Detailed description of the invention
Core of the present utility model is to provide a kind of light reflection device of LED light fixture, and mirror lens leaks light, to improve the efficiency of light energy utilization.
In order to make those skilled in the art person understand better the utility model scheme, below in conjunction with drawings and embodiments, the utility model is described in further detail.
Please refer to shown in Fig. 1 and Fig. 2, the utility model embodiment discloses a kind of light reflection device of LED light fixture, the light of revealing for mirror lens 1, and it comprises: reflective body 2 and reflecting layer.
Wherein, reflective body 2, as the major part of reflection unit, is located at the outside of lens 1, and and lens 1 between form the cavity of reflection ray, for collecting the light of revealing from the side of lens 1.
And reflecting layer is as the core component of its reflex, realize the object that collection is penetrated from lens 1 more again of the light that the side from lens 1 is revealed, complete the reflex of light reflection device.
When work, LED light fixture sends light, and scioptics 1 are irradiated to the external world, realize the function of illumination, and the light of revealing from the side of lens 1 is irradiated to reflecting layer, and through the reflection in reflecting layer, again be irradiated to the external world from lens 1, the light of revealing is utilized, has reduced light loss, improved the efficiency of light energy utilization.
Preferably, reflecting layer is set to be arranged on mirror process layer, polishing layer or the electroplating processes layer on reflective body 2 inwalls.Can reflection ray in order to realize light reflection device, in concrete operations, can carry out mirror process, polishing or electroplating processes to the inwall of reflective body 2, can make the inner wall smooth of reflective body 2 reflective.In addition, also can on the inwall of reflective body 2, brush the reflectorized material with reflection action, for example fluorescent material.Also can directly on the inwall of reflective body 2, paste reflex reflector lens, as long as can realize reflective.
Further, in embodiment, reflective body 2 and lens 1 are removably connected.By being connected of reflective body 2 and lens 1, can prevent that light reflection device and lens 1 position are offset, and have improved the stability of whole LED lamp.By removably connecting, can in the time that damaging, lens 1 or reflective body 2 change, to improve the service life of this LED lamp, avoid waste.Also the formula structure that lens 1 and light reflection device can be processed as one in actual production or directly both are welded on to one.
Particularly, one end of reflective body 2 is provided for to card and establishes the buckle 21 of the draw-in groove of lens 1, when light reflection device is installed, the buckle of reflective body 2 21 is buckled in the draw-in groove of lens 1, to realize being connected of reflective body 2 and lens 1.Be specially the projection being arranged on reflective body 2 for the form of buckle 21, and this projection can enter in the draw-in groove being opened on lens 1 under the effect of self toughness, and coordinate with draw-in groove, to realize spacing to buckle of draw-in groove, realize and connecting.Only be to provide a kind of concrete connected mode herein, in practice, also reflective body 2 can be connected by gluing mode with lens 1.
