Recently, Jin Luming and Gaopu, the world's leading professional LED lighting companies, held a strategic cooperation conference in Shenzhen. Jin Liuming announced that it has entered the high-end outdoor lighting field and adopted a high starting point, high investment and high value strategy to create revolutionary products. Use this as a strategic weapon to occupy the domestic market.
The street lamp released by Jin Luming adopts HOPE TM integrated solution, and the measured light value of the whole lamp is up to 130lm/W, which is the best for light efficiency and price. The street lamp adopts modular design to create a series of products, which can not only meet the large-scale production and supply of large-scale, but also simple installation scheme, which can be designed and constructed without professional lighting engineering company or street lamp enterprise. The foundation of application and popularization.
Optical solutions to create core strengths
The small light source characteristics of the LED chip can easily achieve accurate light distribution and secondary optics optimization design, accurately control the direction of the light, and distribute the light to the road to be illuminated to prevent light pollution and glare. Secondary optics is an important part of directly determining the output efficiency, distribution, uniformity and glare of LED street lamps. Green and environmentally-friendly urban road lighting requires LED street lights to produce rectangular light spots that cover the road, and light pollution to other places outside the road, such as residential buildings and buildings.
The spot of most high power white LEDs on the market today is circular. If the LED street light is not designed with secondary optics, then the spot on the road will be a “round cakeâ€. About 1â„2 of the spot will be scattered outside the road and wasted, and the middle of the spot will be compared. Bright, it will gradually darken around. After the lamp is installed on the road, a clear distribution of light and dark spots will be formed between the street lamps, causing visual fatigue to the driver and causing an accident. LED street lights in this case cannot be called "energy saving" and "green lighting".
Avoid glare In addition to the light source in the lighting design process, the light source is located within 30 degrees of the human eye level, but also consider the LED street light as a point source, the brightness is extremely large, generally the lamp cover is used to turn the light source into a scattering light source. The secondary optical design is an important technique for determining the light distribution curve, output light efficiency, uniformity, and glare index of LED street lamps. At present, LED street lights are basically equipped with a single lenslet, which looks like a bright spot. These bright spots are irritating to the human eye and cause ghosting and other problems.
At the press conference, Jin Luming displayed outdoor lighting products such as street lamps and floodlights from 40W to 200W. He also ambitiously released the next stage of street lighting development plan, which not only adopts the unique modular design of Jin Luming, but also applies the revolution. Slight light distribution design, using Sharp high-power integrated package chip, with CAMETA TM lens to form the world's first special optical system for street lamps, reasonable control of light distribution to make the spot rectangular, ensuring ideal road surface brightness and uniformity while making high power LED road lighting energy utilization is the ultimate, light distribution is designed for road lighting, in addition to illuminating the road itself, there is no light pollution to the surrounding environment. In addition, the problem of glare and ghosting of ordinary high-power LED street lamps is eliminated, glare, visual fatigue and line-of-sight interference caused by poor glare of ordinary high-power LED street lamps are eliminated, driving safety is improved, and traffic accidents are reduced.
The CAMETA TM lens array used in this optical system simultaneously acts as a concentrating and shielding device, avoids repeated waste of light, reduces light loss, and also reduces the weight of high-power LED street lamps, and simplifies the structure, allowing products More light and thin.
Jin Luming applied a unique light distribution technology on the street lamp, reasonably controlling the light distribution to make the spot appear rectangular, ensuring the ideal road surface brightness and uniformity, eliminating the glare of ordinary high-power LED street lights and making high-power LED road lights. The utilization rate is maximized and there is no light pollution.
Jin Luming first proposed the use of asymmetric free-form surfaces and free-form surface boundary fusion technology to design and process street lamp lenses. The light efficiency and uniformity far exceed the so-called “peanut†lens, and the series of lenses are designed and produced according to different scenes. Achieve precise light distribution. The street lamp ultra-high-order asymmetric free-form surface lens achieves accurate light distribution, ensuring road illumination uniformity and light utilization, and minimizing the zebra effect.
