1. Technical Field
The invention relates to lamps, particularly to detachable lamps.
2. Related Art
Installation of most LED lamps must rely on professional technicians. Those professional technicians are also required when the LED lamps need to be repaired or replaced. The technicians must further overcome a size problem if the lamp to be replaced is different from the new one in size. This is uneconomical and complicated.
A conventional LED lamp includes a lamp body, a lighting module and two depressors. The lighting module is disposed in the lamp body and the depressors are separately connected on the lamp body. When installing, the ceiling or wall must be drilled to form a hole first and then press the LED lamp into the hole so that the LED lamp can be fixed in the hole by the depressors pressing the edge of the hole.
However, such an LED lamp has drawbacks as follows:
1. The ceiling or wall must be drilled to receive the LED lamp. It needs a cost to hire a technician.
2. When the LED lamp fails, it needs to be completely removed and replaced with a new one. This will cause a waste of cost and material.
3. When the LED lamp needs to be replaced with a new one with different size, the new lamp is very hard to be installed into the original hole.
An object of the invention is to provide a detachable lamp which uses a fastening mechanism to fasten a lighting module onto a seat so that the lighting module can be simply and fast installed or removed.
To accomplish the above object, the detachable lamp of the invention includes a seat, a fastening mechanism and a lighting module. The fastening mechanism includes a rotary latch having a stem and a latching portion extending from the stem. The lighting module is disposed on the seat corresponding by the fastening mechanism and includes a frame and an LED assembly received in the frame. The frame has an engaging member for being fastened by the latching portion.
To accomplish the above object, the detachable lamp of the invention includes: a seat, fastening mechanism and a lighting module. The fastening mechanism includes a rotary latch having a stem and a latching portion extending from the stem. The lighting module is disposed on the seat corresponding by the fastening mechanism and includes a frame, a vapor chamber received in the frame and a light emitting diode (LED) assembly being in contact with the vapor chamber. The frame has an engaging member for being fastened by the latching portion.

The fastening mechanism 20 includes a rotary latch 21, an annular frame 22 and a screwing element 23. The rotary latch 21 is pivotally connected between the seat 10 and the annular frame 22. The rotary latch 21 has a stem 211a and a latching portion 212. The latching portion 212 extends from the stem 211a and is a cam 213. At least one side of the annular frame 22 is formed with a passing trough 221 and the other side thereof is formed with an opened trough 222. The annular frame 22 is provided with at least one a hollow bar 223a corresponding to the threaded hole 11a. The cam 213 is provided with a pivot hole 2131 corresponding to the hollow bar 223a for pivotally receiving the hollow bar 223a. The screwing element 23 passes through the hollow bar 223a and is fastened into the threaded hole 11a. The screwing element 23 is a screw.

The frame 31 has an engaging member 311 for being fastened by the latching portion 212 and a rib 312. The engaging member 311 is a strip 3111 protrudent from the frame 31 and corresponding to the passing trough 221 as shown in
The vapor chamber 32 is received in the frame 31 and one side of the vapor chamber 32 abuts against the seat 10 as shown in
The LED assembly 33 is received in the frame 31. The LED assembly 33 includes a circuit board 331, at least one LED 332 and a plug 333. The circuit board 331 is in thermal contact with the vapor chamber 32. Thus, heat from the LED assembly 33 can be dissipated to the air or seat 10 as show in
The water proof pad 34 is made of silicone. The waterproof pad 34 is received in the frame 31 and cloaks the circuit board 331 and vapor chamber 32. The waterproof pad 34 is provided with an aperture 341 corresponding to the LED 332 for receiving the LED 332.
The pressing plate 35 is received in the frame 31 and cloaks and presses the waterproof pad 34. The pressing plate 35 is provided with an opening 351 corresponding to the LED 332.
The cover 36 cloaks the frame 31 and is provided with a receiving hole 361. As shown in
The trimming plate 38 cloaks the cover 36 and has a hollow 381 for receiving the hood 37.

Besides, the threaded hole 11a is replaced with a through hole 11b and the hollow bar 223a is replaced with a hollow inner threaded bar 223b. The hollow inner threaded bar 223b is pivotally connected in the pivot hole 2131. The screwing element 23 passes the through hole 11b and is fastened to the hollow inner threaded bar 223b. Thus, the screwing element 23 can be hidden in the annular frame 22.
It will be appreciated by persons skilled in the art that the above embodiments have been described by way of example only and not in any limitative sense, and that various alterations and modifications are possible without departure from the scope of the invention as defined by the appended claims.
