Since ordinary lighting fixtures inevitably generate electric sparks or form hot surfaces during operation, once they meet the explosive gas mixture at the production or rescue site, it will lead to an explosion accident and endanger life.
The electrical parts of ordinary lamps will be exposed more or less. Due to electrical faults or aging lines, once they come into contact with explosive gases and combustible dust, they may become BOOM!
The explosion-proof lamp can prevent the arc, spark and high temperature that may be generated inside the lamp from igniting the combustible gas and dust in the surrounding environment, so as to meet the explosion-proof requirements.
LED explosion-proof light is a kind of explosion-proof light. Its principle is the same as that of explosion-proof light, except that the light source is LED light source, which refers to various specific measures taken to prevent the ignition of surrounding explosive mixtures such as explosive gas environment, explosive dust environment, gas gas, etc. Measure light fixtures
LED explosion-proof lamps are currently the most energy-efficient explosion-proof lamps, suitable for petrochemical, chemical, pharmaceutical and other special processing and manufacturing industries, as well as more special warehouses, workshops and other indoor and outdoor places that require flood lighting.
According to the “Standards for Determining Hidden Hazards of Major Production Safety Accidents in the Industry and Trade Industry” (2017 Edition), the following situations can be determined as major hidden dangers.
In the industrial fields with dust explosion hazard, explosion-proof electrical equipment and facilities are not used in Zone 20 of the dust explosion hazard place.
In the metallurgical industry, gas cabinets are built in densely populated areas, not far from important facilities such as large buildings, warehouses, communication and transportation hubs; auxiliary equipment and facilities are not equipped with explosion-proof equipment according to fire and explosion-proof requirements; no lightning protection device is installed on the top of the cabinet.
The machinery industry and light industry have not set up explosion-proof electrical equipment and facilities in accordance with the specifications.

Kwa kuwa taa za kawaida hutokeza umeme au kuunda nyuso moto wakati wa kazi, mara tu zinakutana na mchanganyiko wa gesi ya kulipuka kwenye eneo la uzalishaji au uokoaji, itasababisha ajali ya mlipuko na kuhatarisha maisha. Sehemu za umeme za taa za kawaida zitakuwa wazi zaidi au chini. Kwa sababu ya kasoro za umeme au nyaya za uzee, zinapogusa gesi zenye mlipuko na vumbi linaloweza kuwaka, zinaweza kuwa BOOM! Mwangaza wa mlipuko wa taa inaweza kuzuia arc, moto na joto la juu ambalo linaweza kuzalishwa ndani ya taa kutoka kwa kuwasha gesi inayoweza kuwaka na vumbi katika mazingira ya karibu, ili kukidhi mahitaji ya mlipuko. LED explosion-proof mwanga ni aina ya mlipuko-upinzani mwanga. "Kifungu cha msingi ni sawa na ile ya ""mwanga wa mlipuko,"" isipokuwa kwamba chanzo cha mwanga ni chanzo cha mwanga cha LED, ambacho kinarejelea hatua mbalimbali maalum zilizochukuliwa ili kuzuia moto wa mchanganyiko wa mlipuko wa karibu kama vile mazingira ya gesi ya mlipuko, mazingira ya vumbi la mlipuko, gesi ya gesi, na kadhalika." Taa za LED za kuzuia mlipuko ni taa za kuzuia mlipuko zenye ufanisi zaidi wa nishati, zinazofaa kwa viwanda vya petrochemical, kemikali, dawa na viwanda vingine vya usindikaji na utengenezaji maalum, pamoja na maghala maalum zaidi, warsha na maeneo mengine ya ndani na nje ambayo yanahitaji taa ya mafuriko. "Kwa mujibu wa ""Mipaka ya kuamua hatari zilizofichwa za ajali kubwa za usalama wa uzalishaji katika viwanda na biashara"" (Toleo la 2017), hali zifuatazo zinaweza kuamuliwa kama hatari kubwa zilizofichwa." Katika maeneo ya viwanda na hatari ya mlipuko wa vumbi, vifaa vya umeme vya mlipuko na vifaa havitumiki katika eneo la 20 la hatari ya mlipuko wa vumbi. Katika viwanda vya chuma, makabati ya gesi hujengwa katika maeneo yenye watu wengi, karibu na vifaa muhimu kama vile majengo makubwa, maghala, mawasiliano na vituo vya usafirishaji; vifaa vya kusaidia na vifaa havina vifaa vya kuzuia mlipuko kulingana na mahitaji ya moto na mlipuko; hakuna kifaa cha ulinzi wa umeme kilichowekwa juu ya kabati. Viwanda vya mashine na viwanda nyepesi havijaanzisha vifaa na vifaa vya umeme visivyoweza kulipuka kulingana na vipimo. Wakati wa Ujumbe: Agosti 5, 2022
