At present, in addition to the quality problems caused by poor heat dissipation and short life of the driving power supply, the conventional LED street lamps on the market also limit the insufficiency of maintenance and overhaul to the extent of the replacement of traditional street lamps by LED street lamps. 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.
Shanghai Sansi LED Ceramic Modular Street Light C0820-QR Series
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.

Variable Frequency AC Power Supplies
The VFP series AC Power Supplies are high precision, high efficiency, low THD adjustable AC power supplies that converts the input mains power through AC→DC→AC conversion, and gives a pure sine wave AC output with adjustable voltage & frequency within a certain range. Also known as Variable Frequency AC Power Source.
According to the difference in the number of output phases, it can be divided into single-phase and three-phase AC power supplies.
The output power of single-phase adjustable AC power supply ranges from 500VA to 200KVA, the output power of three-phase adjustable AC power supply ranges from 3KVA to 600KVA, the output voltage is divided into 0 ~ 150Vac, 150 ~ 300Vac, and the output frequency is adjustable from 45Hz to 70Hz with 50/60Hz fixed frequency output.
Through the friendly operation panel, you can read the output data such as output voltage, output current, output power, power factor, etc., providing accurate data records for your test, and can add RS485 interfaces as standard, following the MODBUS-RTU international communication protocol, which can realize remote control and operating status monitoring of the power supplies.
This series of adjustable AC Power Supplies have comprehensive protection functions, such as: over voltage, over current, over temperature and short circuit protections, which can protect the AC power supplies and DUT from damages. At present, it is mainly used for Various electrical appliance manufacturers conduct grid simulation tests on electrical appliances according to the voltage/frequency requirements of different countries. Imported electrical appliances are used for the domestic demand for variable voltage and frequency conversion, as well as various AC motors and AC transformers.
