Abstract: An impact-protection safety structure is provided for a headwear, including an impact protector formed by a knitted resilient net lining having a suitable thickness and fixed at a suitable location on an inside surface of the headwear to serve as padding, whereby when the head of a wearer is subjected to impacts, proper buffering and protection are ensured so as to realize safety and protection against impact to the head after the headwear is worn.

Abstract: A backlight module includes at least a light source generator, a housing, at least a thermal detector, and an inverter. The thermal detector is disposed in the housing for measuring the temperature within the housing when the light source generator is operating, and the inverter is electrically connected to the thermal detector and the light source generator for adjusting the electrical current of the light source generator according to the temperature measured by the thermal detector.

Abstract: A back light unit having a light guide plate, a light guide bar connecting to the light guide plate, at least a white LED light source, and at least a color LED light source. Each of the LED light sources is positioned at a side of the light guide bar. The color LED light source compensates white light from the white LED light source that cannot produce preferable white light. Accordingly, the back light unit can produce white light that provides preferable color saturation to a display in cooperation of the white LED light source and the color LED light source.
