Problems solved by technology

[0002] The chip of the existing LED light source is directly connected to the bracket to form a straight line connection. In this way, when the LED light source works for a long time, high temperature will be generated. Due to the physical principle of thermal expansion and contraction, the wire will be pulled away, resulting in damage to the LED light source.

Abstract

The invention discloses an LED light source. The LED light source comprises a bracket; a chip is arranged on the upper end face of the bracket; one side of the upper end face of the chip is electrically connected to the bracket through a flat ear arc bonding wire; two ends of the flat ear arc bonding wire are connected to the chip and the bracket through a solar ball; and the flat ear arc bondingwire is configured to be a bonding wire, the upper end of which is curved into a flat ear structure. The LED light source is reasonable in structure and high in practicability; the chip is connected with the bracket through the flat ear arc bonding wire; connection is firm; and furthermore, the flat ear arc bonding wire is good in extensibility and resistance to heat expansion and cold shrinkage,and difficult to break.

Description

technical field [0001] The invention belongs to the technical field of LEDs, and in particular relates to an LED light source. Background technique [0002] The chip of the existing LED light source is directly connected to the bracket to form a straight connection, which will generate high temperature when the LED light source works for a long time. Due to the physical principle of thermal expansion and contraction, the wire will be pulled away, resulting in damage to the LED light source. Contents of the invention [0003] The object of the present invention is to provide an LED light source to solve the problems raised in the above-mentioned background technology. [0004] In order to achieve the above object, the present invention provides the following technical solutions: an LED light source, including a bracket, the upper end surface of the bracket is provided with a chip, one side of the upper end surface of the chip is electrically connected to the bracket through...
