Still further, the modulation control module 13 includes an inertia measurement component 131, and a driving processor 132 connected to the inertia measurement component 131; the inertia measuring assembly 131 can perform multi-axial measurement on the linear acceleration value of the main body 11 during the lifting and moving process to calculate the lifting angle and moving speed of the main body 11, wherein the inertia measurement assembly 131 may be an accelerometer in this embodiment, the inertia measurement assembly 131 can perform multi-axial measurement for the linear acceleration value of the lifting and moving of the body 11, that is, in the present embodiment, when the three axial directions of x, y, z, etc. are used to calculate the theta values such as the lifting angle and the moving speed of the main body 11, that is, when one side of the main body 11 is used as the reference point to move up, down, left, and right, the inertia measuring unit 131 measures the moment the body 11 moves, and calculates according to the measured distance, angle, etc., the formula for measuring the moving and lifting angle of the body 11 by the inertia measuring assembly 131 is calculated as follows:

in the formula, the ratio of the total of the components,

θ: is the lifting angle of the body 11.

A_x: is the linear acceleration value of the x axis.

Furthermore, the driving processor 132 can generate a driving power to link to the light source module 12 to generate a light emitting state, and the driving processor 132 stores a driving memory with moving, lifting and other angles based on three axial directions of x, y, z and the like, so that the driving processor 132 analyzes and compares the information connected to the inertia measurement component 131 with the memory stored therein, and adjusts the display change of the light emitting linking the light source module 12 according to the value measured by the inertia measurement component 131, and the light emitting display can be set to be a display from weak to strong according to the use mode, or a gradual slow, medium and fast flashing mode, and certainly can combine two light emitting display modes into one and the same display mode for use, no matter what kind of display mode is described above, the light display strength is explained in this embodiment, that is, for example, the settings stored in the memory may be: in the angle θ of the lifting (moving), 0 degree is set as the light display of 30% for the light source module 12, 45 degrees is set as the light display of 60%, and 90 degrees is set as the light display of 100%, as can be seen from the foregoing, the driving processor 132 can effectively and reliably modulate and control the light source module 12 to accurately display the required light display by measuring and calculating the lifting angle through the inertia measurement component 131, and the calculation formulas can also be applied to the left and right swinging movement angles, which can also produce the same display effect.

Referring to fig. 2 to 3-2, the display device 1 with the body 11 in the form of a light stick can be a game article or an article with reminding and warning functions, which will be described below by way of example, so that the light stick type display device 1 with a set light emitting display mode is activated for use, that is, when a user holds one side of the body 11 and starts at a certain position, the light source module 12 will display 30% light emitting display through the body 11 with high light transmittance by setting the activated position to 0 degree, and when the body 11 is waved, the inertia measurement component 131 will measure the rising and falling angle and moving speed at the moment when the body 11 is moved, and the measured value is connected to the driving processor 132 to compare and analyze with the memory stored therein, and immediately link to adjust the light source module 12 to display the light emitting change, the outward light display state of the light source module 12 is improved from 30% to 100% to form light display change, so that the outward display of the light source module 12 is different with different moving positions and angles, and thus, different light display changes can be presented through the light source module 12 to enhance the visual reminding effect, so that the warning effect is greatly and effectively increased; therefore, different display settings and modulation are performed on the light source module 12 through the modulation control module 13, so that the light source module 12 can generate different light display change modes at any set point at different angles, which is different from the known problems that the adjustment control of the light display change of the LED cannot be accurately modulated at the same time, and the ideal warning effect is effectively achieved.

Referring to fig. 4, a display device 1 for light display change according to a second preferred embodiment of the present invention is applied to an indicating device having various angular directions of movement or a barrier 2 having an up-down movement, etc., and the present embodiment is described by taking the barrier 2 applied to the up-down movement as an example, and the barrier 2 has an up-down swing arm 20 on which the display device 1 is mounted and a power source 21 (shown in a diagram) for driving the display device 1 to swing up and down; the display device 1 for changing the light display of the present embodiment still includes a main body 11, a light source module 12 disposed in the main body 11, and a modulation control module 13 (schematically shown in the figure) disposed in the main body 11 and capable of controlling and modulating the operation of the light source module 12; wherein, the embodiment is particularly characterized in that the inertia measurement assembly 131 has an accelerometer 1311 and a gyroscope 1312, and the gyroscope 1312 is capable of further correcting errors of the values of the body elevation angle and the moving speed calculated by the accelerometer 1311, that is, when one side of the body 11 is used as a reference fixed point to perform the up and down movement of the body elevation angle, the accelerometer 1311 is capable of performing the measurement at the moment of the movement of the body 11 and performing the calculation according to the measured values of the distance and the angle, and the gyroscope 1312 is capable of further correcting errors of the linear acceleration values of the angular speed calculated by the accelerometer 1311 to improve the accuracy of the angle of the body 11 elevation movement and is connected to the driving processor 132; in addition, the light source module 12 is described by using a light source mode in which three primary color lamps, such as a red LED, a green LED, and a yellow LED, are combined in a single body, so that the setting mode can be set according to different use requirements, and the number ratio of the red, green, and yellow LEDs driven by the driving processor 132 shows different light display changes along with the movement lifting angle, that is, for example: it can be set to set 0 degree as red LED, 45 degree as yellow LED and 90 degree as green LED in the lifting angle θ, so that the red, yellow and green LEDs can stably show single, whole, partial and mixed continuous illumination effect at the set point or single, whole, partial and mixed flash illumination effect during the different movement and lifting angles of the light source module 12 along with the body 11, therefore the setting mode can be set according to the different requirements, the quantity ratio of the red, green and yellow LEDs driven by the driving processor 132 changes with the movement lifting angle, and the expression formula is determined as follows:

