Description

Illuminator
Technical field
The present invention relates to a kind of illuminator.
Background technology
LED luminescence components have higher efficiency, longer life-span and relatively low power consumption, and increasingly by the joyous of people Meet.There is substantial amounts of LED modification lamp on current market.In some special applications, it is desirable to which LED modification lamp can Rearward irradiate, thereby produce the LED light device that function is penetrated after having.Such LED light device generally has Heat abstractor, the LED light source being placed in heat abstractor and the LED driver for driving LED light source.In order to penetrate work(after realizing Can, offer gap between the adjacent fin of heat abstractor, the light of LED light source can by the gap to side and Project at rear.Additionally, at the light-emitting window of radiator also needing to be provided with lens, the lens can be carried out to the light of LED light source Process, to meet different illuminating effects.Penetrate after having in the LED light device of function, the lens can also reflect one Light splitter, so as to can rearward be irradiated by the gap of fin.But in order to fix the lens, in the prior art Additional keeper is usually used, the keeper is covered on lens, and keeper is fixed on into radiating together with lens using bolt At the light-emitting window of device.But the difficulty of assembling is such a structure increases, simultaneously as these adnexaes, result in carrying for cost It is high.
The content of the invention
To solve above-mentioned technical problem, the present invention proposes a kind of illuminator, and the lens of the illuminator are without the need for any Adnexa is positively retained on the heat abstractor of illuminator, and its assembling is relatively simple, and has less cost.
The purpose of the present invention is achieved in by a kind of illuminator, i.e., the illuminator includes heat abstractor, described to dissipate Thermal includes matrix, forms the accommodating chamber at least opening in side in the base, and the open end of accommodating chamber is designed as first and goes out Optical port;Luminescence component, is arranged in accommodating chamber, wherein, illuminator also includes lens, and the lens include first connecting portion, dissipate Thermal includes second connecting portion, wherein, during lens extend at least partially into accommodating chamber and using first connecting portion and second Connecting portion is connected with heat abstractor.The lens of illuminator of the invention be able to can be fixed on without the need for any cover plate and bolt On the heat abstractor of illuminator, when this reduces the assembly difficulty of illuminator of the invention and assembling on the whole Between.
Preferably, the annular sidewall that lens extend out with having roof and the edge-perpendicular from roof.By making ring Shape side wall is extend in the accommodating chamber of heat abstractor, and simply lens can be fixed on heat abstractor, so as to eliminate as peace Dress lens institute must the securing member such as cover plate and bolt.
One of the invention preferred design proposes, first connecting portion be designed as being formed in annular sidewall from By end and the grab that extends radially outwardly, the grab is snapped into and is designed as in draw-in groove second connecting portion, and wherein draw-in groove is formed in In the inwall of the matrix for limiting accommodating chamber.It is this to snap connection the connectivity robustness that ensure that lens and heat abstractor, while card The assembling of button connection is very easy to, and this improves the production efficiency of illuminator.
Preferably, lens are with the cross section matched with the cross section of the first light-emitting window, wherein, at least part of annular Side wall is formed as first connecting portion, and limits at least a portion of the inwall of the matrix of accommodating chamber and be formed as second connecting portion. Thus, after lens are installed on heat abstractor, can only there is very little gap between the first light-emitting window and lens, this It is not only that illuminator is more attractive in appearance, while also improving the sealing effectiveness of illuminator.
Another preferred design of the invention proposes that first connecting portion and second connecting portion are with interference fit Mode be abutted together.As the material for making lens generally has certain pliability, therefore, by the cross section of lens The size for being sized to the cross section of the first light-emitting window than accommodating chamber is slightly larger, then be inserted into the side wall of lens When in accommodating chamber, side wall only will be resisted against on the inside of accommodating chamber, so that lens are fixed in an interference fit On heat abstractor.
Another preferred design of the invention, is formed with screw thread in first connecting portion, and this is threaded into Formed in the corresponding screw thread in second connecting portion.Simply lens can be fixed on heat abstractor by relay lens.
One of the invention preferred design, the first connecting portion of lens can also be bonded in by bonding agent In the second connecting portion of lens.Simply lens are fixed on heat abstractor in this way, while also ensure that illumination The sealing of device.
Preferably, heat abstractor is additionally included in the multiple fin extended radially outwardly on the outer surface of matrix.Pass through The contact area that fin can significantly increase heat abstractor and surrounding is set on the outer surface of matrix, and this is significantly Improve the heat dispersion of heat abstractor.
Preferably, the second light-emitting window is offered between adjacent fin, second light-emitting window is passed in accommodating chamber. Additionally, the side wall of lens is made of clear material.Thus, the light for carrying out luminescent module can be by side wall from the second light-emitting window Project, so that illuminator realizes a certain degree of backward illumination.
Advantageously, luminescence component is designed as LED luminescence components.LED luminescence components have life-span length, luminous efficiency high with And the more advantage of environmental protection.
