Description

201006426 IX. Description of the Invention: [Technical Field] The present invention relates to a coaster, in particular to a light-emitting diode cup that can sense the pressure and drive the light-emitting diode to change the color light according to different pressures. Prior Art In the hot summer, people often like to drink cold drinks. When the ice drink is placed on the tabletop, the water will be condensed on the outer surface of the cup, so people will use the coaster to place the cup and the table. In addition, it can avoid the trouble of desktop water collapse and prevent the cup from slipping. In order to make the coaster 旎 more added value, Taiwan’s new patent M240938 “(4) structure with entertainment and lighting effects” is an example in which a circuit device and a light-emitting element are arranged inside the cup, so that the cup has a light-emitting function. It even has the visual effect of flashing lights, which adds to the artistic beauty of the cup. • However, these illuminating functions are mostly cyclical changes of the system, or even a single color that is constant, and the illuminating function of the coaster combined with the illuminating function is dull and boring. [Description of the Invention] As can be seen from the above description, although the acquaintance of the slaves is a function of the illuminating function, it is mostly a system change, which is dull and boring. The coaster has a clock. The main purpose of the present invention is to sense that the cup placed on the coaster provides a cup weight of the light-emitting diode and displays different colors of 201006426, so that the light-emitting display of the coaster reaches a perceived environment. The effect of stress. The main technical means for achieving the above purpose is that the light-emitting diode cup includes: a light-transmitting pad body; a pressure sensor is disposed in the light-transmitting pad body to sense the light transmission a surface pressure of the pad body and outputting different pressure value signals according to different pressures; a control circuit board is disposed in the light transmissive pad body and is provided with a plurality of light emitting bodies, and the control circuit board is connected to the pressure sensor Receiving the pressure value signal transmitted by the LED, and controlling the illumination of the LED according to different pressure values. When a cup containing a beverage is placed on the light-emitting diode cup, the control circuit board uses a pressure sensor to sense the weight change of the surface of the coaster to control the lighting of the light-emitting diode according to the weight change. . [Embodiment] Referring to the first embodiment, a preferred embodiment of the present invention includes a light-transmitting pad body (1 〇), a pressure sensor (2 〇), and a control circuit board (30). ). The light-transmitting pad body (1 ) ) is a square shape. In this embodiment, the light-transmitting pad body (10 ) is a square shape. a transparent plastic pad body, and at least one light guide plate (11) is vertically disposed at a peripheral edge thereof, and the light guide plate (11) can be further engraved, laser processed, etc. to further form a texture (1 2 ), when the color light passes through the texture (12) Better visual effects due to refraction. 201006426 The pressure sensor (20) is disposed in the light-transmitting pad body, and can sense the surface pressure of the light-transmitting body (1 〇) and output different pressure value signals according to different pressures. In this embodiment, the pressure sensor (20) is a piezoresistive type flexible pressure sensor. The control circuit board (3 〇) is located in the light-transmitting pad body (i 〇) and is provided with a plurality of light-emitting diodes (3 i ). In this embodiment, the light-emitting diodes (3 1 ) are respectively It is disposed on the four peripheral e edges of the control circuit board (3 〇) and corresponds to the position of each light guide plate (11), and may include three colors of red, blue and green. As shown in the second figure, each of the light emitting diodes (31) may further correspond to The texture of the light guide plate (1 1) '1 2 refracts the generated color light through the grain (1 2) to produce a better visual effect; the control circuit board (3 〇) is connected to the 5 hai pressure sensor (2 〇 And including a memory in which the lighting driver is stored. The control circuit board (3 〇) controls the light-emitting diode (3 1 ) to emit light by executing the lighting driver and according to the received pressure value signal. When a cup is placed on the light-transmitting pad body (1 〇), the pressure sensor _ (2 0 ) senses the pressure value and transmits it to the control circuit board (3 〇), according to which the light is turned on. control. The aforementioned texture (12) can be designed in a variety of shapes to achieve different visual effects. As shown in the third figure, the texture shape (12) can be designed to exhibit a wide and narrow column shape. Referring to the fourth figure, the foregoing lighting driver includes the following steps in the embodiment: obtaining a pressure value (100), obtaining a pressure value through a pressure sensor (20), the pressure sensor ( 2 〇) The pressure value of 201006426 can be transmitted every other time interval; the pressure value (101) is recorded, and the pressure value record obtained is stored in the memory of the control circuit board (30); (102), it is judged whether the pressure value obtained this time is the same as the pressure value obtained in the next time. If the same, the pressure value measured according to the current stage is controlled to light, otherwise the next step is performed; Measure the relationship between the pressure value and the previous two pressure values Q (103), and determine whether the pressure values measured at the current stage are greater than or less than the pressure values of the previous two measurements; Lamp (1〇4), if it is judged that the pressure values measured at the current stage are both greater than or less than the pressure values of the previous two measurements, the pressure value measured according to the current stage is controlled to light; Way to control the free light (1 0 5), if judged Stage are measured pressure value is not greater or less than all of the two previous measured pressure value is determined by weight of the cup is in an unstable state, so that the previous stable lighting by the lighting control manner φ. If the weight of the cup is unstable, it may be caused by the shaking of the liquid contained in the cup body. Therefore, the sensed weight will be suddenly large or small. For example, by comparing the measured values of three times before and after, it is judged whether or not If it is in a shaking state, if it is in a state of unstable shaking, the state of the last stable lighting is maintained, and after the cup returns to a stable weight, it changes to the corresponding color according to the existing weight. The invention mainly uses the control circuit board and the pressure sensor to be disposed in the whole of the light transmission, thereby sensing the weight change of the cup surface, thereby controlling the lighting of the light emitting diode according to the weight change of the 201006426, for example, different weight sections. The color is displayed in different colors, and the coaster itself can achieve the effects of light scattering and refraction by engraving, etc., so that the color light display of the light-emitting diode is more dazzling.
