回路図を示す。）2. Description of the Related Art In a light-emitting body lighting device using a piezoelectric element that has been conventionally used, power is generated when the piezoelectric element is subjected to a mechanical action, but the piezoelectric element is attenuated thereafter. It is difficult to keep a diode (such as a diode) emitting light. As a way to solve this,
There is a proposal to store the amount of electricity generated by the piezoelectric element in a charger. (Patent Registration 2047033) FIG. 1 shows a circuit diagram of this conventional example.

ある。However, the method of storing electricity has a drawback that circuit components such as a charger and a switching element for storing electricity are required. There is also a drawback that the electric circuit consumes the amount of electricity generated.
【０００４】従って、解決しようとする課題は、発光体
の点灯時間を長く持続できない点がひとつ。もう一点
は、持続させるために電気量を蓄電する方法もあるが、
多くの回路部品が必要になり電気量を回路部品が消費し
て効率が悪いという点である。Therefore, one of the problems to be solved is that the lighting time of the light emitter cannot be maintained for a long time. Another point is that there is a method to store the amount of electricity to sustain it,
This is because a lot of circuit components are required, and the circuit components consume electricity and are inefficient.

点灯装置を提供する。In order to solve the above problems, the present invention causes a light emitting body to emit light by the amount of electricity generated by a piezoelectric element and excites a phosphorescent phosphor with the emitted light. Thus, a light-emitting body lighting device having a long lighting time by the light emission of the phosphorescent phosphor is provided.

る。BEST MODE FOR CARRYING OUT THE INVENTION If the wavelength of a light emitter is visible light, both the light of the light emitter and the phosphorescent phosphor can be used as a lighting device. However, it is also possible to use a light-emitting body that emits ultraviolet light having a wavelength higher than that of visible light. In that case, since the light of the light emitting body is not visible light, it does not contribute to human visual recognition, but since the excitation energy of the phosphorescent phosphor is large, the phosphorescent phosphor can be turned on brightly or for a long time.
【０００７】従来は、圧電素子が発生した電気量を蓄え

方法しかなかった。本発明の解決手段は、「蓄電」でな
くて「蓄光」、すなわち圧電素子の発生した電気量で、
蓄光性蛍光体に光エネルギーを蓄えて点灯時間を長くす
る、と言う全く過去になかった方法である。Conventionally, there has been only a method of increasing the lighting time of the light-emitting body by means of "storage" for storing the amount of electricity generated by the piezoelectric element. The solution means of the present invention is not “storage” but “light storage”, that is, the amount of electricity generated by the piezoelectric element,
This is a method that has never existed in the past, in which light energy is stored in the phosphorescent phosphor to prolong the lighting time.

けで点灯させることができる。On the other hand, it is publicly known only by exciting the phosphorescent phosphor with the light emitted from the light emitting diode.
(JP-A-10-188649, JP-A-11-16341
7, JP-A-2000-164935) However, the method of causing the light emitting diode to emit light has a demerit that a battery or the like needs to be replaced. The present invention can be turned on only by supplying mechanical energy without supplying electric energy from the outside.

る。That is, the present invention utilizes the amount of electricity generated by the "piezoelectric element" to supply the "piezoelectric element" without externally supplying electric energy (eg, a battery).
It is possible to provide a light-emitting body lighting device having a long lighting time by using the "phosphorescent phosphor", which is a problem in that the "lighting time" is short, which is a drawback of using the.
