The specific embodiment

Embodiment of the present utility model has below been described.

As shown in Figure 1, for the combination schematic diagram of the utility model housing 10 and lens 30, its middle shell 10 is connected by the structure of draw-in groove with lens 30, and circuit board 20 is located between housing 10 and lens 30, LED lamp is located on circuit board 20, and scioptics 30 are outwards luminous.

As shown in Figure 2, be the decomposing schematic representation of the utility model LED light fixture, the circuit board 20 between lens 30 and housing 10 is two, and be electrically connected by the electric connector 201 of being located on circuit board 20, like this, in the time only having a circuit board 20 to damage, the one end that only need open LED light fixture, outwards extract the circuit board 20 damaging out, and change, in providing cost savings, increase the convenience of maintenance, what can know is circuit board more than 20, and the cost in the time changing is just lower.

Preferably, LED light fixture two ends are also provided with end cap 40, and end cap 40 connects in housing 10 by the connected mode of screw, preferred, are also provided with sealing ring, for anti-sealing or dust contact circuit plate 20 between end cap 40 and housing 10.

LED light fixture of the present utility model, comprising: housing 10, and the bottom of this housing 10 is provided with the main latch position 101 of pair of parallel; Lens 30, these lens 30 are provided with a pair of connecting portion 301 corresponding with this main latch position 101 positions, and this connecting portion 301 inserts this main latch position 101; The inner side of this main latch position 101 is also provided with one first jut 1011, and the inner bottom surface of this main latch position 101 is also provided with one second jut 1012; This connecting portion 301 and this first jut 1011, this second jut 1012 connects.Connecting portion 301 is by being connected with the first jut 1011 and the second jut 1012 in main latch position 101, can play dual partition effect, effectively inner circuit board 20 is cut off with extraneous, even the partition that extraneous water and dust consist of connecting portion 301 and the first jut 1011, also the more difficult partition forming by connecting portion 301 and the second jut 1012, greatly reduce the possibility of water and dust contact circuit plate 20, promote the sealing of LED light fixture, such structure also can meet the detachability of lens 30 and housing 10 simultaneously.

As shown in Figure 3, be the schematic cross-section of the utility model LED light fixture the first embodiment, the position of corresponding the first jut 1011 of connecting portion 301 is provided with a groove 3011, and this groove 3011 is pegged graft with this first jut 1011; What this connecting portion 301 was corresponding in the position of the second jut 1012 is provided with an extension 3012, and this extension 3012 overlaps with this second jut 1012.With such connected mode, both can prevent that lens 30 were connected defective tightness with housing 10 and cause water proof and dust proof poor effect, can be too infirm because of connecting yet, cause lens 30 from housing 10 dismounting difficulties.

As shown in Figure 4, be the schematic cross-section of the utility model LED light fixture the second embodiment, in main latch position 101, also comprise draw-in groove 1,013 one time, be located at the side that this main latch position 101 is relative with the first jut 1011; Connecting portion 301 also comprises an extension 3012 corresponding with this draw-in groove 1013, and this extension 3012 inserts this draw-in groove 1013.After adding time draw-in groove 1013, can increase the tightness between lens 30 and housing 10, adopt above structure simultaneously, can prevent that connecting portion 301 is loosening in the interior generation of main latch position 101, and not affecting under dismounting conveniency, make housing 10 be connected more firm with lens 30.

As shown in Figure 3, Figure 4; in the utility model; lens 30 can be narrow optical lens; the light that LED is produced focuses on; or can be wide optical lens; the light that LED is produced is dispersed, and those skilled in the art can know, the scope that the lens arrangement in the case of connecting portion 301 structures that do not have influence on lens 30 is all protected at the utility model.

As shown in Figure 3, Figure 4, the utility model also comprises heat sink 102, and circuit board 20 is close to this heat sink 102, plays the thermolysis to circuit board 20, because circuit board 20 can produce larger caloric value.Preferably, this heat sink 102 is connected with housing 10, and composition one cavity, heat sink 102 can exhale heat by housing 10 like this, and disperse heat by the cross-ventilation of cavity, this heat sink 102 is integrated with this housing 10, can guarantee that like this heat sink 102 effectively goes out a part of dissipation of heat by housing 10, also can be used as the reinforcement of housing 10 simultaneously, play the effect of strengthening housing 10, heat sink 102 can be also to form separately simultaneously, make heat sink 102 more flexible with the combination of circuit board 20, be not subject to the restriction of housing 10.

Should be noted that, embodiment of the present utility model has preferably implementation, and not the utility model is done to any type of restriction, any person skilled in art of being familiar with may utilize the technology contents of above-mentioned announcement to change or be modified to the effective embodiment being equal to, in every case do not depart from the content of technical solutions of the utility model, any modification or equivalent variations and the modification above embodiment done according to technical spirit of the present utility model, all still belong in the scope of technical solutions of the utility model.
