Supplement lamp for plant characterized in that the heat recovery unit is used to rise temperature for a specific cultivation area, thereby solving the problem that the temperature is too low due to cold weather or the cultivation environment located in a cold area
The present invention discloses a supplement lamp for plant, comprising an LED light-emitting element installed at a tube shaped lamp holder having a heat transfer fluid flowing therein. Wherein, the tube shaped lamp holder and the LED are encapsulated in a transparent tube shaped lamp housing. The heat generated by the emitted LED is transferred to the tube shaped lamp holder and then is discharged out of the supplement lamp via the heat transfer fluid therein. Preferably, air is used as the heat transfer fluid. Due to the barrier of the tube shaped lamp housing, the heat generated by the emitted LED does not result in heat convection with the cultivation environment or directly affects the cultivated plants. Another embodiment further comprises a heat recovery unit. Wherein, the heat transfer fluid after heat absorption is guided to the heat recovery unit, and the heat collected by the heat recovery unit is used to rise temperature for a specific cultivation area, thereby solving the problem that the temperature is too low due to cold weather or the cultivation environment located in a cold area.一種植物補光燈,包括:LED發光元件,LED發光元件裝設於內部流通有熱傳流體的管狀燈座,管狀燈座和LED一併被封裝於透明的管狀燈殼之中,LED發光時產生的熱量傳遞至管狀燈座,再藉由其中的熱傳流體將熱量排出補光燈,較佳地是採用空氣為熱傳流體,由於管狀燈殼的阻隔,LED發光時產生的熱量不會和栽培環境發生熱對流或是直接影響栽培的植物;在另一實施例還包括熱回收單元,吸熱後的熱傳流體被引導至熱回收單元,再藉由熱回收單元收集的熱量對特定的栽培區域增溫,可以解決栽培環境因為地處寒冷地區或寒冷天候的溫度過低的問題。10‧‧‧植物補光燈11‧‧‧電源供應單元12‧‧‧LED發光條13‧‧‧管狀燈殼30‧‧‧管狀燈座301‧‧‧入口302‧‧‧出口31‧‧‧導流管32‧‧‧驅動器
