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.

Embodiment Construction

[0034] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0035] The production method of this embodiment is as follows:

[0036] 1. Make the bracket 1.

[0037] See Figure 3-7 , the bracket 1 serves as the carrier of the entire LED device, which includes: a main body 11 and probes 12 fixed to the main body 11 and insulated from each other. The main body 11 is composed of the packaging platform 10 and the threaded section 111 , and a through hole is formed in the main body 11 . The main body 11 has a protrusion 100 extending from the top of the packaging platform 10 .

[0038] The above packaging table 10 includes: a boss 101 and a cylinder 102 located at the center of the boss 101 . The above-mentioned protrusion 100 extends from one corner of the top of the cylinder 102 . The cross section of the cylinder 102 is a regular polygon. In this embodiment, the cylinder 102 is a regular tetrahedron, thus realizing 360-deg...

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...
