Salam,

This week I have done tabulate the data that Encik Wan Remeli B. Wan Jusoh given to me. The data that I collect from "Buku Laporan Kerosakkan Asrama Perempuan" is roughly which is I only take the faulty of lighting. Encik Wan Remeli doesn't the report from January to December 2014. Therefore, he gives me the book to collect by myself. There is the table that I already done.

Statistics lighting faulty table

I already summarize the data given which is the data are complete with the reason and date report. However, I also tabulate the data on other table.

Graph from the table

The graph is shows the month from January to December and the total light has been damage. The conclusion that I can conclude on this graph is, when students start a new semester, the report regarding to the light faulty is higher.

There is a requisition from student to check all the light at stairs. However, the repaired process taking a longer time. Sometimes, it take two-three weeks to repairs the light.

The problem encountered for this week is the LED tube light holder is still not function. And I am not able to measure the wattage.

An interesting progress will be posted later.

P/s: LED tube light is more "green". More "green", less air-conditioning.

Salam,

This week I already buy fluorescent tube light and LED tube light at Jalan Pasar. The price for LED tube light is RM 60 and fluorescent tube light is RM 4 which is cheaper than LED tube light.  Actually, the cheaper LED tube light is able at the shop but unfortunately, they didn't have any stock. So, I just buy the expensive one. 

LEB tube light

This is LED tube light that I've buy. The tube light is using SMD LED module. It is type of LED module that use Surface-mounted Technology (SMT) to mount LED chips on printed circuit board (PCB). SMT is a method for producing electronic circuits in which the components are mounted. 

SMD LED module

Installation LED tube light instruction

The LED tube light does not require ballast and starter. It use the same lamp holder like fluorescent but the magnetic ballast and starter are removed. 

Comparison table

The table above shows the comparison between LED tube light and fluorescent. The life span of LED tube light is longer than fluorescent.

Lamp holder

The ballast and starter for LED tube light holder has been removed. Unfortunately, LED tube light is not function because "pop" sounds heard when the switch is ON. So, this is become my problem encountered for this week. There is something wrong with my lamp holder. The connection might be wrong.

Therefore, my plan for next week is go to Jalan Pasar. Second, I will key in the data that Encik Wan Rameli B Wan Juson (warden at UniKL BMI) give, regarding to the maintenance on lamp at Female Hostel.

I also can't measure the wattage for LED tube light. Wattage for fluorescent has been recorded and will posted later.

P/s: Save the energy. Save more, pay less.

Salam,

On this week, I have learn how to use my new toy for FYP semester 2. During on FYP semester 1 duration, I'm seeking for multi-functional meter to measure the wattage that fluorescent and LED tube light needed. And finally, I found it on lelong.com website and the company placed at Segamat, Johor (VMART TRADING). The price is RM 78 and postage cost is RM 6. 

Multi-functional mini ammater

Multi-functional mini ammeter user manual is attached together. Click the link below to shows the website that sells multi-functional meter:

lelong.com

Multi-functional meter is able to measure the wattage consumption and it also able to display the price that the user need to pay. But the rate is cant be 0.312$/watt. It able to measure the input voltage for each socket.

Wattage consumption

The picture above shows how to the multi-functional meter operates. It's awesome !

Next progress is I will buy fluorescent and LED tube light, measure the wattage for each tube light to test the efficiency of the multi-functional meter.

That's all for this week. The next information will be posted later :)
