[0002] Lighting devices, such as light tubes, have been widely used in various buildings
so as to provide people with lighting and make people's lives more convenient. Due
to advance of technology, the efficiency of light-emitting diodes (LEDs) has also
been greatly improved, so most of currently available light tubes adopt LEDs as the
main light sources. LED light tubes have many advantages, such as energy saving, environmental
protection, high efficiency, etc. However, the currently available LED light tubes
do not provide effective anti-shock protection, so users often get electric shocks
accidentally when installing the LED light tubes. Therefore, the safety of the currently
available LED light tubes still needs to be further improved.

[0017] Please refer to FIG. 1, which is an exploded view of a light tube with anti-electric
shock mechanism in accordance with one embodiment of the present invention. As shown
in FIG. 1, the light tube 1 includes an end cap 11, a driving module 12, an interlocking
mechanism 13, a button 14 and a light-emitting module 15.
[0018] The end cap 11 includes a cover 11 and a main cap body 112. The cover 111 is disposed
at one end of the main cap body 112. The end cap 11 has a locking slot 1111 disposed
at one end of the end cap 11. In this embodiment, the locking slot 1111 is disposed
on the cover 111. The end cap 11 further has a switch hole 1121 disposed at one side
of the end cap 11. In this embodiment, the switch hole 1121 is disposed on the main
cap body 112.
[0019] The driving module 12 is disposed in the end cap 11 and has a switch 121. In this
embodiment, the driving module 12 is disposed in the main cap body 112. In one embodiment,
the driving module 12 may be a constant-current driving circuit, a constant-voltage
driving circuit or other similar circuits. The circuit structures of the constant-current
driving circuit and constant-voltage driving circuit are already known by those skilled
in the art, so will not be described herein.
[0020] The light-emitting module 15 is disposed at the other end of the end cap 11 and connected
to the driving module 12. The light-emitting module 15 includes a housing 151, a circuit
board 152 and a plurality of light-emitting elements 153. The circuit board 152 and
the light-emitting elements 153 are disposed in the housing 151. The light-emitting
elements 153 are disposed on the circuit board 152. In one embodiment, the light-emitting
elements are light-emitting diodes (LEDs) or other similar elements. The functions
and structure of the LEDs are already known by those skilled in the art, so will not
be described herein.
[0021] The interlocking mechanism 13 is disposed in the locking slot 1111 and penetrates
through the locking slot 1111 to enter the inner space of the end cap 11. The interlocking
mechanism 13 includes a wedge-shaped block 131, a supporting plate 132, an interlocking
point 133, two supporting posts 134 and two elastic members 135. The wedge-shaped
block 131 and the supporting posts 134 are disposed at the two ends of the supporting
plate 132. The interlocking point 133 is disposed on the supporting plate 132. The
supporting posts 134 are sleeved with the elastic members 135 respectively. In one
embodiment, the elastic members 135 may be a spring or other similar elements.
[0022] The button is disposed in the end cap 11 and is exposed from the switch hole 1121.
The button 14 has a pressing end 141 and a triggering end 142. The pressing end 141
is exposed from the switch hole 121. The triggering end 142 is disposed in the inner
space of the end cap 11. When an external force is applied to the pressing end 141
(e.g., the user presses the pressing end 141), the triggering end 142 can move in
the direction toward the switch 121 of the driving module 12 so as to trigger the
switch 121.
[0023] The embodiment just exemplifies the present invention and is not intended to limit
the scope of the present invention; any equivalent modification and variation according
to the spirit of the present invention is to be also included within the scope of
the following claims and their equivalents.
[0024] Please refer to FIG. 2, FIG. 3 and FIG. 4. FIG. 2 is a schematic view of a first
operational state of the light tube with anti-electric shock mechanism in accordance
with one embodiment of the present invention. FIG. 3 is a schematic view of a second
operational state of the light tube with anti-electric shock mechanism in accordance
with one embodiment of the present invention. FIG. 4 is a schematic view of a third
operational state of the light tube with anti-electric shock mechanism in accordance
with one embodiment of the present invention. As shown in FIG. 2, when the light tube
1 is not installed on the tube light holder, the elastic member 135 is in balance
state (the elastic member 135 is not compressed), the interlocking mechanism 13 protrudes
from the locking slot 1111 and the interlocking point 133 and the button 14 are arranged
in a straight line. Thus, if the pressing end 141 of the button 14 is pressed by an
external force, the interlocking point 133 can block up the moving path of the triggering
end 142 of the button 14, so the triggering end 142 cannot move in the direction toward
the switch 121 of the driving module 12. Thus, the light tube 1 can be in open-loop
state. Accordingly, in the above state, the interlocking point 133 can limit the triggering
end 142 of the button 14 to move in the direction toward the switch 121. At the moment,
the light tube 1 is in anti-electric shock state.
