Description of the Invention: [Technical Field] The present invention relates to a light-emitting diode fluorescent lamp, and more particularly to an improved structure of a light-emitting diode fluorescent tube. [Prior Art] Fluorescent tube is the most common type of lighting device. The fluorescent tube is filled with low-pressure argon or argon-helium mixed gas and mercury vapor, while the inner surface of the glass fluorescent tube is coated with a layer. Phosphorus fluorescent paint with filament coils made of tungsten at both ends of the tube. When the power is turned on, first, the current is heated through the filament to release the electrons. The electrons will turn the gas in the tube into a plasma, and the current in the tube will increase. When the voltage between the two sets of filaments exceeds a certain value, the tube will start to discharge. Mercury; Thai gas emits ultraviolet light at 253.7nm and 185nm wavelength, and the phosphorescent paint on the inner surface of the fluorescent tube absorbs ultraviolet light and emits lower wavelength visible light. The color of the emitted light is controlled by the proportion of the lining component, while the glass tube prevents harmful UV rays and other harmful substances such as mercury 9 from leaking out. The general glory tube is made of glass, and it is equipped with fine (four) connection and fixed light pipe:: Because the mercury vapor itself has the defect of polluting the environment, the white light emitting diode has replaced the fluorescent lamp. For the sake of the atmosphere. Because of the fluorescent tube of glass material, it is gradually reduced to the pole of plastic material. I* — ^°"hereinafter referred to as LED), which is also a white light emitting diode. Three kinds: the first LED (near-UV, the wavelength is ^ 疋 监 尤 尤 为 为 为 为 为 为 上 上 上 上 上 上 上 2009 2009 2009 2009 2009 2009 2009 2009 2009 2009 2009 2009 2009 2009 2009 2009 2009 2009 2009 2009 2009 2009 2009 2009 2009 2009 2009 2009 2009 The ruthenium-aluminum-gallium (C e 3 +: YA G) crystal is ground into a powder and mixed in a dense binder. When the LED chip emits blue light, part of the blue light is converted into a broad spectrum of yellow light (the center of the spectrum is about 580 nm) by the fluorescent powder with great efficiency. Since yellow light stimulates the red and green receptors in the naked eye, the blue light of the LED itself is mixed to make it look like white light, and its color is often called "white of moonlight." Based on the characteristics of its spectrum, red and green objects appear to be less noticeable when illuminated by this type of LED. In addition, due to the instability of process quality, the color temperature of such LEDs is not uniform, from warm yellow to cool blue. The second type of white LED is made in a similar way to a fluorescent lamp. It is a mixture of two types of phosphor powder on a LED that emits near-ultraviolet light, one is a red and blue light, and the other is a green light. , noisy copper and zinc with zinc sulfide (ZnS). However, since the ultraviolet ray causes cracking and deterioration of the epoxy resin in the adhesive, the production is difficult and the life is short. Compared with the first LED, it works less efficiently and generates more waste heat, but has the advantage that the spectral characteristics are better. In addition, because the LED power of the ultraviolet light is higher, the efficiency is lower than that of the first type of LED, and the brightness is similar. White fluorescent powder based on YAG and TAG has been monopolized by the patents of some big manufacturers. The third method of manufacturing white LEDs no longer uses fluorescent powder, but instead grows stupid magnetized zinc on zinc-coated zinc (ZnSe) substrate. Crystal layer. When energized, the conduction band of the epitaxial layer emits blue light and the substrate glows yellow, which is white light when mixed. 6 200930939 There are two difficulties that must be overcome when Zhaoyi's 1 Bu Μ White S LED replaces the traditional fluorescent fluorescent lamp for use as ... for the month. First, the white light led is a directional point light source. When a plurality of white LEDs are used instead of the traditional "light", the brightness of the light cannot be uniformly emitted like a conventional fluorescent neon, and is easily formed on the illuminated object. The aperture of multiple overlapping shadows. ^2, white LED itself has a very serious problem of light decay; light decay 'mainly, caused by three factors: The first is that the LED emission efficiency decreases with the increase of temperature, the first Second, the conversion efficiency of the phosphor powder decreases with increasing temperature. The second is that the transmittance of the encapsulating resin is lowered due to the deterioration of the material caused by the temperature. In view of the problems of the conventional techniques, in order to solve the problem Based on years of research and development and many practical experiences, the inventors have proposed an improved type of branch building as an implementation and basis for improving the above disadvantages. [Inventive content] In view of the above, the object of the present invention is to provide a comparison. The light-emitting diode fluorescent tube of Jia design is used as the cornerstone of the fluorescent lamp as the light-emitting diode fluorescent lamp. The edge is 'the light-emitting diode solar light according to the invention for the above purpose The tube comprises a tube body, an atomization area, a first trench and a second trench. The tube system is for accommodating a circuit board, and the circuit board carries a plurality of light emitting diodes and related circuits. The region is located on the surface of the tube body for scattering the directional light emitted by the plurality of light-emitting diodes to achieve uniformity of brightness. The first trench 200930939 is located in one of the inner walls of the tube. The first side, the second groove is located on a first side of the inner wall of the tube, and the first side corresponds to the second side, wherein the first groove is for receiving the first side of the circuit board, and the second The trench is for receiving the first side of the circuit board, whereby the circuit board