The lens has ultra-high uniformity and can be designed to be more than 85% for a specific scene. The obtained light distribution curve is optimized according to the actual road conditions. The curve is perfect in the direction of C0-C180, and the self-deflection angle in the C90-C270 direction can reach more than 15 degrees. In the specified range of use, the geometric utilization (the ratio of the required illumination area to the actual illumination area) can be increased to more than 80%.
Unique defocus free-form lens blending technology. The technology comprehensively balances the light efficiency and color characteristics of the luminaire, fully exploits the potential of the chip while ensuring color uniformity, and improves the overall lighting efficiency by 14%.
In addition, the large self-deflection angle enables the installation of low elevation angles of the luminaire. The lens is made of high quality optical grade PMMA material with small size and high light transmittance, up to 92%. With the "zero air gap" light path design concept. The light does not need to pass through any air medium before leaving the luminaire, effectively avoiding the loss caused by light entering and leaving the air medium, and improving the luminaire efficiency by 8%.
The optical system fully embodies the perfect combination of optical function and waterproof, dustproof and anti-sand sand, which completely abandons the separate waterproof, dustproof and sandproof cover required for ordinary LED street lamps, thereby further significantly improving the whole lamp output efficiency by 8%.
It is the above-mentioned advantages, especially the characteristics of ultra-high geometric utilization and ultra-high uniformity, which can save the number of LED light sources on the premise of achieving the same illumination on the road, thereby greatly reducing the manufacturing cost of LED lamps. Reduce energy costs in later use and make it more energy efficient.
Efficient heat dissipation guarantees longevity
The company and Harbin Institute of Technology jointly established the Institute of Thermal Conduction Technology, specializing in LED lamp cooling technology, and obtained a number of patented cooling technologies. Effectively reducing the junction temperature of the LED chip, greatly ensuring the reliability of the LED work, and at the same time further improving the luminous efficiency of the LED light flux by 5%.
The ultra-low thermal resistance technology on the complete heat transfer path from the chip to the heat sink is used to effectively reduce the junction temperature of the chip. From the heat sink of the LED chip to the heat transfer path of the external heat sink, the thermal conductivity of all materials is greater than 60W/mK;
At the same time, an ultra-short thermal path is adopted, and the heat conduction path from the LED chip to the heat-dissipating housing is greatly simplified by reducing unnecessary intermediate medium, and the temperature difference from the heat-dissipating column of the LED chip to the external heat sink is less than 12°, thereby ensuring The reliability of the LED itself works.
The unique modular heat dissipation structure enhances the heat dissipation. The HOPE TM street light is composed of a plurality of modules, and each module is independently cooled. The air gap between the modules can form a strong thermal convection, quickly taking away the heat of the module casing, and solving the problem of the traditional integral heat dissipation structure of "cool around, intermediate heat".
This innovative modular design can also be arbitrarily combined into products with different power and brightness requirements. Each module is an independent light source and can be interchanged. Local faults do not affect the normal operation of the entire luminaire, which is convenient for disassembly and maintenance, saving maintenance costs and making maintenance work very easy.
The innovation of heat conduction and heat dissipation technology also reduces the size and weight of the heat sink. At the same time, it is small in size, light in weight and high in stability. It can effectively reduce the wind resistance and reduce the load on the pole, which is safe and reliable. Taking 120W lamps as an example, the lamps produced by Jin Luming weigh less than 8 kilograms, while other companies produce 15 kilograms or even 20 kilograms, further reducing material costs.
Jinluoming professional LED street lamp adopts the combination of physical dustproof and chemical dustproof to realize the self-cleaning of the product: in the structural design, it ensures the large-area air permeable convection, and uses the small hole of the mask to block the large particle dust block; The surface uses special coating technology to reduce the surface polarity and surface energy of the surface of the radiator, reducing the probability of dust adsorption. Even if there is dirt, it will fall off when it is wet or rain. The heat and heat dissipation of the luminaire during long-term use is kept high, ensuring the reliability of the luminaire.
