Description
Technical Field
The invention relates to the technical field of stage lighting lamps, in particular to a stage lighting source system.
Background
For a long time, stage lighting lamps and lanterns all adopt high-intensity gas discharge bubble as light source, it has obvious defect, in recent years, along with the development of light source technology, because LED has higher life, more favourable feature for environmental protection and better energy-conserving effect, so the world hopes to replace high-intensity gas discharge bubble with LED. However, the LED light source has a large light emitting area and low light power per unit area, so that the light efficiency of the actual use of the LED light source is low, and in order to improve the light source utilization rate, the F number of the subsequent optical imaging system can only be reduced, but the design difficulty and complexity of the subsequent optical imaging system are increased, so that the cost is greatly increased, and the LED light source cannot really replace the application of a high-intensity gas discharge bulb in a stage lighting fixture.
At present, a light source system of a stage lighting lamp adopts a bulb (high-intensity gas discharge bulb) or an LED (light emitting diode) as a light source, and the two light source systems have certain defects. The drawbacks of high-strength gas discharge bulbs are: 1. the polar distance of the high-intensity gas discharge bubble is long (about 6 mm), so that the light source is large in volume and heavy in whole. 2. In recent years, the polar distance of the high-intensity gas discharge bulb is short (1-2 mm), so that the matching performance of a light source and an optical imaging system is poor, and the integral imaging quality of a lamp and the distribution (namely the uniformity) of emergent light flux of the lamp are influenced; and the short gas discharge bubble of polar distance still leads to the cooling system to be difficult to design, and its cooling system is difficult to design, and then can lead to the improvement of luminous flux to be difficult and lead to the light decay rapidly, and life is too short, improves use cost greatly. 3. The display color is not rich, the color gamut is narrow, and the color is stiff. 4. The color temperature is not adjustable, and the universality is poor. 5. Contains harmful substances such as mercury and the like, and damages the environment due to frequent replacement.
Defects of the LED: 1. the displayed color is not rich and is dull. 2. The luminous efficiency of the LED lamp is low in practical use because the luminous area is large and the optical power per unit area is low. 3. If the utilization rate of the light source is improved, the F number of a subsequent optical imaging system can only be reduced, but the design difficulty and complexity of the subsequent optical imaging system are increased, and the cost is greatly increased. 4. The color temperature is not adjustable, and the universality is poor.
In order to make the light source system 1, the spot size at the focus of the light source system is fixed, and in practical use, pattern plates with different sizes are desired, so that the light source system cannot meet the requirement in the aspect; 2. the distance between the light-emitting surface of the bulb and the focus is fixed, and as the functions of the lamp are more and more abundant, more and more optical accessories need to be added, so that the rear intercept of the bulb is not enough; 3. the invention provides a stage lighting source system, which solves the problems that the aperture angle of light beams output by a bulb is fixed, the corresponding F number of a projection lens is very small, the complexity of the lens is high, and the cost is also improved.
