Embodiment 1

[0031] Example 1 Glass substrate

[0032] Select a glass substrate, perform mask etching on the surface of the glass substrate, and etch out an array of periodically arranged yurt-shaped protrusions. The protrusion period is about 5 μm, the bottom surface width is about 10 μm, and the height is about 2.5 μm. An aluminum nitride layer is coated on the surface of the patterned glass substrate, and then etched with a mask to etch out a patterned structure of mesh-like voids. The voids are regular equilateral hexagons with a side length of about 3 μm, adjacent The distance between the voids is about 3 μm-7 μm. Prepare electrodes on the surface of the glass substrate, paste and fix the LED chip, connect the chip and the chip, and connect the chip and the electrode through the wire. Cover the entire LED chip and all lead wires to maximize the light output of the LED chip and effectively protect the lead wires from being touched, so as to avoid the lead wires from being disconne...

[0033] Example 2 Comparison of test data of various LED bulb lamps

[0034] We conduct experiments on the following LED bulb lamps, divided into 5 groups, each with 15 lamps, group A is a traditional LED bulb lamp, consisting of a glass cover, lens, heat sink, aluminum substrate, power supply pre-installed cavity body, plastic connectors, lamp socket interface, light source, and power supply; group B is the LED bulb lamp prepared by the method of filling the air in the sealed glass lampshade with the glass substrate according to the present invention; group C is the glass substrate on the basis of group B. The method of the present invention is etched, and etched into a patterned substrate to prepare an LED bulb; group D is an LED bulb prepared by coating a layer of aluminum nitride layer on the surface of the patterned substrate on the basis of the preparation method of group C; Group E is the LED bulb lamp prepared after patterning the aluminum nitride layer according to ...

[0038] Example 3 Thermal Analysis Experiment of LED Bulb Lamps with Different Thickness Glass Sheets

[0039] Using the same 1023 chip and different substrate thicknesses, measure the LED light source in the air respectively, then use the same light source to install the ball bulb, vacuumize and then fill the mixed gas and seal it, measure the initial luminous flux after lighting and the stabilized luminous flux respectively Luminous flux, and calculate the heat accumulation rate, deduce the influence of glass substrates with different thicknesses on LED bulb lamps.

[0040] To prepare LED light sources, select glass sheets with thicknesses of 0.3mm, 0.4mm, 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, 1.0mm, 1.1mm, and 1.2mm, 15 pieces of each thickness, each glass There are two electrodes on the substrate, the chip is fixed with fluorescent glue on the substrate, the lead is connected between the chip and the chip, and the chip and the electrode, and the fluorescent glue is direct...

Abstract

The invention relates to an LED bulb lamp and a method for manufacturing the same, and belongs to the field of LED illuminating lamp application technologies. The LED bulb lamp comprises an LED light source, a support, a lampshade, a lamp holder and a power source. The LED light source is arranged on the support, is placed in the lampshade and is connected with the power source by a power line, and the power source is fixed into the lamp holder. The LED bulb lamp and the method have the advantages that the cost can be saved, and a process for manufacturing the LED bulb lamp can be simplified.

Description

technical field [0001] The invention relates to an LED bulb lamp and a preparation method thereof, belonging to the technical field of LED lamp applications. [0002] Background technique [0003] From the perspective of the market, LED bulbs generally use spherical or quasi-spherical bulbs, and their largest market will be the civilian market, because spherical bulbs are the most used by citizens, and LED bulbs are new types of green bulbs that replace traditional incandescent bulbs. light source. [0004] From the perspective of the government, traditional incandescent lamps (tungsten filament lamps) have high energy consumption and short lifespan. Under the environment of global resource shortage, the production has been gradually banned by governments of various countries. Then the replacement products are electronic energy-saving lamps, electronic energy-saving lamps Although the energy-saving effect has been improved, due to the use of many heavy metal elements that ...
