Advantages of solar street light in the field of road lighting

Compared with the promotion of solar street light in the past few years, the current solar street light products are gradually mature, and the advantages of energy saving are prominent. In terms of heat dissipation and planning of solar street light, some new processing ideas are constantly emerging, and the problems of lifespan and light quality are also constantly being dealt with. Some solar street light companies have received some orders from abroad just after the Spring Festival. After a general consideration, we selectively took some orders and threw away some orders. We believe that it is more important to improve the quality of products now. This kind of idea is becoming a trend among solar street light enterprises. After experiencing the chaos of the market, we have put the key to continuously improving the quality of solar street light products this year. Industry experts call for improving lighting quality It has also initially attracted more attention from enterprises. After all, LED provides an opportunity to reshape the industry order for the future competition in the road lighting market. On the basis of a deep understanding of the market demand, it can wait for a larger market in the future. In terms of improving product and lighting quality, the company is still focusing on heat dissipation, product longevity, and light distribution. It is particularly worth mentioning that domestic solar street light has made new breakthroughs in heat dissipation planning. Shanghai Sansi Electronic Engineering Co., Ltd. launched a solar street light product with a plan two years ago - the upper and lower transparent plan, which can handle the heat dissipation problem very well. The relevant person in charge of Sansi told reporters that there are mainly two methods for heat dissipation planning in shopping malls, that is, die-casting, and all die-casting a shell is placed in harmony. One is that aluminum profiles etc. are attached to the discord, and the front is closed. And our product is a transparent design from top to bottom, which achieves a single heat dissipation, and the surface area is in direct contact with the air, which solves the problem of heat dissipation very well. A piece of glass is added to the traditional lamp surface. After lighting, only the marginal air will complete the convection. It is not very good if such a discordant diversion is added from the front. From a cooling point of view, this planning method is expected to become a development trend. The problem of light distribution is also being paid attention to by enterprises. Many people in the industry even believe that 'light distribution is the soul of solar street light'. A little fine-tuning of the internal angle of the seemingly simple plastic lens will lead to a significant difference in the application effect. It is believed that the in-depth treatment of these problems will definitely bring a new leap in product quality. Because the price sensitivity of street light market is lower than that of commercial lighting market, in terms of price, most solar street light manufacturers indicate that the price of solar street light in 2011 will be mainly affected by the price of chips. There is not much room for price reduction. More manufacturers will focus on deepening research and application technology and improving products this year. Now the solar street light technology is in the development stage, and there is huge room for improvement. Compared with traditional light sources, solar street light has the advantage of replacing other light sources in some road lighting areas (such as urban secondary roads, branch roads, blocks, village roads, etc.). According to media reports, the results of the solar street light demonstration program evaluation study conducted by the US Energy Administration in Oakland, California found that the average power used by each solar street light was 77.7 watts, which saved about 121 watts compared to the average power of HPS. 35%, based on 4,100 hours of operation a year, it is estimated that 178 kWh of electricity can be saved a year. Most of the products of European and American manufacturers are concentrated in the application planning of small roads, secondary roads, commercial blocks, and houses, and the goal is to replace high-pressure sodium lamps or metal halide lamps below 250W. Judging from the current solar street light technology and cost-effectiveness, solar street light has significant energy-saving advantages when applied to secondary trunk roads and branch roads below 10 meters. Assuming that the power of LED light source will exceed 150lm/W in the next 3-5 years, LED will develop rapidly in various fields of road lighting. Most experts believe that when the total operating cost of LED lamps is lower than that of traditional lighting, it can be replaced. Most people in the industry estimate that from the end of 2011 to the beginning of 2012, solar street light will be able to replace 150W high pressure sodium lamps, and from the end of 2012 to the beginning of 2013, solar street light will be able to replace 250W high pressure sodium lamps. , by 2015 solar street light will be able to replace 400W high pressure sodium lamp. Solar street light is different from traditional street lights in terms of light, color and lamp structure. Because our country is vast, the operating conditions and natural environment of different regions are different, and various requirements for solar street light will be put forward. We should promote the use of solar street light according to local conditions. It will play a positive role in the healthy development of the entire industry. Many experts pointed out that the future road lighting lamps do not necessarily have to be the method of existing lamps, but combine the characteristics of LED light sources, carry out innovative planning according to needs, better meet the lighting performance, and achieve energy-saving and beautiful lighting. effect.
