Say goodbye to integrated design modular light source to solve LED street lamp maintenance problems

LED Lighting Reuters Currently, the market of the conventional LED lights except for the presence of poor heat dissipation, drive power quality problems caused by short life than, inconveniences, maintenance and repairs are also limits to fully replace the traditional LED street lights to a certain extent . Conventional LED street lamps use an integrated integrated structure. If some of the LED light sources are damaged, the site cannot be replaced. Only the lamps can be replaced or returned to the factory for repair, which wastes resources and takes time and effort. In order to solve the above problems, LED street lights using modular light sources are used for transportation.

What is a modular street light LED street light?

The modularization of LED street light refers to the integration of several LED light sources in the LED street light into a module integrating light distribution, heat dissipation and IP dustproof and waterproof level. One lamp is composed of several modules, not the same as before. Install all LED sources in one fixture. The LED street light fixture of the whole modular light source is composed of three components, one is the base of the lamp, the other is the light source module, and the third is the driver.

The base of the lamp is used for fixing and carrying the light source module with a simple protection function; the light source module is a module integrating light distribution, heat dissipation and protection functions, and is a core part of the lamp; the driver provides energy and can Placed in the luminaire, it can also be separated under the pole.

What are the advantages of modular LED street lights?

1. The modular design of LED street lights is convenient for maintenance. If the drive is broken, change the drive. If the LED light source module is damaged, replace the damaged module. If the life of the LED light source expires or the product is replaced in the future, you only need to replace the components, no need to replace the whole lamp; The weight of the module is lower than the weight of the whole lamp, and the disassembly is convenient. If the LED lamp bead is damaged, the whole lamp is not required to be disassembled and repaired, and only the corresponding LED module needs to be repaired or replaced. In this way, the LED street light can be quickly maintained on site, and most of the components can be recycled, effectively extending the life cycle of the LED street light.

2. The modular design of the LED street lamp can also effectively solve the problems of heat dissipation, light efficiency and life of the power LED device module. On the one hand, there are ventilation holes between the module and the module, which is conducive to air convection heat dissipation and automatic cleaning of the lamps; on the other hand, by modifying the structure of the lamp body and the arrangement of components, the concentrated heat dissipation is changed to each module pixel independent heat dissipation, no The conduction heat resistance of the insulation layer, the heat generated by each module can be dissipated in time, and the heat dissipation is more effective and sufficient. In this way, the LED road light decay can be greatly reduced, the LED road lighting effect is effectively improved, and the service life of the LED lamp is guaranteed.

The modular development process of LED street lamps

Although the modularization of LED street lamps has many benefits, at present, there are technical obstacles in many key links such as heat dissipation, waterproofing, light distribution, free replacement of components, and adaptation to any sodium lamp housing, which hinders the modularization of LED street lamps. form.

In order to promote the modularization process of LED street lamps, the National Science and Technology Support Program “Semiconductor Lighting Application System Integration and Demonstration” key project specifically deployed high-reliability and modular LED industrialization technologies. The research content includes the structure of high-power LED street lamps, and the development of LED streetlight products with modularization of light source, interface standardization, serialization of specifications and simple operation.

In addition, the modular “high-power luminaire design” is also an important part of the national “863” project undertaken by Shanghai Sansi – standardization, modular LED road lighting and intelligent control system development and demonstration. Shanghai Sansi LED Ceramic Modular Street Light C0820-QR series is born out of the "863" project results. This series of LED street lamps adopts Sansi's own patented high-power LED lighting unit. The standard module is matched with unique lens design, which is convenient for large-scale production and installation of lamps. It is simpler, effectively reduces the maintenance cost of the later period, and greatly improves the heat dissipation efficiency of the high-power LED lighting module. The life and maintenance efficiency of the LED street lamp have been qualitatively improved and leapfrogged.

LED ceramic modular street light C0820-QR series features

First of all, in terms of heat dissipation performance, Shanghai Sansi has developed a ceramic heat sink and honeycomb convection heat dissipation technology with completely independent intellectual property rights. This technology was selected as the national key energy-saving low-carbon technology promotion catalogue in 2015. These two patented technologies are applied to C0820- After the QR modular street lamp, there is no non-ferrous metal, and the independent pixels disperse heat. On the one hand, it fundamentally guarantees safety and eliminates high-voltage leakage; on the other hand, it completely solves the world problem that the temperature is too high and affects the LED road light decay and life. .

Secondly, in terms of waterproof performance, Shanghai Sansi C0820-QR modular street light adopts light source COB encapsulation mode, meets the standard interface requirements of CSA016, has waterproof joint wire, and adopts self-patented plug-in installation, no cable exposed. The waterproof problem of the light source is completely solved. Since the independent light source can be fixed on the heat sink in various ways, the patented technology can also adjust the illumination angle of each independent light source according to actual needs, and the power of the light source can be adjusted as needed to make the LED street light The light source is completely modular and easy to maintain and replace.

Third, in other structures, Shanghai Sansi has designed the power supply, driver and heat sink of the C0820-QR modular street lamp into a modular structure that can be independently installed and disassembled, and the compatible angle of the same housing is adjustable and not adjustable. The function and saving a lot of replacement costs have great practical significance for urban street lighting renovation.

In addition, Shanghai Sansi C0820-QR modular street lamp is widely used in road lighting field due to its high luminous efficiency and low light decay. Its energy consumption can be reduced by more than 50% compared with traditional light source. Moreover, the C0820-QR street lamp uses optical components of equal brightness to design, and the road surface illumination is more uniform than the illumination design method such as LED.

Uniform illumination of the road surface, no “zebra crossing”, uneven illumination of the road surface, zebra crossing

In addition, the C0820-QR modular street light also incorporates a light-sensitive sensor, which can realize the function of automatically switching lights according to the ambient illumination. With the intelligent control system independently developed by Sansi, it can also realize multi-level dimming and remote monitoring of LED road lights. Management, to achieve secondary energy savings, to maximize energy savings in road lighting.

At present, Shanghai Sansi C0820-QR modular street lamp has been widely used in road lighting fields such as express roads, trunk roads, secondary trunk roads and branch roads due to its high luminous efficiency and low light attenuation.
