Problems solved by technology

At present, high-power LED lamp products on the market have yellow circles or halos around the illuminated area. The halo will reduce the lighting effect and form shadows in the illuminated area. This will cause the LED lamps with halos to be unable to illuminate Applications in areas with high color requirements
The high-power LED lamp products produced by the current production method mainly have the following disadvantages: the irradiated light has a lot of variegated colors, the light shape irradiated by supporting secondary optics is difficult to control, and the treatment of the yellow circle may be derived to the application direction, etc. Wait

Embodiment Construction

[0019] The following will combine Figure 1 to Figure 6 The present invention is further described: a method for manufacturing a halo-free high-power LED lamp, which is mainly realized by the following methods:

[0020] The first step: solid crystal.

[0021] In this step see image 3 The chip 6 is bonded and fixed on the copper column 7 installed on the support 2 by silver glue, and the support 2 is formed by PPA plastic material, and the copper column 7 can help the chip 6 to dissipate heat.

[0022] Step Two: Soldering the Wires.

[0023] In this step see Figure 4 That is, the four electrodes on the chip 6 are connected to the two positive and negative electrodes provided on the positive and negative pins 3, so that the LED lamp forms an electrical circuit.

[0024] The third step: point fluorescent powder.

[0025] In this step see Figure 5 , that is, smear the fluorescent glue 8 composed of phosphor powder and colloidal silicon on the wafer 6, so that the fluoresc...

Abstract

The invention provides a method for producing a large-power LED lamp without a halo, which comprises the steps of: firstly, fixing a wafer, i.e. the wafer is fixed on a copper column which is arranged on a bracket by splicing with elargol; secondly, welding a wire, i.e. the anode and the cathode of the wafer are connected with two welding pans of a pin, so that the LED is formed into an electric loop; thirdly, pointing fluorescent powder, i.e. the wafer is coated with fluorescent gel which consists of the fluorescent powder and the colloidal silica, so that the fluorescent gel is covered on all wafer to achieve a good light emission effect; and fourthly, sealing outer sealing gel, i.e. a transparent outer sealed lens is internally injected with the sealing gel, the sealing gel is further added with a chemical industrial dispersing agent, and the other impure lights and colors are removed by the chemical industrial dispersing agent.

Description

technical field [0001] The invention relates to a method for manufacturing a halo-free high-power LED lamp. Background technique [0002] High-power LED lamps are now widely used in the lighting field due to their very strong energy-saving effect and lighting brightness. At present, high-power LED lamp products on the market have yellow circles or halos around the illuminated area. The halo will reduce the lighting effect and form shadows in the illuminated area. This will cause the LED lamps with halos to be unable to illuminate Applications in areas with high color requirements. The high-power LED lamp products produced by the current production method mainly have the following disadvantages: the irradiated light has a lot of variegated colors, the light shape irradiated by supporting secondary optics is difficult to control, and the treatment of the yellow circle may be derived to the application direction, etc. Wait.
