Solar LED lighting: market exploitation
The promotion of local government procurement of LED street lights from the pilot into a universal application, and often the order of a street light project on the ten thousand. ¡°Recently, Shandong Liaoyuan emitting solar LED lighting Business Unit Sales Director Cai Xingmao LED inside local governments to do the LED street light pilot project, an order of only a few hundred light, as many, but one thousand.
¡°Prairie fire luminous order of the first two months of this year had three times the same period last year, and each order is on more than ten thousand,¡± said Cai Xingmao hot extent of the current market can be attributed to the promotion of energy conservation projects in local government.
Recently, the Ministry of Finance Joint Development and Reform Commission, Ministry of Science and Technology announced on semiconductor lighting products, financial subsidies in 2012 to promote the project ¡°domestic public tender, products related to indoor lighting and road lighting. Following the LED high bay lighting financial subsidy policy was first introduced in 2011, released a new round of subsidies for the project tender.
However, a street light in Sichuan enterprise person in charge of the total but has its own view: ¡°suspected of over-exploitation of domestic solar LED lighting market.¡± The maturity of the LED lights is not enough large-scale promotion, too quickly to promote not bring technology advances, irrational investment.
¡°Streetlights biggest problem is the current product is not yet ripe, and is not suitable for large-scale promotion of brightness, illumination, and other technical indicators and sustainability is not a complete validation.¡± Zhang said.
Related statistics, the domestic LED lights in 2006 was only 40 or so, but as of now, LED lights enterprises has reached more than 1,400.
The split and integrated solar street lights are only different in structure?
In terms of the structure of solar street lights, there are two types: integrated and split type. Nowadays, split type solar street light whose each component is separated and installing is more flexible is more common. But now the integrated solar street lights are gradually becoming more and more popular.
An integrated solar led street light is to integrate and connect all the components together. It integrates solar panels, batteries, LED light sources, controllers, mounting brackets, etc. into one integrated street lamp. What are the differences between these two street lamps? Is it just a structural difference?
1) Modeling difference
Generally speaking, the integrated street lamp looks more compact and delicate, while the split street lamp is easy to give people a visual “pressure” and beautiful atmosphere.
2) Efficiency difference
Although all the components of the integrated street light are integrated together, which reduces the visual pressure, it also limits some functions. For example, under the same conditions, the larger the area of the solar panel is, then the greater the photoelectric conversion efficiency is.
Split-type street lights can be customized according to demand, while integrated street lights are not so flexible, and also need to consider the space occupied by other components, so there are limitations in efficiency.
3) Safety factor difference
Solar street lights are installed outdoors, and some people want to steal them. Whether the split street light battery is buried underground or on the pole, there is always a risk of theft.
For the integrated street light, if you want to steal the battery or something else, you can only remove the entire street lamp. This possibility is still very small, so the safety of the split street lamp is still higher.
