Studio LED Lightings application Notes
1. The color temperature standard makes the picture color more beautiful, and at the same time, the camera whitening is more convenient.
2, LED spotlight light quality soft and hard, very delicate, as a backlight, in the clear outline of the character, the details of the characters are more perfect.
3, LED spotlights are full of light, as a face light to achieve the main and auxiliary surface light application, can maintain or enhance the three-dimensional sense of the human face.
User experience
The host and the recording staff reflected a good feeling from different angles.
The ambient temperature of the studio using LED lamps is reduced and the personnel feel comfortable. The unique cold light characteristics of LED luminaires make the host completely devoid of baking. The overall temperature in the studio is similar to the office environment temperature without turning on the air conditioner.
After more than three years of use, the color temperature of the LED lamps is very constant. Unlike the incandescent spotlights, the color temperature of the light source is continuously attenuated as the usage time is longer. The LED spotlights do not need to be corrected by the calibration in the application.
The failure rate of the lamps is relatively low. The application of dozens of lamps in three years has only been repaired once this year, and only three lamps have circuit failures, and they can work normally after simple repair.
Cloth mode and studio construction
The application of LED lamps provides a richer means and convenient conditions for scene lighting and studio construction.
1. The height of the studio is reduced: the height of the news studio of our new station is 9 meters, but in the application, the suspension height of the lamps is below 3.2 meters. This shows that the height of the new studio in the future can be 3.4 meters of the standard building height. The widening of the studio's tolerance for building heights allows the office to be converted into a studio, which will also make future studio construction more economical.
2. The layout of the performance area is more flexible and takes up less space. The low heat of the LED luminaire makes the luminaire closer to the host. When the performance is arranged, the distance between the host and the background can be as close as 1.5 meters, which is of great practical value for the occasional space of the performance space. .
3. When using LED lamps with sufficient light efficiency, the side light can be canceled when the studio is lighting. Different from the use of three primary color cold light as the surface light from the forward direction to the person, the main and auxiliary light can be applied to the character from the oblique side, and the side light supplement is no longer needed. This lighting method can greatly reduce the amount of lamps used.
Problems and solutions :
As the first person to eat crabs, we have also gone through some detours in the application. The illumination distance and aperture setting are the two most difficult problems encountered with LED lamps, so take the opportunity to share with you.
In the initial stage, the arrangement of traditional lighting is not good. Through practice, we have summarized the suitable illumination distance and incident angle of the LED luminaire. The layout of the performance has been adjusted accordingly, and the effect has been greatly improved.
We also experienced the groping of the camera aperture setting, summed up the aperture setting method after lifting the facial aperture of the person and then raising the first gear.
In general, the aperture set by our current program is generally suitable for LED lighting scenes in the range of 3.8-5. Through continuous exploration and improvement, three years later, we can think that our bold innovation has finally achieved a perfect success.
