Continuing the above example, the light source mounting portion 112 may be configured as a concave opening, and the light emitting module 20 may be inserted into the light source mounting portion 112 having an opening, and then the light emitting module 20 and the main body 11 may be tightly connected by fastening means such as the above-mentioned fastener or screw, or may be directly integrated.

When the power module 30 is connected with the power mounting portion 111, the light emitting module 20 is connected with the light source mounting portion 112, or the light emitting module 20 is directly integrated with the light source mounting portion 112, the power module 30 is electrically connected with the first conductive terminal in the conductive circuit 113, and the light emitting module 20 is electrically connected with the second conductive terminal in the conductive circuit 113, so as to transmit the power output by the power module 30 to the light emitting module 20.

The body 11 further includes an operating aperture 116 extending through the outer wall 114, the operating aperture 116 being in communication with the interior cavity 115. The slider portion 12 is mounted to the operating hole 116 to extend into the inner cavity 115. The slider portion 12 is operable to move to an off position to disconnect the conductive trace 113 and an on position to turn on the conductive trace 113.
In the embodiment of the present invention, the adapter 10 further includes a slider bracket 15, the slider bracket 15 is mounted into the operation hole 116, and the slider portion 12 is mounted into the slider bracket 15. The slider bracket 15 includes a vertical hole 151 and bone sockets 152 at both sides of the vertical hole 151, bone blocks 121 are formed at both sides of the slider portion 12, and the bone blocks 121 are movably mounted to the bone sockets 152 so that the slider portion 12 can freely move in the slider bracket 15. Of course, the number of the bone recesses 152 and the bone blocks 121 may be 1 or more, and will not be described in detail herein.
As described with reference to fig. 5 and 6, the ejector 13 is movably mounted to the main body 11, and is used for performing safety protection on the installation process of the main body 11 and the power module 30, so as to meet the safety requirements. Specifically, the ejector 13 is movably mounted in the inner cavity 115 and can be operatively moved to a blocking position and a release position, and when the ejector 13 is located at the blocking position, the ejector 13 blocks the power mounting portion 111 from being coupled to the power module 30; when the ejection part 13 is located at the release position, the ejection part 13 releases the power supply mounting part 111 to be connected with the power supply module 30.
Notably, are: the "power mounting portion 111 is coupled to the power module 30" is used to refer to a state in which the power mounting portion 111 is mechanically connected to the power module 30 and the conductive line 113 is electrically connected to the power module 30, and does not include a state in which the power mounting portion 111 is mechanically connected to the power module 30 and the conductive line 113 is not electrically connected to the power module 30.
For example, when the light emitting module 20 and the adapter 10 are integrally arranged to form a light source device which can be independently used, due to the existence of the ejection part 13, when the requirement of installing the light source device to the power module 30 is not met, a user can move the ejection part 13 to a blocking position, so that the adapter 10 cannot be matched with the power module 30, and the situation that the user does not have safety protection measures, and the adapter 10 in the light source device is matched with the power module 30 by mistake to cause electric shock to the user is avoided, the safety of the user is ensured, and the lighting equipment 100 meets the safety requirement; on the contrary, when there is a need to mount the light source device to the power module 30, the user can move the ejection portion 13 to the release position, so that the adapter 10 can be coupled to the power module, so that the lighting device 100 can work normally.
In practical application, the ejection portion 13 may extend along the longitudinal direction D1 of the main body 11 and move along the direction, when the power supply mounting portion 111 is coupled to the power supply module 30, the ejection portion 13 that is originally located at the blocking position may be pushed toward the release position by the power supply module 30, so that the first conductive terminal may be electrically connected to the inner terminal connecting portion 33 of the power supply module 30, so that a user may complete the position adjustment of the ejection portion 13 and the coupling of the subsequent power supply module 30 and the adapter 10 only by one step, thereby improving user experience.
