Problems solved by technology

However, the current SMD infrared LED structure causes the Y-axis angle of the product to fail to meet customer needs.
[0003] Existing SMD infrared LEDs, such as figure 1 As shown, it does not have a metal reflective cup as the light-emitting reflection and refraction medium of the chip, so the light emitted by the chip has poor reflection and refraction effects due to the characteristics of the substrate material, so that the luminous radiation intensity and angle of the LED in this way are mainly determined by the secondary ball. determined by the head and the chip itself

Abstract

The invention discloses a patch infrared diode. The patch infrared diode comprises an LED chip and a substrate used for bearing the LED chip; a metal reflective cup is embedded in the light output side of the substrate; the LED chip is arranged at the cup bottom of the metal reflective cup; an optical lens is packaged on the top of the metal reflective cup; a metal contact extends outwardly from the metal reflective cup; and the metal contact is electrically connected with the wiring end of the LED chip to form a welding pin of the patch infrared diode. By adoption of the structural design, the light from the chip is reflected and refracted by the metal reflective cup to be concentrated to the optical lens, thereby improving light emitting intensity and changing the light emitting angle.

Description

technical field [0001] The invention relates to the technical field of LEDs, in particular to a patch infrared diode. Background technique [0002] With the improvement of LED technology and the reduction of cost, in the foreseeable future, SMD infrared LED light source is bound to replace the current in-line LED and become an important component in the application field of infrared LED. Due to the characteristics of small size, convenient assembly, and high assembly reliability, infrared SMD LEDs are increasingly used in a wide range of applications. However, the current SMD infrared LED structure causes the Y-axis angle of the product to fail to meet customer needs. [0003] Existing SMD infrared LEDs, such as figure 1 As shown, it does not have a metal reflective cup as the light-emitting reflection and refraction medium of the chip, so the light emitted by the chip has poor reflection and refraction effects due to the characteristics of the substrate material, so that ...
