Manufacturing method of LED device

Abstract

The invention relates to the technical filed of a production method of LED products, in particular to a manufacturing method of an LED device. The manufacturing method comprises the following steps: 1, manufacturing a bracket which comprises a main body and a probe, wherein the main body and the probe respectively serve as two electrodes of a power supply; 2, fixing LED chips on the bracket, wherein the LED chips are distributed in a 360-degree space and on a top surface; 3, welding lines on the LED chips to form a circuit connection with the LED chips and the bracket, wherein the welded lines use gold lines; 4, spotting fluorescent powder on the LED chips; 5, baking the products; 6, utilizing a model shaping mode to package the semi-finished products on which the LED chips are arranged on the bracket by sealing wax; and 7 detecting and screening the products. The LED products produced by the invention can realize all-round luminescence, thereby overcoming the defect that the existingall-round illuminating LED device products are difficult to realize top part luminescence.

Description

Technical field: [0001] The invention relates to the technical field of production methods of LED products, in particular to a production method of LED devices. Background technique: [0002] As we all know, traditional incandescent lamps have high energy consumption and very low energy utilization rate. Only less than one tenth of the energy is converted into light energy, and the rest is wasted as heat energy. So people have been trying to find ways to replace incandescent lamps with new light sources. Therefore, energy-saving lamps came into being. Because it is relatively cheap and easy to make, it has been widely used and has a tendency to gradually replace incandescent lamps. Energy-saving lamps use the principle of electronic excitation to emit light. Compared with incandescent lamps, energy-saving lamps have the advantage of saving electricity. But one disadvantage of energy-saving lamps is that energy-saving lamps contain mercury, and mercury plays an intermediar...

AI Technical Summary

Problems solved by technology

However, LED lights also have certain defects: due to the strong directionality of the light emitted by the LED chip, its illuminated area is limited, unlike incandescent lamps and energy-saving lamps where the light source is divergent.

It can be seen that when all the LED chips 02 are connected in parallel, the resistance of the entire LED lamp will decrease, resulting in a larger operating current I, which will further increase the heat generated by the LED.
