简介:为您的家庭照片工作室构建一个口袋RGB LED灯

激励我开始这个项目的活动是我女儿要求我的帮助制作一些特殊照片的时间。她不是专业的摄影师,但她对这个艺术形式非常热衷,并期待着一些有趣的摄影。

因此,我们对LED的兴趣混合了她对拍照的倾向,并创造了您即将描述的项目。

已有亚马逊上可用的彩色LED灯(Pocket RGB LED灯)的设备已有,例如:

to enumerate just a few.

在我看来使用这种设备的最有用的东西是您可以缓慢地或以速度慢慢改变颜色。您也可以控制色调和颜色的饱和度,因此您可以使用一系列符号来选择。每个设备都有几个我喜欢的选项,其他设备有不同的选项是有用的,但我没有找到我想要的所有选项中的一个设备。我以为我能做的就是在微控制器上安装一个软件,它会指示LED,以便我可以实现我想要的照明效果。通过这种方式,我可以尝试并找出相当速度的颜色适合我的主题。

You have to keep in mind that nothing compares to doing something with your own hands, so that it will work exactly the way you want it to. Am I right? Thus, I can create this device exactly as I want. The construction is not complicated at all, the electronics are cheap (as usual for me ) the only requirement could be the possession of a 3D printer, although this is not really necessary because there are companies that can print the components of the led panel. The effects this tool gives create an amazing look to pictures, as you will see in the last step of the project. And it can be used not only for photos, but also for video filming, so that you can capture the way the lights are changing.

这可以在本技术中完全举例说明视频例如,互联网上还有许多其他教程描述了使用这些Pocket LED灯的方式,这些教程适用于我们的设备,因为它以与此类型的其他设备相同的方式工作,它提供了许多选项(如果不是更多)。

所以让我们开始!

第1步:材料,组件

对于我使用的该设备的构造:

  • 口袋RGB LED灯体和LED支撑(2个变体,施工步骤更多) - 印在3D打印机上,这是STL文件的链接tinkercad.;
  • A piece (158x140 mm) of transparent plexiglass (maybe also transparent white) as a screen;
  • Window privacy foil (frosted white - gives the impression of a smooth, textured light), ;
  • 一条带68 WS2812 LED(60 LED / M)的LED条带;
  • An ESP-01 module;
  • An RGB LED controller for ESP-01;
  • 5.5x2.5mm直流母插塞带电缆;
  • 5V power supply with 5.5x2.5mm DC Male Plug

我用PLA材料的3D打印用“铝制”颜色,看起来壳体由金属制成:) LED支架被迫进入其位置,因此没有必要粘合它。在盒子的两侧,我提供了一些通风的孔,因为,从我的经验,在高亮度下,LED获得有点热,PLA对高热量没有很强。然而,应避免使用LED面板以最大亮度,因为它还缩短了LED的寿命。

我还为此设备设计了两个3D可打印配件,其基本上用于更好地集中光通量。我还没有尝试过他们,也许是在未来,但我会为您提供STL文件,也是如此tinkercad.

Also here you can download an STL file for a nut that can be inserted into the slot in the housing of the device with which you can attach the pocket RGB LED Light to a tripod. The nut is not my project but you can find it on Tinkercadhere

If you want, the plexiglass board for the screen can be transparent because the white foil filters and lowers the intensity of the LEDs light a little.

The electronic components are very cheap (especially if ordered from China )

  • LED 3.3美元
  • ESP-01 module $2.2
  • RGB LED controller module $0.9
  • Plug with cable $ 0.25

The 5v power supply however must be of good quality and relatively high current. For 68 LEDs at maximum white brightness the required current would be about 4A (68 * 60mA). In order to be in the safety margin and not to overload the power supply, it should be able to output about 6A. The 5v/6A power supply can cost about $10- $12 so it would be about the most expensive component. But it is necessary. If we do not provide the required current for the diodes, in addition to the fact that they will not illuminate at maximum brightness, they will also have a very annoying flickering. To this cost would be added the price of the 3D printing (which is only the price of the material if I use my own 3D printer) and plexiglass costs a few tens of cents. In the end, the cost would be about $15, much cheaper than any of the pocket RGB LED lights on the market today.

Step 2: Software

However, all this construction receives added value by using quality software. And because the ESP8266 microcontrollers from the ESP-01 boards have gained a huge popularity, I had a great variety of programs to choose from. At a first search I found the following solutions:

迄今为止,我最喜欢的是我最喜欢的那个,它提供了我想要的一切都是一个小照明面板的一切!它也是非常易于安装的,Web界面是美观实用的,“WLED”的事实也为Android提供了客户,iOS是一个大加上。

我不会坚持配置和使用WLED,因为有一系列HOWTOS和视频,还有一些您可以找到的文章WLED WIKI.

