Description
技术领域 Technical field
本发明涉及照明控制技术领域，特别涉及一种置于灯具内检测环境照度的方法及感应器。 The invention relates to the technical field of lighting control, in particular to a method and an inductor for detecting ambient illuminance in a lamp.
背景技术 Background technique
随着智能照明灯具大批量使用，越来越多的消费者希望得到一种更节能更人性化的产品，当外界光线超过一定照度值时灯具能够自动关闭，低于预设照度值时自动开启，或按照周围环境光的照度，自动地调整灯光的亮度，以实现灯光与自然光的互动，达到智能照明效果。因此灯具厂商希望将带有光感检测的感应器和灯具整合在一起内置式使用，这样既增加灯具智能控制，也保持灯具本身外观，还可以减少终端用户布线成本和安装难度。
With the large-scale use of intelligent lighting fixtures, more and more consumers hope to obtain a more energy-saving and more user-friendly product. When the external light exceeds a certain illumination value, the fixture can automatically turn off, and automatically turn on when the ambient illumination value is lower than the preset illumination value. Or, according to the illumination of the ambient light, automatically adjust the brightness of the light to achieve the interaction between the light and the natural light to achieve intelligent lighting effects. Therefore, the luminaire manufacturer hopes to integrate the sensor and luminaire with light detection into the built-in type, which not only increases the intelligent control of the luminaire, but also maintains the appearance of the luminaire itself, and also reduces the wiring cost and installation difficulty of the end user.
但是内置于灯具内的光电传感器在使用的时候除了接收到外界自然光谱外，还接收到灯具本身发出的人造光谱，对于灯具本身通过透光罩发出或反射的人造光谱中可见光的强度远远大于感应器周边自然光谱中可见光的强度，而且灯具本身发出的人造光谱中非可见光照度值，也会随着色温高低而变化，光源色温越低，灯具本身发出的非可见光照度值越大。这样内置于灯具内的感应器，通过普通光感检测方法就不能有效准确的检测传感器周边环境自然光的强度，因此也就无法真正根据自然光的强度实现灯具的亮度控制和关断控制。目前市场上大多数内置于灯具内的感应器都没有检测计算灯具本身的灯光照度值，当环境自然光开启阀值低于预设照度值时，比如黎明，此时有人经过触发灯具负载亮灯，由于亮灯期间无法检测真实的自然光照度，延时时间内不断有人经过感应时，就会不断刷新延时时间一直亮灯，即使外界自然光很亮时，负载灯也关不断，这样一来就会浪费能源。针对该问题和实际需求，大家一般采用灯具与传感器分开设置的方法，如将光传感器通过引线引出的方案，让光传感器远离灯具本身外置式使用，来达到只采集自然光的效果，这种方案对灯具尺寸及安装结构需重新设计定制，而且影响灯具本身外观整体性，因此难以大批量推广，且成本高。
However, in addition to receiving the natural spectrum of the outside world, the photoelectric sensor built in the luminaire receives the artificial spectrum emitted by the luminaire itself, and the intensity of visible light in the artificial spectrum emitted or reflected by the luminaire itself through the translucent cover is much greater than The intensity of visible light in the natural spectrum around the sensor, and the invisible illuminance value of the artificial spectrum emitted by the lamp itself will also change with the color temperature. The lower the color temperature of the light source, the larger the non-visible light value emitted by the lamp itself. The inductor built in the lamp can not effectively and accurately detect the natural light intensity of the surrounding environment of the sensor by the ordinary light sensing method, and therefore can not truly realize the brightness control and the turn-off control of the lamp according to the intensity of the natural light. At present, most of the sensors built into the luminaire on the market do not detect the illuminance value of the lamp itself. When the ambient natural light opening threshold is lower than the preset illuminance value, such as dawn, someone flashes the light through the trigger lamp. Since the real natural illuminance cannot be detected during the lighting period, when the person is inductive during the delay time, the delay time will be constantly lit, even if the natural light is very bright, the load lamp will be turned off continuously, so that Waste energy. In response to this problem and actual needs, we generally use a method in which the luminaire and the sensor are separately arranged, such as a scheme in which the optical sensor is led out through the lead, and the optical sensor is used away from the external use of the luminaire to achieve the effect of collecting only natural light. The size and installation structure of the luminaire need to be redesigned and customized, and it affects the overall appearance of the luminaire itself, so it is difficult to promote in large quantities and the cost is high.

下面结合附图对本发明的具体实施方式作进一步说明。在此需要说明的是，对于这些实施方式的说明用于帮助理解本发明，但并不构成对本发明的限定。此外，下面所描述的本发明各个实施方式中所涉及的技术特征只要彼此之间未构成冲突就可以相互组合。
The specific embodiments of the present invention are further described below in conjunction with the accompanying drawings. It is to be noted that the description of the embodiments is intended to facilitate the understanding of the invention, but is not intended to limit the invention. Further, the technical features involved in the various embodiments of the present invention described below may be combined with each other as long as they do not constitute a conflict with each other.
