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 Radiator 15, substrate 14 is arranged on radiator 15, substrate 14 and radiator 15 can be directly connected or connected through media, lens 12 is provided with raised cavity 121, between the raised cavity 121 of lens 12 and radiator 15 A sealed and waterproof space for placing the LED light source is formed between them, 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 LED light source can be welded on the substrate 14, and the substrate 14 includes one of a metal substrate and a ceramic substrate.

[0036] The LED light source can be a wafe...

Embodiment 2

[0044] The only difference from Embodiment 1 is that the waterproof line 21 is connected and sealed through the back sealing ring 22 .

[0045] 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.

Embodiment 3

[0047] see Figure 3A and Figure 3B , which is an example diagram of an LED module with two raised cavities. An LED module, comprising a heat sink 38, a lens 31, a substrate 34 provided with an LED luminous body, the LED luminous body is arranged in the lens 31, and the lens 31 is provided with at least one convex cavity (in this example, the lens 31 There are two raised cavities 311, 312), the LED illuminant includes at least one LED illuminant unit (in this example, the LED illuminant includes two LED illuminant units 331, 332), the raised cavity 311 , 312 are in one-to-one correspondence with the LED illuminant units 331, 332, and a sealed waterproof space for placing the LED illuminant units 331, 332 is formed between the raised cavities 311, 312 of the lens 31 and the radiator, and the substrate 34 is fixed on the radiator 38 , the LED illuminant units 331 and 332 may be composed of one or several wafer-level packaged LED light sources, and of course may also be compos...

Abstract

The invention relates to the technical field of lighting lamps and discloses an LED module. The LED module comprises a radiator, a lens and a base plate provided with an LED light-emitting body. The LED light-emitting body is arranged in the lens, the lens is provided with at least one protruding cavity, the LED light-emitting body comprises at least one LED light-emitting body unit, and the protruding cavity can correspond to the LED light-emitting body unit in a one-to-one mode. A sealing waterproof space used for containing the LED light-emitting body is formed between the protruding cavity of the lens and the radiator. In the lens, the protruding cavity between the LED light-emitting body and the lens is filled with index-matching fluid used for improving the light efficiency, and in addition, filling of the index-matching fluid is performed in a glue infusing or glue dispensing mode. The LED module has the advantages of being high in reliability and high in light efficiency; due to filling of the index-matching fluid, the high-sealing waterproof grade is achieved, heat dissipation is assisted, and therefore the high reliability is achieved; and due to the index-matching liquid, light emitting media are changed into colloid from air to achieve the high light efficiency.

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 protection level of the existing LED modules is not high enough, and the heat dissipation capability is not strong enough, so the reliability is poor. [0005] Secondly, the light emitted by the LED chip of the existing LED module needs to pass through the air medium ...
