New technology engine, "COB+glass lens" helps LED road lighting new future
Ten years ago, the country pushed for “ten cities and ten thousand lamps”. The application of LED street lamps was officially launched on a large scale. Traditional street lamps were gradually replaced by LED street lamps. Ten years later, with the development of smart cities, LED street lamps were an important entry point for smart cities. Point, usher in a new round of development opportunities.


In the past ten years, the market coverage of LED street lamps has increased year by year. The development of LED chip technology, LED packaging technology and LED drive power supply technology has been rapid. The theoretical life and performance of each component are relatively ideal. However, how to ensure the rapid development of LED street lamps The quality of street light products and meeting the new requirements for the development of the era of smart street lights are urgent and critical issues for road lighting.


However, the current outdoor high-power LED lighting market is often criticized: due to the uneven quality of LED street lamps, there are many products with short lifespan, large light attenuation, poor light distribution, and low efficiency, core components and lamps The quality misalignment between products. Among them, as the mainstream technology of LED street light products, the supply chain of SMD light sources and PC/PMMA lenses is mature and perfect, with the advantages of lower cost and low heat dissipation performance. Therefore, LED street light products mainly use SMD light sources + PC/PMMA lenses The main form of combination is about 90% of the market.


However, with the rapid development of LED chips and LED packaging technology, PC lenses are easily yellowed under ultraviolet radiation and high temperature, and the resulting light decay has far exceeded that of LED light sources. The corrosion resistance is poor, the material hardness is low, and the surface is prone to wind and sand. Scratches, easy to electrostatically attract dust in the air, and the light extraction rate of the lens gradually decrease. It is noticed by more professional manufacturers and end users.


On the other hand, glass lenses have the advantages of wide temperature range, ultraviolet resistance, strong corrosion resistance, and high surface finish. They have been recognized by more industry experts, manufacturing companies, and end users, and they believe that products in the field of outdoor lighting in the future More and more glass lenses will be used.

At present, LED road lighting is facing unprecedented development opportunities and challenges. We believe that the most urgent problems to be solved for LED street lighting products are the decay of the module table caused by the yellowing of PC/PMMA material lenses and poor outdoor weather resistance. Therefore, under the premise of satisfying the requirements of heat dissipation and pedestrian comfort on the surface brightness of the module, "COB+glass lens" is undoubtedly the most reliable form of LED street lamp module at this stage and in the future.


On this basis, with the continuous development and maturity of industry chain technology, such as the intensification and miniaturization of the function of the driving power supply, the industrialized light efficiency of LED chips continues to climb and approach the theoretical value, etc., Mingshuo Technology has developed from the industry and Considering the improvement of user experience, constantly proposing higher quality requirements and innovating more forward-looking street lamp forms, providing a lot of power and support for the development and growth of the industry, and providing city managers with the most convenient services and quality products, Let people enjoy a more low-carbon and comfortable living environment.


Nowadays, the new standardization scheme of "COB+optical glass lens" street lamp module has been shown to the world. In the future, the industry's technological development around low-carbon, intelligence, convenience, quality and safety will be worth looking forward to.




Through the function of graphene composite heat dissipation materials, the heat dissipation efficiency is improved by more than 30% from the three aspects of improving heat conduction, average temperature storage, and enhanced heat radiation. At the same time, combined with professional radiator structure design, the thermal density of the COB light source is systematically solved Concentrated problems, thereby taking advantage of the advantages of COB light sources, ensuring the service life, and greatly improving product performance.