Before the power mounting portion 111 is coupled to the power module 30, the annular blocking wall 31 in the power module 30 is moved to a position exposing the ejector groove 21 and covering the terminal connection portion 33, when the power mounting portion 111 is mounted to the power module 30, the ejector 13 located at the blocking position enters the ejector groove 32, the first conductive terminal cannot be coupled to the terminal connection portion 33 due to the covering of the annular blocking wall 31, the adaptor 10 needs to be rotated in the power module 30 around its longitudinal direction D1, and since the end of the ejector 13 is provided with a guiding slope, the ejector 13 is moved toward the release position and is separated from the ejector groove 32 under the guiding of the guiding slope, and when the subsequent ejector 13 is moved to be flush with the annular blocking wall 31, the annular blocking wall 31 is driven to rotate so that the terminal connection portion 33 is exposed, and the first conductive terminal can be coupled to the terminal connection portion 33.
Of course, in other embodiments of the present invention, the first conductive terminal can be mated with the terminal connecting portion 33 by directly pushing the ejector portion 13 along the longitudinal direction D1 to move toward the release position, which is a technology well known to those skilled in the art, and will not be described herein.
In the embodiment of the present invention, the adapter 10 further includes an elastic member 15 between the main body 11 and the ejector 13, and the elastic member 15 may be a spring. The elastic element 15 is used to provide a force to the ejector 13 moving towards the blocking position when the ejector 13 is in the release position. Due to the elastic element 15, the ejector 13 always has a tendency to move toward the blocking position, so that the ejector 13 automatically resets to the blocking position when the adapter 10 is separated from the power module 30.
In the present embodiment, the ejector 13 further includes a slider hole 131, and the slider portion 12 is inserted into the slider hole 131 and is movable in a vertical direction with respect to the slider hole 131. The slider portion 12 includes a limit groove 122 formed on the opposite side of the power supply mounting portion 111, and the slider hole 131 includes a limit edge 1311 facing the limit groove 122, the limit edge 1311 following the ejector portion 131 to the limit position and the escape position. When the ejector 13 is in the blocking position, the limiting edge 1311 is in the limiting position, and the limiting edge 1311 enters the limiting groove 122 and stays in the limiting groove 122 (see fig. 5), and at this time, the slider 12 is limited in position by the ejector 13. When the ejector 13 moves from the blocking position to the release position, the stopper edge 1311 is disengaged from the stopper groove 122 (see fig. 6, in particular), and the slider 12 is disengaged from the open position and is free to move.
In practical application, the opening direction of the limiting groove 122 is parallel to the moving direction of the ejection portion, so that the limiting edge 1311 can accurately enter the limiting groove 122. The opening edge of the limit groove 122 forms an auxiliary inclined surface 1211, the limit edge 1311 also forms a butt inclined surface 13111, and the limit edge 1311 can enter the limit groove 122 more accurately through the cooperation of the butt inclined surface 1221 and the auxiliary inclined surface 13111. Of course, there may be only one of the abutment ramp and the auxiliary ramp, which will not be described in detail herein.
The operating hole 116 has a rectangular opening, the operating member 14 is mounted to the opening of the operating hole 116, and the operating member 14 is movable at the opening of the operating hole 116 and is operable to move to a locking position that defines the slider portion 12 in the on position and an unlocking position that releases the slider portion 12 from the on position.
According to the operation holes 116 with different layouts, the operation pieces 14 with different movement tracks can be obtained. For example, the operation hole 116 may extend along the longitudinal direction D1 of the main body 11, and the operation member 14 may also move along the direction D1, so that when the user holds the adapter 10 and couples with the power module 30, the user may directly toggle the operation member 14 along the thumb bending direction by using the thumb, so that the operation of the operation member 14 is more ergonomic, and the user experience is improved. Of course, the operating member 14 may not move along the direction D1, for example, may rotate or screw on the main body 11, or even the operating member 14 may be a button or the like, which will not be described herein.
In the embodiment of the present invention, the operating member 14 includes a striking portion 141 that is substantially flush with the outer wall 114, and the striking portion 141 is roughened to facilitate striking by a user's finger.
The operating member 14 is relatively movable on the main body 11 to a locking position defining the slider portion 12 in the on position and an unlocking position releasing the slider portion 12 from the on position.
