An electrical light has a tubular sheet-metal housing centered generally on an axis and formed with a plurality of angularly spaced, radially inwardly projecting, and radially elastically deflectable spring tongues. A socket in the housing holds a light bulb. A cup-shaped glass lens has a dome formed with a generally cylindrical collar dimensioned to fit into the housing with the dome fitting over a light bulb in the socket. The collar is formed with a plurality of angularly spaced and radially outwardly open L-shaped grooves each fittable with a respective one of the tongues. Each groove has an axially extending and open leg and an angularly extending leg. The angularly extending legs each have an outer flank and an inner flank between the respective outer flank and the dome.

Two substantially identical LED modules each have a nonconductive base having a straight edge and a pair of faces, at least one LED on the base, and two conductive traces on the base connected to the LED and forming on one of the faces inner and outer contacts spaced along a line perpendicular from the edge with the outer contact between the inner contact and the edge. The modules are juxtaposed at the edges with the lines aligned with each other and the one faces generally coplanar. A clip has a nonconductive body bearing on the one faces of both of the bases at the edges and two respective conductors on the clip body having portions spaced apart along the aligned lines and bearing on the contacts of both bases. The clip body and conductors are pressed against the bases to engage the conductors with the respective contacts and secure the bases together.

The push-in/push-out lampholder has a guide track for an unlocking member which is permanently coupled to a fixation member. The guide track may be heart-shaped and be partly traversed by the unlocking member when a lamp cap is pressed into the lampholder. The lamp cap must be released if it is to reach an operational position under the influence of a spring. The fixation member permanently coupled to the unlocking member is then in engagement with a profile of the lamp cap and retains the lamp, pressed against contact members. It is not until a second, separate push is given that the unlocking member continues its path through the guide track. In a special embodiment, the fixation member and the unlocking member are combined into an integrated member, which may be a ball which is enclosed in inwardly narrowing bores of a cylindrical ball holder and in the guide track. The lampholder can be slim and can be manufactured mainly from metal or from synthetic resin.

Push-in/push-out lampholder

The electrical connector block comprises an insulating body and a plurality of conductor terminals mounted in it of which at least one is a protective conductor terminal. It is provided with an additional contacting member which passes through the base of the insulating body facing a connector block support and has at least one exterior plug which can directly make contact in a socket in the connector block support. The protective conductor plug can be mounted in the connector block during manufacture of the connector block or also subsequently to making the connector block without having to dismantle it. The structure and positioning of the protective conductor plug or plugs allows an easy automatic connection to the protective conductor by plugging the conector block into the connector block support.
