Introduction
What are the test items for Linear Led Strips Diffuser quality inspection report? Linear Led Strips Diffuser are loved by consumers because of their good quality and low price and strong practicability. Now it is mainly used in indoor space, entertainment places, stage lighting, video screen, landscape lighting, etc. However, generally, quality inspection reports are required for such products to be sold on e-commerce platforms. What are the test items in the quality inspection report? Now let’s have a look.
What are the uses of quality inspection reports for Linear Led Strips Diffuser

Linear Led Strips Diffuser detection technology:
Luminous intensity The intensity of light is the amount of light emitted at a specific angle. Because the light of LED is concentrated, the inverse square law is not applicable in the case of short distance. CIE127 standard stipulates that two conditions for measuring the average normal light intensity are proposed for the measurement of light intensity: measurement condition A (far-field condition) and measurement condition B (near-field condition). The area product of the detector under both conditions is 1cm2. In general, the luminous intensity is measured using standard condition B.
The luminous flux and luminous efficiency detection luminous flux are the sum of the luminous amount emitted by the light source, namely the luminous amount.
Spectroscopy. Passing spectral energy P（ λ） The luminous flux is calculated from the distribution. Use a monochromator to measure the 380nm~780nm spectrum of the standard lamp in the integrating sphere, and then measure the spectrum of the lamp to be tested under the same conditions, and calculate the luminous flux of the lamp to be tested by comparison.
The luminous efficiency is the ratio of luminous flux emitted by the light source to the power consumed. Usually, the luminous efficiency of LED is measured by constant current method.Spectral characteristic detection The spectral characteristic detection of LED includes spectral power distribution, color coordinates, color temperature, color rendering index, etc.
Color temperature refers to the amount of light source color table (appearance color representation) seen by human eyes. When the light emitted by the light source is the same color as the light emitted by the absolute black body at a certain temperature, the temperature is the color temperature. In the field of illumination, color temperature is an important parameter to describe the optical characteristics of light source. The theory of color temperature is derived from the black body radiation, which can be obtained from the color coordinates containing the black body trajectory through the color coordinates of the light source.
