Abstract
The utility model discloses a lamp reflector, which comprises a lamp source device and a reflecting cover arranged above the lamp source device, wherein the inner side surface of the reflecting cover is in a recessed state, and is in a mirror surface shape which can reflect light, at least one convex mirror with the light diffusing function is arranged on the reflecting cover, and the convex mirror is arranged above the lamp source device, a part of light upwards projected of the light which is emitted by the lamp source device is downwards and outwards projected in bigger quadrant depressions after reflecting by the convex mirror, thereby expanding the projecting range of light. The reflecting cover of lamp has simple and reliable structure, which is convenient for industrialized production.
Description
Technical field
The utility model relates to field of light fittings, especially a kind of light fixture reflector.
Background technology
The lamp source of light fixture is generally spot light (HID xenon lamp, LED lamp), ball-type light source (osram lamp) and tubular light source (fluorescent lamp), and light fixture has certain projecting direction in light design, generally is set at downward projection more.Light source is when distributing light, and projection to all the winds for the light that will upwards throw forms downward projection to increase the exposure intensity of light source through reflection, just must be provided with reflector on light fixture.
Reflector on the light fixture that has can produce the optically focused effect, makes light concentrate projection, for example set reflector on the projecting lamp; Reflector on the light fixture that has can disperse light, and the scope that light is contained is bigger, for example set reflector on the lighting lamp.Generally light can be divided the reflector of scattered reflection, be the inclined-plane of several different gradients of utilization, the light that upwards throws is reflected into oblique light, and the light covering scope is enlarged, for example the reflector of fluorescent lamp; Use the light fixture of spot light, its set reflector mostly is sphere.The reflector of spherical can limit to the projection scope of light, makes the covering scope of light less.If the central authorities of this reflector are sphere, when connecting inclined-plane or plane cooperative programs around this sphere, though the scope that light is contained is bigger, can produce the perimeter lights luminous intensity and obviously be weaker than middle section, the uniformity of space illumination and harmonious degree are reduced.
Summary of the invention
In order to remedy above deficiency, the utility model provides a kind of light fixture reflector, can effectively enlarge the scope of the light-illuminating of light fixture, and after the range of exposures expansion, illumination uniformity can also be preferable.
The utility model for the technical scheme that solves its technical problem and adopt is:
A kind of light fixture reflector, comprise light source device and the reflector that is arranged on the light source device top, the medial surface of this reflector is the indent state, but the medial surface of described reflector is the mirror-like of reflection ray, described reflector is provided with the convex mirror of at least one tool astigmatism effect, this convex mirror is positioned at the top of described light source device, the part light that upwards throws in the light that this light source device sent is after this convex mirror reflection, can with the bigger angle of depression downwards, outwards projection, thereby enlarged the projection scope of light.
The Breadth Maximum of described convex mirror is greater than the width of described light source device.
Described convex mirror is strip.
Described convex mirror is dome shape.
Be laid with some marshallings and be the convex surface of dimpling shape around the described convex mirror.
The beneficial effects of the utility model are: because reflector is provided with the convex mirror of at least one tool astigmatism effect, and convex mirror is positioned at the top of described light source device, then the part light that upwards throws in the light that light source device sent is after this convex mirror reflection, can throw downwards with the bigger angle of depression, outside, thereby enlarged the projection scope of light, and after range of exposures enlarged, illumination uniformity can also be preferable.The utility model is simple in structure, reliable, is convenient to suitability for industrialized production.

The specific embodiment
Embodiment: a kind of light fixture reflector, comprise light source device 30 and the reflector 20 that is arranged on the light source device top, the medial surface of this reflector is the indent state, but the medial surface of described reflector is the mirror-like of reflection ray, described reflector 20 is provided with the convex mirror 21 of at least one tool astigmatism effect, this convex mirror is positioned at the top of described light source device 30, the part light that upwards throws in the light that this light source device 30 is sent is after these convex mirror 21 reflections, can with the bigger angle of depression downwards, outwards projection, thereby enlarged the projection scope of light.
The Breadth Maximum of described convex mirror 21 is greater than the width of described light source device 30.
Described convex mirror 21 is strip.
Described convex mirror 21 is dome shape.
Be laid with some marshallings and be the convex surface 22 of dimpling shape around the described convex mirror 21.
The utility model cooperation is used for light fixture: light fixture 1 comprises a casing device 10 and a diffuser 11; the diffuser casing device bottom that is connected; reflection shield 20 and light source device 30 are fixed positioned in the casing device 10; diffuser 11 is also allowed light penetration except the effect of guard lamp source apparatus 30 and reflector 20.The utility model cooperates the applicating example that is used for light fixture specific as follows:
Embodiment one: referring to Fig. 1, Fig. 2 and Fig. 3, the foregoing description is applied to road lamp, then described light source device 30 is HID (High IntensityDischarge Lamp) xenon lamp, is a kind of spot light; The convex mirror 21 of described reflector 20 is a strip, and respectively forms a cambered surface in the two sides of this convex mirror 21.This light source device 30 is the light of projection upwards, after the reflection of these convex mirror 21 two sides, can throw to both sides with the bigger angle of depression, and enlarge the scope of light fixture to the both sides projection, can reduce the dark band between two adjacent road lamps like this, to improve traffic safety and pedestrains safety.
Embodiment two: referring to Fig. 4 and Fig. 5, the convex mirror 21 of described reflector 20 is more than two and two, the light that light source device 30 is sent is after each convex mirror 21 reflection, and the outer ring light intensity that is projected is bigger, and makes the brightness in the whole space of being throwed more even.
Embodiment three: referring to Fig. 6, the convex mirror 21 of described reflector 20 is a dome shape, the light that light source device 30 is sent diffusion to all the winds after convex mirror 21 reflections, thus make the projection in space comparatively even.
The width of the convex mirror 21 described in the various embodiments described above is preferable with the width greater than described light source device 30, the light that is incident upon on the convex mirror 21 of light source device 30 is more like this, and light is also bigger through the angle of depression of reflection, thereby the projection scope of light significantly can be increased.
The medial surface of described reflector 20 is except being provided with described convex mirror 21, more can around convex mirror 21, lay some marshallings and be the convex surface 22 of dimpling shape, the light that light source device 30 upwards penetrates is done respectively to disperse projection after the reflection of each convex surface 22, and the light that light fixture is cast out is more even, soft.
