The development of beam lights in these two years is very fierce. Almost every field has selected beam lights, and the beam lights on the swarm are like the stage effects. Without beam lights, they feel like falling behind. Let's talk about my own views here. .

      First, the beam light is focused on the light column, a bright light beam is the pursuit of beam light; moving head light, in fact, should be said that the discharge lamp light pattern, focusing on the light column is the final result of the light spots and patterns. The purpose of the two lamps is different, so there is a significant change in stage lighting for the application.

      Second, the two light sources are different, and the application is different. The beam lamp is a metal halide lamp and the pattern lamp is a discharge lamp. The metal halide lamp used in the beam lamp has a very small beam angle and a higher utilization of the luminous efficiency, so even if the power is not very high, a very bright beam can be obtained. Take the sharpy Beam200 as an example, at a distance of 20 meters, The luminous flux can reach 59,760 Lux, far higher than the luminous flux of the 1200W moving head light of the discharge bulb at a distance of 10 meters! Since the pattern lamp is conical light, the area of ＆#8203;＆#8203;the light is much larger than that of the beam lamp. Assuming that a pattern lamp can illuminate an adult, then a beam light cannot illuminate a child. Therefore, more occasions for beam lights are used in explosive scenes, such as the close-up of the opening show and the jingle dance, with the strobe, to make a passionate visual impact. The pattern lights are more arts that show softness and sensibility. They enjoy aftertaste in whispering and slow dancing. Through the matching of different colors and patterns, they form a soft and beautiful scene, creating a warm and romantic atmosphere.

      Third, due to the difference in the efficacy of the two kinds of light, the actual distance can also be used very different, beam light recommended use distance to 12 meters away, and the use of patterned light 5 meters on it. The real time feels at the time of the production workshop at the incentive time. When the beam lamp is irradiated at close range, it is easy to feel dizzy. The light is too bright. The pattern lamp of the discharge lamp will not have this feeling. So imagine, if you are in a bar with a height of only three to five meters, the light beam on the top of your head dangles like a searchlight, and the guests who are shining are dizzy. How many people can accept it? The use of patterned lights in such occasions is a wise choice. Lights and patterns can appear, creating a good atmosphere, and unwelcome guests and discomfort. On the other hand, in a very high studio, the wide beam angle of the pattern lamp makes the light beam very dark, and it does not reach the lighting effect. In this case, the beam light should be selected. Therefore, the use of beam light and pattern light should be selected according to the distance and effect actually used. Otherwise, the effect would be counterproductive and the effect would not be good.

      Therefore, it is advisable for the user to carry out a match according to most of the occasions and purposes of use. Do not follow the trend blindly. If you use a lot of money, you will not be able to obtain any effect. Even a counterproductive action will be bad.
