Abstract
An illuminating device includes a casing having a movable module movably received therein. A first spring is biased between a first end of the movable module and an inside of the close end of the casing. An illuminating member is connected to a second end of the movable module and located in the open end of the casing. A circuit board is connected to the illuminating member and a second spring is biased between the circuit board and a plurality of batteries. A switch device is connected to the batteries and has a button extending from the first end of the movable module. When pushing the second end of the movable module, the button is compressed by the inside of the casing to turn on the illuminating member.
Description
FIELD OF THE INVENTION
The present invention relates to an illuminating device having a movable module received in a casing and when the movable module is pushed, a switch device is activated to turn the illumination member.
BACKGROUND OF THE INVENTION
A conventional illuminating device known to applicant is shown in FIG.
1
and is connected to a top section of a pen. A light
11
is received in the top end of the pen and a rotatable casing
10
is rotated by the user to turn on the light
11
. This type of the illuminating device actually is operated by two hands, one hand holding on the lower section, the pen section, and the other hand rotating the rotatable casing
10
. This is not convenient for the user because two hands are required to operate it. The other type of conventional illuminating device is shown in FIG.
2
and includes a button
13
connected on the casing
12
so that the user uses only one hand can turn on the light
14
. However, the button
13
has to be pressed all the way to keep the light
14
being operated.
SUMMARY OF THE INVENTION
In accordance with one aspect of the present invention, there is provided an illuminating device which comprises a casing having an open end and a close end. A movable module is movably received in the casing and a first spring is biased between a first end of the movable module and an inside of the close end of the casing. An illuminating member is connected to a second end of the movable module and located in the open end of the casing. A circuit board is connected to the illuminating member and a second spring is biased between the circuit board and a plurality of batteries. A switch device is connected to the batteries and a button extending from the first end of the movable module.
The primary object of the present invention is to provide an illuminating device that has a movable module received in the casing so that the whole structure of the illuminating device is simplified.
The present invention will become more obvious from the following description when taken in connection with the accompanying drawings which show, for purposes of illustration only, a preferred embodiment in accordance with the present invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring to
FIGS. 3
to
6
, the illuminating device
20
of the present invention comprises a casing
21
having an open end and a close end which is a ball-pen end. A movable module
30
is movably received in the casing
21
and a first spring
61
is biased between a first end of the movable module
30
and an inside of the close end of the casing
21
. An illuminating member
40
is connected to a second end which is an open end
31
, of the movable module
30
and located in the open end of the casing
21
. A circuit board
50
is connected to the illuminating member
40
and a second spring
60
is biased between the circuit board
50
and a plurality of batteries
70
. A switch device
80
is connected to the batteries
70
and a button
81
extending from an opening
32
defined in the first end of the movable module
30
. The first spring
61
is mounted on the button
81
of the switch device
80
and a rod extending from the inside of the close end of the casing
21
.
When pushing the second end of the movable module
30
, the button
81
is moved to be compressed so as to let the illuminating member
40
turn on. It is to be noted that a lens and/or a pattern plate can be engaged with the open end
31
of the movable module
30
so as to obtain an variable or colorful illusion.
As shown in
FIGS. 7 and 8
, another embodiment of the illuminating device
20
comprises a conductive casing
21
having an open end and a close end which is a ball-pen end. A movable module
30
movably received in a plastic tube
90
which is movably received in the casing
21
. A conductive member
80
is connected to a first end of the movable module
30
and a first spring
61
is biased between the conductive member
80
and an inside of the close end of the casing
21
. A periphery of the conductive member
80
movably contacts an inside of the conductive casing
21
. An illuminating member
40
is connected to a second end of the movable module
30
and located in the open end of the casing
21
. A circuit board
50
is connected to the illuminating member
40
and a second spring
60
is biased between the circuit board
50
and a plurality of batteries
70
. A conductive cup
92
is connected to the second end of the movable module
30
and will be moved to contact the conductive casing
21
when being pushed. A lens
94
and a pattern plate
95
are connected to the conductive cup
92
. Therefore, when pushing the conductive cup
92
to contact the conductive casing
21
, the illuminating member
40
turns on.
The movable module
30
includes two sections and a non-conductive ring
91
is mounted to the circuit board
50
and located between the two sections of the movable module
30
. The non-conductive ring
91
ensures that the two sections of the movable module
30
is electrically separated. As shown in
FIG. 9
, the illuminating device
20
can be connected to a key ring
100
or any objects.
While we have shown and described the embodiment in accordance with the present invention, it should be clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
