[Prior Art] A φ Light Emitting Diode (LED) is a light-emitting element made of a semiconductor material. Due to advances in the process, the use of light-emitting diodes has become increasingly widespread, and large-scale billboards, ranging from small flashlights to large outdoor ones, have even replaced the next generation of lighting systems. The quality of the light produced by the light-emitting diodes directly affects the quality of the product, which makes it possible to see the importance of the light-emitting diode. Therefore, the light measurement technique of the light-emitting diode is an important part in the process of manufacturing the light-emitting diode. Usually, the LED products are tested for their electrical properties and their optical properties after fabrication. The part of the electrical detection usually needs to couple the electrode to the electrical end of the light-emitting diode to test its energization state; and the detection of the optical characteristic includes the Luminous Intensity (Iv). , peak wavelength (peakLengttap) distribution, color temperature (Color Temperature) distribution and other detection. After the detection is completed, the light-emitting diodes are classified. Please refer to FIG. 1 , which is a schematic diagram of the mass-produced light-emitting diode testing device disclosed in the Republic of China Patent No. 1258590. The device comprises a control module 10, at least one integrating sphere test module u, at least one test 201126151 t, and a motor unit 13 of the control module Η). The ball test module 11 is turned over 1 () = 13 ° The product test module U has an electrical wheeling 14, a light-integrating ball-integrating ball port 16; the m-test 12 corresponds to the integrating sphere and the light input, and a test board 12 is provided with a plurality of light-emitting lights thereon. Two 7 sets, and = cloth) a plurality of points corresponding to the light emitting diode; J (not shown) ' Μ supply the light emitting diode output and input; wherein, the integrating sphere test group η The light is provided with a predetermined area that can cover a predetermined number at a time; the light-emitting diode 40 is below the mouth, and the predetermined number of the light-emitting diodes can be achieved without moving the product. The optical test of the 17th, and the test, the _ ball test module 11 includes a plurality of probes (not shown) corresponding to the predetermined number of photodiodes 17, and can simultaneously detect the predetermined number by _. The electrical characteristics of the light-emitting diode 17, such as: Forward Bias Voltage (VF), reverse collapse voltage (νζ), ,,, direction Reverse Current (IR), D t Forward Voltage (DVF) before and after heating, Transient Peak (VFD) of VF, etc. Tracing can shorten the electrical characteristics of each LED 26 one by one. Required:: between. Although the technique of Fig. 1 can detect the electrical properties of the light-emitting diode, it still has some problems to be overcome. The first question = Fig. - Known technology in the light-emitting diode of the light-emitting diode = 2 〇, however, the light-emitting diode is not accommodated in the integrating sphere * stone is called the light produced by the light-emitting diode and there is no way The complete calibration is: 2 = hair section 'and is sensed by the integrating sphere. Especially for large viewing angles, light-polar bodies, the optical characteristics detected by the technique can not be accurately determined. The true optical characteristics of the 201128151 polar makeup are therefore inefficient. The second problem is that in the technique of the figure, since the light-emitting portion faces up 1: there is a problem that the detection is difficult. This is because the light-emitting diode is turned upwards and the electrical contact of the light-emitting diode is on the other side of the light-emitting portion: on the bottom surface of the light-emitting diode. Therefore, in order to detect the electricity of the light-emitting diode: it is necessary to use a special electrical connection to detect, increasing the difficulty of construction and detection. In combination with the above-mentioned method, the detection method of the light-emitting diodes is used to solve the problems caused by the conventional technology. 〃系[Inventive content] Gong Tuben "Moon Lift (G-light diode detection method and system, which makes the body of the body of the body of the body of the body, so that the problem of the light-emitting diode is completely The detection of the object, without the problem of material leakage, must be subject to the interference of the light field generated by the external environment = check the results. Therefore, the method and line of the present invention can improve the first pole The detection efficiency of the body light characteristic is provided. The invention provides a method and a system for detecting a light-emitting diode, which is to make the light-emitting part of the 221-pole body be placed in the detection body, and the light-emitting diode is turned on. The upper part makes the electrical detecting component easy:: the electrical connection of the electrical terminal on the surface can be electrically connected, and the electrical property of the second pole can be checked. The method of the invention provides a light-emitting diode detection method. The method includes the following steps: providing a detecting body having a detecting 201126151 measuring space, having an opening on one side of the detecting body connected to the detecting space, and picking up a light emitting diode by a picking mechanism, The light-emitting diode is placed against the opening The light emitting portion of the light emitting diode is housed in the detecting space; the light emitting diode generates a light field in the detecting space; and the light field is detected by the detecting body. In another example, the present invention Provided is a light-emitting diode detecting system comprising: a detecting body having a detecting space therein; wherein the detecting body has an opening connected to the detecting space; and a picking mechanism On one side of the detecting body, the pick-up mechanism picks up a light-emitting diode and places the light-emitting diode on the opening. In another yoke example, the opening is formed on the top of the detecting body, :: When the LED light-emitting diode is placed on the opening, the light-emitting diode is placed in the detection space under the f5 month, and the bottom surface of the light-emitting diode is made to be electrically-powered. The electrical connection of the light-emitting diode on the bottom surface of the light-emitting diode is further detected, and the electrical properties of the light-emitting diode are detected. [Embodiment] In order to enable the review, the features, objects and functions of the present invention are known. It is understood that the following relates to the device of the present invention and The concept of the meter is explained in order to make the reviewer understand the characteristics of the present invention, and the detailed description is as follows: As shown in Fig. 2, the figure is the light-emitting diode inspection/notification of the present invention. The detection method 2 firstly Step 2 Q provides a detection ^ = there is a detection space, and there is an opening on the side of the detector - the opening is connected to the w. The inspection dragon, in this embodiment, is a 201126151 - integral sphere The integrating sphere collects the light projected into the integrating sphere and forms a diffusion effect inside the integrating sphere shell to achieve a uniform light effect. The photodetector on the integrating sphere shell is then used to detect the characteristics of the light. The feature of the integrating sphere is a conventional technique and will not be described here. Subsequently, in step 21, a light-emitting diode is picked up by a pick-up mechanism, and the light-emitting diode is placed on the opening to make the light-emitting diode The light emitting portion of the body is accommodated in the detection space. The light emitting diode system may be a light emitting diode (light emitting diode) of an organic light emitting diode (Φ 〇led) formed by an organic light emitting material or a general semiconductor. LED). The pick-up mechanism can insert the light-emitting portion of the light-emitting diode into the opening by linear displacement motion and rotational motion, so that the light-emitting portion of the light-emitting diode can be completely accommodated in the detection of the detector Within the space. After step 21, step 22 is followed to cause the light-emitting diode to generate a light field in the detection space. In this step, the light-emitting diode is energized, so that the light-emitting diode generates a light field. Finally, step 23 is performed to detect the light field with the detector. Since the light emitting portion of the light emitting diode is completely accommodated in the detecting space, the light field generated by the light emitting diode can be completely diffused in the detecting body, so that the detecting body can sense the light field 100%, and thus The characteristics of the light field are completely analyzed. The detected light-emitting diodes are further removed by the pick-up mechanism in step 24, and the light-emitting diodes are placed in the collection area corresponding to the detection results according to the results. According to the foregoing flow, since the light-emitting portion of the light-emitting diode is completely housed in the detecting body, there is no problem of light leakage. Further, since the light-emitting diode is placed on the opening, the sample is not disturbed by the light field generated by the external environment of 201126151. Combining the above two characteristics, the detecting body can completely detect the light field generated by the light-emitting diode, thereby accurately obtaining the optical characteristics of the light-emitting diode, and classifying according to the detection result.
