Abstract
The invention relates to a reflector of a lamp, belonging to the technical field of parts of illumination lamps. The reflector of the lamp comprises a cover body which is provided with an outward convex surface, an inward concave surface as a reflection surface and a transparent opening. A mounting plane is formed on at least one side of the outward convex surface of the cover body, and a through hole communicated with the inside and outside of the cover body is formed on the mounting plane. An inward convex enhanced reflection section with a certain length is formed on the top of cover body, wherein the inward convex enhanced reflection section is concave towards an inward concave surface from an outward convex surface. The inward convex enhanced reflection section comprises two side surfaces with two lower edges intersected with each other; the intersection of the two side surfaces forms an intersection edge; and each side surface is respectively in a cambered surface structure or consists of a plurality of planes.
Description
Technical field
The present invention relates to a kind of light fitting reflecting cover, belong to the lighting technical field of parts.
Background technology
The reflecting surface of existing light fitting reflecting cover is single globoidal structure more, and (notification number: CN201043715), comprise substrate and the reflector that is covered in the substrate inner surface, reflector is made up of nano-coating face coat and base plate as a kind of light fitting reflecting cover.Adopt the nano-coating face coat to help reducing the energy loss of the each reflection of light, but there are the following problems for the reflection shield of said structure: the light source that the is positioned at reflection shield particularly light of upwards penetrating that sends of planar light source has been mapped to the light source surface again after by the reflection of the reflecting surface of reflection shield, stopped that by light source self extinction strengthens light-source temperature and reduces the life-span, and can not penetrate from the light openings of reflection shield, penetrate light perhaps and will consume major part through reflexing to last ejaculation light openings energy many times, reflecting effect is relatively poor, cause Luminaire efficiency not high, the light that does not have to realize upwards penetrating is through the least possible order of reflection, just penetrate light openings as main through primary event or two secondary reflections, make the few purpose of light reflected energy loss.
Summary of the invention
Particularly the reflector reflecting effect of area source is relatively poor to the invention solves the existing in prior technology light source, causes the lower problem of Luminaire efficiency, provides a kind of reflecting effect good, the light fitting reflecting cover that Luminaire efficiency is higher.
Above-mentioned technical purpose of the present invention solves by the following technical programs: it comprises cover cap shape body, described cover cap shape body has convex surface and as the concave surface and the light openings of reflective surface, at least one side of convex surface of cover cap shape body is formed with mounting plane, described mounting plane is formed with and is communicated with the through hole that covers this inside and outside of shape, the convex that described cover cap shape bodies top is formed with by the recessed surface that concaves of convex surface strengthens reflecting part, convex strengthens reflecting part and has certain-length, described convex strengthens reflecting part and comprises two sides that lower edge crosses and links together, two sides cross and form the limit that crosses, and each side is globoidal structure respectively or is formed by connecting by several planar portions.Convex of the present invention strengthens reflecting part can will go up most light of directive reflector central part only through once or via concave surface reflecting light openings through twice directly over the whole light source, thereby the light that light source is sent penetrates from light openings to greatest extent, reduce the light waste, improve the efficiency of light fixture, strengthen the illuminance of light fixture.Wherein, convex strengthens each side of reflecting part to be adopted globoidal structure respectively or is connected to form the reflection path that can reduce light by several planar portions, reduces the light energy decay, improves light efficiency.Wherein, the through hole on the mounting plane is used light source is incorporated in the reflection shield.
As preferably, described two sides are the mirror image symmetry with the plane of crossing the limit that crosses, thus the light that light source is upwards penetrated launch uniformly via two sides that convex strengthens reflecting part, improve the uniformity of light openings light.
As preferably, described two sides include last plane and the lower flat portion that interconnects, and the angle between the last planar portions of two sides is 60 °-120 °, and the angle between the lower flat portion of two side faces is 5 °-55 °.Wherein, because the lower plane of two sides more is close to light source, and the light that needs big more angle of reflection light source could be sent the closer to the position of light source reflects away, then need littler angle of reflection that light is reflected away from light source is far away more, so the present invention is controlled at 5 °-55 ° with the angle of the lower plane of two sides, can guarantee that convex strengthens emission part and plays light source emit beam shorter reflection path and more efficiently reflection and the angle between the last plane of two sides is controlled at 60 °-120 °, improve efficiency.
As preferably, the angle between the last planar portions of described two sides is 80 °-100 °, and the angle between the lower flat portion of two side faces is 25-35 ° and has better effect.
As preferably, the top of described lid shape body convex surface is contour structure, and described convex strengthens reflecting part, and sectional dimension is little identical everywhere.This kind structure is particularly useful for Tunnel Lamp, floodlight, street lamp etc., and the top of lid shape body convex surface is contour structure, and convex strengthen reflecting part everywhere the little identical light that guarantees that light source sends of sectional dimension after the reflection shield reflection, penetrate from light openings.
As preferably, high two ends were low in the middle of the top of described lid shape body convex surface was, and dark two ends were shallow in the middle of the outer surface that described convex strengthens reflecting part was.This kind structure is particularly useful for the light fixture of the big light angle of needs, as street lamp, in the middle of the top of lid shape body convex surface is the low and convex in high two ends strengthen reflecting part be in the middle of the shallow light that light source is sent in dark two ends after the reflection shield reflection, penetrate from light openings.
As preferably, the length direction that described convex strengthens reflecting part extends to opposite side with respect to mounting plane from mounting plane one side of covering the shape body, has enough length thereby can make convex strengthen reflecting part, to improve the reflecting effect of the light that light source is upwards penetrated.
As preferably, the limit that crosses that described convex strengthens two sides of reflecting part is close in the top edge that is formed on the through hole on the described mounting plane, strengthens the reflection path of reflecting part to source light thereby can shorten convex, avoids reverberation directive light source, reduces light decay.
As preferably, the limit that crosses that described convex strengthens two sides of reflecting part is 0.1mm-20mm with the distance L that is formed on the top edge of the through hole on the described mounting plane.
As preferably, described convex strengthens the convex surface top that reflecting part is centered at the cover cap body and is provided with, thus the light that light source is upwards penetrated launch uniformly via two sides that convex strengthens reflecting part, improve the uniformity of light openings light.
As preferably, the convex surface of described cover cap shape body is provided with the heat radiation fin parallel with the limit that crosses.Wherein, radiating fin can strengthen the radiating effect of the light source in the reflection shield, reduces light decay.
Therefore, it is good that the present invention has a reflecting effect, Luminaire efficiency height, the characteristics that illuminance is good.