LED_G＝θ×1.11

or is shown as

LED_R＝100－θ×1.11

Wherein the LED_GIs the proportion (%) of the number of green LEDs driven at a lifting angle theta; LED (light emitting diode)_RIs a proportion (%) of the number of red LEDs driven at the rise and fall angle θ.

If the body 11 is moved horizontally, i.e. the lifting angle θ is 0 °, the light source module 12 is driven by the driving processor 132 to be red LEDs, and the color tone of the light emitted outwards through the corresponding light-transmitting area 112 is red, the formula is determined as follows:

LED_G0 × 1.11, 0% green LED

LED_R100-0 × 1.11, 100% red LED

If the body 11 is moved to be raised to a half way, that is, the raising angle θ is 45 degrees, the light source module 12 is driven by the driving processor 132 to be a half red LED and a half green LED, and the colors of the light emitted outwards through the corresponding light-transmitting area 112 are yellow, the formula is determined as follows:

LED_G45 × 1.11, green LED ≈ 50%

LED_R100-45 × 1.11, red LED ≈ 50%

If the body 11 is moved vertically, i.e. the lifting angle θ is 90 degrees, the light source module 12 is driven by the driving processor 132 to be green LEDs, and the color tone of the light emitted outwards through the corresponding light-transmitting area 112 is green, the formula is determined as follows:

LED_G90 × 1.11, green LED ≈ 100%

LED_R100-90 × 1.11, red LED ≈ 0%

As can be seen from the foregoing, the accelerometer 1311 can measure and calculate the elevation angle, and the gyroscope 1312 corrects the error of the linear acceleration value through appropriate matching, so that the driving processor 132 can effectively and reliably modulate and control the light source module 12 to accurately present the required light emitting mode and color tone.

Referring to fig. 4 to 5, firstly, a predetermined setting may be performed according to what display condition is to be generated by the light source module 12, for example: setting the body 11 as red LED when the body is horizontally displayed at 0 degree, setting yellow LED when the half height of the body 11 is raised reaches 45 degrees, and finally setting green LED when the body 11 is vertically displayed at 90 degrees, so as to store various driving setting values to be performed by the light source module 12 in the driving processor 132, and certainly, the enhancement and the weakening of the light emitting display mode or the flicker can be synchronously set in the driving processor (which will not be described in detail below); therefore, when the swing arm 20 is in a horizontal state, the light source module 12 can be displayed with red LED status through the body 11 with high light transmittance, and when the swing arm 20 is controlled by the outside and is moved upward from the horizontal state, the modulation control module 13 will deploy the start mode when the swing arm 20 is initially moved, and after receiving a proper command, the body 11 is immediately moved upward under the action of the swing arm 20, at this time, the accelerometer 1311 will measure the angular velocity of the body 11 in a synchronous manner, and through the design of the gyroscope 1312 with an error characteristic of correcting the linear acceleration, the measured value is connected to the driving processor 132 for analysis, processing and comparison, so that after the light source module 12 receives a real driving command from the driving processor 132, when the swing arm 20 moves to rise to a half 45 degree angle, the light source module 12 will immediately display a complete yellow light display through the body 11, i.e. as shown in fig. 6, and of course, with the difference in rising angle, the light source module 12 will also display a complete green light display through the transparent regions 112 under the continuous measurement modulation control of the modulation control module 13, until the fence rises and stops at the vertical 90 degree angle, i.e. as shown in fig. 7, therefore, the light source module 12 will immediately display a complete green light display through the transparent regions 112, i.e. through the modulation control module 13, so that the light source module 12 can generate different light brightness and color variation modes for any set points of different angles, thereby controlling the swing arm 20 to generate strong light display or alarm with different colors during the up-down rising and rising angles of the swing arm 20 The reminding function is different from the known problem that the control of the color tone alternation of the LED can not be accurately modulated at the same time, so that the convenience of accurately modulating, controlling the light display change and implementing and applying can be effectively achieved.

