New description: [New technical field] [0001] The present invention relates to a light-emitting diode light bar, and more particularly to a light-emitting diode light bar with uniform light intensity. [Prior Art] [0002] A Light Emitting Diode (LED) is a semiconductor element that converts a current into light of a specific wavelength range. The light-emitting diode is widely used in the field of illumination because of its high brightness, low operating voltage, low power consumption, easy matching with integrated circuits, simple driving, and long life. [0003] A common application of light-emitting diodes is as a light-emitting diode strip. As shown in FIG. 1 , the LED strip 100 generally includes a long substrate 110 and a plurality of LED units 121 disposed on the substrate. The plurality of LED units 121 are along the length of the substrate. Arrange in the direction. In general, the plurality of light emitting diode units 121 are arranged at equal intervals. However, the light-emitting diode light bar 100 of this structure has a problem of uneven light intensity, that is, since the light intensity distribution in the light bar has a Fourier integral distribution, the light intensity in the middle of the light bar is greater than the light intensity at both ends. In addition, since the heat-dissipating distance of the light-emitting diode in the middle of the substrate is long, the heat energy generated by the light-emitting diode arranged in the middle of the substrate is not easily dissipated, causing the light bar to malfunction or reduce its life. [New content] [0004] In view of the above, it is necessary to provide a light-emitting diode light bar structure with uniform light emission. Form No. A0101 Page 4 of 20 M394409 [0005] A light-emitting diode light bar comprising an elongated substrate and a first light-emitting module and a second light-emitting module disposed on the elongated substrate . The first light emitting module is disposed at a middle portion of the substrate, and the second light emitting module is disposed at both ends of the substrate. The first light emitting module and the second light emitting module comprise a plurality of light emitting diode units, and the light emitting diode units are arranged at intervals along a length direction of the substrate. The arrangement density of the light emitting diode units increases from the middle of the substrate to both ends. [0006] Optionally, in the above-mentioned light-emitting diode light bar structure, the spacing between adjacent light-emitting diode units of the same light-emitting module t is the same. The arrangement of the light emitting diode units in the first light emitting module and the second light emitting module satisfies the following relationship: D1 > D2, wherein D1 is the spacing between adjacent light emitting diode units in the first light emitting module D2 is the spacing between adjacent light emitting diode units in the second light emitting module. 8毫米。 The value of D2 is about 8. 8mm. [0007] Optionally, the lighting module further includes a third lighting module. The third illuminating module is disposed between the first illuminating module and the second illuminating module, and the arrangement of the illuminating diode unit satisfies the following relationship: D1 > D3 > D2. Wherein D1 is the spacing between adjacent LED units in the first lighting module, D2 is the spacing between adjacent LED units in the second lighting module, and D3 is in the third lighting module. The spacing between adjacent light emitting diode elements. Optionally, the value of D1 is about 10.65 mm, the value of D2 is about 8.5 mm, and the value of D3 is about 9.7 5 mm. Optionally, the lighting module further includes a fourth lighting module. The fourth illuminating module is disposed between the first illuminating module and the third illuminating module, and the arrangement of the illuminating diode unit satisfies the following relationship: D1 > D3 > D4, wherein, the form number A0101 is 5 Page 20 M394409 D 4 is the spacing between adjacent light-emitting diode units in the fourth lighting module. [0009] Optionally, in the above-mentioned light-emitting diode light bar structure, a screw hole is disposed on the substrate, and the screw hole is disposed in an area between adjacent light-emitting modules to distinguish different light-emitting modules. And fixing screws, so that the light-emitting diode light bar can be disposed on a predetermined device. [ </ RTI> In the above-mentioned light-emitting diode strip structure, the substrate is formed by splicing a plurality of substrate units, and the light-emitting diode units arranged adjacent to each other and having the same pitch are disposed in the same substrate unit. [0011] Compared with the prior art, since the arrangement density of the light-emitting diode units in the middle of the substrate is smaller than the arrangement density of the two ends, the light-emitting intensity at the intermediate position of the substrate will be correspondingly smaller, and the light-emitting intensity at both ends will be correspondingly larger. Thereby, the entire LED strip has a relatively uniform light intensity distribution. In addition, since the arrangement