Abstract
Description
Technical Field
[0001] This utility model belongs to the field of lighting technology and relates to a lighting fixture with LED chip arrangement with extremely small spacing. Background Technology
[0002] The lamp consists of lamp beads and lampshade. To meet the needs of use, the lamp must have good light uniformity. The lamp beads or the particle appearance of the lamp beads should not be visible on the outside of the lamp. If the lamp beads or the particle appearance of the lamp beads can be seen on the outside of the lamp, it means that the lamp has extremely poor light uniformity.
[0003] For example, existing lighting products use LED chip gaps greater than 1cm and lampshade-LED chip gaps greater than 2cm. This design, with a chip gap greater than 1cm and a distance between the LED chip and lampshade greater than 2cm, prevents the lighting from appearing grainy and achieves good light uniformity. To achieve this, the lampshade size is typically increased to widen the distance between the LED chip and the lampshade wall, or the lampshade wall is thickened. However, this results in larger lighting products, reduced portability, limited usage scenarios, decreased light transmittance, and higher costs. Utility Model Content
[0004] This invention provides a lighting fixture with LED chip arrangement with extremely small spacing, aiming to solve the problems existing in the background technology.
[0005] To achieve the above objectives, this utility model provides a lamp fixture with an LED chip arrangement with extremely small spacing, including a lampshade and an FPC flexible board installed inside the lampshade. A plurality of LED chips are arranged on the FPC flexible board, with a front-to-back gap A of 2.5cm between two adjacent front-to-back LED chips, a left-to-right gap B of 2cm between two adjacent left-to-right LED chips, and a chip-to-beam distance C of 1cm between the LED chips and the inner wall of the lampshade, thereby achieving uniform lighting.
[0006] Preferably, the LED chip has pins on both the left and right sides of the front end face and the left and right sides of the rear end face, and the pins of two adjacent LED chips arranged one in front of the other are aligned.
[0007] Preferably, the LED chip is a 5050 chip.
[0008] The advantages of this utility model over the prior art are:
[0009] This invention arranges the pins of LED beads in an aligned manner, and sets the front-to-back gap A between two adjacent LED beads to be 2.5cm, the left-to-right gap B to be 2cm, and the distance between the bead walls C to be 1cm. This design can be compatible with the lampshade of traditional lamps, and the uniformity of the lamp light will not be reduced. The light is soft, the cost is reduced, and it can meet more usage scenarios.
[0010] To more clearly illustrate the structural features and effects of this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments. Attached Figure Description

[0016] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein in the specification of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and foregoing drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.
[0017] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.
[0018] To achieve the above objectives, this utility model provides a luminaire with an extremely small-pitch LED chip array, as shown in the reference. Figure 1-3As shown, the lamp includes a lampshade 1 and an FPC flexible board 2 installed inside the lampshade 1. A plurality of LED chip patches 3 are arranged on the FPC flexible board 2. The gap between two adjacent front and rear LED chip patches 3 is set to a front-to-back gap A of 2.5cm, the gap between two adjacent left and right LED chip patches 3 is set to a left-to-right gap B of 2cm, and the distance between the LED chip patches 3 and the inner wall of the lampshade 1 is set to a chip wall distance C of 1cm, so as to achieve uniform light.
[0019] Traditional LED arrangement occupies space due to the pin positions, so the distance between two adjacent LEDs in the direction with pins (front and back) is always greater than the distance in the direction without pins (left and right). If the design dimensions are unreasonable, and the lampshade size and thickness are not designed properly, it is easy to see LEDs or LED particles on the outside, resulting in unqualified lamps.
[0020] In this embodiment, the LED chip 3 has pins on both sides of its front and rear ends, and the pins of two adjacent LED chips 3 arranged in a front-to-back configuration are aligned. The front-to-back gap A between two adjacent LED chips 3 is designed to be 2.5cm, the left-to-right gap B between two adjacent LED chips 3 is designed to be 2cm, and the distance between the LED chip 3 and the inner wall of the lampshade 1 is set to the bead-wall distance C is 1cm. At this point, the size of the lampshade 1 is shortened due to the smaller bead-wall distance C, while the wall thickness of the lampshade 1 can remain at a conventional thickness (3cm). The LEDs or their particles are not visible from the outside of the lamp, reducing the overall cost of the lamp and improving the uniform light distribution. Furthermore, when the wall thickness of the lampshade 1 decreases to 1cm, the size of the lampshade 1 shrinks, resulting in a smaller volume. The LEDs or their particles are still not visible from the outside of the lamp, further reducing the overall cost of the lamp while maintaining uniform light distribution and correcting the unreasonable design of traditional lamps.
[0021] Furthermore, the LED chip patch 3 is a 5050 chip patch, but it is not limited to the 5050 chip patch model. Other LED chip patch 3 models can also be used in this arrangement.
[0022] In summary, this utility model arranges the pins of the LED bead patch 3 in a directly aligned manner, and sets the front-to-back gap A of two adjacent LED bead patches 3 to be 2.5cm, the left-to-right gap B to be 2cm, and the bead wall distance C to be 1cm. This allows it to be compatible with the lampshade of traditional lamps, without reducing the uniformity of the lamp's light, providing soft light, reducing costs, and meeting more usage scenarios.
[0023] The technical principles of this utility model have been described above with reference to specific embodiments, which are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments; all technical solutions falling within the scope of this utility model's concept are protected. Other specific embodiments of this utility model that can be conceived by those skilled in the art without creative effort will also fall within the protection scope of this utility model.
