Currently the road mainly with high pressure sodium lighting, LED street lights not really replace it. In this regard, Liu Muqing said, from a technical perspective, LED compared with HPS, LED is better,as the whole lamp light efficiency, LED street lights can reach 100lm / W or more, while the high-pressure sodium lamps and even plus ballast, the most they can achieve 60-70lm / W, LED luminous efficiency has been significantly more than high-pressure sodium, and cost from the price point of view, LED is also not much higher than the high-pressure sodium lamps.
Although from the technical perspective and market price, LED street lights are not worse than high pressure sodium lamp, but its popularity is still a process. Specifically from the following three ways:
One, LED street light efficiency than high pressure sodium lamp, this is just for technical levels. In the market, LED industry is currently in the early development of enterprises with poor than good business, this part of the "poor students" will cause the market for LED street lights misunderstanding: "LED street light is not very good."
So, how to get people to recognize and accept the LED street lights still need a good process;
Second, with the LED era of accelerating development, enterprises have gradually realized the importance of product quality, and continuously to high-quality development, quality of the overall market will increase the flow of goods;
Third, the standardization problem. Traditional high pressure sodium lamp, it simply is a light bulb, ballast and lamp shell composed three sample parts, light bulbs are among the most vulnerable to bad parts, life is about 1-2 years, even if broken, replace it very convenient because it is standardized products that can replace any bulb manufacturers.
For LED street lights, which all manufacturers product specifications differently, the replacement or repair the product manufacturers need to get back with an indirect view, LED street lights become bound by the monopolistic enterprise products. Non-standard products are LED street lights on the road ahead of one of the biggest bottleneck, standardized criteria for the establishment of an urgent demand for industrial development.
