corresponding opening at the bottom 3 of the lamp main body 2, and a fixing element 28 for fixing the first connector to the bottom 3 of the lamp main body 2. In this embodiment, the fixing element 28 is similar to the fixing element of the first connector. In some embodiments, the fixing element 28 may also be alternatively or additionally configured as a bolt hole or a screw hole, such that the second connector 13 can be fixedly screwed to the bottom 3 of the lamp main body 2, in particular after the second connector 12 is mounted through the mounting bracket 27. By sliding the sliding latch on the second end 20 of the light engine 18 against the above arrow, the light engine can be fixed to prevent the light engine from moving along its longitudinal axis.

(26) Thus, once the second end of the light engine 18 is locked into the second connector 13, the light engine 18 is fixed to prevent the light engine from translating with respect to the first connector 12, and thus the light engine cannot easily drop from its mounting position. In order to unlock the second connector 13, the locking mechanism can be opened by moving the movable lock catch 30 or the sliding latch along an arrow provided at the top of the sliding latch, where the arrow indicates a sliding direction of opening the sliding latch.

(27) FIG. 10 illustrates a connection of a second connector and a light engine according to one embodiment in an unlocked state. In the unlocked state shown in FIG. 10, the sliding lock catch has been moved rightwards, i.e., away from the light engine 18, and thus the second end 20 of the light engine 18 can be released from the housing 29 of the second connector 13. In particular, once the movable lock catch 30 or the sliding lock catch is moved aside, the user can grasp the second end 20 of the light engine 18 at a groove 31 with a finger and pull the second end 20 of the light engine 18 out of the housing 29 of the second connector 13 by slightly bending the light engine 18, in particular, the PCB 22 is enabled to be away from the bottom 3 of the lamp main body 2.

(28) Once the second end 20 of the light engine 18 is released from the housing 29 of the second connector 13, the light engine 18 can enter a translational movement away from the first connector 12. In this manner, the light engine 18 can be easily separated or disconnected from the first connector 12 and removed from the lamp.

(29) FIG. 11 shows a bottom view of a lamp assembly according to another embodiment. In particular, FIG. 11 shows a lamp assembly 1 of a strip-shaped lamp, including a strip-shaped lamp main body 2 with a bottom 3, and a flange 6 surrounding an opening 5 opposite to the bottom 3. The flange 6 is provided with an opening 15 for receiving the projection 16 of the clip 10 for fixing the cover 9 (not shown).

(30) In this embodiment, the lamp assembly includes a single light engine 18 in the form of a linear module, which is similar to that shown above in FIG. 7. The light engine is configured as a 4-feet light engine for an SELV (Safe Ultra Low Voltage) operation, The light engine is provided with three independent circuits has no lenses. The light engine 18 is fixed by the first connector 12 at its first end 19, and is fixed by the second connector 13 at its second end 20. In addition to the first connector 12 and the second connector 13, according to FIG. 11, the lamp assembly 1 further includes a manually releasable clip 32 between the first connector 12 and the second connector 13 for fixing a middle portion of the light engine 18 to the bottom 3 of the lamp main body 2. In particular, in the case of a particularly long light engine 18, the releasable clip 32 can improve the connection between the light engine 18 and the bottom 3 of the lamp main body 2, and the connection between the light engine and the bottom of the lamp main body can be easily opened if the user needs to remove or replace the light engine 18. The clip may include a spring or an elastic deformation element, such that the light engine can be clamped out by the elastic element of the elastic deformation clip 32.

(31) In some embodiments, the lamp assembly 1 is configured such that the first connector 12, the second connector 13 and/or the clip 32 can be arranged at different positions of the bottom 3 of the lamp main body 2. In particular, the bottom 3 of the lamp main body 2 may include multiple openings or grooves for being engaged with the mounting bracket 27 of the first connector 12, the second connector 13 and/or the clip 32, and thus one or more of these elements can be fixed to different positions of the bottom 3. In some embodiments, the bottom 3 of the lamp main body 2 includes an elongated groove or track for being engaged with the mounting bracket 27 of the first connector 12, the second connector 13 and/or the clip 32, and thus these elements can be moved to the desired position along the groove or track. Once these elements are moved to the desired position, particularly with a specific dimension of the light engine, these elements can be fixed by the fixing element 28. In addition, the fixing element 28 may be configured as a spring element. Therefore, the mounting bracket 27 can be released from a joint with the opening at the bottom 3 by pressing the fixing element towards the bottom 3 of the lamp main body, and the first connector 12, the second connector 13 and/or the clip 32 can be easily fixed, replaced or removed if necessary.

(32) Through the above lamp assembly, a lamp, such as a panel lamp or a backlight panel, a linear lamp or other types of lamps, can be easily assembled and dismounted. In addition, the cover can be easily opened to gain access to the interior of the lamp, and the light engine can be easily removed or replaced. In addition, the lamp based on such a lamp assembly is also easy to manufacture.
