Abstract: A fluid-convection heat dissipation device includes at least one heat dissipation module, at least two baffles, and a heat dissipation fluid. The heat dissipation module forms at least one internal receiving space and has an outside surface to which at least one light emission element is attached. The baffles are arranged in the receiving space to divide the receiving space into a plurality of convection channels that are in fluid communication with each other. The heat dissipation fluid is received in the receiving space as a convection medium displaceable in a circulating path along the plurality of convection channels.

Abstract: Disclosed is a light guide device for a water spraying device. The light guide device includes a light guide block that is a light-transmitting block having a refractive index greater than one. The light guide block has a circumferential face in which a plurality of mounting holes is defined for receiving and retaining light-emitting elements. A plurality of through holes is defined through the light guide blocks and extends in a direction substantially perpendicular to the mounting holes. Each through hole has a roughened inside surface. The through holes are in fluid communication with water discharge holes of the water spraying device so that water jets supplied from the water spraying device can flow through the through holes for discharging. The light-emitting elements emit light rays that transmit through the light guide block and get into the through holes and the water jets. The rays are subject to reflection inside the water jets to provide lighting or luminous effect to the water jets.

Abstract: A brake alarm device integrated circuit is disclosed. When a high voltage is inputted into a first primary input, current flow through the first diode and then a positive bias will cause the second integrated circuit to light up a plurality of first LEDs. When a high voltage is inputted into a second primary input end, the first resistor will conduct the first integrated circuit. When a high voltage is inputted into the third primary input end, current therethrough and then the third resistor will conduct the third integrated circuit; a positive bias of the second integrated circuit will be suppressed to a low level. Thereby, the second integrated circuit will be actuated; then the first LEDs will extinguished; if the high voltage is stopped to input to the third primary input end, the first LEDs will light up. Thereby, different lights are used to represent different brake condition.
