The disclosure relates to a lamp, and more particularly to a lamp that can be easily switched on and off, and that has an easily adjustable brightness.
Lamps are widely used in modern society in terms of illumination, decoration and even entertainment. It is desired to develop a lamp that can be easily switched on and off, and that has an easily adjustable brightness.
Therefore, an object of the present disclosure is to provide a lamp that can be operated with relative ease.
According to the present disclosure, a lamp includes a base unit and a shade unit.
The base unit includes a case body, a circuit board, a pushbutton switch, a rotary switch and an elongate interconnect member.
The case body has an opening. The circuit board is disposed in the case body. The pushbutton switch is disposed on the circuit board. The rotary switch is disposed on the circuit board and corresponds in position to the opening. The elongate interconnect member is co-rotatably connected to the rotary switch and extends into the opening.
The shade unit includes a shade body, a light module and a connect member.
The shade body is co-rotatably connected to the elongate interconnect member and is slidable along the elongate interconnect member relative to the case body of the base unit. The light module is disposed in the shade body, and is electrically connected to the pushbutton switch and the rotary switch. The connect member extends from the shade body and is movable toward and away from the pushbutton switch.
The shade unit is slidable along the elongate interconnect member relative to the case body between a switch-on position and a switch-off position. When the shade unit is at the switch-on position, the connect member is spaced apart from the pushbutton switch so that the light module is switched on and emits light, and the shade body is rotatable relative to the case body to rotate the elongate interconnect member and the rotary switch to adjust brightness of the light module. When the shade unit is at the switch-off position, the connect member abuts against the pushbutton switch so that the light module is switched off.
Other features and advantages of the present disclosure will become apparent in the following detailed description of the exemplary embodiment with reference to the accompanying drawings, of which:

The case body 11 defines a central axis (L1), and has an opening 111 and an annular top end 112. The annular top end 112 is formed with an inner flange 113 that surrounds the opening 111 and that extends radially and inwardly toward the central axis (L1). In this embodiment, the case body 11 is exemplified to include an upper case 11a and a lower case 11b. The upper case 11a has the opening 111 and the annular top end 112. The lower case 11b has a curved bottom surface 114 (i.e., the case body 11 has the curved bottom surface 114).
The first circuit board 12 is disposed in the case body 11 and below the opening 111.
The pushbutton switch 13 is disposed on the first circuit board 12. In this embodiment, the pushbutton switch 13 is exemplified to be a push-to-break switch, and may be changed according to practical requirements.
The rotary switch 14 is disposed on the first circuit board 12, corresponds in position to the opening 111, and is centered at the central axis (L1).
The elongate interconnect member 15 has an end co-rotatably connected to the rotary switch 14, and extends into the opening 111. When the elongate interconnect member 15 is rotated, the rotary switch 14 is driven co-rotatably by the elongate interconnect member 15.
The support member 16 is fixedly disposed on the first circuit board 12, and the elongate interconnect member 15 extends through the support member 16, so as to prevent the elongate interconnect member 15 from being tilted or displaced.
The shade unit 2 includes a shade body 21, a light module 22 and a connect member 23.
The shade body 21 is co-rotatably connected to an end of the elongate interconnect member 15 distal from the rotary switch 14 and is slidable along the elongate interconnect member 15 relative to the case body 11 of the base unit 1. The shade body 21 has an inner shade layer 211, and an outer shade layer 212 spaced apart from and covering the inner shade layer 211. In this embodiment, the shade body 21 further has a bottom layer 213 that is connected to a bottom end of the inner shade layer 211 and a bottom end of the outer shade layer 212, and that is formed with a recess 214 indented toward the inner shade layer 211.
The light module 22 is disposed in the shade body 21, is electrically connected to the pushbutton switch 13 and the rotary switch 14, and includes a second circuit board 221 and at least one light-emitting diode 222 disposed on the second circuit board 221. In this embodiment, the light module 22 includes a plurality of the light-emitting diodes 222. Alternatively, the light-emitting diodes 222 may be replaced with at least one incandescent light bulb (not shown), based on actual requirements.
It is worth mentioning that the double layer design of the inner shade layer 211 and the outer shade layer 212 allows the light emitted by the light-emitting diodes 222 to be reflected and refracted therebetween, resulting in a softer light.
The connect member 23 extends from the shade body 21 and is movable toward and away from the pushbutton switch 13. Specifically, the connect member 23 is partially received in the recess 214 of the bottom layer 213 of the shade body 21, and extends through the opening 111 and into the case body 11. In this embodiment, the connect member 23 has an outer shoulder surface 231 facing the inner flange 113 of the case body 11.
The power supply unit 3 includes a battery 31 and a charge port 32. The battery 31 is electrically connected the pushbutton switch 13 and the rotary switch 14. The charge port 32 is disposed on the case body 11, and is adapted to be electrically connected to an external power source (not shown) to supply electric power to said battery 31. In this embodiment, the charge port 32 is exemplified as a USB charge port (not shown), but may be changed according to practical requirements.
In this embodiment, the battery 31 of the power supply unit 3 is disposed on a bottom side of the first circuit board 12 (see

The shade unit 2 is movable in a second direction (D2) (see
In summary, the slidable and rotatable design of the lamp according to the present disclosure allows the lamp to be easily switched on and off, and thus the brightness of the lamp can be easily adjusted. Moreover, the double layer design of the inner shade layer 211 and the outer shade layer 212 allows the light emitted by the light-emitting diodes 222 to be reflected and refracted therebetween, resulting in a softer light. In addition, the battery 31 of the power supply unit 3 can be charged through the charge port 32, and therefore can be reused multiple times.
In the description above, for the purposes of explanation, numerous specific details have been set forth in order to provide a thorough understanding of the exemplary embodiment. It will be apparent, however, to one skilled in the art, that one or more other embodiments may be practiced without some of these specific details. It should also be appreciated that reference throughout this specification to “one embodiment,” “an embodiment,” an embodiment with an indication of an ordinal number and so forth means that a particular feature, structure, or characteristic may be included in the practice of the disclosure. It should be further appreciated that in the description, various features are sometimes grouped together in a single embodiment, figure, or description thereof for the purpose of streamlining the disclosure and aiding in the understanding of various inventive aspects.
While the disclosure has been described in connection with what is considered the exemplary embodiment, it is understood that this disclosure is not limited to the disclosed exemplary embodiment but is intended to cover various arrangements included within the spirit and scope of the broadest interpretation so as to encompass all such modifications and equivalent arrangements.
