Abstract

The utility model discloses a pin-type LED structure including a lamp board (1) and a pedestal (3). The upper surface of the lamp board (1) is provided with a plurality of LED lamps (2). Two opposite sides of the bottom of the lamp board (1) are each provided with a row of pins (4) used for being connection with a power source. One row includes four positive-electrode pins while the other row includes five negative-electrode pins. The upper surface of the pedestal is provided with pin bases (5) fitting the pins. The pin-type LED structure adopts the modularized plug-type lamp board, so that change and maintenance are facilitated. Besides, LED lamp damages caused by positive-and-negative electrode reverse connection are avoided, so that the pin-type LED structure is high in safety performance.

Description

A kind of contact pin type LED structure

Technical field

The utility model relates to a kind of contact pin type LED structure.

Background technology

Existing LED lamp, lamp pearl and lamp plate and base design for integral type, if LED lamp breaks down, the maintenance of need to taking away of so whole light fixture, thereby safeguard inconvenient.

Utility model content

Technical problem to be solved in the utility model is to provide a kind of contact pin type LED structure, and this contact pin type LED structure adopts the lamp plate of modular plug-in, be easy to change and safeguard, and can avoid both positive and negative polarity instead by and cause LED lamp to damage, safe.

The technical solution of utility model is as follows:

A kind of contact pin type LED structure, comprise lamp plate (1) and base (3), the upper surface of lamp plate (1) is provided with a plurality of LED lamps (2), the relative both sides of lamp plate (1) bottom are respectively provided with a row for introducing the contact pin (4) of power supply, one row is 4 anodal contact pins, and another row is 5 negative pole contact pins; Base upper surface is provided with the Plug pin patch bay (5) with described contact pin adaptation.

Described LED lamp (2) is 24, is 3 * 8 array arrangements.

Described LED lamp (2) is 17, adopts three ring type annular arrays of inner ring, centre circle and outer ring to arrange: inner ring is 1, is positioned at the geometric center of lamp plate (1), and centre circle is 4, and outer ring is 12.

Beneficial effect:

Contact pin type LED structure of the present utility model, adopts pin machine Plug pin patch bay to be connected between lamp plate and base, changes lamp plate very convenient, and, because anodal contact pin is different from the number of negative pole contact pin, therefore, can not cause reverse power connection, safe.
