Problems solved by technology

[0006] 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.

Embodiment

[0036]The invention discloses an AC light-emitting device suitable for a chip (chip). The AC light-emitting device generates a monochromatic light source or a white light source or a non-monochromatic light source from an external AC power for use by users. The monochromatic light source or The non-monochromatic light source is displayed on the light-emitting surface of the chip in a full-time luminous state. Wherein, the alternating current is general commercial electricity, and its voltage is 110V (volts), 100V or 220V according to the electrical standards of various countries, and its frequency is 60Hz (hertz) or 50Hz.

[0037] Figure 1A and Figure 1B The structure of the AC light-emitting device of the present invention is shown in a cross-sectional view, and the structure is illustrated in the embodiment of a single AC light-emitting device in the figure. The AC light emitting device at least includes: a base material 1 , an AC microcrystalline light-emitting module 2 ...

Abstract

The invention discloses an AC luminous device and making method, which comprises the following parts: base, AC microcrystal grain luminous mode on the base with at least two microcrystals and conductive structure, wherein each microcrystal contains at least two layers of positive layer; the conductive layer connects each microcrystal electrically, which makes each positive layer of each microcrystal with AC positive-to-negative half-wave rotation illumination. The invention can illuminate evenly all the time, which minimizes the bulk of luminous device to produce better light-compositing and all-time luminating effect.

Description

technical field [0001] The invention relates to a light emitting device, in particular to an AC light emitting device and a manufacturing method thereof. Background technique [0002] 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 lighting industry and semiconductor industry in the future. Common application directions include: white light lighting, indicator lights, vehicle signal lights and lights, flashlights, LED backlight modules, projector light sources, ...
