Abstract
An optical structure of an LED tube lamp comprises a reflector bowl and an LED light source. The LED tube lamp comprises a radiator, wherein a groove is formed in the radiator, the reflector bowl is arranged in the groove, a flange is arranged on the edge of the top portion of the reflector bowl, an annular pressing plate is arranged between the flange and the radiator, a circular light emitting opening is formed in the middle of the annular pressing plate, and the diameter of the light emitting opening is larger than that of an opening in the top portion of the reflector bowl. The edge of the top portion of the reflector bowl is not covered by the pressing plate, and therefore the reflector bowl can reflect all reflect light, and the light utilization rate of the optical structure is increased.
Description
Technical field
The utility model relates to LED lighting field, especially a kind of LED Down lamp optical texture.
Background technology
Existing LED Down lamp generally comprises radiator, reflector, LED light source and pressing plate, pressing plate is used for fixedly reflector, inside existing pressing plate, rim can hide the top of reflector, thereby cause the light of reflector top not irradiate out, reduce the diameter of hot spot, reduced the utilization rate of Down lamp light.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of LED Down lamp optical texture, and reflector is higher to the utilization rate of light.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of LED Down lamp optical texture, comprise reflector and LED light source, described LED Down lamp comprises radiator, and described radiator is provided with groove, and described reflector is installed in described groove, described reflector top is provided with flange, between described flange and radiator, be provided with annular pressing plate, the conglobate light-emitting window of shape in the middle of described annular pressing plate, the diameter of described light-emitting window is greater than reflector open top diameter.The utility model is because the top of reflector is not hidden by pressing plate, so reflector can, by all reflective reflecting, improve its utilization rate to light.
As improvement, the diameter of described light-emitting window is than the large 2 ~ 4mm of reflector open top diameter.
As improvement, described LED light source is high-power COB.
As improvement, the bottom of described reflector is provided with connecting plate, and described connecting plate centre position is provided with the installing port for installing for LED light source.
The beneficial effect that the utility model compared with prior art brought is:
The utility model is because the top of reflector is not hidden by pressing plate, so reflector can, by all reflective reflecting, improve its utilization rate to light.
Accompanying drawing explanation
Fig. 1 is Down lamp decomposition view.
Fig. 2 is Down lamp top view.
Fig. 3 is reflecting bowl structure schematic diagram.
The specific embodiment
Below in conjunction with Figure of description, the utility model is described in further detail.
As shown in Figure 1, a kind of LED Down lamp optical texture, described LED Down lamp comprises radiator 3, described radiator 3 is provided with groove 4; Described optical texture comprises reflector 2 and LED light source 5.As shown in Figure 3, described reflector 2 is installed in described groove 4, and described reflector 2 top are provided with flange 21, between described flange 21 and radiator 3, are provided with annular pressing plate 1, thereby described pressing plate 1 is fixed reflector 2 by compressing the flange 21 of reflector 2.As shown in Figure 2, the conglobate light-emitting window of shape in the middle of described annular pressing plate 1, the diameter of described light-emitting window is greater than reflector 2 open top diameters, and in the present embodiment, the diameter of described light-emitting window is than the large 2 ~ 4mm of reflector 2 open top diameter.The bottom of described reflector 2 is provided with connecting plate 22, and described connecting plate 22 centre positions are provided with the installing port 23 for installing for LED light source 5, and connecting plate 22 is connected with groove 4 bottoms by glue.Described LED light source 5 is high-power COB.
The utility model is because the top of reflector 2 is not hidden by pressing plate 1, so reflector 2 can, by all reflective reflecting, improve its utilization rate to light.
