The lamp efficiency control method of the present invention will be described in detail with reference to fig. 1 to 3.
In this embodiment, the light effect control method is applied to a sound provided with an LED lamp for light effect exhibition, including:
s101: creating a light effect thread and a music following thread, determining and executing a light effect mode according to the light effect operation instruction after receiving the light effect operation instruction, and executing S102.
In this embodiment, the step of creating the light effect thread specifically includes: the method comprises the steps of initializing and creating a linked list, initializing structural bodies in the linked list and adding structural body variables, wherein different linked lists correspond to different light effect modes.
The light effect thread uses the light service to manage the light, namely if the sound equipment needs to display the light effect, the light effect thread is uniformly handed to the light to be executed by proxy instead of directly operating the light. The reason for this is the following:
1. and the developer can write complex lighting effects conveniently. Lightd provides an abstract library of effects lighting effects that developers can easily combine and execute in sequence.
2. And (5) managing resources. Direct operation of the LED is simplest if there is only one lamp effect. If you have 2 light effects, an extra bit of code is needed to ensure the execution sequence of the light effects, and if more than 3 light effects exist, the resources occupied by the code need to be confirmed.
3. Threads are asynchronous and at any time, a problem arises if there are 2 programs to operate the lights at the same time. If light effects are animations that transition within a certain time, they must be manually interrupted when the second light effect is executed. Transitional animations are used, meaning that timers are used, and to manually interrupt them, handles of the timers must be saved, you can find that all the handles of the timers and the codes for canceling the timers are in the codes, and the real light effect codes only account for a small part. All of the above are managed by effects using the effects library provided by lightd. The developer does not worry about having 2 effects executing simultaneously, nor does it manage timers.
4. And (5) modularization. And the lightd saves each light effect file as a separate thread file, so that the code coupling degree is lower, the maintainability and the readability are higher, the problem of variable renaming is not needed to be worried, and each file is a separate scope.
5. A recovery mechanism. The light can restore the lamp effect at the proper time. If the forbidden wheat light effect is played currently and a volume light effect is suddenly generated, the forbidden wheat needs to be recovered after the volume light effect is executed. The light will automatically resume.
6. A priority mechanism. The light can ensure that the light with high priority is executed preferentially. The light effect with high priority is always executed preferentially, and the light effect developer does not need to worry about being interrupted and has a recovery mechanism even if being interrupted. The system light effect priority is configured by a configuration file and is dynamically adjustable for a user.
Specifically, the linked list used in the light effect thread includes one or more of a one-way linked list, a two-way linked list and an annular linked list, and a developer can select the corresponding linked list according to the content of the light effect mode and the user requirement. And the structure in the linked list is a light structure variable. The structure variables include (light _ id, light _ address, data _ r, data _ g, data _ b, next, prior), which respectively correspond to the number of lamps, addresses, RGB member values, and the order in which the lamps are converted by pointers. When the light effect thread is operated, a function is exported through the file of the light effect thread, the function receives parameters, and when the function is executed, light calls the function to realize corresponding light effect mode control.
In one embodiment, the light effect thread implements light effect control according to light effect priority. Wherein the light effect priority control comprises: 1. when the high priority light comes, the low priority light is not displayed. If the light with low priority needs to be recovered, the light is put into a corresponding recovery queue. 2. When the light A at the same level comes, the light B at the same level can interrupt the light A.3. When the low-priority light comes, the high-priority light interrupts the low-priority light. 4. And after the current light is executed, recovering the first light from the recovery queue from high to low according to the priority. 5. And the light effect thread executes the light effect operation according to a built-in timer. 6. The system light effect priority is always higher than the user light effect priority regardless of the size.

The flashing light does not flash when no music exists, and flashes according to the rhythm of the music when music exists.
