Referring to fig. 1 and 2, an embodiment of the present invention provides a lamp.
In this embodiment, the lamp includes: housing 400, light source 110, lens 200, and reflector 300.
The housing 400 may be a tubular structure made of a transparent material, and may be a transparent material or a semitransparent material. So that light emitted from the light source 110 and light reflected by the reflective cover 300 can pass through the outer cover 400. Both ends of the outer cover 400 may be open, one end may be closed by the lamp socket, and the other end may be closed by the reflective cover 300. The light source 110 and the lens 200 are both disposed within the housing. The light source 100 is disposed at a side of the lens 200 away from the reflective cover 300, and emits light to the other end of the cover 400. That is, the reflector 300 and the light source 110 are disposed oppositely, the lens 200 is disposed therebetween, and the light source 110, the lens 200 and the reflector 300 are disposed coaxially, so that the lamp is a candle lamp, in this embodiment, a part of light emitted by the light source 110 passes through the lens 200 and then is reflected by the reflector 300 onto a plane on which the lamp is disposed, so as to create a romantic atmosphere. The light source 110 may be a single light source or a plurality of light sources, and the light source 110 may be an LED lamp.
The lens 200 may be made of PMMA (polymethyl methacrylate). The PMMA has high transparency, thereby improving the utilization of the lens 200. The lens 200 includes a concave lens body 210 and a light-gathering part 220, wherein the concave lens body 210 is a double-sided concave lens, and a side facing the light source 110 is a light-incident side and has a concave first incident surface, and at least a central part of the incident surface is a paraboloid or a spherical surface. The side of the concave lens body 210 facing away from the light source 110 is a light-emitting side having a concave light-emitting surface, and the light-emitting surface is a paraboloid or a sphere. The partial spherical surface of the first incident surface protrudes toward the light source 110 to form the condensing portion 220, thereby forming a convex lens structure at the center of the incident surface.
As can be easily understood, referring to fig. 5, after the light source 110 passes through the concave lens body 210, the light is diffused significantly, most of the light generated by the light source 110 is not collected on the reflector 300, but directly passes through the outer cover 400 to be diffused into the environment around the lamp, and only part of the light generated by the light source 110 is projected onto the plane where the lamp is placed by the reflector 300, so that the projected light spot on the plane is small and the dark area is large.
In the embodiment, referring to fig. 3, the light-gathering portion 220 is formed by protruding the first incident surface of the concave lens body 210, the light-gathering portion 220 is disposed to change the lens structure from a concave lens to a convex lens to gather light, so as to reduce the light-emitting angle of the lamp, and to gather most of the light emitted by the light source 110 to the reflector 300 by the lens 200, and further to be projected to the plane where the lamp is located and form a large projection spot in the circumferential direction of the lamp, and since more light is projected to the plane where the lamp is located, the dark area in the projection spot is reduced.
In one embodiment, a side of the light-condensing portion 220 facing the light source 110 has a second incident surface, and the second incident surface is configured as a curved surface. The curved surface may be a paraboloid or a sphere, and may also be a free-form surface.
In one embodiment shown, the second entrance face is provided as a spherical surface; referring to fig. 2 and 3, a light emitting surface 211 is disposed on a side of the concave lens body 210 away from the light source 110, an included angle between a connection line from any point on the edge of the second incident surface to a curvature center of the light emitting surface and a central axis of the light source 110 is a, and a is greater than or equal to 6.5 degrees and less than or equal to 7.5 degrees. For example, a is 7 °, and in the direction of the central axis, the distance d between the geometric center of the second incident surface and the incident surface is greater than or equal to the thickness b of the concave lens body 210, and d and b satisfy: d ≧ b, e.g., d ≧ b.
In another embodiment shown, in order to further reduce the light emission angle, a second incident surface, which is an incident surface of the light condensing portion 220 from which light emitted from the light source enters the lens 200, is provided as a free-form surface. At this time, referring to fig. 4, a side of the concave lens body 210 facing away from the light source 110 has a light emitting surface 211, an included angle between a connection line from any point on the edge of the second incident surface to a curvature center of the light emitting surface and a central axis of the light source 110 is a, and a satisfies 6.5 ° or more and 7.5 ° or less, for example, a is 7 °, and in a direction in which the central axis is located, a distance c between a geometric center of the second incident surface and the incident surface is twice as large as a thickness b of the concave lens body 210, and c and b satisfy: c ≧ 2b, e.g., c ≧ 2 b. In this embodiment, referring to fig. 7, by using free-form surface collimation, the lens further reduces the light emitting angle, so that more light rays are collected by the lens 200 onto the reflector 300 and further projected onto the plane where the lamp is located and form a larger projection light spot in the circumferential direction of the lamp, and as more light rays are projected onto the plane where the lamp is located, the dark area in the projection light spot is further reduced.
In one embodiment, the reflective cover 300 is formed to protrude toward one side surface of the lens to form a reflective protrusion 310, and the surface of the reflective protrusion is configured to be a curved surface. The reflective protrusion 310 forms a convex mirror type on the reflective cover 300, and the convex mirror type reflective cover 300 reflects more light to the side of the lamp than to a plane mirror, instead of directly projecting the light onto the lens below the reflective cover 300, so as to form a brighter and larger projection light spot on the plane of the lamp by controlling the projection angle. As an alternative to this embodiment, the surface of the reflective convex portion 310 may be configured as a free-form surface, and may also be configured as a paraboloid or a sphere, which is not limited by this embodiment.
As an option of this embodiment, the reflective cover 300 is made of aluminum. And an aluminum oxide layer is provided on a surface of the reflective protrusion 310 facing the lens 200. Specifically, the aluminum reflecting spherical surface can be anodized, the reflectivity of the reflecting spherical surface is improved, and light rays are further projected to the side of the lamp, so that brighter and larger projected light spots are formed on the plane where the lamp is located.
In an embodiment, the lamp further includes a lamp panel 100, the lamp panel 100 is disposed in the housing 400, the lamp panel 100 is provided with a light source 110, wherein the color of the surface of one side of the lamp panel 100 facing the lens 200 is black, so as to eliminate visible color differences, prevent a user from seeing the internal structure of the lamp socket and other colors when looking straight at the lamp, and improve the viewing experience of the user. As an option of this embodiment, the surface of the lamp panel 100 facing the lens is provided with a black oil layer. Specifically, black oil is sprayed on the surface of the PCB lamp panel 100, thereby eliminating visible color differences inside the lamp. The lamp panel 100 may be a PCB board.
The above is only the optional embodiment of the present invention, and not the scope of the present invention is limited thereby, all the equivalent structure changes made by the contents of the specification and the drawings are utilized under the inventive concept of the present invention, or the direct/indirect application in other related technical fields is included in the patent protection scope of the present invention.
