Problems solved by technology
[0002] Based on the rapid development of the automobile industry, people's demand for automobiles gradually tends to be personalized and customized. Automobiles are no longer a black and white choice in the past, and interior parts, as an important part of automobiles, are becoming more and more Personalized design, LED ambient lights for interior parts, panel backlights, odometer lights and other illuminants are more and more used in the development and application of automobiles. How to ensure the consistency of LED light illuminants has become the current A big problem in automobile production, the traditional detection is done by people, or through manual hand-held instrument (colorimeter) detection, the speed is slow, and there is a possibility of missing detection, and it is impossible to achieve accurate color HSL hue (H), saturation (S), and lightness (L) detection, and the luminance value of the European standard (candela / square meter cd / ㎡) cannot be used as the detection standard

Embodiment
[0026] Brightness is the brightness of the light-emitting surface, which refers to the ratio of the luminous intensity of the light-emitting surface in the specified direction to the area of the light-emitting surface perpendicular to the specified direction, and the unit is candela / square meter cd / m^2. Luminous intensity is referred to as luminous intensity, and the international unit is (candela) abbreviated as cd. Lcd refers to the luminous flux emitted by the light source within the unit solid angle of the specified direction. When the radiation of the light source is uniform, the light intensity is I=F / Ω, Ω is the solid angle, the unit is steradian (sr), F is the luminous flux, the unit is lumen, and for a point light source, I=F / 4π.

The invention relates to a luminance value detection system for LED strips of automotive interior parts, which includes a controller, a fixture, a fixture moving mechanism, a displacement sensor, a loading and unloading robot, a detection unit and an output unit. The fixture moves through the fixture The mechanism is connected to the controller, the displacement sensor is arranged in the fixture and connected to the controller, and the loading and unloading robot, detection unit, and output unit are respectively connected to the controller; when the loading and unloading robot puts the detection parts into the tooling After clamping, the displacement sensor transmits the detected component information to the controller, and the controller puts the detected component into the detection unit through control. After the detection unit detects it, it sends the image information of the component to the controller, and the controller will receive After the image information of the image is converted into luminance value information, it is judged whether the component is qualified or not. Compared with the prior art, the invention has the advantages of fast detection speed, no error, easy data preservation, unmanned operation and the like.
