Depiction of Hybrid Incandescent/Discharge Lamp

- ED28/90; ED37/120 Bulb-size -

Q - What is it intended to be, how to look like?

A - Consider it roughly as in the depiction above.

Q - At first glance, as in the previous similar cases in discussion, it seems to show all the main component parts of a HID mercury lamp: arc-tube, frame, outer bulb, stem, screw-cap. Isn't it?

A - But only at the very first! If you look it a bit more attentive, you find something else...

Q - Yes! Is it the arc-tube that looks like a linear halogen lamp?

A - Well, isn't?!...

Q - Then?

A - You guess it!... The incandescent filament is in the midst of the arc tube, from one end to the other.

Q - So, to what is it related at most? Is it to the halogen lamp or rather to the discharge lamp?

A - Consider it related to both of them. It is a hybrid lamp. The discussion will make relevant to which one is it related at most, or to what extent of any of them...

Q - OK! Let's go a bit to the arc tube in the depiction on top. It looks really like a linear halogen lamp, isn't it? And, even by its length, too. It seems much longer than the HID arc tubes. What makes the difference between that and the lamp in discussion?

A - Yes, it is resembling at best a halogen lamp. But, it has at each end one electrode for the electrical discharge, as are in the HID arc tubes.

Q - And we find also in this depiction that each one of the discharge electrodes is directly linked to each one of the ends of the filament. So, can we conclude that the electrical discharge process is or works in parallel circuit with the incandescent filament?

A - Yes! It might be considered one variant of this type of lamp. At least in the experimental stage.
