Abstract: A gas stove with flame detection comprises a switch module, a flame detection module and a processing module. The switch module generates an ignition signal when a gas stove flame is lit. The flame detection module generates a first light wave signal when the flame detection module detects light wave having wavelengths of about 400 nm to 500 nm, and the flame detection module generates an second light wave signal when the flame detection module detects light wave having wavelengths of about 600 nm to 780 nm. The processing module turns on an air drafting device and an alarm device when the processing module receives the first light wave signal and the second light wave signal at the same time or only receives the second light wave signal.

Abstract: A heat sink structure for high power LED lamp includes a heat conducting lamp holder, a heat conductor and a heat sink. The heat conducting lamp holder is made of highly heat-conductive material to provide a smooth surface for firmly holding an LED lamp. The heat conductor is made of highly heat-conductive material for linking the heat conducting lamp holder and the heat sink. The heat sink includes a plurality of heat sink fins made of highly heat-conductive material. The plurality of heat sink fins are arranged radially to form a porous center structure with no occluding junction, thereby implementing a heat sink structure which can provide omnidirectional heat dissipating capability and good convection capability to let hot air to rise naturally for high power LED lamps.

Abstract: A spring enhancer comprising a body installed between the space of the springs; the present invention is an extra device without changing any original structure and is directly installed onto the original springs, such scheme is simple in structure and easy to install, not only solve the tedious and high cost to re-equip the shock absorbers of automobiles and also improve the over-leaning condition due to the deformation of springs.
