Illuminated apparatus closure

1. A closure for a housing of a sequencer apparatus, the housing including an opening through which access to an interior feature of the sequencer apparatus within the housing is provided, the closure comprising:

a frame configured for selective movement, along a single axis relative to the housing, to move the closure between a closed position in which access to the interior feature through the opening is blocked and an open position in which access to the interior feature through the opening is provided, wherein the selective movement includes movement of the closure between an inner wall of the sequencer apparatus and an outer wall of the sequencer apparatus, such that, in the open position, at least a portion of the closure is recessed between the inner wall and the outer wall;

a plurality of light sources supported by the frame and configured to emit light;

a reflector supported by the frame and configured to reflect the light emitted from the plurality of light sources;

a diffuser supported by the frame and configured to receive the reflected light and to diffuse the received reflected light (i) while the closure is translating the closure from a closed position to the open position, and (ii) when the closure is in the closed position; and

a controller configured to control the plurality of light sources, such that the diffused light indicates a status of an operational characteristic of the interior feature of the apparatus.

2. The closure of claim 1 , wherein the diffuser is supported on the frame relative to the reflector, such that an air gap exists between the diffuser and the reflector, the closure further comprising a lightguide positioned in the gap.

3. The closure of claim 2 , wherein the lightguide has a first primary surface opposite a second primary surface.

4. The closure of claim 3 , wherein the first primary surface is a first abraded surface.

5. The closure of claim 4 , wherein the second primary surface is a glossy surface.

6. The closure of claim 4 , wherein the second primary surface is a second abraded surface.

7. The closure of claim 3 , wherein the first primary surface is a light extraction surface.

8. The closure of claim 7 , wherein a separation between the light extraction surface and a front surface of the diffuser is selected so that the light distributed by the diffuser has a coefficient of variation less than about 9%.

9. The closure of claim 7 , wherein the plurality of light sources is arranged so that color gradients are blended across a length and a height of an illumination surface of the lightguide.

10. The closure of claim 3 , further comprising a first gradient of dot size extending between an edge of the first primary surface and a center of the first primary surface.

11. The closure of claim 10 , further comprising at least one second gradient of dot size oriented in a direction different from a direction of the first gradient of dot size.

12. The closure of claim 2 , wherein the plurality of light sources comprise light-emitting diodes (LEDs), and wherein at least two of the LEDs are mounted in a first row on a first side of a first circuit board.

13. The closure of claim 12 , wherein the LEDs comprise:

a first plurality of LEDs proximate to a first side of the lightguide, and

a second plurality of LEDs proximate to a second side of the lightguide opposite the first side, the second set of LEDs mounted in a second row on a first side of a second circuit board.

14. The closure of claim 13 , further comprising a first dowel pin extending from the frame and through the first circuit board and abutting the first side of the lightguide, and a second dowel pin extending from the frame and through the second circuit board and abutting the second side of the lightguide.

15. The closure of claim 2 , wherein each of the frame, the diffuser, and the lightguide has substantially a U-shape, and wherein the frame, the diffuser, and the lightguide are stacked with each other.

16. The closure of claim 1 , wherein the closure has substantially a U-shape.

17. The closure of claim 16 , wherein the closure substantially consists of a first portion, a second portion, and a third portion, the first portion connected and substantially perpendicular to the second portion, and the second portion connected and substantially perpendicular to the third portion.

18. The closure of claim 17 , wherein the second portion is configured to be positioned at a front of the sequencer apparatus, and wherein the first and third portions are configured to be positioned at respective sides of the sequencer apparatus opposite to each other.

19. The closure of claim 1 , wherein the interior feature of the sequencer apparatus is a sample receptacle for a sequencer for analysis of nucleic material of a sample.

20. The closure of claim 1 , further comprising:

a lift assembly comprising:

a motor; and

a lift mount coupled to the motor and to the closure and configured for translating the closure along the single axis.

21. The closure of claim 1 , wherein, in the closed position, the closure abuts a seal of the sequencer apparatus.
