How to Build a Grow Light Circuit

该帖子讨论了植物的典型种植光电路应用，以便使用多色LED刺激人为点亮的环境中的光合作用效果。杰克先生提出了这个想法。

电路目标

我想向您的网站捐款，并向您付款您在这里的项目。但首先，要从网络上收到个人的钱，您将必须获得一个薪酬PAL帐户。

Once this is established, you will have to decide how you would like to operate it. You provide thousands of people from all over the world with technical information to make there life better, there is no reason not to have a "donate page" to make your life better also.

除非您独立富有。您有网站成本，食物，生活费用，旅行等。

我很乐意与您分享我的项目。您可以将它们发布在您的网站上。在美国，住宅LED灯尚未捕捉到，这有很多理由。

商业照明甚至更糟。对于大多数普通工人阶级的人来说，电力确实是一个大谜，他们认为最好避免使用。

I have several friends who are very successful, and do no know what a "watt" is. That is OK. But not being aware slows down our evolutionary process. The very poor people are the last to enjoy the benefits. The very big corporation have enslaved us all. This will change soon.

我有一个“壮大”项目，我刚刚完成，如果需要，可以向您发送详细信息和照片。我的生长灯是28个LED混合物（红色，蓝色，白色），在大型照明公司中，同样的灯光耗资300美元至500美元。

“ Grow Lights”的最大问题，我敢肯定您知道这是不同颜色的不同远程电压。例如，红色（1.63V-2.03V）和蓝色（2.48V-3.7V）。

在同一电路中具有红色和蓝色，正向电压可能会有1V至1.5V。在我刚刚建造的电路中，我的红灯在1.7V下运行，蓝色在3.5V下运行，这种差异会引起很多热量。

我可以通过将每个电路放在自己的电路上来解决问题，但我不希望这样做。我在每行的一开始都使用16欧姆，10W电阻器（每行7 LED，每行7个LED）。

甚至他们很热。需要平衡该电路。我使用直流电源24V和4AMP来为电路供电。

下一个项目将是我的商店的几个大灯，......... 50-60 LED固定装置。之后，将在仓库中放入高级LED照明 - 办公大楼将是50-200 LED照明灯具。我希望使用120VAC -220VAC提供电源。

是否可以在单个IC芯片上设计LED驱动器电路（LDC）？？？我知道可以做到。如何制作LCD EPROM？

让我知道您是否想发布“生长光实验”。

最良好的问候，
杰克

.....我刚刚发现了为什么我的生长光电路会产生如此多的热量。它不仅是由于红色和蓝色灯光之间的向前电压差，而且是由于我的系列字符串的不平衡引起的。

换句话说，如果每个字符串中有不同数量的蓝光，那么我将加热热量。如果我使每个字符串中的蓝光数量相同，则应使用。您可能已经知道了。

分析the Circuit Request

谢谢杰克，我会为您提供计算系列LED电阻的公式，以便您可以正确平衡LED并从中获得最佳性能

R = (U - Tot.LEDfwdV) / LED current.

在上面的公式中，U是电源电压，TOT.LEDFWDV是特定LED系列的组合或总向前电压值，LED电流是LED AMP额定值。

就红色LED而言，该公式可以通过以下方式解决：

假设U = 24V，FWD电压= 2V，串联= 7中的总数，LED电流= 20mA或0.02AMP

r = {24 - （2x7）}/0.2

=（24 -14）/0.02

= 10/0.02

= 500ohms

可以使用公式计算瓦数

w = tot.ledfwdv x led电流

= 14 x 0.02 = 0.28瓦

您只需要遵循上述LED系列的计算过程，并将计算出的电阻器与特定颜色字符串串联定位。

我希望您这样做不会太困难。如果您有问题，请告诉我。

The circuit diagram for the proposed grow light may be witnessed in the following diagram.

基本电路图

在上面的部分中，我们学会了如何使用5mm LED连接低功率的光电路，在这里我们看到如何使用4瓦功率LED进行相同的操作。杰克先生提出了这个想法。

技术规格

你好赃物,

During my exploration of LED lighting and the various circuits employed I would like to post some of my recent finding. Acknowledgements to LED Magazine and Steve Roberts. I've attached several pictures of my recent build,.....28 - 3watt leds, 7 leds, in series per row and 4 row in parallel. I'm using a 24v-32v, 4amp power supply.

These lights were purchased as emitters and the bases had to made and heat sinks applied to each emitter. The leds were mounted to aluminum channel.

Since the completion of the circuit, I've experienced various heating problems and it was continuing to be difficult to balance the circuit, to run cool, stable, and steady electronic output. I decided to look deeper into this and leds in general and here is what I've found.

即使LED全部来自相同的生产批次和依次制造，单个LED的Foward电压（VF）仍然具有公差±20％。

公差这一高度意味着每个LED的总正向电压可能非常不同，因此当前的不匹配可能非常重要。

考虑，如果我们有5个串联的LED，正向电压为4V，则为（4V）（5）= 20V。错误的！！！

Given the tolerance above, the forward voltage is really, 16v to 24v, that an 8v spread. How are you going to design a circuit that requires you to place things in BALANCE if the tolerances are that hight? This is one of the reasons that things go array. There are many others!!!

For a newcomer or a new hobbyist wiring LED lights could look complex with many hidden intricacies, actually it's not.

接线LED

仅需根据规则就可以完成正确的结果。

指杰克先生发送的上述图像，我们可以看到LED字符串未正确接线，这就是为什么设计给出错误且不稳定的响应的原因。

You should never wire LEDs having different V/I specs in series.

当需要实现串联连接时，您应始终将具有相同规格的LED分组在一起。

However if the requirement is in a mix and match manner as in the above images, yet still the same color LEDs must be connected in series and if necessary in parallel with their individual series resistors.

High watt LEDs will emit heat, therefore assembling these devices over a heatsink is imperative and to avoid a thermal runaway we can incorporate acurrent regulator, that's all right, no issues with these parameters.

But said that the LEDs must be wired up as instructed in the above paragraphs, only then you would be able to acquire an efficient response from the system.

And suppose you have a power supply which is rated to supply a lower voltage but higher current in that case you could simply hook up all the LEDs singly in parallel with each LED equipped with its own limiting resistor, a well calculated one.

使用功率LED计算生长光电路的LED

我已经在以前的一篇文章中讨论过，您可以阅读这里

因此，在上图中应如下图所示，将LED接线的正确方法应如下图所示。

现在，相应字符串的所有正和负末端都需要与电源（+）/（ - ）终端集成

如果您有任何疑问或疑问，请随时在下面的评论框中发布它们。

I think I completely missed something in the above design.

Since the current specs of all the LEDs are same, voltage specs can be ignored,不同的颜色LED可能在相同的字符串中连接。

因此，让我们再次正确分析设计。

左的第一个字符串具有4个红色LED和3个蓝色LED，电源为24V，因此该字符串的当前限制电阻可以计算如下：

R = supply minus total LED fwd. voltage divided by LED current

= 24 - (4x2)+(3x3.2) divided by 0.6 (600mA)

= 10.66欧姆

wattage =(4x2) + (3x3.2) x 0.6 = 10,56 watts

您也可以以上述方式计算其他字符串的电阻。

如下所述，可以构建上述设置的当前控制。
