Embodiment Construction

[0018] figure 1 A hybrid lighting lamp 1 with an incandescent lamp 2 , a gas discharge lamp 3 , a rectifier 4 , an energy store 5 and an ignition device 6 is shown. The rectifier 4 has four diodes 7-10 and its input is connected via terminals 11 and 12 to an AC line voltage source. A capacitor 5 acting as an energy store is connected to the outputs 13 and 14 on the secondary side of the rectifier 4 . The incandescent lamp 2 and the gas discharge lamp 3 are connected in series to the outputs 13 and 14 of the rectifier 4 , ie in parallel with the capacitor 5 . A second series circuit comprising the incandescent lamp 2 and the ignition device 6 is also connected to the outputs 13 and 14 . The ignition device 6 comprises a current-limiting resistor 15 , a Zener diode 16 , a capacitor 17 and a coil 18 with an antenna 19 .

[0019] On the primary side, the rectifier 4 is directly connected to the 220V line voltage. On the secondary side, there is a capacitor 5 of 22 uF, to which...

Abstract

The invention relates to a blended light lamp (1) having an incandescent lamp (2) and a gas discharge lamp (3), a rectifier (4), an energy storage means (5) and an ignition device (6). The high-pressure discharge has an operating voltage of 180 V, which can be achieved by filling a discharge vessel of the gas discharge lamp (3) with, in particular, an amount of mercury of 153 micromole / cm<3>. In this way a high total luminous flux can be obtained in the operating state.

Description

technical field [0001] The invention relates to a hybrid lighting lamp comprising an incandescent lamp, a gas discharge lamp, a rectifier, an energy storage device and an ignition device. Background technique [0002] A simple method of ballasting high pressure discharge lamps takes the form of a hybrid lamp or a single light source. In this case, a tungsten filament, which also acts as an incandescent filament, is connected in series with a high intensity discharge (HID) lamp. A hybrid luminescent lamp of this type is known from DE3224575A1. In order to start a HID lamp and keep it working, there are quite a few electronic circuits that must be operated. Also, the life of HID lamps is very short, which leads to the end result being a failure in hybrid luminescent lamps. Contents of the invention [0003] It is therefore an object of the invention to devise a gas discharge lamp in order to be able to operate the gas discharge lamp with a simple electrical circuit and to...
