According to the development of the technological era, various electronic and electrical products have been widely used in people's living or working environments, and applications such as desktop computers and notebook computers have brought people to life and The convenience of work, the processing of various documents, the editing of photos or graphics, the presentation, e-mail or the application of the Internet are all the patterns that people often use, and the application of computer products is more popular, and through the computer. When performing various electronic operations, the required data must be input through the keyboard for the computer host to process according to the data input by the keyboard, and the keyboard becomes an essential tool for computer operations.

In a weak environment, the user may have difficulty recognizing the numbers and characters on the keyboard keys, which may cause difficulties in the operation. Therefore, an illuminated keyboard has been introduced on the market to improve the use of insufficient ambient light sources. The problem of input is difficult.

However, the illuminators used in the illuminating devices of the backlight modules of the illuminating keyboard are generally mounted on flexible boards (Flexible Printed). Circuit, FPC), but because the circuit configuration and material manufacturing process inside the flexible circuit board requires a large number of precise steps, the overall manufacturing cost of the flexible circuit board is quite high, and the manufacturing cost occupies about 70% of the production of the light-emitting device. The price, in turn, makes the price of the illuminating device high.

Therefore, how to solve the above-mentioned lack of inconvenience and inconvenience is the direction that the relevant industry is eager to study and improve.

Therefore, in view of the above-mentioned problems and deficiencies, the creators have collected relevant information, and through multi-party evaluation and consideration, and through years of experience in the industry, through continuous trial and modification, the keyboard lighting device has been designed.

The main purpose of the present invention is that the bottom of the backlight module is provided with at least one accommodating space, and at least one set of illuminating portions is disposed on the bottom of the backlight module, and is disposed on the surface of the printed circuit board. Locating at least one illuminator in the space, and the surface of the printed circuit board is provided with at least one connector protruding from the surface of the backlight module, and the connector is electrically connected to the mating side of one end of the arranging line, and the other end of the arranging line The docking side is electrically connected to the circuit layout of the preset keyboard to obtain power, and the manufacturing cost of the printed circuit board itself is greatly reduced compared with the manufacturing cost of the flexible circuit board (FPC), so the lighting device of the present invention uses the printed circuit. The board can achieve the goal of greatly reducing manufacturing costs.

The secondary purpose of the present invention is that a light-emitting portion is disposed around the bottom of the backlight module. Because the thickness of the member of the light-emitting portion is thick, the corresponding components in the keyboard must be dodged. The creation is installed inside the keyboard. However, since the keyboard is provided with fewer members at the edge, the light-emitting portion is installed around the bottom of the backlight module to facilitate design. To make this creation in the keyboard.

The backlight module 1 is mounted on a keyboard (not shown), and has a laminated reflective layer, a light guiding layer and a light shielding layer, and the light source can be projected to the keyboard through the backlight module 1 . In each of the key caps, the bright light is displayed by a plurality of key cap symbols or text characters, and the backlight module 1 is in the scope of the prior art, and the composition of the detail is not the focus of the present case, so the detailed details thereof will not be described in detail. The components.

And the printed circuit board 21 (PCB) of the light-emitting portion 2 is formed by drawing a circuit pattern connecting the electronic components into a wiring pattern according to a circuit design, and recreating the electrical conductor on the insulator by means of mechanical processing, surface treatment, or the like specified by the design. In other words, the printed circuit board 21 is a substrate before the electronic components, and the functions of the products are mainly to use electronic circuits formed by the circuit boards to function as electronic components. In order to achieve the effect of signal processing, and the printed circuit board 21 is in the prior art, and the composition of the detail is not the focus of the present invention, the detailed components thereof will not be described in detail; and the illuminant 22 of the light-emitting portion 2 can be It is a light-emitting diode (LED) or a cold-light sheet, etc.; and the connector 23 of the light-emitting portion 2 is soldered to the printed circuit board 21, and the soldering method can be performed by surface adhesion technology (SMT) or through hole (Through Hole) soldering.
