The invention relates to a PAR lamp assembly with a built-in lamp, in particular a halogen built-in lamp, which is inserted into a socket and at least partially surrounded by a reflector, wherein the base and the integral lamp are connected via contact springs and the reflector is covered by a lens. The invention further relates to a socket arrangement, in particular for a PAR lamp arrangement.

State of the art

PAR (Parabolic Aluminized Reflector) lamps are used in large numbers due to their compact design and cost-effective production in the general and professional lighting technology, for example in the discotheque lighting or for architectural lighting applications.

Such, for example from the US 6 053 623 . EP 0 584 071 B1 and the EP 0 550 934 B1 known PAR lamps have a reflector body made of pressed glass and coated with aluminum reflector body with a light source inserted therein. The reflector body is typically formed as a concave paraboloid, wherein the light source is preferably arranged in the focus of the reflector and closed by a cover. Due to their good light quality and long service life, halogen incandescent lamps (halogen torches) with or without enveloping bulbs are increasingly being used as the light source. The attached to the reflector body cover can smooth or to influence the optical properties with a Surface structure, for example, be performed faceted and also serves as a safety device in the case of a bursting halogen burner.

A disadvantage of the above-described solution is that such PAR lamps have a high weight and are very expensive due to their complex design and manufacturing in the production.

Presentation of the invention

The invention has for its object to provide a PAR lamp assembly with a built-in lamp, in particular a halogen built-in lamp, which has a reduced weight in a simplified manufacturing process.

This object is achieved by a PAR lamp assembly with the combination of features of claim 1 and by a base assembly having the features of claim 15. Particularly advantageous embodiments of the invention are described in the dependent claims.

The PAR lamp arrangement according to the invention has a built-in lamp, in particular a halogen built-in lamp, which is inserted in a socket and at least partially surrounded by a reflector, wherein the base and the integral lamp are connected via contact springs and the reflector is covered by a lens. The reflector is made of aluminum and is provided with a reflective surface or coating. By using the aluminum reflector, which is lighter in relation to a conventional glass reflector, a reduced weight of the PAR lamp assembly is achieved with a simplified manufacturing process.

The reflector is preferably connected by forming, in particular by crimping a peripheral portion of a peripheral wall of the reflector with the lens, wherein the limited space of the reflector and diffuser is filled in contrast to the known solutions with air.

A base assembly for a PAR lamp assembly according to the invention has a base into which a contact spring assembly is snapped.

Base and built-in lamp are connected via the contact spring arrangement. This takes over both the electrical contact and the mechanical fixation of the built-in lamp in the reflector, so that can be dispensed with separate power supply. The inclusion of the built-in lamp via contact springs allows a variation of the mounting position of the built-in lamp in the reflector and thus an adaptation to different versions of built-in lamps, eg. At other crushing or contact pin lengths. Furthermore, it is possible by receiving the built-in lamp via contact springs, an improved mounting of the recessed lamp with reduced manufacturing costs.

The contact spring arrangement preferably forms on the lamp side a clamping region for encompassing a pinch of the integral lamp.

The holder of the built-in lamp can be advantageously via at least two formed in the clamping area knob-like projections, which can be brought into contact with two side surfaces of the pinch, continue to improve.

In order to limit the depth of immersion of the recessed lamp in the contact spring arrangement, this has at least one slot-shaped insertion section into which at least one cam of the pinch of the recessed lamp is insertable and fixable there.

The insertion section is advantageously limited on the lamp side by corner regions which engage behind the cam of the pinch and hold the integral lamp in the contact spring arrangement.

In order to facilitate the insertion of the pinch, the corner regions are bent in an embodiment on the lamp side at least partially outward.

In a particularly preferred embodiment of the invention, the contact spring arrangement has at least two contact springs for electrically contacting the built-in lamp. Preferably, the contact springs are designed to be identical, whereby the production cost of the PAR lamp assembly is further reduced. Due to the electrically conductive contact springs, can be dispensed with additional electrical connections of the recessed lamp.

The contact springs preferably each form at least one spring tab, which is bent out for connection to the base. The base and the contact springs are designed such that they are plugged into each other and thereby connectable.

It has proved to be particularly advantageous to design the contact springs as sheet-metal stamped bent parts which, at least in sections, have an approximately clamp-shaped cross-section.

According to a preferred embodiment, the integral lamp has two contact pins which emerge at the bottom of the pinch and are each provided with a power supply with integrated electrical fuse, wherein the power supply lines are returned in the direction of two plane-parallel surfaces of the pinch. Due to the approximately U-shaped bent back in the direction of the recessed lamp power supply, a small height of the built-in lamp used in the contact spring assembly is achieved.

Preferably, the power supply lines are electrically connected to contact lugs of the contact springs, in particular welded or soldered.

For accommodating the power supply lines of a built-in lamp which can be inserted into the base, the base preferably has at least one recess.

In order to achieve a secure hold of the reflector on the base, preferably a reflector neck of the reflector and a holding region of the base are connected by at least partially plastic deformation, preferably crimping.

The built-in lamp can be carried out preferably in Quetschnoppentechnik or with a beam frame. Such Halogeneinbaulampen be produced inexpensively for general lighting in large quantities, thereby further reducing the manufacturing cost of the PAR lamp assembly according to the invention.

Preferably, the spring tabs 116 and the mounting recesses 122, 124 are dimensioned such that the spring tab 116 engages behind the projections 148, 150 formed by the T- and slot-shaped portions. For receiving power supply lines 58, 60 and fuses 62, 64 of insertable into the base 10 built-in lamp 2 of the ceramic base 10 has a blind hole-shaped recess 73 which extends along its longitudinal axis. As a result, a small overall height of the built-in lamp 2 used in the contact springs 12, 14 is achieved.

In the FIGS. 12 to 13 an embodiment of a PAR lamp assembly is shown, in which the built-in lamp 2 is designed with a beam frame for holding the coil.

According to FIG. 12 showing a three-dimensional view of a base assembly 4 according to the invention, the integral lamp 2 is designed as a halogen incandescent lamp (halogen burner) in beam frame technology. Such a halogen incandescent lamp 2 has a helix 152 which is provided, for example, with four helical sections 154 and is fixed in position in a piston 158 via a beam frame 156, which has two helical holders 155 with approximately U-shaped curvatures 157 and a hook-like retaining element 159. The two spiral holders 155 and the holding element 159 are fixed in their position relative to each other by a transverse bar 161 made of quartz glass, wherein the two coil holders 155 lie in one plane. The piston 158 is above, already in FIG. 6 explained, one-sided pinch seal 44 sealed, in which the two end portions of the coil 152 are connected via power supply lines and one molybdenum foil 46 with led out of the pinch seal contact pins 48.
