LED intelligent lighting industry needs to pay attention to health lighting
Since the development of LEDs, the price war has been in full swing. When the price drops to a certain extent, if the price war continues, neither the industry nor the enterprise will be profitable. Therefore, the big situation will force LED to develop at a higher level, to create more value and performance of LED lighting, so that lighting is not only lighting, but intelligent control has become the choice to expand the value of LED. When the control of LED lighting is mentioned, the dimming and color temperature can be basically achieved at present, but the focus of intelligent control of LED lighting should not be just energy saving. Especially for the home, talking about energy-saving lighting, energy saving, power saving, is relatively primitive and superficial, to a certain extent is not conducive to the promotion and application of LED lighting in home lighting, more likely to be unprofitable. For home lighting, to achieve intelligent control of LED lighting, it is often necessary to purchase some dimming equipment, and the increase of these equipment will bring about the complexity of the circuit structure, and may also cause easy damage of the dimming system, which will affect The life of LED lighting products. As a result, even the energy and electricity bills saved by control are not enough to make up for the loss of LED lighting products. Moreover, unlike public lighting, for households, the proportion of electricity expenses in household financial expenditure is not high. Energy conservation is not the primary consideration for home lighting. If the family wants a bright, well-lit environment, it will not The lighting is blackened in order to save energy. Therefore, compared to energy saving, home lighting needs to emphasize healthy lighting, that is, lighting makes people feel comfortable, safe or have a feeling of leisure, there will be no pressure. The intelligent control of home lighting also needs to incorporate the concept of healthy lighting, and talk about energy saving in the case of health priority. At present, dimming and color grading are the basics of intelligent control of LED lighting, but how much brightness and how many color temperatures will make people feel the easiest and most comfortable. The discussion is not sufficient. Now it is just dimming, but it has not been done. To automatic dimming, the light automatically changes color temperature throughout the day according to the change of the sun. At the current level of technology, this kind of automatic dimming can be realized, but it depends on the degree of intention of the enterprise. Intelligent control is an important direction for creating the value of LED lighting in the future. If you want to do intelligent control, you need to do a good job in the general direction. You can make communication protocol regulations from the national perspective and height. For example, wireless control used for intelligent control, WiFi, and its signal format. This signal format is acceptable to everyone. Taking DALI as an example, the national level can specify the signal format, such as voltage, current amplitude, width, time difference, etc. Other details can be determined by the manufacturer. In the case of an LED lighting module, when the voltage and current of the driving power source are inconsistent with the voltage and current of the light emitting module, it is not that the light emitting module is burned or the overall system efficiency is lowered. An 8W or 10W lighting module, the voltage is 12V, some is 36V, the current is 300 mA, some is 240 mA, the national level is required to clear the interface between the lighting module and the drive current.
