LED front light development history
the front light is a kind of stage lighting, and the development of stage front light is also developed with the development of stage lighting technology.
In the earliest stage, open-air or semi-open-air performances took daylight as the light source; then the indoor or night performances took bonfires and candles as the light source; at the advent of tungsten bulbs in the early 20th century, which promoted the progress of stage lighting technology.
until the 1960s, the successful development of the LED light source has brought about a major innovation in stage lighting technology (the white light LED for lighting only developed after 2000).
Today, LED stage lighting has become one of the important lighting fixtures for stage lighting.
The difference between moving head LED front light and conventional front light
LED front light has therefore become a topic that everyone is more concerned about. The current LED front lights are mostly used in studios, meeting rooms, multi-function halls, banquet halls indoor and outdoor small occasions.
Like large and medium-sized theaters, auditoriums, studios, stadiums, concerts... you can rarely see LED front lights! This has to talk about the advantages and disadvantages of LED front light.
Energy saving and environmental protection, long life of the light source, soft light, small and light, high cost performance are the advantages of LED front light; the disadvantage is that the light effect is limited!
For example, the common LED stage front light (COB lamp beads, LED chip lamp bead front light), among which the LED panel lamp suitable for meeting room lighting occasions generally has an effective distance of about 6 meters, and it is suitable for COB lighting occasions in banquet halls.
Area lights generally have an effective distance of about 15-25 meters. The LED par lights that are also suitable for multi-function halls and banquet halls have a light efficiency of about 12-20 meters. LED spotlights that are suitable for studios and other occasions generally have an effective distance of about About 15-20 meters, the general light efficiency of LED imaging lights is about 20-30 meters.
Of course, there will be a certain gap in the luminous effect distance of the light source of different power! But it is far from meeting the needs of medium and large-scale performances and activities.
Advantages and disadvantages of moving head LED front light
focusing moving head LED front light, which is more convenient to use and saves manpower, but it still cannot satisfy medium and large luminous effect distances.
The needs of performances and events! As a result, the selection of front light for medium and large-scale performances and events is still based on high-power LED front light, such as 300W focusing LED moving head front light, 400W focusing LED moving head front light, etc.
The biggest advantage of large and medium-sized performances and events is that the long-distance front brightness is sufficient, and it has a focusing function; the director can use the artistic treatment of the lighting engineer to create different shapes according to the stage scene, abandon stray light, and highlight the theme.
To meet the needs of performances and activities. The advantages of the moving head LED front light are self-evident, but the disadvantages are also obvious: the cost of the lamp is high!
Practical application of moving head LED front light
LED front light is obviously superior to LED par light and LED imaging light that cannot be moved.
The LED front light is programmable, and can be programmed to show the effect of the lamp according to the actual use needs; the functions of moving the head, focusing and so on make the lamp more abundant than the general front light, and the effect control is more precise.
In addition, once the lamp is fixed, there is no need to climb the ladder to adjust the direction and angle of the lamp. The lighting engineer can quickly adjust the direction and angle of the lamp by controlling the XY axis, focusing and so on. Save time, manpower and material resources.
Experts predicted 10 years ago that the characteristics of LED technology determine that LED stage lights will gradually replace traditional lamps and become the new darling of the studio, stage and even the entire lighting industry. The emergence and development of LED front light will also be unstoppable! An energy-saving, convenient, bright, suitable for medium and large-scale performance front light is urgently needed for all stage lighting colleagues!
