flickering LED lights

[miked]

i'm on my second piece of 10mm LED wedge base used as clearance/park lights on the front. replaced the 12volts 5 watts halogen with a 10mm 6 led wedge equipped with 2 resistors in parallel with each other. about 300 ohms as per the color code.

problem: LED was flickering at first. then 3 (out of 6 per piece) leds were out until all are dead.

installed another one thinking it could be the LED but problem is occuring again. replaced the previous halogen bulb and it does not flicker.

2 300 ohm resistors in parallel is equal to 150 ohms.
Mostly sir, the problem why it flickers is there is too much current passing thru the LED. Sa sobrang taas ng current, nasusunog na yung nasa loob.

T10 LEDs po ba gamit mo?

Try adding a voltage regulator IC (ex, 7805 - 7805 datasheet(1/1 Pages) ETC | THREE-TERMINAL POSITIVE VOLTAGE REGULATOR IC) instead of resistor. Putting the IC on an aluminum heatsink will also help in prolonging the life of the IC.

yap............. T10

terminal 1 is from the 12volts positive
terminal 2 is to ground return
terminal 3 is to LED positive terminal

am i correct?

Yung nakuha ko plug and play lang.. T10 28 LED









Baka nga medyo mataas yung current mo... Pumutok na po ba yung 1st batch ng LED mo? Or baka maluwag lang yung connectors, nung unang kabit ko kasi nagfiflicker din, inusli ko maigi yung wires naging ok na.

advertise nila, 100,000 hours daw.. yet here they are.. dying one by one,..
i bought one for my dome light.. napupundi isa-isa...

errr.. how do you connect the thingee (voltage regulator), and how much does it cost?

Its super cheap sir. Pero 7805 is not enough to power your dome light. 5V regulated lang kasi output nun e. Your dome light requires 12V. Kapag masyado mababa naman yung voltage, mahina output and nag-fliflicker din kapag sobrang baba.

Look for 7810 (10V regulated) if possible. LED kasi require constant voltage and current. Kaunting high fluctuation lang sa voltage, mabilis mag degrade quality niya.

ah! thanks.
san ba yan makukuha? meron ba sa auto supply? o dapat sa raon o alexan..?

For sure sir sa raon and alexan meron yan. If malapit ka sa dlsu sir, may egizmo dun.

Madami kasing cheap na led at and daling masira. Pag nag flicker yan for sure pa sira na yan. Pag me makukuha kayo ng Taiwan made mas maganda ang quality nyan at mas mahal. Kung maganda quality ng led matagal ang buhay nyan.

Meh led lights ako na nakalagay sa gauges ko... pag preno or open ako other electrical accesories, nag flicker siya(parang dim then bright uli), yesterday nilagyan ko ng capacitor yung line ng led lights, 2pcs na 2,200 uf 30v , so far hindi na flicker... stable na... hehehe.. i just solder it sa lines,,,

ano type ng led gage lights mo chief?T10 wedge or yung katumbas nung stock 3W halogen yung base?

T10 yung pang parklight... backlight siya nung gauges ko.... laki effect pag nilagyan mo capacitor...

pag meh time ako, tataasan ko pa yung uF na rating para mas stable... tingin ko mas ok din kung meh resistor para sure shot na hahaba buhay at wala kurap..

yung sakin naka tap sa ignition, pag andar ilaw na din gauges...

so wedge base yung iyo....problema eh di ako makahanap ng wedge na socket.

Pinaka ok yung mga oem na surplus na socket... Malapet kasi ako sa banawe eh, yung nakuha ko 200 a piece ang socket, oem style siya...

Its takes about 30 seconds para mag charge yung capacitor...
