Lighting device and system for emitting ambient light and direct light

A lighting device for emitting ambient light and direct light, comprising a longitudinal body and a longitudinal cover;

• where the longitudinal cover is fixed by pressure on an upper part of the longitudinal body;
• the lighting device comprising:
• a side wall on each side of the longitudinal body, where on an outer face of each side wall is fixed a light strip, which is arranged longitudinally along an entire length of the side wall of the longitudinal body
• a first diffuser which is fixed to the outer face of each side wall and is superimposed on the light strip along the entire length of the side wall;
• a second diffuser which is fixed to the outer face of each side wall and is superimposed on the first diffuser along the entire length of the side wall;
• an open channel arranged in the upper part of the longitudinal body, wherein said open channel comprises a programmable control module and a power supply module comprising an electrical connection with a power source;
• wherein the control module is connected to the light strips;
• and wherein the power supply module is connected to the control module and to the light strips;
• and whereby fixing of the longitudinal cover to the longitudinal body closes the open channel;
• an inverted U-shaped inner housing formed by inner faces of the side walls of the longitudinal body, wherein at least one luminaire for emitting direct light is fixable, the inverted U-shaped inner housing comprising:
• a longitudinal support plate configured to fit into an upper part of the inverted U-shaped inner housing, wherein the longitudinal support plate is connected to the programmable control module and the power supply module, and which comprises a magnetic medium and a lower face provided with a graphite sheet with at least two longitudinal electrical contact lines extended along a length of the longitudinal support plate;
• at least one protective piece of an electrical conductor arranged on an upper part of each inner face, wherein the protective piece fixes a position of the longitudinal support plate;
• and
• an electrical copper conductor arranged in each of the at least one protective pieces, forming an electrical power line on the inner faces of the side walls along the entire longitudinal body.
