Controller capable of optimizing panel warning display performance

Abstract

The invention discloses a controller capable of optimizing panel warning display performance. The controller comprises a shell structure combined by an upper shell and a lower shell. A control panel is arranged on the outer surface of the upper shell. A control circuit board is provided with a plurality of LED lamps on one side adjacent to the back of the upper shell, and the number and distribution positions of the LED lamps, which need warning display, correspond to the display points on the control panel. The upper shell is provided holes in positions corresponding to the display points, columnar light-guide grooves extending inwardly are formed in the back of the upper shell by using the holes as the centers, and light-guide columns made of light-transmittance materials are embedded into the light-guide grooves. The controller has the advantages that the controller is simple in structure and low in space occupation; reading during use by a user is facilitated, that is to say, the user can observe indicating information from the control panel, and the information of states such as display, warning, pre-warning and fault indicating of the controller can be observed from multiple angles.

Description

technical field [0001] The invention belongs to the technical field of controllers, and in particular relates to a controller for optimizing the reminder display performance of a panel. Background technique [0002] The casing of the existing controller generally has an indicating device, which cooperates with the light source installed inside the casing of the controller to indicate the status information of the controller such as power supply and fault. [0003] In recent years, with the continuous advancement of lighting technology, LED, as a new type of green and efficient semiconductor light source, has been applied in the field of lighting. LED light sources have the advantages of high luminous efficiency, low heat generation, power saving and long life, so their applications are becoming more and more extensive. In many electrical equipment, it is necessary to use LED lights to display the status of the equipment, so as to control the operation of the equipment. Ele...

Problems solved by technology

[0004] In the prior art, the LED light needs to be installed on the shell of the equipment so that it is easy for users to observe. Due to the welding position of the LED light or other factors, there is a certain distance between the LED light and the installation hole of the LED light on the shell of the equipment, which is not convenient for people to observe. Observation, the display effect is not good, and the LED lights will affect each other and interfere with each other during the display process
