Background
The existing lamp panel mainly comprises a light source substrate and a plurality of LED lamp bead assemblies attached to the light source substrate, wherein each LED lamp bead assembly comprises an astigmatic lens and an LED lamp bead arranged in a concave hole of the astigmatic lens; because the directionality of LED light is strong, and the astigmatism angle is not big enough, so LED lamp pearl need diverge the illumination angle through astigmatic lens.
With the development of science and technology, personalized requirements appear on the color temperature adjustment of the LED lamp, for example, in hot summer, cold light can give people a comfortable feeling, and in cold winter, warm light can give people a warm effect. For this reason, various color temperature control IC chips, color temperature controllers, and the like are increasingly being introduced into the market. According to the structural feature and the colour temperature regulation technique of present lamp plate, the current colour temperature regulation and control process to LED light is as follows: the color temperature controller (or IC chip) firstly adjusts the color temperature of the light emitted by the LED lamp bead, the light with the adjusted color temperature is emitted out through the light-dispersing lens, and finally the light emitted by the light-dispersing lenses is mixed together to form the final light. As can be seen from the above, although the color temperature controller only makes one time of color temperature adjustment on the LED light, the LED light actually undergoes three times of color temperature adjustment, specifically:
firstly, adjusting the color temperature through a color temperature controller; namely, the adjustment is carried out by an electric control technology, and the adjustment process has higher requirements on technical control, so the manufacturing cost of the color temperature controller is higher, and the color temperature controller is difficult to popularize generally.
Second, adjust the color temperature by astigmatic lens filtering; the adjustment is passive and not easy to control, and often affects the distortion and instability of the final color temperature presentation.
Thirdly, mixing the light emitted by each light dispersing lens to form the final color temperature adjustment; because the color temperatures of the light emitted by the light scattering lenses are different, the mixed color temperature is larger in and larger than the color temperature designed in an ideal state, and therefore, the color temperature of each LED lamp bead needs to be continuously adjusted through a color temperature controller, which is the reason why the color temperature controller has high requirements on technical control and high manufacturing cost; in addition, in order to avoid the colour temperature that each astigmatic lens distributes to mix inhomogeneous, usually through optimizing the arrangement of LED lamp pearl subassembly at the light source base plate, will increase the area of light source base plate like this, lead to the lamp plate bulky, cost of manufacture high scheduling problem.
In summary, the passivity of the second and third color temperature adjustment is faced, so that the color temperature adjustment often has instability and non-uniformity. Therefore, how to optimize the structure of the LED lamp bead assembly and improve the stability and uniformity of color temperature adjustment becomes a hot topic of industrial research.