但是,要从WLED配置开始,我强烈推荐下面的视频

第3步:建筑

After printing the case and the LED support, I proceeded to the actual mounting of the LEDs on the support. During the design I had to choose between three LED mounting possibilities at the same size of the housing:

- 具有48个LED的变体

- A variant with 83 LEDs

- 具有68个LED的变体

我使用了最后一个版本(既不是太少也不太多的LED)但是tinkercad.您还可以找到第二个版本的LED支持。支撑件中的孔不仅提供用于隐藏LED条带之间的连接线,而且还提供了帮助将它们定位在支撑件上。

安装并粘合LED条带的碎片后,我将接触电缆焊接到RGB LED控制器模块后,我通过壳体中的孔通过孔焊接到相同的LED控制器模块中的5V电源线。我认为,没有必要是电子计划,上面的图像为自己说话。下一步是将固件加载到ESP-01模块中,如下所示:

  • 我下载了ESPHome-Flasher, currently version 1.3.0;
  • 我从中下载了固件WLED GITHUB.即wled_0.10.0_esp8266_1m_full.bin;
  • 我将ESP模块附加到程序员(用于上传程序,我在图片中使用了程序员,我也使用它在我的其他项目中,例如我的桌面戒指时钟);
  • I inserted the programmer (with the ESP module attached and the button pressed) into a USB port (then I released the button, the ESP entered programming mode);
  • 我开始ephome-flasher,我选择了程序员的COM端口,先前下载的固件和我开始写作
  • 写入完成后,我关闭了Esphome-Flasher,我从USB端口删除了程序员。

最后我将ESP模块放在RGB LED控制器中,我安装了框中的所有内容并附加了有机玻璃。

With this setup I measured 140 lux at 1m distance at full white (with an app on my phone, I don't have a dedicated lux meter ). It may seem too small of a value but don't forget that WS2812 LEDs were not invented for this purpose. In any case, as you will see, we can still use them as an accessory in an amateur photo lab.

就这样。

Step 4: The Pocket RGB LED Light in Action

所以WLED固件安装并运行良好。

我看了一些关于它使用的视频,我红色一些Howtos,我继续拍一些照片和一些短视频。

我附上有些照片,我的女儿用她的尼康D3300 DSLR。

Great thanks to our cat Sophie for being such a great model for us even if it was a little bit hard to work with her

在幕后,潮汐......

在制作照片中,我们为所有68个LED和两种颜色使用一种颜色,为LED的每一半。
对于那种视频,用手机拍摄,我尝试了一个红色和蓝色的“走路效果”(我将LED灯移动到了主题上),以及一些WLED效果:“彩虹”对旋转娃娃的影响和“闪耀”的影响对我的影响桌面戒指时钟。您可以观看下面的合并视频。

It might not be the best quality but as I told you, my daughter and I are just enthusiastic amateurs

但没有参与照片制作的照片!

第5步:结论

即使设备的光强度相当低,我已经构建的口袋RGB LED灯也非常可用。为了增加光强度的值,您可以构建和使用更多这样的设备,您可以使用更多LED甚至更强大的RGB LED。

I also thought that two WS2812 LED arrays could be used with 64 LEDs each, as in the photo below,

该装置可以较小,它将具有更多的LED(128)和更高的光强度。

谢谢你到目前为止的阅读,我希望你喜欢我的文章,我已经为你的问题和观察常见了

    如果您正在谈论大约2.5x4英寸的蓝色,用单个COB LED,我已经看到了一些从修改它们的人的YouTube视频。我很确定有一个用Lipo取代AAA细胞,所以它可能会节省有不合理的电池终端。

    为了避免损坏,这是HFT有优惠券的几个月之一,以便在碱土中获得大折扣。我有几个手电筒,其中大多数我被“免费购买”优惠券,所以我会带着耐用的手电站,耐用的一部分。

    看起来很棒!
    我认为任何人都做这个,你可能想要的to get RGBW LEDs, that's LEDs that also have a white LED built in. I've made a few lights with just RGB LEDs and while the colors look good, white light never seems right. Turns out the LEDs are so narrow in their color that they can be weird for white light, but throwing in a few white LEDs makes it much closer to full-spectrum light.

    很好地完成了一件伟大的成品。为一个有助于促进其创造力的人创造一些东西是一种美妙的感觉。当您将其与市售版本进行比较时,它很容易批评您自己的创作,(RE:亮度),但只记得他们是在R&D团队的帮助下设计和制作的,并且可以访问您的平均发烧友无法使用的技术。你应该为你的成就感到自豪..
