## Abstract

The present disclosure relates to the field of lighting systems. The collective dissipation of heat by various components of lighting systems, inside a conventional single compartment enclosure, raises the temperature of each of the components, resulting in damage and reduction in the life of the components. The present disclosure, therefore, envisages an enclosure for lighting systems which is compartmentalized, and prevents overheating of the components of the lighting systems. The enclosure includes a first compartment and a second compartment. At least one driver is receivable in the first compartment and at least one light emitting component is receivable in the second compartment. The first compartment is insulated from the second compartment. The enclosure is primarily used for lighting fixtures which require high efficiency operation from a compact package, or lighting fixtures which operate in rugged environments at high temperatures.

## Claims

### Claim 1

An enclosure for lighting systems, said enclosure comprising:
i. a first compartment provided in a first housing;
ii. at least one driver receivable in said first compartment and configured to generate a plurality of driving signals;
iii. a second compartment provided in a second housing; and
iv. at least one light emitting component receivable in said second compartment and configured to receive said plurality of driving signals;
wherein, said first housing is removably secured to said second housing; and said first compartment is insulated from said second compartment; and
wherein a first gasket is positioned between the first housing and the second housing providing a seal between the first housing and the second housing and adapted to provide a thermal break between said at least one driver in the first compartment of the first housing and said at least one light emitting component positioned in the second compartment of the second housing.

### Claim 2 (depends on 1)

The enclosure as claimed in claim 1, wherein a wall is provided in between said first housing and said second housing, and said wall is adapted to reduce transfer of heat between said first compartment and said second compartment.

### Claim 3 (depends on 2)

The enclosure as claimed in claim 2, wherein the relative optimum thickness of said wall ranges from 10 mm to 16 mm.

### Claim 4 (depends on 1)

The enclosure as claimed in claim 1, which includes a second gasket disposed in said second housing and adapted to provide a thermal insulation to said at least one light emitting component.

### Claim 5 (depends on 4)

The enclosure as claimed in claim 4, wherein said first gasket and said second gasket are made of silicone based rubber or low thermally conductive rubber or combinations thereof.

### Claim 6 (depends on 4)

The enclosure as claimed in claim 4, further including a third compartment positioned in the first housing, wherein a third gasket is positioned between the third compartment of the first housing and a third compartment cover providing a seal between the third compartment and the third compartment cover.

### Claim 7 (depends on 1)

The enclosure as claimed in claim 1, wherein a first plurality of fins are configured on said first housing, characterized in that
said first housing is configured to absorb excess heat generated by said at least one driver and dissipate the excess heat by means of said first plurality of fins.

### Claim 8 (depends on 7)

The enclosure as claimed in claim 7, wherein said first housing, said second housing, said first plurality of fins, and said second plurality of fins are made of a material selected from the group consisting of extruded Aluminum, high-density pressure die-cast material, cold forged Aluminum, Aluminum alloys with less than 0.4% Copper, and combinations thereof.

### Claim 9 (depends on 1)

The enclosure as claimed in claim 1, wherein said second compartment includes
a heat sink provided with a second plurality of fins, characterized in that said heat sink is configured to absorb excess heat generated by said at least one light emitting component and dissipate the excess heat by means of said second plurality of fins.

### Claim 10 (depends on 9)

The enclosure as claimed in claim 9, wherein said first housing, said second housing, said first plurality of fins, and said second plurality of fins are made of a material selected from the group consisting of extruded Aluminum, high-density pressure die-cast material, cold forged Aluminum, Aluminum alloys with less than 0.4% Copper, and combinations thereof.

### Claim 11 (depends on 1)

The enclosure as claimed in claim 1, which includes two drivers received on either operative end of said first compartment characterized in that said two drivers are disposed in said first compartment in an axially spaced apart configuration.

### Claim 12 (depends on 11)

The enclosure as claimed in claim 11, wherein each of said first plurality of fins provided on either of the axially opposite sides of said first housing, proximal to said two drivers disposed in said first compartment, has a profile which facilitates dissipation of the excess heat generated by each of said two drivers.

### Claim 13 (depends on 12)

The enclosure as claimed in claim 12, wherein said profile of each of said first plurality of fins, provided on either of the axially opposite sides of said first housing, includes a raised portion configured on an operative free end of each fin.

### Claim 14

An enclosure for lighting systems, said enclosure comprising:
i. a first compartment provided in a first housing;
ii. at least one driver receivable in said first compartment and configured to generate a plurality of driving signals;
iii. a second compartment provided in a second housing; and
iv. at least one light emitting component receivable in said second compartment and configured to receive said plurality of driving signals;
wherein, said first housing is removably secured to said second housing; and said first compartment is insulated from said second compartment; and further including
v. a third compartment provided in said first housing; and
vi. a plurality of wires receivable in said third compartment, and connected to said at least one driver and said at least one light emitting component;
wherein said plurality of wires are configured to carry said plurality of driving signals from said at least one driver to said at least one light emitting component.
