Multi-mode control device based on television LED lamp

Abstract

The invention provides a multi-mode control device based on a television LED lamp. The multi-mode control device connected with an LED lamp comprises an input module, a receiving module, a storage module, and a drive module. The receiving module connected with the input module is used for receiving mode selection information and state conversion information and outputting the received information. The storage module is used for storing a plurality of control strategies corresponding to a plurality of modes. The drive module connected with the receiving module and the storage module is used for receiving the mode selection information and state conversion information, invoking a corresponding control strategy from the storage module according to the mode selection information, and controlling turning on / off and the luminance of the LED lamp by adjusting a duty ratio based on the control strategy and the state conversion information. The multi-mode control device has the following beneficial effects: different control strategies are employed under various control modes; the LED control need of the user in different scenes is met; on the basis of multi-mode control, the turning on / off and the luminance of the LED lamp are controlled by adjusting the duty ratio; and the LED luminance is adjusted in different scenes, so that the standby power consumption is reduced.

Description

technical field [0001] The invention relates to the technical field of televisions, in particular to a multi-mode control device based on television LED lights. Background technique [0002] At present, most of the known TVs on the market use a single mode to control the on and off of the LED lights, that is, control the on and off of the LED lights through high and low levels, such as the common way that the LED lights are on when they are in standby, and the LED lights are off when they are turned on. mode. [0003] In the existing single mode, no matter what the scene is, the control of the LED light follows the rule that the LED light is on when it is in standby, and the LED light is off when it is turned on. [0004] However, there are many disadvantages in the control of LED lights following the same mode in various scenarios. For example, in shopping malls, some TV LED lights have the manufacturer's LOGO, and the manufacturer hopes that the LED lights are on to prese...

Problems solved by technology

[0004] However, there are many disadvantages in the control of LED lights following the same mode in various scenarios. For example, in shopping malls, some TV LED lights have the manufacturer's LOGO, and the manufacturer hopes that the LED lights are on to present their respective brands in the store. However, according to the rule that the LED light is off during standby, it obviously cannot meet the needs of the manufacturer; in the family, if the TV is placed in the living room, according to the rule that the LED light is on during standby, although it plays a role in reminding the user that the TV is in standby , but the use of ordinary LED lights to turn on and turn on the brightness increases the standby power consumption of the TV; Turning on the brightness will be dazzling, affecting the user's rest, and also consumes unnecessary power, increasing the standby power consumption of the product

[0005] There are limitations in controlling the on and off of LED lights in the existing single mode, which cannot meet the user's needs for LED on-off control in different scenarios, nor can it meet the requirements for adjusting the brightness of the LED on and off in different scenarios.
