Description of the Invention: [Technical Field] The present invention relates to a light guiding jig, and more particularly to a light guiding jig, a testing machine and a light guiding device for an edge type LED light bar. 5 [Prior Art] Using a white light LED light-bar made up of a plurality of white light-emitting diodes (LEDs) arranged side by side on a flexible printed circuit board as a notebook computer The light source of the display backlight board has replaced the traditional CCFL cold cathode tube light tube, which has been widely recognized by users in the industry. In particular, the white light-emitting LED light bar whose light-emitting direction is parallel to the direction of the circuit board is more suitable for the ultra-thin light guide plate, so that the amount of the edge-emitting LED light bar is increasing. The side-emitting LED (Side-View LED) light bar is a plurality of LEDs 14 as shown in FIG. 15 and arranged side by side with a joint 142 soldered on the soft board 20 as shown in FIG. 2 and the light-emitting surface 144 Exposure to the same side, and a plurality of light bars arranged in parallel with each other as shown in FIG. 3 are formed on the flexible board 20, and a dividing line 22 is formed between the light bars 1 to facilitate the light bar i from the soft board 20 Separated on. 20 Since the width of the circuit board 12 of the mother-edge type LED light bar 1 itself is / several millimeters, the respective light-emitting directions are toward the upper left and/or lower right direction of the drawing. In order to reduce the production cost and increase the yield, only the dividing line 22 spacing is left between the adjacent two light bars. Therefore, if the light bar 1 is not removed from the circuit board first, after the power is turned on, the light-emitting line will directly illuminate the adjacent light bar 1 i at 200933089, and it is very difficult to directly measure the light flux from the side. Each side-emitting LED light bar 1 is detached from the entire flexible board 2, and placed in a test fixture for measurement, which adds a lot of man-hours and slows down the production process without any need to reduce the yield. 5 ❹ 10 15 Ο 20 On the other hand, LED dies are still subject to a number of process factors during the manufacturing process, and the core wavelength, luminescence brightness, etc. are slightly mutated. On the other hand, since the sensitivity of the human eye is quite high, as long as the LEDs used in one LED light bar are different from each other, even if they are still within the allowable range of the product, the user will subjectively determine the LED light. Sticks are inferior products. Therefore, all the dies used in each LED light bar need to be individually tested for color distribution and brightness, and cannot be detected with only the entire light bar. In addition, the general edge-emitting type LED has an illumination angle covering almost the entire 180-degree spatial range. Therefore, when separately measuring the luminous flux of each led die (t〇tal flUX), it is often necessary to use an optical integrating sphere. The LED is condensed at all angles and then measured. Therefore, the measurement speed is very slow. The edge-emitting LED light bar has market demand. When testing, it is necessary to first remove the light bar from the substrate and fix it to the fixture. Also, check each _ die used on it, and use the integrating sphere for inspection. And taking a long time will undoubtedly cause the cost of the manufacturing inspection process to be reduced, the detection rate cannot be improved, and the output efficiency is limited. Therefore, if a kind of convertible beam traveling direction can be provided, the illuminating beam is turned toward the direction of the detecting instrument, so that at least one strip 6 is detected at a time. 200933089 Edge-emitting LED light bar, even without first obtaining a detection result from the circuit board Light scheme. Simultaneously detecting the luminous flux of a plurality of light bars, disassembling the light bars one by one, and quickly and accurately determining the fixture, which should be optimal for solving the above problems 5 [Summary of the Invention]

The above structure is more applicable to an edge-emitting type LED light bar testing machine for testing the light-emitting state of a side-emitting LED light bar having a minimum predetermined interval and a parallel arrangement of the plurality, and the machine comprises: a group of conveying The conveying fixture for waiting for the edge-shooting type LED light bar; a set of control devices; a set of light guiding fixtures comprising: a set of frame trusses; the plurality of respective connected to the frame, respectively corresponding to the side-emitting LED light a light guiding device for the light-emitting position of the bar, the light guiding device respectively comprising a light-emitting surface facing the side-emitting LED light bar, a light-emitting surface facing the light-incident surface, and a light-emitting surface at an angle with the light-incident surface, and a light-emitting surface a transparent light guiding member that reflects the light beams incident on the light incident surface to a reflecting surface of the light emitting surface; the group is driven by the control device to drive the light guiding fixture to move with the waiting for edge detecting type coffee bar a driving device for moving; and a set of 15-light measuring instruments corresponding to the light-emitting surfaces of the light guiding fixture.

