LED light and color mixing software system
spectral configurations can be simulated, enabling mass manufacturing of unique spectral customization to satisfy the saturation and fidelity application of specific and targeted objects and space scenes.
Simulate the white light effect after mixing according to the parameters of blue chip and phosphor, greatly reducing the sample customization cycle, while solving the problem of light color difference between different materials.
Thermal isolation phosphor coating technology
When the COB light source is working, both the phosphor and the silica gel will absorb a part of the blue light and convert it into heat. In addition, the heat capacity and thermal conductivity of the silica gel are relatively low, resulting in a sharp rise in the temperature of the fluorescent glue.
Adopting the centrifugal sedimentation method to reduce the thickness of the phosphor layer in the fluorescent glue, effectively solving the heat dissipation problem of the phosphor. The heat dissipation performance can be improved by 50%. Meanwhile, compared with the natural sedimentation process, it can save five times the time.
Full spectrum technology
Excited by multiple- wavelength blue LED chips, matched with phosphor, under the premise of completely no UV light, to simulate the full spectrum of halogen lamp effect, more fitting the solar spectrum.
Realizes a spectrally saturated transition from blue to yellow light, reduces the chance of green light overflow, and is closer to natural white light, in line with smoother full-spectrum applications;
It makes up for the lack of color performance from blue to green in traditional COB products, and can truly show the purity of the light color system represented by indigo blue and the natural purity of white.
Closer to the natural visual experience, more suitable for applications in the more demanding and professional color performance of high-end places.
Supplementing the 650nm long red light and 480nm long blue light band can promote the secretion of dopamine in the retina in the field of human health,which promotes the improvement of scleral elasticity, and inhibits the abnormal growth of the eye axis.
