Claims

A lighting module for a lighting device, the lighting module comprising:
at least one light source provided on the substrate;
an optical assembly positioned over the at least one light source;
A sensor including a transceiver configured to direct radiation toward said optical assembly and receive radiation reflected by said optical assembly, said reflected radiation indicating one or more states of said optical assembly. indicating a sensor ;
a processor;
When executed by the processor, causes the processor to:
receiving information from the sensor corresponding to radiation reflected by the optical assembly;
analyzing the received information to determine the presence of an obstruction or deformation on the optical assembly of at least a threshold level, the threshold level being the material of the optical assembly, the material of other components of the illumination module, or determined based on at least one of the efficiency of a heat sink associated with the lighting module; and
taking remedial action in response to determining the presence of at least a threshold level of obstruction or deformation on the optical assembly;
a non-transitory computer readable medium containing programming instructions to cause
lighting module.

2. The lighting module of claim 1, wherein the sensor is an infrared (IR) sensor and the transmitted radiation is IR radiation.

The recovery action includes providing an alert to the user, the alert comprising:
instructions for repairing said obstruction or said deformation;
instructions for controlling the power supplied to said at least one light source, or information about said obstacles or said deformations;
3. The lighting module of claim 1 , comprising at least one of:

The programming instructions for controlling power supplied to the at least one light source include instructions for reducing power supplied to the at least one light source while maintaining a constant lighting output by the lighting device. 4. A lighting module according to claim 3 .

2. The lighting module of Claim 1 , wherein the restoration action includes increasing power to other light sources .

The lighting module causes the processor to:
analyzing the received information to determine a percentage of the state of the optical assembly;
analyzing a rate of state change to determine if the lighting module contains a problem; and providing an alert to a user, the alert including information about the problem.
2. The lighting module of claim 1 , comprising programming instructions configured to cause:

The obstruction or deformation may be debris accumulation, dirt accumulation, water accumulation, moisture accumulation, color change, shape change, breakage, foreign matter accumulation, or pitting inside or outside the optical assembly. 2. The lighting module of claim 1 , comprising at least one of forming.

The illumination module instructs the processor to analyze the received information to identify the obstacle or deformation, the type of obstacle or deformation, the level of the obstacle or deformation, or the obstacle or deformation on the optical assembly. 2. The lighting module of claim 1 , comprising programming instructions that cause determining at least one of the positions of the .

2. The lighting module of Claim 1, wherein the at least one light source is a light emitting diode.

2. The lighting module of claim 1, wherein the sensor is provided on the substrate.
