Today, when resources are enriched, a good camera can help us capture many wonderful moments, and in a good memory we will not let go of a shining star or a beautiful fireworks. At night, the energy flashlights play a very important role, and many dark and obscure images are quickly restored to life and photo images become clearer. But what are you gonna do when the flashlight breaks down when you take your picture with joy? He's teaching you how to fix the energy flash。
Canon is an old japanese camera manufacturer and at the beginning of the twentieth century the japanese camera industry was very backward, when most people used foreign goods. For this reason, several young japanese people are making national production. Of course, the camera, which was produced by japan itself, began to imitate a high-quality german camera and, in 1934, succeeded in imitating a german card camera in a small factory in tokyo, as well as in developing the first japanese 35 mm focal-level camera, kwanon (in japanese, "the roman word" ), with the early signature of a `megaphone" image, meaning the production of the best camera in the world and making it possible for the user to have a `mixer'-like, variable use camera. It was not until 1935 that kwanon was replaced by canon, which took the meaning of standards and guidelines in english; with the change of name, the sign was changed three times, until 1955, when the sign of the canon, which we saw today, was shaped
Flash light, english. Flashlights are also one way of increasing exposure, especially in the dark, where flashlights help to make the scenes more visible. The use of flashlights can also cause disadvantages, for example, when people are shot, the light of the flashlight may be left behind in the pupils' eyes, and thus in the case of the "red-eye" so that many camera dealers add the "red-eye" feature to the design, before the flashlights turn on, so that the pupils can adapt, and then the real flash can take place. Medium- and low-end digital cameras generally have three types of flashlights, namely, automatic flashing, red eye elimination and turn off. More advanced products also provide “compulsory flashing”, even “low-speed flashing”。
Maintenance of camera flashes:
1. If the flashlight fails, if the flash switch is able to continue, it is recommended that the battery be removed and flashed. It can also be discharged with a 1k/2w barrier at both ends of the energy storage capacitor c2. Because of the direct flow pressure between 100 and 300 volts at both ends of the capacitor after the flash, it is recommended that electrical discharge be carried out with two sharp-mouth pliers. In addition, when flashlights are charged, the current begins to be larger, around 3a, then gradually drops to about 100ma as the recharge time increases. So, at the time of testing, the current meter should have a range greater than three ambers, or it would have been damaged。
2. In the event of a malfunction in the use of the flashlight, the first check is whether the battery voltage is powered, whether the spring of the battery seat is broken or not there is poor contact with the tentacle. If no current output is found in the power segment, the power can be disconnected, and the flashlight will be checked for goodness at the rx1 stage to trigger the k2 contact with the switch, whether the line has been dropped or welded. If an output current of less than 100 ma is detected in the test, the high frequency squeals can be heard and the direct flow converter should be checked for normality. Because of normal working currents when flashlights were charged, due to the gradual reduction of the 3a current and the high frequency squealing, bg concussion tubes were working normally. If the current at work is a fixed value, no drop, touch bg feels hot, it should disconnect the power, check if there's a short circuit in the circuit, whether c2 has a severe leak, whether the polarity is reverse, whether the transformer has a partial penetration. If the zd is not bright, it is usually the r2 short road, zd welding or damage. If it's always bright, it's usually the energy storage capacity c2 is broken or welded. If the fast door is pressed, the flashes of the flashlight cannot be restored, they are the result of spring fatigue. The blisters are glowing, pressing flash-tip switch k2, the flash light is not flashing sd, and k2 should be checked for good contact. If there are no questions about the presence of welds in r3 and c3, then the surface voltage of c3 should be measured by a table, which should normally be around 120 to 180 volts. It is worth mentioning that the failure of the pulsed high pressure to break the lead line due to the flex welding of the flash tube is not uncommon and it is recommended that it be carefully checked。

That's the maintenance of the canyon flashlights and the full range of related knowledge. Are you going to learn more about the maintenance problems associated with the camera flashlights? The presence of flashlights allows the camera to present us at night with the clearest picture of the high quality. However, the editor also wishes to remind you that professionals must be trained in the maintenance of flashlights when they encounter problems they do not understand. If it is too reluctant, it will only make the results worse. Maintenance is the process of developing hands-on skills, and it is also the process of acquiring knowledge from others, hopefully you will learn at an early stage。