Each of the light guiding devices 36 includes a plurality of hexahedral light guiding sheets 5 each having a light incident surface, a light emitting surface, and a reflecting surface (not shown) as transparent light guiding members. The hexahedron light guide 5 is exemplified by a high-transparency plastic material in this example, and the application is as shown in FIG. 5. Each light guide 5 must correspond one-to-one to the edge-emitting LED 14 and The reflecting surface 54 is assembled to the pedestal 32 as a junction=face. Referring to FIG. 6 at the same time, one surface of each light guiding sheet 5 is designed as a completely smooth light-incident surface 5〇, and faces the light-emitting surface 144 of the LED 14 in the light-receiving rod, respectively, and the size of the light-incident surface 50 is smaller than that of the side surface. The light emitting surface 144 of the LED 14 is slightly larger to increase the incident light flux. In this example, the surface 52 which is above the figure and is perpendicular to the light-incident surface 5 is a light-emitting surface, and the other surfaces are removed by the light-receiving sheet 56 or the coating surface. The metal reflective film 58' with excellent reflectance of the cloth makes the light beam entering the light guide sheet 5 unable to escape easily from the other J faces, thereby ensuring that the luminous flux of each of the side-emitting LEDs 14 is only 10 200933089 by its corresponding light guide 5 Output. 5 ❹ 10 15 Ο 20 The light beam of the led die is subjected to total internal reflection in the hexahedral light guide 5, and is reflected not only to the light-emitting surface 52 via the reflective surface 54 opposite to the light-emitting surface 52. The light is emitted directly from the light exit surface 52; and other light is reflected back into the hexahedral light guide sheet 5 via the reflective sheet %, the metal reflective film 58, and can still pass through the reflective surface 54 and other sides. Reflecting, most of the light will be emitted through the light exit surface 52. If the material of the retroreflective sheeting 56, for example, the metal reflective film 58, has a higher reflection efficiency, the greater the ratio of the exiting surface 52, the more accurate the measurement of the luminous flux of the human light; the light entering the light-emitting type LED 14 is placed close to the edge-emitting LED 14 On the face 144, almost all of the light rays emitted by the LED 14 enter the inside of the hexahedral light guide 5. Some of the aforementioned multiple reflected light rays may pass through the light incident surface 5 〇 back to the edge-emitting LED 丨 4, and are absorbed by the LED member to cause loss. In order to reduce the light loss back to the edge-emitting LED 14, the area of the light-emitting surface 52 can be designed to be much larger than the area of the entrance surface 5 ,. In this example, the ratio is designed to be more than five times. Of course, as long as the absorption ratio is fixed, even if the ratio is less than five times, the correct value can still be obtained by adjusting the compensation. In order to obtain a relatively uniform light output, it is easy to determine the range when measuring by using the instrument. On the light-emitting surface 52 side of the hexahedral light guide sheet 5, a set of diffusion devices 60' may be further added to make the light output more uniform; When the optical instrument is measured, the range of the hexahedral light guide 5 is evaluated by the software to add the corresponding luminous flux to obtain the corresponding total luminous flux. 11 200933089 A general two-dimensional luminous flux instrument uses a lens to image, and then uses a two-dimensional CCD image sensor (2D CCD image sens(K) 5 10 15 ❹ 20 to calculate the luminous flux at each point in the two-dimensional range, but The maximum value of the field-of-light field FOV (field 〇f Wew) that can be achieved by the lens is only about 70 to 80°. Therefore, if the luminous flux is to be more accurately measured, the light guiding device of the present invention must have a characteristic. That is, regardless of the angle (typically in the range) of the light emitted by the side (four) LED force, after passing through the light guiding device 36, the angle of the light output from the light emitting surface 52 can be collected within ±40. The two-dimensional