It is a new type of light source in the 21st century, which has the advantages of high efficiency, long life, and is not easily damaged. When a forward voltage is applied, the light-emitting diode emits a single, discontinuous light, which is one of the electroluminescence effects. By changing the chemical composition of the semiconductor material used, the light-emitting diode can emit light in the near ultraviolet, visible or infrared light. However, the specifications of the Xenon tube have been extended for many years; the reason is that in order to meet the needs of the surrounding industries of the Xenon tube, there is an introduction of the LED lamp. Although the light-emitting diode lamp has the advantages of the light-emitting diode for illumination, if the light-emitting diode is simply placed in the general light-transmitting tube, the light-emitting diode itself is a point light source. There are problems such as glare or uneven illumination distribution.

The substrate is disposed in the light-transmitting tube body to carry a plurality of light-emitting diodes, and the distance between the light-emitting diodes and the light-transmitting tube body is Η, and the distance between each two of the light-emitting diodes is ρ; /p is not less than 0.134, and Η is 9.5~38mm. The surface of the heat sink is bonded to the substrate to help dissipate heat from the LED. In addition, in other embodiments of the present technical aspect, the light-transmitting tube body may be a φ-glass tube having a length of 200 to 1500 mm, and further includes two covers respectively disposed at opposite ends of the light-transmitting tube body to seal the substrate. In the light-transmitting tube body. On the other hand, in an embodiment, the space sealed by the transparent tube and the two covers may be evacuated, or an inert gas such as helium or argon may be added. In order to block water gas, oxygen and other gas substances that endanger the products in the pipe. In the use of the phosphor powder, the disclosure may be in an embodiment, the particle size of the phosphor particles is a dime, and the particle size is smaller than the thickness of the phosphor layer, especially the inside of the phosphor layer. The particle size of the phosphor powder particles 10 can be further controlled at 5 to 2 〇 / / m. It is worth noting that the excitation light layer excitation wavelength is 300 ~ 5 〇〇 nm, and the emission wavelength is _ ~ 7 〇〇 leg And the illuminating-polar wavelength, 3GG~7GGnm, and the light-emitting angle thereof can be used in the implementation of the square gas with a maximum light-emitting angle of ~14G degrees; of course, the light-emitting angle can also be designed to be 110-180 degrees. In this way, the light-emitting diode lighting tube of the above embodiments can provide illumination white light and achieve both illumination and uniformity. [Embodiment] 5 M413802 July 14, 2011 correction replacement page, please refer to FIG. 1 is a schematic structural view of a light-emitting diode lighting tube according to an embodiment of the present disclosure. In FIG. 1 , the light-emitting diode lighting tube 100 includes a light-transmitting tube body 11 and a phosphor powder layer 12〇. , a substrate 130 and a heat sink 15 〇β phosphor layer 12〇 coating The thickness of the phosphor layer 120 is 1〇~1〇〇. The substrate 130 is disposed in the transparent tube body 110 to carry the plurality of light emitting diodes 131. The light emitting diode of the embodiment The body light tube 1 is used to provide an illumination source; for example, the light-emitting diode 131 can emit blue light, and the phosphor layer 12 can be • yellow phosphor powder. The surface of the heat sink 150 is bonded to the substrate. 130, to help the heat-dissipating body 131 to dissipate heat. For example, the heat-dissipating plate 150 can be attached to the substrate 130' at the bonding surface and can also be coated with a heat-dissipating paste, and the heat-dissipating plate 15 can be provided with a heat-dissipating body for increasing the surface area. 151, for example, heat sink fins. Please refer to FIG. 2'. FIG. 2 is a cross-sectional view of the light-emitting diode lighting tube 100 of FIG. 1. For convenience of explanation, a power supply 200' power supply is further illustrated in FIG. 200 is electrically connected to the substrate 13A to provide power to the light-emitting diode 131. The light-transmitting tube body 11 () may be a glass tube having a length of 200 to 1500 mm; for example, the main component of the glass tube is 矽It can be mixed with components such as potassium, sodium, and side. On the other hand, the light-transmitting tube body 110 The two cover covers 140' are respectively located at two ends of the transparent tube body 11 () to seal the substrate 13 in the transparent tube body 110. Of course, in one embodiment of the present disclosure, The space sealed by the light pipe body 110 and the two covers 140 can be vacuumed or filled with an inert gas, such as an argon or helium gas, to block moisture, oxygen, and the like, which are harmful to the products in the pipe, thereby achieving moisture resistance. In the use of camping powder, the particle size of the phosphor powder 121 is “Bai Xian” 6 M413802 • The date of July 2011 is revised to the page m′ and the particle size is smaller than the thickness of the phosphor layer 120; in particular, the firefly The particle size of the phosphor particles 121 inside the toner layer can be further controlled to 5 to 2 μm. For example, the phosphor powder layer 120 adopts a film thickness of 3 〇am to match the