Abstract

An LED vehicle light assembly providing a ring of diffuse light for taillight functions surrounding an area of non-diffuse light for stop and turn functions.

Claims

1. A vehicle light assembly comprising:

a base with a front and a back, where the base has a first recess surrounding a second recess;

an outer array of lights sized to fit within the first recess at a first level;

an inner array of lights sized to fit within the second recess at a second level, where the second level is closer to the front of the base than the first level;

a diffuser lens located at the front of the base, where the diffuser lens is sized and shaped to cover the outer array of lights but not the inner array of lights; and

a cover lens located at the front of the base covering the diffuser lens, the outer array of lights, and the inner array of lights.

2. The vehicle light assembly of claim 1 where lights on the outer array of lights and the lights on the inner array of lights are light emitting diodes.

3. The vehicle light assembly of claim 1 where the base, the second recess, the inner array of lights, and the cover lens are circular and where the first recess, the outer array of lights, and the diffuser lens are ring-shaped.

4. The vehicle light assembly of claim 1 where the base, the second recess, the inner array of lights, and the cover lens are oblong and where the first recess, the outer array of lights, and the diffuser lens are shaped like an oblong ring.

5. The vehicle light assembly of claim 1 further comprising one or more posts within the first recess such that the outer array of lights may rest against the posts to maintain position at the first level.

6. The vehicle light assembly of claim 5 further comprising one or more attachment devices attaching the outer array of lights to the one or more posts within the first recess.

7. The vehicle light assembly of claim 1 where the first level is located at an optimum distance from the diffuser lens, where the diffuser lens has a refractive index and the outer array of lights have a spread of light and where the optimum distance is determined by taking into consideration the refractive index of the diffuser lens and the spread of light from the outer array of lights to create a smooth, non-intrusive ring of light.

8. The vehicle light assembly of claim 1 further comprising one or more posts within the second recess such that the inner array of lights may rest against the posts to maintain position at the second level.

9. The vehicle light assembly of claim 8 further comprising one or more attachment devices attaching the inner array of lights to the one or more posts within the second recess.

10. The vehicle light assembly of claim 1 further comprising one or more electrical connectors in the back of the base and connected to the outer array of lights and the inner array of lights.

11. The vehicle light assembly of claim 1 where the diffuser lens is made of a first material and where the cover lens is made of a second material, where the first material diffuses light more than the second material.

12. The vehicle light assembly of claim 1 where the outer array of lights is connected to a vehicle such that the outer array of lights is constantly illuminated while the vehicle is in operation.

13. The vehicle light assembly of claim 12 where the outer array of lights is connected to the vehicle such that the outer array of lights increases in light output when a brake of the vehicle or a turn signal of the vehicle is engaged.

14. The vehicle light assembly of claim 1 where the inner array of lights is connected to a vehicle such that the inner array of lights is illuminated only when a brake of the vehicle or a turn signal of the vehicle is engaged.
