Description
Technical field
The present invention relates to a kind of LED-based car light, especially relate to the car light that LED side is penetrated.
Background technology
LED have power consumptive province, life-span long, to many-sided advantages such as environment do not pollute, along with the continuous breakthrough of great power LED technology and declining to a great extent of cost, its application is more and more extensive, as the lamp source of automobile lamp, uses, because single LEDs power is less, need plurality of LEDs serial connection to use, in prior art, the illumination mode of LED is selected direct projection conventionally, and the luminous of plurality of LEDs seems attractive in appearance not, also more dazzling, visual effect is bad.
Summary of the invention
The present invention, according to above deficiency, provides a kind of car light of penetrating based on LED side.
Technical scheme of the present invention is:
A kind of car light of penetrating based on LED side, comprise: lamp bracket, circuit board and be arranged on the LED on circuit board, lamp bracket is also provided with main reflective surface and secondary reflective surface, the setting that is in the shape of the letter V of main reflective surface and secondary reflective surface, light entrance is left in the bottom of secondary reflective surface, circuit board is arranged on the outside of secondary reflective surface, and the light that LED sends is aimed at main reflective surface and irradiated, and main reflective surface and secondary reflective surface top are provided with light diffusion shell.
The arranging density of circuit onboard led, relevant with LED power.
Described smooth diffusion shell is inverted V font.The light that LED sends is aimed at main reflective surface irradiation rear portion light splitting and directly from side ejaculation, another part light of light diffusion shell, is penetrated again, thereby obtain good dispersion effect after secondary reflective surface reflection through another side of light diffusion shell.
For easy for installation, on the top lamp bracket of described main reflective surface and secondary reflective surface, be respectively arranged with re-entrant angle, light diffusion shell is stuck in this re-entrant angle.
As preferably, described main reflective surface is parabola or exponential type curved surface.
For reasonable distribution reverberation, another side is longer than in the side of the described smooth diffusion shell corresponding with described main reflective surface.Because main reflective surface is longer than secondary reflective surface, correspondingly, the side of the light diffusion shell corresponding with main reflective surface is longer.
As preferably, the included angle A of described main reflective surface starting point tangent line is 20-60 degree.
In order to improve reflectance luminous efficiency, on described main reflective surface, be provided with nanometer diffuse reflection coating.
On the top lamp bracket of described smooth diffusion shell, diffuser is installed, this diffuser is red conventionally.Under this scheme, described smooth diffusion shell is formed by injection molding by following raw material: transparent PC plastics are 100 weight portions, antioxidant: vapour bar 168 is that 0.30-0.7%, antioxidant vapour bar 1010 are 0.30-0.7%, lubricant is 0.6-1%, dispersant 0.4-0.8%, light diffusing agent: organosilicon is 1.5-2.5%, acrylate is 4-6%, fluorescent whitening agent KSN is 0.01-0.02%.
Described diffuser is covered on photodiffusion material and is made by red light transmissive material.Under this scheme, described photodiffusion material is formed by injection molding by following raw material: transparent PC plastics are 100 weight portions, antioxidant: vapour bar 168 is that 0.30-0.7%, antioxidant vapour bar 1010 are 0.30-0.7%, lubricant is 0.6-1%, dispersant 0.4-0.8%, light diffusing agent: organosilicon is 0.5-1%, acrylate is 1-2%, fluorescent whitening agent KSN is 0.01-0.02%.This technical scheme reduces ratio by light diffusing agent, to increase light transmittance.Certainly, all right, increase toner material, directly diffuser is made and had redness, there is light diffusion function simultaneously, can save so red light transmissive material as cover layer.By double scattering, can make light reach better dispersion effect.
The present invention has novel structure, cost is low, easy for installation, light transmittance is good, dispersion effect is obvious, the beneficial effect being evenly distributed of light.
