The specific embodiment
In order to make purpose of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
The embodiment of the present invention is designed to multilayer terrace with edge face by the inner surface of reflector, direction along beam projecting, angle between adjacent two layers terrace with edge face increases successively, make on the axis that is centered close to reflector of light source, the light that light source sends mixes in field of illumination after the reflection of multilayer terrace with edge face, uniform-illumination, Luminaire efficiency is high.
The inner surface of the reflector that the embodiment of the present invention provides consists 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 adjacent two layers terrace with edge face increases successively, on the axis that is centered close to described reflector of light source.
The Down lamp that the embodiment of the present invention provides comprises above-mentioned reflector and is located at the light source in above-mentioned reflector.
The illuminator that the embodiment of the present invention provides comprises above-mentioned Down lamp.
The Down lamp of below take is described in detail realization of the present invention as example.
As shown in Fig. 1～4, the Down lamp that the embodiment of the present invention provides comprises reflector 1 and is located at the light source 2 in reflector 1, on the axis that is centered close to reflector 1 of this light source 2.In the embodiment of the present invention, the inner surface of reflector 1 consists of multilayer terrace with edge face, and along the exit direction of light, the angle between adjacent two layers terrace with edge face increases successively.The light that light source 2 sends mixes in field of illumination after the reflection of multilayer terrace with edge face, uniform-illumination, and Luminaire efficiency is high.
The side that above-mentioned terrace with edge face is positive terrace with edge.The inner surface of reflector 1 consists of N layer terrace with edge face, 2≤N≤5; And the number that M has determined each layer of terrace with edge face is counted, 8≤M≤14 in the limit of the bottom surface of positive terrace with edge.Whole reflector 1 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 field of illumination, and uniform-illumination makes light soft.By regulating the angle between angle between adjacent layer terrace with edge face or each layer of terrace with edge face and reflector bottom surface, reach half required light intensity angle.
In the embodiment of the present invention, the inner surface of reflector 1 consists of two-layer terrace with edge face, and the limit number of the bottom surface of positive terrace with edge is 12, has 12 the first terrace with edge faces 11 and 12 the 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 α 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 adopts transparent Metal halogen lamp that power is 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, uniform-illumination in this light intensity angular region, meet the requirement to luminous intensity distribution fully.
Certainly, above-mentioned reflector 1 also can form Down lamps with dusting Metal halogen lamp, electricity-saving lamp, electrodeless florescent lamp etc.Correspondingly, the inner surface of reflector 1 consists of two-layer terrace with edge face, and the limit number of the bottom surface of positive terrace with edge is 10, has ten the first terrace with edge faces 11 and ten the second terrace with edge faces 12, as shown in Figure 6 and Figure 7.
For improving reflectivity, reflector 1 is made by high reflectance materials such as rafifinals.First adopt spinning block spinning during making, then form through the sizing die shaping, technique is simple, and cost is low.
The embodiment of the present invention is designed to multilayer terrace with edge face by the inner surface of reflector, direction along beam projecting, angle between adjacent two layers terrace with edge face increases successively, make on the axis that is centered close to reflector of light source, the light that light source sends mixes in field of illumination after the reflection of multilayer terrace with edge face, uniform-illumination, Luminaire efficiency is high.Adopt the lens Metal halogen lamp as light source simultaneously, make nearly 80 ° of the half light intensity corner connection of Down lamp, uniform-illumination in this light intensity angular region, meet the requirement to luminous intensity distribution fully.In addition, reflector first adopts spinning block spinning, then forms through the sizing die shaping, and technique is simple, and cost is low.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any modifications of doing within the spirit and principles in the present invention, be equal to and replace and improvement etc., within all should being included in protection scope of the present invention.
