Abstract

A sanitization apparatus of a vehicle includes (i) surfaces defining a chamber configured to accept an object to be sterilized with ultraviolet light and (ii) a first light emitting diode (LED) including a die that is configured to emit ultraviolet light. The die has a primary surface that defines a plane that extends through the chamber. The sanitization apparatus further includes a first reflective surface that is reflective of ultraviolet light disposed adjacent to the first LED. At least a portion of the ultraviolet light that the die emits reflects off of the first reflective surface and into the chamber. The first reflective surface defines a plane that intersects with the plane that the primary surface of the die defines.

First claim

What is claimed is:

1 . A sanitization apparatus comprising:
a first sanitization module and a second sanitization module facing the first sanitization module, both of the first sanitization module and the second sanitization module comprising:
a backplate comprising a perimeter and a reflective surface;
a housing comprising a wall with an inner surface that extends around the perimeter of the backplate, the wall of the housing comprising an upper portion and a lower portion that opposes the upper portion;
an upper plurality of LEDs disposed on the inner surface of the upper portion of the wall of the housing, each of the upper plurality of LEDs configured to emit ultraviolet light;
a lower plurality of LEDs disposed on the inner surface of the lower portion of the wall of the housing, each of the lower plurality of LEDs configured to emit ultraviolet light; and
a cover attached to the housing, the cover (i) substantially transparent to the ultraviolet light that the upper plurality of LEDs and the lower plurality of LEDs are configured to emit, (ii) together with the backplate and the housing, encapsulating the upper plurality of LEDs and the lower plurality of LEDs, and (iii) comprising a cover surface facing generally away from the reflective surface of the backplate,
wherein, the cover surface of the first sanitization module and the cover surface of the second sanitization module (i) oppose each other and (ii) together partially define a chamber to accept an object to be sanitized with the ultraviolet light that the upper plurality of LEDs and the lower plurality of LEDs are configured to emit, and wherein, the reflective surface of the backplate is substantially reflective of the ultraviolet light that the upper plurality of LEDs and the lower plurality of LEDs are configured to emit.

2 . The sanitization apparatus of claim 1 , wherein
for both the first sanitization module and the second sanitization module, each of the upper plurality of LEDs and each of the lower plurality of LEDs comprises a die that (i) is configured to emit the ultraviolet light, at least a portion of which reflects off of the reflective surface of the backplate, through the cover, and into the chamber and (ii) comprises a primary surface that defines a plane that extends into the chamber.

3 . The sanitization apparatus of claim 2 , wherein
for both the first sanitization module and the second sanitization module, the reflective surface of the backplate defines a plane that intersects with the planes that the primary surfaces of the dies of the upper plurality of LEDs and the lower plurality of LEDs define.

4 . The sanitization apparatus of claim 3 , wherein
for both the first sanitization module and the second sanitization module, the plane that the reflective surface of the backplate defines is substantially perpendicular to the planes that the primary surfaces of the dies of the upper plurality of LEDs and the lower plurality of LEDs define.

5 . The sanitization apparatus of claim 1 further comprising:
a floor that provides a surface that at least partially defines the chamber, along with the cover surface of the first sanitization module and the cover surface of the second sanitization module, the floor configured to support the object to be sterilized from below the object;
wherein, the lower plurality of LEDs of both of the first sanitization module and the second sanitization modules is disposed elevationally above the floor.

6 . The sanitization apparatus of claim 5 further comprising:
opposing side walls extending upward from the floor, each of the opposing side walls comprising a surface that further defines the chamber.

7 . The sanitization apparatus of claim 1 further comprising:
a lid that provides selective access to the chamber, the lid movable to, from, and between (i) an open position where the lid allows access into the chamber and (ii) a closed position where the lid denies access into the chamber.

8 . The sanitization apparatus of claim 7 further comprising:
a lock engageable with the lid to prevent the lid from moving away from the closed position to the open position.

9 . The sanitization apparatus of claim 2 , wherein, for both the first sanitization module and the second sanitization module,
each of the primary surfaces of the dies of the first upper plurality of LEDs shares a plane substantially in common; each of the primary surfaces of the dies of the first lower plurality of LEDs shares a plane substantially in common; each of the primary surfaces of the dies of the second upper plurality of LEDs shares a plane substantially in common; and each of the primary surfaces of the dies of the second lower plurality of LEDs shares a plane substantially in common.

10 . The sanitization apparatus of claim 1 , wherein for both the first sanitization module and the second sanitization module,
each LED of the first lower plurality of LEDs faces one of the LEDs of the first upper plurality of LEDs; and each LED of the second lower plurality of LEDs faces one of the LEDs of the second upper plurality of LEDs.

11 . The sanitization apparatus of claim 1 , wherein, for both the first sanitization module and the second sanitization module,
the reflective surface of the backplate is oriented to form an angle of 10 degrees or less from vertical.

12 . A vehicle comprising:
an interior; a body that separates the interior from an environment external to the vehicle; and the sanitization apparatus of claim 1 disposed within the interior.

13 . The vehicle of claim 12 further comprising:
a center console disposed within the interior, the center console comprising the sanitization apparatus.

14 . The vehicle of claim 12 further comprising:
a seating assembly disposed within the interior and disposed adjacent the sanitization apparatus.

15 . The vehicle of claim 12 further comprising:
an armrest disposed within the interior,
wherein, the sanitization apparatus is disposed under the armrest.

16 . The vehicle of claim 12 , wherein
for both the first sanitization module and the second sanitization module, each of the upper plurality of LEDs and each of the lower plurality of LEDs comprises a die that (i) is configured to emit the ultraviolet light, at least a portion of which reflects off of the reflective surface of the backplate, through the cover, and into the chamber and (ii) comprises a primary surface that defines a plane that extends into the chamber.

17 . The vehicle of claim 12 further comprising:
a floor that provides a surface that at least partially defines the chamber, along with the cover surface of the first sanitization module and the cover surface of the second sanitization module, the floor configured to support the object to be sterilized from below the object;
wherein, the lower pluralities of LEDs of both of the first sanitization module and the second sanitization modules are disposed elevationally above the floor.

18 . The vehicle of claim 17 further comprising:
opposing side walls extending upward from the floor, each of the opposing side walls comprising a surface that further defines the chamber.

19 . The vehicle of claim 12 further comprising:
a lid that provides selective access to the chamber, the lid movable to, from, and between (i) an open position where the lid allows access into the chamber and (ii) a closed position where the lid denies access into the chamber.

20 . A vehicle comprising:
