The Development of Flameproof LED Luminaries

[[abstract]]根據工安全衛生設施規則規定，使用於易燃易爆之作業場所的電氣機械裝置、設備，應具有適合之防爆性能構造，且必須通過檢定測試。燈具為每個工廠皆必備之電氣設備，若是防爆功能不足，可能成為潛在引火源，造成工廠龐大的損失。 我國防爆燈具的市場十分龐大，每年進口金額有數億元之多，但國內製造商的出口值卻僅有數百萬元。歸咎其原因，乃與國內推行防爆認證制度起步較晚，防爆性能之有效性令人存疑，因而使得事業單位選擇購買通過國外認證之防爆商品，造成國內市場逐漸萎縮。 近年來，環保議題逐漸被各國所重視，節能減碳也為企業開發產品的目標。在照明方面，LED擁有省電、體積小、冷光源、壽命長…等許多傳統照明設備所沒有的優點，已逐漸成為未來照明的主流。 因此，本研究利用LED的優點，將其設計成具耐壓防爆性能(構造)之照明燈具，並以通過國內耐壓防爆檢定測試為開發目標。 所開發之燈具可承受0 41MPa的內部爆炸壓力，器殼表面則可承受0 7J的外力的衝擊，表示器殼具有足夠的強度，但由於螺紋的切削加工精密度不足，因此無法阻止燈具內部爆炸產生之火焰逸出至外部。本研究同時提出改善方向與策略。[[abstract]]The market of flameproof lamps is estimated more than hundreds million dollars in Taiwan but only 10%is occupied by the domestic manufacturers The main reason is that not many manufacturers qualified the type examination which distract the buyers to consume from other countries The purpose of this research is to take LED’s advantages to renovate a new flameproof LED lamps achieve the type examination According to the Laborer Safety Sanitation Facilities Regulaton the machines and equipments used in flammable and explosive environment should build up the explosion-proof electrical structure and should be qualified type examination The lamps are the essential equipments in manufactures if the concerned safety of lamps were neglected they might cost the unexpected lost Compare to the traditional lamps LED lamps get more advantages such as practise economy on electricity longer life and mini-size Therefore LED will be the trend which applied the the luminaries business The experiments show that the internal structure of the lamp can endure 0 41Mpa explosion pressure and the surface can endure 0 71J concussion However the crack on the lathe of thread caused the flame lick through the surface of the lamps This research will discuss the strategies to improve and renovate the LED lamp
