3 Quick Start

快速上手视频:http://v.youku.com/v_show/id_XMTY1MTMzMjA0NA==.html


Maike-wifi-bulb-2955-all.jpg

  • 灯通电,等待 8 s左右
  • 灯在红色渐变,表示灯在等待配网
  • 如果不在红色渐变,请开关三次(开 – 灯亮 – 关,重复三次),可进入红色渐变等待配网状态
  • 手机连接 WiFi 路由,微信扫描右侧二维码,点击 ”配置设备上网“
  • 按提示输入 WiFi 密码,点 “连接”,等待配网完成(注意,设备不支持 5G WiFi,只支持 2.4G;另外企业级安全认证也不支持)
  • WiFi 配置完成后,微信自动进入局域网发现设备模式,其会列出设备列表
  • 点击第一个设备,进入页面,在页面最下面会有 “绑定设备” 按钮 (如果已经绑定过改设备,最下面的按钮为“进入公众号”),点击按钮,完成设备绑定
  • 完成后,点“进入公众号”,在公众号菜单的 “智能设备”,即可列出你绑定的所有设备,点一个设备,即可进入设备控制页

其他说明:
  • 其他人需要控制设备,需要先连接到同样的路由器,在设备通电的情形下,扫描同样的二维码,点“设备已联网,跳过此步”,直接“发现”、“绑定设备” 即可在公众号菜单“智能设备里控制
  • 灯泡要迁移到其他的路由,可开关三次,扫描二维码配一下网络即可,无需再绑定
  • 灯泡从家移到公司,找不到原来的路由会自动进入等待配网状态(红色渐变),扫描二维码配一下网络即可
  • 开关 6次(开 – 灯亮 – 关,重复 6次),可恢复出厂设置



4 Open API

Afer you guys 'Link Device' in WeChat, Enter Official Account:


  • click "Devices" to list your binding devices
  • select your OpenLight in the list, enter control page, click upright corner, then Copy URL
  • paste the URL into web browser (Chrome or Safari) to access the control page in browser
  • check the source code of the page to get the following variables:


var devid = YOUR_DEVICE_ID;
var mqtt_uname = xxxxxxxx;
var mqtt_pass = TTTTTTTTTTTTTTTT;                           < ---- 3600s life time
var mqtt_server = xxx.xxx.xxx.xxx;
var mqtt_port = xxx;



4.1 node.js

Prepare the node.js:

# download the node-v6.9.1-xxx.tgz from http://nodejs.org
$ tar xf node-v6.9.1-*.tar.xz
$ sudo cp -a node-v6.9.1*/*  /usr/local/
$ sudo npm install -g MQTTClient
$ sudo npm install -g request



4.1.1 Turn Off

Using the node.js to switch off the OpenLigh:

$ cat light-off.js
#! /usr/bin/env node

var opt = {
    username: "YOUR_mqtt_uname",
    password: ""
};
var http_req = require('/usr/local/lib/node_modules/request');
http_req.post(
	'http://api.noduino.org/user/token',
	{ json: {user_id: opt.username} },
	function (error, response, body) {
		if (!error && response.statusCode == 200) {
			console.log(body);

			opt.password = body.user_token;

			var MQTTClient = require('MQTTClient').Client;
			var client = new MQTTClient('mqtt.noduino.org', 1883, opt);
			client.connect(function () {
				console.log("connect ok!");

				var pubopt = {
					qos_level:  2
				};

				var state = {
					on: 0          <---- off
				};
				var data = '{"m":"set", "d":{' + '"s":' + state.on + '}}';
				client.publish('app2dev/YOUR_DEVICE_ID', data, pubopt, function (message_id) {
					console.log("public ok! message_id = " + message_id);
					process.exit(0);
				});
			});
		} else {

			process.exit(1);
		}
	}
);

$ ./light-off.js



4.1.2 Turn On

Turn on the OpenLight:

