Description

[Detailed description of the invention] [Technical field] This invention relates to a lighting device in which a portable lighting device that can be used in the event of a power outage is detachably attached to a lighting device that is equipped with a light source that operates on AC power. .

[Background technology]

Generally, a lighting device such as a desk lamp is constructed by connecting a base and a shade with a flexible pipe, and disposing a light bulb inside the shade.

This desk lamp is usually used for children's learning.
It is used to light the desk surface, but if the AC power supply is stopped for some reason, the desk lamp will turn off and the room will be pitch black.

For this reason, there is a problem in that the children are not only shaken greatly, but also tend to be at risk of colliding with walls, pillars, etc. when moving outside the room.

Further, portable flashlights are often installed in a separate location from the desk lamp, and the same problems as described above arise when moving the flashlight to such a location.

For this reason, a portable light with a flashlight connected can be connected to the main body of the desk lamp, and in the event of a power outage at night, the portable light and flashlight can be turned on at the same time for illumination, and can also be removed from the main body of the desk lamp and used separately. A version (Jetko Kosho 47-10154) has also been proposed. However, such a desk lamp with an emergency portable light simply connects a portable light circuit including a miniature bulb via a relay contact so as to switch to a battery power circuit in the event of a power outage, so the portable light circuit is always turned on at the same time. It is necessary to keep
Therefore, if you forget to turn on the night bulb or intentionally turn it off at night, you will not be able to find out where it is in the event of a power outage, which has the disadvantage that you will not be able to react in time in case of an emergency.

[Disclosure of invention]

In view of these points, this proposal provides a lighting device that can display the location of portable lighting equipment in the event of an AC power outage and reduce the dangers associated with moving in the dark. A recess is formed in a part of the main body of the device, an insulating protrusion is attached to the recess so that it can move forward and backward, and a light source that is powered by an AC power source is installed, and the device operates according to the power supply status of the AC power source. a lighting device including a first actuating body that operates, and a light source that is powered by a battery; A portable lighting device is provided with a display section that operates based on the body, and a switch that is opened and closed by a projecting body is connected to a battery-powered lighting circuit for a light source, and a portable lighting device is provided in the recess of the lighting device. The lighting device is characterized in that the lighting device is detachably stored and that a switch is opened by a protruding body in connection with the storage.

According to this invention, even if the light source of the lighting equipment goes out due to a power outage of the AC power supply, the first
Since the display unit performs a display operation based on the state of non-coupling with the actuating body, the installation location of the portable lighting device can be easily confirmed.

Moreover, since this portable lighting device is housed in the recess of the lighting device, it can be quickly put to use in the event of a power outage.

Moreover, the portable lighting device is stored in a recessed part of the lighting device so that it can be attached and removed freely, so when moving outdoors, it can be detached from the lighting device and used as a flashlight. Risk can be reduced.

Furthermore, since the insulating protrusion is attached to the recess of the lighting fixture so that it can move forward and backward, the switch can be automatically opened when the portable lighting equipment is stored in the recess. The opening/closing operation can be easily adjusted by moving the protruding body back and forth.

[Best form for implementing the idea]

Next, an example of application of the present invention to a desk lamp will be described with reference to FIGS. 1 and 2.

In the figure, 1 is a desk lamp (lighting device), for example, a base (apparatus main body) 2 and a shade 3.
and a flexible pipe connecting the base 2 and the shade 3. In the lower part 2a of the base 2, there is a light bulb (light source) L ₁ in the shade 3.
Switch SW ₁ is installed to make the light blink. Further, a recess 4 is formed in the upper part 2b of the base 2, and a protrusion 5 is formed on the upper inner wall surface of the recess 4.
Holes 6 are formed in the bottom surface 4a, respectively. A light emitting diode (first operating body) PD ₁ is fixed to the inside of the base on the bottom surface 4 a of the recess 4 so that its emitted light is projected into the recess through the hole 6 . An insulating protrusion (for example, a resin screw) 7 is attached to a portion adjacent to the light emitting diode PD ₁ so as to be movable forward and backward. A portable lighting device 8 is removably housed in the recess 4.

This portable lighting device 8 has a concave reflecting plate 10 and a glass plate 11 fixed to one end of a case 9 made of an insulating material, for example, with a cap 12 having a window hole in the center. It consists of a light bulb (light source) L ₂ installed. A small hole 13 is formed in a portion of the reflecting plate 10 excluding the central portion so that the light emitted from the light emitting diode (display portion) PD ₂ is projected to the outside. Incidentally, this light emitting diode PD ₂ can also be arranged at an appropriate location so that its light emitting portion is exposed from the case 9.
Further, holes 14 and 15 are formed in the bottom 9a of the case 9, a switch SW ₂ having a contact piece is installed around the hole 14, and a phototransistor (second operating body) PT is installed around the hole 15. Each _R is fixed. For example, a sliding manual switch SW ₃ is disposed on the side surface 9b of the case 9 so that its operating portion SW ₃₀ protrudes outward.

