Description of the Invention (I) ~ Field of Invention: The present invention relates to a device for the distribution of brightness of a kind of lamp, especially a kind of device used for testing sweep lamps. The role of brightness distribution. Background of the invention: The Scanner is a common computer peripheral injury. The basin is mainly illuminated by a lamp, and then the internal charge is thinned. The element captures the image reflected by the text, and takes _ After the image conversion button § hole number, it is sent to the computer for image processing of the document. With the rapid development of the industry, 'the sweeper must also develop in the direction of higher-order resolution'. The 1T industry uses dpi (dot per inch) as the evaluation standard for the high and low resolution of the sweeper. The dpi refers to It is the pixels captured by the scanner within a British pair. The finer the pixels, the more pixels the cat scanner contains within a British pair, so the resolution is higher. For the current development of For high-end scanners, the captured pixels are about 5 // for 5 // the size of the block. However, in the process of the first-order scanner, the main factor that has the greatest impact on the resolution of the scanner and is the most difficult to overcome is the quality of the lamp. Please refer to Figures 1A and 1B. In fact, the lamp tube can be regarded as a combination of countless point light sources. Under normal circumstances, the brightness distribution generated by each point light source should be uniform and the intensity should be sufficient. Please refer to Figure 2A and 2B. But in fact, the paper tube is manufactured in 2 paper sizes in accordance with the Chinese National Standard (CNS) A4 (210 X 297 public love) (please read the precautions on the back before filling this page).

Invention Description (Work) Often because the fluorescent powder on the surface is not uniformly coated and the current is unstable Or manufacturing defects, and some point light sources produce uneven brightness distribution or insufficient intensity. In the past, because the low-level eye-scanning seedlings manipulated relatively small pixels, problems such as uneven brightness distribution or inadequate inspection of some dots were often ignored and the results of concealment were also because of the low resolution. It can be accepted, but for high-level obscure scanners, such defects are unacceptable and are the focus of eager improvement. In the past, the red light tube was mainly distinguished by using a luminance meter. The luminance meter has a camera-like observation window, which can distinguish the lamp tube under test into a plurality of point light sources, and then place the lamp tube in front of the luminance meter. , And observe the brightness and intensity of the first point light source of the lamp tube with the naked eye, and then move the lamp tube until all the point light sources on the lamp tube have been detected. Please refer to Figure 3, but the area that can be detected by the luminance meter used in the conventional technology can only reach the circle size range of the diameter [2], which is the same as that obtained by the high-level scanner. The 5 pixels of the pixel is very different compared to the area, so the area detected by each luminance meter can actually be said to be composed of a plurality of pixels. It can be seen from the figure that even if the result of the luminance meter proves that the point light source The intensity and brightness are normal, but it cannot be used to prove that each pixel in the interior is normal, because for a lamp to be applied to a high-end scanning device, it must be ensured and captured. The intensity and brightness of a point light source reduced by pixels are normal, ^ ---.---! ------------- ^ --------- (please first (Read the notes on the back and fill out this page) 3 A7

Na Cheng = Niu 12 This signal is displayed on the computer 142 screen for warfare Q 'and the rod m is rotated to drive the electric hybrid element 12 words screw 111. Because the lamp can be used as a wire, it is resistant to the surface, and He Yuan only once It can receive the intensity and degree of light emitted by the point light source directly above it. However, for the lamps used in high-end sweeping seedlings, it is not required that the point light sources above it are flawless. Instead, they require The point light source at the pixel position captured by the scanning guard is flawless. Therefore, when the driving device drives the tuner-turning stone element from the front end to the rear end of the screw, as long as the The charge = combination element can take the brightness and intensity emitted by the point light source at the above position, and then perform the test and interpretation to determine whether the lamp is good, and the lamp test function can be achieved. In May, I read the figure 5, which is the flow chart of the method for the test device of the present invention to enter the lamp tube __________ 8 countries — five, the description of the invention (ί), the steps include: first mosquito charge surface compound 2 = Position, final position, and distance of each movement ⑽; then remove the test data stored in the original ^, and at the same time remove the electric device = starting position ㈤; _ charge to the component at the final position ⑽ 'if at the end Position the stop test ⑽, otherwise move forward an appropriate distance (34); capture the brightness and intensity of the point light source above the lamp with the electric hearing element (35); use the electric point light source M to be good and light the light source , And the value of the intensity is recorded, and the process is repeated until the charge port element reaches the final position to complete the test of the lamp (⑹. Among them, the initial position of the light charge element in step (30), the final position The positions are respectively the two ends of the screw, and the distance moved by each time is the distance between the pixels captured by the scanner. Since the present invention is to test the lamp tube 2 with the electric residual element 12, and the charge transfer The pixel area captured by the composite element 12 is Sweeping Miao Crying Sweeping Miao Miao relies on the same area of pixels, and the charge is engaged with the element 12 ^ The motor 112 is used to control the weaving movement, so it can accurately and accurately move the element 12 Position, so that the brightness distribution and intensity of each-point light source on the test tube 2 can be fully described. 'Furthermore, the tube 2 is a good match for Takasaki degrees. Please see Figure 6_, Qian The second embodiment of the lamp luminance distribution test device of the present invention is the same as the first embodiment. The biggest difference between this embodiment and the first embodiment is that this is a known example. The charge-coupled element 12 is fixed on the support frame 15. This paper is suitable for China. National Standard (CNS) A4 specification (210 X 297 mm) 480877 KI Β7 V. Description of the invention (/) It is a fixed element and uses a driving device to drive the lamp tube 2. The lamp tube 2 is slidable Contained in the chute 132_. The driving device includes-a screw 111a and a motor 112a, the lamp 2 is combined with-a screw hole seat 121a ', and the screw hole system of the screw hole seat 121a is matched with a screw. And the screw 112 is driven by the motor 112a to rotate the lamp tube 2 Relative movement with the charge light closing element 12 (that is, the tube 2 slides linearly in the chute 132), and then the test of the tube 2 is completed. Since the remaining components are the same as the first embodiment, they will not be described again. In addition, the test method for the lamp officer 2 in this embodiment is also the same as the first embodiment.
