A special white light source for ceramic lampshade and its manufacturing method

Abstract

The invention discloses a setting method of a white light source special for a ceramic lampshade. The setting method comprises the following steps: the light absorption characteristic of the ceramic lampshade is firstly measured, and when the ceramic lampshade absorbs certain wavelength section, the light intensity of the certain wavelength section of the white light source with the COB blue light integrated optical source structure is strengthened through fluorescent powder ratio to obtain the white light source special for the ceramic lampshade; the light transmittance performance of the ceramic lampshade is related to the ceramic raw material for manufacturing the ceramic lampshade, the sintering process and the thickness of the ceramic lampshade, and the optical absorption characteristics of different ceramic lampshades are different, that is the wavelengths and strengths of light rays absorbed by different ceramic lampshades are different; an LED white light source after being powered on emits the white light of spectrum matched with the ceramic, the white light ray of the spectrum irradiates the ceramic lampshade, the light ray emitted by the LED white light source is transmitted by the ceramic lampshade to form emergent light, and the emergent light meets a standard color coordinate and meets the visual requirements of human eyes to common white light; the white light source is an LED white light source special for the ceramic lampshade.

Description

technical field [0001] The invention relates to the field of lighting technology, in particular to a special LED white light source for ceramic lamp shades and a manufacturing method. Background technique [0002] Ceramic lamps are mostly composed of ceramic lampshades, light sources and other auxiliary components such as lamp holders. At present, there are many types of ceramic lampshades on the market, including ceramics made of various ceramic raw materials and sintering processes, such as ceramics containing alumina components, ceramics containing zirconia components, and ceramics containing magnesia components. The light sources commonly used in ceramic lampshades include ordinary tungsten filament bulbs, energy-saving lamps (including daylight color and warm white, etc.) and LED bulbs. [0003] Ceramics are inorganic materials that are generally opaque and absorb light. If the components of the ceramics are specially designed, the thickness of the ceramic body is red...