density of the light-emitting diode units in the middle portion is small, it is less likely to cause heat to accumulate in the middle of the light bar, which affects the light-emitting performance of the light bar. [Embodiment] [0012] The present invention will be further described below with reference to specific embodiments. [0013] Referring to FIG. 2, a light-emitting diode light bar 200 according to a first embodiment of the present invention includes a long-shaped substrate 21A, a first light-emitting module 220 and a second light-emitting module disposed on the substrate 21A. Group 230. [0014] Referring to FIG. 3 together, the surface of the substrate 210 is provided with a conductive line (not shown). The substrate 210 may be a semiconductor substrate, a ceramic substrate, a metal substrate, or a printed circuit board. Preferably, the substrate 210 is an aluminum-based printed circuit board, which can effectively dissipate the heat generated by the first light-emitting module 220 and the second light-emitting module 230 during operation to the outside. A screw hole 240 is disposed on the substrate 21 〇 Form No. A0101, page 6 / 20 pages [0015], and the screw hole 240 is disposed between the first illuminating module 22 〇 and the second illuminating module 230 The area 'is used to distinguish different lighting modules and cooperate with screws (not shown) to fix the LED strips on a predetermined device. The first light emitting module 220 is disposed at a middle portion of the substrate 210. The first light-emitting module 220 includes a plurality of light-emitting diode units 221 which are arranged along the length direction of the substrate 210 to be & The LED unit 221 is a surface mount type device (SMD), and the electrode pins are electrically connected to an external electric source through a conductive line on the surface of the substrate 210 to be a light emitting diode unit. 22! Provide the corresponding drive voltage or drive two =. The light-emitting diode units 221 may be connected in series as needed: in parallel connection or in a hybrid connection. The threshold of the light-emitting diode 'body unit 21 is spaced. In the first light-emitting module 220, the spacing between adjacent hair-emitting cells 221 is the same, and the singulation is represented. In the present embodiment, the value of μ is about 10.3 mm. [0016] The second light emitting module 230 is disposed at both ends of the substrate 210. The first light-emitting assembly 220 and the second light-emitting module 23G may be connected or connected in parallel. The second light emitting module 230 includes a plurality of light emitting diode units 221 arranged in a row along the length direction of the substrate 210. Similarly, the plurality of light-emitting diode units 231 can be connected to each other in a series:: column, and can be connected in parallel, connected in parallel or connected in series. The spacing between adjacent light-emitting diode units 231 is the same, as used. The spacing between adjacent light emitting diode units 231 is smaller than the spacing between adjacent light emitting diode units 221 in the first light emitting module 220. 8毫米。 The value of D2 is about 8. 8mm. Form No. A0101 Page 7 / Total 20 pages M394409 [0017] Since the spacing between adjacent light emitting diode units 221 is larger than the spacing between adjacent light emitting diode units 231, the light emitting diodes in the middle of the substrate 210 are made. The arrangement density of the body cells is greater than the arrangement density of the light emitting diode cells at both ends of the substrate 210. That is, the light intensity at the center of the substrate 210 is lowered, and the light intensity at both ends of the substrate 210 is correspondingly increased. Therefore, the structure can avoid the phenomenon that the intermediate light-emitting intensity is high and the light-emitting intensity at both ends is low due to the equidistant arrangement of the light-emitting diode units, so that the entire light-emitting diode light strip 200 emits light uniformly. In addition, since the arrangement density of the LED unit 221 at the intermediate position of the substrate 210 is low, heat generated during the normal operation of the LED unit 221 can be prevented from accumulating in the middle position of the substrate 210, thereby causing lamp failure or service life. cut back. [0018] Referring to FIG. 4, the LED strip 300 of the second embodiment of the present invention includes a substrate 310 having a long shape, a first illuminating module 320 and a second illuminating module 330 disposed on the substrate 310. The first light emitting module 320 is disposed at a middle portion of the substrate 310, and the second light emitting module 330 is disposed at both ends of the substrate 310. The LED module 300 further includes a third lighting module 340 disposed between the first lighting module 320 and the second lighting module 330. [0019] The first light emitting module 320, the second light emitting module 330, and the third light emitting module 340 respectively include a plurality of light emitting diode units 321, a plurality of light emitting diode units 331 and a plurality of light emitting diode units. 