The specific embodiment
In order to make the object of the invention, technical scheme and advantage clearer,, the present invention is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.
The embodiment of the invention is designed to multilayer terrace with edge face with the inner surface of reflector; Direction along beam projecting; Angle between the adjacent two layers terrace with edge face increases successively, makes on the axis that is centered close to reflector of light source, and the light that light source sends mixes in the field of illumination after the reflection of multilayer terrace with edge face; Illumination is even, and Luminaire efficiency is high.
The inner surface of the reflector that the embodiment of the invention provides is made up of multilayer bottom surface and end face the terrace with edge face of adjacency successively, and along the exit direction of light, the angle between the adjacent two layers terrace with edge face increases successively, on the axis that is centered close to said reflector of light source.
The Down lamp that the embodiment of the invention provides comprises above-mentioned reflector and is located at the light source in the above-mentioned reflector.
The illuminator that the embodiment of the invention provides comprises above-mentioned Down lamp.
Be that example is described in detail realization of the present invention below with the Down lamp.
Shown in Fig. 1～4, the Down lamp that the embodiment of the invention provides comprises reflector 1 and the light source of being located in the reflector 12, on the axis that is centered close to reflector 1 of this light source 2.The inner surface of reflector 1 is made up of multilayer terrace with edge face in the embodiment of the invention, and along the exit direction of light, the angle between the adjacent two layers terrace with edge face increases successively.The light that light source 2 sends mixes in the field of illumination after the reflection of multilayer terrace with edge face, and illumination is even, and Luminaire efficiency is high.
Above-mentioned terrace with edge face is the side of positive terrace with edge.The inner surface of reflector 1 constitutes 2≤N≤5 by N layer terrace with edge face; And the number that M has determined each layer terrace with edge face is counted, 8≤M≤14 in the limit of the bottom surface of positive terrace with edge.Whole reflector 1 promptly has M * N terrace with edge face, and the light that light source 2 is sent is divided into M * N part, and each several part light mixes in the field of illumination, and illumination is even, makes light soft.Through angle between the adjusting adjacent layer terrace with edge face or the angle between each layer terrace with edge face and the reflector bottom surface, reach half required light intensity angle.
In the embodiment of the invention, the inner surface of reflector 1 is made up of two-layer terrace with edge face, and the limit number of the bottom surface of positive terrace with edge is 12, promptly has 12 first terrace with edge faces 11 and 12 second terrace with edge faces 12.The length of the incline of the first terrace with edge face 11 is 38.7mm, and the angle of the bottom surface 13 of itself and reflector is 134.9 °; The length of the incline of the second terrace with edge face 12 is 81mm, and the angle β of the incline of itself and the first terrace with edge face 11 is 168.5 °.The bright dipping bore of reflector 1 i.e. each base length sum of the second terrace with edge face is 235.5mm.
This Down lamp adopt power be the transparent Metal halogen lamp of 150W as light source 2, the bottom surface 40mm of the centre-to-centre spacing reflector of this light source 2.The luminous flux of surveying transparent Metal halogen lamp (naked light source) is 130001m, and the luminous flux of Down lamp outgoing is 100531m, and Luminaire efficiency is promoted to 77.3%, is beneficial to reducing energy consumption; Nearly 80 ° of half light intensity corner connection, as shown in Figure 5, illumination is even in this light intensity angular region, satisfies the requirement to luminous intensity distribution fully.
Certainly, above-mentioned reflector 1 also can constitute Down lamps with dusting Metal halogen lamp, electricity-saving lamp, electrodeless florescent lamp etc.Correspondingly, the inner surface of reflector 1 is made up of two-layer terrace with edge face, and the limit number of the bottom surface of positive terrace with edge is 10, promptly has ten first terrace with edge faces 11 and ten second terrace with edge faces 12, like Fig. 6 and shown in Figure 7.
Be to improve reflectivity, reflector 1 is processed by highly reflective materials such as rafifinals.Adopt spinning block spinning during making earlier, form through the sizing die shaping, technology is simple, and cost is low.
The embodiment of the invention is designed to multilayer terrace with edge face with the inner surface of reflector; Direction along beam projecting; Angle between the adjacent two layers terrace with edge face increases successively, makes on the axis that is centered close to reflector of light source, and the light that light source sends mixes in the field of illumination after the reflection of multilayer terrace with edge face; Illumination is even, and Luminaire efficiency is high.Adopt the lens Metal halogen lamp as light source simultaneously, process nearly 80 ° of the half light intensity corner connection of Down lamp, illumination is even in this light intensity angular region, satisfies the requirement to luminous intensity distribution fully.In addition, reflector adopts spinning block spinning earlier, forms through the sizing die shaping again, and technology is simple, and cost is low.
The above is merely preferred embodiment of the present invention, not in order to restriction the present invention, all any modifications of within spirit of the present invention and principle, being done, is equal to and replaces and improvement etc., all should be included within protection scope of the present invention.
