Definitions
- the invention relates to a housing for an operating device of a discharge lamp.
- WO 2005/008125 A1 discloses a headlight of a vehicle which has a high-pressure discharge lamp.
- the high pressure discharge lamp includes a socket in which an igniter is mounted.
- the base is surrounded by a housing which serves as an electrically conductive shield for electromagnetic radiation.
- This shield consists at least of a non-ferrous metal or an alloy of at least one non-ferrous metal.
- an external operating device is provided, which is connected via a supply cable to the lamp.
- This supply cable comprises a plug whose housing is connected to the housing of the base of the high-pressure discharge lamp.
- the housing of the plug can be made of the same metal as the housing of the base of the high-pressure discharge lamp or of a metal having a similar electronegativity as the metal of the housing of the socket, in order to reduce the risk of electrochemical corrosion of the connector.
- An inventive housing for an operating device of a discharge lamp is designed for the electromagnetic shielding of the components arranged in the housing.
- a protective layer of an electrically conductive and corrosion-resistant material is at least partially formed on the outside of the housing.
- the housing can thus be used simultaneously for EMC shielding as well as for corrosion protection due to environmental influences. Due to the electrically conductive design, the connection to the ground of a board can be ensured.
- the protective layer is formed by a Grünchromatie- tion. As a result, a relatively simple and low-effort production can be ensured.
- the selection of what is known as green chromium plating can create a Cr 6 -free protective layer which, in addition, can also take account of increased environmental protection aspects.
- the housing has a base body of magnesium casting, on which the protective layer is formed.
- the protective layer preferably comprises chromium trioxide as material components. Especially this component allows a particularly reliable corrosion protection against corrosive media of the environment. The electrical conductivity of the layer is given and the EMC shielding guaranteed.
- the protective layer for corrosion protection of the housing is formed in front of corrosive media in the environment of the operating device. It should not be a protection against electrochemical galvanic corrosion, as proposed in the prior art for the housing of the lamp base, be carried out, but for corrosive media, such as acids or salts, as in the use of the operating device, for example in a vehicle of Case can be.
- the operating device is arranged externally to the discharge lamp and connected to a supply line to the discharge lamp.
- the operating devices are exposed to high loads in terms of environmental influences. Especially when used in Vehicles are exposed to high wear due to corrosive media.
- the operating device is arranged in a vehicle and designed to operate a discharge lamp of a headlight of the vehicle.
- a housing of a base of the discharge lamp itself is formed with such a protective layer.
- the sole FIGURE shows an electronic ballast or an operating device 1 with a housing 2.
- the operating device 1 is arranged in an engine compartment of a vehicle.
- the housing 2 is designed as a magnesium casting housing and designed for the electromagnetic shielding of the components arranged in the housing.
- a protective layer 21 is formed of an electrically conductive and corrosion-resistant material. This protective layer 21 is formed by green chromating.
- the protective layer 21 is used for corrosion protection of the housing 2 against corrosive media in the vicinity of the operating device 1, such as, for example, salt mist, acids or the like. the same as they can usually occur in such a place of use of a control gear 1 in the vehicle trained.
- the operating device 1 is electrically connected via a supply line 3 via a plug 31 to a housing 4 for a socket, not shown, of a discharge lamp 5.
- an ignition device for the discharge lamp 5 is arranged in the base, not shown.
- the base and the housing 4 of the base are arranged in a receptacle 6 of a headlamp 7.
- the headlight 7 further comprises a reflector 8.
- both the EMC connection of the housing 2 and the corrosion resistance to corrosive media in the environment of the operating device 1 can be realized.