Referring to fig. 8, the display device 1 for light display change according to the third preferred embodiment of the present invention is illustrated in the fence 2 that moves up and down on the intersecting road, that is, the display device 1 for light display change according to the present embodiment still includes a main body 11, a light source module 12 disposed in the main body 11, and a modulation control module 13 (schematically illustrated in the figure) disposed in the main body 11 and capable of controlling and modulating the light source module 12, and the inertial measurement component 131 includes an accelerometer 1311 and a gyroscope 1312; wherein, the lifting distance of the main body 11 rising to descending along with the fence 2 can be divided into several moving distance settings (hereinafter, it is divided into three moving sections), that is, the rising location point starting to operate is set as the first section capable of going through, the light source module 12 is set to emit light to display as the outward light display of the all-green LED, when the rising location point descends to the second section capable of warning, the light is set to display as the outward light display of the all-yellow LED (as shown in fig. 9), when the rising location point descends to the third section position capable of blocking the passing, the light is set to display as the outward light display of the all-red LED (as shown in fig. 10), and as can be seen from the foregoing, when the fence 2 moves up and down, the distance of the lifting moving speed can be measured and calculated by the accelerometer 1311, and the error can be further corrected by the coordination of the gyroscope 1312 by the values of the lifting angle and moving speed of the main body 11 calculated by the accelerometer 1311, therefore, the driving processor 132 can effectively and really modulate and control the light source module 12 to accurately present the required light emitting display outwards through the body 11, which is different from the known problem that the control of the color tone alternation of the accurate modulation LED cannot be simultaneously achieved, and the like, so that the fence 2 provided with the invention can generate strong light emitting display with different color tones in the process of the up-and-down movement of the action to perform the blocking function of warning and reminding, thereby effectively achieving the convenience of accurately modulating and controlling the light display change and implementing application.

Referring to fig. 11, in a fourth preferred embodiment of the present invention, the display device 1 can be applied to a fence 2 having an up-down swing arm, and the fence 2 has an up-down swing arm 20, a stopper 22 disposed on one side of the swing arm 20 and adapted for the display device 1 to be disposed thereon, and a power source 21 (schematically illustrated in the drawing) for driving the swing arm 20 to swing up and down and change the light display of the display device 1, and the display device 1 still includes a main body 11, a light source module 12 disposed in the main body 11, and a modulation control module 13 (schematically illustrated in the drawing) disposed in the main body 11 and capable of controlling the modulation of the light source module 12, and the inertia measuring assembly 131 has an accelerometer 1311 and a gyroscope 1312, and the display modes of the light source module 12 can form different arrangement display modes according to the intended use, that is, the arrangement is the exit, entrance, or no-pass type, etc., and the display forms with various reminding functions are illustrated in the figures only by way of example that the light source module 12 is arranged as the entrance display form, so that the light source module 12 can be actuated along with the movement of the swing arm 20 and can present different light display changes under the control of the modulation control module 13; of course, the stopper 22 can be made of canvas, iron or acrylic.

Fig. 11 to 13 show how the light source module 12 is going to move along with the swing arm 20 before use, and the modulation control module 13 is linked to each other, which can be preset, so that when the swing arm 20 is in a horizontal state, the light source module 12 on the stopper 22 shows that the LEDs are all in an outward display light emitting state, and when the swing arm 20 is controlled from the outside to be in a rising state from the horizontal state, and the stopper 22 moves to a half 45 degrees along with the rise of the swing arm 20, the modulation control module 13 will analyze, process and compare the data obtained by the movement measurement, so that the light source module 12 can show only part of the light emitting states of the LEDs outward after receiving a real driving instruction from the modulation control module 13, as shown in fig. 12, and then when the swing arm 20 is stopped at a vertical 90 degrees position, the light source module 12 will immediately receive the instruction of the modulation control module 13 to stop the LED from displaying the light emitting state, that is, as shown in fig. 13, so that different display settings and modulations are performed on the light source module 12 through the modulation control module 13, so that when the stopper 22 moves along with the fence 2, the display device 1 can be controlled to generate different light brightness and color tone changing modes at any set point at different angles, so as to generate strong light emitting display or warning and reminding functions with different color tones during the moving process, thereby effectively achieving the convenience of precisely modulating, controlling the light display change and implementing and applying.

In conclusion, the display device for light display change of the present invention utilizes the mutual cooperation of the inertia measurement component of the modulation control module and the driving processor, so that the body can perform multi-axial measurement aiming at the linear acceleration value of the movement in different lifting and moving angles, and accurately calculate the values of the lifting angle, the moving speed, etc. so as to enable the outward light display change of the light source module to be effectively modulated and controlled, and then the gyroscope in the inertia measurement component can cooperate with the calculation of the accelerometer and the error correction of the linear angle value, and adjust and set aiming at the measured angle value, so that the light source module can be really linked by the driving processor, thereby facilitating the light source module to generate accurate light brightness and color change after being modulated and controlled, and further achieving the aim of generating the light display function of bright and dark at any set point, meanwhile, the fence which is arranged in an open parking place or used on a level crossing and the like is used, so that better reminding and warning effects are achieved.
