Definitions

  • the present invention relates to a lighting lamp capable of adjusting brightness and color of light, and more particularly, to a lighting lamp that can diversely adjust brightness and color of light in combination in accordance with a user's taste or a used state of the lamp.
  • a lighting lamp used in the home or office is monochromatic and has a constant brightness or color temperature.
  • RGB three-wave
  • the users' tastes in color and brightness of light are slightly different from one another.
  • the proper brightness in the morning, afternoon, and evening are 4000K, 6000K, and 3000K, respectively, it is necessary to automatically or manually adjust the brightness of the lighting lamp, but the conventional lighting lamp cannot realize such adjustment.
  • United States Patent No. 5,384, 519 discloses a method of mixing respective colors in the lighting lamp, which forms respective single-wave tubes by applying three color elements of red (R), green (G), and blue (B) and a white color (W), and adjusts a desired brightness and color of light by adjusting outputs of tubes of R, G, B, and W.
  • the present invention is directed to a lighting lamp capable of adjusting brightness and color of light that substantially obviates one or more problems due to limitations and disadvantages of the related art.
  • a lighting lamp including two or more lamps having different luminous colors, an external power supply, a rectifying section, a stabilizing section, and an adjustment section for lighting the respective lamps, so that color and brightness of a light source are adjusted by manipulation of the adjustment section, the lighting lamp comprising a lamp section composed of a pair of different color temperature tubes having multiwaves by mixing three or more fluorescent powders to change the brightness and the color.
  • one of the color temperature tubes having a Kelvin temperature in the range of about 1,600 ⁇ 2,700 °K and the other of the color temperature tubes having a Kelvin temperature in the range of about 5,000 ⁇ 10,000 °K and a manipulation section composed of a display for displaying an adjustment state of the brightness and the color of the lamp within a predetermined range, and an adjustment switch for adjusting the brightness and the color within the predetermined range.
  • FIG. 1 is a schematic block diagram illustrating the construction of a lighting lamp capable of adjusting brightness and color according to the present invention.
  • the lighting lamp according to the present invention includes a pair of different color temperature tubes having multiwaves by mixing three (for example, R, G, and B) or more fluorescent powders to change the brightness and the color.
  • One of the color temperature tubes has a Kelvin temperature in the range of about 1,600 ⁇ 2,700 °K. and the other of the color temperature tubes has a Kelvin temperature in the range of about 5,000 ⁇ 10,000 °K.
  • the different color temperature tubes (or a lamp section) 30 operate by an external power supply AC, and the power supply is connected to provide a bias power supply to a rectifying section 10, a stabilizing section 20, and an adjustment section 40.
  • the lighting lamp capable of adjusting brightness and color may be constructed as follows in accordance with its installation state.
  • Stabilizers in the stabilizing section 20, which are connected to the tubes 30 having the different Kelvin temperatures, respectively, are also connected to the manipulation section 40 for controlling outputs of the stabilizing section 20 as shown in the drawing.
  • the respective stabilizers may be controlled individually or in combination, or may have diverse types in accordance with an automatic operation in a predetermined manipulation range or a manual operation.
  • the color and the brightness of the lamp can be adjusted to be most suitable for study in addition to the basic turn-on/off operation of the lamp by manipulation of a plurality of buttons for adjusting the brightness and the color.
  • the manipulation section 40 for adjusting the brightness and the color of the lighting lamp is provided with a display section 42 and a plurality of adjustment buttons.
  • the buttons are for adjusting the brightness and the color of the lamps 30, for example, for adjusting the color of the light to a high color temperature (i.e., the color of the sunrise) or to a low color temperature (i.e., the color of the sunset), and/or adjusting the brightness of the light to a bright light or a dark light.
  • the display section 42 includes light-emitting diodes (LEDs) for indicating the adjustment grade of the brightness and the color on X/Y axes as shown in FIG. 2.
  • the manipulation section 40 enables the adjustment within the predetermined brightness and color ranges. For instance, in a high color temperature region, it makes an alpha wave (in the range of 8 ⁇ 12Hz) be generated, while in a low color temperature region, it makes a theta wave (in the range of 4 ⁇ 7Hz) be produced. Also, in a bright region, it makes a beta wave (in the range of 13 ⁇ 30Hz) be produced, while in a dark region, it makes a delta wave (in the range of 1 ⁇ 3Hz) be produced. In consequence, it heightens the brightness and the color of the lamp during the study that requires a logical thinking (See FIG. 3A), while it lowers the brightness and the color of the lamp during the study that requires an emotional thinking, thereby improving the efficiency of the study (See FIG. 3B).
  • the adjustment buttons in the manipulation section for adjusting the brightness and the color of the lighting lamp may have diverse forms such as slide switches, joysticks. etc.
  • the lighting lamp can produce optimum illumination effects by diversely adjusting the brightness and the color of light in accordance with the purpose of use of general desk lamps, lighting fixtures, exhibition lamps, etc.
  • the present invention has the advantage that it can automatically or manually adjust brightness and color of light in accordance with a used state and purpose of a lighting lamp by employing different color temperature tubes mixed with three or more fluorescent powders to change the brightness and the color of the lamp.
