Description
本考案は、温度検出部と多色発光ダイオードの組み合わせによって空気中及び水中の温度を光によって表示する温度表示器に属する。 The present invention belongs to a temperature indicator that displays the temperature in air and water with light by a combination of a temperature detector and a multicolor light emitting diode.
従来の温度表示は、水銀や特殊溶液の温度に伴う伸縮によって表示されるものや、温度検出部によって検出された温度をデジタル数字に置き変えて表示していた。 Conventional temperature displays are displayed by the expansion and contraction associated with the temperature of mercury or special solution, or the temperature detected by the temperature detection unit is replaced with digital numbers.
従来の温度表示方法は、温度表示計の近くまで寄って目視確認しないと、その時々の温度を把握出来なかった。大型のデジタル表示の温度表示計もすでに存在するが、やはり遠目での確認並びに夜間や未照明の状況にあっては即座に現状温度を確認することが出来なかった。 The conventional temperature display method cannot grasp the temperature at that time unless it is close to the temperature indicator and visually confirmed. There is already a large digital temperature indicator, but it was not possible to confirm the current temperature immediately at night or without lighting.
まず、赤色、緑色及び青色発光色素からなる多色発光ダイオードにおいて、色彩工学の知見に基づき、波長の短い光は寒色に、波長の長い光は暖色に、それぞれ色相を定義づける。
可視光域の下限波長（３８０ｎｍ）から上限波長（７８０ｎｍ）を色彩表示域とし、温度検出部の測定結果の分解能に応じて、紫⇒青⇒緑⇒黄色⇒赤へと変換表示される。First, in a multicolor light emitting diode composed of red, green, and blue light emitting dyes, based on knowledge of color engineering, a hue is defined as light having a short wavelength in a cool color and light having a long wavelength in a warm color.
The color is displayed from the lower limit wavelength (380 nm) to the upper limit wavelength (780 nm) in the visible light range, and is converted from purple to blue to green to yellow to red according to the resolution of the measurement result of the temperature detector.
それぞれの発光色には受け持ちの温度帯を設定し、温度検出部で検出された温度に対応する色彩光が表示される。 Each emission color is set with a temperature range, and color light corresponding to the temperature detected by the temperature detection unit is displayed.
ユーザーニーズにより、予め任意の温度と発色光を設定することも可能である。 It is also possible to set an arbitrary temperature and colored light in advance according to user needs.
温度検出部は、温度センサー周辺の大気中及び水中の温度を検出して測定する。
測定温度はマイコン内で発色データへ変換され、発光色が定められる。The temperature detector detects and measures temperatures in the air and water around the temperature sensor.
The measured temperature is converted into color data in the microcomputer, and the emission color is determined.
電源である乾電池の電圧低下による多色発光ダイオードの発色ぶれを防止するため、一定電圧に保つ回路を併設すると共に、一定電圧を下回った時は機能を強制的に停止する。 In order to prevent color fluctuation of the multi-color light emitting diode due to the voltage drop of the dry battery as a power source, a circuit that keeps the voltage constant is also provided, and the function is forcibly stopped when the voltage drops below the voltage.

各部名称は、以下のとおりである。
ａ．温度検出部
ｂ．温度−電圧変換回路
ｃ．マイコン
ｄ．ＬＥＤ発光部
ｅ．スイッチ入力安定化回路

ｇ．動作電圧判別回路The names of each part are as follows.

温度検出部においては、センサーに接触する大気及び液体の温度を検出し計測する。 The temperature detection unit detects and measures the temperature of the atmosphere and liquid in contact with the sensor.
温度−電圧変換回路及びマイコン部においては、計測された温度を色表示データにに変換する。 In the temperature-voltage conversion circuit and the microcomputer unit, the measured temperature is converted into color display data.
ＬＥＤ発色部においては、色表示データに対応する色彩光を発光する。 The LED coloring section emits color light corresponding to the color display data.
スイッチ入力安定回路においては、ノイズを除去するとともに、スイッチ操作時のチャタリングの影響を防止する。 In the switch input stabilization circuit, noise is removed and the influence of chattering during switch operation is prevented.
電圧安定回路においては、乾電池から供給された電流の電圧を一定幅内に収まるよう制御する。 In the voltage stabilization circuit, the voltage of the current supplied from the dry battery is controlled so as to be within a certain range.
動作電圧判別回路においては、電源から供給される電流の電圧が一定値を下回った段階で、全回路への電流の供給を停止し、誤発色を防止する。 In the operating voltage discriminating circuit, when the voltage of the current supplied from the power source falls below a certain value, the supply of current to all the circuits is stopped to prevent erroneous color development.
本考案は、遠目でも暗闇でも、発光ダイオードの発する鮮明な光によって現状の温度確認が出来るものであり、従来の目視確認の煩雑性を克服できる。
また、急性疾病を引き起こす冬場のお風呂場やトイレなどに設置することにより、未然に事故防止することが可能である。育児や老人介護の現場においても、誰にでもすぐ分かる温度管理手段として有用である。In the present invention, the current temperature can be confirmed by vivid light emitted from the light emitting diodes even in the distance or in the dark, and the complexity of conventional visual confirmation can be overcome.
In addition, it is possible to prevent accidents by installing them in winter bathrooms and toilets that cause acute illness. It is also useful as a temperature control means that anyone can understand immediately, even in the field of childcare and elderly care.
