Uniformly emitting linear LED light source assembly and method

Abstract

Disclosed are a uniformly emitting linear LED light source assembly and a method thereof. The linear LED light source assembly comprises a first light strip, at least one second light strip and at least one connecting board which are all provided with a plurality of LEDs closely arranged at equal intervals, wherein the equal interval is less than 3.5 mm to realize uniform illumination. The connecting board connects the first light strip and the second light strip or connects the second light strip with another second light strip. The LED closest to the first light strip on the connecting boardand the LED closest to the connecting board on the first light strip are formed at the same pitch as the equal interval. In addition, the LED closest to the second light strip on the connecting boardand the LED closest to the connecting board on the second light strip are formed at the same pitch as the equal interval. Therefore, according to the scheme of the invention, the length of the connected light strips can be extended and increased by virtue of the invention, and the consistent uniform light-emitting characteristic can still be maintained.

Description

technical field [0001] The invention relates to an LED linear light source assembly and method that emits uniform light, in particular to an LED linear light source assembly and method that can produce uniform light and can extend the length according to usage requirements. Background technique [0002] As far as LED-related lighting technologies are concerned, LED has the characteristics of energy saving and multi-color, and has been widely used in various fields that need to emit light. The geometric structure of LED light source or LED lamp has also evolved from the original point light source to linear light source, surface light source and even three-dimensional light source arrangement according to the design and use requirements, making the application of LED light source from home appliances to 3C products. , display, lighting, lights and other fields, almost everywhere. At the same time, high-efficiency and uniform light sources have become one of the development a...

AI Technical Summary

Problems solved by technology

[0004] However, various known connectors or board-to-board connection methods, such as connector connection, jumper soldering, flexible circuit board wire row soldering, etc., are unable to meet the extension requirements due to the large connection area or no LEDs. The final linear light source can still maintain consistent luminous uniformity, especially for LED linear light sources that are closely arranged and require higher luminous uniformity, dark spots or dark areas will appear in the connection area

For example: the LED light strip connection method disclosed in US 6283612 "LIGHT EMITTING DIODE LIGHTSTRIP" is only suitable for the LED spacing greater than the size of the socket connector, otherwise it cannot meet the continuous and uniform effect of LED light emission after the light strip is connected

[0005] The disadvantage of the LED light bar connection method disclosed in US 6394623 "TRANSLUCENT FLEXIBLE ROPE LIGHT AND METHODS OF FORMINGAND USING SAME" is that the size of the copper wire connection and the double-head connector are larger than the distance between the LEDs, which cannot meet the requirements of the light bar connection. LED lighting presents a continuous and uniform effect

[0006] The "METHOD OF PRODUCTING AN LED ROPE LIGHT" of US 6860007 discloses that the metal wire is used to connect the light seat of the LED device. Because the size of the two is several times larger than that of the LED, there is no LED at the connection or the distance between the LEDs is too large to make the LED light strip Provides a continuous and uniform effect

[0007] The PCB connection method disclosed in "FPCB CONNECTION MECHANISM" of US 7097479, because the size of the connector and the cylindrical coaxial connector is several times larger than that of ordinary LEDs, cannot satisfy the continuous and uniform effect of LED light emission after the light bar is connected.

[0008] CN 203596430U's "A Connector for FPCB and Printed Circuit Board", which reveals that the size of the ZIF connector is several times larger than that of ordinary LEDs, which cannot meet the continuous and uniform effect of LED light emission after the light bar is connected

[0009] The disadvantage of the LED strip connection method disclosed in "ASSEMBLED LED LAMP STRIP STRUCTURE AND LED LAMPHAVING THE SAME FOR CONTINUOUS LIGHTING" of US 2011 / 0199768A1 is that the LED spacing at the joint is larger than the normal LED spacing in other areas, which cannot meet the requirements of the light strip connection. Rear LED lighting presents a continuous and uniform effect

[0010] CN 202056797U's "LED flexible light strip multi-directional connection board" has the disadvantage that there is no LED light-emitting component on the connection board, and it is only used for connection, which cannot satisfy the continuous and uniform effect of LED light emission after the light strip is connected.

[0011] CN 203562541U's "A LED Light Bar Connector" discloses the LED light bar connection method. Its disadvantage is that the size of the connector is too large to meet the continuous and uniform effect of LED light emission after the light bar is connected.

[0012] CN 202629944U's "LED light bar connecting device" uses PCB fixing claws and welding to connect two LED light bars. Connections for closely spaced light strips

[0013] Therefore, the above-mentioned various known technologies are not suitable for connecting LED linear light source components that are closely arranged in order to present uniform luminescence, and need to be improved.
