AI Technical Summary

Problems solved by technology

Current white LEDs mainly use blue light substrates plus fluorescent materials to produce white light, and fluorescent materials are not only expensive, but also easy to attenuate. The current international highest level is only 6000 hours, which is not commensurate with the millions of hours of life of semiconductor materials! Moreover, the entire process has been blocked by patents from Japan and other countries. How to bypass its strict technical barriers and obtain the "white LED" technology with independent intellectual property rights in an economical and practical way is an urgent problem to be solved.

Embodiment 2

[0023] Embodiment 2. A multi-level series-connected parallel LED integrated die, combined with Image 6 , compared with Embodiment 1, the difference in structure is that each stage in series is composed of two single dies connected in parallel. Of course, some stages may also be configured in a parallel structure, while some stages still use the structure of a single die.

Embodiment 3

[0024] Embodiment 3. A multi-level series-head-to-tail parallel LED integrated die, combined with Figure 7 , which is formed by parallel connection of two rows of in-line multi-level series dies having the same structure as that of the first embodiment.

Embodiment 4

[0025] Embodiment 4, a white light three-stage series-connected LED integrated die has the same structure as Embodiment 1, and the three light-emitting diode dies 2, 3, and 4 integrated in series are red, green, and blue respectively. color.

[0026] The realization of the present invention can be arranged after the single LED tube core is produced, and several required single LED tube cores are integrated together in a multi-stage series structure to produce an equivalent LED tube core with a higher V F The LED integrated tube core; also can advance technology to single LED tube core production process, for example for the LED of single species or for the LED that adopts same semiconductor basic material, the realization of the present invention can be in doping, mask etc. It starts in the early stage of the process, so that the production can simplify the subsequent process and cost. In the above-mentioned embodiments, the number of integrated dies can be determined accordi...

Abstract

This invention discloses a method for integrating at least two stages of dies in the way of series on a LED base plate, in which, said stage of die is a single one or composed of multiple dies in series, parallel or a mixed way of series and parallel and the serial dies of each level have the close arrayed face-contact structure with their positive and negative faces stuck, advantage: the integration of LED dies in the way of interstage series can standardize the working voltage conveniently by selecting the number and kinds of the dies to suit different applied conditions and applying the close arrayed face contact way to realize series can save connection leads.

Description

【Technical field】 [0001] The invention relates to an LED tube core, in particular to an LED integrated tube core. 【Background technique】 [0002] Conventionally produced LED tubes are generally "single-core" products. Single-core LEDs have various structural forms, usually in-line type, patch type, etc. The positive and negative electrodes of the tube core on the substrate are respectively passed through pure gold. The wires are connected to pins protruding from the bracket. Generally, there are at least two pins on the electrical connection of the LED, one is the positive pole of the LED, and the other is the negative pole. The symbol is as follows: figure 1 shown. At present, increasing the luminous output of a single LED is a common pursuit in the industry. There are two solutions: one is to improve the luminous efficiency of the die material to achieve F Obtaining greater luminous flux without changing the situation is the main direction of huge investment in research...
