Abstract

The utility model relates to a light-emitting diode. A pin is firmly connected at the bottom end of a illuminant part, the other end of the pin is connected with a terminal plate, a plug pin extended to the direction away from the illuminant part is formed on one side of the terminal plate, the length of the plug pin can be pre-designed in various specification lengths, therefore the light-emitting diode can be arranged in a step shape on a printed circuit board, and the contacting area between the plug pin and the printed circuit board is small, the welding time is relatively shortened, thus the production time can be reduced, and the production efficiency is enhanced.

Description

Light-emitting diode

Technical field

The utility model is a kind of light-emitting diode, provides a kind of light emitting diode construction that uses terminal plate and printed circuit board (PCB) to mutually combine.

Background technology

Light-emitting diode (Light Emitting Diode, LED) has the advantage that to send high light and save power supply, therefore LED is widely used on the lighting apparatus, and that LED has is multiple different classes of, and wherein SNAPLED more is used in the illumination of transport facility widely.

Existing SNAPLED has illuminating part and pin, and pin has radiating part and weld fixation part, and radiating part is mutual vertical the connection with weld fixation part, and this pin forms the L-shaped lamellar body of section, and the end of the radiating part of pin is affixed mutually with the bottom of illuminating part.

When being assembled into light fixture, the weld fixation part of SNAPLED can be welded in the printed circuit board (PCB) place, again this printed circuit board (PCB) is arranged in the housing with reflecting piece, so finish the assembling of light fixture.

Yet present light fixture is with stepped arrangement with SNAPLED, so relative printed circuit board (PCB) also will adopt stepped design, yet the kind of light fixture is to be difficult to calculate, just have at set intervals in response to the market demand, and the light fixture that exploitation makes new advances, so the assembled arrangement of printed circuit board (PCB) will be had some change along with new light fixture, for in response to this change, the manufacturer that produces light fixture just must develop new mould to produce the printed circuit board (PCB) of stepped arrangement, new mould is promptly represented the increase of manufacturing cost, for manufacturer, quite do not meet its economic benefit.

In addition, the area of the weld fixation part of SNAPLED is bigger, so need the long solid welding time, for manufacturer, the long solid welding time can extend the production time, and reduces production efficiency.

Comprehensively above-mentioned, existing SNAPLED has influences operating efficiency and the shortcoming that can't change along with the variation of light fixture.

Summary of the invention

Because the inconvenience on the aforesaid prior art, the utility model is a kind of light-emitting diode of design, providing a kind of terminal plate and printed circuit board (PCB) of utilizing mutually combines, and utilize the terminal plate of pin with different length, and make light-emitting diode be able to stepped arrangement on printed circuit board (PCB), and by the pin that has than small area of contact, make that the solid welding time between light-emitting diode and the printed circuit board (PCB) is shortened, promote production efficiency by this, save manufacturing cost and reduction design cost and time.

For achieving the above object, the technological means that the utility model adopted is a kind of light-emitting diode of design, it has illuminating part and terminal plate, the bottom of illuminating part is connected with pin, terminal plate is affixed mutually with the end in addition of pin, and a side of terminal plate is formed with towards the pin away from the projection of illuminating part direction.

Advantage of the present utility model is: utilize the pin of terminal plate to be connected solid welding with printed circuit board (PCB), and the contact area between pin and the printed circuit board (PCB) is less, so can in the short time, light-emitting diode be welded in the printed circuit board (PCB) place, so can reduce the production time, and promote production efficiency.

The length of pin can design multiple different specification length in advance, when different demand, can directly take the light-emitting diode of the pin with Len req, reduces design cost and time by this.

In addition, utilize the design of the pin of this different length, and make when Design of Luminaires is had some change, can remove the puzzlement of redesign and mfg. moulding die from, so can save manufacturing cost.

Embodiment

The utility model is a kind of light-emitting diode, please cooperate with reference to shown in Fig. 1-2, and it has illuminating part 10, pin 11 and terminal plate 15;

Illuminating part 10, it can send light;

Pin 11 has mutual radiating part connected vertically 12 and connecting portion 13, makes pin 11 form the L-shaped lamellar body of section, and the end of the radiating part 12 of pin 11 is affixed mutually with the bottom of illuminating part 10, and connecting portion 13 is formed with perforation 14;

Terminal plate 15, its end face is formed with the protruded stigma 16 towards illuminating part 10 direction projections, protruded stigma 16 is the perforation 14 that run through pin 11, and utilize impact style, and make the end of protruded stigma 16 form flat, by this that terminal plate 15 and pin 11 is affixed mutually, a side of terminal plate 15 is formed with towards the pin 17 away from illuminating part 10 direction projections.

Please cooperate with reference to shown in the figure 3-4, pin 17 is to be inserted in printed circuit board (PCB) 20 places, and printed circuit board (PCB) 20 and pin 17 carried out solid welding, because the contact area between pin 17 and the printed circuit board (PCB) 20 is less, so can in the short time, light-emitting diode be welded in printed circuit board (PCB) 20 places, for production firm, the shortening of solid welding time is the reduction of production time, and the reduction of production time can make that production efficiency is promoted.

Please cooperate with reference to shown in Figure 5, it is a plurality of embodiment for light-emitting diode, the length of pin 17,17A, 17B can be increased according to actual demand, when the design of the light fixture of installing light-emitting diode is had some change, pin 17,17A, 17B that suitable length only need be selected to have by production firm are inserted in printed circuit board (PCB) 20 places and get final product, so production firm does not just need the arrangement of die sinking designing printed circuit board 20 again, only need utilize pin 17,17A, 17B just can make the stepped arrangement of light-emitting diode, so can save manufacturing cost with different length.

In addition, the length of pin 17,17A, 17B can design multiple different specification length in advance, when assembling, can directly take the pin 17 with Len req, the light-emitting diode of 17A, 17B by this, reduces design cost and time by this.
