Abstract
The utility model relates to an LED structure for a ceiling fan and is used for imaging on the blade of the ceiling fan and can be used for displaying characters or graphs. The LED structure is structurally characterized by comprising a power supply. The power supply is respectively connected with an LED matrix for displaying, a position sensor and a central processing unit; the LED matrix for displaying is respectively connected with the central processing unit and the power supply; the position sensor is respectively connected with the central processing unit and the power supply; and the central processing unit is respectively connected with the power supply, the LED matrix for displaying and the position sensor. Compared with the prior art, the lowest imaging revolution speed of the LED structure for the ceiling fan is 30 RPM (Revolutions Per Minute); the LED structure can be used for displaying the characters and the graphs, and can display the graphs of LED arrays, wherein the LED arrays comprises more than two strings of serial LEDs, the LED structure can realize the complete imaging through the LED arrays in a low-speed environment, and thereby, the condition of incomplete imaging caused by insufficient revolution speed is remedied, and the application range of an LED fan blade display on the blade of the ceiling fan is greatly broadened, so that the effect that the blade of the ceiling fan is completely imaged at the low revolution speed can be achieved.
Description
Technical field
The utility model relates to the LED structure on a kind of blade for ceiling fan, specifically relates to a kind of LED of utilization structure and is implemented in the blade for ceiling fan structure that forms complete imaging under the slow-speed of revolution.
Background technology
The product that many electric fan display text patterns are arranged at present on the market, it utilizes the persistence of vision principle to come display text and pattern, suitable interesting and very with practical value of its function, but there is a very big shortcoming in this system, be exactly that its display effect just can't present, because on the product of ceiling fan when rotation speed of the fan is not enough, the flabellum range of speeds is that 30～500RPM belongs to the slow-speed of revolution, does not have this Related product.
Summary of the invention
The purpose of this utility model provides a kind of ceiling fan flabellum display that can finish complete imaging under the slow-speed of revolution, and this ceiling fan can be realized complete imaging by the LED matrix under the environment of slow running.
The utility model solves the scheme that its technical matters takes:
A kind of LED structure that is used on the blade for ceiling fan is characterized in that comprising power supply, CPU (central processing unit), LED matrix, position sensor; Described power supply connects respectively and shows with LED matrix, position sensor, CPU (central processing unit); Described demonstration connects CPU (central processing unit) and power supply respectively with the LED matrix; Described position sensor connects CPU (central processing unit) and power supply respectively; Described central authorities handle single a kind of power supply, demonstration LED matrix, position sensor of connecting respectively.
A kind of LED structure that is used on the ceiling fan of the utility model design, structure is installed on the flabellum of ceiling fan motor, simple in structure, minimum imaging rotating speed is 30RPM, can demonstrate literal and figure, can display graphics be LED, LED is serial, and be the above led array of 2 strings, can under low speed environments, realize complete imaging by the LED matrix, thereby remedy owing to the not enough incomplete situation of imaging that causes of rotating speed, improved the scope that LED flabellum display uses greatly on ceiling fan, thereby made ceiling fan can be issued to the effect of complete imaging in slow-revving situation.
Description of drawings
For clearer explanation design feature of the present utility model, the utility model is further detailed below in conjunction with drawings and Examples.
Fig. 1 is a kind of circuit block diagram of ceiling fan flabellum display.
Fig. 2 is a kind of structural drawing of ceiling fan.
In the accompanying drawing, the list of parts of each label representative is as follows:
1: power supply; 2: CPU (central processing unit); The 3:LED matrix; 4: position sensor; The 5:N utmost point; The 6:S utmost point; 7: the Hall sensor; The 8:LED display; 9: flabellum.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is described further, but not as to qualification of the present utility model.
Be embodiment below:
A kind of be used on the ceiling fan LED structural circuit calcspar as shown in Figure 1, comprise power supply 1, power supply 1 connects respectively and shows with LED matrix 3, position sensor 4, CPU (central processing unit) 2; Described CPU (central processing unit) 2 connects LED matrix 3 and position sensor 4 respectively.
A kind of LED structure that is used on the ceiling fan, as shown in Figure 2, its method of operation is: at the ceiling fan body apparatus one N utmost point 5 one S utmost points 6 magnet, device one Hall element 7 on LED flabellum display 8, when fan rotates, Hall element 7 can sense the magnetic pole on the ceiling fan body and feed back a square-wave signal to central processing unit, the frequency of the present square-wave signal of central processing unit analysis can be calculated present rotating speed, with 360 parts of branches such as square-wave signal, can be obtained the angle of present running this moment by square-wave signal.When rotating speed is fast, light-emitting diode display 8 only need use 1～3 group of LED matrix to show, just enough cause persistence of vision can make human eyes see literal or image, when rotating speed is slack-off, use 3～8 groups of LED matrixes to do demonstration, the problem that is difficult for imaging that causes excessively slowly with compensating rotational speed.
The above only is preferred embodiment of the present utility model, not in order to restriction the utility model, and all common variations of in the technical solution of the utility model scope, carrying out and be equal to replacement and all should be included in the protection domain of the present utility model.
Claims (4)
1. a LED structure that is used on the blade for ceiling fan is characterized in that comprising power supply, CPU (central processing unit), LED matrix, position sensor; Described power supply connects respectively and shows with LED matrix, position sensor, CPU (central processing unit); Described CPU (central processing unit) connects respectively and shows with LED matrix, position sensor.
