Abstract

The invention discloses a light-emitting diode (LED) lighting device which comprises a luminescence portion and an installing portion, wherein the luminescence portion comprises a spherical packaging cover and a luminescence chip, the luminescence chip is arranged in the middle of the bottom of a reflection pot, and a light locking ring is arranged between the spherical packaging cover and the reflection pot. The light locking ring located between the luminescence chip and the spherical packaging cover is utilized by the LED lighting device, lateral light source loss can be reduced to a maximum extent, and a use ratio of a light source of an LED is improved.

Description

technical field [0001] The invention relates to an illuminating device, more specifically, an LED illuminating device. [0002] Background technique [0003] LED is an abbreviation taken from the three words Light Emitting Diode, which translates as "light emitting diode" in Chinese. As the name suggests, a light emitting diode is an electronic device that can convert electrical energy into light energy and has the characteristics of a diode. Existing light-emitting LEDs still have a certain amount of light leakage near the light exit, resulting in the loss of the light source of the LED. [0004] Chinese utility model patent ZL201020103814.5 discloses an improved LED lighting structure, which includes an LED body and a reflective layer. In the first embodiment of the present invention, the LED body is a two-pin direct-embedded LED, and the LED body is provided with a joint for positioning; the reflective layer is provided on the LED body and extend forward to form a cove...