$ cat light-on.js
#! /usr/bin/env node

var opt = {
    username: "YOUR_mqtt_uname",
    password: ""
};
var http_req = require('/usr/local/lib/node_modules/request');
http_req.post(
	'http://api.noduino.org/user/token',
	{ json: {user_id: opt.username, app_id:"mj2030064278", app_key:"0077d4829f52b1b2d668f8a82c5f5ded"} },

4.1.3 Setup Color

Change the color of the OpenLight:

$ cat light-color.js
#! /usr/bin/env node

5 极客定制

5.1 编译固件

获取 noduino-sdk:

$ git clone --recursive git://github.com/noduino/noduino-sdk.git noduino-sdk


生成 toolchain (you need Python 2.7):

$ cd noduino-sdk/toolchain
$ ./gen.py

编译:

$ cd ../sketch/open-light
$ make



5.2 烧写固件

5.2.1 Serial

Prepare a USB2UART board, something like FT232RL or CP2102/CP2104:

Ft232.jpg


Upload firmware throught serial for OpenLight Bulb:

Openlight-bulb-upload-serial-900.jpg]


Upload firmware throught serial for OpenLight Controller:

5pin.jpg


  • USB2UART_GND ------> SmartNode_GPIO0 / Bulb_GPIO0
  • USB2UAR_GND -----> SmartNode_GND / Bulb_GND
  • USB2UAR_RXD -----> SmartNode_TX / Bulb_TX
  • USB2UAR_TXD -----> SmartNode_RX / Bulb_TX


Connect USB2UAR_VCC3.3 -----> SmartNode_VCC / Bulb_3V3 at last

ESP8285 will be enter upload mode, we can upload the compiled firmware through serial using following commands in Linux:

$ cd /path/to/noduino-sdk/sketch/open-light
$ make produce ESPPORT=/dev/ttyUSB1


In windows:

$ make produce ESPPORT=COM7

COM7 is your USB2UART device


In MAC OS, maybe it's:

$ make produce ESPPORT=/dev/cu.SLAB_USBtoUART

/dev/cu.SLAB_USBtoUART is your USB2UART device

6 硬件原理

6.1 Cree LED

XLamp XHP70.2:

  • 7 x 7 mm
  • 6V, 12V
  • 4800, 2400 mA
  • 29 W
  • 125 °
  • 3408 Lum @4000K 70CRI


6.2 LED 灯珠

LED 灯珠 (5730) 单颗特性为:

  • 尺寸 5.7 x 3.0 mm
  • 最大电流 150mA (0.5W)
  • VF 为 3.0 - 3.4V (Red LED为 2.0 - 2.2V)
  • 亮度 50 - 55 lm


LED 灯珠其实就是一个二极管,只要有一个正向导通电压 (VF) 就能发光,一般为 2 - 3.5V,低于此电压灯珠不能发光,高于此电压,灯珠会烧坏。


LED 伏安特性:

LED-V-I.jpg

  • 高于开启电压,LED 发光, 开启电压对不同 LED 其值不同,GaAs 为 1V,红色 GaAsP 为 1.2V,GaP 为 1.8V,GaN 为 2.5V
  • 随着电压升高,电流指数级增大。。。
  • 温度越高,开启电压越低,上述伏安曲线图,整体向左平移。。。


>> 控制灯珠亮度的,是电流大小,因此调光灯实际调得是电流的大小。电流超过额定电流,会加速灯珠老化,缩短灯珠寿命:


OpenLight 16W 3200K 白光吸顶盘实测:

  • RGBW = 255, 四路电压 11.50V; 11.5V/4 = 2.875V
  • RGBW = 186, 四路电压 11.08V
  • RGBW = 125, 四路电压 10.50V
  • RGBW = 051, 四路电压 09.86V
  • RGBW = 005, 四路电压 09.43V; 9.43V/4 = 2.35V



6.3 高显 LED 灯珠

  • 蓝光 LED + YAG 荧光粉的二基色白光 LED 的显色指数一直徘徊在60—80之间,其主要原因是在YAG光谱中,缺少红光部分的光谱,使获得的白光LED的一般显色指数偏低。

