Problems solved by technology

[0005] 1. There is no reinforcement structure on the outer surface of the existing lens base, resulting in low structural firmness and durability. After a long period of use, the middle part of the lens is easy to form a raised bulge, resulting in deformation of the lens group;
[0006] 2. The existing buckle has a stepped structure, which makes it easy to break during the pressing process;
[0007] 3. The screw accommodating slots and wire accommodating slots set on the existing LED lens group are relatively thin. Since they are made of plastic, aging and cracking will occur after long-term use;
[0008] 4. In the lens group of some existing LED products, the buckle on the lens base has a boss at its contact with the lens base. The presence of the boss makes the groove of the liquid silicone ring here Narrowed, this structure causes liquid silicone to be easily interrupted due to the presence of barriers during dispensing

Embodiment 1

[0053] see Figure 1A , Figure 1B and figure 2 , the LED lens group provided by this embodiment includes a lens base 1, and a plurality of lenses 2 arranged on the lens base 1, a screw accommodation groove 3, a cross-shaped wire-avoiding groove 4 for accommodating electric wires, a solid The silicone ring groove 5 and the liquid silicone ring groove 6, the liquid silicone ring groove 6 is arranged on the edge of the lens base 1, the solid silicone ring groove 5 is arranged on the inner side of the liquid silicone ring groove 6, and is also included in the lens base A plurality of buckles 7 around the seat 1, the LED lens group is connected with the heat sink of the LED lighting device through these buckles 7. Wherein, according to the current commonly used design, the cross-shaped wire-avoiding groove 4 and the screw accommodating groove 3 protrude outward relative to the plane of the lens base 1 .

[0054] Wherein, the periphery of the lens base 1 adopts a thickened desig...

Embodiment 2

[0068] see Figure 5 , the structure of this embodiment is basically the same as that of Embodiment 1, the difference is that the light distribution direction indicator arrow 41' arranged on the cross-shaped wire-avoiding groove 4 is slightly smaller, and does not fill the entire cross-shaped wire-avoiding groove 4 The short side; and, the arrangement of the buckles 7 is relatively uniform: two buckles 7 are arranged in the middle of the long side of the lens base.

[0069]

Embodiment 3

[0071] see Figure 6 , this embodiment provides another LED lens group with a strengthening mechanism, wherein, its difference from Embodiment 2 lies in the following points:

[0072] The arrangement of the lenses 2 is different. In this embodiment, the total number of lenses is the same as in Embodiment 1, but the lenses 2 are arranged in two rows, and the electric wire accommodating groove 4' is a strip groove, and the light distribution direction indicator arrow 41 on it '' corresponds to its size; and is located in the middle of a row of lenses. This setting can greatly reduce the width of the lens group and the LED module, thereby saving materials; because the circuit board is narrowed, only two screws are needed for fastening, so this embodiment only sets two screw accommodation slots , see its setting location Figure 6 , basically located in the middle of the LED lens group, and four are set in Embodiment 1;

[0073] In addition, the reinforcing ribs 8' are linear, ...

Abstract

The invention discloses an LED lens set with a firm structure and good durability. The LED lens set with the firm structure and good durability comprises a lens base, lenses which are arranged on the lens base, a liquid silica gel ring groove, a solid silica gel ring groove, a plurality of screw containing grooves and wire containing grooves, wherein the liquid silica gel ring groove and the solid silica gel ring groove are formed in the edge of the lens base, screw containing grooves are formed in the lens base, the edge of the periphery of the lens base is thickened, the edge of the thickened lens base is obviously higher than the adjacent position of the inner side of the lens base, so that a circle of protrusions are formed, and the protrusions has a shape which can guide the direction of water flow. Due to the fact that the edge of the periphery of the lens base is thickened, reinforced ribs are additionally arranged, and a partition structure used for reinforcing is arranged inside each wire containing groove, firmness and durability of one LED lens are improved, and the middle of one lens can not protrude after one lens is used for a long time.

Description

technical field [0001] The invention relates to the lighting field, in particular to an LED lens group with firm structure and good durability and an LED lighting device. Background technique [0002] LED lamps have the advantages of energy saving, long life, good applicability, short response time, environmental protection, gorgeous colors, and pure luminous colors. They are the development direction of the lamp industry. [0003] The common LED bulb lamps, LED spotlights, and LED PAR lamps currently on the market are generally composed of die-cast aluminum radiators, LED lens groups, circuit boards soldered with LED light beads, LED drive power, lamp holders, etc. Wherein the circuit board is fixed on the die-casting aluminum radiator and is covered with an LED lens group, and the die-casting aluminum radiator has a cavity in which an LED driving power is housed. [0004] The existing LED lens group adopts an integrated design structure, including a lens base, a lens set ...
