Description

Controllable Angle Modular LED Stage Light

technical field

The utility model relates to an indoor decorative lighting device, in particular to a modular LED stage light with controllable angle.

Background technique

With the improvement of people's living standards, the development of cultural and entertainment industries has higher and higher requirements for the construction of lighting large-scale opera houses and stages. Superb lighting interpretation technology can bring more shocking visual impact to people, and stage lighting design can better integrate with art while absorbing new technologies. Therefore, the demand for high-power stage lights has increased dramatically. As the representative of the new generation of lighting, LED lights have been favored for their advantages of green energy saving, environmental protection and long life, and are gradually being used in the field of stage lights. LED stage lights mainly include LED par lights, LED pattern effect lights, LED moving head lights, LED strobe lights, etc. At present, LED stage lights mainly have the following advantages:

1) Energy saving and high efficiency. Under the same light effect, several kilowatts of traditional stage lights can be replaced by hundreds of watts of LED stage lights, and because LEDs have less heat radiation, the efficiency of converting electrical energy into light energy is higher.

2) The colors are bright and rich. Light beams of various colors and brightness can be combined by red, green and blue primary color LEDs.

3) Long life. The lifespan of traditional stage lights such as general halogen tungsten lamps is only a few thousand hours at most, while the lifespan of LED stage lights can be as high as tens of thousands of hours.

4) Short response time. The response time of tungsten-halogen lamps is on the order of milliseconds, and that of LED lamps is on the order of nanoseconds.

Although LED lights have many advantages, there are still many unresolved problems on the way to replace traditional stage lights. Problems encountered in the development of LED stage lights at this stage:

1) The light concentrating problem of LED. It is a self-illuminating body. At present, the projected area of the LED light source is not far away. Although it has a strong light effect, the light and shadow effect formed by the LED point light is not as good as that of the metal halide lamp. LED products cannot illuminate the ideal height and distance.

2) The heat dissipation problem of LED products. Among the input power of LED high-power products, about 15% is converted into light energy, and 85% is converted into heat energy. High-power LED stage lights will inevitably generate a lot of heat. The heat dissipation problem needs to be solved urgently. Traditional LED lights are now equipped with an aluminum-based metal core printed circuit board (MCPCB) as a heat dissipation substrate. However, in the application of aluminum substrates, LED chips and substrates will fail due to thermal mismatch under high temperature conditions; in addition, the low insulation coefficient of aluminum substrate materials will cause certain safety hazards to LED lamps.

3) LED shape design is generally weak. At present, there is a single variety of LED lamps, mainly an optical structure: a square or circular light-emitting surface formed by a plurality of LEDs and focusing cups arranged on a plane to form an LED beam lamp. A large number of LED light sources are produced on a plane to form a plane illuminant that shines on the object. Except for a uniform light spot in the central area, the periphery is a soft and gradual aperture, forming an attenuation area from bright to dark, and it is difficult to form edges. Clear hard spot, it is more difficult to use imaging film to cut and produce various spots of different shapes. Such LED lamps can be used as floodlights or low-demand beam lights, but they must adapt to the different requirements of the stage performance on the beam, such as the hard spot where the edge is required to be clear, or where the light area is strict and the beam needs to be controlled by imaging and cutting. The occasion is difficult to apply.
