Problems solved by technology

However, because LEDs have a specific luminous angle, they cannot have a large luminous angle like traditional light sources, and a single luminous direction greatly affects the uniformity of lighting effects of lighting equipment, and is prone to halos or dark spots, causing lighting devices The lighting effect is not very ideal

Abstract

The invention discloses an LED illumination device which comprises a shell body and a plurality of LEDs; the LEDs form a plurality of LED light emitting modules sheltered in the shell body; at least two LEDs are arranged on each LED light emitting module; the light emitting modules are connected in parallel; the LEDs are distributed in outward-protruding arc face shape towards the light generating direction and form a light emitting array; at least two light emitting modules are respectively arranged on each row and line of the light emitting array; at least two of the light emitting modules have different luminous intensities.

Description

【Technical field】 [0001] The invention relates to the technical field of LED lighting, more specifically, to an LED lighting device with better lighting effects. 【Background technique】 [0002] With the development and maturity of LED technology, the performance index of LED has been greatly improved day by day. At present, the luminous efficiency of white LED has reached or even exceeded the level of luminous efficacy of ordinary incandescent lamps, and the luminous flux has also increased significantly, which has made LEDs gain a lot of attention in the field of lighting. Wide range of applications. Compared with the energy-saving lighting fixtures used by general photovoltaic power sources, LED has the outstanding advantages of long life, low heat generation, not easy to damage, low power consumption and more energy saving. People call it the fourth generation of lighting that replaces fluorescent lamps and incandescent lamps in the 21st century. light source. [0003] ...
