各位師兄好.
小弟新手一名, 因工作需要, 要影衫做 product 相, 所以買了兩部影樓燈, 放喺寫字樓影相, 2009 年五月買, 呢排有個問題好恐佈, 就係
唔知點解, 影影下 (大概影咗廿零分鐘), 唔知邊盞燈, 會突然間好大聲咁 "呯" 一聲.
好大聲, 好似爆炸咁聲, 嚇到我差啲連部機都跌埋

但又無燒, 又無味, 隔日我又開返嚟影, 又影到喎...但係耐唔耐佢又爆一鑊

我拎部燈去鋪頭請佢幫我 check check, 佢話無事, 當堂插電制試, 又 ok 喎...

有冇師兄可以指教一下, 究竟係咪盞燈有問題定係咩原因? 家陣我一路影相, 一路都提心吊膽~~~

thx.

Maybe we try to start from 2 ways:

1. overheat; and
2. electronics parts - capacitors.

What is your habbit of taking photos?
Do you like to turn the flash to max. output?
Do you like to taking shoots non-stop?

Are the flash need to release once before turn-off?
Any un-ususal sound when charging?

Hi lokism3,

謝謝你的回覆!

--- What is your habbit of taking photos?
通常我影衣服, 每件衫要影四個不同角度, 每個角度會影 3-4 張以便選擇.
每一次我會影大約 8-9 件衫, 約莫係 2 - 2.5 個小時

--- Do you like to turn the flash to max. output?
冇呀. 主燈我調較至 1/2; 輔助燈我調較至 1/8 - 1/4

--- Do you like to taking shoots non-stop?
如下所述, 每次連續影 2 - 2.5 個小時
(但自從發生 "爆炸" 事件後, 每次我影一個鐘, 就會熄燈抖返約莫 15 分鐘)

--- Are the flash need to release once before turn-off?
有呀, 每次熄燈前, 我都襟多次 "text" 放電的

--- Any un-ususal sound when charging?
又冇呀...都 ok 正常

希望各位能幫忙一下, 起碼我就算要買過盞燈, 以後都能避免同類事項出現啦, thx.

It seems that the flashs are alright at the moment,
and you're not using them normal.

The problem is not from overheat... sorry, no idea.
Maybe, it is just an accident...

Please let me suggest a few points about flash usages:
1. keep clear around the flash: put nothing too close, expecially the flash & modeling tubes inside the reflector;
2. avoid to flash severval times within a short period; and
3. abnormal noise during charging is signal of the electronics inside getting old, and its time to change the whole unit.

影樓閃光燈不同機頂燈, 是可以受大量的拍攝工作.

你的問題, 有機會是閃光燈的電容接觸位鬆了, 也可能是閃光膽鬆了, 和閃光燈接觸不好, 強大電流流通時和空氣發生火花發出聲
