Detailed description of the invention
For the ease of the understanding of those skilled in the art, be further described the utility model below in conjunction with embodiment and accompanying drawing, the content that embodiment is mentioned is not to restriction of the present utility model.See Fig. 1 to Fig. 2, below in conjunction with accompanying drawing, the utility model is described in detail.
The light-source structure of a kind of LED projector lamp provided by the utility model, include reflector 1, this reflector 1 to comprise at the bottom of uncovered cup body 11 and cup 12, and it is shaping that reflector 1 adopts aluminium to carry out spinning process, not only there is the angle effect ensureing luminous bundle, also play a part heat radiation simultaneously.The utility model also includes the heat sink body 2 of hollow type, and this heat sink body 2 adopts the good material of heat conductivility to make; The upper surface of described heat sink body 2 12 to be fixedly connected with at the bottom of cup, heat sink body 2 outside be evenly distributed with multiple LED light source, each LED light source is all towards the internal face of uncovered cup body 11, and the light of LED light source is reflected away by the internal face of uncovered cup body 11.As shown in Figure 1, described LED light source adopts module array structure, around heat sink body 2 even circumferential distribution light source, makes light-emitting area very even.LED light source is when working luminous, the internal face of the uncovered cup body of the direct directive of light, then light is by internal face reflection injection, and the irradiation mode of the LED projector lamp of traditional direct irradiation is changed into reflection outgoing, the shadow surface of its outgoing is relatively more even, and light is soft, not dazzling.
In the utility model, described heat sink body 2 is the polygon heat sink body be made up of polylith fin 21, is provided with the heat radiation gap being convenient to heat loss through convection between two pieces of adjacent fin 21; Between two pieces of fin 21 that heat sink body 2 is adjacent, leave space form convection current, enhance radiating effect.
As preferably, described LED light source is the LED lamp bead 3 of SMT encapsulation, and described LED lamp bead 3 is spaced apart along fin 21 length surface direction.By spaced apart for LED lamp bead 3 length direction in fin 21 surface, this can obtain larger light source luminescent face on the one hand, the installable position of LED lamp bead 3 is wider, is on the other hand to be uniformly distributed the heat that LED lamp bead 3 sends, and makes heat sink body 2 thermally equivalent.Therefore, the heat absorption that heat sink body 2 pairs of LED lamp bead 3 send and release are more even, and the utilization rate of radiator is better.
Further, the lower end of described heat sink body 2 is provided with center lucifuge lid 4, adopts the center lucifuge lid 4 avoiding center dazzle, well solve the center glare problem of light fixture, make light fixture bright dipping softer in centre.Above center lucifuge lid 4, be provided with multiple inserting terminal 5, described center lucifuge lid 4 is removably connected by the lower end of inserting terminal 5 with fin 21, and its installation is simple and quick.
In the utility model, the upper end of described heat sink body 2 is provided with at least three fixed vias 6, and at the bottom of described cup, 12 relatively described fixed vias 6 are provided with connecting through hole 7; Throughly between fixed via 6 and connecting through hole 7 be provided with rivet 8, described heat sink body 2 12 to be fixedly connected with at the bottom of cup by rivet 8.Whole heat sink body 2 carries out riveted with reflector 1 rivet 8, which avoid the loaded down with trivial details technique adopting screw tapping fixing.In addition, rivet 8 is all very simple in the middle of the process of installing and change, and relatively more firm, not easily gets loose.
