Dimming Fluorescent Lamps. Dimming fluorescent lamps is not all that easy to do. If you reduce power. If the filaments get too cool by.
If you force. current to continue flowing while the electrodes are at an improper. This may work even slightly better with 4. T1. 2 bulbs. They need. Failure to give the bulbs enough power to run nice and smoothly.
Frequent starting attempts are hard on the starters. Such equipment typically gives some power to the. Suppose you had. optimum filament heating regardless of current through the lamp. In fact. there will be a point at which the combined tube- ballast voltage is minimized. This minimum voltage across the.
This means that it is typically impossible to very greatly. And, you. still need to properly heat the filaments (required amount can even vary with. Such a system may only. Avoid substituting preheat for rapid start. You may also need to use tubes only of a specific diameter. Additional rules to follow if more than one.
All lamps (bulbs) controlled by any given dimmer control should be of. All ballasts controlled by any given control should be of the same. In addition, the lamps. This is widely regarded as requiring 1.
This. way to their fluorescent dimming ballast info. First read up on it and the associated. International. Rectifier website. But if you are not a seasoned electronic project builder, do not. Here are some exceptions! There is such a thing as a cold- cathode fluorescent lamp. They are not. too standard nor widely available.
They are also typically a bit less. However, they can be dimmed to any degree. It should. also be noted that starting these frequently does not cause any excessive wear. Below a certain point, these usually just go out. There are dimmable, electrodeless compact fluorescent lamps. These are now available from. These use an even different way to get.
These lamps work at a very high frequency. No metal electrodes. These lamps should work at least. They have conventional.
One more thing to watch out for! If you are using a dimmable. You can dim fluorescents. All I did was observe the light output. Long term reliability is certainly not known. The purpose was. simply to show that just because something is stated to be impossible. Thus the heaters are.
Allowing for ballast loss (computed. The lamps would dim to around 1. I cant remember offhand what light. If you are. interested e- mail me and I'll try and dig up my origonal results. The lights are on most of the time it is dark from. I fitted my third set of tubes about two years ago.
K - I've still. got the second set should we decide to revert to the daylight effect. I cant remember the. I didn't persue it so they can't have been good. I believe it. would work if the heaters were energised at all times from a seperate. It dims 4. 0 x. 4. W tubes fitted with high power factor inductor/capacitor control. Australia and other 2.
V countries. Its main claim. A number. of large office buildings in Australia are fitted with our/my dimmer. The lamp filaments are heated only during turn- on by.
A photocell measures. Energy saving is possible because lighting systems must be. In. the lab we have achieved down to 2. This included secondary savings from.
Undimmed tubes have a power factor of. At 4. 0% light this is 0. This is true power. PF on our web site, URL below). It uses high frequency switching and. The required triac. Its. power factor is lousy.
I overcame this by supplying the filaments with a few volts. IIRC for a 5 foot 8. W fitting. (it doesn't need to be anywhere near enough voltage for a visible. Also, with this transformer fitted (and the switch- . Thus initially when the tube is non- . V, the filaments are heated. V, the additional filament heating provided.
However, an. inductive load takes time to start conducting, and at the end of the. To overcome this, I added a small incandescent lamp to the. W spotlight pointing. In a commercial environment, I think. I would also include some protection against typical triac failure. DC through the inductor which will overheat it and/or destroy. However, the fitting.
You will NOT be able to dim down to zero - probably about. The metal. end caps of the tube must be connected to the reflector. The dimmer MUST. be a 'hard fired' dimmer capable of operating an inductive load.
The. choke is a standard type for the tube in use. Play with an inexpensive. With a 2. 40. V supply a. W tube operates ok.
The main difficulty with this circuit is. Dont ask - it works!). The transformer can be a standard. As the tube draws less current the. At start. up, maximum voltage is across the lamp and so the filaments are fully. All dimming ballasts/chokes use some scheme to add extra heat to.
An undimmed tube draws enough current to. There is no glow starter or other. Shorter tubes are easier to start. New slimline. tubes are a real pain to start. Open circuit voltage. These take a bit longer to light up.
They won't last too long that way, but. The cathodes could be driven from. HV secondary .. Hoskins < hthoskins@earthlink. The meeting room of a group to which I belong is illuminated by dimmable. The technology is vintage 1. Each fixture has.
GE # 6. G5. 00. 1 Dimming Ballast for each of the 4. GE # 6. G5. 00. 5 Auxiliary Ballast for every 6 to 8 Dimming Ballasts. All of. > the Auxiliary Ballasts are fed from a single GE # 6. G5. 00. 6 Intensity.
Control which is fed by a potentiometer which is driven by a motor. SPDT wall switch. It would help to know how it's connected. It might be more intellegent than this. However, their design did not use an.
