Problems solved by technology

Therefore, there are limitations when using the same gauge 1b to detect LED light sources 203 of different sizes and shapes, and the problem of light blocking cannot be completely eliminated, resulting in underestimated measured luminous flux values, and the gauge 1b is only suitable for use with longitudinal plates. 2132 and 2133 have a small number of light-emitting diode light source 203 types. Obviously, the measurement quality and application level of the measuring tool 1b still have limitations and deficiencies.

Embodiment Construction

[0069] Referring to FIG. 4 to FIG. 7 , the light-emitting diode measuring tool of the present invention will be further described.

[0070] FIG. 4 is a top view and a schematic assembly cross-sectional view of the first embodiment of the present invention. The measuring tool 1 mainly includes a shell portion 10 and a testing portion 20 .

[0071] The shell portion 10 is a hollow cylinder with at least one end opening to install the test portion 20. The outer peripheral wall of the cylinder extends axially from the opening to form a thinner front section 101 and is formed between the remaining thicker rear section 102 walls. The stepped surface 103 at right angles. The size of the outer peripheral wall of the front section 101 matches the shape and the inner peripheral wall of the test insertion port (not shown) of the integrating sphere, and abuts against the outer end surface of the test insertion port with the step surface 103 to achieve the testing part 20 Position the lig...

Abstract

A light-emitting diode detection measuring implement is used for detecting a light-emitting diode light source and comprises a shell part and a test part. The test part is installed on the shell part and comprises a carrier plate. The carrier plate is used for bearing the light-emitting diode light source to enable the bottom surface of the light-emitting diode light source to be arranged on the carrier plate in an attached mode, and the light-emitting surface of the light-emitting diode light source deviates from the carrier plate. The test part further comprises a hose and a vacuum pump. The carrier plate is provided with at least one air hole corresponding to the light-emitting diode light source, and the hose is communicated with the air hole and the vacuum pump, so the vacuum pump can be used for enabling the light-emitting diode light source to be adsorbed to the carrier plate.

Description

technical field [0001] The invention relates to a light-emitting diode detection measuring tool, in particular to a light-emitting diode attached to the area to be tested through suction, which has the advantages of not blocking light, easy operation, and high accuracy during detection, and is suitable for different sizes, shapes, and structures. , type of light-emitting diodes for a universal measuring tool. Background technique [0002] The light and power measurement system for detecting light-emitting diodes (LED, Light Emitting Diode) is to install the measuring tool carrying the light source of the light-emitting diode into the integrating sphere, and connect the surrounding spectrum analyzer, electrical parameter measuring instrument and light-emitting diode to control the power supply to achieve The function of detecting parameters such as chromaticity coordinates, color temperature, color rendering index, color tolerance, wavelength, color purity, luminous flux, vol...