本发明的原理说明： The principle of the invention illustrates:
参考附图1，其中是太阳光不同波长光谱对应的放射能量分布图，可以看出太阳自然光谱中可见光比非可见光放射能力强,也就是自然光谱中能量最为集中的是可见光部分，现有光感检测方法都选择检测能量最为集中的可见光部分或至少包含可见光部分，优点是低端照度分辨率高，而灯具人造光谱的目的是照明，因此灯具人造光谱也必定是选择在能量最为集中的可见光光谱波段以实现效率最大化，所以缺点是亮灯时人造光谱对内置于灯具内可见光传感器的干扰太强，很容易达到可见光光感检测的饱和值而分辨不出自然光谱的变化，也就不能准确地关断灯具。
Referring to Figure 1, which is a radiation energy distribution map corresponding to different wavelengths of sunlight, it can be seen that visible light in the natural spectrum of the sun is stronger than non-visible radiation, that is, the most concentrated energy in the natural spectrum is the visible light portion, and the existing light. The sensing method selects the visible light portion with the most concentrated energy or at least the visible light portion. The advantage is that the low-end illumination resolution is high, and the purpose of the artificial spectrum of the lamp is illumination. Therefore, the artificial spectrum of the lamp must also select the visible light with the most concentrated energy. The spectral band is used to maximize efficiency, so the disadvantage is that the artificial spectrum is too strong to interfere with the visible light sensor built in the lamp when lighting, and it is easy to reach the saturation value of the visible light detection without distinguishing the natural spectrum change. Turn off the luminaire accurately.
通过测试大量不同功率和色温的人造光源灯具发现，人造光源灯具非可见红外光谱能量会随着色温高低而变化，散热功率越大，光源色温越低，灯具本身发出的非可见红外光谱照度值越大。
但灯具本身的非可见 红外光谱的 灯光值能量 没达到非可见光光感检测的饱和值，所以可以通过软件采样和算法扣除灯具本身的非可见红外光谱照度值，就可得到真正
自然光谱中非可见红外光谱的照度值。同时本发明 根据
太阳自然光谱中可见光和非可见光的光谱能量昼夜变化趋势相同的特性，通过非可见光检测方法实现灯具负载随自然光谱能量升高而关断控制。所以采用非可见光检测方法，优点是
亮灯时人造光谱对内置于灯具内非可见光传感器的干扰相对较弱。 缺点是 低端照度分辨率低，不能准确地 实现灯具负载随自然光谱能量变低而开启 灯具。
By testing a large number of artificial light source lamps with different power and color temperature, it is found that the non-visible infrared spectrum energy of the artificial light source lamp changes with the color temperature. The higher the heat dissipation power, the lower the color temperature of the light source, and the more the non-visible infrared spectrum illuminance value emitted by the lamp itself Big.
However, the energy value of the non-visible infrared spectrum of the luminaire itself does not reach the saturation value of the non-visible light sensation detection, so the non-visible infrared illuminance value of the luminaire itself can be deducted by software sampling and algorithm, and the real value can be obtained.
The illuminance value of the invisible infrared spectrum in the natural spectrum. At the same time the invention is based
The characteristics of the diurnal variation of the visible and non-visible spectral energy in the natural spectrum of the sun are the same. The non-visible light detection method is used to control the lamp load to turn off with the increase of the natural spectral energy. So using non-visible light detection methods, the advantage is
The artificial spectrum at the time of lighting is relatively weak to the non-visible light sensor built into the luminaire. The disadvantage is that the low-end illumination resolution is low and the lamp load cannot be accurately turned on as the natural spectral energy becomes lower.

Use the PD2 non-visible light detection module to obtain the non-visible ambient illuminance value 'LuxA' when the luminaire is OFF, turn on the luminaire to T2 brightness, and use the PD2 non-visible light detection module to obtain the 'environment and luminaire' mixed non-visible illuminance value 'LuxB', and calculate The invisible illuminance value of the luminaire at Lux brightness is LuxLightT2=LuxB-LuxA. Turn on the luminaire to T1 brightness, use the PD2 non-visible light detection module to obtain the 'environment and luminaire' mixed non-visible LuxC, and calculate the non-visible illuminance value of the luminaire when the T1 brightness is LuxLightT1=LuxC-LuxA. Then use the following formula to calculate the turn-off threshold for turning off the lamp load:
LuxOffT1=(LuxSetting+LuxOffSet+LuxLightT1)* k ； LuxOffT1=(LuxSetting+LuxOffSet+LuxLightT1)* k ;
