Description

Technical Field

[0001] The utility model relates to the technical field of LED lamps, and specifically relates to an LED lamp device. Background Art

[0002] LED lamps include components such as LED lamp beads, heat sinks, PCB circuit boards, power supplies, lenses, lamp housings, and drive circuits.

[0003] Currently, in order to connect the lens to the circuit board, an adhesive medium is usually applied to the surface of the pins of the lens. By using the adhesive property of the adhesive medium, the pins of the lens can be pasted on the circuit board, thereby realizing the connection between the lens and the circuit board. This adhesive medium can be glue.

[0004] However, since the contact surface between the pins of the lens and the circuit board is small, using glue to connect the lens and the circuit board will result in insufficient lateral pushing and pulling force of the lens. Especially when the LED lamp is in transportation, there is a certain amount of bumping or shaking during the transportation process, which makes the lens have the risk of falling off the circuit board. Summary of the Utility Model

[0005] Based on this, the purpose of the utility model is to provide an LED lamp device to solve the technical problem in the background art that when using glue to connect the lens and the circuit board, due to the small contact surface between the pins of the lens and the circuit board, the lateral pushing and pulling force of the lens is limited. Especially when the LED lamp is in transportation, there is a certain amount of bumping or shaking during the transportation process, which makes the lens have the risk of falling off the circuit board.

[0006] The utility model provides an LED lamp device, which includes a circuit board and a lens with a pin group. The pin group includes a first pin subgroup and a second pin subgroup. Each first pin in the first pin subgroup has at least one second pin in the second pin subgroup arranged opposite to it;

[0007] Wherein, the length of the first pin is longer than that of the second pin, and a plurality of limiting through holes are provided on the circuit board. Each limiting through hole is arranged opposite to each first pin. The limiting through hole is used to accommodate the first pin to limit the lateral movement of the first pin through the limiting through hole.

[0008] Further, the lens includes a substrate and the first pin subgroup and the second pin subgroup provided on the substrate.

[0009] Further, the LED lamp device further includes a plurality of trapezoidal members, and each trapezoidal member is arranged between each first pin and the substrate;

[0010] Among them, the diameter of the frustum-shaped member is greater than the diameter of the limiting through-hole, and the thickness dimension of the frustum-shaped member is equal to the length dimension of the second pin.

[0011] Further, the lens body further includes a transmissive surface portion and a reflective surface portion provided on the first side portion of the substrate.

[0012] Further, the first pin subgroup and the second pin subgroup are provided on the second side portion of the substrate;

[0013] Among them, the first side portion and the second side portion are oppositely arranged.

[0014] Further, the first pin subgroup includes a first one pin and a first two pin, and the second pin subgroup includes a second one pin and a second two pin;

[0015] Among them, taking the transverse center line of the substrate as a reference line, the first one pin and the second one pin are symmetrically arranged, and the first two pin and the second two pin are symmetrically arranged;

[0016] Taking the longitudinal center line of the substrate as a reference line, the first one pin and the second two pin are symmetrically arranged, and the first two pin and the second one pin are symmetrically arranged.

[0017] Further, the hole body depth dimension of the limiting through-hole is greater than the length of the first pin, so that there is a gap for accommodating the adhesive medium between the limiting through-hole and the first pin.

[0018] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0019] In the LED lamp device provided by the present utility model, by adopting the first pin and the second pin with inconsistent lengths, when connecting the lens to the circuit board, first insert the first pin with a longer length into the limiting through-hole. The limiting through-hole can limit the lateral movement of the first pin, so that the adhesive medium can be applied to both the first pin and the second pin, bond the outer wall of the first pin and the inner wall of the limiting through-hole, and directly bond the second pin to the circuit board. Thus, combining the adhesiveness of the adhesive medium and the limitation of the first pin by the limiting through-hole can greatly improve the lateral pushing and pulling force of the lens, and avoid the situation that the lens falls off the circuit board due to certain bumps or vibrations during the transportation of the LED lamp.

Detailed implementation manners

[0024] To facilitate the understanding of the present utility model, the present utility model will be described more comprehensively below with reference to the relevant drawings. Several embodiments of the present utility model are shown in the drawings. However, the present utility model can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the disclosure of the present utility model more thorough and comprehensive.

When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are only for the purpose of illustration.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present utility model belongs. The terms used herein in the specification of the present utility model are only for the purpose of describing specific embodiments and are not intended to limit the present utility model. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0027] Please refer to Figures 1 to 3 , which shows an LED lamp device in an embodiment of the present utility model, including a circuit board 100 and a lens 200 having a pin group. It should be noted that in some actual situations, the LED device in this embodiment is not limited to the circuit board 100 and the lens 200 having a pin group, and it may also include other components such as LED lamp beads, power supplies, and lamp housings in the prior art. Since other components are conventional prior art in this field, no special description will be given here.

