Colorlight and Debon Lighting announce LED display and lighting patents

Recently, Colorlight and Debon Lighting announced the latest LED display and lighting related patents.

Colorlight has obtained two LED display patents

On November 29, the State Intellectual Property Office announced that Colorlight has obtained two patents, namely "a method, device and system for sorting light points in special-shaped LED displays" and "a method, device and system for correcting viewing angle differences in LED displays".

Among them, "A sorting method, device and system for light points in special-shaped LED display screens", authorization announcement number CN114927090B, application date is May 2022.

The patent abstract shows that the present invention discloses a method, device and system for sorting light points in a special-shaped LED display screen. The method includes: determining the number of corner points of the special-shaped LED display screen and the two bottom corner points through a convex hull algorithm, and performing perspective transformation on the first image of the special-shaped LED display screen based on the two bottom corner points to obtain the second image after perspective transformation;

Determine the surrounding light points and the preset area of each light point to be sorted in the second image, traverse all the light points in the special-shaped LED display screen, and determine the positional relationship between the corresponding surrounding light points and the light points to be sorted, until the rows and columns of all light points are determined to sort the light points in the special-shaped LED display screen. It can determine the point coordinates during perspective transformation based on the corresponding corner points of the special-shaped LED display, perform perspective transformation on the special-shaped screen, and determine the rows and columns of the light points based on the relationship between each light point and the surrounding light points and the preset area, thereby sorting the light points in the special-shaped screen to facilitate subsequent light point correction work.

"A method, device and system for correcting the viewing angle difference of LED display screens", authorization announcement number CN114927092B, application date is May 2022.

The patent summary shows that the invention discloses a method, device and system for correcting the viewing angle difference of an LED display screen, which can monitor the camera shooting angle in real time, process and display the display screen of the LED display screen in real time, ensuring that the shooting screen eliminates the viewing angle difference and ensures the continuity of the picture.

According to data, Colorite is mainly engaged in the business of professional display control products. The company's products are mainly divided into three categories: LED display control systems, video processing equipment, and cloud network players, which can realize various functions such as display control, editing and processing, and transmission analysis of video signals and image data.

Driven by the growth in overseas market demand, in the first three quarters of this year, Colorite's revenue was 568 million yuan, a year-on-year increase of 33.87%; net profit attributable to the parent company was 110 million yuan, a year-on-year increase of 42.51%.

Debang Lighting has obtained two LED lighting patents

On November 29, according to the announcement of the State Intellectual Property Office, Hengdian Group Debang Lighting Co., Ltd. obtained a patent titled "A LED panel light corner protection structure and its implementation method", authorization announcement CN115231128B, and the application date is August 2022.

The patent abstract shows that the present invention discloses a corner protection structure for an LED panel lamp. By arranging a first support buffer edge and a second support buffer edge, after the corner protection structure is placed on the corner of the lamp body, a certain distance is separated between the lamp body and the carton, forming a buffer zone, thereby improving the safety of transportation.

On November 30, Debon Lighting obtained a patent titled "A DIP LED Color Adjustment Circuit with Uniform Light Efficiency Power", with the authorization announcement number CN220108258U, and the application date is June 2023.

This patent discloses a method that uses the characteristics of different brightness of parallel low color temperature lamp group and high color temperature lamp group under different current conditions, and controls the voltage difference and current characteristics of the low color temperature lamp group and the high color temperature lamp group through diodes and resistors, so that the brightness of the low color temperature lamp group and the high color temperature lamp group is different to achieve color temperature adjustment.

Information shows that Debon Lighting focuses on the general lighting and vehicle parts industries. The company's products cover three categories: civil lighting products, commercial lighting products and vehicle products, which are widely used in civil and commercial fields.

In recent years, Debang Lighting's automotive business has continued to grow. In the first three quarters of this year, Debon Lighting achieved revenue of 3.643 billion yuan, a year-on-year increase of 1.57%; net profit attributable to the parent company was 278 million yuan, a year-on-year increase of 26.22%.
