Abstract

The invention discloses an LED (light emitting diode) two-dimensional array light source with a flexible circuit substrate. The LED two-dimensional array light source comprises a plurality of LED chips or packaged LED light beads. The LED two-dimensional array light source is characterized by also comprising the flexible circuit substrate, wherein the flexible circuit substrate is provided with an electric conducting material with electric conducting patterns; solder mask layers are printed on the flexible circuit substrate to form a plurality of binding regions; the LED chips or the light beads are directly pasted on the binding regions, and are connected and conducted mutually through the electric conducting patterns; and array-type through holes are formed on the flexible circuit substrate. The invention provides the LED two-dimensional array light source with the flexible circuit substrate, a curve surface LED array light source type is solved, at the same time, the LED light source heat radiation effect is improved by the flexible circuit substrate and an array-type through-hole technology, thus the heat radiation capability and light dipping efficiency of a luminous light source are improved greatly, the service life is prolonged, the LED two-dimensional array light source with the flexible circuit substrate is more suitable for automatic production so as to be used by public consumers.

Description

technical field [0001] The invention belongs to the technical field of LED light sources, in particular to a two-dimensional LED array light source on a flexible circuit substrate. Background technique [0002] With the development of science and technology, LED lights have been widely used in various lighting fields due to their advantages such as high luminous efficiency, low power consumption, no need for high voltage, and high safety. The life of the LED light source is directly related to the working temperature of the node. At present, only about 50% of the electric energy of the LED lamp is converted into light energy during the working process, and the rest of the electric energy is almost converted into heat energy, which increases the temperature of the LED lamp. Reliability is halved for every 10°C increase in temperature. Heat dissipation is a big problem. If the heat dissipation is not good, it will directly lead to the decrease of LED performance and stabilit...
