Abstract
The invention discloses an LED (light-emitting diode) ceramic packaging material, which is prepared by calcining the following components: 6-8 parts of nano-magnesia, 10-12 parts of chromium sesquioxide, 10-15 parts of barium hydroxide, 5-6 parts of sodium hydroxide, 5-8 parts of potassium hydroxide, 3-5 parts of aluminum hydroxide, 5-8 parts of copper chloride, 80-100 parts of kaolin, 3-5 parts of zinc oxide, and 5-8 parts of calcium carbonate. The LED ceramic packaging material is low in manufacturing cost and uniform in material distribution, therefore, the packaging material is extremely applicable to the large-batch technologic production of finished products; and through the reasonable allocation of the components, the peak of a reflectance curve of a finished product is adjusted to be close to a wavelength of 420 nm, and a strong absorption peak which coincides with the visual characteristics of human eyes exists from purple light to an ultraviolet area, thereby improving the light output efficiency of the LED material.
Description
Technical field
The present invention relates to a kind of stupalith, particularly relate to the ceramic packaging material that a kind of LED is special.
Background technology
At present, existing LED encapsulation material is pottery, glass compound system and devitrified glass system mainly, and it has some weak point following:
(1) due to existing LED packaging ceramic material China, glass smelting energy consumption is high, cost is high, and is not suitable for large batch of production, causes manufacturing process complexity, cost high;
(2), in the process of fusion cast glass, the volatile substances in glass ingredient, in volatilization, volatilization degree is difficult to control, and causes the instability of material composition, causes the instability of performance.
(3) the glass dregs hardness after quenching is high, is difficult to levigate, not only adds manufacturing cost, and glass powder shape difference, and Technological adaptability is bad;
(4) light-out effect is undesirable.
Summary of the invention
The present invention is the defect in order to overcome prior art, object is to provide a kind of LED ceramic packaging material, this LED ceramic packaging material low cost of manufacture, homogenize material distributes, and be applicable to very much high volume process and manufacture a finished product, it is by the rational allocation of each component, the reflectance curve peak value of finished product is adjusted to close to 420nm wavelength, there is a strong absorption peak to ultraviolet region at purple light, match with the visual characteristics of human eye, improve the light extraction efficiency of LED material.
The technical solution adopted for the present invention to solve the technical problems is: a kind of LED ceramic packaging material, calcined by the component of following number and form: 6-8 part nano magnesia, 10-12 part chromium sesquioxide, 10-15 part hydrated barta, 5-6 part sodium hydroxide, 5-8 part potassium hydroxide, 3-5 part aluminium hydroxide, 5-8 part cupric chloride, 80-100 part kaolin, 3-5 part zinc oxide, 5-8 part calcium carbonate.
Further, be made up of the component calcining of following number: 6 parts of nano magnesias, 10 parts of chromium sesquioxides, 10 parts of hydrated bartas, 5 parts of sodium hydroxide, 5 parts of potassium hydroxide, 3 parts of aluminium hydroxides, 5 parts of cupric chlorides, 80 parts of kaolin, 3 parts of zinc oxide, 5 parts of calcium carbonate.
Or, calcined by the component of following number and form: 8 parts of nano magnesias, 12 parts of chromium sesquioxides, 15 parts of hydrated bartas, 6 parts of sodium hydroxide, 8 parts of potassium hydroxide, 5 parts of aluminium hydroxides, 8 parts of cupric chlorides, 100 parts of kaolin, 5 parts of zinc oxide, 8 parts of calcium carbonate.
In sum, LED ceramic packaging material low cost of manufacture of the present invention, homogenize material distributes, be applicable to very much high volume process to manufacture a finished product, it is by the rational allocation of each component, is adjusted to close to 420nm wavelength by the reflectance curve peak value of finished product, to have a strong absorption peak at purple light to ultraviolet region, match with the visual characteristics of human eye, improve the light extraction efficiency of LED material.。
