At present, various existing intelligent lighting lamps are controlled by adjusting the properties of the lamps through a remote controller, a control panel, a mobile phone APP and other devices, namely, an adjusting object is a light source. According to the application, the illumination result of the target area is adjusted, namely, the adjusting object is the end point of the light, and the adjusting illumination is more in accordance with the illumination requirement than the adjusting brightness.
For example, a lamp has multi-level dimming, and the design of the lamp determines the appropriate scene for each level of brightness. However, there may be a large difference between the actual installation space and the expected space in the lamp design, so that the same adjustment setting cannot meet the requirement of the final ambient light effect. In this regard, the general practice of the lamps in the market is to mark the applicable area of the lamp, however, on one hand, the space with the same area is different in terms of shape, mounting position of the lamp, reflective surface property, etc., and on the other hand, the influence of factors such as different batches of lamps, service life, environmental property, etc. will cause the difference between the luminous performance of the lamp and the design, so that the final lighting effect cannot be guaranteed to meet the requirements.
The existing intelligent adjustment is mainly based on time, scene and current light conditions, corresponding adjustment commands which are already set are extracted in the background, actual calculation is not combined, and a final illumination effect is verified in a measurement mode. The user selects a preset scene or a preset mode, the lamp is adjusted to a preset light-emitting mode, and the ambient light is changed, but the user cannot know whether the brightness and the color temperature of the lighting lamp meet the objective requirement of the current use scene. When the existing lighting lamp is actively and manually adjusted, the brightness of the lamp changes, the brightness of the environment changes, and a user can keep the lamp in a certain lighting mode according to subjective experience, but can not judge whether the lamp meets the objective requirement of a use scene, wherein the objective requirement mainly refers to the limiting condition of each current building standard and lighting standard on the lighting quality of each scene.