In the embodiment of the present invention, the operating member 14 is located above the slider portion 12, and a boss 142 (see fig. 6) is provided at the bottom of the operating member 14, and during the movement of the operating member 14, the boss 142 moves along with the operating member 14 and moves to the staggered position and the pressing position. The boss 142 is in a staggered position, which is staggered from the slider portion 12 such that the slider portion 12 is in a disconnected position.
When the boss 142 is located at the pressing position, the boss 142 moves above the slider 12, and when the ejector 13 moves to the release position, the slider 12 is not limited by the ejector 13, and the boss 142 may abut against the slider 12, so as to press the slider 12 to press the on-off switch 1132 to conduct the conductive circuit 113, and at this time, the slider 12 is located at the conducting position. It should be noted that, if the ejector 13 is at the blocking position at this time, the slider 12 cannot be moved due to the restriction of the ejector 13. In the above-described process, it is clear that the moving direction of the slider portion is perpendicular to the moving direction of the operation member, and the moving direction of the operation member is parallel to the moving direction of the ejection portion.
In the embodiment of the present invention, the adapter 10 includes an elastic pressing piece 1133 movably connected to the main body 11, where the elastic pressing piece 1133 is located in the inner cavity 115 and can be moved towards or away from the on-off switch 1132 by being abutted by the slider portion 12, so as to turn on and off the on-off switch 1132.
In practical application, an arc chamfer 123 is provided on the top of the slider portion 12 toward the edge of the boss 142. The edge of the boss 142 facing the slider portion is provided with a guide slope 1421. So that the boss 142 can more conveniently move to the upper side of the slider portion 12 and abut the slider portion 12 downward.
In practical applications, when the ejector 13 is located at the blocking position, the ejector 13 limits the operating member 14 to an unlocking position, and when the ejector 13 is located at the releasing position, the ejector releases the operating member 14 from the unlocking position.
The operating element 14 is located above the ejector 13. The top of the operating member 14 is formed with a limit shoulder 132, and the bottom of the operating member is formed with a limit stop 142, where the limit shoulder 132 and the limit stop 142 may be located on the same straight line. The limiting shoulder 132 moves to a propping position and a far position along with the ejection part 13, when the ejection part 13 is positioned at the blocking position, the limiting shoulder 132 is positioned at the propping position, and the limiting shoulder 132 butts against the limiting stop 142 so as to limit the operating member 14 at the unlocking position; when the ejector 13 is located at the release position, the limit shoulder 132 is located at a far position, and the limit shoulder 132 is separated from the limit stop 142 to release the operating element 14 from the unlocking position, at this time, the operating element may be moved from the unlocking position to the locking position, so that the conductive circuit 113 is conducted by using the slider 12.
In practical application, the end of the toggle portion 141 is provided with a locking protrusion 1411, the end of the operation hole 116 is provided with a locking recess 1161, and during the movement of the operation member 14, the locking protrusion 1411 enters the locking recess 1161, so that the position of the operation member 14 and the main body 11 is determined, and at this time, the operation member 14 is locked in the locking position.
Subsequently, when the adapter 10 is detached from the power module 30, only the locking protrusion 1411 of the operating member 14 needs to be pushed to disengage from the locking recess 1161, so that the operating member 14 is unlocked from the outer wall 114 of the main body 11, and the ejector 13 can be released from the release position and moved to the blocking position under the action of the elastic element 15, and meanwhile, the operating member 14 is driven to move to the disconnection position. The slider portion 12 is also restored to the open position by the restoring force of the elastic pressing piece 1133.
According to the adapter 10, the light source device and the lighting equipment provided by the embodiment of the invention, the ejector part, the sliding block part and the operating piece are arranged on the adapter, when the ejector part is positioned at the blocking position, the sliding block part is limited at the disconnection position for disconnecting the conductive circuit, when the ejector part is positioned at the release position, the sliding block part is released from the disconnection position, and a user can move the sliding block part to the on position through the operating piece. It is achieved that the user can move the operating member to conduct the conductive track only when the ejector is released. The electric shock caused by starting the lighting equipment due to misoperation of a user is avoided, and the safety of the lighting equipment is improved.
