In the utility model preferred embodiment, the thickness of described highly reflecting films is less than 1mm.

The utility model solves the defect existed in background technology, and the utility model has following beneficial effect:

(1) by the Angle ambiguity between reflector and lamp bracket, the light sent by LED is gone out by the reflected illumination of reflector, and distribution of light is more evenly soft, and brightness is also improved, and distribution curve flux figure is comparatively full.

(2) by arranging the corresponding reflector of two groups of LED lamp bar or arranging the corresponding reflector of one group of LED rule etc., and LED lamp bar is configured in reflector side or the situation such as is configured in the middle of reflector, different types of light fixture is carried out to the corresponding adjustment of different angles and position, different needs can be met.

(3) reflector is arcuate structure with the cross section of highly reflecting films part, the light that LED can be realized to send arcuately is gone out by soft reflections in face, the light that can realize LED sends carries out integrally-regulated effect, by light reflection in a specific region, and the difference realizing light intensity in this region is distributed.

(4) the loose structure lamellar structure that macromolecule silk composition is fine and close, the light fundamental reflection entered in the unordered spinning layer of macromolecule can be gone out, and after the reflection of the unordered spinning layer of macromolecule, light is diffusely reflected away, and the light simultaneously entered in the unordered spinning layer of macromolecule substantially can not by absorption loss.

(5) highly reflecting films are provided with the unordered spinning layer of layer high molecule, avoid light and are not easily occurred by situation about reflecting by the unordered spinning layer of one deck macromolecule, substantially increase reflectivity, be greater than 99% by the light reflected.

(6) fiber number of macromolecule silk is below micron order and micron order, the macromolecule silk of this kind of scale dimensions can realize the reflection to light, and light can not be absorbed, light only has reflection entering in the unordered spinning layer of macromolecule, does not have the phenomenon absorbed to occur.

(7) highly reflecting films are attached on the base plate on reflector, even if light is want also to be blocked reflection by base plate, so doing so avoids the situation of light by reflector through the unordered spinning layer of all macromolecules.

(8) fiber number of macromolecule silk becomes large gradually by internal layer outer layers, and ensure that light is at the not identical reflectivity of the unordered spinning layer of different macromolecule and conditioned reflex, the light made can be reflected as early as possible.

Detailed description of the invention

Be described in further detail the utility model in conjunction with the accompanying drawings and embodiments now, these accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.

As Figure 1-3, a kind of illuminating lamp with secondary reflection reflector, comprise: be arranged on the LED2 on lamp bracket 1, and LED2 light irradiate towards reflector 3, reflector 3 surface is with one deck highly reflecting films, the light of LED2 shines directly on the highly reflecting films of reflector 3, and the light of LED2 can reflect away from light fixture light-emitting window by reflector 3, and the central ray angle of the central ray that LED2 emits beam and the light that light-emitting window shines out is 45 °-180 °.LED2 is back to lamp bracket 1, by light full illumination on reflector 3, by the reflection of reflector 3, there is 45 °-180 ° turning in opticpath, and shone out by the light-emitting window of light fixture, the pipeline direct irradiation that this kind of technical scheme avoids LED2 go out produce dazzle optical phenomenon, simultaneously, through diffuse reflection process and the luminous intensity distribution process on reflector 3 surface, light can be gone out according to rising angle range illumination more uniformly.

By the Angle ambiguity between reflector 3 and lamp bracket 1, the light sent by LED2 is gone out by the reflected illumination of reflector 3, and distribution of light is more evenly soft, and brightness is also improved, and distribution curve flux figure is comparatively full; By arranging the corresponding reflector 3 of two groups of LED2 lamp bars or arranging the corresponding reflector 3 of one group of LED2 lamp rule etc., and LED2 lamp bar is configured in reflector 3 side or the situation such as is configured in the middle of reflector 3, different types of light fixture is carried out to the corresponding adjustment of different angles and position, different needs can be met.

In a kind of embodiment of the present utility model, reflector 3 is arc 4 structure with the cross section of highly reflecting films part, and the light of LED2 can be evenly distributed to each region by the curved surface of arc 4, and light intensity is comparatively even, does not have dazzling phenomenon.

Lamp bracket 1 of the present utility model is provided with two, is respectively located at reflector 3 both sides of the edge, and the LED2 on lamp bracket 1 irradiates in the middle part of reflector 3.

Lamp bracket 1 is provided with shadow shield, shadow shield has highly reflecting films towards reflector 3 one side, the light reflection that LED2 can irradiate towards light-emitting window by shadow shield is on reflector 3, the effect that shadow shield plays LED2 is shone directly into light reflection outside light-emitting window on reflector 3, shine out after having reflector 3 diffuse reflection, avoid dazzling.

Highly reflecting films by macromolecular material reel off raw silk from cocoons layer spread form loose structure, the macromolecular material sprawled layer by layer is loss luminous energy hardly, light is illuminated enter after be diffusely reflected, finally can be reflected.
