Detailed Description
The conception, the specific structure and the technical effects of the present invention will be clearly and completely described in the following with reference to the embodiments and the accompanying drawings, so as to fully understand the objects, the features and the effects of the present invention. The technical characteristics in the invention can be interactively combined to form a new embodiment on the premise of not conflicting with each other.
Referring to fig. 1, the optimization method for adapting the power of a multi-path light mixing source to the power of a power supply is used for optimizing the adaptation relationship between two or more paths of light mixing sources and the power of the power supply so that the power of the power supply can be fully utilized, and sequentially comprises the following steps:
step S1, collecting the power of each path of light source and the corresponding luminous flux data, and obtaining the relation data of the luminous flux and the power of each path of light source after processing;
step S2, inputting a target color temperature value of the mixed light source;
step S3, calculating the ratio of the luminous flux of each light source to the maximum luminous flux of each light source according to the target color temperature value;
step S4, calculating the power corresponding to each path of light source according to the ratio of the luminous flux of each path of light source to the maximum luminous flux and the relation data of the luminous flux and the power;
step S5, judging whether the power of any path of light source reaches the rated power of the path of light source and the sum of the powers of all paths of light sources does not exceed the rated power of the power supply, or whether the sum of the powers of all paths of light sources reaches the rated power of the power supply and the power of any path of light source does not exceed the rated power of the path of light source; if the determination result is negative, performing step S6, and if the determination result is positive, performing step S7;
step S6, proportionally adjusting the ratio of the luminous flux of each light source to the maximum luminous flux of each light source, and returning to step S4;
and step S7, outputting the power of each light source.
In step S1 of the above embodiment, when acquiring the power of each path of light source and the corresponding light flux data, the power of the light source is divided into N equal parts from 0 to the maximum value, and corresponding N groups of data are acquired, where the larger the N value is, the more the acquired data is, and the greater the difficulty is, but the more the relationship data between the light flux and the power obtained after the final processing is, the more accurate the relationship data is. The value of N can be selected according to actual needs, and is generally not lower than 100, preferably 255, so as to obtain a better balance between the difficulty of acquisition and the accuracy of data.
In practical application, the power of each light source and the corresponding luminous flux data collected in step S1 are normalized to obtain a normalized list of the relationship between the luminous flux and the power. And the data is normalized, so that the standardized management and search of the data are facilitated.
In step S3 of the above embodiment, the ratio of the luminous flux of each light source to the maximum luminous flux of each light source can be calculated by the color temperature value according to the light mixing superposition principle and the geometric characteristics of the color coordinates by using the method in the prior art.
The purpose of step S4 is to obtain the power corresponding to each light source, and to determine the power in step S5. After the relation data of luminous flux and power is normalized, the power is as follows: the ratio of the luminous flux of each path of light source to the maximum luminous flux of each path of light source is calculated by comparing the normalized list; if the data is not normalized and the specific data of the luminous flux is still reserved, the data can be obtained by calculating the ratio of the luminous flux of each path of light source to the maximum luminous flux, the maximum luminous flux data in the relational data of the luminous flux and the power of each path of light source and the relational data of the luminous flux and the power of the light source.
Of course, in the second calculation method, the maximum luminous flux of each light source may also be multiplied by the same percentage to calculate the corresponding power, and the power is correspondingly used as the initial value for the comparison in the next step. The percentage is generally 100%, 90%, 80%, 70%, 60% or 50%, preferably 100%, and the luminous flux is the maximum luminous flux of each light source, which is helpful to reduce the subsequent judgment and comparison calculation amount.
In step S6 of the above embodiment, the light fluxes of the light sources are adjusted to increase or decrease the light fluxes at the same ratio, and the light flux ratios of the light sources are kept consistent when the light fluxes are adjusted at equal ratios. The specific adjustment steps are as follows:
if the power of each path of light source is lower than the rated power of the path of light source and the sum of the powers of the paths of light sources is lower than the rated power of the power supply, increasing the ratio of the luminous flux of each path of light source to the maximum luminous flux of each path of light source; and if the power of any path of light source is higher than the rated power of the path of light source or the sum of the powers of all paths of light sources is higher than the rated power of the power supply, the ratio of the luminous flux of all paths of light sources to the maximum luminous flux is reduced. In practical application, the increase or decrease of the ratio adopts a binary search method, so that the required numerical value can be conveniently and quickly obtained.
In practical applications, in the determination process of step S5, it is difficult to make the power of one light source completely reach the rated power of the light source or make the sum of the powers of the light sources completely reach the rated power of the power supply, so according to the conventional method, a threshold is set for both the rated power of each light source and the rated power of the power supply, and the threshold is preferably one thousandth of the target value. As described above, the condition is determined to be reached as long as the power data to be determined falls within the threshold.
When the multi-path light mixing light source is used, the relationship between the luminous flux and the power supply power of each path of light source is roughly as shown in fig. 2: the actual relationship curve is shown as a solid line in fig. 2, and is a curve that is substantially convex downward. However, in the prior art, for convenience of processing, the approximation is processed into a linear relationship, such as a dashed line shown in fig. 2, in this processing manner, at a certain luminous flux, the actual power supply power of the power supply is lower than the set power, so that the power supply power is not fully utilized. The invention acquires the actual relation curve of the luminous flux and the power supply power by acquiring the specific data of the luminous flux and the power supply power, and provides a data basis for the adjustment of the luminous flux. The luminous flux ratio and the corresponding power are sequentially obtained from the target color temperature value, and after logical judgment and adjustment are carried out, the power of at least one path of light source reaches the rated power of the path, or the sum of the powers of all paths of light sources reaches the rated power of the power supply, so that the power of the power supply can be fully utilized, and the brightness of the whole lamp is further improved.
It should be noted that the above-mentioned embodiments are only used for further illustration of the present invention, and should not be construed as limiting the scope of the present invention, and if the present technology is simply modified, the objects of the present invention can be achieved by substantially the same means, and all of the objects should fall within the scope of the present invention.
