Vim li cas lub chaw ntau pob teeb siv sijhawm ntev los qhib?
High-Intensity Discharge Lamps (HID) yuav siv tau rau cov teeb pom kev zoo hauv ntau qhov chaw. Piv nrog rau lwm qhov teeb pom kev sab nrauv, lub teeb chaw ntau pob feem ntau muaj ntau dua wattage. Lub drawback ntawm cov teeb no yog ntev npaum li cas nws yuav siv sij hawm rau lawv hloov mus rau thiab ua kom tiav. Qhov no tuaj yeem ua rau muaj teeb meem qee zaus, raws li tau pom ntawm Super Bowl XLVI thaum kev ua si raug ncua rau 34 feeb vim tias qee qhov chaw ncaws pob teeb tawm mus vim muaj hluav taws xob sab nraud.
Vim li cas nws thiaj li siv sij hawm ntev rau Hlau Halide arena teeb kom muaj zog?
Ntau qhov chaw tseem siv hlau Halide (MH) teeb pom kev zoo, uas muaj qhov tsis zoo ntawm kev siv ob peb feeb los tsim qhov tsim nyog ntawm lub teeb. Qhov tseeb, nws tuaj yeem coj lawv tsib mus rau nees nkaum feeb kom ua tiav kwv yees li 90 feem pua ntawm lawv qhov ci ntsa iab. Feem ntau, cov chaw ntau pob ua rau qhov no los ntawm kev tig lub teeb ua ntej nws tsaus ntuj kom txog thaum lub teeb xav tau tiag tiag, lawv tau ua tiav qhov tsim nyog ntawm illumination.
Thaum lub teeb tau qhib thawj zaug, cov neeg nyob hauv cov pej xeem feem ntau yuav pom qhov muag tsis pom kev. Lub teeb yuav maj mam hloov xim thiab ua kom ci dua thaum lub sijhawm sov so txog li 15 feeb kom txog thaum nws ua tiav qhov ntsuas kub zoo tshaj. Lub teeb nyob rau thiab ua haujlwm zoo.
Lub sijhawm sov so (tseem hu ua lub sijhawm ua haujlwm) yog lub sijhawm siv los piav txog lub sijhawm tuav no. Lwm qhov teeb meem txuas nrog yog tias tom qab kaw lub teeb, koj yuav tsum tau tos lub arc raj kom ntsiag to ib zaug ntxiv ua ntej tig nws rov qab. Lub sij hawm txwv yog hais txog lub sij hawm uas yuav tsum dhau mus rau lub teeb kom ntsiag to ua ntej lawv tuaj yeem tig rov qab.
Muab piv rau Hlau Halide, puas High-Pressure Sodium Teeb pib sai dua?
Kuj tseem muaj lub sij hawm lag luam thaum tig rau High-Pressure Sodium (HPS) lub teeb ua ntej nws ncav cuag nws lub zog siab tshaj plaws. Nws tuaj yeem siv li kaum feeb. Arc raj nyob rau hauv high-pressure sodium teeb tau txais kev txhawb nqa los ntawm cov qauv. Qhov nruab nrab ntawm lub qhov hluav taws xob lub raj muaj qhov kub siab heev (qhov no ua rau lub teeb ua haujlwm zoo dua). Raws li lub arc ua kom sov tsis tu ncua, cov pa roj mercury sab hauv yuav ignite thiab emit xiav teeb. Raws li lub teeb tso tawm ntawm qhov siab tshaj plaws, lub teeb txuas ntxiv kom sov thiab thaum kawg cov sodium yuav hloov mus rau vapor.
Puas yog Hlau Halide Teeb muaj kev phom sij thiab lawv mus txog qhov twg?
Hlau halide teeb tuaj yeem tawg sai sai vim yog ob qho tib si sab hauv thiab sab nrauv thiab tuaj yeem ncav cuag qhov kub ntawm 1000 degree txog 2000 degree. Oregon Xeev Cov Tub Ceev Xwm tau tshaj tawm kev ceeb toom txog qhov kev pheej hmoo no hauv xyoo 2005. Tom qab ib qho piv txwv uas 80 Lake Oswego cov kws qhia tau pom cov cim tom qab raug hluav taws xob ultraviolet los ntawm cov hlau Halide tawg tawg hauv lub tsev kawm ntawv gym, tau txais kev ceeb toom. Kev dig muag ib ntus, khaus epidermis, thiab kub hnyiab corneas yog tag nrho cov txiaj ntsig ntawm qhov xwm txheej.
Tsuas yog Hlau Halide teeb uas nws tus kheej tua yog tias lub casing tawg raug thawb rau kev teeb tsa hauv cov chaw pej xeem.
Qhov kev daws teeb meem yog dab tsi?
Nrog rau kev hloov ntawm LED teeb, peb tau pom qhov kev txhim kho zoo kawg hauv txhua txoj hauv kev ntawm kev ua kis las ncaws pob teeb pom kev zoo. Lub teeb Hlau Halide tuaj yeem poob lossis tawg rau ntau yam laj thawj, thiab yog tias lawv ua, lawv da dej molten iav rau txhua yam hauv qab no. Qhov no yog ib qho kev pheej hmoo loj tshaj plaws nrog rau Hlau Halide teeb pom kev zoo. Yog hais tias nws yog flammable, hluav taws kub zoo li qhov uas tsis ntev los no ua rau muaj kev puas tsuaj rau qhov chaw lag luam hauv New York tuaj yeem thiab yuav pib los ntawm nws.
Lub teeb LED yog qhov ruaj ntseg hloov rau Hlau Halide thiab tseem yuav hloov thiab tawm tam sim ntawd. Tib qhov teeb meem uas ua rau New York hlau halide teeb poob tsis cuam tshuam rau LED teeb.
Peb yam ua rau LED chaw ntau pob teeb zoo dua rau Hlau Halide.
Kev ua tau zoo dua, siv hluav taws xob tsawg dua, thiab txo cov nqi kho mob (dimming thiab instant rau thiab tawm).
LED teeb pom kev zoo, uas tau tsim hauv xyoo 1962, tau dhau los ua qhov tseem ceeb heev. Nws yog qhov kev xaiv zoo tshaj plaws rau kev teeb pom kev hauv chaw ntau pob vim nws pheej yig dua, ib puag ncig tus phooj ywg, thiab muab cov teeb pom kev zoo dua, qis-glare. LED teeb pom kev zoo kuj yooj yim dua los tswj thiab tso cai rau tam sim ntawd, tawm tam sim, thiab kev xaiv dimming yooj yim.
Peb ntawm BENWEI nkag siab tias kev nyab xeeb tseem ceeb npaum li cas. Hu rau peb yog tias koj xav tau kev pab cuam nrog teeb pom kev zoo ntawm koj qhov chaw sab nrauv.