luminous flux meter accurately measures the luminous flux of the edge-emitting LED 14 . Therefore, in the present embodiment, directly above the diffusion device 60, the brightness of the mirror is increased as shown in FIG. 7 1562. The direction of the mirror is perpendicular to each other in the X and γ directions, so that the angle of the light can be concentrated within ±0 by the action of the prism in the Z direction. For example, a certain light is emitted by the light exit surface 52 in the direction of the arrow. The angle α is 70°, and the refraction will be generated after passing through the prism 62, and the ray angle 0 can be converted to 30. The light exit angle of the prior art brightness enhancement film can be controlled within ±40 degrees. Fig. 8 is a second embodiment of the present invention. For example, a partially enlarged schematic view of the light guiding member of the light guiding device, the hexahedral light guiding sheet 5, the light emitting surface 52, may be a full smooth surface or as shown in the figure, a microstructure diffusion point 522 is provided, in practical applications, the microstructure The diffusion point 522 can be a pit or a bump; of course, the reflecting surface of the hexahedral light guiding sheet 5' can also adopt the same structure, and the micro-junction 12 200933089 can be used as a diffusion point, and can still be a pit or a bump. Figure 9 is a schematic view of the light guiding fixture of the present invention in combination with a light measuring instrument, as long as the converted luminous flux of the light guiding fixture 3 is proportional to the luminous flux emitted by the soft plate 20 including the edge-emitting Led light bar, Using a light 5 degree spectrometer 8 and its lens 82, such as a two-dimensional luminous flux meter to measure the luminous flux of each edge-emitting LED of all edge-emitting LED light bars in the flexible board 2, for quality inspection. According to the foregoing description, the hexahedral light guide 5 The exit angles are all controlled within the acceptable optical angle of the two-dimensional luminous flux instrument. Therefore, in the two-dimensional CCD image in the two-dimensional luminous flux instrument, it is determined that the light-emitting surface 52 of each hexahedral light guide 5 corresponds to The pixel in the CCD 'calculates the total luminous flux and color coordinates of the corresponding brightness and chromaticity of each pixel according to the CIE, that is, the total luminous flux and chromaticity of the corresponding side-emitting LED can be obtained. According to the above-mentioned light guide jig, it can be applied to the test fixture shown in FIG. 10, and the transport fixture 7 controlled by a group of control devices 9 delivers the fixed side of the side-fired LED light bar to be treated. Measuring position, and driving, by a group of driving devices 4, the light guiding fixture 3 is moved relative to the light bar to be tested (not shown), so that the light guiding device (not shown) 2〇 corresponds to each light bar to be tested, thereby The light beam emitted from the light bar is guided to a light measuring instrument 8 corresponding to the light emitting surface of the light guiding fixture 3 as a two-dimensional luminous flux meter. Of course, as can be easily understood by those skilled in the art, the transparent light guide is not limited to the hexahedron shape and does not limit the plural transparent guide 13 200933089 light member must be coupled to a base frame, as shown in FIG. 11 and 12 is also shown that the plurality of light guide triangles 5" as the light guides" are divided into the light surface 5"" and the light exit surface 52", and the rest are the reflection surfaces 54", and adjacent to the adjacent light guide triangles 5" Between the side reflecting surfaces 54", the adhesive layer 58 is applied as a 5 connecting member, so that the light guiding triangles 5" corresponding to the plurality of LED dies 14 on the same light bar are collectively combined into a long strip light guiding device, For synchronous lifting and moving, and achieving the synchronous conversion of the same row of LED ray illumination © beam traveling direction, for the purpose of obtaining the respective luminous flux without the need to disassemble the light bar to achieve the purpose of detection. From the above description, 'the invention is sufficient
