[Prior Art] As shown in Fig. 1, the integrating sphere is a hollow spherical cavity, and the inner wall of the spherical cavity is generally a reflective coating. When the integrating sphere is applied in practice, the light-emitting element 7 is emitted. The light beam is injected from the input hole below the integrating sphere, and after being diffused and reflected by the inner wall of the spherical cavity, the light energy absorbed by the cavity wall is determined according to the material of the coating, and the light-emitting elements to be tested are collected and collected in all directions. The emitted light is used by the spectral energy analyzer 14 to sample the optical power, waveform and energy from the output aperture above the integrating sphere 1 to calculate the original incident beam of the light-emitting element 70 to be tested. According to the above measuring structure of the integrating sphere 1, the light source to be tested needs to be placed in the integrating sphere 1, and the measuring light source needs to be taken out from the integrating sphere by the measuring sphere, which will cause the threshold of the measuring speed; in addition, the integrating sphere 1 In addition, it is not only necessary to additionally set the shutter to receive light, so as to prevent the direct beam from directly entering the sensing device; and the aging deterioration degree of the coating material of the inner wall of the ball cavity is interfered with by the spectral energy analyzer 14 to analyze the original incident light parameter. The quasi-breakage; in addition, the portion of the beam reflected from the input hole below the integrating sphere to the light-emitting element 70 is partially reflected back into the integrating sphere, and the surface condition of the light-emitting element is different. The difference, even if only the variation of 1% is assumed, will cause significant difficulties in measurement and subsequent calculation accuracy. Most seriously, once the volume of the light source to be tested is slightly larger, the integrating sphere not only causes an increase in the cost of the installation, but also causes troubles in the installation due to the large volume, forcing the architecture to be measured only in the laboratory. Use, do not deviate from the general production line; 5 201013165 Moreover, the size of the integrating sphere has its limit, when the object to be measured is, for example, a tens of centimeters long and narrow shape light bar, the corresponding integrating sphere diameter needs to reach The high cost, the slowness of the test object entering and exiting, the measurement is not easy to be correct with the above various factors, all of which proves that it is not good for the mass production of the factory. Not to mention the future size of the liquid crystal display. Increase, in line with this trend, the light bar itself is bound to grow gradually, farther than the current score of the integral ball can bear the responsibility. The new patent No. 7 purchased by the applicant in this case is shown in Fig. 2, and discloses a detecting machine from 2' whose sensing device 23 includes at least one solar cell (solar cell Ph〇t〇voltaic), In terms of the simple structure of the solar cell and the reasonable price, the detection machine 2 is cheaper and more competitive in the market; on the other hand, it has the characteristics of low reflection and high absorption, effectively avoiding the error caused by the reflection of human light. 'And increase the amount of hemp sensitivity; due to the good solar cell photo-detection characteristics, there is no need to worry about the change of the reflection coefficient of the test object; moreover, a spectral energy analyzer 24 can be used to obtain the spectral energy distribution of the light-emitting component 7 to be tested, so that The measurement accuracy is improved. In particular, by the combination of W solar energy, the effective range of the measurement range ^ p conforms to the continuous increase of the light source to be tested. However, this prior art only refers to the static sensing after the position of the light source to be measured. The pair of tests is performed. (4) The entire wire to be tested is not detailed. When a plurality of light-emitting elements are present in a group of light sources to be tested. What is wrong with the material of the light-emitting element; that is, if a problem occurs in a certain light-emitting component, it is necessary to further confirm the component of the light-emitting component through a step to further correct the correction. If you change the Lue's correctly, all the light-emitting components of the paid-up grades are all good products that meet the test standards, and quickly confirm the non-good test components, which will speed up the subsequent correction processing speed to improve the yield. In particular, this type of resolution is based on the same automated workflow of 6 201013165, and it is possible to quickly inspect the light-emitting components to be tested* (4) in the detection process, and solve the dilemma of manufacturers of light-emitting components and _light-emitting components. The best solution. SUMMARY OF THE INVENTION An object of the present invention is to provide a light-emitting component detecting machine which can quickly and clearly indicate which of a plurality of light-emitting elements in a light-emitting component is unqualified.

The present invention is also a purpose of providing a method for detecting a hair training component that does not require complicated devices and actions, and can be quickly-refined. The present invention relates to a light-emitting component having a plurality of light-emitting elements, a light-emitting component having a plurality of light-emitting components, and a light-emitting state of each of the light-emitting components, wherein the light-emitting components are arranged along a length direction.

