Abstract
The utility model relates to a light combination modular based on a light-emitting diode light source system, which mainly comprises a cooling device, a light-emitting diode driving and controlling circuit board, an aligning system, light-emitting diodes, and filter sheets. A red light-emitting diode, a blue light-emitting diode, and a green-emitting diode are separately installed on the cooling device and the light-emitting diode driving and controlling circuit board. Rays emitted by the light-emitting diode enter into the filter sheets via the aligning system, the filter sheets are fixed on a V-type notch of a fixing frame 10, and a shaping and equalizing light cone is set at the light output opening of the light combination modular. Since the external light-emitting diode driving and controlling circuit board can regulate the luminous intensity of the light-emitting diodes, the utility model utilizes the two light filter sheets with a designed angle to realize the aim of light combination, and the light cone for shaping and equalizing the light spot is arranged at the light output opening. The utility model is mainly utilized in projection systems, liquid crystal display projection systems, and other display and illuminating occasions, which can provide a light source with high brightness, good uniformity, abundant colors, low cost, and high flexibility.
Description
Technical field
What the utility model related to a kind of high-brightness LED lighting source closes the photosystem module.
Background technology
Owing to adopt semiconductor LED (light emitting diode) illumination, have advantages such as energy-saving and environmental protection and long-life, therefore main in the world in recent years developed country all drops into very big strength with relevant major company, research institution and develops ultra-high brightness LED, a lot of achievements in research have been obtained, apply for thousands of Patent projects, and constantly enlarged industry size.Because the brightness of LED is more and more higher, not only can replace traditional incandescent lamp as lighting source, in many occasions that need higher source luminance, as the optical projection system light source, the LCD backlight, occasions such as automobile lamp, the application of LED is also more and more widely.Particularly in projection, application scenario such as backlight, the color of LED is very abundant, can access lively especially image, becomes the target that everybody pays close attention to.In order to obtain very high brightness and good chromatogram, need the LED of three kinds of colors of red, green, blue to close photosystem usually and obtain good white light by one.
Traditional photosystem that closes adopts X-Cube to realize mostly, and X-Cube generally is that the prism with several plated films is bonded, and adhesive surface can influence and close light quality.And X-Cube weight is very big, particularly obtains particularly evident than the occasion of large spot at needs.Cost, weight is that X-Cube closes the subject matter that light exists with closing light quality.
And people need regulate the colourity of control light when closing light.Light modulation seems quite important when the function of a plurality of types that satisfy the space and aesthstic needs.People more and more pay attention to the purposes of White LED now, thereby make that light controller continues to bring out more flexibly.Yet, be still a major challenge in the conforming LED system that regulates simultaneously that keeps white light, generally speaking, the transformation of light modulation colourity realizes still unsatisfactory.
Summary of the invention
The purpose of this utility model is for the cost, the weight that overcome X-Cube and close problem such as light quality, improves the flexibility of closing photosystem, and a kind of converging module is provided.This converging module utilizes colour filter to replace the huge X-Cube prism of volume weight, can access higher closing optical efficiency and close light quality, and the trichromatic luminous intensity of the reasonable control of energy has good dimming capability simultaneously.
Technical solutions of the utility model are: a kind of converging module based on the led light source system, mainly comprise heat abstractor, LED driving and control circuit board, colimated light system, LED, colour filter, respectively with red, blue, green three kinds of LEDs (3,4,5) be installed in respectively on heat abstractor 1 and LED driving and the control circuit board 2, each LED enters colour filter through lineal surely system 6, colour filter (7,8) be fixed on the V-shaped groove of fixed frame 10, shaping homogenizing light cone 9 be set at the light delivery outlet of converging module.The angle of V-shaped groove is the 60-100 degree.
Anti-green blue colour filter 7, instead be popular in bluish-green colour filter 8 and be separately fixed on the V-shaped groove of fixed frame 10, and corresponding with the light source of the light source of green LED, Red LED1 LED respectively.Colimated light system 6 usefulness light cones or set of lenses collimate, and light cone comprises hollow cone and solid light-cone.
The utility model utilizes two frivolous anti-traditional X-Cube prisms of bluish-green and anti-green blue colour filter replacement that are popular in.Two colour filters are bonded at the both sides of the V-shaped groove that designs angle, and the light that the LED of three kinds of colors sends finally is incorporated into together through colour filter control light path.Light-emitting window is placed a cone prism, and the size and the shape of control output facula play the effect of homogenizing hot spot simultaneously.In addition, the LED of three kinds of colors controls by drive circuit, conveniently regulates the luminous intensity of three kinds of color LED, reaches the purpose of light modulation.
The utility model colour filter is cheaply realized closing photosystem, can reach very high closing optical efficiency and close light quality.Can control easily simultaneously and close light spectrum and intensity, light modulation is easy.It is low that whole module has a cost, the light compactness of structure, efficient height, flexibility advantages of higher.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the LED colimated light system figure that realizes with light cone.
Fig. 3 is the LED colimated light system figure that realizes with set of lenses.
Wherein among the figure: the 1-LED heat abstractor; 2-LED drives and control circuit board; The 3-red LED lamp; The 4-green LED lamp; 5-blue led lamp; The 6-colimated light system; The anti-green blue colour filter of 7-; 8-is counter to be popular in bluish-green colour filter; 9-shaping homogenizing light cone; The 10-fixed frame
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
In Fig. 1, LED (3,4,5) is combined on heat abstractor 1 and LED driving and the control circuit board 2, and LED is by the power and the colourity of LED driving and control circuit board 2 regulation and control output beams, and process colimated light system 6 reduces its angle of divergence.Two colour filters, anti-green blue colour filter 7 and instead be popular in bluish-green colour filter 8 and be fixed on the V-shaped groove of fixed frame 10, the angle of V-shaped groove is 80 to spend.What anti-green blue colour filter 7 was installed above is green LED light emitting source, and counter what be popular in that bluish-green colour filter 8 installs below is red LED light emitting source.The light of three kinds of colors lumps together the formation white light behind the color chips after filtration, and output beam obtains the hot spot of needs through shaping homogenizing light cone 9.
In embodiment illustrated in fig. 2, the collimation that expression colimated light system 6 utilizes light cone to realize.Light cone comprises hollow cone and solid light-cone, and LED stretches into light cone inside, reduces optical energy loss, improves and closes optical efficiency.
