Description
Technical field
The invention belongs to lighting technical field, it is related to a kind of lamp, particularly a kind of steering indicating light.
Background technology
Patent CN102147090A discloses a kind of lamps apparatus for vehicle, arranges multiple LED light sources on single substrate, profit
With parts number is few, low-cost structure, the wide scope of illumination vehicle periphery brightly.In side marker light, many
Individual LED light source is arranged on general substrate.Light guiding lens are formed with the orientation of light source longly, will using screw
Installation sheet is arranged on lamp body, substrate is set up the erection locking pin being locked on light guiding lens and sets up in engagement pawl.In leaded light
Incident section with light source equal number and reflecting surface are formed with lens, vertical incident illumination are carried out horizontal reflection, from outer
Transmittance section outgoing to around door mirror of cover.The direction of reflecting surface is different according to the position of LED light source, is more remote from car
The reflecting surface of body is got over towards rear view of vehicle.
Above-mentioned light fixture is arranged on substrate with multiple LED light sources, will install LED light source one by one, installs trouble；Using spiral shell
Silk fixed installation piece, operation is many, and efficiency is low；LED corresponding light source, adjustment trouble, reflective surface is few, and reflection is not uniform.
Content of the invention
The purpose of the present invention is to there are the problems referred to above for existing technology it is proposed that a kind of easy for installation, reflective function
The good, steering indicating light of long service life.
The purpose of the present invention can be realized by following technical proposal：A kind of steering indicating light, including back cover, fixes on back cover
Transparent protecgulum and the luminescence component that is arranged in back cover and protecgulum it is characterised in that described luminescence component include light-strip,
Point source and LED, on described back cover, button is provided with Reflective seat, and described Reflective seat protrudes above formation one mounting seat, described light-strip
It is arranged in mounting seat, one end of described light-strip is provided with bending part and bending part is inserted in mounting seat, in the phase of light-strip
Outside at friendship offers chamfering, and described point source is arranged in mounting seat and point source is just to the end in light-strip, in peace
The minute surface of several concave mirrors and concave mirror is distributed with the Reflective seat of dress seat both sides towards light-strip, opens up in mounting seat both sides
There are several loopholes, in described mounting seat, LED board is installed, several LED are arranged on LED board, described LED is located at
Printing opacity in the hole and setting corresponding with concave mirror, wherein, described light-strip is made up of composite, and described composite is by following
Parts by weight become to be grouped into：Polymethyl methacrylate：30-70 part, acrylonitrile-butadiene-styrene copolymer：15-30 part,
Surface organic modification nano silicon：1-3 part, ultra tiny aluminium sesquioxide particle：5-10 part, glass fibre：5-10 part, phase
Hold agent：5-10 part, fire retardant：3-5 part, UV absorbent：1-3 part, antioxidant：1-3 part.
In steering indicating light of the present invention, the composite used by light-strip adopts transparency excellent, has prominent insulating properties, machinery
Intensity, corrosion-resistant, resistance to ag(e)ing polymethyl methacrylate (PMMA), and there is preferable combination property such as high-impact, height
As complex matrix, the surface then adding certain number has the acrylonitrile-butadiene-styrene copolymer (ABS) of thermostability
Machine modified manometer silicon dioxide and ultra tiny aluminium sesquioxide particle make modification, by the synergism between its each composition, carry
The combination property of high composite, significantly improves the surface smoothness of composite, improves the tensile strength of composite, heat-resisting
Performance, melt viscosity etc., and then improve the service life of light-strip.
In the composite, the mean molecule quantity of described polymethyl methacrylate is 5-25 ten thousand, and the wherein content of MMA is
98-100wt%, melt index is 5-11, and cantilever beam impact strength is 26-29J/m.
In the composite, the radius of described surface organic modification nano silicon is 20-100nm.Nanometer titanium dioxide
Silicon is and its important inorganic nano material that its particle diameter is little, and specific surface area is big, after organic modification of surface, adds 1-3 part and arrives
In composite, can effectively improve the performance of polymeric material in composite, such as wearability, impact resistance etc., shadow simultaneously
Ring the transparency.But only add a small amount of nano silicon be also not enough to improve composite tensile strength, anticorrosive etc. its
His performance.And traditional toughening material is always based on organic elastomer, this kind of material to improving impact strength effect substantially, but
But the correlated performances such as tensile strength can be made to decline simultaneously.The composite of light-strip of the present invention is with using inorganic rigid material ultra micro
Thin aluminium sesquioxide particle not only has toughening effect, can also improve the performances such as tensile strength simultaneously.

Impact strength improves 10 times about, and stretching is slight to improve 3 times about.Because inorganic particulate is evenly dispersed in matrix, work as base
When body receives impact, between particle and matrix, produce micro-crack, the matrix between particle also produces plastic deformation simultaneously, absorbs punching
Hit energy, thus reaching toughness reinforcing effect.Diminish with particle diameter, the specific surface area of particle increases, between particle and matrix
Contact surface increases, and material, when being impacted, can produce more micro-cracks and plastic deformation, thus absorbing more impact
Can, toughening effect improves.But when the addition of ultra tiny aluminium sesquioxide particle is excessive, get too close between particle, material is subject to
Produce micro-crack during impact and plastic deformation is excessive, almost develop into macro-stress cracking, make the impact property of material on the contrary
Decline.
Additionally, adding the glass fibre that 5-10 part radius is 3 μm -10 μm in composite of the present invention, both can serve as
Filler is it is also possible to significantly improve the mechanical property of composite, thermostability, ageing-resistant performance.
In the composite, described compatilizer includes chlorinated polyethylene (CPE), SMA styrene maleic anhydride copolymer (SMA), ring
Oxidative ethane-propylene oxide block copolymer.Add above-mentioned compatilizer in the composite of PMMA, ABS, composite can be improved
Notch impact strength, and improve ageing-resistant performance and the weld strength of composite, also can improve processing characteristics simultaneously.
