[0004] However, the setting of the diffusion baffle requires additional compensation considerations in the calculation of the optical characteristic parameters, and it is easy to cause the uncertainty of the calculation sampling due to the increase of the variation, and the obtained value is not accurate enough. It also increases the manufacturing cost of the integrating sphere, so there is a need for improvement. [New content] [0005] The main purpose of the present invention is to solve the problem that the conventional integrating sphere is not accurate enough in optical characteristic measurement and the manufacturing cost is high. 1〇12〇245(Ρ编号#〇101第4页/14 pages 1012007557-0 M432031 [0006] To achieve the above object, the present invention provides an integrating sphere comprising a first half and a second half a photodetector and an optical fiber. The first half and the second half are connected to each other to form a diffusing space, and the first half has an optical entrance, a first light receiving port and a non- a direct light wall, the light inlet is configured to receive a light source into the diffusing space, the first light collecting port is in communication with the diffusing space, and the non-directing wall indirectly receives the light source, and the light inlet port and the first light collecting port Separately disposed on the indirect wall, the second half has a second light-receiving port and a continuous wall, the second light-receiving port is in communication with the diffusing space, the direct-emitting wall directly receives the light source, and the second The light-receiving port is opened on the direct-emitting wall, and the optical detector and the optical fiber are respectively disposed on the first light-receiving port and the second light-receiving port. [0007] In order to achieve the above object, the present invention further provides a The integrating sphere includes a first half, a second half, a photodetector, and an optical fiber. And the second half is connected to form a diffusing space, the first half has an optical entrance, a first light-receiving port, a second light-receiving port and a non-direct wall a light source is incident on the diffusing space, the first light collecting port and the second light collecting port are respectively connected to the diffusing space, and the non-directing wall indirectly receives the light source, and the light entering port and the first light receiving port The port and the second light-receiving port are respectively opened on the non-direct wall, the second half has a constant wall, the direct wall directly receives the light source, and the photodetector and the optical fiber are respectively disposed at the first The light-receiving port and the second light-receiving port are provided. [0008] The first light-receiving opening provided with the photodetector is opened in the non-direct wall of the first half, because the non-direct wall is not It will be directly exposed to the light source, but will receive the diffused light diffused through the direct wall, so there is no need to add a diffusion baffle. Thus, the photodetector obtains 10120245 (P No. A〇101, page 5) / Total 14 pages 1012007557-0 M432031 When the light is to be measured, it is not necessary to consider the diffusion The influence of the factors can improve the accuracy of the sampling of the optical characteristic parameters and the accuracy of the measurement, and save the cost of setting the diffusion baffle. [Embodiment] [0009] The detailed description and technical content of the present invention are now The schematic diagram is as follows: Please refer to FIG. 1 , which is a schematic structural view of an embodiment of the present invention, including a first half 10 , a second half 20 , a photodetector 30 , and an optical fiber 40 . The first half 1〇 and the second half 2 are each half-spherical and connected to form a diffusing space 50. The first half 1〇 has a light inlet 12 and a first light collection. The port 13 and a non-direct wall 11 are formed on the indirect wall 11 for a light source 6 to be incident into the diffusing space 50'. The light source 60 is from a light-emitting diode die 7〇. The first light-receiving port 13 includes an opening 131 and a channel 13 2 , and the opening and opening 31 extends through the indirect wall 11 , and the channel 132 extends from the opening 131 toward the diffusing space 50 . a hollow tubular shape for fixing the photodetector 3, the indirect wall 11 receiving the indirect Source 60. In the embodiment, the first half 10 further includes a first diffusing coating m attached to the indirect wall 11 , thereby conforming to the integrating sphere requirement of the diffused reflection of the light source 60 in the diffusing space 50. . The second half 20 has a second light-receiving port 22 and a permanent wall 21 . The second light-receiving port 22 communicates with the diffusing space 50 and is formed on the direct-emitting wall 21 . The second light-receiving port 22 is In order to accommodate the optical fiber 40, the direct-emitting wall 21 is connected to the non-direct wall 11 and includes