Component φ component illuminating state, wherein the detecting splicing comprises a pedestal, a susceptor disposed on the pedestal for carrying and enabling the illuminating component to emit light, and the accommodating device is disposed on the pedestal a sensing device that emits 70 pieces of light and converts it into a sense signal output; and a set of moving devices that move the load enabling device and the turning device relative to each other in a moving direction The method comprises the steps of: a) arranging the illuminating components in the length direction. And placing the load-carrying device as the light-emitting component to be tested and transmitting the light-emitting components of the light-emitting component by the load-carrying device, b) Transmitting, by the device, the load enabling device and the sensing device in the predetermined moving direction such that the light emitting elements of the light emitting component to be tested sequentially enter and/or leave the range of the sensing device; and e) The job sensing is performed according to the light-emitting elements entering and/or taking off the sensory state, and the scale sensing illuminating amount is changed according to the sensing signal of the illuminating element «and _. According to the above, the present invention proposes a Wei component detecting machine having a plurality of light-emitting elements and a detecting method thereof for making the sensed light-emitting brightness by allowing a plurality of light-emitting elements in the light-emitting component to sequentially enter/detach the sensing range Step by step, simple increment or decrement, 'deny increase and decrease state and pre-deposit symbol', according to the speed of entering / Lin, immediately calculate = the problem of the light-emitting component in the position of the light-emitting component towel; not only with the middle of the person who owns the case Compatible and echo each other, and _step to achieve the 'instantly identify the wrong single-components in the automated inspection operation, accelerate the follow-up process, improve the output rate, especially the length of the light-emitting components to be tested, more suitable demand. 8 201013165 [Embodiment] The technical content, features and effects of the present invention will be clearly described in the following detailed description of the preferred embodiments with reference to the drawings, and for convenience of description, The illuminating component has a plurality of illuminating components arranged along a length direction, and omits a bracket circuit which is necessary for the base of the machine to avoid turbulence of the drawing. As shown in FIG. 3, this is the first embodiment of the present invention. The light-emitting component detecting machine is configured to supply the hair-emitting state of the light-emitting component 7 of the complex light-emitting element 7G, and includes three bases 30 and one. A set of load-carrying devices 3 for carrying and enabling the light-emitting assembly 7 is provided with a set of sensing devices capable of simultaneously sensing the plurality of light-emitting elements 7 and a set of mobile devices 32 for driving the load-carrying device 31. 3 and FIG. 4' 'This is the first embodiment of the present invention and its detection flow' and is taken as an example of a solar cell domain measuring device 33, and a light bar having a plurality of light emitting diodes as a plurality Illustrator of the illuminating unit 7G. When the detecting machine 3 starts to perform the detecting, as in step 61, (4) the illuminating unit 7 to be tested is placed at the load-carrying device 31, so that the illuminating unit 7 of the illuminating unit 7 to be tested faces upwards and is located at Far® _ position 33 Senses _ position G; performance _ 62, the illuminating component 7 is enabled by the load-carrying device 31, so that the plurality of illuminating elements are illuminated at %. It has 60 LED dies and is divided into six groups that are interlaced and interlaced. Light does not limit all LEDs when the day and the grain are all light. You can also talk about, for example, a group of ten crystal grains. The same five are not lit. The other five groups are not lit for the time being. For convenience of explanation, in the definition step 63, the moving device 驱动 drives the direction in which the load-carrying device 31 moves as shown in FIG. $, which is called a predetermined moving direction, and the predetermined shift is 9 201013165. «The length direction of the new member, so that the first of the illuminating member 7 to be tested, the illuminating first framing member % enters the sensing device 33 from the above-mentioned preparatory position, and the illuminated illuminating element The 7Q system is like a strange speed, and the scarf is added in sequence. As shown in Fig. 6, all the light-emitting elements 70 under test completely enter the sensing device 33, and the position is called the full sensing position. Assuming that all of the manufactured illuminating elements have normal brightness and low difference in illuminance between the two, the measured brightness will be as shown in Fig. 9. From the preliminary position 〇, there is no brightness, φ is incremented to the corresponding full sensing position 81. The maximum value. Of course, if you are familiar with the technology It can be easily understood by the domain that the above-mentioned procedure for measuring the incremental illumination can also be reversely operated as a decreasing measurement procedure. For convenience of explanation, the first of the illuminated light-emitting elements shown in FIG. 7 is about to be separated. When the sensing range of the sensing device 33 is measured, it is referred to as the preliminary disengagement position 82; and is gradually measured until the measured light-emitting element 70 reaches the measurement position of the sensing range of the full number of the sensing devices 33 as shown in FIG. 'According to the second half of Fig. 9, the measured brightness is prepared to be off the maximum value of the position 82, and gradually decreases to the original reference brightness corresponding to the measured position E. 〇 As shown in Fig. 8, then follow step 64, Optionally, one of the two metric sensing processes (or both) is processed by the processing device 35 in accordance with the sensing signals and time sequences corresponding to each other. In step 65, the sensing device 33 is estimated by the sensing signal ( The solar cell is associated with a change in the electrical state of the light-emitting state of the test object, and it is detected whether the light-emitting component is a good product. Once any of the illuminating elements 70 have not reached the predetermined standard, as shown in FIG. 1A, the original incremental upward trend (or the decreasing decreasing curve) will produce a non-ideal flex, which can be calculated in chronological order (1). Light-emitting components that do not meet the standard of good quality: Where is the location. Since the length of the light bar is increasing, for example, as shown in FIG. 11 of the second embodiment of the present invention 201013165, when the detecting machine 4 is limited by space, the sensing range of the sensing device 43 cannot cover the light-emitting component 7 at the same time. All the light-emitting elements in the same; the sensing result will be as shown in FIG. 12 or FIG. 13 'still from the above-mentioned preparatory position 0 to the fully-sensing position of the last* entering the sensing position of all the lighted ones. Or the position of the defective light-emitting element is clearly analyzed from the state of the preliminary disengagement position to the completion position E. In particular, since the speed of mechanical movement is much lower than the speed of the electric signal, the light-emitting elements on the left and right sides shown in FIG. 11 belong to different illumination groups, respectively, or the example Φ such as two (or even more) light rods.
