In a similar manner to fig. 8b, the next lamp unit 1 is mounted with the next mounting unit 20 and the mounted lamp units are fixed to the predetermined positions until the mounting of the last lamp unit 1 to the predetermined positions is completed.

In only one connection location in the installation unit installed to the last lamp unit 1, a contact is accommodated which is electrically connected to the corresponding electrical contact point.

In the lamp system shown in fig. 6b and fig. 8a to 8b, since the connection position is disposed on the mounting unit, not on the central portion of the back of the lamp panel, the user can have a larger operation space to insert or press the contactor onto the mounting unit, especially for users with poor eyesight or inconvenient hands and feet, so that the connection of the connector has a larger operation space, and the installation of the connector to the lamp unit is easier to operate. In addition, the contactors with higher cost, such as spring metal or other terminals, are arranged at two ends of the connector instead of the lamp panel, so that the lamp units can be connected together by the connectors as required, waste of the terminals with higher cost, such as spring metal, is avoided, and the manufacturing cost is reduced.

Fig. 9a to 9c show the installation process of one lamp unit. As shown in fig. 9a, the lamp panel 10, the mounting unit 20 and the connector 3 are in a separated state. In fig. 9b, a plurality of combinations of the mounting unit and the lamp panel may be obtained in this way by mounting the mounting unit 20 to the lamp panel 10 to obtain a combination of the mounting unit and the lamp panel. As shown in fig. 9c, in the assembly, the contactor 301 at one end of the connector 3 is pressed into one connection position of the mounting unit of the assembly.

Optionally, a method of installing a luminaire system comprises: correspondingly mounting the mounting unit to the central part of the back of the lamp panel to obtain a preset assembly of the mounting unit and the lamp panel, and enabling the connection positions on the mounting unit to correspond to the openings in the central part of the back and the electric contact points in the openings one to one; connecting a contactor at one end of a connector to a connecting position of the mounting unit in a preset assembly, so that the contactor at one end of the connector is electrically connected with an electric contact point in the opening of the back center part corresponding to the connecting position; and step three, mounting a preset assembly to a preset position through a mounting unit in the preset assembly, and step four, pressing a contactor at the other end of a connector into a connecting position of the mounting unit in another preset assembly to enable the contactor at the other end of the connector to be electrically connected with an electric contact point in an opening of the back center part corresponding to the connecting position of the mounting unit in the other preset assembly, wherein the lamp system comprises a power line, and the contactor at one end of the power line is connected into the connecting position of the mounting unit in the first preset assembly in the mounting process of the lamp system to supply power to the lamp system.

Specifically, during installation of the luminaire system, in particular, first a plurality of assemblies of the mounting unit and the lamp panel are obtained as shown in fig. 9 b. For a first assembly of the plurality of assemblies, the contact at the end of the power cord is pressed into a connection location of the mounting unit of the assembly such that the contact makes electrical contact with the corresponding electrical contact point, where the structure of the contact at the end of the power cord is identical to the structure of the contact at the end of the connector described herein. Then, the contact of one end of one connector is pressed into another connection position of the mounting unit of the first assembly so that the contact is in electrical contact with the corresponding electrical contact point. Finally, the first assembly is mounted to the predetermined position via the mounting unit in the first assembly, for example, by an adhesive or a non-marking nail on the back surface of the substrate of the mounting unit. The installation process described above is similar to that of fig. 8a, and can be understood with reference to this figure.

Then, the contact at one end of the other connector is pressed into the other connection site of the mounting unit in the next assembly. Finally, the next assembly is mounted to the predetermined position via its mounting unit, for example, by an adhesive or a non-marking nail on the back surface of the mounting unit substrate in the next assembly. The installation process described above is similar to that of fig. 8b and can be understood with reference to this figure.

In a similar manner to that described above, a further next assembly can be mounted to the predetermined position until the mounting of the last assembly to the predetermined position is completed.

It is to be noted here that in only one connection location in the mounting unit of the last assembly, a contact is accommodated which is electrically connected to the corresponding electrical contact point.

Through the mode, the installation unit can be installed to the lamp panel when the lamp system leaves a factory, a user directly presses the contactor of the connector into the clamping groove when the lamp system is used, and therefore the lamp unit can be spliced and combined, and the lamp system is easier and more convenient to install.

The case where the mounting unit is first mounted to the lamp panel and then the connector is mounted has been described above, but the present disclosure is not limited thereto, and the connector may be first mounted on the mounting unit and then the mounting unit may be mounted to the lamp panel.

In the lamp system shown in fig. 7 and 9a to 9c, since the connection position is provided on the substrate of the mounting unit, the connector can be fixed to the mounting device by pressing before or after the mounting unit is mounted to the lamp panel, so that the connector has a larger operation space for connection and the mounting of the connector to the lamp unit is easier to operate.