can be fixed to the inside of the pipe body through the first groove and the second groove without being shaken with an external force to be displaced. The atomization region may be located on the lower surface of the tube body; thereby, the light-emitting diode fluorescent tube of the present invention can simultaneously have the function of indicating the polarity direction of the power source of the light-emitting diode lamp. In other words, due to the conventional fluorescent lamp There is no power polarity problem, so when installing It is necessary to distinguish between the upper and lower parts, but the light-emitting diode fluorescent lamp has the problem of the polarity of the power supply. Therefore, it is necessary to distinguish the upper and lower sides so as to prevent the polarity from being reversely inserted, resulting in failure to work or even damage the circuit or the light-emitting diode. Therefore, the fog located on the lower surface of the pipe body The area is more atomized or completely transparent than the tube, which makes the user easy to distinguish without reversed to improve the identification. According to the invention, the luminous diode of the invention is characterized by the invention. There are two grooves in the inner wall of the tube to accommodate the circuit board, thereby fixing the position of the circuit board, and the atomizing surface of the tube is scattered to reflect the directional light, so that the tube emits non-directional light. In addition, the semi-atomized area on the lower surface of the tube also helps to identify the polar direction of the LED backlight. In order to give your reviewers a better understanding of the technical features and effects of the present invention. And the understanding of 'the best examples and the detailed descriptions are as follows. 8 200930939 [Embodiment] Hereinafter, a light-emitting diode fluorescent tube according to a preferred embodiment of the present invention will be described with reference to the accompanying drawings. For ease of understanding, the same components in the following embodiments are denoted by the same reference numerals. . Please refer to Fig. 1, which is a schematic structural view of a light-emitting diode fluorescent tube of the present invention. In the drawings, the present invention comprises a tube body 1 , an atomization region 30 , a first trench 31 and a second trench 32 . The tubular body 1 is for accommodating a circuit board 20, and the circuit board 2 承载 carries a plurality of light-emitting diodes 21 and their associated circuits 22. The atomization region 30 is located on the surface of the tube body 1 , to scatter the directional light source emitted by the plurality of light-emitting diodes 21 to achieve uniformity of brightness. The first groove 31 is located on a first side of the inner wall of the tubular body ίο, for example, the left side, and the second groove 32 is located on a second side of the inner wall of the tubular body 10, for example, the right side. The first trench 31 is for receiving the first side of the circuit board 20, and the second trench is for receiving the second side of the circuit board 2G. Thereby, the circuit board 2 can be fixed to the inside of the (4) 1G through the first groove 31 and the second groove 32 without being shaken with an external force, so as to be displaced. Therefore, the first groove 31 and the = groove 32 are preferably located at both ends of a diameter inside the pipe body 1〇. Thereby, the trench 31 and the second trench 32 can accommodate a rectangular plate, that is, the electrical circuit: the circuit board 2. It will be fixed in the tube body, without the external force production, "a plurality of white light-emitting diodes 21"; when there is directional light, the atomizing surface 30 will be irregular, change some The direction of travel of the directional light is then transmitted outside the tube body 9 200930939 10 to emit light having no directivity. Thereby, the light-emitting diode fluorescent tube of the present invention solves the point light source of the white light-emitting diode of the known light Problems of glare caused by characteristics and uneven distribution of brightness. Moreover, due to the light provided by each of the white light-emitting diodes 21, a redistribution effect is generated in the atomization region 30; therefore, the present invention, the diode The fluorescent tube can also slow down the effect of the light decay of the white light-emitting diode 21. In other words, when the light-emitting diode fluorescent tube has a self-lighting illuminator = _21 produces light decay, 'because the light is in the (10) 匕 area - again Therefore, the side that generates the light decay can be compensated, so that the effect of improving the light decay is visually improved by the naked eye. Referring to FIG. 2, it is a light-emitting diode fluorescent tube of the present invention, for example, In the embodiment, a left and right groove, that is, a first groove 31 and a second groove 32 are disposed in a tube 10 formed of a glass, a plastic, an acryl or a polymer. The first groove 叮 and the second groove 32 are formed in such a manner that two ridges are formed on the inner wall of the pipe body 1 (the protrusions are separated by a small distance), and the gap between the two protrusions is That is, 2 is for accommodating the above-mentioned circuit board 20; further, the two protrusions can also be fitted to the circuit board 20 one by one, thereby preventing the circuit board 2 from being displaced by the external force in the tube body 1〇. Referring to Fig. 3, there is shown a cross-sectional view of another embodiment of a light-emitting diode fluorescent tube of the present invention. This embodiment is a tube body made of glass, plastic, crepe or high molecular polymer. The two trenches, that is, the first trench 33 and the second trench 34 are cut in. The rectangular plate-shaped circuit board 20 can be accommodated in the first trench 33 and the second trench 34. , 200930939 The first groove 33 is located on the left side of the inner wall of the pipe body 20 to accommodate the left side of the circuit board 2 ,, and the second groove 34 is located on the right side of the inner wall of the pipe body 2 以 to accommodate The right side 20 of the plate.