提高传统蓝光 LED + YAG 荧光粉的二基色白光 LED 显色指数的方法是增加其白光光谱中的红光辐射成分,比如加入一个红光 LED,通过调整电流来调整白光和红光的亮度,然后测量显色指数等色度学参数,获得白光和红光的配比。这种方式的缺点是耗时繁琐。



6.4 FP7102

  • 输入电压:3.6V ~ 28V
  • 输出电压:2V ~ 25V
  • 输出电流:2A
  • 最大 50W = 25V x 2A,生猛!
  • 效率:93%
  • 工作频率:320KHZ
  • 内置MOS为低内阻 PMOS
  • 4mA 超低工作电流
  • 内置:过温,过流,软起动保护


FP7102.png


FP7102 datasheet


  • R2 为限流电阻,Imax = 0.25V / R2
  • 芯片最大输出 2A,因此 R2 一定要大于 0.13Ω = 0.25V/ 2A
  • 比如 12 颗 0.5W 5730 白光 LED,极限 0.15A x12 = 1.8A, R2 = 0.25V/1.8A = 0.139Ω
  • FP7102 的输出电压随所接之 LED 拓扑而变化,最多支持 28V/3V = 9 颗串


6.5 MY9291

台湾明阳 4 通道恒流 LED 驱动芯片,可控制 R, G, B, W 四路 LED 灯珠


特性:
  • 3.3 - 5V 电源电压范围(±10%)
  • 每个通道 5 - 350 mA 恒流输出范围
  • 可承受最大输出电压 24V,支持多颗 LED 串联
  • 外接器件少,仅需四个外接电组来设定四組恆流电流


框图:

MY9291.app.jpg

电源为恒压源,可以多片级联,MCU 的控制线就两个:DI 和 DCK


电源电压与灯珠串并联确定:
  • 12V 电源的情形,如选用 VF 为 3V 左右的 LED 灯珠,则需要 4 颗串联,这样每颗灯珠分到电压为 3V 左右;2V 左右的灯珠,则需要 6 颗串联
  • 24V 电源,则 3V 灯珠 8 颗串联,2V 灯珠 12 颗串联
  • 6V 电源,则 3V 灯珠 2 颗串联,2V 灯珠 3 颗串联


输出限流

MY9291 单路最大输出 350mA,为节约灯珠寿命,可限制通过灯珠的最大电流以节约灯珠寿命

最大输出电流限制:

 R = 0.38V / Iout

满输出 350mA,则每路的限流电阻都得选为:1R,1/4 W 够用


  • OpenLight 球泡 RGBW 灯,R/G/B 选用电阻 4R7,限流为 81mA 左右,W 用两个 4R7 并联 2.35R 左右,限流为 162mA 左右。这样基本限制经过每颗 5730 (0.5W) 灯珠的电流为 80mA 左右,以延迟灯珠老化。这样整体功率被限制在 5W,如要增加亮度,可将这 5 个 4R7 电阻替换为 3R0,可将输出功率增加到 7W
  • OpenLight 球泡 WWWW 灯,选用电阻 2R7,限流为 141mA
  • OpenLight 控制器,1R2 限流为 317mA,1R3 则限流为 269mA,可酌情选用


6.6 其他

  • MY9231 3 通道恒流 LED 驱动芯片
  • MY9221 12 通道恒流 LED 驱动芯片



6.7 可选方案

OpenLight 铝基板上,LED 灯珠默认布局为:

  • Red LED 6 颗串联,正极接 12V,负极接控制板 R (MY9291 之 OUTA)
  • Green LED 4 颗串联,正极接 12V,负极接控制板 G (MY9291 之 OUTB)
  • Blue LED 4 颗串联,正极接 12V,负极接控制板 B (MY9291 之 OUTC)
  • White LED x8 (4 颗串联为一组, 2 组并联,正极接 12V,负极接控制板 W (MY9291 之 OUTC))
