Abstract

A trailer lamp assembly has a moulded shell 9 closed by a red and amber lid 3, 4. A pair of raised wells 28 sit beneath the red and amber parts of the lid and each contains a multiple LED array 32 waterproofed by a pool of resin 36. A compartment 15 in the shell between the wells contains a downwardly directed further LED array 25. The incoming electric leads 42 pass through a plug of hardened resin 44 and enter a distributor box 38 likewise waterproofed by a pool of hardened resin 48.

Claims

1. A rear lamp assembly provides a rear lamp assembly for a trailer comprising a housing shell with an open top and a continuous sidewall, a transparent red and amber lid closing the top, a pair of receptacles within the housing, a multiple LED array in each well, a current distribution box within the housing, a compartment within the housing lying between the receptacles and defining a downwardly directed window in the sidewall, an LED array in the compartment for illuminating an area beneath the housing, a transparent cover for the window, the housing defining an incoming electric cable aperture, multiple incoming conductor leads entering the aperture and connecting with the distribution box, conductor leads extending from the current distribution box to the LED arrays, a pool of hardened resin in each receptacle and in the distribution box which waterproofs the LED arrays and the distributor box.

2. A rear lamp assembly as claimed in claim 1, wherein the distribution box lies between the wells.

3. A rear lamp assembly as claimed in claim 2, wherein the distribution box contains a circuit board bearing electrical components, the board has connectors for the multiple conductor leads, the box at least partially defines a well which registers with the cable aperture, the leads pass through the well and the well contains a plug of hardened resin.

4. A rear lamp assembly as claimed in claim 1, wherein the compartment defines electrical lead apertures whereby conductor leads extending from the distribution box to the LED array in the compartment pass through the apertures which are sealed with gap sealant.

5. A rear lamp assembly as claimed in claim 1, wherein both receptacles contain a circuit board which mounts the LED array and the pool of resin immerses the circuit board but allows the LEDs to protrude.

6. A rear lamp assembly as claimed in claim 5, wherein the array comprises a regular cluster of 10-12 LEDs.

7. A rear lamp assembly as claimed in claim 5, wherein the receptacles are open-topped pans of lesser depth than the housing depth, each with a rim and are raised so that the rim is substantially level with the open top of the housing shell.

8. A rear lamp assembly as claimed in claim 7, wherein the pans are supported on the housing by stalks.

9. A rear lamp assembly as claimed in claim 1, wherein the compartment is elongated and accommodates a single row of LEDs.

10. A rear lamp assembly as claimed in claim 1, wherein the housing shell has downwardly facing drain holes in the sidewall beyond the compartment.