a first circular arc surface 212 and a second circular arc surface 112, respectively, and the first light-receiving portion The port 13 is spaced apart from the light entrance port 12 - the first arc length a, and the second light receiving port 22 is spaced from the light entrance port 10120245 (^^^^ A0101 page 6 / total 14 pages 1012007557-0 M432031 12 - second The arc length b, the second arc length b is greater than the first arc length a. In addition, the second half 20 of the embodiment further includes a second diffusing coating 211 attached to the direct wall 21. In order to meet the integration spheroidal requirements of the diffuse reflection of the light source 60 in the diffusion space 50. In this embodiment, the light-emitting diode die 70 is measured as an example. First, the light-emitting diode is provided by a probe 80. A test voltage required for the polar body die 70 causes the light emitting diode die 70 to emit the light source 60, and the light source 60 is incident on the diffusing space 50 by the light entrance port 12, and The second diffusing coating 211 is irradiated onto the direct wall 21, and the second diffusing coating 211 diffuses the φ light source 60 to generate a first diffused light 611 having a traveling direction different from the light source 60. The first diffused light 611 will encounter the second diffusing coating 211 or the first diffusing coating 111 irradiated to the indirect wall 11 during traveling to form a second diffused light 612. Similarly, The second diffused light 612 will encounter the first diffusing coating 111 or the second diffusing coating 211 again during the running to form a third diffused light (not shown). After the reflection, the light source 60 is in the diffusion space 50, and the first diffused light 611, the second diffused light 612, the third diffused light, and the like are formed into uniform diffused light 61, and are disposed in the first The light detector 30 of the light collection port 13 receives the diffused light 61 for illumination measurement, and the optical fiber 40 disposed at the second light collection port 22 receives the diffused light 61 for sampling and transmission. In an example, the indirect wall 11 is defined as a wall surface of the light source 60 that cannot directly receive the light emitting diode die 70; the direct 21 is defined as directly receiving the wall surface of the light source 60 from the light emitting diode die 70. In other words, the light source 60 emitted by the light emitting diode die 70 can directly illuminate the direct wall through the diffusing space 50. 21, and is irradiated to the indirect wall 11 by the diffusion of the direct wall 21. In addition, the present embodiment 10120245 (P No. A0101, page 7 / page 14 1012007557-0 M432031 is according to the diameter of the light inlet port 12 The first half 1 〇 and the second half 20 are designed to be symmetrical with each other, so that the non-direct wall and the direct wall 21 are also opposite to each other. However, the present invention is not limited thereto, and The area of the indirect wall 11 and the direct wall 21 is changed according to the size of the light inlet port 12, that is, when the aperture of the light inlet port 12 is increased, the light emitting diode die 70 emits the light source. The angle of 60 is wider, so that the longitudinal direction of the indirect wall 1} is reduced by 13⁄4 degrees; when the aperture of the light-injecting port 12 is reduced, the light-emitting diode die 70 emits a narrow angle of the light source 60, which allows the indirect direct The longitudinal height of the wall 11 is increased 'however, usually in design, the The area of the optical port 12 has a maximum tolerance of the area of the integrating sphere. The maximum tolerance is generally that the area of the light inlet 12 is less than 5% of the area of the integrating sphere, so the optical inlet can be additionally adjusted. The distance between the 丨2 and the illuminating diode die 70 controls the angle at which the light source 6 〇 enters the light entrance 12 to match the design of the indirect wall 11 and the direct wall 21. It should be noted that since the first light-receiving port 13 is opened on the indirect wall 11, the photodetector 30 only receives the diffused light 61 and cannot receive the light-emitting diode die. The light source 60 is directly directed at 70, so that the characteristics of the light source 60 can be accurately measured without providing a diffusion barrier. Referring to FIG. 2, a schematic structural view of another embodiment of the present invention is compared with the above embodiment. In this embodiment, the second light-receiving port 22a is opened on the non-direct wall 11. The optical fiber 40 disposed at the second light-receiving port 22a is also received to uniformly receive the diffused light 61 to prevent the optical fiber 40 from being directly exposed by the light source 60. In summary, the first light-receiving port provided with the photodetector is disposed on the non-direct wall of the first half, since the non-direct wall does not have a total of 8 pages/14 pages.
