Embodiment 1

[0034] An LED module, comprising: a lens 12, a wafer-level packaged LED light source, and a substrate 14 (the wafer-level packaged LED light source is arranged on the substrate 14, and the wafer-level packaged LED light source is relatively small, and the number is not marked in the figure), and The radiator 15 is provided with a substrate 14 , the substrate 14 and the radiator 15 can be directly connected or connected through a medium, and the lens 12 is provided with a convex cavity 121 . A sealed and waterproof space is formed between the convex cavity 121 of the lens 12 and the heat sink 15 for placing the WLP LED light source, and the substrate 14 is fixed to the heat sink 15 . A waterproof sealing ring 13 is arranged between the lens 12 and the radiator 15, which helps to improve the waterproof effect.

[0035] The wafer-level packaged LED light source can be soldered on the substrate 14, and the substrate 14 includes one of a metal substrate and a ceramic substrate.

Embodiment 2

[0043] The only difference from Embodiment 1 is that the waterproof line 21 is connected and sealed through the back sealing ring 22 .

[0044] The LED module of the present invention is provided with only one lens, and only one convex cavity is provided on the lens. A plurality of wafer-level packaged LED light sources are placed in the raised cavity. In this way, the optical ratios such as color temperature and CRI are uniformly performed on the entire LED module to improve the optical performance of the entire LED module. Since this LED module can install multiple LED particles in a raised cavity, and fill the cavity with a refractive index matching liquid to improve light efficiency, the light efficiency of a single LED module can be greatly improved, and it can be used as a Applications such as car lights, greatly improving the application scenarios of LED modules.

Abstract

The invention discloses an LED module which comprises a lens, a plurality of wafer level packaging LED light sources, a substrate and a radiator. The substrate is arranged on the radiator, and the substrate can be connected with the radiator directly or through a medium. A protruding cavity is formed in the lens, a sealed waterproof space for containing the wafer level packaging LED light sources is arranged between the protruding cavity of the lens and the radiator, and the substrate is fixed to the radiator. Compared with the prior art, the LED module is only provided with one lens which is only provided with one protruding cavity, the wafer level packaging LED light sources are arranged in the protruding cavity, optical matching of color temperatures, color rendering indexes and the like can be performed on the whole LED module, the optical performance of the whole LED module is improved, the application occasions of the LED module can be expanded, the requirement for the light sources is lowered, and cost is reduced.

Description

technical field [0001] The invention relates to the technical field of lighting lamps, in particular to an LED module. Background technique [0002] With the development of LED chip technology and packaging technology, more and more LED products are used in the field of lighting, especially high-power white LEDs. Due to the characteristics of high light efficiency, long life, energy saving and environmental protection, suitable dimming control, and no mercury and other pollutants, LEDs have become a new generation of lighting sources after traditional light sources such as incandescent lamps and fluorescent lamps. [0003] However, the current LED modules have the following defects: [0004] First of all, the existing LED modules have many manufacturing steps, and the light-emitting layer needs to be disposed on the substrate first and then soldered to the substrate, which makes the manufacturing process complicated. Moreover, the shape of the current LED module is usually...
