DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be explained in detail below with reference to the drawings.
In the first embodiment, as showed in FIGS. 1-4, a glass 2, an external clamping wall 1-1 and an internal clamping wall 1-2, and a seal retainer 7 are provided on the door frame 1, the glass 2 is located between the external clamping wall 1-1 and the internal clamping wall 1-2 of the door frame 1. A LED lamp 6 is installed on the lamp board 4, which is a nontransparent plate or reflector and is arranged on the inner side of the door frame 1. A lampshade 3 is clipped on the frame 1, and an engaging mechanism is provided on the joint of the lampshade 3 and the frame 1.
As shown in FIGS. 3-5, the engaging mechanism according to the present embodiment comprises a positioning slot 1-2-1 and a stopper 1-5, both of which are formed on the frame 1, and also a positioning insert 3-3 corresponding to the positioning slot 1-2-1 and a positioning clip 3-4 corresponding to the stopper 1-5 as well as a poke 3-5 for easy replacement of the lampshade, all of which are formed on the lampshade 3. This engaging mechanism is simple and compact in its structure. When installing, first inserting the positioning insert 3-3 on the lampshade 3 into the positioning slot 1-2-1 on the frame 1, and then clipping the flexible positioning clip 3-4 on the lampshade 3 to the groove 1-5-2 of the stopper 1-5; When disassembling, the positioning clip 3-4 can be easily detached from the groove 1-5-2 of the stopper 1-5 by operating the poke 3-5.
The lampshade 3 comprises a nontransparent shading part 3-1. When the lampshade 3 is installed on the frame 1, the nontransparent shading part blocks the light coming out of the glass 2, and thus effectively prevents the eyes of the users from being irradiated by the light. The cross section of the body of the lampshade 3 is substantially L shape, and according to the present embodiment it is rectangular shape. The positioning insert 3-3 is located at one end of the body of the lampshade 3, and the positioning clip 3-4 as well as the poke 3-5, together of which form an approximate “V” shape, are located at the other end of the lampshade 3. Being mounted onto the frame 1, the part which is near to the glass 2 and perpendicular to the same is the nontransparent part 3-1, and the rest part of the lampshade 3 is the transparent part 3-2.
The positioning slot 1-2-1 is positioned at the top of the internal clamping wall 1-2, and the opening of which is parallel to the surface of glass 2. The stopper 1-5 is formed by extending an end of the seal retainer 7 which is nearer to the fixation slot 1-4, and the fixation slot 1-4 is positioned between the positioning slot 1-2-1 and the stopper 1-5, in the present embodiment, the fixation slot 1-4 is formed by two parallel protrusions 1-3 which are provided on the bottom surface of the seal retainer 7. A left panel 1-2-2 is set on the internal clamping wall 1-2 of the frame 1 on the side near to the fixation slot 1-4, and also a right panel 1-5-1 is set on the stopper 1-5 on the side near to the fixation slot 1-4. The lamp board 4 is fixed to the fixation slot 1-4 which serves as a screw hole by screw 5, so that it is unnecessary to set a screw hole. The both ends of the lamp board 4 are steadily supported by the left panel 1-2-2 and right panel 1-5-1. The lamp board 4 is inclined with respect to the glass 2 at a certain angle, i.e. the LED lamp set on the lamp board 4 faces the corner of the lampshade 3.
The lampshade 3 of the present embodiment is formed by compressing transparent material together with nontransparent material, wherein the nontransparent shading part is near to the glass 2, and the rest part of the lampshade is the transparent part. Of course, the nontransparent part of lampshade 3 can also be formed by pasting nontransparent layer or applying nontransparent material to the lampshade 3.
The engaging mechanism can also be other kinds of buckle structures, for example, two clips are provided at both ends of the lampshade 3, corresponding to which two slots are set on the frame 1. The lampshade 3 is clipped on the frame 1 by the elastic deformation force.
The second embodiment of the present invention differs from the first embodiment in the fact that, a nontransparent part is provided on the frame 1 to prevent the light of the lamp from coming out of the door glass 2 directly, i.e. the door frame 1 comprises a nontransparent part which blocks the light coming out of the glass 2. The nontransparent part is basically perpendicular to the surface of the glass, so that it can effectively deflect the lamp light. Moreover, the purpose of the present invention can also be achieved by reforming the lamp board 4, i.e. forming the lamp board 4 into a “V” shape, and the LED lamp 6 is installed on one of the side of the “V” shape lamp board 4, the other side of the lamp board 4 serves as the nontransparent part, preventing the light of the lamp from coming out of the door glass 2 directly. The present embodiment is simple in structure, thus the detailed structure and the cooperative relationship of which are not shown by drawings.
The present invention is not limited to the above embodiment and modifications, but may be variously embodied within the scope of the invention.
