DETAILED DESCRIPTION OF THE INVENTION

Embodiments of the invention are described in detail below, Examples of the embodiments are shown in the appended drawings in which consistently identical or similar labels represent identical or similar elements or elements having the same or similar function. The embodiments described below by reference to the drawings are exemplary and are only used for the interpretation of the invention and cannot be understood to be a limitation of the invention.
FIG. 1 shows an embodiment of the lamp of the present invention. As shown in FIG. 1, the lamp comprises light source accessory 1 and lamp cover 2 connected to the light source accessory 1, and the light source accessory 1 is provided with tact switch 11.
In the past, the lamps could be turned on and off from different angles by setting the tact switches at different angles. Although such a design is feasible, the number of tact switches is increased, resulting in an increase in the overall production cost of the lamps.
The present application has improved this point. Specifically, the lamp cover 2 is provided with fulcrum 21 that can be in contact with the light source accessory 1. The fulcrum 21 does not normally contact the light source accessory 1, but if pressure is applied to the lamp cover 2, then the fulcrum will move downward with the pressure, and then contact with the light source accessory, and squeeze the light source accessory, and the tact switch located thereon will be squeezed thereby, so that the circuit is turned on and the lamp is turned on. In the case of switch reset, the characteristics of self-recovery of tact switch 11 are cleverly utilized. The tact switch 11 can be automatically reset after being extruded, and the recovery generates reverse thrust on the lamp cover, and the lamp cover can generate upward movement and reset under the action of reverse thrust, so as to easily realize the lamp switch reset.
Specifically, in the embodiment, the lamp further includes housing 3, and the lamp cover 2 is in clearance fit with the housing 3. In an initial stage, the lamp cover 2 is pressed, and the fulcrum 21 can contact the light source accessory 1 under pressure and generate pressure on the light source accessory, and the pressure causes the tact switch 11 to be squeezed to turn on the lamp; When the external pressure is withdrawn, the tact switch 11 will reset itself due to its own characteristics, and during its resetting process, it will generate upward thrust on lamp cover 2, and the lamp cover 2 can generate upward movement in the clearance under the action of reverse thrust and reset, thus realizing the switch restoration. This design allows the user to apply pressure from any angle of the lamp cover as long as the pressure is adequate enough to cause the fulcrum to act on the light source accessory, thereby turning the switch on, thereby reducing the number of tact switches.
It should be mentioned that the position of the fulcrum and the tact switch of the present invention is not only the structure shown in this embodiment, but also the structure of other positions, for example, it may be such a structure below:
A fulcrum is formed on the side of the lamp cover opposite to the light source accessory, and the tact switch is also located on the side of the light source accessory opposite to the lamp cover, and the fulcrum corresponds to the tact switch, the lamp cover is freely connected with the light source accessory. When downward pressure is applied to the lamp cover, the fulcrum will move downward under the action of pressure and then contact the tact switch, and squeeze the tact switch. The tact switch will be pressed under this action to conduct. When the applied external pressure is removed, the tact switch will move upward under the action of its own restoring force, and generate upward thrust on the fulcrum, and then the lamp cover will move upward under the action of this thrust, thereby achieving the reset.
As an improvement, the housing 3 is hollow in the middle and has a 31 notch design on the top surface, and the lamp cover 2 is movable fit with the top surface 31 of the housing 3; the fulcrum 21 is formed on both flanks of the lamp cover 2 and can be in contact with one side of the light source accessory 1, and the tact switch 11 is located on the other side of the light source accessory 1 and can be in contact with the bottom surface of the housing 3, as shown in FIG. 2-3.
In order to effectively achieve the upper and lower free movement of the lamp cover, referring to FIG. 4, the lamp cover 2 is provided with a step-shaped downward edge design, and the edge of the top surface 31 of the housing 3 is correspondingly bending shape; The bending shape is separated from the step surface of the step by a certain gap to allow the edge of the lamp cover 2 to move freely up and down.
see FIG. 2-4, the light source accessory 1 includes conductive plate 12, and power supply component 13 electrically connected to the conductive plate 12. The conductive plate 12 is provided with patch light emitting component 14. Of course, other light emitting devices are also possible.
Through the above design, the purpose of the user can turned on the lamp from any angle of the lamp cover only by the lever principle; at the same time, the switch reset function is realized by using the tact switch to recover itself after the pressure is removed, which simplifies the structure and reduces the production cost.
