Description
Technical field
The utility model relates to lighting technical field, especially a kind of light fixture.
Background technology
LED(Light Emitting Diode, light emitting diode) there is the advantage such as energy-saving and environmental protection, the every field of be widely used in life, producing.LED outdoor lights waterproof sealing is realized by transparent toughened glass (or transparent plastic), heat radiator body and seal at present, in the light-source chamber of lens in sealing, the light sent from LED is through the absorption of lens and two light transparent member of safety glass (or transparent plastic), the heat that LED produces is the heat loss through radiation successively through two parts at luminous frontal, has reduced the efficiency of head-on radiation heat radiation.How to increase the light extraction efficiency of light fixture, reduce the hot-fluid stroke of lamp luminescence surface to light source simultaneously, increase heat endurance and the reliability of outdoor lamp, and effectively realize the IP(dustproof and waterproof of light source die cavity) sealing, and realize that lens and LED chip are one of current lighting technical field problem demanding prompt solutions in the accurate location of Z direction.
The utility model content
The technical solution of the utility model is for providing a kind of light fixture, comprise: lens (10), radiator (20), light source board (30) and seal (40), said lens (10) forms light-source chamber (A) and annular seal space (B) with described radiator (20), above-mentioned light source board (30) is arranged in the light-source chamber (A) of described lens (10) and described radiator (20) formation, above-mentioned annular seal space (B) is formed by the lens lateral sidewalls (101) of lens (10) and the radiator sealing sidewall (201) of lens vertical side walls (102) and described radiator (20), above-mentioned seal (40) is positioned in described annular seal space (B).
Preferably, lens vertical side walls (102) one sides of said lens (10) are provided with seal groove (103).
Preferably, with described seal groove (103), with described sealing sidewall (201), laminating contacts above-mentioned seal (40).
Preferably, above-mentioned seal (40) contacts with the laminating of described sealing sidewall (201) with described seal groove (103), forms lateral seal.
Preferably, be provided with LED chip on above-mentioned light source board (30).

The specific embodiment
Below in conjunction with the drawings and specific embodiments, a kind of light fixture the utility model proposes is described in further detail.
Fig. 1 is the package assembly schematic diagram of the utility model embodiment mono-, this light fixture mainly comprises a kind of light fixture, comprise: lens (10), radiator (20), light source board (30) and seal (40), said lens (10) forms light-source chamber (A) and annular seal space (B) with above-mentioned radiator (20), above-mentioned light source board (30) is arranged in the light-source chamber (A) of said lens (10) and above-mentioned radiator (20) formation, above-mentioned annular seal space (B) is formed by the lens lateral sidewalls (101) of lens (10) and the radiator sealing sidewall (201) of lens vertical side walls (102) and above-mentioned radiator (20), above-mentioned seal (40) is positioned in above-mentioned annular seal space (B).Wherein, lens 10 and the formed annular seal space B of radiator 20, the intracavity sidewall of annular seal space B adopts the lateral seal scheme, avoid lens 10 in Z-axis direction, seal 40 to be exerted pressure, and then effectively realize and promote the IP(dustproof and waterproof of light fixture) sealing property, and can avoid changing because seal 40 decrements change the positioning precision that causes the LED chip Z-direction on lens 10 and light source board 30.In addition, be provided with LED chip on light source board 30.Z-direction is perpendicular to the plane at LED chip place.
In this programme, seal 40 is a sealing ring,
Fig. 2 is the structure explosive view of the utility model embodiment.
Fig. 3 is radiator and the lens arrangement schematic diagram of the utility model embodiment;
Fig. 4 is the lens arrangement schematic diagram of the utility model embodiment.
Particularly, as Fig. 2, shown in Fig. 3 and Fig. 4, in the utility model embodiment, seal 40 is arranged in the annular seal space B of lens 10 and radiator 20 formation, further, the radiator sidewall 201 of the lens lateral sidewalls 101 of lens 10 and lens vertical side walls 102 and radiator 20 forms an annular seal space B that can hold seal 40, lens vertical side walls 102 1 sides at lens 10 are provided with seal groove 103, above-mentioned seal 40 contacts with seal groove 103 laminatings, seal 40 is in the annular seal space B of lens lateral sidewalls 101 and lens vertical side walls 102 and 201 formation of radiator sidewall, with lens lateral sidewalls 101 and lens vertical side walls 102 and 201 realization laminating and the sealings of radiator sidewall, can effectively avoid lens 10 in Z-direction, seal 40 to be exerted pressure, and then effectively realize and promote the IP(dustproof and waterproof of light fixture) sealing property, and can avoid changing because seal 40 decrements change the positioning precision that causes the LED chip Z-direction on lens 10 and light source board 30.In addition, seal 40 contacts with the laminating of seal groove 103, forms lateral seal.
To the description of the utility model preferred embodiment, be above in order to illustrate and to describe, not want the utility model limit or be confined to disclosed concrete form, obviously, may make many modifications and variations, these modifications and variations may be obvious to those skilled in the art, within should being included in the scope of the present utility model by the appended claims definition.
