Problems solved by technology
For example, traditionally, at least three control systems must be used to control the variable colors of rare gas discharge lamps with three light colors: red, green and blue, which complicates the original structure of the light source and increases the production cost.

Embodiment Construction
[0023] The color-changing discharge lamp device described in the embodiment of the present invention includes at least two lamp tubes connected together. The luminous efficiency of the LED will be affected by the change of the voltage, thus producing a variety of mixed light colors. A plurality of structures are described below, but the scope of the present invention is not limited.
[0024] Please refer to figure 1 , which is a schematic diagram of a color-changing discharge lamp device according to a preferred embodiment of the present invention. The variable color discharge lamp device 100 includes a first lamp tube 101, a second lamp tube 103, a third lamp tube 105 and a variable voltage system 110, wherein the first lamp tube 101, the second lamp tube 103 and the first lamp tube 103 The three lamp tubes 105 are connected together so that the insides of the three lamp tubes communicate with each other to form a single lamp, and are connected to the variable voltage syste...

The invention discloses a variable color discharge lamp device, which comprises a first tube, a second tube and a variable voltage system. The first tube comprises a first caliber, wherein first fluorescent powder is arranged in the first tube; the second tube is connected with the first tube and comprises a second caliber, wherein the second caliber is different from the first caliber; second fluorescent powder is arranged in the second tube, wherein a second color temperature of the second fluorescent powder is different from a first color temperature of the first fluorescent powder; the variable voltage system is connected with the first tube and the second tube and used for providing and regulating and controlling a common voltage of the first tube and the second tube; and when the common voltage is regulated, the respective luminous efficiencies of the first fluorescent powder and the second fluorescent powder change along with the common voltage so as to adjust the mixed color of the first tube and the second tube.
Description
technical field [0001] The present invention relates to a discharge lamp device, and in particular to a variable color discharge lamp device. Background technique [0002] There are several kinds of light sources that are indispensable in daily life, such as: incandescent lamps, fluorescent lamps, high-pressure gas discharge lamps, etc. Since the photoelectric conversion efficiency of incandescent lamps is extremely poor (only about 10% will be converted into light) and will generate high temperature, in comparison, the conversion efficiency of fluorescent lamps is much higher (close to 40%). In addition, the heat generated by fluorescent lamps is only one-sixth of that of incandescent lamps with the same brightness, making incandescent lamps generally replaced by fluorescent lamps in many occasions. For example, fluorescent lighting is used to save electricity in shopping malls, stores, and office buildings that require air conditioning. Compact fluorescent lamps, or ener...
