Throughout the LED lighting market, technology maturity is getting higher and higher, and high-power LED lighting modules used in street lighting, commercial lighting, public lighting and other fields have become hot.
At present, in the field of high-power LED lighting module products, due to different LED luminous efficiency technologies, only about 15~25% of the input electrical energy will be converted into light energy, and the remaining 75~85% will be converted into thermal energy, conversion efficiency. not tall.
In this context, Liyang Co., Ltd. completed the research and development of high conversion efficiency module products in June 2016.
According to the relevant person in charge of Liyangguang Co., “Using this technology SMD 5050 light source, the initial power of the product is 30W, which can be driven to 60W (that is, the price of 30W can be purchased to 60W electrical parameters), which is super cost-effective.
At the same time, by simply replacing different secondary light distribution lenses, it is possible to assemble a module product suitable for different application scenarios, such as a street light module, a mining lamp module, a tunnel light module, and a high pole light module, which can save costs. And convenient and practical.
The innovation of the 5050 module is mainly reflected in three aspects.
1. Fin heat dissipation structure design
The product design adopts ultra-thin fin-type heat dissipation structure, does not collect heat, utilizes air convection and heat radiation effect, and quickly transfers heat into the surrounding cold air. At the same time, 5050 module products adopt high quality aluminum aluminum AL6063-T5 in material. The temperature rise is less than 28 degrees Celsius, which reduces the light decay and greatly extends the life of the module.
2. "Zero air gap" assembly process based on adaptive colloid technology
The product adopts optical grade PC material lens and silica gel filling technology, which effectively solves the phenomenon of large light decay (8%-10% light loss) in the secondary light distribution design process. With the “zero air gap†assembly process based on adaptive colloid technology, the 5050 module has a light loss of less than 2%.
3. Development and route layout of "Ultra Robust" LED light engine module technology
Using the SMD 5050 light source and the "Ultra Robust" module circuit design technology, no matter whether an open circuit or a short circuit fault occurs, it will not affect the current and voltage distribution of other LEDs, thus ensuring the normal illumination of the lamp bead and increasing the reliability of the module. .
Partial customer evaluation
1, 5050 module products have ultra-high uniformity UL>0.75, U0>0.45; also has more than 70% geometric utilization; easy to achieve small angle installation.
2, in terms of brightness, the effect of 5050 module products is very reassuring, especially for road lighting, the most intuitive feeling of the human eye is that the brightness of the road surface is not the illumination of the road surface. The application of the 5050 module product not only allows the road lighting to drive at night. It is safer and allows the driver to observe comfort and ease driving fatigue.
3, using 5050 module products, the overall lighting efficiency of 180LM / W, coupled with scientific secondary optics, replacing 250W traditional high-pressure sodium lamps only need 80 watts of LED products, replacing the traditional 400 watts of high-pressure sodium lamps only 130W LED products. More than 70% energy saving, very suitable for EMC projects.
