Problems solved by technology

[0009] First, the flexibility of the equipment is poor, and the irradiation range cannot be changed according to the specific environmental requirements;
[0010] Second, the current projection equipment is facing a big problem that the light utilization rate is low, which eventually leads to the problem of insufficient brightness.
The primary reason is that the display control components in the system are not active light-emitting components, and most of the light is not used

Abstract

The invention discloses a projection illuminating system which comprises a projection system, a control system and a reflection system, wherein the projection system is used for providing projection light of the projection illuminating system; the control system is used for controlling interconnection and communication between the systems; and the reflection system is used for converting the projection light emitted by the projection system into illuminating light in a specific range. According to the scheme disclosed by the invention, a projection principle is utilized to project basic light to the reflection system, a projection region is used as an illuminating light source and the reflected light is used for common illumination or special illumination. The projection illuminating system can provide the optimal flexibility for the illuminating environment and the high-efficiency light source and the projection system provide sufficient light utilizing efficiency for the projection illuminating system.

Description

technical field [0001] The invention belongs to the application field of semiconductor lighting, in particular to a projection lighting system. Background technique [0002] As a green and energy-saving fourth-generation lighting source in the 21st century, LED has gradually replaced traditional lighting sources with its advantages of pure color, high luminous efficiency, and low calorific value, and has been widely used in important fields such as lighting, decoration and display fields: [0003] First of all, in terms of lighting, especially the emergence of high-power LEDs has found a breakthrough for the application of indoor lighting and accelerated the application of LEDs in the field of indoor lighting. With the advancement of semiconductor optoelectronic materials and process technology and the improvement of the packaging structure of high-power white light LEDs, the luminous efficiency of white light LEDs has made great progress. CREE's white light power LED lumin...
