Abstract
A pin type LED in the prior art mostly has two pins of an anode and a cathode, and about 90% of heat of a chip is transferred onto a printed circuit board via the pins and then radiated into the surrounding air. The structure has the shortcomings of difficult dissipation of the produced heat, light attenuation and short service life. The invention discloses an LED, wherein two pins of the LED are set to be L-shaped laminar structures, thereby increasing the area of the pins, quickly radiating the heat produced during working from the L-shaped laminar anode pin and the cathode pin, further avoiding the LED from being damaged due to the production of excessively high temperature caused by heat accumulation of the chip. Simultaneously, when carrying out electrical connection on the LED, the rivet connection is directly carried out at a through hole, or the connection is carried out through a conductive connecting part, or the L-shaped laminar pins are combined and connected when designing a support, thereby further expanding the heat radiation area, reducing the PCB board, simplifying the welding process, reducing the cost and enhancing the heat radiation of the LED. The invention provides the LED with simple structure, good heat radiation effect and long service life, thereby effectively promoting the development of marketization of LED lighting.
Description
Technical field
The present invention relates to electrical category, relate in particular to a kind of LED.
Background technology
Advantages such as LED has that light directive property is good, the life-span is long, volume is little, in light weight, low voltage operating, response time are fast, no infra-red radiation, and fully represent the maximum characteristics that energy-saving and environmental protection, benefit are looked, become indispensable ornament or illuminations in people's life.Can produce a large amount of heats during the work of LED lamp, if untimely these heats are distributed, will the service behaviour of LED be exerted an influence, particularly be applied in illumination, heat radiation is a big problem, and the quality of radiating effect is directly connected to the reliability of device, LED can only be converted into luminous energy with the small part electric energy at present, and remaining 80% power conversion is a heat energy, if heat concentrates in the small-sized chip, can make the chip internal temperature overheating and damages.In the prior art, pinned LED great majority have anode and two pins of negative electrode, and the heat of chip about 90% is delivered on the printed circuit board (PCB) by pin, is dispersed in the surrounding air again.The shortcoming of this structure is that the heat that produced is not easy to dissipate, and produces the light inner feelings and shortens the life-span, so also can't really be used for the LED illumination till now.
Summary of the invention
The LED that the purpose of this invention is to provide a kind of simple in structure, good heat dissipation effect, long service life, not only reduced pcb board and simplified welding procedure, reduced cost, and by strengthening the pin area, strengthen the LED heat radiation, promote the development of LED illumination marketization effectively.
The objective of the invention is and can realize by following technical measures:
A kind of LED, two pins are set to the L laminated structure.
Be respectively equipped with one or more through hole on described two pins.
When two or two the above LED are electrically connected, connect, or the L sheet pin disjunctor of described LED is connected by conducting connecting part.
When two or two the above LED are electrically connected, directly rivet in the through hole, or connect, or the L sheet pin disjunctor of described LED is connected by conducting connecting part.
