Abstract
The invention discloses a luminescent powder manufacturing method. The method is performed through following steps. Putting organic solvent or the mixture of organic solvent into a container; making the granules sticky by stirring, shaking, fusing, radiating through ultraviolet rays or by the combination of the actions and evenly attach the granules on luminescent powder; placing the luminescent power into the container again to make the granules interact with the liquid solvent in the container to produce a luminescent power layer. The luminescent power layer is placed in still to make the floating matters are uniformly afloat and reach a proper height. When the luminescent power layer reaches a proper height, add a material capable of adjusting the height of the luminescent powder layer so as to control the height of the luminescent powder layer to get finished powder. The finished powder is then placed onto a carrier to form a membrane product or a glue product. With a drying means, the membrane product or the glue product is fused together with the carrier. After that, the outmost layer of the product is coated with a transparent light preventing protection layer. In the wake of the process, the final finished product can be obtained.
Description
Technical field
Present invention is directed to a kind of manufacture method of luminescent powder, refer to that one has especially and can control luminescent powder layer thickness and the characteristic that can make luminous bisque and substrate fusion via drying mode.
Background technology
The abbreviation of LED and Light-EmittingDiode, Chinese light-emitting diode by name, generally we only say LED on the living conditions, and in life, the product utilizing LED luminescence can be seen in a lot of place usually, such as fluorescent lamp, flashlight, street lamp, display etc., but what is LED on earth?
LED is a kind of semi-conductor electricity sub-component that can be luminous, started to occur, can only send the ruddiness of low-light level in early days 1962 Christian eras, through constantly research and development, so far the light that sends of LED is throughout visible ray, infrared ray and ultraviolet, and brightness also constantly promotes, and is therefore used in various lighting device.
The advantages such as LED has high brightness, power saving, the life-span is long, volume is little, resistance to concussion, but relative also have disappearance, such as:
1.LED under high illumination usefulness is lower, and still than fluorescent lamp power consumption in general lighting purposes, some is even than Electricity-saving lamp bulb power consumption.
2. cost is high, and therefore price is relatively high.
3. because little, the poly-optical activity of LED light source area is concentrated, easily dazzling when doing lighting use, optical design divergent light source must be utilized, therefore just have anti-dazzle product on the market.
Many LED had blue problem, as long as a small amount of blue light just can allow people's spiritedness, daytime, use was fine, but was not suitable for use at night.
LED has flicker problem, and along with brightness reduces, flashing state is more obvious, easily damages eyes.
Summary of the invention
In view of this, the invention provides one to have and can control luminescent powder layer thickness and the luminescent powder manufacture method of the characteristic of luminous bisque and substrate fusion can be made via drying mode.
The invention provides a kind of manufacture method of luminescent powder, its step is as follows:
Step one a: organic solvent or its combination are poured in a container;
Step 2: utilize stirring, concussion, fusion, Ultraviolet radiation mode or its combination, granule is produced adhesion, evenly attach on luminescent powder, then be placed in the container of step one, make it produce reciprocation with the liquid flux in step one container and generate a luminous bisque;
Step 3: the luminous bisque of step 2 is left standstill and makes it evenly floating and reach a suitable height;
Step 4: when the luminous bisque of step 3 reaches suitable height, can add the relative material that has the height of the luminous bisque of adjustable, form finished powder to control the height of luminous bisque;
Step 5: the finished powder of step 4 is placed in a carrier (substrate) and above forms a film body or colloid;
Step 6: utilize drying mode, makes the film body of step 5 or colloid and carrier (substrate) merge, then in the protective layer of outermost layer spraying layer of transparent not shading, can complete final finished.
Below with reference to accompanying drawings embodiments of the present invention are described.

Embodiment
The flow chart step of the manufacture method of luminescent powder of the present invention is as follows:
Step one: pour in a container 12 by an organic solvent 11 or its combination, as shown in Figure 1, wherein, this liquid flux 11 can be water or volatile liquid, such as methyl alcohol, ethanol, propyl alcohol.
Step 2: utilize agitating mode stickiness granule 22 less for particle diameter to be evenly attached to the larger luminescent powder of particle diameter 21 rear (as shown in Figure 2), be placed in the container 12 of step one again, make it the liquid flux 11 interior with step one container 12 produce reciprocation and generate a luminous bisque 3, as shown in Figure 3 or or utilize agitating mode that granule equal for particle diameter is evenly close proximity to the equal luminescent powder of particle diameter.
Step 3: the luminous bisque 3 of step 2 is left standstill and makes it evenly floating and reach suitable height h (A+B+C), as shown in Figure 3.
Step 4: when the luminous bisque 3 of step 3 reaches suitable height h, can add the relative material 4 that has the height h of the luminous bisque 3 of adjustable, form finished powder 31 or 32, as shown in Figure 4 to control the height h of luminous bisque 3.
Step 5: utilize spray or the mode such as painting or some the finished powder 31 or 32 of step 4 are placed on a carrier (substrate) 5 and form a film body 6 or colloid 6, as shown in Figure 5.
Step 6: utilize natural air drying or the mode such as heating or Ultraviolet radiation; the film body 6 of step 5 or colloid 6 are merged with carrier (substrate) 5; again in the protective layer 7 of outermost layer spraying layer of transparent not shading; final finished can be completed; as shown in Figure 6; wherein, this protective layer 7 can be silica gel or silica gel or epoxy resin or SiO2.
