Silicone LED Prescription Optics for Regulated Lighting Applications
A unitary silicone prescription optic has a molded silicone body comprising: a front surface configured as a light exit; an integral reflector configured to receive and reflect light from an LED light source; and an integral attachment portion configured to mount the molded silicone body within a housing. The unitary silicone prescription optic has many advantages over conventional optic systems.
1 . A unitary silicone prescription optic, comprising:
a molded silicone body, comprising:
a front surface configured as a light exit;
an integral reflector configured to receive and reflect light from an LED light source; and
an integral attachment portion configured to mount the molded silicone body within a housing.
2 . The unitary silicone prescription optic of claim 1 , wherein the prescription is for a vehicle exterior lamp.
3 . The unitary silicone prescription optic of claim 1 , wherein the front surface of the molded silicone body is a refractive face with a molded contour to produce a requisite light spread and light intensity.
4 . The unitary silicone prescription optic of claim 1 , wherein the front surface of the molded silicone body includes horizontal or vertical flutes or pillows.
5 . The unitary silicone prescription optic of claim 1 , wherein the reflector is a total internal reflector (TIR) providing greater than 55% efficiency of light collection and distribution.
6 . The unitary silicone prescription optic of claim 1 , wherein the reflector is a total internal reflector (TIR) providing greater than 75% efficiency of light collection and distribution.
7 . The unitary silicone prescription optic of claim 1 , wherein the reflector is a total internal reflector (TIR) providing 85% efficiency or greater of light collection and distribution.
8 . The unitary silicone optic of claim 1 , wherein the attachment portion is at a periphery of the molded silicone body.
9 . The unitary silicone optic of claim 8 , wherein the attachment portion comprises a reinforcing structure molded with the molded silicone body, the reinforcing structure imparting structural strength to the attachment portion.
10 . A prescription lamp, comprising:
a unitary molded body molded from silicone, comprising:
a front surface configured as a light exit;
an integral reflector molded to meet a prescription light output; and
an integral attachment portion;
an LED light source, the integral reflector receiving and reflecting light from the LED light source; and
a housing configured to mount the unitary molded body to a structure, the integral attachment portion attached directly to the housing without an additional seal member.
11 . The prescription lamp of claim 10 , wherein the structure is a vehicle and the prescription light output is for an exterior vehicle lamp.
12 . The prescription lamp of claim 10 , wherein the front surface of the unitary molded body is a refractive face with a molded contour to produce a requisite light spread and light intensity.
13 . The prescription lamp of claim 10 , wherein the front surface of the unitary molded body includes horizontal or vertical flutes or pillows.
14 . The prescription lamp of claim 10 , wherein the front surface is coating-free.
15 . The prescription lamp of claim 10 , wherein the integral reflector is a total internal reflector (TIR) providing greater than 55% efficiency of light collection and distribution.
16 . The prescription lamp of claim 10 , wherein the integral reflector is a total internal reflector (TIR) providing greater than 75% efficiency of light collection and distribution.
17 . The prescription lamp of claim 10 , wherein the integral reflector is a total internal reflector (TIR) providing 85% efficiency or greater of light collection and distribution.
18 . The prescription lamp of claim 10 , wherein the attachment portion is at a periphery of the unitary molded body.
19 . The prescription lamp of claim 18 , wherein the attachment portion comprises a reinforcing structure molded with the unitary molded body, the reinforcing structure imparting structural strength to the attachment portion.
20 . A lamp with a single-stage optic, the lamp comprising:
a unitary molded body molded from silicone, comprising:
a front surface configured as a light exit;
an integral reflector molded to meet a prescription light output; and
an integral attachment portion;
a light source; and
a housing configured to mount the unitary molded body to a structure.
