Abstract
The utility model provides an enhancement mode speculum assembly for projection unit, contains main reflector, main reflector constitutes with coupling part (3) by light source installation parts (1), reflecting part (2), coupling part (3) connection is at reflecting part (2) oral area, light source installation parts (1) is connected at reflecting part (2) afterbody, its characterized in that: reflecting part (2) and coupling part (3) on be equipped with one breach (4), have platform (5) on breach (4), fixed mounting is gone up in platform (5) has vice speculum (7). The utility model discloses, simple structure, simple to operate, supply through the luminance to distance light light beam, short -distance beam light beam of the vice speculum that increases, improved the efficient of light greatly.
Description
Technical field
This utility model is related to automobile lamp parts technical field and in particular to a kind of projecting unit enhancement mode reflects
Mirror assembly.
Background technology
The raising that development with automotive electronics and client require to automobile appearance, motor vehicles illumination regulation is to vehicle front lighting
The light shape of lamp is put forward higher requirement.The design content considering required for automobile lamp manufacturing industry becomes more, difficulty
Become big.Existing headlamp is in driving at night, no matter using road function or low-beam function, all there is the light of offer
Insufficient problem；It is primarily due to the design limitation of reflecting mirror, lead to substantial amounts of light cannot be utilized.Road function carries
For light beam weaker with the brightness of 1125R in order to meet the requirement of HV point brightness value, relative test point 1125L, lead to drive
Member is less in night vision scope, and safety is relatively low；Brightness on test point 75R, 50R, 50V for the light beam that low-beam function provides
Weaker, lead to driver less in night vision scope, safety is relatively low.
Content of the invention
For disadvantage mentioned above, this utility model purpose is to provide a kind of projecting unit enhancement mode to reflect mirror assembly, secondary
Reflecting mirror is spacing to be fixed on principal reflection mirror, by subreflector, the brightness of driving beam and passing beam is supplemented, greatly
Improve greatly the effective percentage of light.
The technical scheme of this utility model technology is achieved in the following ways：A kind of projecting unit enhancement mode reflects
Mirror assembly, comprises principal reflection mirror, and described principal reflection mirror is divided by light resource installing section, reflecting part and coupling part form, and connects
Part is connected to reflecting part oral area, and light resource installing section is divided and is connected to reflecting part afterbody；It is characterized in that：Described reflecting part
Divide and coupling part is provided with a breach, platform is had on breach, platform is installed with subreflector.
Described platform is provided with hole post and positioning table.
Described subreflector is provided with mounting plane corresponding with platform, and is provided with the lockhole of cooperation in the plane and determines
Position groove.
Described subreflector is provided with reflecting surface.
Described reflecting surface is the paraboloid of revolution or free form surface.
This utility model, structure is simple, easy for installation；By increased subreflector to driving beam, passing beam
Brightness is supplemented, and substantially increases the effective percentage of light.
Brief description
Fig. 1 is three-dimensional structure diagram of the present utility model.
Fig. 2 is the Structure explosion diagram of Fig. 1.
Fig. 3 is the A-A cut away view of Fig. 1.
Fig. 4 is that the light that Fig. 3 subreflector provides moves towards schematic diagram.
In figure：1 light resource installing section is divided, 2 reflecting parts, 3 coupling parts, 4 breach, 5 platforms, 6 subreflectors.
Specific embodiment
Known by Fig. 1, Fig. 2, Fig. 3, Fig. 4, a kind of projecting unit enhancement mode reflects mirror assembly, comprises principal reflection mirror, described
Principal reflection mirror divide 1, reflecting part 2 to form with coupling part 3 by light resource installing section, coupling part 3 is connected to 2 mouthfuls of reflecting part
Portion, light resource installing section divides 1 to be connected to reflecting part 2 afterbody；Described reflecting part 2 and coupling part 3 are provided with a breach
4, platform 5 is had on breach 4, platform 5 is installed with subreflector 6；Described platform 5 is provided with hole post 51 and positioning table
52；Described subreflector 6 is provided with mounting plane 61 corresponding with platform 5, and is provided with the lockhole 62 of cooperation in plane 61
And locating slot 63.Described subreflector 6 is provided with reflecting surface 64；Described reflecting surface 64 is the paraboloid of revolution or freely bent
Face.Subreflector 6 is passed through positioning table 52 and is positioned with locating slot 63 cooperation, carries out locking by screw afterwards and completes to be fixed on master
On the platform 5 of reflecting mirror, by subreflector 6, the light that the light that light source sends is reflected with principal reflection mirror is reflected, greatly
Improve greatly the effective percentage of light, complete the brightness of driving beam test point 1125L and 1125R is supplemented；Or to dipped beam
Brightness on test light beam point 75R, 50R, 50V is supplemented so that driver is big in night vision scope, and safety carries significantly
High.