341. Moreover, in the same light emitting module, the distance between adjacent two light emitting diode units is equal. The spacing of the adjacent light-emitting diode units 321 in the first light-emitting module 320 is represented by D1, and the spacing of the adjacent light-emitting diode units 331 in the second light-emitting module 330 is represented by D2, and the third light-emitting module 340 is in phase. Form number A0101 of the adjacent light-emitting diode unit 341 Page 8 of 20 M394409 The pitch is indicated by D3. The arrangement of the light-emitting diode units satisfies the following relationship, D1 > D3 > D2. In the present embodiment, the value of D1 is about 7.5 mm. The light-emitting diode lamp strip of the structure can also realize the lower arrangement density of the light-emitting diode unit in the middle part of the light bar, and the arrangement density of the light-emitting diode unit at both ends of the light bar is high, thereby The light intensity distribution of the entire LED strip 300 is made uniform. Screw holes may be provided in the area between adjacent two light-emitting modules of the substrate as needed to distinguish different light-emitting modules. [0020] Referring to FIG. 5, the LED light bar 400 of the third embodiment of the present invention includes a substrate 410 having a long shape, a first light emitting module 420 disposed on the substrate 410, and a second light emitting module 430. Three-shot first; module 440 and fourth lighting module 450. In this embodiment, the first light module 420 is disposed at a middle portion of the base plate 410. The second light emitting module 430 is disposed at both ends of the substrate 410. The third lighting module 440 is disposed between the first lighting module 420 and the second lighting module 430, and the fourth lighting module 450 is disposed between the first lighting module 420 and the third lighting module 440. The light emitting modules 420, 430, 440, and 450 respectively include a plurality of light emitting diode units 421, 431, 441, and 451. Moreover, the distance between adjacent two light emitting diode units in the same light emitting module is equal. The spacing between the light emitting diode units 421 is represented by D1, the spacing between the light emitting diode units 431 is represented by D2, and the spacing between the light emitting diode units 441 is represented by D3, and between the light emitting diode units 451. The spacing is indicated by D4. The light-emitting diode units are arranged along the length direction of the substrate 410, and the arrangement thereof satisfies the following relationship: D1 > D3 > D2 and D1 > D3 > D4. In this embodiment, since the spacing between the light emitting diode units 451 is smaller than the spacing between the light emitting diode units 441, the entire form number A0101 is 9 pages/20 pages of LED light strips. In the light-emitting module with different pitches, a staggered structure will be formed, that is, for any of the middle of the light-emitting modules, the arrangement pitch of the light-emitting diodes or the light-emitting diodes of the two adjacent light-emitting modules are simultaneously The arrangement pitch of the polar bodies is large, or at the same time, the arrangement pitch of the light-emitting diodes in the two adjacent light-emitting modules is smaller. This arrangement of the light-emitting diode unit also makes the light intensity distribution uniform and improves the heat dissipation effect. [0021] The elongated substrate of the light-emitting diode strip can be split into a plurality of substrate units as needed. As shown in FIG. 6 , the LED light bar 500 of the fourth embodiment of the present invention includes a substrate 510 having a long shape, a first light emitting module 520 and a second light emitting module 5 3 disposed on the substrate 510 . 0. The first lighting module 52 0 is disposed at a central region of the light bar, and the second lighting module 530 is disposed at both ends of the light bar. The pitch of the light-emitting diode units 521 adjacent to each other in the first light-emitting module 520 is greater than the distance between the light-emitting diode units 521 of the second light-emitting module 530. The substrate 510 of the present embodiment is divided into a plurality of substrate units 511, a substrate unit 512, and a substrate unit 513, which are different from the first embodiment. The first light emitting module 520 is disposed on the surface of the first substrate unit 511, and the two second light emitting modules 530 at the two ends of the light bar are respectively disposed on the surface of the substrate unit 512 and the substrate unit 513. By dividing the substrate 510 into a plurality of substrate units 511, 512, and 513, when a certain portion of the light bar is damaged and needs to be replaced, only one of the substrate units can be replaced, thereby saving cost. [0022] In summary, the present invention has indeed met the requirements of the new patent, and has filed a patent application according to law. However, the above is only a preferred embodiment of the present invention, and it is not possible to limit the scope of the patent application in this case.
