In many sporting events, for example, ball events, particularly ball games, such as basketball, in which timing is required, particularly basketball 24 seconds devices, to increase the rhythm of the game, such as during a foul, pause, serve, penalty, etc. The offender starts timing from the ball serving to the hands of the player on the own side, the basketball is required to finish the actions of 'beating the board' or 'bumping the basket' within 24 seconds, after the actions are finished, the timer returns to 0 again to start timing for 24 seconds, and the situation that the actions cannot be finished within 24 seconds is regarded as 24 seconds is considered as a violation. If the remaining time displayed on the 24 second device is more than 14 seconds when the race is stopped, the 24 second device is not reset but the race should continue from the position where it was stopped. If the remaining time displayed on the 24 second device is less than 13 seconds when the race is stopped, the 24 second device should be reset to the position where 14 seconds remain to continue the race.

Example 1:

The embodiment provides a transparent countdown device, which is shown in fig. 1-4 of the specification, and specifically comprises a frame shell 1 and a light-transmitting body 4 fixedly installed on the frame shell 1 and used for displaying at least one group of countdown modules, wherein an installation cavity 11 used for accommodating and installing a control circuit board is arranged in the frame shell 1, and the control circuit board is electrically connected with any group of countdown modules arranged in the light-transmitting body 4. In order to realize multi-view and multi-angle display, the problem of a large number of existing competition field display screens is solved, and in the embodiment, the front surface and the back surface of the light-transmitting body 4 are arranged in a central symmetry manner. The light-transmitting body 4 adopts positive/negative two-sided synchronous display, can simultaneously display countdown to the personnel in opposite directions, realizes that a countdown reaches the technical effect of current two display screen countdown, and the energy consumption is lower, and space volume occupies littleer, and the display angle is more, and visual effect is more penetrating.

The functions of the frame housing 1 include: for connection with brackets or fasteners to enable installation in different environments, such as on a wall, by vertical placement of brackets on a playing field, etc.; meanwhile, a stable structural protection is provided for the light-transmitting body 4, and the light-transmitting body 4 is supported and fixed; furthermore, the physical accommodation/installation space is provided for the control circuit board which is used for providing the electric signal for the countdown module for displaying the countdown on the light-transmitting body. The frame housing 1 may be variously configured, for example, rectangular, circular, polygonal or any other structure capable of effectively accommodating or fixing the light-transmitting body 4. Because the countdown module installed in the light-transmitting body 4 only comprises a countdown display area, and the non-display area is of a transparent structure, the number of LED lamp beads required to be driven is greatly reduced compared with the number of LED lamp beads required to be driven in the prior array type LED screen project, and the energy consumption of the LED lamp beads of the screen can be reduced by 80 percent by about 20 percent. The screen length is 1 meter, the width is 0.7 meter, the led lamp beads are arranged in an array with the 5mm interval, 200 led lamp beads are arranged in each row, 140 led lamp beads are arranged in each column, and 28000 led lamp beads need to be controlled in the whole screen; however, according to the embodiment, according to a group of small four-digit countdown and a group of large two-digit countdown, the arrangement is needed to be enough to cover 5000-5500 led lamp beads in series, which accounts for about 20% of the existing array type screen led lamp beads, so that the number of led lamp beads to be controlled is greatly reduced, and the energy consumption and the failure rate are correspondingly greatly reduced.

Adopt the printing opacity body 4 as the luminous element of display, except the countdown of display, other regions are transparent or fretwork setting, can not cause the shielding to realizing, current array display screen, and led lamp pearl area that does not light can cause the vision to shelter from, and this embodiment has higher impression in current screen.

It should be emphasized that the timing of the present utility model should be understood to be timing, simply because reverse timing is adopted, that is, reverse timing is more striking for practical event applications, in most cases, however, for the technology itself, forward timing and reverse timing are not substantially different, and both forward timing and reverse timing are actually timing functions, are not substantially different, and only the timing display order is reverse to each other, so that it cannot be understood to be countdown in a narrow sense only.

The edges of the 5 layers of glass are bonded by adopting a bonding mode between the layers of glass to form an integrated structure, for example, glass cement is adopted, so that the 5 layers of glass cannot be broken due to stress concentration caused by extrusion, an integrated structure can be effectively formed, and good transparent vision can be maintained. It is worth noting that the first toughened glass 41 and the second toughened glass 45 which are positioned on the outer layers of the two sides mainly protect led lamp beads of the countdown module and a circuit between the led lamp beads, so that the problem of damage caused by unexpected external force collision in the processes of use, transportation and the like is avoided. The thicknesses of the first toughened glass 41 and the second toughened glass 45 which are positioned on the outer side are larger and are generally set to be 3-7 mm, so that the LED lamp beads have extremely high external force resistance, and meanwhile, a clearance cavity 46 for accommodating and mounting the LED lamp beads is arranged between the first toughened glass 41 and the first conductive glass 42 and between the second toughened glass 45 and the second conductive glass 44, so that the LED lamp beads are prevented from being stressed. The adjacent two led lamp beads are electrically connected in series through conductive adhesive on conductive glass, the led lamp beads preferably adopt six-pin led lamp beads, and referring to fig. 7, any led lamp bead comprises a pair of anode pins, a pair of signal pins and a pair of standby signal pins, namely the signal pin of a certain led lamp bead breaks down, and the standby signal pins can normally provide signals, so that the fault rate and maintenance frequency are reduced.
