  How to decide on the best high mast led lighting ? High mast led lighting is a part of outdoor lighting offering specifically installed to illuminate large spaces like parking lots, stadiums, shipyards, manufacturing plants, heritage sites, etc. These lighting solutions are an integral part of urban planning and public infrastructure facilities that can help in accentuating outdoor spaces with the right levels of illumination. Moreover, they ensure safety of the people in vulnerable spaces and can enrich audience’s experience in places like sports stadiums. high mast led light s come in a variety of shapes, sizes and designs. However, it is essentially important that you decide on outdoor commercial lighting strictly as per the needs and requirements of the space. For instance, industrial floodlights have always been one of the most popular choices when it comes to lighting vulnerable places like shipyards and manufacturing plants. Here are some important points you should consider

Artificial light(LED Grow Lights) can be used for plant growth in three different ways: 1. To provide all the light a plant needs to grow 2. To supplement sunlight, especially in winter months when daylight hours are short. 3.To increase the length of the "day" in order to trigger specific growth and flowering. Here are several reasons why you may choose to grow your leafy greens under led lights. 1- you may not have a readily accessible sunny window ledge or you may not have enough of them. I have a kitchen window ledge that gets good sun in summer but very little in winter. 2- using our desk light series you can use the lights to grow your sprouts as well as light the work area of the desk(the shade rotates to adjust the spread of light). A great break from work to look up and see your salad growing in front of you, or on your kitchen bench shedding extra light on your chopping board.. 3-you may

标签： LED 植物 照明 LED用于植物生长照明的探讨 LED用于植物生长照明的探讨 作者： Panic 2007年6月18日 前几天做了 水族灯 ，除了对电路部分做了研究之外，对实际的照明效果也做了观察。 经过一周的持续照明，鱼缸中的水草并没有明显的生长，相反的，水草的色泽反而变淡了。 我查阅了一些关于植物光照需求方面的资料，基本的，以下的观点被广泛认可： 1，植物光合作用需要的光线，波长在400 ~ 700nm左右。 2，不同波长的光线对于光合作用的影响是不同的，400 ~ 520nm（蓝色）的光线以及610 ~ 720nm（红色）对于光合作用贡献最大。 3，520 ~ 610nm（绿色）的光线，被植物色素吸收的比率很低。 这些观点源自一篇名为“Photo morphogenesis in Plant”的论文，作者是R. E. Kendrick 和G. H. M. Kronenberg (1986年,Martinus Nijhoff Publishers)。 按照这些原理，市面上销售的植物灯，都提供红兰两种波长的光线，覆盖光合作用所需的波长范围。视觉效果上，植物灯都呈现粉红色。 而现有白光LED，最普遍的是使用蓝色核心，激发黄色荧光粉，由此复合产生视觉上的白光效果。能量分布上，在445nm的蓝色区和550nm的黄绿色区存在两个峰值。而植物所需的610 ~ 720nm红光，则非常缺乏。 这就解释了为什么在白光LED照射下，植物生长不利。 为了能够有效促进植物生长，光源必须提供恰当波长的光线，以下是不同颜色LED所发射光线的波长表： royal blue 品蓝：445nm 440nm~460nmblue 蓝色：470nm 460~490nmcyan 青色：505nm 490~520nmgreen 绿色 :530nm 520~550nmred 红色：627nm 620~645nmred-orange: 617nm 613~620nmamber:琥珀色 590nm 585~597nm 从这个表中，我们不难发现，蓝色(470nm)和红色(627nm)的LED，刚好可以提供植物所需的光线，因此，LED植物灯，比较理想的选择就是使用这两种颜色组合。 实际上，就在我研究这个问题的同时，国外已经有相关的产品上市，详见： ht
