Light source component, light source system and projection device

Abstract

The invention relates to a light source component, a light source system and a projection device. The light source component comprises an exciting light source, a color wheel and a light filter. The exciting light source is used to generate exciting light; first wavelength conversion material which converts the exciting light to first color light is arranged on the color wheel; and the light filter is provided with a first light filtering area which filters the first color light so as to produce second color light, wherein the difference between the dominant wavelengths of the first color light and the second color light is bigger than or equal to 3nm. According to the invention, through the manner, the first wavelength conversion material capable of converting the exciting light to the first color light cooperates with the light filter to generate the second color light, thus avoiding the use of wavelength conversion material which is relatively high in price or poor in performance and directly absorbs the exciting light to generate second color light. Therefore, the cost of the light source system is reduced and the light conversion efficiency of the light source system is improved.

Description

technical field [0001] The invention relates to the technical field of light sources for illumination and display, in particular to a light source component, a light source system and a projection device. Background technique [0002] At present, many applications require the use of high-brightness color light sources, such as stage lights, projection displays, and RGB backlights. Among them, a gas discharge lamp (for example, an ultra-high pressure mercury lamp) is a traditional high-brightness light source used in special lighting and display fields. However, because mercury is easy to cause environmental pollution, the industry is looking for an environmentally friendly light source to replace the ultra-high pressure mercury lamp. [0003] See figure 1 , figure 1 It is a structural schematic diagram of a light source system in the prior art. Such as figure 1 As shown, the light source system includes a solid state light source 101 , a lens 103 , a color wheel 104 and...

Problems solved by technology

[0004] However, in the existing phosphors, the price of some phosphors is much higher than other phosphors or the working performance is much lower than other phosphors. cost increase

In addition, compared with other phosphors, the red phosphor has a larger Stokes shift loss, which easily leads to an increase in the temperature of the red phosphor, thereby reducing the photoconversion efficiency of the excitation light and the system performance. reliability
