specific Embodiment

[0033] 1) The lifting system consists of horizontal guide rails, vertical guide rails, load beams and 20 motion units, and each unit includes 2 lifting trolleys, trusses and other auxiliary equipment.

[0034] 2) The lifting trolley is composed of a motor, a reducer and gears, etc. The power of the motor is 18.5 kw, and the total power of the system is 18.5×2×20=740 kw.

[0035] 3) Each motion unit weighs about 19 tons (14 tons for the truss (including LED), 5 tons for the lifting trolley), and the total weight is 19×20=380 tons.

[0036] 4) The lifting motion and synchronization accuracy of the system are controlled within 10 mm, which can meet the safety requirements of the system and the display requirements of LEDs.

[0037] 5) It takes about 20 minutes for the system to be fully lifted (or lowered) to its place.

[0038] The invention controls the opening and closing of the LED display screen through the light intensity information, and realizes automatic control. During t...

Abstract

The invention discloses a lifting LED display screen controlled by light. The lifting LED display screen comprises an LED display screen control system, an LED screen body, an LED screen body lifting system, a lifting control system and a power supply system. The LED screen body comprises a plurality of display units, and each display unit comprises a plurality of LED lamp bars. The LED lifting system comprises a horizontal guide rail, a vertical guide rail, two lifting carts, one truss and auxiliary equipment, wherein the horizontal guide rail is used for drafting and guiding the lifting carts in the horizontal direction, the vertical guide rail is used for lifting the truss, the auxiliary equipment is used for fixing the LED lamp bars, and the horizontal guide rail is connected with the vertical guide rail through an arc-shaped guide rail. A light sensor used for detecting the light intensity of the ambient environment is arranged at the top end of the vertical guide rail. The LED display screen is controlled to be switched on and switched off through light intensity information, automatic control is achieved, and the value of the LED display screen is effectively utilized.

Description

technical field [0001] The invention belongs to the application field of LED electronic products, and in particular relates to a light-controlled liftable LED display screen. Background technique [0002] While my country's LED display industry is developing on a large scale, product technologies are being introduced to new ones and have maintained a relatively advanced level. In the early 1990s, it possessed mature 16-level grayscale 256-color video control technology and wireless remote control and other national advanced level technologies. There are domestically advanced technologies and products that have reached the international level in terms of control technology and other aspects; LED display control dedicated large-scale integrated circuits have also been developed, produced and applied by domestic enterprises. However, compared with foreign advanced technologies, there are still some key technologies that need to be improved: [0003] One is the problem of insu...
