working principle

■ Beam lamp

Working principle: It is realized by using the light source of the short focal length focusing principle and the lens focusing effect. At present, the Z popular for major performances is mainly suitable for hot singing and dancing, relatively hot occasions, and variety shows to mobilize the atmosphere

■ Swinging head lamp

Working principle: 220V - rectifier - trigger - bulb - temperature controller - zero line

220V power is first supplied to the rectifier and then output to the B end of the trigger through the rectifier. The other two terminals of the trigger are connected to both ends of the bulb, and then output to the zero line through the temperature controller.

The trigger only works when the bulb is lit. It is mainly to give a high voltage to both ends of the bulb to make the gas in the bulb light up due to electrical changes. When the light bulb is on, the trigger will not work inside, but it is equivalent to connecting the rectifier. (The same principle as the old fluorescent lamp). The function of the rectifier is to connect the light bulb in series with the light bulb to play the role of voltage divider after the light bulb is on.

Use occasion

■ The beam lamp is a metal halide lamp, and the pattern lamp is a discharge bulb. The metal halide lamp used in the beam lamp can obtain a very bright light column even if the power is not very high because of its small beam angle and higher light efficiency.

Because the shaking head lamp shines conical light, the light spreading area is much larger than the beam lamp.

Beam lights are used in more occasions for explosive scenes, such as close-ups of opening shows and hot dancing, with stroboscopic, to make passionate visual impact;

Shake the head lamp is more to show the art of tenderness and intellectuality, and enjoy the aftertaste in the slow dance. Through the matching of different colors and patterns, form a beautiful and beautiful scene, and create a warm and romantic atmosphere.

If you are in a bar with a height of only three to five meters, it is a wise choice to choose a shaking head lamp, which can produce beams and patterns and form a good atmosphere, which will not make guests uncomfortable, but also bring them discomfort.

On the contrary, in a very high studio, the wide beam angle of the shaking head lamp will make the light column very dark and cannot achieve the desired lighting effect. Therefore, in this case, the beam lamp should be selected for this occasion, unless there are other special requirements for the lighting effect of the venue.

Therefore, when selecting beam lamp and shaking head lamp, it is necessary to determine the distance used and the desired effect according to the actual site.

Use differences

■ The light of the beam lamp can shoot far and can be used according to the needs of the stage and the program; The shaking head lamp is generally used to render the performance lights in close cooperation with the stage.

Generally, it is better to use the shaking head lamp at a distance of less than 5m. If the distance is too large, it is better to use the beam lamp at a distance of more than 12m.

It can be clearly and truly felt when the effect performance test is conducted in the production workshop. When the beam lamp is illuminated at a close distance, it is easy to form a feeling of dizziness because the light is too bright. The shaking head lamp of the discharge bulb will not have this feeling.

The shaking head lamp can be used within 12 meters, and the beam and pattern can appear, forming a good atmosphere, and will not cause discomfort to the guests. On the contrary, in a very high studio, the wide beam angle of the shaking head lamp makes the light column very dark, and can not achieve the lighting effect. In this case, the beam lamp should be selected. Therefore, the selection of beam lamp and shaking head lamp should also be based on the actual distance and effect.

In terms of market demand, no matter what occasions and scene applications, general consumers will prefer to choose beam lamps. Because the beam lamp actually has the function of shaking head lamp. The beam lamp will have more complete functions and a wider range of use than the head lamp. If it is not for the special needs of the venue, it is generally recommended that you choose to buy beam lamps, unless the venue is too small to meet the conditions for using beam lamps.

Difference between beam lamp and shaking head lamp

■ It is not difficult to understand that the beam lamp is a light that can produce a beam of bright beams. It is a popular stage light shaking beam lamp at present. What he emphasizes is the process of lighting. The light produced at a distance of 100 meters is almost as large as the light produced, and it is almost parallel light, which can produce a similar effect to the laser beam.

■ The shaking head computer lamp is composed of optical, mechanical, electrical and program control systems. The three systems are interconnected and organically combined to meet the needs of light, color, speed, direction, effect, heat dissipation, noise, positioning and other elements.

The important thing of beam lamp Z is the light column, and the bright light column is the pursuit of beam lamp; The shaking head lamp focuses on the result of the beam Z, namely the light spot and pattern. The two lamps have different purposes, so the application occasions have changed significantly.
