Description

Technical Field

[0001] This utility model relates to the field of electronic component design technology, specifically a reverse polarity-protected light-emitting diode with two staggered pin distribution. Background Technology

[0002] A light-emitting diode (LED) is a semiconductor device that converts electrical energy into light energy. Its core is composed of a PN structure consisting of P-type and N-type semiconductors. When current passes through it, electrons and holes recombine and release energy to generate light radiation. It is widely used in lighting, displays, indicator lights, and signal transmission. Its high efficiency, energy saving, long lifespan, and miniaturization make it an important alternative to traditional light sources.

[0003] In the existing technology, the positive and negative terminals of light-emitting diodes are usually distinguished by the length, shape or internal structure of the leads; for through-hole LEDs, the longer lead is the positive terminal and the shorter lead is the negative terminal; for surface-mount LEDs, the polarity is determined by bottom markings such as a "T" symbol or the position of a missing corner; some packages also use differences in lead color or the size of solder joints to assist in identification; however, these methods rely on specific physical characteristics and require external observation or measurement.

[0004] When the pin lengths are the same or the package design does not provide clear markings, existing technologies make it difficult to quickly and accurately distinguish between positive and negative terminals. In such cases, traditional methods such as internal electrode observation or multimeter testing may increase application costs due to operational complexity or equipment dependence. Especially in automated soldering or high-density integration scenarios, device damage is easily caused by polarity errors. Therefore, there is an urgent need for a new reverse polarity protection structure that does not require additional tools and is applicable to various package forms.

[0005] An investigation revealed that a Chinese utility model patent discloses a light-emitting diode (publication number: CN202395029U), which includes a light-emitting diode composed of a colloid and a support. The colloid is formed by encapsulating and curing encapsulating materials at height increases of 3mm, 6mm, and 9mm, resulting in colloids of three sizes: 11.5mm, 14.5mm, and 17.5mm. Different sizes can also be added according to customer requirements to meet various needs during use, thus significantly improving customer efficiency. The support uses two pins of different thicknesses, preventing errors during production and installation soldering, facilitating identification of positive and negative terminals, and preventing reverse connection, thereby preventing adverse consequences. It has advantages such as simple structure, convenient use, improved efficiency, significant effect, easy operation, and practicality.

[0006] In existing technologies, the positive and negative terminals of a light-emitting diode are identified by the different diameters and lengths of its pins. However, in actual use, since the length of the pins is often greater than the length required by the circuit board, some pins are cut off during use. After being shortened, it is not easy to distinguish the positive and negative terminals. Therefore, additional methods of differentiation are needed, as well as methods that can be distinguished at night or in low-light conditions.

[0007] Therefore, this invention provides a reverse polarity-protected LED with misaligned dual pins to solve the above-mentioned problems. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] This invention provides a reverse polarity-protected LED with a two-pin misaligned distribution, such as... Figure 1-3 As shown, it includes a housing assembly 1, a pin assembly 2 fixedly connected to the housing assembly 1, and a light-emitting assembly 3 fixedly connected to the housing assembly 1;

[0026] The housing assembly 1 includes a nut 11, a screw housing 12 rotatably connected to the nut 11, a thread 13 formed on the screw housing 12, and a filler 14 fixedly connected to the screw housing 12.

[0027] The pin assembly 2 includes a terminal 21 fixedly connected to the filler 14, a tail cap 22 fixedly connected to the filler 14, a positive sleeve 23 fixedly connected to the tail cap 22, a negative sleeve 24 fixedly connected to the tail cap 22, and an angled 25 fixedly connected to the positive sleeve 23.

[0028] In pin assembly 2, except for terminal 21, the rest are made of luminescent material and have a night-light function.

[0029] The positive electrode sleeve 23 is in the shape of "+", and the negative electrode sleeve 24 is in the shape of "-".

[0030] Pin assembly 2 is not removable.

[0031] The light-emitting component 3 includes a lampshade 31 fixedly connected to the screw shell 12 and an LED bead 32 fixedly connected to the filler material 14.

[0032] Specifically, existing LEDs distinguish the positive and negative terminals by staggering the lengths of their pins. However, in actual use, shortening the pins makes it difficult to distinguish the positive and negative terminals, and this is even more difficult in low-light environments. Therefore, a new method of differentiation is needed.

[0033] The nuts 11, screw shells 12, and threads 13 of the housing assembly 1 are mainly used to fix the LED as a whole. The filler 14 is used to insulate and support the LED pins. The lamp cover 31 is used to focus the light, and the LED 32 emits light. The terminals 21 are staggered. On this basis, the tail cap 22, made of luminescent and insulating materials, is fixedly connected to the filler 14 at the factory and cannot be separated to prevent it from falling off later. The positive sleeve 23 is in the shape of "+", and the negative sleeve 24 is in the shape of "-" for easy differentiation. The angle 25 supports the positive sleeve 23 or the negative sleeve 24 and also protects the pins from easy breakage, extending the life of the LED.

[0034] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
