A light emitting module board which is compatible with a plurality of screen sizes and is used for a backlight apparatus of a liquid crystal display panel is provided. A light emitting module includes a first connectorand a second connector, each including a plurality of cathode terminals and at least one anode terminal, at each end of the board, and can be connected to another one to each other through the connectors in multi-level. A cathode wiringfor supplying a cathode control signal includes first cathode wirings which connect the cathode terminals of the first connector and light emitting bodies to supply a control signal to the light emitting bodies in the light emitting module, and second cathode wirings which connect the cathode terminals of the first and second connectors to supply a control signal to the light emitting bodies on a downstream light emitting module.

Light emitting module, light emitting module unit, and backlight system

An LED module comprises: an insulating substrate in plate form; first main and sub terminals for connection to an external circuit formed near the first side of the insulating substrate; second main and sub terminals for connection to an external circuit formed near the second side opposite to the first side; three or more connecting wires formed on the insulating substrate for connecting LEDs continuously aligned at a distance from each other in series; LEDs individually connected between the connecting wires adjacent to each other and connected in series in a same direction; and a first passing wire formed on the insulating substrate for electrically connecting the first sub-terminal to the second sub-terminal, wherein a first connecting wire located on one side is electrically connected to the first main terminal, and a second connecting wire located on the other side is electrically connected to the second main terminal.

LED module and LED light source apparatus

An LED substrate comprises holes having an elliptical shape through which fixing screws are inserted. The fixing screw has a head portion, an unthreaded neck portion whose diameter smaller than that of the head portion, and a threaded shaft portion whose diameter smaller than that of the neck portion. A major axis of the hole is larger than the diameter of the head portion, and a minor axis thereof is smaller than the diameter of the head portion and larger than the diameter of the neck portion. The LED substrate further comprises counterbored recesses to which anchoring claws provided in a cabinet are fitted. A width of the counterbored recess in a direction of the major axis of the hole is larger than that of the anchoring claw. The counterbored recesses are formed on both of two sides of the LED substrate facing each other in a first direction.
