  • Light emitting device with tension relaxation
    Patent number: 8044421
    Abstract: A light emitting device is provided, comprising a light emitting diode 10, where the light emitting surface 11 thereof is bound to an optical element 13 by means of a bonding material 12 comprising a phosphate glass or an oxide glass having Tg<250° C. In operation of the device, when the temperature approaches or exceeds Tg of the bonding material, the bonding material gets fluidic and can thus relax any thermally induced stresses between the light emitting diode and the optical element.
    Type: Grant

  • Steam iron having a hydrophilic acid resistant steam changer
    Patent number: 5060406
    Abstract: A steam iron having an acid-resistant, hydrophilic coating in the steam chamber. The steam chamber coating is provided from an acid, colloidal suspension comprising alumina, magnesia, silica, or mixtures thereof, and contains, preferably, an acid phosphate compound. In this case, particularly Al(H.sub.2 PO.sub.4).sub.3 is very suitable. The steam chamber coating is very corrosion-resistant.
