The specific embodiment
Below in conjunction with accompanying drawing the utility model is made concrete further instruction.A kind of novel multiple beam angle Light Distribution Led Light, it comprises by bonnet 1, Lamp cup 4, encircle 41 in the lamp body, ring 42 in the lamp body, the tubular lamp body that lamp body outer shroud 61 consists of, 1 of Lamp cup 4 and bonnet are connected by radiator 2, described radiator is equipped with light source board 32 times, it is characterized in that: annular array distribution has some LED lamp pearls 7 on same circumference on the described light source board 3, described lamp body outer shroud 61 is provided with rotatable adjusting cover 6, regulate in the cover 6 lens 5 is installed, same circumference of corresponding LED lamp pearl 7 arrays is provided with the lens of some groups of different focal on it, and rotary face covers 6 can make that the same group of lens with the same focal length overlap with LED lamp pearl 7 on the lens 5.
Better, the focal length of lens on the described lens 4 is preferably three kinds, be respectively wide-angle lens 83, middle angle lens 82, narrow angle lens 81, above-mentioned each lens successively the equidistant ring array distribution on the same circumference of LED lamp pearl array, certainly focal length of lens kind also can be set to 4 kinds, 5 kinds, 6 kinds even more, in the utility model, light fixture as plaintext, preferably be provided with wide, in, narrow three kinds, to satisfy the instructions for use of most people, the client also can use the actual demand setting according to it, only need to change the focal length of a lens, with add focal length of lens kind and get final product, so advantage such as it is changeable to have the light fixture angle, unrestricted.
In described wide-angle lens 83, middle angle lens 82, the narrow angle lens 81, angle is 20 degree annular arrays distributions between adjacent two lens.
Described adjusting cover 6 can be provided with rotation with respect to lamp body outer shroud 61, and several select gear, gear of every rotation, the lens that namely drive one group of the same focal length overlap with LED lamp pearl, lens are with after LED lamp pearl overlaps, the light that LED lamp pearl sends can be focused on by lens reflection, utilize different focal lens on light line focus effect different, satisfy the demand to different beam angles.
Described selection numbers of gear steps equates with focal length of lens kind quantity, is preferably 3 grades, and the anglec of rotation is 20 degree between every gear.
Preferably, described LED lamp pearl is preferably 6 annular arrays and is distributed on the same circumference, is provided with a light filling LED lamp pearl 71 in the center of this circumference, forms seven-star battle array shape.If in some large-scale light fixtures, can adopt the multi-level annular array of LED lamp pearl of greater number to distribute, cooperate the lens combination corresponding with its quantity, can satisfy the more requirement of high brightness and Geng Duo gear beam angle variation.
Preferably, described adjusting cover 6 is provided with lighting angle mark 62, and described lamp body outer shroud 61 is provided with token-based on schedule, identifies for the convenience of the user the lens of various focal lengths, can engrave corresponding numerical value at the lamp body outer shroud.
Preferably, described lens distribution sequence is followed successively by wide-angle lens 83, middle angle lens 82, narrow angle lens 81, said sequence is just in order to make things convenient for the user to regulate use, focal length can be installed from big to small during actual the use, or from small to large arranged sequentially, not in order also can, tool actual conditions and deciding.
Operation principle: the front end at the tubular lamp body in the utility model is provided with and can rotates adjusting cover 6 relative to lamp body outer shroud 61, regulate in the cover 6 lens 5 is installed, same circumference of corresponding LED lamp pearl 7 arrays is provided with the lens of some groups of different focal on it, because lens and lamp pearl are positioned on the same circumference in the same center of circle, so cover 6 is regulated in rotation in any case, the movement locus of lens drops on the circumference of LED lamp pearl 7 all the time, so lens overlap with the lamp pearl on the lens 5 as long as the rotational angle that cover 6 is regulated in the each rotation of control can make, moreover, the lens of some different focal are successively on the equidistant array distribution lens 5, for the user easy to adjust, can be provided with some gears at adjusting cover 6, do not rotate a gear, every rotation Primary regulation cover just fixedly rotates a certain angle, so that can make one group of lens with the same focal length overlap with each LED lamp pearl 7.After lens and lamp pearl were overlapping, the light that the lamp pearl sends can be focused on by lens reflection, formed the light beam of corresponding angle, regulates cover 6 such as rotation wide-angle lens 83 is overlapped with the lamp pearl, and then light fixture sends wide-angle light beam.As rotate and regulate cover 6 the narrow angle lens 81 on 5 are overlapped with the lamp pearl, then light fixture sends the narrower light beam of angle.Therefore between the lens of different focal, switch, just can change LED through the light angle of lens, not only can control preferably the angle of bright dipping, and so that also can change thereupon regulating size at the spot size that shines preset distance, in the size of regulating hot spot, its brightness also changes thereupon in addition, hot spot is less, brightness is higher, and hot spot is larger, and brightness is lower.The focusing mode that is different from distance between traditional adjusting lens and the LED, the utility model is by integral lens and switches as required the purpose that the lens mode reaches the change beam angle, this device technique scheme directly grafting arrives above current all light fixtures, profile also can have multiple variation (shown in Fig. 5,6,7), satisfy the instructions for use of different occasions, has the scope of application wider, and light modulation is convenient, the advantages such as technology maturation is stable, therefore can be mass-produced, extensively promote the use of, satisfy the demand that user's multiple angles is selected.
Obviously, above-described embodiment only is for example clearly is described, and is not the restriction to embodiment.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here need not also can't give all embodiments exhaustive.And the apparent variation of being extended out thus or change still are within the protection domain of claims that the utility model creates.
