Description of the invention: 'Technical field to which the invention pertains>> The present invention relates to a lamp for lighting, and more particularly to a three-wavelength LED white light tube structure that is easy to adjust color temperature. [Prior Art] According to the fact that Light Emitting Diode (LED) has low energy consumption and high efficiency, it is now a key technology for strategy development in various countries and industries. To replace the existing traditional lighting equipment. As shown in the first figure, the existing LED lighting tube is characterized in that a plurality of red, green and blue LED elements 1, 2, 3 are electrically connected to a circuit board 4, and then connected by the circuit board 4. A connection terminal (not shown) is electrically connected to the power source (or the socket) by the connection terminal, so that the three primary colors of light (red, green, and blue) can be used to illuminate the white light for illumination. However, this method uses red, green, and blue light to mix white light. In addition to the wavelength matching, it is necessary to have a white color. The light intensity must also have an appropriate ratio. Therefore, it is quite difficult to implement the light mixing. Common white light. It only appears in the center of the intersection of the beams. The color temperature of the mixed light away from the central area will gradually approach the red, green and 原 primary colors, forming a mixed color block in the illumination area, which is caused by the uneven mixing and illumination. not effectively. Please refer to the two figures. Another LED lighting tube is to electrically connect most of the four red, green and blue LED components 1, 2, and 3 to the circuit board 4 of 201028592, and then the circuit. The board 4 is connected to a connection terminal (not shown) and a transparent lamp cover 5 is disposed in front of the circuit board 4. The inside of the transparent lamp cover 5 is filled with phosphor powder 6 to utilize the three primary colors of light (red, Green, blue) mixed with white light for illumination through the mixing of phosphor powder. However, the illumination angle of this method is limited, and the LED elements 1, 2, and 3 are accompanied by high heat, and the phosphor powder 6 itself is not resistant to high temperature, so when the temperature of the LED element is increased, the phosphor powder It will quickly produce a qualitative change, causing the LED component to produce light decay, which seriously affects the illumination or brightness. Secondly, the wavelength of the LED depends on the structure and composition of the epitaxial layer, and more importantly, the problem of lattice matching, which causes the semiconductor to drift due to the high temperature and low wavelength. In the initial stage of power-on and power-on for a period of time, with the intensity of red light-emitting efficiency at the beginning of the booting, the rGB three primary colors of light mix out a white reddish light source; after a period of power-on, the blue light with higher luminous efficiency is gradually enhanced. The color temperature is biased toward the white light of the cold light system, so the color temperature of the light mixed in the two periods is different. According to the angle of the spectrum, the range of thermal drift from the warm color to the cool color is too large, which seriously affects the white balance of the mixed color temperature and relatively reduces the illumination of the light source. In addition, there is also a LED that uses a white light as the main light source, and a set of color temperature compensation units composed of red, green, blue light and the like are arranged near the white LED, that is, when the brightness of the white LED is changed rapidly due to the quality of the fluorescent layer. When the light decays, the red, green, and blue LEDs are adjusted with the current intensity of the single or multiple white LEDs. However, this method can not only accurately restore the original color temperature of the original white light, and it is difficult to control the current intensity of the single 5 201028592 or more, which is actually quite difficult and economical. SUMMARY OF THE INVENTION In view of the above, the main object of the present invention is to provide a three-wavelength LED white light tube structure that is easy to adjust the color temperature, which can reduce the unevenness of light mixing, and to make the white light effect of illumination better. Another main object of the present invention is to provide a β-three-wavelength LED white light tube structure which is easy to adjust the color temperature, and can adjust the color temperature between cool white light and warm white light. Still another main object of the present invention is to provide a three-wavelength LED white light tube structure which is easy to adjust the color temperature, and which is capable of forming a high color rendering three-wavelength white light.
