This invention is a health-care device providing wrist light therapy by far-infrared ray, LED or LASER light, which is capable for wearing on the wrist. The device comprises a main body and at least one bendable band connected to the main body. A power source, a control circuit, a display, and a far-infrared ray, LEDs or LASER emitting units are arranged in the main body or on the belt. The control circuit is electrically connected to the power source. The display is set at the front side of the main body and electrically connected to the control circuit and the power source. The light emitting unit is arranged at the rear side of the main body and electrically connected to the control circuit and the power source. Therefore, the device may be worn on the wrist so as to emit far-infrared ray, visible light or laser (such as He-Ne laser) light to acupoints and arteries at the wrist for health care at anytime and anywhere. It is easy to use and convenient to operate. It may also save space without preparing large size equipment.本發明為一種手腕部光線保健裝置,可穿戴在人體的手腕部,包括主體;至少一帶體,連接在主體左右兩側邊,並可任意彎曲;電源,設置在主體內;控制電路,設置在主體內,並與電源電性連接;螢幕,設置在主體前側面,並與控制電路及電源電性連接;以及遠紅外線、光發射二極體或雷射發射單元,設置在主體後側面或帶體上,並與控制電路及電源電性連接;藉此,可以穿戴在手腕上,隨身隨處即可進行非侵入性之光能量保健處理,而且操作方式簡便,更無需佔用空間放置儀器,更可結合於智慧型穿戴裝置或登山錶等裝置(前述已經說明可以穿戴在手腕上,此處無須再說明,因為已經超過摘要規定的字數),達到兼顧偵測生理訊號及積極保健之功效。100‧‧‧手腕部光線保健裝置1‧‧‧主體2‧‧‧帶體3‧‧‧電源4‧‧‧控制電路41‧‧‧計時單元42‧‧‧記憶單元6‧‧‧光能量發射單元7‧‧‧控制開關
