## Abstract

A lighting system utilizing light-emitting diodes (LEDs) and methods for configuring lanterns thereof are disclosed. The lantern includes a roof or canopy that includes fans that span directly between the electronics and LEDs for improved heat dissipation, the fans preferably formed integral with the canopy. The LEDs are mounted on easily mounted and removed modular printed circuit boards, in at least two different sizes and numbers of LEDs, and optical lenses of at least two different lighting patterns are provided, so that the lantern may be assembled or retrofit according to a desired application including candlepower and lighting pattern for cast light. The optical lenses are individually provided, utilize refraction to diminish reflection, and, in one form, incorporate an integral reflector to assist in defining a lighting pattern. In some forms, a securement may be provided for individual securement of lenses with the PCB.

## Claims

### Claim 1

A lighting device comprising:
a canopy including:
an outer surface externally exposed to atmosphere; and
a heat sink adapted to transfer heat to the atmosphere;
a base having a lighting element coupled thereto, the base coupled to the heat sink such that the heat sink obtains heat from the lighting element; and
a securement device adapted to couple to the base and retain a lens, the securement device including:
a ring having a center point, an outer circumference facing away from the center point, and an inner circumference facing toward the center point; and
a plurality of teeth extending radially inwardly from the inner circumference and adapted to retain the lens in the securement device.

### Claim 2 (depends on 1)

The lighting device of claim 1, further comprising a tab extending from the ring and coupling the ring to the base.

### Claim 3 (depends on 2)

The lighting device of claim 2, wherein the tab includes a leg and a foot, wherein the leg extends from the ring and the foot is adapted to be coupled to the base.

### Claim 4 (depends on 3)

The lighting device of claim 3, wherein the foot extends radially inward.

### Claim 5 (depends on 4)

The lighting device of claim 4, wherein the foot is soldered to the base.

### Claim 6 (depends on 3)

The lighting device of claim 3, wherein the foot is soldered to the base.

### Claim 7 (depends on 1)

The lighting device of claim 1, wherein the teeth are triangular shaped.

### Claim 8 (depends on 1)

The lighting device of claim 1, wherein the teeth are disposed seriatim along the ring.

### Claim 9 (depends on 1)

The lighting device of claim 1, wherein the lighting element is disposed substantially proximate the center point.

### Claim 10

An attachment comprising: a circuit board; a lighting element coupled to the circuit board; a securement device coupled to the circuit board, the securement device including:
a ring having a planar shape and having a center point, an outer circumference facing away from the center point, an inner circumference wherein the inner surface is disposed closer to the center point than the outer circumference, the ring having a top surface and a bottom surface opposite the top surface;
a tab coupled to the ring and coupled to the circuit board, the tab having a leg extending from the ring and a foot extending at an angle from the leg, the foot being coupled to the circuit board; and
a plurality of teeth extending radially inwardly from the inner circumference; and a lens retained by the teeth.

### Claim 11 (depends on 10)

The attachment of claim 10, wherein the foot extends radially inward.

### Claim 12 (depends on 10)

The attachment of claim 10, wherein the foot is soldered to the circuit board.

### Claim 13 (depends on 10)

The attachment of claim 10, wherein the teeth are triangular shaped.

### Claim 14 (depends on 10)

The attachment of claim 10, wherein the teeth are disposed seriatim along the ring.

### Claim 15 (depends on 10)

The attachment of claim 10, wherein the lighting element is disposed substantially proximate the center point.

### Claim 16 (depends on 10)

The attachment of claim 10, wherein the tab is soldered to the circuit board.
