The invention also provides an integrated double-mode mechanism for realizing the low-illumination solar simulator and the moon simulator by adopting the integrated double-mode ultra-wide light output adjusting range LED light source.
Description
Technical Field
The invention relates to the field of illumination design, in particular to an integrated dual-mode ultra-wide light output adjusting range LED light source which is used for forming an illumination environment with an ultra-wide illumination adjusting range, especially forming an illumination environment with an adjustable illumination range from an ultra-low illumination range to a conventional illumination range, and finally forming an LED light source product used in the illumination field or used for manufacturing a required test environment.
The invention also relates to an integrated double-mode mechanism for realizing the low-illumination solar simulator and the moon simulator by adopting the integrated double-mode ultra-wide light output regulation range LED light source.
Background
In the design of a situational lighting of an aircraft cabin, in order to increase the lighting comfort of the passengers, a smooth transition from a dark-vision environment to a bright-vision environment should be possible. In order to meet the requirements of different flight phases on lighting effects, it is necessary that the cabin lighting source can be continuously adjustable from a lower illumination level to a higher illumination level output.
In the research on the illumination comfort of the cockpit, the influence on the visual comfort and the working efficiency of a driver in the daytime flight light environment, the night flight light environment and the day and night light environment conversion process needs to be researched. In conducting relevant research regarding lighting comfort, there is also a need to be able to reproduce a continuously adjustable light environment from a lower light level to a higher light level output in a laboratory environment in order to test and study the impact of dynamic switching processes between ultra-low light level light environments and conventional light level light environments on humans.
Light sources commonly used in the civil aviation field include: of tungsten halogen lamps, fluorescent lamps, metal halide lamps, LED light sources, and the like, only LED light sources can support a wide range of light output adjustment. However, even with LED light sources, it is difficult to achieve a span of 10 from 0.01lx to 10000lx with a single light source6A wide range of orders of magnitude. However, if a single light source is used, on one hand, the adjustment accuracy is low in a low range of the light output value, and on the other hand, the design requirement on the driving circuit is very high, and a complex light modulation driving device and a high-power heat dissipation device and structure need to be equipped, so that the cost, the volume and the power of the light source are increased, and the use is inconvenient.
In view of the above technical problems, there are several schemes in the technical field:
for example, in technical document "development of all-weather dual-mode compatible illumination light source", an all-weather dual-mode compatible LED light source for aviation illumination is developed, and the LED light source has two working modes of visible light and infrared light. The dual mode adopted by the design is a visible light and infrared light dual mode which is completely different from a high illumination and low illumination dual mode.
In addition, in technical literature "design of three-segment dimming LED driving circuit", the three-segment dimming LED driving circuit chip designed in the literature successfully realizes switching of the operating state of a three-segment circuit controlled by a switching power supply, and output current can be used for adjusting color temperature or brightness through an external resistor. The design adopts a pure circuit driving mode to adjust the light output, and the mode is completely different from the mode of switching the light source module.
Furthermore, technical literature "a light source system with adjustable color temperature and illumination and an adjusting method thereof" discloses a light source system with adjustable color temperature and illumination, which comprises a light source and a computer for controlling the light source, wherein an upper computer software system for adjusting the color temperature and the illumination of the light source is arranged on the computer, an illumination detection sensor and a color temperature detection sensor are arranged in the light source, and the illumination detection sensor and the color temperature detection sensor are connected to the computer. The design adopts a sensor feedback mode to carry out self-stabilizing adjustment on the illumination of the light source.
In addition, technical document "a lamp box with adjustable illumination" discloses a lamp box with adjustable illumination. The lamp box adjusts the distance between each adjusting point on the adjusting frame and the mounting frame through the adjusting part, so that the aim of adjusting the illumination intensity is fulfilled.
For another example, technical document "a method and a driving circuit for adjusting the brightness of a high-stability and wide-range LED backlight" discloses a method and a driving circuit for adjusting the brightness of a high-stability and wide-range LED backlight. The MCU controller enables the LED driving circuit to enter a constant voltage mode or a constant current mode by controlling the protection voltage of the constant current IC, and meanwhile, a PWM pulse signal is output to control the LED brightness. Under the high-brightness backlight mode, the driving circuit enters a constant current mode, samples output current and keeps the output current in a high stable state through an automatic gain control closed loop. And in the low-brightness backlight mode, the driving circuit enters a constant-voltage mode, and drives the backlight circuit through DC-DC boosting to perform open-loop PWM switching control on brightness. Therefore, high-stability and wide-range brightness adjustment of the LED backlight is finally realized. The design is a dimming output circuit.
In view of the above, there is no integrated dual-mode LED light source with an ultra-wide light output adjustment range in the present technical field, which can avoid the adoption of a single light source to achieve adjustment of the ultra-wide light output range, so that under the condition of achieving the same effect, the adjustment precision is higher, the structure is simpler, the use is more convenient, and the LED light source has higher popularization and application value in experimental research and productization. Therefore, how to design an integrated dual-mode ultra-wide light output adjustment range LED light source that can meet the above requirements is a technical problem that needs to be solved.

In view of the above, the core technology of the present invention is as follows, different from the conventional LED light source: because the technical difficulty exists in using a single LED light source for a super-wide light output range, it is relatively easy to adopt two LED light sources to respectively realize two continuous light output ranges. Therefore, the invention designs the high-illumination light source and the low-illumination light source in one LED light source at the same time, and adjusts the specific light source used at present through the rotating mechanism, thereby realizing the continuous ultra-wide light output range in effect.
