Stage chasing light is the lighting used in the performance stage. Its main function is to produce a bright light spot, which in stage terms is "a hard and real aperture" that moves as the actor moves within the performance area, hence the name Follow Spot Light. Commonly used chasing light due to the different light sources are divided into halogen lamp chasing lights, metal halide chasing lights and xenon lamp chasing lights three:

Halogen tungsten light chasing light is characterized by simple structure, do not need ballast, easy to use, the power that is bright, dimmable, brightness from 0? 100 infinitely adjustable, cheaper grid, the disadvantage is the lower brightness. 2KW tungsten halogen spotlight can only be used within a distance of 25 meters.

Xenon lamp chasing light is a very sophisticated optical device, light bulb center (cathode spot) must be located in the focus of the mirror, and with the optical lens remain on the same axis, a slight deviation, the brightness uniformity of the projected spot will be Greatly affected. Mirror surface coated with high temperature, infrared, visible light reflection of the film, the surface should not have scratches, dust, oil, or will make visible light reflectance and infrared transmittance greatly affected. Because more than 85% of the infrared light through the mirror, so the back of the mirror equipped with cooling fans, fans, such as failure can cause damage to multiple parts lamps, use must pay attention.

The use of spotlight is particularly important:

1, "chasing light" is a professional stage lighting, the recent years before being used at the wedding scene. Follow light design structure than the average light complex so use

Personnel must be pre-job training. In order to avoid accidents, affecting the wedding scene.

2, now wedding company commonly used chasing light is 1200W, light source is dysprosium lamp, starting power is higher than the normal working power. Therefore, the power to be used alone more than 2.5 square feet of cable to find the electrician directly from the electric outlet. To prevent the power overload trip, even more serious wire debt caused a fire.

3, follow-up light before the official use must start a test machine, because now commonly used built-in transformer spotlight, voltage will result in a long time since the spotlight self-test and can not afford to car. To avoid surprise.

4, the scene after all, how to use a spotlight? There are many friends asking me this. Personally think that more than two or more as well. Because, follow spot light is cold light, light beam is not scattered. Followed by light on the object, the light and backlight contrast is very large, light wedding candlelight little way there is no way to fill light, so a follow spotlight on the face of the couple will result in yin and yang, The general time is the backlight, the stage after the ceremony are all sidelights, a very influential new image. If there are two or more follow-up lighting at the same time lighting, there will be no supplementary light source as the consequences of the appeal.

5, candlelight wedding photographers should pay attention to what? Because wedding companies commonly used domestic spotlight, design, most of the time there is no adjustable brightness of the SCR button, so no matter how far from the spotlight lamp brightness is the same, so it becomes a photographer as adjusted far Department of white balance, and other new come near, if not changed to manual zoom, the camera burst on. Candlelight wedding scene less light, light is not filling, the best choice of models 3CCD and above models, such as SONY190P, SONY digital HD, BETCOMA machine models to ensure clear results. Site selection of two or more with the same level of video equipment, to ensure a comprehensive and complete picture. See the details of the specific shooting points - the wedding photography photography essentials.

6, follow spotlight placement and height requirements. If two lights, a stage newcomer in the stage admission. Another stand in front of stage newcomer fill light and ceremony use. If there is a third follow-up light should be placed in parallel with the second follow-up light away from the corner of the scene, no light before the building is appropriate. Lamp height 2.5 meters above, the lamp does not direct human eyes. Field operation bracket on the table is appropriate. But we must ensure stability, follow spotlight rotation without scratching touch.

7, Follow spotlight equipment use and maintenance precautions. Follow spotlights at the wedding scene are high-end equipment, equipment, high cost, large size, heavy weight, complex operation, so be sure to have a special caretakers. Transport which should be taken lightly, chasing lights have a special turnover box. Stent must be firm and steady, with the two lights to be completed. After power on, open the switch to wait for the machine itself about 5-8 seconds after the indicator light before operating. Methods see the instructions. But we must note that the last shutdown to start the next stop to be stopped more than 10 minutes, do not frequent switching, easy to burn out the light bulb.

Follow spotlights in the performance of the occasions, such as an important role

In some entertaining occasions, chasing lights are an essential equipment, which also appears particularly important in the performance. Today's editor just talked about some of the smaller occasions, follow the attention of light, such as the wedding.

Wedding is a small venue, but a large number of places, in such small and medium-sized venue which, the first spotlight to choose a suitable location, the choice of this location is stress, not random. In general, chasing light is placed on both sides of the stage, is opposite the stage position, under normal circumstances, the chase light will be set up among the audience, because of the angle of the problem, chasing light rotation, must be able to reach the stage In every corner, this is the guideline.

Follow the light to pay attention to safety issues, because the follow-up light are generally used to support the light frame, and the shelves are generally tripods, that is to say, three legs support the ground, and only one steel support from chasing light , In the erection of the time, the general is to use a screw to fix it in the light beam rack, so easy to rotate, but it is easy to fall off, and there are spectators in the vicinity of chasing lights, so the installation Time, we must carefully look at the light recovery frame is intact, while rotating operation, but also pay attention to follow-up lights must not fall off, one side hurt others.

Second, it is necessary to pay attention to the safety of electricity, to know the chasing lights are generally high-power electrical appliances, the lines used are also professional three-phase current, so in advance to check the circuit for aging and other hidden dangers, whether There are bare thread first class.

In the process of using them, white light is generally used to supplement the lack of surface light, but also in the performance, it can also enhance the lively atmosphere of the scene, but also play a prominent focus effect.
