Description
Technical field
The utility model belongs to lighting technical field, more particularly, to a kind of reflecting typed illuminating apparatus based on incandescent lamp.
Background technique
Since the luminous flux of light emitting diode and light efficiency are being continuously improved in recent years, application of the LED in each lighting area
More extensively.However, it is uniform that the intensity of illumination of LED is not able to satisfy hot spot in the range of 8 × 8mm in small-sized even optical illumination
Degree be not less than 95%, and the illumination of light intensity however less than the technical indicator of 8000 luxs.The light that incandescent lamp issues is closest to too
Sunlight has the characteristics that wide spectrum, luminous flux are big, power is high, but in irregular shape due to incandescent lamp filament, is difficult limited
Short distance forms Uniform Illumination.At present frequently with reflective cup type structure can make to a certain extent incandescent lamp be emitted light
Spot tends to uniformly, but its uniformity is unable to reach requirement, therefore designs suitable secondary light-distribution reflector for incandescent light source
It is particularly important.
Utility model content
To solve the problems, such as that the existing small-sized even optical illumination uniformity is not high, a kind of reflective photograph based on incandescent lamp is provided
Bright device, including supporting element, the incandescent lamp being mounted on supporting element and the reflector being arranged successively along optical propagation direction,
First off-axis reflecting surface, the second off-axis reflecting surface, light-emitting window；Reflector face shape is paraboloid, and the incandescent lamp is installed on
Reflector focal point；The light that incandescent lamp issues becomes directional light through reflector reflection, and directional light is successively spherical surface by face shape
The first off-axis reflecting surface and the second off-axis reflecting surface after from light-emitting window project.
Angle of the off-axis angle between the reflecting surface centre of sphere and the line and optical axis on its vertex.
Working principle: filament is in the focal point of parabolic mirror, and since filament is larger, light source deviates the coke of reflector
The light of point, outgoing only has part to collimate, and largely exhales, and first spherical reflector assembles diverging light, the
Converging light is carried out collimation outgoing again by two spherical reflectors, can achieve even results after multiple reflections.
Due to the application of the above technical scheme, the utility model realizes high-energy based on existing incandescent lamp, uniformly
Illumination.Compared with the uniform illumination device of transmission-type, the utility model is realized using the structure of two off-axis spherical reflective surfaces to be shone
The miniaturization of bright device, low-loss feature.
Detailed description of the invention
Fig. 1 is the schematic diagram of the section structure of lighting device；
Fig. 2 is the index path of lighting device；
Fig. 3 is the assembling schematic diagram of lighting device.
Specific embodiment
In order to illustrate more clearly of the utility model, it is further described with reference to the accompanying drawings and embodiments:
Embodiment one
A kind of reflecting typed illuminating apparatus based on incandescent lamp, as shown in Figure 1, including supporting element 6, being mounted on supporting element
Incandescent lamp 1 and the reflector 2 being arranged successively along optical propagation direction, the first off-axis reflecting surface 3, the second off-axis reflecting surface 4,
Light-emitting window 5；Reflector face shape is paraboloid；Assembling schematic diagram is as shown in figure 3, the incandescent lamp is installed on reflector focus
Place；The supporting element links into an integrated entity the reflector, the first off-axis reflecting surface, the second off-axis reflecting surface, light-emitting window；Light passes
The index path broadcast is as shown in Fig. 2, the light that incandescent lamp issues becomes directional light through reflector reflection, and directional light is successively by face first
It is projected after off-axis reflecting surface and the second off-axis reflecting surface from light-emitting window.
Embodiment two
On the basis of embodiment one, the paraboloid meets parabolic equation x=0.7846y2；
The spherical radius of the first off-axis reflecting surface is 15.477mm, and off-axis angle is -45 °；
The spherical radius of the second off-axis reflecting surface is 58.135mm, and off-axis angle is -45 °.
Embodiment three
On the basis of embodiment two, the incandescent lamp diameter is 3mm, and filament shape is inverted-triangular cylinder；It is described reflective
Rim of a cup 10mm, reflector rear surface described in the first off-axis reflecting surface vertex distance are 9mm, the second off-axis reflecting surface top
Point is 13mm apart from the first off-axis reflecting surface central point, and the lighting device light-emitting window diameter is 10mm.The lighting device
Total a height of 26.15mm, overall length 38mm.In this technical solution incandescent lamp can with parabolic mirror defocus 1mm, according to
LIGHTTOOLS software is emulated, the still available uniform light within the scope of lamp defocus 1mm；Off-axis spherical mirror is not total to the centre of sphere
And the centre of sphere deviates Y-axis 1mm, solves the problems, such as incandescent lamp illumination unevenness as caused by filament shape, realizes diameter 8mm model
Enclose the technical effect that the interior uniformity is not less than 95%.
