Description
本发明有关于一种节能植物照明系统,尤其是指一种能拉高瞬间所产生的光量,提高植物光合作用效率,其整体平均消耗功率却未增加,以达到降低能源消耗、省电,而在其整体施行使用上更增实用功效特性者。The invention relates to an energy-saving plant lighting system, in particular to an energy-saving plant lighting system that can increase the amount of light generated instantaneously and improve the photosynthetic efficiency of plants without increasing the overall average power consumption, so as to reduce energy consumption and save electricity, and Those that have more practical efficacy characteristics in their overall implementation and use.
按,各种植物在生长过程中由于所需要的环境、温度、湿度、光照等皆不尽相同,使得若将一般经济作物采用露天方式进行种植,该作物会受到温度、湿度、雨水等天候因素限制,造成作物长势受到影响,甚至于导致作物的产量不佳,更由于一般经济作物无法抵抗较高或较低的极端气温,而容易有死亡状况产生；也因此,即常可见到搭建有各类封闭环境的培育空间,以利用该封闭的培育空间控制光照、温度、湿度等植物生长条件,而可让所种植的植物获得其生长所需的适当环境。According to the fact that various plants need different environments, temperature, humidity, light, etc. during the growth process, if general economic crops are planted in the open air, the crops will be affected by weather factors such as temperature, humidity and rain. Restrictions will affect the growth of crops, and even lead to poor crop yields, and because general economic crops cannot resist higher or lower extreme temperatures, they are prone to death; A cultivation space similar to a closed environment can be used to control plant growth conditions such as light, temperature, and humidity by using the closed cultivation space, so that the planted plants can obtain the appropriate environment required for their growth.
其中,在该培育空间内,由于光照的不足,使得皆会另行设置有发光灯具进行照明,以提供植物足够的光照；请参阅图3现有的发光灯具结构示意图所示,该发光灯具2主要系设有驱动电路21,于该驱动电路21则连接有发光模块22,使得其在使用时,假设该驱动电路21以20w驱动该发光模块22,该发光模块22的亮度为15w,其发光效率为110lm/w,使得该发光模块22的光通量为1650流明(lm),于照射在植物上时,植物所获得的光合作用光子通量(photosynthetic photon flux,PPF)为28μmol/s(请再一并参阅图4现有的发光模块驱动状态示意图所示),其光合作用光子效率(Photosynthetic Photon Efficacy,PPE)则为1.83μmol/j,而让植物可获得光照进行成长。Wherein, in the cultivation space, due to the lack of light, additional lighting lamps will be provided for lighting, so as to provide sufficient lighting for the plants; please refer to the schematic diagram of the existing lighting lamps in FIG. The system is provided with a driving circuit 21, and a light-emitting module 22 is connected to the driving circuit 21, so that when it is in use, assuming that the driving circuit 21 drives the light-emitting module 22 with 20w, the brightness of the light-emitting module 22 is 15w, and its luminous efficiency is 110lm/w, so that the luminous flux of the light-emitting module 22 is 1650 lumens (lm), and when irradiated on plants, the photosynthetic photon flux (PPF) obtained by the plants is 28 μmol/s (please refer to 4), the photosynthetic photon efficiency (PPE) is 1.83 μmol/j, which allows plants to obtain light for growth.
然而,上述发光灯具虽可达到提供植物生长所需的光照的预期功效,但也其实际操作施行使用上发现,该发光灯具系令驱动电路驱动发光模块保持恒亮状态,相对即造成该发光模块呈一持续耗电状态,导致该发光灯具在数用过程中的耗电量极为可观,对于使用者系为一较大的负担,致令其在整体结构设计上仍存有改进的空间。However, although the above-mentioned light-emitting lamp can achieve the expected effect of providing the light required for plant growth, it is also found in the actual operation and use that the light-emitting lamp keeps the driving circuit driving the light-emitting module to maintain a constant brightness state, which relatively causes the light-emitting module to maintain a constant brightness state. In a continuous power consumption state, the power consumption of the light-emitting lamp during several uses is extremely considerable, and it is a heavy burden for the user, so that there is still room for improvement in the overall structural design.
缘是,发明人有鉴于此,秉持多年该相关行业的丰富设计开发及实际制作经验,再予以研究改良,提供一种节能植物照明系统,以期达到更佳实用价值性的目的者。The reason is that the inventor, in view of this, upholds years of rich experience in design, development and actual production in the related industry, and then conducts research and improvement to provide an energy-saving plant lighting system, in order to achieve the purpose of better practical value.
