Problems solved by technology

However, this unified design will cause each light-emitting module to irradiate uniformly only in the direction along the optical axis, but there will be dark areas on the mounting surface where the light-emitting modules are located, especially between two adjacent light-emitting modules. A shaded area will appear in the middle area
This situation can limit the lighting effects affecting the entire lighting installation

Abstract

The invention relates to a light-emitting module (10) which comprises a circuit board (1) provided with an edge region and a central region, at least one first light source arranged in the edge region of one plane of the circuit board (1) and at least one first optical device (3) matched with the corresponding first light source. The light-emitting module (10) is characterized in that light beams emitted by each first optical device (3) towards a lateral external space outside the edge region of the circuit board (1) are more than light beams emitted by the same first optical device (3) towards the central region of the circuit board (1). In addition, the invention further relates to an illuminating apparatus and a lamp box including the light-emitting module.

Description

technical field [0001] The invention relates to a light emitting module, an illuminating device and a light box including the light emitting module. Background technique [0002] LED lighting modules have the advantages of energy saving and high efficiency, so they occupy a dominant position in today's lighting field. With the development of lighting technology, retrofit lamps using LEDs as light sources have gradually replaced fluorescent lamps and are widely used in various occasions. For example, in the advertising industry, it is necessary to install multiple LED light-emitting modules in an electronic billboard or display lamp in a linear arrangement to achieve a predetermined lighting pattern, where it is inevitable between two adjacent light-emitting modules with a certain spacing. [0003] In the prior art, the same lens is often installed on each light source of the light emitting module, thereby improving lighting efficiency. However, this unified design will ca...
