RU96702U1 - CARTRIDGE FOR LIGHTING INSTRUMENT ON THE BASIS OF LEDS - Google Patents

Abstract

 An LED-based lighting fixture cartridge comprising a detachable dielectric housing, a threaded insert, a central contact and a lead-in mounting unit, characterized in that it further comprises a current transducer and opening contacts for disconnecting the current transducer from the power supply when removing the lighting fixture from cartridge.

Description

The utility model relates to electrical engineering and can be used in the manufacture of cartridges for lighting devices based on LEDs.

A known lamp holder comprising a housing with an internal threaded surface, a central and lateral contacts and a mounting block of conductive wires (RF patent No. 2193809, H01R 33/22, 2002).

Also known is a cartridge for a lighting device based on LEDs, comprising a detachable housing made of dielectric material, a threaded insert, a central contact and a mounting block for conductive wires (RF patent No. 2297082, H01R 33/22, 2007).

However, the design of these cartridges does not provide the conversion of the alternating current of the power supply network to the stabilized high-frequency voltage required to power the lighting devices based on LEDs.

In the above patent of the Russian Federation No. 2297082, this problem was solved by installing a current converter in the socket of a lighting device inserted into a cartridge. However, with each replacement of a failed device, a new current converter is necessary, which is not economically feasible.

The basis of this utility model is the task of developing the design of the cartridge, which provides power to the lighting device based on LEDs from an alternating current network with the conversion of the latter to a stabilized high-frequency voltage.

The problem is solved in that the cartridge for a lighting device based on LEDs, containing a detachable housing made of dielectric material, a threaded insert, a central contact and a power supply mounting block, further comprises a current converter and disconnecting contacts for disconnecting the current converter from the power supply when removing the lighting device from the cartridge.

Further, the utility model is illustrated by an example of its implementation with reference to the drawing, which shows a diagram of the proposed cartridge.

The cartridge contains a detachable housing 1 of dielectric material, inside of which there is a threaded insert 2 of electrically conductive material, a current transducer 3, opening contacts 4, 5, an insulating washer 6, in the hole of which the pusher 7 moves freely. A central contact 8. There is a central contact 8. The cartridge is equipped with the mounting unit 9 of the lead wires 10, 11.

The cartridge works as follows. In the absence of a lamp base in the cartridge, contacts 4, 5 are in the open state. In this case, under the action of the elastic contact 4, the pusher 7 and the central contact 8 are raised up. Thus, the current converter is in de-energized mode. When installing the base of the lighting device in the cartridge, the central contact 8 lowers. The force through the pusher 7 is transmitted to the opening contact 4 until it closes with the contact 5, thus including the current Converter in an external power supply.

The use of the proposed cartridge can reduce the cost of manufacturing a lighting device, since there is no need to install a current converter in the base of the device. Disconnecting the current converter from the power supply in the absence of a lamp base in the cartridge leads to energy savings.