On the other hand, the electric circuits of the desk lamp 1 and the portable lighting device 8 are constructed as shown in FIGS. 3a and 3b, for example. Desk lamp 1 is AC power source
The light bulb L ₁ is connected in series through the switch SW ₁ , and the capacitor is connected to the AC power source AC.
C ₁ , constant voltage diode ZD, light emitting diode PD ₁
A parallel circuit of _R1 and a series circuit of a diode D are connected. Portable lighting device 8 connects light bulb L ₂ to battery B via switches SW ₂ and SW ₃ .
is connected to the battery B, and a series circuit consisting of a resistor R ₂ and a phototransistor _PTR , a resistor R ₃ , a light emitting diode PD ₂ , and a transistor are connected to the battery B.
The series circuit with T _R is connected in parallel, and the resistor R ₂
The connection point between the phototransistor _PTR and the phototransistor PTR is connected to the base of the transistor _TR .

Next, the operation of this desk lamp will be explained. First, as shown in Figure 4, a desk lamp 1
A portable lighting device 8 is stored in the recess 4 of the device. As a result, the operating part SW ₃₀ of the manual switch SW ₃ is pushed by the protruding part 5 and is forcibly switched to the ON state position shown by the solid line in _FIG . The piece is pushed into the OFF state by a protrusion 7 attached to the bottom surface 4a and protruding inward. In this state, when the plug of the cord extending from the desk lamp 1 is inserted into the outlet, a constant voltage regulated by the constant voltage diode ZD is applied to the capacitor _C1 , and based on this voltage, the light emitting diode
PD ₁ starts emitting light. The emitted light from the light emitting diode PD ₁ passes through the hole 6 of the recess 4 and is connected to the phototransistor.
_The phototransistor _PTR becomes conductive. Therefore, the transistor _TR becomes non-conductive and the light emitting diode PD ₂ does not emit light. Then, by closing the switch _SW1 , the light bulb _L1 is turned on, and a desired area, for example, the desk surface is illuminated.

If the AC power supply is stopped for some reason, the light bulb _L1 will turn off and the light emitting diode will turn off.
PD ₁ stops emitting light. This causes the phototransistor _PTR to become non-conductive. Then, the base current flows through the transistor _TR via the resistor _R2 , so that the transistor _TR becomes conductive. As a result, a current flows from the battery B through the resistor _R3 to the light emitting diode _PD2 , so that the light emitting diode PD2 emits light. The light emitted from the light emitting diode PD ₂ is projected to the outside through the small hole 13 of the reflection plate 10. Therefore, even if the room is completely dark, the location where the portable lighting device 8 is installed can be easily and reliably displayed. and,
As shown in FIG. 2, when the portable lighting device 8 is removed from the recess 4 of the desk lamp 1, the contact piece of the switch SW ₂ is closed by being pressed by a spring or the like, and the light bulb L ₂ is turned on. do. then the light bulb
The blinking of L ₂ is the operation part of manual switch SW ₃ .
Performed by SW ₃₀ . That is, if you want to turn off the light, you can move the operating section SW ₃₀ to the dotted line position in the figure.

FIG. 5 shows another embodiment of the desk lamp, in which the recessed portion 4 is formed to slightly protrude forward from the upper portion 2b of the base 2. In addition, the operating section of the manual switch SW ₃ of the portable lighting device 8
SW ₃₀ is forcibly inserted using the opening edge of recess 4.
Switched to ON state. Incidentally, in order to regulate the direction in which the portable lighting device 8 is housed in the recessed portion 4, the portable lighting device 8 and the recessed portion 4 may be provided with projections and depressions.

FIG. 6 shows another embodiment of the electric circuit, in which the light emitting diode PD ₁ in FIG. 3 is replaced with a magnet coil MC, and the phototransistor _PTR is replaced with a reed switch MCS. When AC power supply AC is supplied, reed switch MCS is closed by excitation of magnet coil MC, and the same operation as shown in FIG. 3 is performed. In this electric circuit, an overturning switch can be connected in series to the switch _SW1 , or a series circuit of a light emitting diode, a diode, and a resistor can be connected in parallel to these switches. Particularly in the latter case, since the light emitting diode emits light when the switch SW ₁ is turned off, the location of the switch SW ₁ can be easily confirmed even if the room is completely dark.

In addition, in the present invention, in addition to a desk lamp, ceiling fixtures, wall-mounted fixtures, etc. can also be used as lighting fixtures. Further, a fluorescent lamp can also be used as the light source. Further, as the first and second actuating bodies, a combination of a light emitting diode, a phototransistor, a magnet, a reed switch, a magnetism, a Hall element, etc. can be used. Further, the manual switch may be a push type instead of a slide type, or may be omitted. Furthermore, the display section is not limited to only light emitting diodes, and the circuit configuration can be changed as appropriate.
