Modularized LED (light emitting diode) lamp

Abstract

The invention discloses a modularized LED lamp. The modularized LED lamp comprises at least one LED lamp module, wherein the LED lamp module includes a secondary light distribution lens, a package case, a circuit board, and an LED chip communicated with the circuit on the circuit board, wherein the secondary light distribution lens includes a collimating lens and a flat lens arranged on the front end face of the collimating lens; the collimating lens has a fully reflecting surface on the side surface; the light emergent surface of the flat lens consists of a plurality of rectangular pyramid-shaped micro-lenses; a refraction groove for placing the LED chip is arranged on the rear end face of the collimating lens; a recess is formed on the side surface of the collimating lens close to the flat lens; a bump matching the recess is arranged on the package case; and a jack is arranged on the package case and is connected with a conducive metal part communicated with the circuit on the circuit board. The modularized LED lamp provided by the invention can be extended randomly according to requirement without limit to installation conditions, and the spliced LED lamp module has no dark zones or dark spots.

Description

technical field [0001] The invention relates to the field of splicable LED modular lamps, in particular to an LED modular lamp capable of splicing without dark areas. Background technique [0002] LED light source is playing an increasingly important role in the field of lighting in the world because of its significant advantages such as high brightness, good shock resistance and shock resistance, long service life, and high light efficiency. Countries have increased research on LED light sources. The development prospect is very impressive. [0003] The LED strip light in the prior art has a single form, a relatively narrow scope of application, and low flexibility. Basically, one type of light can only be used in one fixed position in one fixed form. The structure of LED strip lights is fixed and cannot be expanded to meet the increasingly diverse needs of the world. With the development of technology, although some connectable LED lamp groups have appeared, their innova...

Problems solved by technology

The disclosed technical solution uses connectors to make the number of LED lamp panels superimposed and spliced ​​without an upper limit, which can meet the photography needs of large illumination area and uniform illumination, but the seamless splicing between the lamp panels cannot be achieved, and at the same time, the gap between the lamp panels cannot be eliminated. The resulting dark area affects the effect of light irradiation, and there are technical defects
