Circuit diagram of lighting device 200

Hereinafter, it demonstrates using drawing.
1 is a perspective view of a cane lighting device 100, FIG. 2-1 is a cross-sectional view of the pressure-sensitive switch OFF state of FIG. 1u-u ', and FIG. 2-2 is a cross-section of the pressure-sensitive switch ON state of FIG. FIG. 3 and FIG. 3 are circuit diagrams of the cane lighting device 100.
Example 1 has a fixed part 1 having an L-shaped convex part 1L, a light emitting part 2, a main body 3 having an upper L-shaped convex part 3La and a lower L-shaped convex part 3Lb, a spring 3B, an LED light source 2L and reflection. A battery case 4 having a mirror 2M and a step-up circuit 6 and storing a battery, a power switch 5D, a pressure sensitive switch 5K, rubber feet G, and a guard plate TSS are schematically configured.

The luminaire 100 has a casing made up of the fixed portion 1 fixed to the shaft TS, the main body 3 fitted to the fixed portion 1, and the light emitting portion 2 screwed to the main body 3, and the cane shaft TS moves up and down. The pressure sensitive switch 5K is turned on and off by the extension and compression of the spring 3B.
That is, in the state where the power switch 5D is ON and the stick is protruded, that is, the rubber foot G is grounded (hereinafter referred to as grounding), the disk-type pressure sensitive sensor provided above the light emitting unit 2 is used. When the switch terminal 5Ka and the terminal 5Kb of the pressure sensitive switch fixed to the tip of the shaft are separated, the LED light source 2L is not turned on. (Figure 2-1)
When the rubber foot G is in a floating state (hereinafter referred to as non-grounding), the fixed portion 1 is moved upward in the operation space 1S by a spring force, that is, the main body 3 and the main body 3 are screwed. The combined light emitting section 2 is moved downward, and the disk-type pressure sensitive switch terminal 5Ka provided above the light emitting section 2 and the pressure sensitive switch terminal 5Kb fixed to the tip of the shaft are joined and turned on, and the LED light source 2L lights up. (Figure 2-2)

The battery case 4 having the LED light source 2L, the reflecting mirror 2M, and the step-up circuit 6 is fixed to the guard plate TSS by an extension of the reflecting mirror 2M. The distance of the light emitting unit 2 does not change.
The guard plate TSS disperses and relaxes the pressure applied to the light emitting part 2 when the cane is pushed.
In addition, the battery case 4 includes a step-up circuit 6 in which measures to reduce the luminance of the light source due to a voltage drop due to battery consumption and to maintain stable luminance are achieved. (Figure 3)
In addition, since the light emitting unit 2 mainly illuminates the direction of the tip of the cane, if the tip of the cane is swung forward by the way of swinging the cane, the front is widely illuminated with moderate brightness, and the ground is brightly illuminated as it approaches. The purpose is to provide efficient lighting that effectively uses light from a light source with power consumption.

The cane that is provided with the lighting device 100 and has a glowing wand has the power switch 5D turned on, and when the ground is touched, the pressure sensitive switch 5K is turned off and the LED light source 2L is turned off to reduce battery consumption. Next, until the stick is pushed, the pressure sensitive switch 5K is turned on, the LED light source 2L is turned on, and the front is brightly illuminated to prevent the accident.
In addition, since the operation with the wand is generally half or 4: 6 or more and the grounding time, that is, the grounding time that does not necessarily require illumination, is longer, the LED light source 2L is turned on only during the non-grounding time that requires illumination by the pressure sensitive switch 5K. By turning on the light (hereinafter referred to as “lighting when necessary”), the battery lasts longer, and the light source provided at the tip of the cane effectively illuminates the front to prevent the accident.

In addition, the glowing cane can be turned off at the time of grounding if the cane is grounded, for example, when a person using the cane takes a break during a walk, and the LED light source 2L is turned off. It is not necessary to turn the power switch on and off each time in order to prevent wasteful use.
In addition, even if you forget to turn off the power switch after use, the cane that has become a glowing cane is placed on an umbrella stand or a stick stand in a grounded state, and the pressure-sensitive switch is turned off by its own weight. It can be prevented.

4 is a perspective view of the cane lighting device 200, FIG. 5A is a cross-sectional view of the pressure-sensitive switch 15K in FIG. 4V-V ′, and FIG. 5B is a cross-sectional view of the pressure-sensitive switch 15K in FIG. FIG. 6 is a circuit diagram of the lighting device 200. FIG.
The second embodiment includes a shaft TS, a fixing portion 1, a light emitting portion 2, a main body 3, a spring 3B, LED light sources 2L and 12Lb, a reflecting mirror 2M, a step-up circuit 6 and a battery case 4 storing a battery and a power switch. It is schematically constituted by a pressure sensitive switch 15K using 5D, a reed switch, a rubber foot G, and a guard plate TSS.

The illuminator 200 is turned off when the power switch 5D is turned on as a measure for relieving anxiety due to the non-contact reed switches 15Ka and 15Kb used as the pressure sensitive switch 15K and no lighting when the cane is grounded. Since it is the same as the embodiment 100 except that the LED light source 12Lb that does not go through the pressure sensitive switch is provided until it is turned off (hereinafter referred to as “always-lit” or “always-on”). And the code | symbol of an overlap part is shared.
When the power switch 5D is turned on regardless of the grounding or non-grounding, the lighting device 200 turns on the LED light source 12Lb of the normal light to illuminate the front and the surroundings with moderate brightness. The magnet 15Kb provided in the section is located in the OFF region of the reed switch 15Ka, and the LED light source 12Lb is not lit. (Figure 5-1)

Further, when the ground is not grounded, the magnet 15Kb provided at the tip of the shaft TS is moved to the ON region of the reed switch 15Ka by extension of the spring 3B, the reed switch 15Ka is turned on, the LED light source 2Lb is turned on, The accident is prevented by brightening the front with brightness obtained by adding the light of the LED light source 2Lb to the light of the LED light source 2L and illuminating the surroundings with appropriate brightness. (Figure 5-2)
The cane illuminators 100 and 200 are convenient and economical because a normal cane without a light emitting function can be converted into a glowing cane by a simple modification that can replace the replacement rubber, that is, a modification that can be used instead of a rubber foot. Is something.

The lighting fixtures 100 and 200 can be fixed to a shaft from the beginning as a glowing cane to form a completed glowing cane.
In this case, the present invention changes other than the position of the light source, for example, moves the battery or power switch to the handle portion of the cane, makes it possible to repeatedly charge using the secondary battery, and changes the member used or attaches the member. Does not prevent the position from changing.

  In the present invention, the lighting device is converted into a cane that shines on an ordinary cane by simple post-processing, and the tip of the cane is brightly illuminated, thereby confirming the safety of the sticking position of the cane and providing for the prevention of the accident.