[0025] As shown in FIG. 3, when the user installs the light tube 1 on the tube light holder,
the interlocking mechanism 13 is pushed by the tube light holder to enter the inner
space of the end cap 11. In this way, the elastic member 135 is in compressed state,
so the interlocking point 133 and the button 14 are not arranged in a straight line.
Therefore, if an external force is applied to the pressing end 141 of the button 14,
the interlocking point 133 does not block up the moving path of the triggering end
142 of the button 14. Thus, the triggering end 142 of the button 14 can move in the
direction toward the switch 121 of the driving module 12. At the moment, the light
tube 1 is in installation state (the light tube 1 has been installed on the tube light
holder).
[0026] As shown in FIG. 4, when the light tube 1 is in installation state, the user can
press the pressing end 141 of the button 14, such that the triggering end 141 of the
button 14 can move in the direction toward the switch 121 in order to trigger the
button 121. At the moment, the circuit of the light tube 1 is in closed-loop state,
so the light tube 1 can enter operating state.
[0027] When the user moves the light tube 1 from the tube light holder, the elastic member
135 returns to balance state again (the elastic member 135 is not compressed). Then,
the interlocking mechanism 13 is pushed out of the inner space of the end cap 11 and
protrudes from the locking slot 11. At the moment, the interlocking point 133 and
the button 14 are arranged in a straight line again. Therefore, the light tube 1 can
return to anti-electric shock state shown in FIG. 2.
[0028] As previously stated, the light tube 1 integrates the interlocking mechanism 133
with the button 14 having the pressing end 141 and the triggering end 142, which can
serve as an effective anti-electric shock mechanism. This anti-electric shock mechanism
can avoid that the user gets electric shock when installing the light tube 1. Accordingly,
the safety of the light tube 1 can be further enhanced.
[0029] The embodiment just exemplifies the present invention and is not intended to limit
the scope of the present invention; any equivalent modification and variation according
to the spirit of the present invention is to be also included within the scope of
the following claims and their equivalents.
[0030] It is worthy to point out that the currently available LED light tubes do not provide
effective anti-shock protection, so users often get electric shock accidentally when
installing the LED light tubes. Therefore, the safety of the currently available LED
light tubes still needs to be further improved. On the contrary, according to one
embodiment of the present invention, the light tube with anti-electric shock mechanism
integrates an interlocking mechanism with a button having a pressing end and a triggering
end, which can serve as an effective anti-electric shock mechanism. This anti-electric
shock mechanism can avoid that the user gets electric shock when installing the light
tube. Accordingly, the safety of the light tube can be further enhanced.
[0031] Also, according to one embodiment of the present invention, the light tube with anti-electric
shock mechanism has the integrated structure formed by the interlocking mechanism
and the button having the pressing end and the triggering end so as to provide the
anti-electric shock function. When the light tube is not installed on the tube light
holder, the light tube can be in open-loop state in order to prevent the user from
getting electric shock.
[0032] Further, according to one embodiment of the present invention, the light tube with
anti-electric shock mechanism can adopt LEDs, so the light tube can achieve many advantages,
such as energy saving, environmentally-friendly and high efficiency. Accordingly,
the light tube can be more comprehensive in use and can satisfy actual requirements.
[0033] Moreover, according to one embodiment of the present invention, the end cap of the
light tube with anti-electric shock mechanism includes a cover and a main cap body.
The cover and the main cap body can be combined with each other via a plurality of
snap-fit hooks and locking blocks. Therefore, the assembly of the light tube can be
more convenient.
[0034] Furthermore, according to one embodiment of the present invention, the structure
design of the light tube is simple, so the light tube can achieve the desired technical
effects without significantly increasing the cost thereof. Thus, the light tube can
have high commercial value. As set forth above, the light tube according to the embodiments
of the present invention can definitely achieve great technical effects.
[0035] Please refer to FIG. 5 and FIG. 6, which are an exploded view and a sectional view
of an end cap of the light tube with anti-electric shock mechanism in accordance with
one embodiment of the present invention. Please also refer to FIG. 1. As shown in
FIG. 1, FIG. 5 and FIG. 6, the end cap 11 includes a cover 111 and a min cap body
112. The cover 111 has a plurality of snap-fit hooks H1 and the main cap body 112
has a plurality of locking blocks H2. The snap-fit hooks H1 can be engaged with the
locking blocks H2 in order to combine the cover 111 with the main cap body 112.
[0036] Via the above structure design, the user can manually combine the cover 111 with
the main cap body 112 without a tool, which can make the installation of the light
tube 1 be more convenient.
[0037] The embodiment just exemplifies the present invention and is not intended to limit
the scope of the present invention; any equivalent modification and variation according
to the spirit of the present invention is to be also included within the scope of
the following claims and their equivalents.
[0038] According to one embodiment of the present invention, the light tube with anti-electric
shock mechanism integrates an interlocking mechanism with a button having a pressing
