Downhill or closed LED lighting companies
Careful reflection on our smart lighting products, often only remote control functions and some communication functions, but basically no logical thinking and processing functions that are actually needed in various occasions. The practicality of these products is often not good, and the fun is not as good as video games, so it will inevitably die after a small wave. In China's lighting industry, some enterprises with certain scale and technically leading advantages have basically approached and caught up with international famous brands in the design, process and manufacturing technology of LED lighting products and lighting application design. It also has an obvious performance/price ratio advantage. However, the impetuous sentiment of the industry's eagerness and quick success has not passed through in-depth and meticulous demand research and has no technical features, and plagiarism with each other; the human cloud has caused serious homogenization competition. In the end, it should be that all-round competition has become a simple price competition. In the bidding for lighting projects, there is no minimum in the quotation, only a lower phenomenon. The result is that the loser is gradually eliminated, and the winner is also badly hurt. . 1, intelligent lighting, so-called smart bulbs - dimming + color, useful remote control; useful mobile phones through the telecommunications network remote control; also through the Internet remote control; Lin Lin, but at best a scientific and technological content of remote control lights, not smart Lighting Products. (I definitely don't mean to negate the meaning of these products.) Smart lights or smart lights: lighting products with sensors and communication functions and processing components. Most of the so-called smart products basically only have communication functions, and some only have the function of receiving commands in one direction. Basically, there is no sensor related to lighting, so the lighting system cannot sense the current situation of the lighting area, and there is no logic according to people's daily thinking. To process the perceived information and respond accordingly, these products cannot be called smart lighting products. Although the above products also have some applications, they are not suitable or even likely to be messed up in many occasions. For example, for the above products, when it is necessary to start the game at night, it often causes trouble because the remote controller cannot be found. In this case, the switch with a fixed position is more practical. When it is necessary to use a mobile phone to remotely control through a telecommunication network, it is impossible to implement a remote control due to a bad network. Real smart lighting should be able to set and react automatically according to the actual situation. For example, when the pressure sensor under the bed senses that the weight of the person is concentrated on the edge of the bed and the illumination is very dark, the way to turn on the night light to illuminate the toilet is automatically handled, instead of the switch or remote control that allows people to slap the black light. Intelligent lighting system: It is an adaptive lighting system. It is designed to be people-oriented and energy-saving. Lighting is implemented by smart lights and smart lights including natural light and control. Careful reflection on our smart lighting products, often only remote control functions and some communication functions, but basically no logical thinking and processing functions that are actually needed in various occasions. The practicality of these products is often not good, and the fun is not as good as video games, so it will inevitably die after a small wave. Smart Street Light: In a strict sense, it is just a multi-purpose garden light. Its functions are basically not inherently related, and its query function is affected by the respective government departments and cannot be supported by the government big data platform. So the ideal is full, and the reality is very skinny. Unless the government has big reforms. Special attention should also be paid to the anti-jamming and reliability problems of intelligent control systems (the example of Guangdong boss using iped to control household lights), otherwise it will cause inconvenient use to affect the reputation of intelligent lighting and even lead to safety accidents (smart confusion). In fact, intelligent lighting is not lacking in technology and means at present. What is lacking is the in-depth research and careful planning and implementation of innovative design solutions and products for lighting needs or potential needs, and the discovery and satisfaction of these needs are determined. Awkward craftsmanship. I think the direction and ideas of the supply-side reform proposed by the government come from actual needs and potential needs. 2, road lighting problems Not only to improve the lm / w of the lamps, but more important is to accurately allocate light according to the actual situation of the road, to achieve high utilization of light. The new standard of CJJ45 has clearly defined the brightness and brightness uniformity. However, in many places in China, attention is still paid only to illumination and illumination uniformity, but it is not noticed that the road of high-speed motor vehicles is more emphasized. Brightness uniformity. The zebra crossing of the road surface in Figure 1 is caused by insufficient brightness uniformity. For high-pressure sodium lamps, the self-illuminating angle is above 300 degrees, and the spatial light intensity distribution emitted by the reflector changes slowly, and the brightness uniformity only needs If there is no obvious zebra crossing above 0.6, the LED module mostly does not rely on the reflector for light distribution, so its light utilization rate is high, but the spatial distribution of light intensity changes rapidly, and the brightness uniformity is only close to 0.8. Obvious zebra crossing. Before and after the transformation of Shanghai Inner Ring Road, high-pressure sodium lamp illumination halo and stray light have a great impact on surrounding residential buildings, and LED lighting has almost no impact on surrounding residential buildings. Accurate light distribution and good cut-off are not only light pollution. And the photometric utilization rate is high. 3. The color rendering index is a measure of the effect of color rendering on road lighting. Under the illumination of artificial light source, the ability to reflect the color of it under natural illumination is very real, expressed by Ra. The color rendering index of the LED street lamp piloted in Shenda Road is about 70, and the road with the cross With high-pressure sodium lamps, the color rendering index is below 25. It is very obvious that standing at the intersection, the roadside greening clarity of LED street lighting is significantly better than that of high-pressure sodium lighting. This shows higher color rendering. The index can significantly improve the resolution of obstacles. Standing at the intersection, it can be observed very clearly that the roadside greening clarity of LED street lighting is obviously better than that of high-pressure sodium lighting. Both theory and practice have proved that the display is higher. The color index can significantly improve the resolution of the obstacles. 4. The road lighting adopts the light color 3000K or 5000K. It is impossible to hardly move the night indoor lighting to the road lighting. In addition, the higher color temperature of the LED lighting can also significantly improve the lighting performance. The era of high-pressure sodium lamps is popular because it is lighter than high-pressure mercury lamps and incandescent lamps, so it is widely used. Not only the color rendering index is low, but the road lighting of near-yellow light is also unreasonable, and it is not just natural. According to the natural law that people adapt to, indoor lighting should generally use a low color temperature light source at night to ensure a lower blue light component. Avoid affecting people's normal melatonin secretion at night. However, drivers who drive at night need to maintain high alertness. Appropriate high color temperature (such as 4000K ~ 5000K) will make drivers driving at night inhibit melatonin secretion, which is not easy to produce. The feeling of drowsiness is exactly what people who drive at night must keep.
