Description

Wearable Illumination Device

Introduction

The present invention relates to an illumination device and in particular a wearable illumination device for use by a person engaged in an activity when ambient light levels are low. Activities include, but are not limited to running or other outdoor exercise and those working in low light/night conditions.

Background to the Invention

Outdoor exercise activities are undertaken by many people including professional athletes and sports persons when in training for their sports and by others across a wide range of sports and ability levels. One of the main benefits of an outdoor exercise activity such as, walking jogging or running is that it can be done with little preparation or equipment and in all weathers.

One issue that confronts a person who is taking exercise is whether there is a suitable level of light for them to safely engage in their activity. In the case of sports such as football, rugby or the like, these activities are mainly done when there is sufficient daylight or under floodlights.

In many cases runners and walkers will exercise in public places such as streets, country roads and parks during daylight hours. Running and walking in the evening or at night when natural light levels diminish can be problematic. A primary concern is that if the person cannot properly see where they are going, they risk injury and cannot proceed safely with their exercise. A number of illumination devices have been proposed in order to assist with this problem.

Firstly, a person may simply carry a torch during exercising in conditions of insufficient daylight. However, holding a torch to light the way in front requires the person to alter their running style so as to maintain their arm in a fixed position to provide steady illumination of the path ahead.

Clip-on torches are available which a user can attach to an item of clothing. However, these devices only illuminate a small localised area in front and are difficult to attach to clothing and may fall off easily during exercise.

Head torches have been created specifically for the running and outdoor exercise market. These torches comprise a band which fits around and over the user’s head with the torch attached to the front of the band. However, it has been found that the torch only illuminates a small localized area in front of the wearer and that they are uncomfortable and prone to slip off and/or move. In addition, the illuminated area changes when the user moves their head.

The Gomotion litebelt ™ provides a belt with low power lights which allow the wearer to be seen and a clip on torch that illuminates a portion of the area in front of the wearer. It has the function of a clip on belt torch and a visibility belt combined.

Summary of the Invention

It is an object of the present invention to provide a device that improves the level and quality of illumination for a person engaged in exercise or other activity where the levels of natural light cause a significant reduction in visibility.

Detailed Description of the Drawings

The present invention provides an illumination device which allows a person to more safely exercise outdoors. Embodiments of the invention described herein show a loop suitable for wearing around a person’s waist upon which is mounted a source of illumination which lights the area in their immediate vicinity near their feet and in the area immediately in front of the wearer. Embodiments of the present invention also provide illumination to the rear and side of the wearer. It is advantageous to provide light across a wider area and to the periphery of where the person is moving. In addition, light at the side and rear may assist in lighting the path of others who may be running with the wearer.

Advantageously, by creating a device that is wearable around a person’s waist that provides light around the wearer, the wearer does not have to hold or direct the beam of light. In addition, positioning the light source at waist level reduces the glare that is often experienced by a user of a head torch.

Figure 1 is a perspective view of a first embodiment of an illumination device in accordance with the present invention. It shows an illumination device which comprises a closed loop 1 with a flat front surface 5 upon which an illumination source is arranged. The loop 1 is designed to fit around the waist of the wearer and may be made from fabric, leather or other suitable material. In this example, illumination is provided by a series of point sources of light which are substantially evenly spaced around the circumference of the loop 1 so as to create a substantially continuous lit area around the wearer which allows them to see the area around them. The lit zone is frusto- conical in its general geometry. In this embodiment of the invention, the loop is closed and the material from which it has been made is elasticated to securely fit the loop around the wearer’s waist.
