Disclosed is a method for manufacturing white light-emitting diodes (white LEDs) which is capable of manufacturing white LEDs having a superior and uniform quality and a slim structure while simplifying the manufacturing process, thereby reducing the manufacturing costs and time, and achieving a considerable improvement in the yield of those white LEDs. The method involves the steps of mixing a fluorescent dye, adapted to convert blue light into white light, with molding compound powder, thereby preparing a mixture, subjecting the mixture to a desired temperature and a desired pressure, thereby shaping the mixture to have a desired shape, simultaneously transfer-molding the shaped mixture on the blue-light emitting diode chips, thereby forming a molded product, and dicing the molded product into individual white LEDs. Since the method of the present invention eliminates use of a potting process used in conventional methods, it can manufacture white LEDs having a slim structure. In accordance with the method of the present invention, the manufacturing process is simplified, thereby reducing the manufacturing costs and time. Also, it is possible to achieve a considerable improvement in the yield of white LEDs having a superior and uniform quality.

The present invention relates to a method for controlling the operation of a compressor for preventing noise that occurs in case of the shortage of refrigerant flow caused by less discharge capacity of the compressor of an air conditioner for a vehicle. In a method for controlling a compressor of an air conditioner for a vehicle according to the present invention, wherein the compressor includes a cylinder bore 13 for compressing a refrigerant, a piston 15 inserted into the cylinder bore 13, a swash plate 48 having a controllable slope with respect to a drive shaft 40, and a control valve 35 for controlling the slope of the swash plate 48, the discharge capacity of the compressor is increased if it is determined that vehicle speed and accelerating rate satisfy predetermined conditions. According to the present invention, a low flow rate state of refrigerant of the compressor is predicted, and then ECV duty is increased to prevent the compressor from entering the low flow rate state of refrigerant, thereby improving the workability of the compressor and solving noise problem.

A car defogging system reduces energy required to defog a windshield glass of the car. A temperature sensor mounted at the windshield glass detects the glass surface temperature, Ts. A humidity sensor spaced from the windshield glass by a predetermined distance detects the humidity, H, around the windshield glass. A temperature sensor mounted inside the windshield glass detects peripheral temperature Te around the glass. A system controller determines if fog is or is not present by comparing the dew point temperature Td with the surface temperature Ts. Dew point temperature Td is derived by the combining values of H and a temperature Tc based on a combination of Ts and Te.
摘要:
A thermoelectric refrigerator/warmer using no external power, and a refrigerating/warming method are disclosed. A natural energy such as the solar energy is utilized so as to make an external power needless. Thus a thermoelectric device is made to convert the natural energy into electric power based on the difference between the internal and external temperatures, and this electric energy is converted again into a thermal energy by means of a peltier device, thereby varying the internal temperature of the apparatus. An outer part 4 of a thermoelectric device 3 is attached on the side face of the refrigerator/warmer, and an inner part 5 of it is attached on a bottom plate 7 of the refrigerator/warmer. Thus a thermoelectromotive force is generated based on the temperature difference between outside and inside of the refrigerator/warmer. The voltage thus generated is supplied to a peltier device 6 to cool or heat the bottom plate 7. In this manner, the thermoelectric refrigerator/warmer can be operated even without using an external power.
