With the acceleration of urbanization, LED street lamps have already entered people's sights. Today, the streets of big cities, LED street lamps can be seen everywhere, it embellishes the city's night sky. However, it still has not been fully utilized. It is nothing more than its own limitations. In order to ensure that LED street lamps can play more roles in our lives, we should solve these problems in the future research production and promotion.

First: The shape and structure of the lamp. The appearance of traditional street lamps and lanterns is basically the same, and is generally divided into two parts: light source and electric appliance. However, due to the particularity of LED light sources and the different light distribution methods, the shape of LED street lamps and lanterns can be described as numerous. Many of these lamps and lanterns cannot have the same appearance. To meet the requirements of the operation, even some companies apply the outdoor street lamp to the indoor standard.

Second: There is a problem with the connection of LED lamps and lampposts. At present, almost all LED street lights are fixed by screws, and there are few hoop bolts. In this way, there are great hidden dangers for the safe operation of the lamps.

The limitations of LED street light itself restrict its development

Third: Replacement of lamp parts. LED street light components generally have LED chips, power supplies (drivers) and lamp housing parts. The fragile parts are mainly power supplies and chips. In general, LED luminaire chips are electronic radiators that cannot be replaced, and the power supply (drive) can be replaced. However, there are many products that are not convenient enough to replace the power supply (driver), and replacement is time-consuming.

It is well-known that the lifespan of LED lamps can now reach 30,000-50,000 hours. If the LED chip cannot be replaced, it means that replacing the entire lamp will also cause waste.

Fourth: The problem of the life of the power supply (driver). Power supply (driver) is a critical component of current LED lamps. At present, the market is generally only to ensure the quality of the LED chip, and the life of the power supply (driver) is another matter. General manufacturers promise to guarantee 2 years. This is ultimately due to the fact that the development of LED street lights has encountered a new bottleneck - the quality of the power supply (driver) is not guaranteed, and it restricts the development of LED street lamps.

LED street light saving effect. Theoretically saving electricity, but the actual application of LED street lights is not more efficient than high-pressure sodium lamps. Under the premise of lighting quality standards, high-pressure sodium lamp high-power lamps (250 ~ 400W) luminous efficiency, up to 130 ~ 140 1m / W. The high-power LED street lamp uses 1W LED tube, in theory, its light efficiency and high-pressure sodium lamp is similar, but consider the loss of ballast, lamp efficiency and the use of three factors such as the utilization of the track, comprehensive consideration, the current efficiency of LED than the high pressure sodium lamp Lower. The low-power LED street light (≤ 150W) is 10% more energy-efficient than the high-pressure sodium lamp.
