  • Electroluminescent clock
    Patent number: 6811278
    Abstract: An electroluminescent clock is disclosed, wherein light emitting dots are installed on the back side of a transparent plate and ring around and beneath luminous markers, whereby when the light emitting dots are enabled, the luminous markers can be presented with uniform lighting to allow a user to see the clock time in the darkness and even from a distance. The night light feature is further enhanced by a special design that creates a soft visual effect on the dial of the clock for easy recognition of clock time.

  • Clock with luminous decoration
    Patent number: 6717889
    Abstract: A clock has a luminous decoration member provided on a dial of the clock. The luminous decoration member is made of a transparent material and formed in an annular shape having multiple lightings fitted therearound. A layer of fluorescent material is applied on a rear side of the luminous decoration member. Whereby when the lightings are providing light on the luminous decoration member, the fluorescent material applied on the luminous decoration member is lit so as to emit colorful fluorescence to the surroundings thereof. Therefore, a user can easily observe the dial and clock hands of the clock in the dark or night.
