Abstract

The invention discloses a light-emitting diode (LED) illuminating apparatus which comprises a lamp cap and an LED light-emitting unit fixedly arranged on the lamp cap. The LED light-emitting unit comprises an LED lamp board and a plurality of LED lamp beads arranged on the LED lamp board which is a column-shaped shell body. An opening is formed in one end, close to the lamp cap, of the column-shaped shell body. The LED lamp beads are evenly distributed on the outer surface of the column-shaped shell body. According to the LED illuminating apparatus, the LED lamp board in the column-shaped shell body shape and a transparent LED insulating seat are arranged, wide-angle light emitting of the LED light-emitting unit is achieved, the structure is simple, and manufacturing cost is low.

Description

technical field [0001] The invention relates to the technical field of lighting, in particular to an LED lighting device. Background technique [0002] Due to the luminous characteristics of the LED light source itself, it is difficult to achieve large-angle luminescence, which affects the lighting effect. Existing LED lighting devices mainly adopt two methods to achieve large-angle lighting: [0003] 1. With the help of optical components such as complex rhombic lenses, reflectors, and polarizing lenses, the large-angle lighting of LED lighting devices can be realized. Although this method can better realize the large-angle lighting of LEDs, various optical components The structure is complicated and the assembly is difficult, resulting in an increase in the manufacturing cost of the LED lighting device, and the light loss is serious during the reflection and transmission of the light, resulting in poor illumination; [0004] 2. Set a translucent ceramic substrate to real...
