Problems solved by technology

[0003] In the prior art, the lens assembly is usually connected to the heat sink by means of screws, buckles, etc. This connection method is cumbersome to install, and is prone to looseness and unreliable connection, thus affecting the connection between the lens assembly and the heat sink. The sealing performance is poor, and the sealing effect is poor; in addition, the lens assembly and the heat sink are connected by screws and buckles, which is a point-loaded connection method. The force points are limited, and the force area is small and uneven, making the connection Insecure, poor sealing effect

Embodiment 1

[0056] refer to Figure 1-2 , this embodiment provides an LED module, which includes a lens assembly, a base 2a and a light source assembly 3a, wherein the lens assembly is provided with internal threads, and the base 2a is correspondingly provided with external threads that match the internal threads A closed accommodation space is formed by threaded connection between the lens assembly and the base 2a; at the same time, a sealing ring is provided at the portion between the threaded connection between the base 2a and the lens assembly and the accommodation space; The light source assembly 3a is located in the accommodating space, and the light source assembly 3a is arranged on one side of the base 2a. Specifically, the light source assembly 3a can be composed of a substrate and several LED illuminants arranged on the substrate. The substrate can be, for example, a PCBA. Of course, the specific structural form of the light source assembly is not limited to this, and it can als...

Embodiment 2

[0089] refer to Figure 6 , this embodiment provides an LED module, including a lens assembly, a base 2b and a light source assembly 3b, the lens assembly is installed on the upper end surface of the base 2b, and the two are screwed together to form a closed accommodating space, the light source The assembly 3b is located in the accommodating space, and the lower end of the base 2b is provided with several fins for heat dissipation.

[0090] In this embodiment, the lens assembly is a light distribution lens 1b, and a raised light distribution structure 106 is arranged on its upper end, so that the present invention can be applied to street lamps, and can also be used in other lamps that require light distribution, which will not be described here. Restrictions: The convex light distribution structure 106 of the lens 1b is asymmetrical, and the installation direction of the lens 1b in the circumferential direction can be determined according to the requirements of the light dir...

Embodiment 3

[0093] refer to Figure 7-8 , this embodiment provides an LED module, which includes a lens assembly, a base 2c and a light source assembly 3c, the lens assembly is installed on the upper end surface of the base 2c, and the two are screwed together to form a closed accommodating space, The light source assembly 3c is located in the accommodating space, and a plurality of fins are arranged on the lower end of the base 2c to form a heat sink for heat dissipation.

[0094] In this example, if Figure 7 As shown in , the lens assembly is composed of a lens 1c and a lens retainer 8, wherein the lens retainer 8 is preferably made of metal, so that it has good strength and prevents damage such as cracks. The lens 1c has an edge portion and an upwardly convex lens portion with respect to the radial circumferential surface of the edge portion, wherein the radial dimension of the edge portion is larger than that of the upwardly convex lens portion, and the edge portion faces the base 2...

Abstract

The invention discloses an LED module, which comprises: a base, a lens assembly and a light source assembly, wherein the lens assembly is provided with an internal thread, and the base is correspondingly provided with an external thread matching the internal thread. A closed accommodation space is formed through screw connection between the lens assembly and the base; at the same time, a sealing ring is also provided at the portion between the screw connection of the base and the lens assembly and the accommodation space; The light source assembly is located in the accommodating space, and the light source assembly is arranged on one side of the base. In the LED module provided by the present invention, the threaded connection is adopted between the lens assembly and the base, so that the force-bearing surface between the lens assembly and the base is enlarged and the force is uniform, so that the connection between the lens assembly and the base is firm and the sealing is good , and the installation and disassembly between the base and the lens assembly is more convenient; at the same time, a sealing ring is provided at the connection between the lens assembly and the base, so that there is a better sealing effect between the lens assembly and the base.

Description

technical field [0001] The invention relates to the technical field of lighting device design, in particular to an LED module and a lighting device. Background technique [0002] LED lamps have the advantages of energy saving, long life, good applicability, short response time, and environmental protection, and are the development direction of the lamp industry. The LED module is an indispensable part of the LED lamps. Usually, the LED module is composed of a lens assembly, a light source assembly and a radiator. Between lens assembly and heat sink. [0003] In the prior art, the lens assembly is usually connected to the heat sink by means of screws, buckles, etc. This connection method is cumbersome to install, and is prone to looseness and unreliable connection, thus affecting the connection between the lens assembly and the heat sink. The sealing performance is poor, and the sealing effect is poor; in addition, the lens assembly and the heat sink are connected by screws...
