Abstract
The utility model discloses an LED with a thermoelectric separation full-color SMD, which comprises a base with a welding disc and a red LED chip, a blue LED chip and a green LED chip which are welded on the welding disc, wherein the red LED chip, the blue LED chip and the green LED chip are all provided with thermoelectric separation structures which are welded on the welding disc, and the red LED chip, the blue LED chip and the green LED chip are connected through like poles of gold threads. Compared with the prior art, the LED with the thermoelectric separation full-color SMD has simple structure, easy implementation and high display definition, various chips which are provided with the thermoelectric separation structures are more easy to dissipate heat, the product reliability thereof is greatly increased, and the fault rate of a lamp is lower about 300 percent than a same full-color SMD.
Description
Technical field:
The utility model relates to the thermoelectric full color surface mount LED device (SMD) that separates of a kind of tool, that be specifically related to is a kind of full color SMD LED that is arranged and form by triangle by red LED chips, blue led chip and green LED chip, and its circuit structure is thermoelectric the separation.
Background technology:
Along with improving constantly of the fast development of LED technology and people's living standard, esthetic sentiment, a kind of full-color LED display screen is shown one's talent; Because its fineness, display effect true to nature more and more are subjected to people's favor, and obtain to use widely.
Existing full-color LED display screen generally is spliced by several LED full colors SMD, and this LED full color SMD is thermoelectric one composition, and components and parts and PCB surface are pressed close to very much, little with substrate gap, poor radiation, the LED device is in the SMT process and long-time use occurs led chip easily and the pedestal pad is peeled off, and causes bad lamp.
Summary of the invention:
In order to reach good display effect and highly reliable service life, the LED full color SMD that the purpose of this utility model is to provide three kinds of diodes of red, green, blue of the thermoelectric isolating construction of a kind of tool to arrange and form by triangle, thus make the display brightness height, good, the high temperature resistant process reliability of white balance is good, the life-span is long.
The utility model is achieved through the following technical solutions: the thermoelectric full color surface mount LED device that separates of a kind of tool, comprise the pedestal of a tape welding dish and be welded on red LED chips, blue led chip and green LED chip on the pad, described red LED chips, blue led chip and green LED chip all have thermoelectric isolating construction, and be welded on the pad by triangle, link to each other by the gold thread homopolarity between described red LED chips, blue led chip and the green LED chip three.
Described pad is circular.
The utility model discloses the thermoelectric full color SMD LED that separates of a kind of tool, comprise that one has the pedestal of pad and is welded on red LED chips, blue led chip and green LED chip on the pad, described red LED chips, blue led chip and green LED chip all have thermoelectric isolating construction and are welded on the pad, link to each other by the gold thread homopolarity between described red LED chips, blue led chip and the green LED chip three.Compared with prior art the utility model simple in structure, implement easily, display resolution is high, and each chip has thermoelectric isolating construction and is more prone to heat radiation, its production reliability promotes greatly, the probability of bad lamp is than equal full color SMD low about 300%.
