Detailed description of the invention
By reference to the accompanying drawings the present invention is described in further detail below by specific embodiment.
Consider that in LED spotlight, structure is single, the problem of function singleness, the invention provides a kind of LED spotlight.
A kind of LED spotlight, comprising: heat radiation body, LED light source module, reflector, optical function annex, wherein, heat radiation body comprises: housing, installation panel, installation panel is arranged at the lower end in housing, is fixed on the medial surface of housing, and perpendicular to the axis of housing; The medial surface hoop of housing has installing ring and lower installing ring; Upper installing ring is parallel up and down with lower installing ring, is all in the below of installation panel; LED light source module is installed on the lower surface of installation panel; The cup body of reflector snaps in installing ring; The upper end of optical function annex snaps in lower installing ring.
This LED spotlight comprises heat radiation body, LED light source module, reflector, optical function annex.Wherein, LED light source module is arranged in heat radiation body, and reflector is also arranged in heat radiation body, is in the below of LED light source module; Optical function annex is arranged on the below of reflector, for presenting various optical effect.This LED spotlight presents to optical effect the change relying on optical function annex, although optical function annex can adjust as required, but optical function annex is all snap onto on the lower installing ring of heat radiation body.Therefore, the variation of optical function annex, and the connected mode of optical function annex and heat radiation body is simple, LED spotlight overall structure is simple.
Next, this structure is described in detail by some embodiments simple, the LED spotlight that optical effect is various:
Embodiment 1:
This LED spotlight, as shown in Figure 1, it comprises: heat radiation body 1, LED light source module 5, reflector 7, optical function annex.Heat radiation body 1 is the agent structure of shot-light, the supporting role of collecting and distributing heat and other optical modules.Optical function annex can provide various optical effect.
Above-mentioned heat radiation body 1 comprises: housing, installation panel 2.Installation panel 2 is arranged at the lower end in housing, be fixed on the medial surface of housing, namely installation panel 2 is in housing, and is fixedly connected with the inner surface of housing, and this being fixedly connected with directly can contact fixing welded with the inner surface of housing for the side of installation panel 2; Or directly one processing; Or by connector, the two is fixedly connected with together.LED light source module 5 is installed on the lower surface of installation panel 2; What send in order to avoid the LED light source module 5 be arranged on installation panel 2 is stopped by shell inner surface, and installation panel 2 is perpendicular to the axis of housing, and the light that LED light source module 5 sends can directly penetrate in housing.The medial surface hoop of housing opens installing ring 3 and lower installing ring 4; Upper installing ring 3 is parallel with lower installing ring about 4, is all in the below of installation panel 2; Be arranged in parallel and just can be more conducive to light injection, reduce the light loss of the light in shot-light injection.The cup body of reflector 7 snaps in installing ring 3; The upper end of optical function annex snaps in lower installing ring 4.
In order to be arranged on heat radiation body 1 by stable for LED light source module 5, in the scheme of above-mentioned Basic Design, further increase LED light source module fixture 6.Use for cooperated with LED light source module 5.LED light source module fixture 6 is laminated structure, and centre has through hole, and this through hole passes for the LED light source of LED light source module 5.In the housing of heat radiation body 1, LED light source module fixture 6 is parallel with installation panel 2, and bolt connects.Fitted bolt, installation panel 2 and LED light source module 5 all arrange screwed hole in the two corresponding position, and the two relative position screwed hole UNICOM, passes for bolt.It should be noted that, in order to improve symmetry, the counterbalance effect of attachment force, the number of bolt is multiple, and is uniformly distributed on installation panel 2, or is circumferentially uniformly distributed same.In any case design distribution mode, the principle of design should defer to equilibrium and the Stability Analysis of Structures of power.
Because LED light source module 5 comprises LED light source and substrate, LED light source is arranged on substrate.Therefore, in order to be fixed in heat radiation body 1 by stable for LED light source module 5, do the size of through hole and further design, hole size is less than the size of the substrate of LED light source module 5, and to facilitate LED light source to pass through hole, substrate cannot pass.Pass with through hole edge barrier substrate, then can prevent LED light source module 5 from dropping from heat radiation body 1.
