水草情迷

hi all,

我是無意中發現的...
http://www.ledgrowlights.com/index.htm



他們的Links中有用LED做實驗種植陸上植物, 並作出分析及結論, 也嘗試用不同的紅, 藍, 白光作出比較. (有比較結果的圖片的)

我記得最近睇"日本風情畫", 其中有一集介紹用LED種植蔬菜, 效果理想, 並且已經推出市場售買.

如果草缸真的可以應用, 就一流了 !!
- 低溫
- 長壽
- 穿透力強
- 慳電tim...唔洗比老婆鬧 hoho

真係好想diy一個比個10"缸玩, 不過我想知道DIY LED可不可以自己隨時換bulb呢? 我只依稀記得以前用電子板焊接過一個, 每次換LED, 可否不用焊接呀? 謝謝!

我都依稀記得，在長沙灣道近政府合署對面(唔知有無記錯)，
有間LED專門店，有各種各色超光號型，
或者有啲已經焊好嘅組合賣，唔使自已DIY，
有時間去開鴨記或黃金，順便行過去睇吓，
我都希望你成功，比草友多樣野玩吓，
努力!!!!!!!!!!!!!!!!!!!!!!!!!!!!

hi yeungwt,

THX a lot!
未知你能否遲些方便確定到地址, 再另行告之. 因為我絕少行深水步的.

我係新填地街附近就見過有一間LED專門店.

不過如果每次換LED都要焊接的話, 我就有d怕煩 =P

冇錯..係正政府合署對面(長沙灣道近九江街)有間地舖有好多款LED產品賣. 鴨記賣d LED成本都唔平 (超光紅藍1蚊粒, 白色甚至要2.5-5蚊粒), 加上係鴨記d LED好多都冇spec, 唔知佢放咩 wavelength 0既光, 好難可以做到好似個外國site咁 pro.

果個外國 website真係好好睇, many thanks.

Very interest in this. Any recommendation on how many LED requires? Any calculation/principle on the relationship between volume of water vs no. of LED?

hi kkm,

u are welcome and thank a lot...i will check it out later

hi mitac,
have read this page?
http://www.ledgrowlights.com/FAQs.htm#howmany
but i dunno if it can apply into our aquatic grass tank. let's try together la.... hehe... remember to report us the result wor...=P

and one hint from another other page ( http://www.ledgrowlights.com/ADVANTAGES.htm) said that
"Plants can use nearly all of the light emitted from LED lamps. Only a small part (~10%) of the light generated by metal halide lamps is useful for plant growth."

and there are so many spec on internet (talk about luminous and view angle)....i think i can help.

HI ALL,

先謝過yeungwt, kkm. 昨天已去過了那間店鋪, 自覺很有用 (特別係佢地DIY的那座LED燈...他們也願意幫人DIY, 我問有關接駁問題, 他們也樂意回答, 而且也聽過LED種植.
佢地的website都幾有趣, 特別係"Garden Light Series", 更有簡單的spec. download, 相信大家都會有興趣的. 我特意問他們拿一份有關紅, 藍, 白的spec (他們沒有黑光LED), 他們說會一兩天內e-mail比我, 如果真的話, 再分享給大家研究.

Ｗｉｎｚ兄，個ｓｉｔｅ好正呀，如果唔係半年前先改了用Ｔ５ＨＯ我一定用佢來試試，不過我最擔心係穿透力不足．有無其他草友試呀．

Winz, 有spec就唔同啦 !

前兩日我都去左鴨記買左幾粒LED(紅同藍)玩下, $1/粒, 紅色果粒光到盲, 藍色就渣d. 但發覺唔同顏色LED需要唔同大小0既電流, 因為如果張藍同紅接駁埋一齊, 藍色係冇光, 後來搵到個唔錯0既website去計唔同顏色LED0既電流同電阻配合, 呢個site對d好似我咁0既初學者黎講十分有用

白光的LED會唔會contain水草要的wavelenght?
or need to buy red and blue ?

hi GWU,

SUPER 兄以前用過LED造夜光, 看看幫唔幫到你

或者再有唔明再問SUPER兄la...

hi kkm,
aiya...唔可以mix埋一齊玩? 我見 http://www.csd.net/~cgadd/aqua/art_nightlight.htm 可以紅藍一齊玩... 你買的LED係唔係超光LED? 我在你介紹的那間鋪, 職員特意demo 超光藍色LED, 我都發覺都光到盲wor...

cool~ 你找的calculator重易明過我的那個, THX:

我還有一個home built LED的website (但我因最近好頭痛還未看), 或者先分享給你:

hi poontommy,
看看能幫到你嗎?

hi all,

the above attactment is SOME of blue, red and white LEDs' spec from Top Century Company....
they have a lot of different view angle* of LEDs... from 1x to 180 degree. however, i asked them for 17.5 degree only.

* view angle ↑ ---> $ ↑ ---> may not in the same series model of LED ---> decentralized Luminous Intensity

they also have different Luminous Intensity LEDs, but i ask for max., med. and min. only.....

tell me....if u all have any problem(s).

enjoy it!

ps.
- THX mr.super help me to upload the file.
- the shopkeeper told me....someone bought their LED for the grass tank be4 a month.... who who who?? hehe....naughty!! =P ... would u mind share ur experience to us if u are the secret man? thx

poontommy: 白色係包含所有色譜, 道理上會有植物需要的wavelength, 不過白色LED真係好貴

個spec好詳細, 種類都好多, 唔該哂, 最衰無價錢

Ｗｉｎｚ兄，我見佢地個ｓｉｔｅ有Ｄ現成嘅ＬＥＤ裝在普通的石英謄座，用ＤＣ１２Ｖ的，唔知在店舖內你有無見過呀同幾多錢，如果有，我想ＤＩＹ都易Ｄ媽！起碼Ｄ fitting用番普通的石英燈就得啦.

Hi, All DIY fans
用Led做植物燈，這個話題以前提出過，但是有些綱友還是摸索不着要點，小弟提出數點，希望各位DIY成功﹗
1, 根據 ledgrowlight 的資料:每平方呎要求10~20 watt 的 紅色leds 1~2 watt 的 藍色 led, 給普通植物，水草嗎，要加多10%.
(每粒 led 功率大約是0.1~0.5 watt. 不斷提高﹗)
2,白色的 led 應該是理想的目標 led 了。色温有6500度 K。
3, 角度窄的，穿透力强一些。
p.s. 黑燈 led 己經有得賣了，鴨記不是有些匙扣燈用來 check 銀紙的嗎﹖
