Description
Technical field
The present invention relates to a kind of combined optical module and projection arrangement, particularly relate to and a kind ofly more can save the space, and have than macrostructure intensity, can increase the combined optical module application, can add the homogenising and the centralization of strong beam, other can be applied in combined optical module in the projection, and can improve the combined optical module with prism and the projection arrangement of usefulness and application.
Background technology
Since nineteen sixty begins commercialization for light emitting diode because have high vibration strength, the life-span is long, volume is little, so its range of application spreads all over the every articles for use in the daily life gradually, for example in lighting device and display device as light emitting source or backlight.In display device, light emitting diode is still needed and other optical elements are arranged in pairs or groups to produce full-color visual effect, and one of them important optical element is optical filter (dichroic filter).Optical filter is to plate multiple spectro-film (dichroic film) by a glass plate, when light after filtration during mating plate, the light of part wavelength period can be filtered, and the light of another part wavelength period is passed.Because optical filter has the optical characteristics of selective light wavelength, so optical filter also is used in many optical application, wherein a kind of application is for closing light.
Seeing also shown in Figure 1ly, is an a kind of synoptic diagram of existing known combined optical module, and this existing known combined optical module 1 comprises one first optical filter 11, one second optical filter 12, a red diodes 13, a blue light diode 14 and a green diode 15.Wherein, be coated with a ruddiness spectro-film on first optical filter 11, be coated with a blue light spectro-film on second optical filter 12, red diodes 13 is sides that are adjacent to first optical filter 11, and launch a red light beam, blue light diode 14 is sides that are adjacent to second optical filter 12, and launches a blue light light beam, green diode 15 is the opposite sides that are adjacent to first optical filter 11, and launches a green beam.
Owing to be coated with a ruddiness spectro-film on first optical filter 11, so red light beam can and penetrate second optical filter 12 and arrives one and close light zone 16 via 11 reflections of first optical filter; In addition, owing to be coated with a blue light spectro-film on second optical filter 12,, the blue light light beam closes light zone 16 so can arriving via 12 reflections of second optical filter; In addition, green beam is to penetrate first optical filter 11 and second optical filter 12 and arrive and close light zone 16.So combined optical module 1 can reach two purposes, the firstth, the light beam from different directions is directed to the same area, the secondth, with the synthetic another kind of light beam of different light beams.Because ruddiness, blue light and green glow are the three primary colors of light, so in closing light zone 16, the scope that three light beams occur simultaneously can form a white light beam.
Though combined optical module 1 can reach the effect of closing light, because its two optical filter is that branch is arranged, so its needed space is bigger, and the intensity of its structure is also less; In addition, the closing the light zone and can only be fixed on same direction of combined optical module 1, the selectivity of application is lower.In addition, it does not disclose how to be applied to other optical devices (as projection arrangement), makes combined optical module 1 except closing light, can't bring into play other function.
This shows that above-mentioned existing combined optical module and projection arrangement obviously still have inconvenience and defective, and demand urgently further being improved in structure and use.In order to solve above-mentioned existing problems, relevant manufacturer there's no one who doesn't or isn't seeks solution painstakingly, but do not see always that for a long time suitable design finished by development, and common product does not have appropriate structure to address the above problem, this obviously is the problem that the anxious desire of relevant dealer solves.Therefore how to found a kind of combined optical module and projection arrangement of new structure, solve the problems referred to above, to improve usefulness and application, belong to one of current important research and development problem in fact, also becoming the current industry utmost point needs improved target.
Because the defective that above-mentioned existing combined optical module and projection arrangement exist, the inventor is based on being engaged in this type of product design manufacturing abundant for many years practical experience and professional knowledge thereof, and the utilization of cooperation scientific principle, actively studied innovation, in the hope of combined optical module and the projection arrangement of founding a kind of new structure, can improve general existing combined optical module and projection arrangement, make it have more practicality.Through constantly research, design, and, create the present invention who has practical value finally through after studying sample and improvement repeatedly.
