  • Publication number: 20160238296
    Abstract: A cooling system includes a cooling device, a controller and a defrosting unit. The cooling device has a compressor, a condenser, an expander, an evaporator, a cooling channel and a coolant. The coolant is functioned in the evaporator to thermally exchange with a working fluid in a pipe. The controller is adapted for controlling the temperature of the working fluid by controlling the cooling device. The defrosting unit has a switch disposed on the cooling channel and located between the compressor and the condenser, and a defrosting channel connected with the switch. After passing through the switch, the coolant is optionally fed to anyone of the cooling channel and the defrosting channel. After flowing through the defrosting channel, the coolant passes through the evaporator and then flows back to the compressor. As a result, the cooling system is capable of fast defrosting without using a heater.

  • Patent number: 9377214
    Abstract: A heating device includes a housing having a flow channel, a heater disposed in the flow channel, an optical rod, a light guider and a photodetector. The optical rod has a transparent body, a first end portion, and a second end portion located inside the housing. The light guider is provided at the second end portion for guiding lights emitted by the heater toward the first end portion. The photodetector is located around the first end portion and faces the second end portion for indirectly receiving the lights emitted by the heater to the light guider through the transparent body. The temperature of the heater can be measured efficiently and timely by using the photodetector having a high responding speed, such that an overheat or damage of the heater can be prevented by controlling the heater based on the measured temperature.

  • Patent number: 9232600
    Abstract: A light-emitting module and a driving method thereof are disclosed. In this method, P light-emitting units are selected as a target group, wherein each of the P light-emitting units has N different power parameters corresponding to N sub-bands. P evaluated current values corresponding to the P light-emitting units are computed according to a target spectrum and the N×P power parameters corresponding to the P light-emitting unit in the target group. An emission-spectrum error is computed according to the target spectrum, the N×P power parameters, and the P evaluated current values. It is determined whether the emission-spectrum error conforms with the determining criteria. When the emission-spectrum error conforms with determining criteria, the P evaluated current values are set to be P driving current values corresponding to the P light-emitting units.
