The first choice for stage lighting design is PAR lamp series and PAR lamp power supply.
PAR light, also known as downlight or beam light, is a kind of emissive light fixture. Its structure is to install a mirror light bulb in a cylinder, and it is also useful to install a bromine tungsten light bulb in a reflective bowl. Its light beam has the characteristics of fixed and variable angle width. , the spot size is not adjustable. Some varieties of PAR lamps are provided with a baffle (or aperture) on the front side of the light source to control or clear direct light and enhance the controllability of the projected beam of PAR lamps. The reason why PER lamps can play their role on the stage is because par lamp power supply
The PAR light source itself is a light source type simplified lamp with a trinity of parabolic reflector + illuminator (filament) + special lens, which can project a beam with a certain beam angle. The lamp tube of this novel PAR lamp plays the role of regulating the projected light beam. The longer the lamp tube is, the more restricted the light beam of the PAR lamp is, and the smaller the projected beam angle of the tube light is. Therefore, manufacturers provide users with serialized lamps of different lengths to meet the needs of different lighting occasions, provided that they are used in conjunction with par power supplies.
The PAR lamp is simple and lightweight in structure, flexible and convenient to use. It has good light-gathering ability and can project high-luminosity beams, which can be used to shape light beams, light walls, light curtains and other light and shadow shapes in the stage space. And it's cheap. Because of the good controllability of light, different effects can be done, such as beam effect, fixed point effect, etc. The space for installation and hanging is relatively small, and it can be made into a lamp array, which can be used more than one.