fluorescein powder particle 121 with a 10"m particle size phosphor powder. Furthermore, the excitation light layer has an excitation wavelength of 300 to 500 nm, an emission wavelength of 4 〇〇 to 7 〇〇 nm, and a light-emitting diode wavelength of 300 to 700 nm. In the method, the phosphor layer 120 is applied to the surface of the light-transmitting tube 110 by a normal temperature process using water or a solvent at a normal temperature. For example, the use of a water-emitting diode lamp 1 manufactured by a water coating method at room temperature has the advantage of being easy to process and quick to manufacture. Moreover, the light generated by the light-emitting diode 131 is reflected and reflected in the light-transmitting tube body 11 多次, and the light uniformity is excellent, and the illuminance is even higher than that of the general fluorescent tube. On the other hand, the substrate 130 carries the light-emitting diodes 13ι on the other side, and the heat-dissipating plate 150 is attached to the heat-dissipating plate 150 to prevent heat decay. The heat sink 15 has a thermal body 151 to improve heat dissipation efficiency. Please refer to FIG. 3 again. FIG. 3 is also a cross-sectional view of the light-emitting diode according to FIG. In the third embodiment, the substrate 130 can be formed on a heat dissipation plate 150. Generally, the heat dissipation plate 150, the substrate 130, and even the light-emitting diodes 131 fall on one of the transparent tubes 110, so that the light-emitting diodes 131 and The distance between the transparent tubes 110 in the light-emitting direction can be directly regarded as the diameter of the transparent tube body UG itself. Wherein, the heat dissipation plate 15G may be made of light metal or a heat dissipation pad, such as an aluminum fin plate; it is worth noting that if the heat sink 150 is used as the heat dissipation plate 150, the size of the heat dissipation plate 150 is approximately larger than the substrate 130; The pad is made as a heat sink 150, and the heat sink 150 can be as large as the substrate 130. 7 M413802 July 2011 U-day repair; Ε Ε replacement 寅 Please refer to Figure 4, and Figure 4 is a partial enlarged view of Figure 2. In Fig. 4, the distance between the light-emitting diode 131 and the light-transmitting tube body 110 is Η, and the distance between the two light-emitting diodes 131 is ρ; Η/ρ is not less than 0.134, and Η is 9.5. ~38mm. In other words, Η is almost equivalent to the diameter of the light-transmitting pipe body 110 itself, and the transparent pipe body 110 can adopt a public standard such as Τ5, Τ8, Τ12, etc. The Η/Ρ ratio lower limit 0134 is calculated by the inventor of the present invention. as follows. Please refer to Fig. 5'. Fig. 5 is a schematic view showing the operation principle of the light-emitting diode illuminator φ tube 100 of Fig. 1. In Fig. 5, the light-emitting diode 131 can have an exit angle of I10~140', for example, a maximum light-emitting angle of 130 degrees; wherein the light-emitting angle refers to a limit of 50% reduction in illumination; of course, the light-emitting angle can also be designed. To the degree. According to the actual simulation in Fig. 5, the intensity of the beam light provided by each of the light-emitting diodes 131 is attenuated with distance, and when the light intensity is only 60% ', that is, 3/5 10, both (1) The difference between 〇 and 3/5 1〇) will be recognized by the human eye. However, in the design of an embodiment of the present disclosure, the 30% illuminance φ 1 每 of each of the two light-emitting diodes 131 overlaps each other to reinforce the illuminance to 3/5 1 〇. When the blue light provided by the light-emitting diode 131 is superimposed and then reaches the phosphor powder layer 120 on the surface of the light-transmitting tube body 110, the bright spot can be removed to make the light source uniform. However, considering the ability of the human eye to identify, the inventor of this case has calculated through precision, and found that the ratio of Η/P must be no less than 0.134. For example, please refer to Fig. 6. Fig. 6 is a diagram showing the relationship between the light intensity/angle of view of the light-emitting diode 13A of Fig. 1. It can be seen from Fig. 6 that the light intensity of the single light-emitting diode 131 varies with angle, and it can be observed that the light intensity of 3/1 〇 〇 约 is about 75 degrees. In other words, if the two-phase illuminating diode 8 M413802 is fixed at the intersection of the difficult page 131 on July 14, 2011, and falls at the respective 3 Π 0 1 〇 light intensity, then the two phases can be reinforced. The lower limit of eye visual brightness recognition ability, that is, 6〇% total illumination is 1〇. Please refer to Fig. 7, which is a schematic diagram of the exit angle limit of the light-emitting diode 131 of Fig. 6. When the light-emitting angle is 130 degrees, the light intensity provided by the light-emitting diode 131 (LED) can reach the surface of the light-transmitting body 110 uniformly, that is, the phase two adjacent light-emitting diodes 31 are at the light junction. Each of the 3/1〇10 intensity lights is reinforced with a light intensity of 3/51 inch, which is connected to the boundary line recognized by the φ human eye. The distance between each of the light-emitting diodes 131 and the light-emitting diode is 131. The height distance H of the light pipe body 11 must satisfy the following formula: -^ = tan 15° =0.268 Η => gt; = 0.134 to limit the volume == to expose the above - but it is not used by ordinary people, no Revealing the technical field
