Embodiment 1

[0023] Depend on Figure 1-Figure 4 A method for adjusting the irradiation uniformity of a radiation source includes the following steps:

[0024] (1) Use the illuminance sensor 5 to detect the illuminance of the measuring point 4 in the box body 3, the method is as follows: place the illuminance sensor 5 at the measuring point 4 in the box body 3, and cover the box opening of the box body 3 with a transparent glass 2 , the blue light emitted by a blue light source penetrates the transparent glass 2 into the box 3 and irradiates the illuminance sensor 5, and the illuminance sensor 5 detects the illuminance of the measuring point 4 where it is located;

[0025] The box body 3 is the box body of the temperature and humidity box, and the box body 3 is a rectangular box body. 4 is a point on the upper surface of the bottom plate of the box body 3, and the illuminance sensor 5 rests on the upper side of the bottom plate of the box body 3 and is located on the measuring point 4.

Embodiment 2

[0038] Depend on Figure 5 The aging device shown is matched with the method for adjusting the irradiation uniformity of the radiation source described in Embodiment 1. After completing steps 1-3, the aging device described in Embodiment 2 can be obtained.

[0039] An aging device includes an aging box and a blue light source correspondingly arranged outside the aging box.

[0040] The aging box is a temperature and humidity box, and the aging box includes a box body 3 with a box opening, the box body 3 is a rectangular box body, and a transparent glass 2 covers the box opening.

[0041] The mouth of the box is the top opening of the box body 3, and samples are arranged in the box body 3, and the samples are arranged in a rectangular array. Inside, on the upper side of the bottom plate of the box body 3, the sample is LED fluorescent glue or silica gel.

[0042] A reflective material 6 is arranged on the inner wall of the box, and at least two kinds of reflective materials 6...

Abstract

The invention discloses a method for adjusting the irradiation uniformity of a radiation light source of an aging device and an aging device, which belong to the technical field of aging of LED fluorescent glue. A method for adjusting the uniformity of irradiation of a radiation source of an aging device comprises the following steps: (1) Use the illuminance sensor to detect the illuminance of the measuring point in the box, (2) adjust the illuminance of the measuring point by setting reflective materials on the inner wall of the box, (3) take the illuminance sensor out of the box, and place the sample in the box for measurement At the point, the light emitted by the blue light source enters the box through the transparent glass and illuminates the sample. The aging device is matched with a method for adjusting the irradiation uniformity of the radiation light source of the aging device. The invention relates to a method for adjusting the irradiation uniformity of a radiation light source of an aging device and an aging device, which can irradiate LED light glue to make it age.

Description

technical field [0001] The invention belongs to the technical field of LED fluorescent glue aging, and in particular relates to a method and an aging device for adjusting the irradiation uniformity of a radiation light source. Background technique [0002] Temperature, humidity and blue light exposure are the three main factors affecting the aging of LED fluorescent adhesive materials. However, the existing aging equipment on the market cannot apply the above three stress loads at the same time. Contents of the invention [0003] The object of the present invention is to provide a method for adjusting the irradiation uniformity of a radiation source and an aging device for irradiating LED photoresist. [0004] In order to achieve the above object, the present invention adopts the following technical solution: a method for adjusting the uniformity of radiation light source irradiation, including the following steps: (1) using the illuminance sensor to detect the illuminanc...
