Description
Technical field
The invention belongs to lighting technical field, relate to a kind of lamp, particularly a kind of steering indicating light.
Background technology
Patent CN102147090A discloses a kind of lamps apparatus for vehicle, and single substrate arranges multiple LED light source, utilizes few, the low-cost structure of parts number, the scope that the vehicle periphery that throws light on brightly is wide.In side marker light, multiple LED light source is arranged on general substrate.The orientation of light source is formed with light guiding lens longly, utilizes screw to be arranged on lamp body by installation sheet, substrate erection be locked on the erection locking pin of light guiding lens and set up in engagement pawl.Light guiding lens is formed and the incident section of light source equal number and reflecting surface, vertical incident light is carried out horizontal reflection, the outgoing around door mirror from the transmittance section of outer cover.The difference towards the position according to LED light source of reflecting surface, the reflecting surface away from car body is got over towards rear view of vehicle.
The multiple LED light source of above-mentioned light fixture is arranged on substrate, will install LED light source one by one, installs trouble; Adopt screw fixed installation sheet, operation is many, and efficiency is low; LED corresponding light source, adjustment trouble, reflective surface is few, reflects even not.
Summary of the invention
The object of the invention is to there are the problems referred to above for existing technology, propose a kind of easy for installation, reflective function good, the steering indicating light of long service life.
Object of the present invention realizes by following technical proposal: a kind of steering indicating light, comprise back cover, the luminescence component fixing the transparent protecgulum on back cover and be arranged in back cover and protecgulum, it is characterized in that, described luminescence component comprises light-strip, spot light and LED, on described back cover, button is provided with Reflective seat, described Reflective seat protrudes formation one mount pad, described light-strip is arranged on mount pad, one end of described light-strip is provided with bending part and bending part is inserted in mount pad, chamfering is offered in the outside of the intersection of light-strip, described spot light to be arranged in mount pad and spot light just to the end at light-strip, the Reflective seat of mount pad both sides is distributed with several concave mirrors and the minute surface of concave mirror towards light-strip, several loopholes are offered in mount pad both sides, in described mount pad, LED board is installed, several LED are arranged on LED board, described LED is positioned at loophole and setting corresponding with concave mirror, wherein, described light-strip is made up of composite, described composite is become to be grouped into by following parts by weight: polymethyl methacrylate: 30-70 part, acrylonitrile-butadiene-styrene copolymer: 15-30 part, surface organic modification nano silicon: 1-3 part, ultra tiny alundum (Al2O3) particle: 5-10 part, glass fibre: 5-10 part, compatilizer: 5-10 part, fire retardant: 3-5 part, ultra-violet absorber: 1-3 part, antioxidant: 1-3 part.
The composite that in steering indicating light of the present invention, light-strip is used adopts transparency excellent, there is outstanding insulating properties, mechanical strength, corrosion-resistant, the polymethyl methacrylate (PMMA) of resistance to ag(e)ing, and there is better combination property as high-impact, the acrylonitrile-butadiene-styrene copolymer (ABS) of high-fire resistance is as complex matrix, then the surface organic modification nano silicon and the ultra tiny alundum (Al2O3) particle that add certain number do modification, by the synergy between its each composition, improve the combination property of composite, the remarkable surface smoothness improving composite, improve the hot strength of composite, heat resistance, 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 wherein the content of MMA is 98-100wt%, and 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.Nano silicon is and important inorganic nano material, and its particle diameter is little, and specific area is large, after organic modification of surface, add 1-3 part in composite, effectively can improve the performance of polymeric material in composite, as wearability, impact resistance etc., affect the transparency simultaneously.But only add a small amount of nano silicon and be also not enough to improve the hot strength of composite, other performances such as anticorrosive.And traditional toughening material is always based on organic elastomer, this kind of material to raising impact strength successful, but can make the correlated performances such as hot strength decline simultaneously.The composite of light-strip of the present invention uses the ultra tiny alundum (Al2O3) particle of inorganic rigid material not only to have toughening effect, can also improve the performances such as hot strength simultaneously.
