LED street lamp production and promotion in the future

Date: 2017-10-22 12:24:14    Views: 245

With the acceleration of the urbanization process, LED street lamps have already come into people"s vision. Nowadays, LED street lamps can be seen everywhere in the streets of big cities, and it adorns the night sky of the city. However, it is still not fully utilized, simply because of its own limitations. In order to ensure that LED street lamps can play more roles in our life, we should solve these problems in the future research, production and promotion

First: the shape and structure of lamps and lanterns. The traditional street lamp shape is basically the same, generally divided into two parts and electric light source, but due to the special nature of light and LED light source is different, so LED street lamp appearance is diverse, many of which appearance and can not meet the operation requirements, and even some enterprises are used in outdoor indoor standard street lamp.

Second: LED lamp and lamp pole connection problems. At present, almost all the LED street lamps are fixed by screws, and few are fixed by hoop bolts. So, there is a great hidden danger for the safe operation of lamps and lanterns.

The limitation of LED street lamp restricts its development

Third: the replacement of lamps and lanterns parts. LED street lamp parts generally have LED chip, power supply (driver) and lamp shell parts. The bad parts are power and chips. Generally speaking, the LED lamp chip can not be replaced, but the power supply (driver) can be replaced, however, there are many products in the replacement of the power supply (driver) is not convenient, replacement is too time-consuming.

As we all know, the life of LED lamps can reach 3 - 50 thousand hours now. If the LED chip cannot be replaced, that means replacing the entire lamp, and it can also cause waste.

Fourth is the life of the power supply (drive). The power supply (driver) is the key component of the LED lamps. Is currently on the market are generally only to ensure the quality of the LED chip, and the power of life is another matter (drive). General manufacturers promise to guarantee 2 years is good. This is due to the fact that the development of LED street lamps has encountered a new bottleneck - the quality of the power supply (drive) can not be guaranteed, which restricts the development of LED street lamps.

Power saving effect of LED street lamp. Theoretically, power saving, but the actual application of LED street lamp is not higher than the high pressure sodium lamp power saving. Under the premise of lighting quality standard, the luminous efficiency of high pressure sodium lamp high power lamp tube (250~400W) can reach 130~140 1m/W. The high-power LED street lamp for 1W LED tube, the theory of light efficiency and high pressure sodium lamp ballast, almost, but considering the loss of efficiency and the utilization rate of light lamps and other three factors into consideration, the LED ratio in the efficiency of low pressure sodium lamp. Small power LED lamp (150W) than the high pressure sodium lamp energy saving 10%.
