In all kinds of professional stage performances and lighting and audio rental activities, led par light are the most commonly used lamps. According to the different colors of lamp beads, the efficacy of par light is determined.
Red, green, blue that three primary colors are mainly used for randering effect and setting off the effect for the stage atmosphere.
Its warm white color temperature of 3200K, which is used for the stage surface light. It is required to have a high color rendering index cri90 + or more, and to present the true colors of the people in the stage background.
Since the beginning of 2019, according to the market demand, dual color temperature surface lights have been added, in one hand, to supplement the brightness of the stage, and on the other hand, dual color temperature adjustment has achieved a simple CTO simulation effect.
When there is a need for stage brightness, it can be lit immediately. The following will explain in detail the differences in use between the cob light and the LED washing light.
As a warm light source, the surface light requires a color temperature of 3200K, but some customers choose 2800k according to the scene. (in recent years, some people have also chosen dual color temperature white light, adding 5600k color temperature lamp beads).
Generally, the whole stage area is illuminated from the top or both sides to provide basic lighting and front lighting for the stage. The surface light needs to cover the whole stage evenly, and its light is soft. It mainly plays the role of lighting and provides good shooting effect for photography.
Professional surface lamps usually have very high requirements for color rendering index. The general requirements for photography studios are cri95 and stage cri90. Traditional surface light lamps usually have high power. The surface light lamps used for stage performances and rentals are generally 800w-1000w.
A traditional bulb is used to emit light, and its brightness is adjusted through a thyristor box, which requires high power supply for the venue; Since 2012, with the development of LED chip heat dissipation and packaging technology, LED has gradually replaced the traditional light source, and 150W cob LED can replace 800W traditional light source. At the same time, the disadvantage of higher color rendering index and lower brightness has shown.
Led washing light are mainly used to change colors and render the stage. The main colors are what we often call RGB three primary colors. Through the mixing of these three colors, 16.7 million different colors can be obtained. So how can we distinguish the quality of color beads?
If when three colors interaction, they will mix colors into a new color. and If you can get the right magenta, cyan, yellow and white, the quality of the light source of this light is very excellent.
In short, whether it is a traditional PAR64 downlight or a LED high color rendering index lamp bead, the surface light is mainly used for lighting, while the washing light is used to change the color of the scene, playing the effect of rendering and setting off the environment. These two cannot be mixed, and the ideal stage lighting effect can only be obtained through reasonable combination.
