Abstract: An uniformly self-luminous keyboard device comprises a housing and a keyboard unit. The housing includes an upper casing and a lower casing, which can be assembled together. After the upper casing and the lower casing are assembled together, an accommodation space is formed therebetween. The upper casing has an opening interconnecting the accommodation space. The keyboard unit is arranged in the accommodation space and includes a plurality of press members passing through the opening and moved by a force to have a displacement, and a baseplate supporting the press members. A light conduction space is formed between the baseplate and the lower casing. A light emitting unit is arranged inside the light conduction space. The height of the light conduction space decreases with the distance to the light emitting unit, whereby light is uniformly distributed over the bottom of the keyboard unit. Thus is achieved the uniformly self-luminous keyboard device.

Abstract: A luminous keyboard comprises a housing, a keyboard and a light emitting portion. The keyboard and light emitting portion are held in the housing. The light emitting portion includes at least one housing trough and a lighting element held in the housing trough. The housing trough has at least one first recess portion and at least one second recess portion on the periphery. The first recess portion and second recess portion have respectively an inner wall formed a first curved surface and a second curved surface. The lighting element generates light projected to the first and second recess portions, and the light piercing through the first and second curved surfaces is transmitted towards the concave directions of the first and second recess portions. Thus the light advancing direction in the light emitting portion can be effectively controlled.

Abstract: A power regulator, power control system and the method thereof are provided. A detecting device receives a feedback signal from a resistive load device, and outputs a control signal, which could be a voltage or a current. While receiving the control signal, the power regulator outputs a drive voltage in a proportional way. In the proportional way, full power drive voltage is outputted in a continuous output time period and is stopped outputting in a continuous non-output time period. The resistive load device receives the drive voltage and then outputs the feedback signal to the detecting device. Similarly, in the proportional way, the full power drive voltage is outputted in the continuous output time period and is stopped outputting in the continuous non-output time period. Thus, it is able to decrease the amount of harmonic waves.

Abstract: A backlight keyboard module includes a keyboard portion and a light emitting portion located on the keyboard portion. The keyboard portion includes a baseboard, a keycap movable up and down relative to the baseboard, and a circuit board depressed by the up and down movements of the keycap to output signals. The light emitting portion has a shading plate located beneath the keycap and a light emitting element to provide light. The shading plate has an opening corresponding to the keycap to allow light of the light emitting element to pass through and project to the keycap. Thus the keyboard only illuminates light on the keycap location in a non-uniform manner to highlight the location of the keycap to improve keystroke accuracy.

Abstract: A keyboard for reducing assembly procedures mainly includes a baseboard, a driven mechanism and a holding board located on the baseboard. The baseboard has at least two horizontal detent portions forming a holding space therebetween. The driven mechanism has a coupling member and an elastic member. The coupling member has a retaining portion at one side held in the holding space and a keycap at another side supported by the elastic element. The holding board is located between the baseboard and keycap, and has an opening corresponding to the driven mechanism and a vertical detent portion to cover the holding space to confine the driven mechanism. Thus the horizontal detent portions and vertical detent portion can confine the horizontal and vertical movements of the driven mechanism to form anchoring. Assembly processes of the driven mechanism are simplified and total assembly time is shortened to facilitate automatic production and improve productivity.

Abstract: A roof ventilation assembly has a ridge framework corresponding to a vent on a roof, a top cover, front and rear panels and two baffler assemblies. The two baffler assemblies are respectively mounted on two sides of the ridge framework leaving two gaps between the baffler assemblies and the top cover. When heated air under the roof rises, the heated air goes through the vent and out of the slots. Therefore, the heated air can be expelled by the roof ventilation assembly cheaply and easily, without requiring maintenance and external power source.
