The base preferably has a basic shape complementary to the lid or frame. In other words, the base has a round basic shape, provided that the lid / frame is round. The base preferably has a rectangular, in particular quatratische, green shape, if this is to be connected to a rectangular or square lid / frame.

The base can be made of opaque material. This makes it possible that the light generated by the LEDs expediently exits only through the lid or frame.

An electrical installation housing, in particular a branch or junction box according to the invention, can be designed both for surface-mounted installation and for flush-mounted installation.

The invention will be explained below with reference to an embodiment and with the aid of a figure.

The figure shows a junction box according to the invention 50 with a lid according to the invention 10 and a pedestal 30 , In the figure, the individual components of the junction box 50 shown in an exploded view.

The lid 10 includes an upper housing part 15 , wherein the upper housing part 15 a lid end plate 16 and a peripheral wall 17 having. The cover end plate 16 represents the end face of the junction box 50 is in the installed state of the junction box farthest from a wall. The cover end plate 16 is square. Accordingly, there is the peripheral wall 17 of four sections, each to the cover end plate 16 are subsequently formed.

Between the lid end plate 16 and the peripheral wall 17 becomes a lid interior 18 educated. The lid interior 18 is, as shown, not completely closed. Rather, he is on the lid for the top plate 16 open side formed opposite.

In the lid interior 18 is the circuit board 20 located. On the to the cover face plate 16 pointing page 21 the circuit board 20 are several LEDs 40 arranged. In the example shown, these LEDs are 40 arranged on a circular path. Thus, an optimal fluoroscopy of the lid 10 be guaranteed. Besides, on the circuit board 20 a conductor connection 45 educated. In it at least two conductors can be connected, so that a connection of the circuit board 20 on in the junction box 50 guided cable is enabled.

The lid 10 can on the illustrated socket 30 be put on. For this purpose, the housing 31 the pedestal a paragraph 32 on. For detachable connection of the lid 10 with the pedestal 30 Furthermore, connecting elements can be provided. In particular, the lid 10 Connecting pins (not shown) which can be inserted into corresponding openings of the base (not shown).

The upper housing part 15 of the lid 10 is made entirely of translucent plastic material. Preferably, the lid is an injection molded part.

The figure shows that the lid 10 in principle has a standard form with regard to standard junction boxes or standard junction boxes. The lid 10 can therefore be designed as a replaceable component. A cover of an existing standard junction box can therefore be removed and the lid according to the invention 10 be put on.

The base 30 the junction box 50 is preferably made of an opaque material. Thus, that is from the LEDs 40 generated light completely through the lid 10 or through the upper housing part 15 of the lid 10 radiated.

Due to the inventive design of the lid, it is possible to allow some basement lighting in basements or in industrial plants where usually surface-mounted junction boxes or flush-mounted junction boxes are installed.
