Description
Technical field
The illuminator that the present invention relates to a kind of lens module for light source and have this lens module.
Background technology
The illumination of lighting device is used more and more extensively in the modern society, and the lighting requirement of illumination apparatus is also more and more higher, and for example different users is different for the requirement of illumination.For example for the elderly user, reading when them or work in, wish that the brightness of light can be higher.Therefore, provide the lens module of little light beam output angle to receive welcome.Yet for the young man, may not need so little light beam output angle.Therefore, in the urgent need to proposing a kind of lens module that can adapt to the lighting requirement of different user.
Thereby propose in the prior art that lens module is injection molded into an integral body and obtain needed light distribution.But the shortcoming of this technology is: because different applicable cases needs different lamps, therefore, and in order to win more clients, need to be more in the mould cost.And the user also has to be concerned about the selection of different lens modules, and this all is disadvantageous for manufacturer and user.
Summary of the invention
The object of the present invention is to provide a kind of new lens module, this lens module can overcome each shortcoming that exists in the prior art, can provide multiple different light to distribute and multiple do not share the same light distribute between easy switching.
Purpose according to the present invention realizes like this: a kind of lens module for light source, it is characterized in that, comprise collimator lens unit and fly's-eye lens unit, described collimator lens unit has at least one collimation lens, described fly's-eye lens unit has the first fly's-eye lens and the second fly's-eye lens at least, described fly's-eye lens unit can be adjusted between primary importance and the second place with respect to collimator lens unit, in primary importance, described the first fly's-eye lens is aimed at output the first emergent light with described collimation lens, in the second place, described the second fly's-eye lens is aimed at output the second emergent light with described collimation lens.Owing to added adjustable fly's-eye lens unit, therefore different positions can be adjusted in the fly's-eye lens unit, when primary importance, described the first fly's-eye lens is aimed at described collimation lens, the first fly's-eye lens is designed to so that collimated light provides the first emergent light through these lens the time, when the second place, described the second fly's-eye lens is aimed at described collimation lens, and the second fly's-eye lens is designed to so that collimated light provides the second emergent light through these lens the time.The first emergent light and the second emergent light can aspect the beam angle and other side different.Preferably, the fly's-eye lens unit can upwards be adjusted between primary importance and the second place in week with respect to collimator lens unit.
Preferably, described collimator lens unit comprises with predetermined angle intervals at the equally distributed a plurality of collimation lens that makes progress in week.Can the light from all directions be collimated by different collimation lenses simultaneously, and because collimation lens is equally distributed, therefore, the light beam that collimates is uniform.
Preferably, described fly's-eye lens unit comprise bearing and be arranged on the described bearing with described predetermined angle intervals make progress in week equally distributed a plurality of the first fly's-eye lens and with described predetermined angle intervals at equally distributed a plurality of the second fly's-eye lens that makes progress in week.Owing to be provided with identical predetermined angular intervals, therefore, can so that collimation lens and the first fly's-eye lens or the second fly's-eye lens aim at one by one.In addition, because the first fly's-eye lens and the second fly's-eye lens are distributed in week upwards, therefore, and when being transformed into the position of the second fly's-eye lens aligning collimation lens in the position of aiming at collimation lens from the first fly's-eye lens, more convenient manipulation.
Preferably, described the first fly's-eye lens and described the second fly's-eye lens are alternately distributed.Like this, can be so that the user when adjusting the fly's-eye lens unit with respect to the position, angle of collimator lens unit, needs the smaller switching that just can be implemented between the first fly's-eye lens and described the second fly's-eye lens of angle of adjusting.
Preferably, the quantity of described the first fly's-eye lens and the second fly's-eye lens is three.Also can be other quantity, the quantity of the first fly's-eye lens and the second fly's-eye lens be three can be so that can realize converging preferably from the light beam of three fly's-eye lenses output respectively.
Preferably, described the first fly's-eye lens is designed to provide described first emergent light of the first beam angle with 10 °.Thereby the emergent light that brightness is higher, range of exposures is less light is provided, thereby has satisfied the elderly's reading demands.
Preferably, described the second fly's-eye lens is designed to provide described second emergent light of the second beam angle with 30 °.Thereby provide brightness emergent light lower, that range of exposures is larger, thereby satisfied young man's reading demands.
Preferably, described collimation lens produces collimated light beam.Thereby be convenient to realize different emergent lights by the fly's-eye lens unit.
Preferably, described collimation lens have the described substrate of annular and from the described substrate extended frame, be used for holding described bearing, thereby realize the lens module that compact is installed.
Preferably, described substrate have central protuberance and described bearing have for the pilot hole of the corresponding setting of described central protuberance.Thereby be convenient to realize the installation of collimator lens unit and fly's-eye lens unit.
The invention still further relates to a kind of illuminator with said lens module.
Can provide according to the present invention a kind of can provide multiple different light to distribute and multiple do not share the same light distribute between the lens module of easy switching.
