Abstract
The invention discloses an LED (light-emitting diode) lamp which comprises a reflection cup, a light guide column and an LED device, wherein the reflection cup is provided with a central hole, the light guide column is mounted in the central hole, the LED device is coupled with the light guide column and positioned on the outer side of the reflection cup, and the light guide column is positioned on the inner side of the reflection cup, is an axially symmetric solid made of transparent materials and axially slides relative to the reflection cup. Various light-emitting angles of one lamp can be realized and even can be continuously adjusted by adjusting the position of the light guide column in the direction of an optical axis.
Description
Technical field
The present invention relates to a kind of LED lamp.
Background technology
Use in the market LED light fixture generally can directly see light source, dazzle is serious.And low-angle light cannot be controlled by reflector from the direct ejaculation of light source, general way is to increase the reflector degree of depth, though can alleviate.But volume just becomes larger simultaneously, cannot meet Design of Luminaires requirement.
Summary of the invention
The object of the invention is to overcome the defect existing in prior art, a kind of LED lamp is provided, do not have direct glare to produce, and near low-angle light light source normal direction also can be effectively controlled.
For achieving the above object, technical scheme of the present invention has been to provide a kind of LED lamp, comprise there is the reflector of centre bore, the LED luminous component that is installed on light-guiding pillar in described centre bore, is coupled with described light-guiding pillar, described LED luminous component is positioned at the outside of described reflector, the part of described light-guiding pillar is positioned at the inner side of described reflector, the axial symmetry entity that described light-guiding pillar is made by transparent material, described light-guiding pillar along it axially and the setting of sliding mutually of described reflector.
As preferably, described light-guiding pillar is cylindric.
As preferably, described light-guiding pillar is made by glass or optical resin material.
As preferably, described LED luminous component comprises LED substrate, is installed on the LED chip on described LED substrate.
As preferably, described reflector inner surface is coated with reflectance coating.
Advantage of the present invention and beneficial effect are: by regulating the position of light-guiding pillar on optical axis direction, can realize 1 section of multiple rising angle of light fixture, and even rising angle is adjustable continuously.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present invention.
Wherein: 1, reflector; 2, light-guiding pillar; 3, LED substrate; 4, LED chip.
The specific embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is further described.Following examples are only for technical scheme of the present invention is more clearly described, and can not limit the scope of the invention with this.
As shown in Figure 1, a kind of LED lamp, comprise the reflector 1 with centre bore, be installed on the light-guiding pillar 2 in described centre bore, the LED luminous component being coupled with described light-guiding pillar 2, described LED luminous component is positioned at the outside of described reflector 1, the part of described light-guiding pillar 2 is positioned at the inner side of described reflector 1, the axial symmetry entity that described light-guiding pillar 2 is made by transparent material, described light-guiding pillar 2 along it axially and the setting of sliding mutually of described reflector 1, described light-guiding pillar 2 is cylindric, described light-guiding pillar 2 is made by glass or optical resin material, described LED luminous component comprises LED substrate 3, be installed on the LED chip 4 on described LED substrate 3, described reflector 1 inner surface is coated with reflectance coating.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of the technology of the present invention principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
