Illuminated keyboard and backlight module

An illuminated keyboard, comprising:

• a keyboard module, comprising:
• a bracket;
• and
• at least one first key cap, disposed above the bracket;
• a circuit board, wherein at least one side-emitting element and a top-emitting element are disposed at the circuit board;
• and
• a backlight module, disposed below the keyboard module and comprising:
• a light guide plate having a slot;
• wherein the at least one side-emitting element extends into the slot such that the light emitted from the at least one side-emitting element enters the light guide plate, the light passes through a light output zone of the bracket and illuminate the at least one first key cap,
• wherein the bracket comprises a first segment and a second segment, an orthographic projection of the at least one first key cap projected to the bracket is located at the first segment, and an orthographic projection of the top-emitting element projected to the bracket is located at the second segment, and
• a touch module or a second key cap disposed above the second segment of the bracket so that the top-emitting element is located below the touch module or the second key cap and emits towards the touch module or the second key cap,
• wherein the circuit board comprises a first surface facing towards the at least one first key cap and a second surface facing away from the at least one first key cap, the top-emitting element and the at least one side-emitting element are disposed on the first surface, the circuit board is disposed below the backlight module,
• the backlight module comprises a reflector, the reflector is located between the light guide plate and the circuit board, the reflector comprises a least one accommodating hole accommodating the top-emitting element and the at least one side-emitting element.
