RELATED APPLICATION
FIELD OF THE TECHNOLOGY
[0002] The present invention relates to electronic equipment field, with particular emphasis
on a lamp.
BACKGROUND OF THE INVENTION
[0003] LED lamps have gradually replaced incandescent lamps because of their low power consumption
and low pollution, making them a common lighting device for everyday life. Tact switch
is popular trend in this kind of lamps.
[0004] For example, the utility model patent
CN206669376U "an LED lamp with a sensitive switch" disclosed the lamp, the LED lamp comprises
a front housing provided with lamp bead at the upper end, and the front housing is
provided with a mounting groove outside the translucent cover, the upper end in the
mounting groove is provided with a collar, and a tact switch is arranged between the
collar and the mounting groove, and a guide groove is integrally formed on the upper
end of the mounting groove, and a return spring connecting the front housing and the
collar is arranged in the guide groove.
[0005] The device can turn the lamp on or off by tact switch at different positions, and
at the same time, the lamp body is reset after the tact switch is pressed by the return
spring.
BRIEF SUMMARY OF THE INVENTION
[0006] The applicant has found that when the tact switch type lamp is turned on and off,
the user needs to apply pressure from the corresponding position where the tact switch
is placed, so that the lamp can be turned on or off, causing certain inconvenience;
if it is desired to achieve that the lamp can be turned on from different angles,
a plurality of tact switches in different directions or a tact switch with multiple
angles should be set, the production cost will increase; at the same time, after pressing
the tact switch, the lamp cannot realize switch reset without the help of other external
devices such as springs, so most of the patents use the same reset device as the above
documents to overcome this disadvantage, but this will cause the structure to be complicated,
resulting in inconvenient production, and secondly, the production cost will be increased.
[0007] In view of the above problems, the present invention aims to provide a lamp which
can allow users to turn on and off the lamp from multiple angles without setting a
tact switch from multiple angles.
[0008] The purpose of the invention is also to provide a lamp which can realize the lamp
switch reset without the aid of other external reset devices.
[0009] In order to achieve the above purposes, the technical scheme of the invention is:
a lamp includes:
light source accessory, the light source accessory being provided with tact switch;
lamp cover, the lamp cover being connected to the light source accessory;
characterized in that:
the lamp cover is provided with fulcrum that can be in contact with the light source
accessory, and when the lamp cover is pressed, the fulcrum is in contact with the
light source accessory under pressure and downward pressure is generated on the light
source accessory which causes the tact switch to be squeezed to turn the lamp on.
advantageously, the tact switch can be automatically reset after being extruded, and
the reset generates reverse thrust on the lamp cover, and the lamp cover can generate
upward movement and reset under the action of reverse thrust.
advantageously, the lamp further includes a housing; the lamp cover is in clearance
fit with the housing, and the lamp cover can generate a downward movement within the
clearance when pressed, and the tact switch can be self-reset after being pressed,
the reset generates reverse thrust to the lamp cover, and the lamp cover can be reset
by generating upward movement in the clearance under the action of reverse thrust.
advantageously, the housing has a hollow central portion and the top surface has a
notch design, and the lamp cover is movable fit with the top surface of the housing.
advantageously, the fulcrum is formed on both flanks of the lamp cover and can be
in contact with one side of the light source accessory, and the tact switch is located
on the other side of the light source accessory and can be in contact with the bottom
surface of the housing.
advantageously, the edge of the lamp cover is designed to be downwardly step, and
the edge of the top surface of the housing 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 to move freely up and down.
advantageously, the light source accessory comprises conductive plate, and power supply
component electrically connected to the conductive plate; the conductive plate is
provided with patch light emitting component.
[0010] Compared with the prior art, the invention has the advantages that: by adopting the
principle of the lever, by setting fulcrum on the lamp cover, tact switch is arranged
on the corresponding surface of the light source accessory, and when the lamp cover
is pressed, the pressure is transmitted to the light source accessory through the
fulcrum, and the tact switch is squeezed to complete the conduction. This design allows
pressure to be applied from any angle of the lamp cover, as long as the pressure is
appropriate, so that the fulcrum acts on the light source accessory, thereby turning
the switch on, but It avoids the problem that the tact switch needs to be set in different
directions in the past to realize different angles of operation; the tact switch can
recover after the pressure is removed, and will generate thrust to the lamp cover
during the self-recovery process, and the lamp cover and the housing clearance fit.
Therefore, by using the reverse thrust generated by the tact switch on the lamp cover
during the self recovery process of the tact switch, the reverse movement of the lamp
cover in the clearance is well realized, thereby realizing the switch reset and reducing
the need for the return spring and other components. The design not only makes the
structure simple, but also reduces production costs.

DETAILED DESCRIPTION OF THE INVENTION
[0012] 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.
[0013] 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.
[0014] 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.
[0015] 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.
[0016] 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.
[0017] 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:
[0018] 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.
[0019] 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.
[0020] 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.
[0021] 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.
