hi there!
few months back i decided to set up a new line of business and with research and etc. i decided to enter into energy sector.. more specifically i decided to jump into solar power. and importing solar- powered products into my country and market them so as to reduce the load on electricity..
for start up. i decided to work on solar powered street lights. with some homework i came to know that LED is the latest thing in light and its making its way very quickly and replacing the conventional flourescent, incandescent and sodium bulbs.
however my problem is with the understanding to their power and wattage and lumens. .i am really confused with all that.. top it all if i dont understand these all calculations i cannot propose the required solar panel and battery for any system..
can anyone please help me with this in very very simple language...
i have learned the first formula of (volt * amp = watt) also i have discovered that there are 5mm and 10mm led pieces that are commonly used in LED lights. however the availability of 1 watt one piece, 3 watt one piece and 5 watt one piece LEDs is also interesting..
also i dont know nothing about the circuits and etc.. have studied physics in scshool which i hated the most.. but with few bits of knowledge i have gained now i think it is not that bad.. i must be the way i was taught.. anyways can anyone help me with that?
according to my research and email with the LED suppliers i have learnt that 5mm LED produce 2-4 lumens (measuring scale of light) of light and to produce 1 watt of LED light you will have to put 14 pieces of 5mm LED pieces.. Similarly one watt of LED is equvilent to 4 watt of normal light (the concept of energy savers) i.e. using lesser energy and producing more light... can anyone validate that?
also with my friend electrician.. i have made some research which concluded as: 5mm of LED with some power of resistnace consumes
12mAmp. now i want to know that how much amp would it require to lit up 856 LED in either series or parallel.. i have just used the words series and paralled.. just know a little bit about them..similarly how many piece of 10mm LEDs are required to produce one watt of LED light.. what is their curernt consumption?
what should i understand if one supplier of solar street light quotes me that the lamp head has a 50 watt LED light.. how much light does this LED produces when compared to normal light? how can i calculate the curernt consumption of this light. and also how much power of battery is required to light up this lamp head for 10 hours..?
my queries may sound silly to most,, but i am a new entrant into this all.. help will be greatly appreciated?
