Abstract:
A lighting device with a multiple cooling layer structure has at least one mounting heat conductive block, at least one light assembly and multiple heatsinks. The mounting heat conductive block has a front end, a rear end, a side and at least one shoulder. Each shoulder is formed at the side of the mounting bracket. The light assembly is mounted on the front end of the mounting bracket. Each heatsinks is mounted on one of the shoulders and the rear end of the mounting bracket. When the lighting device generates heat, the heat is able to drive away from the mounting bracket to the heatsinks. The lighting device is able to cool down. The mounting heat conductive block and the heat sinks are easy to manufacture and transfer heat more effectively.

Abstract:
A solar lighting device includes a transparent housing. Within the housing, there are provided a light-emitting member (e.g., LED or lamp), a control circuit having a microprocessor and a switch activated by magnetic force, light, or body temperature, and a solar battery for supplying electric power to both the light-emitting member and the control circuit. A transparent or translucent object such as cup, bottle, or ornament may be mounted on the lighting device such that light with varying color and/or brightness may be emitted from the object as controlled by the microprocessor and the switch activated by an approaching trigger member when the lighting device is activated.
Abstract:
A light-emitting diode (LED) device has a shade, an active heat-dissipation device and an LED module. The shade has a cavity. The active heat-dissipation device is mounted in the cavity in the shade and has a cooling board, an evaporator, a condenser, a compressor, an expansion valve and a refrigerant. The evaporator, condenser, compressor and expansion valve connect to each other to form a loop. The refrigerant is set in the loop.

Abstract:
An aquarium thermostat comprises a ventilation box and a transforming mechanism disposed in the ventilation box such that the transforming mechanism is regulated by a microcomputer control mechanism to effect the generation of heating or cooling energy by which the aquarium water flowing into the aquarium thermostat is heated or cooled to a present level. The heated or cooled water is then sent back to the interior of the aquarium via a pipe.
