Embodiment Construction
[0015] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0016] Such as figure 1 As shown, there are two kinds of warm white LEDs in this technology, the first one is the warm white LED3 with the central wavelength of light emission of the LED chip being 450 nanometers (nm), and the second one is the warm white light LED3 with the central wavelength of light emission of the LED chip being 470 nanometers (nm). White light LED5. The chip is coated with a mixture of yellow fluorescent powder, green fluorescent powder and silica gel. The content of green powder accounts for 5%-30% of the total powder, forming a warm white LED. Its correlated color temperature is controlled below 4000K, depending on the needs Depends on the blue light ratio. The lower the correlated color temperature, the smaller the proportion of blue light.
[0017] There are three kinds of red LEDs used in this example. The first ...
