Description
Technical field
The present invention relates to a kind of lighting device.
Background technology
The LED luminescence component has higher efficient, the life-span of growing and lower power consumption, and more and more welcomed by the people.There is a large amount of LED remodeling lamps in current market.In some special applications, require LED remodeling lamp rearward to shine, produced thus the LED lighting device of penetrating function after having.Such LED lighting device has heat abstractor usually, is placed in led light source in the heat abstractor and the led driver of driving LED light source.Penetrate function for after realizing, offer the slit between the adjacent fin of heat abstractor, the light of led light source can pass through this slit to the side and the rear is penetrated.In addition, also need be provided with lens at the light-emitting window place of radiator, these lens can be processed the light of led light source, to satisfy different illuminating effects.Penetrate after having in the LED lighting device of function, these lens can also reflect a part of light, thereby can rearward shine by the slit of fin.But in order to fix this lens, usually use in the prior art additional keeper, this keeper covers on the lens, and utilizes bolt keeper to be fixed on the light-emitting window place of heat abstractor together with lens.But this structure has increased the difficulty of assembling, simultaneously because these annexes have caused the raising of cost.
Summary of the invention
For solving the problems of the technologies described above, the present invention proposes a kind of lighting device, the lens of this lighting device need not on the heat abstractor that any annex can remain on lighting device, and its assembling is simpler, and has less cost.
Purpose of the present invention realizes thus by a kind of lighting device, and namely this lighting device comprises heat abstractor, and described heat abstractor comprises matrix, forms in matrix at least at the open container cavity of a side, and the open end of container cavity is designed to the first light-emitting window; Luminescence component is arranged in the container cavity, wherein, lighting device also comprises lens, and these lens comprise the first connecting portion, and heat abstractor comprises the second connecting portion, wherein, lens extend at least in part in the container cavity and utilize the first connecting portion and be connected connecting portion and be connected with heat abstractor.Can need not any cover plate and bolt can be fixed on the heat abstractor of lighting device according to the lens of lighting device of the present invention, this has reduced on the whole according to the assembly difficulty of lighting device of the present invention and installation time.
Preferably, lens have roof and from the edge-perpendicular of roof the annular sidewall that extends out.By annular sidewall is extend in the container cavity of heat abstractor, can simply lens be fixed on the heat abstractor, be the securing members such as the necessary cover plate of mounted lens institute and bolt thereby cancelled.
A preferred design according to the present invention proposes, the first connecting portion is designed to be formed on the free terminal of annular sidewall and the grab that extends radially outwardly, this grab is snapped into and is designed in draw-in groove the second connecting portion, and wherein draw-in groove is formed in the inwall of the matrix that limits container cavity.This buckle connects the connectivity robustness of having guaranteed lens and heat abstractor, and the assembling of simultaneously buckle connection is very easy to, and this has improved the production efficiency of lighting device.
Preferably, lens have the cross section with the cross section of the first light-emitting window coupling, and wherein, at least part of annular sidewall forms the first connecting portion, and at least a portion of inwall that limits the matrix of container cavity forms the second connecting portion.Thus, after being installed to lens on the heat abstractor, only can have very small gap between the first light-emitting window and lens, it is more attractive in appearance that this is not only lighting device, also improved the sealing effectiveness of lighting device simultaneously.
Another preferred design according to the present invention proposes, and the first connecting portion and the second connecting portion are abutted together in the mode of interference fit.Usually has certain pliability owing to making the material of lens, therefore, must be than the size of the cross section of the first light-emitting window of container cavity slightly more greatly with the size design of the cross section of lens, when being inserted into the sidewall of lens in the container cavity so, sidewall will only be resisted against on the inside of container cavity, thereby lens are fixed on the heat abstractor in the mode of interference fit.
According to another preferred design of the present invention, be formed with screw thread at the first connecting portion, this is threaded in the corresponding screw thread that forms on the second connecting portion.Can simply lens be fixed on the heat abstractor by relay lens.
According to a preferred design of the present invention, the first connecting portion of lens also can be bonded on the second connecting portion of lens by bonding agent.Simply lens are fixed on the heat abstractor in this way, have also guaranteed the sealing of lighting device simultaneously.
Preferably, heat abstractor also is included in a plurality of fin that extend radially outwardly on the outer surface of matrix.By the outer surface at matrix the contact area that fin can increase heat abstractor and surrounding environment significantly is set, this has improved the heat dispersion of heat abstractor significantly.
Preferably, offer the second light-emitting window between the adjacent fin, this second light-emitting window is passed in the container cavity.In addition, the sidewall of lens is made by transparent material.Thus, come the light of luminescent module from the second light-emitting window, to penetrate by sidewall, thereby make lighting device realize backward illumination to a certain degree.
Advantageously, luminescence component is designed to the LED luminescence component.The LED luminescence component has advantages of that the life-span is long, luminous efficiency is high and more environmental protection.