And in the third mode, when no music exists, the three colors of red, orange and purple move and change, and when music exists, the three colors of red, orange and purple are lightened and extinguished from top to bottom in the middle according to the music rhythm and change color by color according to the seven colors. The lamp ring of the upper horse race lamp in the horse race lamp starts to emit light from the bottom when no music exists, the bottom is extinguished when the light-emitting position reaches the middle part, the light is on and off and the light is emitted to the top continuously, the same operation is circulated from the bottom after the light is extinguished, meanwhile, when music exists according to seven-color change (one color is used in each circulation), the bottom is on, the number of the light is fluctuated up and down according to the leap rhythm, and meanwhile, the seven colors are changed. The lantern ring of the lower running lantern starts to be lightened from the top when no music is available, and the top is extinguished when the lightened position reaches the middle part, and the lightening and extinguishing are continuously carried out until the lantern at the bottom is extinguished. The above cycle is repeated from top to bottom while cycling through the colors (one color per cycle). When music is available, the top of the lower horse race lamp emits light, the number of the light-emitting lamps fluctuates up and down according to the rhythm of the music, and the light-emitting lamps are changed in colorful colors. When the lamp belt has no music, the lamp belt emits light upwards from the bottom, when the light-emitting position reaches the middle part, the bottom is turned off, and the continuous on-off operation extends to the turning off of the lamp at the top. This operation is repeated in cycles and displayed in seven colors (one color for each cycle) with the color of the light strip being consistent with the ticker. When music is available, the middle part is bright, the fluctuation is up and down according to the music rhythm, and simultaneously, the color changes of the horse race lamp and the lamp strip are synchronous according to the seven-color change. The flashing light does not flash when no music exists, and flashes according to the music rhythm when music exists.
And in the fourth mode, when no music exists, the flame effect is changed according to the free rule of the flame effect, and when music exists, the change height of the flame is changed according to the rhythm of the music. The horse race lamp is when no music, and from the lower left side, both sides are luminous upwards, and after luminous position extended to the middle part, the lower left corner began to extinguish, and the operation of bright going out lasts to the top right portion and extinguishes. After all lamps are extinguished. From the lower right corner, both sides are luminous upwards, and after luminous position extended to the middle part, the lower right corner began to extinguish, and the operation of bright going out lasts to the top left and extinguishes. The above operations are cycled through, keeping each cycle using a different color (the color is seven). And when music exists, the lamp effect is circularly executed according to the change rule of the music when no music exists. The flashing light does not flash when no music exists, and flashes according to the rhythm of the music when music exists. When the lamp strip is silent, the left lower side of the lamp strip starts to light, the lamp strip emits light upwards from two sides, when the light-emitting position reaches the middle part, the bottom of the left side starts to extinguish, the lighting and extinguishing operations continue to extinguish the right top of the lamp strip, after all the lamps are extinguished, the lamp strips on the two sides start to emit light upwards from the lower right corner, after the light-emitting position reaches the middle part, the lamp strip on the lower right corner is extinguished, the lighting and extinguishing operations continue to extinguish the lamp strip on the top left, all the lamp strips are extinguished, and therefore, the cycle is repeated, each cycle of the lamp strip is controlled to emit light with a color, and the color is consistent with the color of the horse race lamp. When music is available, the lamp strip emits light according to music, the light emitting lamp flickers according to music rhythm, and the color of the horse race lamp and the color of the lamp strip are kept synchronous. The flashing light does not flash when no music is available, and flashes according to the music rhythm when music is available.
And in the fifth mode, when no music exists, the music is gradually changed in a circulating mode according to a set mode sequence, and when music exists, the music is changed in a circulating mode and flickers according to the rhythm of the music. When no music is available, two fifths of the horse race lamp shines in colorful colors and turns clockwise to shine. When music exists, the display mode is the same as that of music-free music, and the rotation speed is changed according to the rhythm of the music. When the lower horse race lamp does not have music, two fifths of the lamps emit light in colorful colors and rotate counterclockwise to emit light. When music exists, the light emitting mode is the same as that of music, and the rotation speed is changed according to the rhythm of the music. The lamp strip is displayed in a colorful mode when no music exists, changes circularly from bottom to top (each cycle lasts for 0-5 s), and is lightened in a colorful mode when music exists, and changes up and down according to music rhythm when each cycle lasts for 0-5 s. The flashing light does not flash when no music exists, and flashes according to the music rhythm when music exists.
And in the sixth mode, when no music exists, the music is gradually changed in a circulating mode according to a set mode, and when music exists, the music is changed in a circulating mode according to the set mode and flickers according to the rhythm of the music. The horse race lamp is when no music, all wait until seven various colour gradual changes, when having the music, glimmer according to the music rhythm. The light emitted by all the lamps of the lamp strip is in the same color, and is synchronous with the horse race lamp according to the frequency of the gradual change of the colors of the seven colors. The change rule is that the lamp strip changes left and right continuously, the color change direction of the lamp on the lamp strip is clockwise first, and the change interval is 1s in anticlockwise. When music is available, the music flickers according to the music rhythm. When music flickers, the marquee and the lamp strip do not flick at the same time, and the time for the two-time flashing of the marquee is longer than the time for the two-time flashing of the lamp strip and longer than the time for the one-time flashing of the marquee. The flashing light does not flash when no music exists, and flashes according to the music rhythm when music exists.
