The specific embodiment
Below in conjunction with accompanying drawing and the specific embodiment, the utility model is described in further detail.
The big-angle LED lamp 100 of the utility model the first embodiment, please refer to Fig. 1 to Fig. 3.
Please refer to Fig. 1, Fig. 2 and Fig. 3, this big-angle LED lamp 100 mainly comprises lampshade 10, light source board 20 and lamp body 30.This light source board 20 is arranged on the top of this lamp body 30, and this light source board 20 is provided with a plurality of LED light sources 21, and this light source board 20 forms and is electrically connected to (not shown) with driving element.These lampshade 10 bottom openings, this lampshade 10 is located at the top of this lamp body 30.
Please refer to Fig. 1 and Fig. 3, this lamp body 30 comprises body 31 and radiating piece 32, this radiating piece 32 is set in the periphery of this body 31, this body 31 is provided with upwardly extending buckling parts 311, this buckling parts 311 is compressed to this light source board 20 end face of this radiating piece 32, makes this light source board 20 and this radiating piece 32 form thermally coupled.
Please refer to Fig. 1 and Fig. 3, these lampshade 10 bottom opening places are provided with to the fastening structure of downward-extension and the buckling parts 311 of this lamp body 30 and coordinate, and this lampshade 10 can be facilitated and the firm top that is located at this lamp body 30.
Please refer to Fig. 1, Fig. 3 and Fig. 4, this lampshade 10 is made into integration by transparent or semitransparent material, and this lampshade 10 is provided with printing opacity scattering material (not shown).This lampshade 10 comprises sidewall 12 and roof 11, and this sidewall 12 is tubular and is connected with this roof 11.The middle part of this roof 11 protrudes out formation light-reflecting portion towards described LED light source 21, and this light-reflecting portion reflects towards this sidewall 12 for the part light that described LED light source 21 is sent.
The size of this sidewall 12 is 0.7-1.2 with the scope of the ratio of the size of this lamp body 30, and this sidewall 12 arranges the periphery of described LED light source 21.This roof 11 is conical platy structure, and directly over the LED light source 21 described in this roof 11 is positioned at, and the area of this roof 11 is greater than the described shared area of LED light source 21.
Because the buckling parts 311 of this body 31 is through the button hole on this radiating piece 32, this light source board 20 is compressed to the end face of this radiating piece 32, therefore this body 31 can firmly be assembled together with this radiating piece 32, and this light source board 20 can be firm the top that is fixed on this lamp body 30, difficult drop-off.Because these lampshade 10 bottoms are provided with fastening structure, coordinate with the buckling parts 311 of this lamp body 30, make the stable connection of this lampshade 10 and this lamp body 30, difficult drop-off.Because this buckling parts 311 is elastomeric material, therefore, when spiral-lock coordinates, this buckling parts 311 can be realized micro-strain and bear certain pressure, avoids buckling parts 311 fractures.
This big-angle LED lamp 100 is when work, because this radiating piece 32 is set in this body 31 peripheries, and top is provided with, and area is greater than the contact-making surface of this light source board 20 and this light source board 20 forms thermally coupled, make the heat that this light source board 20 sends to transmit rapidly and outwards to distribute, radiating effect is better.Because the middle part of this roof 11 protrudes out formation light-reflecting portion towards described LED light source 21, this light-reflecting portion reflects towards this sidewall 12 for the part light that described LED light source 21 is sent, and this lampshade 10 is made by transparent or semitransparent material, therefore part light is gone out from these lampshade roof 11 direct projections, and this just makes this big-angle LED lamp 100 have larger lighting angle.Because this lampshade 10 is provided with printing opacity scattering material, and this roof 11 is the shared area of described LED light source 21 for area is greater than, this roof 11 is conical platy structure, therefore, this lampshade 10 is wall thickness housing comparatively uniformly, this lampshade is by the light that outwards this LED light source 21 of scattering sends equably, and this light that just makes this big-angle LED lamp 100 send can be uniformly distributed in illumination zone, has avoided dark area effect.
In sum, this big-angle LED lamp 100 is by arranging the structure of this lampshade 10, the middle part of this roof 11 is protruded out to formation light-reflecting portion towards described LED light source 21, the part light that this light-reflecting portion is sent described LED light source is reflected towards the sidewall 12 of this lampshade 10, simultaneously, can make again part light go out from roof 11 direct projections, reflection forms with the acting in conjunction of direct projection the wide-angle needing.Because this roof 11 is provided with printing opacity scattering material for conical platy structure, area are greater than described LED light source 21 area occupied and this lampshade 10, can guarantee that the brightness of illumination of this big-angle LED lamp 100 is even, avoid forming hot spot and dark area effect.Owing to effectively simplifying the structure, make this big-angle LED lamp 100 have advantages of good heat dissipation effect, simple in structure, be convenient to manufacture.
Understandable, the radiating piece 31 of this lamp body 30 is mainly used in transferring heat, in the situation that meeting heat radiation requirement, can not be also the sheathed structure in embodiment.The buckling parts 311 of this lamp body 30 is mainly used in fixing this light source board 20 and this lampshade 10, and meeting firmly this light source board 20 and this lampshade 10, and be convenient to manufacture, can not also the spiral-lock fixed structure in embodiment.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of making, be equal to replacement, improvement etc., within all should being included in the scope of the utility model protection.