[0028] In this embodiment, to solve the technical problem that when the lens 200 is connected to the circuit board 100 by using glue in the prior art, since the contact surface between the pins of the lens 200 and the circuit board 100 is small, the lateral pushing and pulling force of the lens 200 will be limited. Especially when the LED lamp is in transportation, there is a certain amount of bumping or shaking during the transportation process, which may cause the lens 200 to fall off the circuit board 100. The pin group in this embodiment includes a first pin subgroup 300 and a second pin subgroup 400. Each first pin in the first pin subgroup 300 has at least one second pin in the second pin subgroup 400 arranged opposite to it.

[0029] Among them, the length of the first pin is longer than that of the second pin, and the circuit board 100 is provided with a plurality of limiting through holes 110. Each limiting through hole 110 is arranged opposite to each first pin. The limiting through hole 110 is used to accommodate the first pin to limit the lateral movement of the first pin.

[0030] That is, by using first pins and second pins with different lengths, when connecting the lens 200 to the circuit board 100, first insert the first pin with a longer length into the limiting through hole 110. The limiting through hole 110 can limit the lateral movement of the first pin. In actual situations, adhesive medium can be applied to both the first pin and the second pin respectively. The outer wall of the first pin is bonded to the inner wall of the limiting through hole 110, and the second pin is directly bonded to the circuit board 100. Thus, by combining the adhesiveness of the adhesive medium and the limitation of the first pin by the limiting through hole 110, the lateral pushing and pulling force of the lens 200 can be greatly improved, and the situation that the lens 200 falls off the circuit board 100 due to bumping or shaking during the transportation of the LED lamp can be avoided.

[0031] It should be noted that, for the convenience of applying the adhesive medium on the first pin, in some preferred embodiments, the depth dimension of the hole body of the limiting through hole 110 is greater than the length of the first pin, so that there is a gap for accommodating the adhesive medium between the limiting through hole 110 and the first pin. By using this gap, sufficient adhesive medium can be ensured to be applied between the first pin and the limiting through hole 110 to ensure the stability of the first pin fixed in the limiting through hole 110.

[0032] In some preferred embodiments, the adhesive medium can be glue in the prior art.

[0033] In addition, the lens 200 includes a substrate 210, and a first pin subgroup 300 and a second pin subgroup 400 arranged on the substrate 210.

[0034] Specifically, the lens 200 body further includes a transmissive surface portion 220 and a reflective surface portion 230 provided on the first side portion of the substrate 210. The first pin subgroup 300 and the second pin subgroup 400 are provided on the second side portion of the substrate 210, wherein the first side portion and the second side portion are oppositely arranged.

[0035] In some preferred embodiments, to facilitate the simultaneous contact of the first pins and the second pins with the circuit board 100, the LED lamp device further includes a plurality of stepped members 500, and each stepped member 500 is provided between each first pin and the substrate 210; wherein, the diameter of the stepped member 500 is greater than the diameter of the limit through hole 110, and the thickness dimension of the stepped member 500 is equal to the length dimension of the second pin, that is, by adding the stepped member 500, when the first pin completely extends into the limit through hole 110, the second pin will directly contact the circuit board 100, so as to achieve the simultaneous bonding of the first pin and the second pin.

[0036] Furthermore, to further improve the lateral pushing and pulling force of the lens 200, in this embodiment, the first pin subgroup 300 includes a first one pin 310 and a first two pin 320, and the second pin subgroup 400 includes a second one pin 410 and a second two pin 420; wherein, taking the lateral center line of the substrate 210 as a reference line, the first one pin 310 and the second one pin 410 are symmetrically arranged, and the first two pin 320 and the second two pin 420 are symmetrically arranged; taking the longitudinal center line of the substrate 210 as a reference line, the first one pin 310 and the second two pin 420 are symmetrically arranged, and the first two pin 320 and the second one pin 410 are symmetrically arranged, that is, by limiting the positions of the first one pin 310 and the first two pin 320, the first one pin 310 and the first two pin 320 can be obliquely symmetric, so as to ensure the stability of the connection between the lens 200 and the circuit board 100 by using a small number of first pins, and the operation steps during production can be saved.

[0037] In summary, in an LED lamp device according to an embodiment of the present invention, compared with the LED lamp device in the prior art, there are at least the following beneficial effects:

[0038] In the LED lamp device provided by the present utility model, by adopting the first pin and the second pin with inconsistent lengths, when connecting the lens 200 to the circuit board 100, the first pin with a longer length is first inserted into the limiting through hole 110. The limiting through hole 110 can limit the lateral movement of the first pin, so that adhesive medium can be applied to both the first pin and the second pin respectively, and the outer wall of the first pin is bonded to the inner wall of the limiting through hole 110, and the second pin is directly bonded to the circuit board 100. Thus, by combining the adhesiveness of the adhesive medium and the limitation of the first pin by the limiting through hole 110, the lateral pushing and pulling force of the lens 200 can be greatly improved, and it can be avoided that when the LED lamp is transported, due to certain bumps or vibrations during the transportation process, the lens 200 falls off the circuit board 100.
