Problems solved by technology

[0003] At present, there are two types of evaluation methods for the spectral response of lighting photobiological effects. One is the response curve based on the inhibitory effect of melatonin. The evaluation of lighting scenes lacks immediacy, and at the same time, this method fails under low illumination conditions; the other is the spectral response curve based on pupil size changes. The change in the role of ipGRC is also the result of the joint action of ipRGC and cone cells and rod cells, that is, the visual and non-visual channels of illumination cannot be effectively and completely separated

Embodiment 1

[0037] Example 1: School classroom photobiological effect lighting, the classroom structure is five rows and ten columns, the window faces north, the B / P and equivalent photobiological effects in the classroom at different times are shown in Table 1.

[0038] Table 1 B / P and equivalent photobiological effects in classrooms at different time periods

[0039]

[0040] The B / P value in the natural lighting environment is close to that of 4000K~6500K fluorescent lamps. According to the adaptability of the human body to natural light, people feel the most comfortable in the natural light environment. According to the actual measurement, the B in the classroom at different times is shown in Table 1. / P and the equivalent photobiological effect, compare the contribution value of the photobiological effect with the natural light environment, and adjust the spectral composition and color temperature of the LED light source.

Abstract

The present invention discloses a LED health lighting evaluation method and an LED health lighting lamp based on a biological effect. The LED health lighting lamp comprises an LED light source, a driving power supply which is connected to the LED light source, a control device (3), an illuminance measurement module corrected by a spectral response function obtained based on physiological parameter change of a human body under an LED light source illuminance condition, a luminous flux measurement instrument formed by a data processing module, and a background brightness measurement module. The LED health lighting evaluation method and the LED health lighting lamp is characterized in that the LED light source with different spectral components is subjected to biological equivalence evaluation, firstly the B / P value of the LED light source with different spectral components are stored in the memory of the luminous flux measurement instrument, a photopic vision illuminance is measured, an equivalent illuminance is the product of a photopic vision illuminance value and the B / P value, and according to the biological lighting effect needs to be realized, the spectral, color temperature and brightness adjustment of the LED light source are carried out through driving the control device so as to satisfy different lighting needs.

Description

technical field [0001] The invention relates to a photobiological effect evaluation method, in particular to a photobiological effect-based LED health lighting evaluation method and an LED health lighting lamp. Background technique [0002] With the continuous development of lighting technology, human beings' requirements for lighting quality have evolved from clear, vivid and safe to the current requirements for health. Effectively evaluating the photobiological effect of the lighting site is beneficial to the formulation and improvement of lighting standards that are more in line with the needs of human life, and has certain theoretical and practical significance for promoting green lighting projects such as healthy lighting, comfortable lighting, and energy-saving lighting. [0003] At present, there are two types of evaluation methods for the spectral response of lighting photobiological effects. One is the response curve based on the inhibitory effect of melatonin. The...
