Optionally, the LED emits light of the color, and emits light of intensity corresponding to the color.

Optionally, before the load measurement, it also includes:

Dividing the load range of the human body into multiple sections on average to obtain the load range; each of the load ranges corresponds to a determined load level, and the load levels corresponding to each of the load ranges are different;

Divide the difference between the maximum value and the minimum value of the load in the load range on average into multiple intervals to obtain the overflow interval, each overflow interval corresponds to the determined overflow level; each overflow interval The corresponding overflow levels are not the same;

The body weight includes human body weight and body weight. Specifically, the value of the body weight is equal to the sum of the value of the body weight and the value of the body weight. For example, if the body weight of a person is 70kg, and the body load is 10kg, then the body load is 80kg.

This embodiment takes eleven load levels as an example. Load levels are divided into eleven levels: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, and 10, and the corresponding load ranges (kg) are above 0, above 10, and above 20 , 30 and above, 40 and above, 50 and above, 60 and above, 70 and above, 80 and above, 90 and above, and 100 and above. For example, if the user's load is 5kg, it should be classified into the range above 0, and the corresponding load level is 0; 25kg should be classified into the range above 20, and the corresponding load level is 2. The resulting load range-load class correspondence table is shown in Table 1.

Load range G(kg) load class 0≤G<10 0 10≤G＜20 1 20≤G<30 2 30≤G<40 3 40≤G<50 4 50≤G＜60 5 60≤G＜70 6 70≤G＜80 7 80≤G＜90 8 90≤G<100 9 100≤G 10

Table 1

This embodiment takes ten overflow levels as an example. The difference (kg) between the maximum value and the minimum value in the corresponding load interval of each load class is 10, and the difference is divided into 10 overflow intervals on average. The overflow level is divided into ten levels of 0, 1, 2, 3, 4, 5, 6, 7, 8 and 9, and the corresponding overflow interval (kg) is divided into 0 and above, 1 and above, 2 and above, 3 and above, 4 and above, 5 and above, 6 and above, 7 and above, 8 and above, and 9 and above. If the user's load overflow is 1.5kg, it should be classified as 1 and above, and the corresponding overflow level is 1. The resulting overflow interval-overflow level correspondence table is shown in Table 2.

Overflow interval ΔG(kg) overflow level 0≤ΔG<1 0 1≤ΔG<2 1

2≤ΔG<3 2 3≤ΔG<4 3 4≤ΔG<5 4 5≤ΔG<6 5 6≤ΔG<7 6 7≤ΔG<8 7 8≤ΔG<9 8 9≤ΔG 9

Table 2

Optionally, in the correspondence between the loading levels and the luminous colors, the luminous colors corresponding to each of the loading levels are different. Eleven load levels correspond to eleven luminous colors. The luminous colors corresponding to the load levels of 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, and 10 are white, purple, blue, cyan, green, brown, yellow, orange, pink, Red and red. As the load increases, the color tone changes from cool to warm, and becomes more and more intense. The color of the carpet adopts a color different from the above-mentioned eleven kinds of luminescent colors, so that human eyes can distinguish them. The resulting load level-luminous color correspondence table is shown in Table 3.

table 3

Optionally, in the corresponding relationship between the overflow level and the luminous intensity, the luminous intensity corresponding to each overflow level is different. The overflow grades from 0 to 9 correspond to the intensity of 55%, 60%, 65%, 70%, 75%, 80%, 85%, 90%, 95% and 100%. The intensity here is a relative intensity, that is, an amount relative to the maximum intensity. 55% of maximum intensity is also bright enough. The formed overflow level-luminous intensity correspondence table is shown in Table 4.

overflow level light intensity(%) 0 55 1 60 2 65 3 70 4 75 5 80 6 85 7 90 8 95 9 100

Table 4

The luminescent color is integrated by the three primary colors of red, green and blue. The equation of the integrated luminous color of the three primary colors is F=x[R]+y[G]+z[B], where x[R], y[G] and z[B] represent the three primary colors of red, green and blue respectively of luminous intensity. The modulation method of the three primary colors adopts the PWM modulation method, and the PWM modulation has the characteristics of high color control precision. Use PWM to drive the three primary colors to control the brightness to achieve the required color ratio, so that the luminous color is the required color; use PWM to control the luminous intensity of the three primary colors synchronously and proportionally to the percentage of the maximum intensity determined by the overflow level-luminous intensity correspondence table , so that the luminous intensity of the LED is the required intensity. This allows the LED not only to emit a specific color of light, but also to maintain that color at a specific luminous intensity.
