AC illuminating device and manufacturing method thereof

Abstract

The invention discloses an AC illuminator and a manufacturing method thereof, the AC illuminator comprises a substrate, an AC microcrystallite illuminating module and a conductive structure, wherein the AC microcrystallite illuminating module is formed on the substrate, and is at least provided with two microcrystallites, each microcrystallite is at least provided with two active layers, and the conductive structure is electrically connected with the microcrystallites, which enables the active layers of the microcrystallites to be capable of alternately illuminating according to AC positive half wave and negative half wave. The AC illuminator utilizes that each microcrystallite is provided with at least two active layers and enables each active layer of each microcrystallite to illuminatealternately according to AC positive half-wave and negative half-wave, thereby uniformly illuminating in full time of the integral illuminating area can be realized, fluorescent powder is saved, simultaneously volume of the illuminator can be reduced, and better light mixing and full-time illuminating effect can be obtained.

Description

[0001] The present invention is a divisional application of the Chinese patent application No. 200610067030.X, the application date is March 31, 2006, and the invention name is "AC light-emitting device and its manufacturing method". technical field [0002] The invention relates to a light emitting device, in particular to an AC light emitting device and a manufacturing method thereof. Background technique [0003] Different from the light emitting principle of an incandescent lamp, the light emitting principle of a light emitting diode (LED) is mainly to apply a current to a luminous substance to achieve a light emitting effect, so the light emitting diode is called a cold light source (Cold light). Because light-emitting diodes have the advantages of high durability, long life, light weight, low power consumption, etc., and do not contain harmful substances such as mercury, solid-state lighting using LEDs has become an important research and development goal for the global...

Problems solved by technology

[0007] At the same time, since the tiny crystal grains in this patent are in the shape of an isosceles right triangle, and the length of the two sides is only about 70 microns, when pursuing product miniaturization and reducing the size of light-emitting diodes, it is bound to face the dilemma that the tiny grain size is too small to cause processing difficulties.

In addition, this patent still needs to apply the Nichia phosphor patent, and there are also problems such as high color temperature and difficult packaging control.
