Description
Technical Field
The utility model belongs to the technical field of the lamps and lanterns and specifically relates to a LED lamps and lanterns.
Background
At present, an LED spot lamp mainly comprises a power supply, a radiator, an LED light source and an LED lens. As shown in fig. 1, light emitted from the LED light source is emitted after secondary light distribution by the LED lens, and in the lamp with such a structure, the entire surface of the LED lens becomes the light emitting surface of the lamp, so that the light emitting area of the lamp is large, and the light emitting surface of the lamp has a large visual angle and a large glare.
SUMMERY OF THE UTILITY MODEL
The utility model discloses the technical problem that will solve is: an LED lamp is provided for reducing the area of a light emitting surface of the lamp.
The utility model provides a technical scheme that its technical problem adopted is: an LED lamp comprises a radiator, an LED light source and an LED lens, wherein the radiator comprises a body and an extension part extending from the body to the light emitting direction of the LED lens, and the body is used for fixing the LED light source and the LED lens; the extension part hides the LED lens in an inner space formed by the extension part, the extension part is further provided with an opening in front of the LED lens, the LED lens focuses light emitted by the LED light source in the opening, and the diameter of the opening is smaller than that of the LED lens.
Further, in order to make the position of the opening more reasonable, the opening should be located on the center line in front of the LED lens.
Further, the diameter of the opening is generally less than 0.5 times the diameter of the LED lens, and generally, the influence of a large viewing angle and a large glare can be significantly reduced after the diameter of the opening is less than 0.5 times the diameter of the LED lens.
The utility model has the advantages that: the utility model discloses an extension hides LED lens in the inner space that the extension formed to utilize LED lens to focus on the radiator extension with the light that the LED light source sent and set up in the trompil, LED lens is fine like this is hidden inside lamps and lanterns, has reduced the light-emitting area of LED lamps and lanterns again simultaneously, has reduced the visual angle on the surface of light is gone out to lamps and lanterns, has reduced the lamps and lanterns glare.
Drawings
FIG. 1 is a structure of an existing LED spotlight and a light path diagram corresponding to the structure;
fig. 2 is a structure of the LED spotlight fixture disclosed in the embodiment and a light path diagram corresponding to the structure.
The light source module comprises a heat sink 100, an LED light source 200, an LED lens 300, an opening 400, a body 101 of the heat sink, an extension 102 of the heat sink, a light incident side surface 301 of the LED lens, a reflecting wall 302 of the LED lens, a normal incidence surface 303 of the LED lens, and a light emergent surface 304 of the LED lens.
Detailed Description
In order to solve the problems of large light-emitting area of the existing LED lamp, large visual angle of the light-emitting surface of the lamp, and large glare, the utility model discloses an LED lamp, which comprises a radiator, an LED light source and an LED lens, wherein the radiator comprises a body and an extending part extending from the body to the light-emitting direction of the LED lens, and the body is used for fixing the LED light source and the LED lens; the radiator still includes by the body to the extension that the light-emitting direction of LED lens extends, the extension hides LED lens in the inner space that the extension formed, the extension is still in the place ahead of LED lens is provided with the trompil, LED lens with the light focus that the LED light source sent in the trompil, the diameter of trompil is less than the diameter of LED lens.
In order to enable the position of the opening to be more reasonable, the opening is located on a central line in front of the LED lens; the diameter of the opening can be smaller than 0.5 times of the diameter of the LED lens, and generally, the influence caused by a large visual angle and large glare can be obviously weakened after the diameter of the opening is smaller than 0.5 times of the diameter of the LED lens.
The present invention will be further described with reference to the following examples.
The embodiment discloses an LED lamp, as shown in fig. 2, including a heat sink 100, an LED light source 200, and an LED lens 300, where the heat sink 100 includes a body 101 and an extending portion 102 extending from the body 101 to a light emitting direction of the LED lens, and the body can fix the LED light source 200 and the LED lens 300; the extension part 102 hides the LED lens 300 in an inner space formed by the extension part, the extension part 102 is further provided with an opening 400 on a central line in front of the LED lens 300, the light emitting surface 304 of the LED lens 300 is a free-form surface, light emitted by the LED light source 200 can be focused in the opening 400 through the free-form surface, and the diameter of the opening 400 is smaller than that of the LED lens 300.
In the embodiment shown in fig. 2, when the LED light source 200 operates, light emitted from the LED light source is mainly divided into two parts, and one part of the light is refracted by the light incident surface 301 of the LED lens, then totally reflected by the reflective wall 302 of the LED lens, and then refracted by the light emitting surface 304 of the LED lens and focused in the opening 400; another part is refracted by the normal incidence surface 303 of the LED lens, and then refracted by the light emitting surface 304 of the LED lens and focused in the opening 400. The LED lens 300 focuses the light emitted from the LED light source 200 into the opening 400, so as to allow as much light as possible to exit from the opening 400 without being blocked by the lamp; the diameter of the opening 400 is smaller than that of the LED lens 300, so that the light emitting area of the LED lamp is reduced, the visual angle of the light emitting surface of the lamp is reduced, the glare of the lamp is reduced, and the light pollution is reduced.
