Description
Technical field
This utility model relates to a kind of big-angle LED lamp, divides by International Patent Classification (IPC) (IPC) and belongs to LED technical field.
Background technology
Existing A steeps the LED such as lamp, bulb lamp, G lamp and all adopts band lens, reflector or lens+reflector design so that lighting angle is fully achieved wide-angle 270 degree. There is following defect:
(1) cost is high;
(2) complex manufacturing, one by one mounted lens/reflector, lampshade;
(3), during luminescence, have dark space in some position of lampshade, become apparent from during light modulation;
(4) it is consider light source arrangement problem from optical angle when design lens or reflector, can indirectly make light-source temperature higher.
A kind of big-angle LED lamp disclosed in China patent document application publication number CN103256505A, reflector that all can be reflective including lamp plate and inside and outside surface, the lower end of reflector is arranged on lamp plate, and is equipped with LED light source on the lamp plate that reflector lower end is inside and outside. The light that LED light source within reflector sends carries out reflecting, reflecting through reflector inner surface, thus increasing rising angle; The light that LED light source outside reflector lower end sends carries out reflecting, reflecting through reflector outer surface, increases rising angle further, thus LED that a wide-angle luminous is integrally formed; Said structure, by reflecting after reflecting, can be only achieved large angle illumination, and structure is complex, causes production and processing difficulty.
China patent document application publication number CN103912811A discloses a kind of big-angle LED lamp, including lamp holder, heat radiating cup, LED light source module, power module and reflection shield, LED light source module includes LED-baseplate and the LED chip being arranged in LED-baseplate, described heat radiating cup inner hollow, LED-baseplate is fixed on the end face of heat radiating cup, reflection shield stands in LED-baseplate and reflection shield inner space keeps communicating with heat radiating cup inner space, a reflection shield is added in the middle of described LED-baseplate, light alignment surrounding is made to spread, simultaneously, reflection shield is communicated by the present invention with heat radiating cup, make use of the inner space of reflection shield, part components and parts in power module are placed in inside reflection shield, solve and cause the little problem that cannot place of power source space because of large lampshade, said structure adopts reflection shield to realize large angle illumination equally, time luminous, have dark space in some position of lampshade, becomes apparent from during light modulation.
Therefore, in existing LED, existing cost height, complex manufacturing, dark space and one of important topic of research staff in indirectly making light-source temperature higher etc. to be the LED lamp structure of current wide-angle luminescence realizing existing in the LED that wide-angle is luminous how is solved.
Utility model content
For the deficiencies in the prior art, this utility model provides a kind of big-angle LED lamp, and it mainly solves cost height in prior art, complex manufacturing, dark space and the technical problem such as can indirectly make light-source temperature higher.
For reaching above-mentioned purpose, this utility model is achieved through the following technical solutions:
A kind of big-angle LED lamp, it includes lamp holder, mould shell, plate, LED light source plate and lampshade in aluminum, and LED light source plate is arranged in aluminum on plate, and in aluminum, plate is arranged on and moulds shell one end, and lamp holder with mould shell two one end and be connected, described lampshade is fastened on to be moulded shell one end and is radiated in lampshade by LED light source plate; Described lampshade is provided with the certain thickness reflection oxidant layer with semi-transflective reflective performance.
Further, described reflective agent layer thickness is gradually reduced from lampshade top to its week side, in order to realize large angle illumination.
Further, described reflective agent layer thickness is gradually reduced from lampshade top to its week side, in order to realize large angle illumination.
Further, described reflection oxidant layer is sprayed on lampshade inner surface.
Further, described reflection oxidant layer is positioned at thickness, lampshade top and reaches 0.1mm��0.3mm, and thinnest part reaches 0.05mm��0.1mm
Further, this LED also includes the radiator that is fixed in aluminum on plate by glue-line.
Compared with prior art, advantage of the present utility model:
1, this utility model utilizes the semi-transflective reflective performance of reflective dose, sprays the reflective oxidant layer of certain thin and thick on lampshade, from lampshade top down thickness step-down gradually, it is achieved lighting angle fullys meet wide-angle 270 degree;
2, lampshade is in process of production, and fixing on a heat sink either directly through glue, technique is simple;
3, adopt the lampshade of reflective dose of spray, time luminous, do not have dark space;