In the present embodiment, the tube body 1 is used to cover the circuit board 20, and the circuit board 20 carries a plurality of white light emitting diodes 21 and associated circuits 22. Thereby, the light-emitting diode daylight of the embodiment can be matched with the size of a conventional lamp holder. If the material of the tube body 1 is glass, the present embodiment can manufacture the atomization region 35 by means of foaming, incorporation into glass fibers, grinding or even affixing an optical film. If the material of the tubular body 1 is plastic, the method of manufacturing the atomized region 35 may preferably be physical grinding or die biting. In the figure, a semi-atomization region 35 and a transparent region 36 are disposed on the tube body 1 of the present embodiment. Among them, the semi-atomization area % is preferably distributed on the lower half of the tube body 10, that is, the side for illumination. It is well known that, based on the theory of power transmission, the general commercial power is high-voltage alternating current, and the light-emitting diode 21 can only produce a photoelectric effect when it is biased in the forward direction of low-voltage direct current or alternating current. Therefore, when the conventional fluorescent lamp is replaced by the white light emitting diode 21, it is preferable to convert the commercial power into a low voltage direct current using a rectifying and transforming device. Moreover, since the conventional lamp holder itself has only two lamp legs to provide alternating current; therefore, when a white light emitting diode fluorescent lamp is used, the two lamp legs which are not directional are required to be transformed into a directional positive and negative electrode. At this time, if the white light emitting diode fluorescent lamp itself has a protection mechanism, when the user mistakenly inserts the polarity of the white light emitting diode fluorescent lamp during installation, the white light emitting diode fluorescent lamp will not work normally; The light-emitting diode lamp itself has no protection mechanism. 11 200930939 The voltage polarity reverse insertion may damage the light-emitting diode 21 and even cause danger. Thus, the semi-atomized region 35 on the tubular body 10, in this embodiment, can be used as an obvious sign of the identification polarity in addition to achieving average light intensity and slowing down light decay. In other words, the user can ensure that the polarity of the white light emitting diode lamp is broken when the semi-atomizing region 35 on the tube 10 is turned downward. In addition, in the actual production process, since the semi-atomization region 12 is only located on the lower surface of the pipe body 10; that is, the upper surface of the pipe body 1 can still be a plastic, acrylic or glass containing the transparent region 36. . Therefore, on the production line, the transparent upper surface of the tube ΐθ can be easily observed to observe whether the plurality of white light-emitting diodes 电路 on the circuit board 2 and the associated circuit 22 are assembled correctly β, that is, only in the tube body 忉The semi-atomization area % I of the lower surface is more capable of checking the authenticity of the assembly in the production process than the atomization area 30 shown in Fig. 1, thereby improving the quality level of the product. Referring to Figures 5 and 6, it is a schematic structural view of another embodiment of the fluorescent lamp of the present invention and a schematic structural view of the side cover. In the present embodiment, the conventional fluorescent lamp tube is sealed with an aluminum cap to seal the openings on both sides of the glass tube, and two columnar lamp legs are formed on the aluminum cap; therefore, in order to conform to the size of the conventional lamp holder With the specification design, the light-emitting diode fluorescent tube of the present embodiment replaces the conventional aluminum cap with a side cover 5, as shown in FIG. 6, the material of the side cover 50 may be a cork or a soft plastic material. In order to make the side cover 5〇 tightly coupled with the tubular body, the tubular body 10 of the present embodiment can be opened with a plurality of openings near the ends, as shown by the first opening 41 and the second opening 42. On the side cover 5, a plurality of double-angle bumps 51 may be disposed. Thereby, the triangular projection 51 can be engaged with the first opening 41 12 200930939 or the second opening 42 without being loosened.
