Problems solved by technology

However, this method has obvious defects. Since the installation position of the photosensitive sensor on the lamp is fixed, and the photosensitive sensor is facing away from the ambient light source and facing the ambient light source, the dimming effect may be quite different. On the other hand, whether the lamp is installed in the ceiling or protruding from the ceiling, the light perceived by the photosensitive sensor is also different. Difficulty perceiving ambient light

Embodiment

[0067] Such as figure 1 In order to realize the structural diagram of the system of the indoor LED lighting dimming method based on natural light in this embodiment, the system consists of three parts: Zigbee node module (including light group nodes and light collectors), TCP / IP gateway module (including Zigbee nodes and Ethernet access points), management system. The Zigbee nodes are divided into lamp control nodes, natural light intensity sampling nodes, Ethernet access gateway nodes and local controller nodes, and the natural light intensity sampling nodes are closely related to the present invention. Wide-area Ethernet and multiple local-area Zigbee networks constitute the topology of the lighting supervision system to realize data uplink and downlink transmission.

[0068] Such as figure 2 As shown, the indoor LED lighting dimming method based on natural light in this embodiment includes the following steps:

[0069] (1) Light intensity sampling of natural light sourc...

Abstract

The invention discloses an indoor LED lighting and dimming method according to natural lighting. First, a cube natural light intensity sampling node provided with photosensitive sensors on five faces is arranged on the inner side of a window of a building, and the weather condition at the moment is judged according to the light intensity of each face, wherein the light intensity is acquired by the natural light intensity sampling node; the radiation light intensity and the direct light intensity of a natural light source generated on an indoor work table top is calculated according to the weather condition, and the lighting intensity of the natural light on the indoor work table top is obtained; the working luminance degree of an indoor LED lamp is determined with reference to the lowest requirement of the human eyes for the natural lighting intensity. The indoor LED lighting and dimming method according to natural lighting achieves the aim that comfortable lighting is obtained in a working area of people, and the indoor LED lighting and dimming method has the advantages of being convenient and saving energy.

Description

technical field [0001] The invention relates to an indoor LED lighting dimming method, in particular to an indoor LED lighting dimming method based on natural light. Background technique [0002] With the development of society, lighting energy saving has gradually become the consensus of people. In addition to using high-efficiency light sources, reasonably controlling the output light intensity of light sources is also an important means of lighting energy saving without affecting people's lighting needs. Sunlight is the most suitable light source for human visual system. Rational use of natural light in indoor lighting can not only protect human eyesight, but also reduce power consumption. It has broad development prospects and good economic and social values. [0003] At present, there are two main types of domestic intelligent lighting, research and application of natural light in buildings: direct use method and indirect use method. The direct utilization method is to...
