Embodiment Construction

[0036] figure 1 A side sectional view of a lighting device in the form of a retrofit lamp 1 for replacing a conventional MR16 lamp according to a first embodiment is shown.

[0037] The retrofit lamp 1 has a housing 2 which is open on its front side and has two feedthroughs 3 on its rear side. A driver 4 in the form of drive electronics is accommodated in the housing 2 . Fastened on the driver 4 , for example welded, are two contact pins 5 , which protrude partially through the lead-through 3 . The contact pins 5 together with the counter area 6 of the housing 2 form a socket of the type GU5.3. The sockets 5, 6 are suitable for use in matching lamp sockets.

[0038] The front open side 7 of the housing 2 is covered by a cover 8 on which a base body 9 for the semiconductor light source in the form of an LED 10 is arranged on the outside. Here, the LED 10 emits its light into the front half area. Not shown but there could be a light-transmissive (transparent or opaque) cove...

Abstract

The invention relates to a lighting device (1) which comprises a housing (2) which is internally provided with a driver (4) which is in contact with at least one contact pin (5) and guides the at least one contact pin (5) to pass through the housing (2) so as to form a small tube rest (5,6), wherein the at least one contact pin is retained to the housing (2) by means of an insurance element (11) which is sleeved to the contact pin (5). A method for manufacturing the light device (1) includes at least the following steps: providing at least one clamping disc (11) on a carrier; guiding the driver to the housing by passing at least one contact pin (5) through a passing through portion (3) of the housing (2); pushing the at least one clamping disc (11) to the at least one contact pin (5) from the external side until being stopped by the housing (2). Specially, the light device herein applies to semiconductor modified light, in particular MR16 type light with small tube seat.

Description

technical field [0001] The invention relates to a lighting device having a housing in which a driver is installed, the driver being connected to at least one contact pin, wherein the at least one contact pin is guided through the housing to form a small tube base. In particular, the invention can be applied to semiconductor retrofit lamps, in particular lamps with small tube bases, in particular of the MR16 type. Background technique [0002] Hitherto, LED retrofit lamps have been assembled from multiple components in a complex manner in multiple work steps in a production line or manually. Some LED retrofit lamps have small tube sockets. To manufacture these retrofit lamps, the contact pins or pins of the LED lamps are soldered during assembly of the electric driver. During the final assembly of the LED retrofit lamp, the driver is inserted into the housing and the contact pins are guided out of the housing through holes or feedthroughs provided for this purpose. The con...
