Description

The present invention relates to a lamp and particularly, but not exclusively, to a lamp for a road cone.
It is known to provide lamps upon road cones to alert drivers to the presence of road works and other potential road hazards, when driving at night or in conditions of reduced visibility.
Such lamps typically comprise a housing for housing bulbs or similar and a battery supply for providing power to the bulbs The lamps further comprise an exterior eyelet or similar bracket for securing the lamp to a road cone. However, since the lamps are battery powered, it is necessary to periodically check each lamp and if necessary re-charge the battery It will be appreciated that this is a time consuming exercise and is in addition to the time and labour involved in deploying and recovering the lamps.
I have now devised a lamp which alleviates the above-mentioned problems.
In accordance with the present invention there is provided an electrical lamp, the lamp comprising a housing, means for generating light housed substantially within said housing and an electrical power source for supplying electrical power to the means for generating light, the lamp further comprising means for supplying electrical power to said electrical power source.
The electrical power source preferably comprises at least one battery source housed within the housing, which can be re-charged using the means for supplying electrical power to the electrical power source.
Preferably, the means for supplying electrical power to the electrical power source comprises a solar panel.
The solar panel is preferably rotatably coupled to the housing and movable between a first configuration in which the solar panel substantially closes the housing and a second configuration in which the solar panel is arranged at an angle to the housing.
In the first configuration, the face of the solar panel preferably faces substantially into the housing, such that the rear of the solar panel acts to protect the face of the solar panel and the means for generating light.
The solar panel is preferably rotatably coupled to the housing at a position substantially along the periphery of the solar panel. The coupling preferably comprises a detent which holds the solar panel at a pre-defined angle in the second configuration.
Preferably, the angle is substantially 300 to the horizontal.
Preferably the coupling comprises a ball-and-socket type connection.
The lamp preferably further comprises means for securing the lamp to a road cone in an operative configuration and a stored configuration. In the operative configuration, the lamp extends substantially horizontally such that the light generated by the lamp is directed substantially toward oncoming vehicles and in the stored configuration the lamp extends substantially transverse to the first configuration.
Preferably, the means for securing the lamp to a road cone comprises an aperture extending through the housing and an eyelet which extends from the housing in a plane substantially transverse to the plane of the aperture.
The lamp preferably further comprises a first switch for enabling electrical power to be supplied to the means for generating light when in the operative configuration and a second switch for enabling electrical power to be supplied to the means for generating light when the level of light falls below a threshold value.
Preferably, the level of light is determined using light indication means, which may comprise a photodiode.
Preferably, the first and second switches must be ON in order to activate the means for generating light.
The lamp preferably further comprises battery indication means which determines the level of battery power remaining. The solar panel preferably re-charges the battery when the level of battery power remaining falls below a threshold power level The lamp preferably further comprises a compass for determining the direction in which the face of the solar panel is directed. Preferably, the face of the solar panel is arranged to point in a substantially southerly direction, when configured in the second configuration.
Preferably, the means for generating light comprises at least one bulb or light emitting diode or a combination thereof.
The preferred embodiment of the present invention wiii now be described by way of example only and with reference to the accompanying drawings in which: Figure 1 is a perspective view of the electrical lamp in accordance with the present invention with the solar panel in a first configuration; Figure 2 is a perspective view of the electrical lamp in accordance with the present invention with the solar panel in a second configuration; Figure 3 is a perspective view of the electrical lamp in accordance with the present invention, arranged in the operative configuration, with the solar panel in a second configuration; Figure 4 is a perspective view of the electrical lamp in accordance with the present invention, arranged in the stored configuration, with the solar panel in a second configuration; Figure 5 is a side view of the electrical lamp in the operative configuration with the solar panel in the second configuration, illustrating the angular orientation of the solar panel to the horizontal; and, Figure 6 is a magnified view of the compass of the electrical lamp.
Referring to the drawings, and initially figure 1 and 2 there is provided an electrical lamp 10 in accordance with the present invention for mounting to a road cone 11 or similar. The lamp 10 comprises a housing 12 for housing a battery supply (not shown) and lighting means (not shown), which may comprise a set of bulbs or light emitting diodes or a combination thereof, for generating light. The lighting means are held within the housing behind a transparent window 13 which may be coloured, for example yellow, to provide a distinctive colour to the light The housing 12 may be made of a rigid plastic material or metal, and comprises a rear section 12a, substantially square in cross-section, for housing the battery supply (not shown) and a front section 12b, substantially circular in cross-section, for housing the lighting means (not shown) The rear section 12a and front section 12b are separated by a neck portion 12c which comprises an aperture 14 that extends through the neck portion 12c and comprises internally tapered side walls which cooperate with the externally tapered side walls of the cone 11 The aperture 14 extends substantially transverse to the longitudinal axis of the lamp 10 and so by inserting the top of the cone 11 within the aperture 14, the lamp 10 extends substantially horizontally, as shown in figure 3. The lamp 10 further comprises an eyelet 15 which projects from the housing 12 and which extends in a plane substantially transverse to the plane of the aperture 14. The eyelet 15 permits the lamp 10 to be configured upon the cone 11 in a further configuration whereby the lamp 10 extends substantially vertically as shown infigure4.
The lamp 10 further comprises a solar panel 16 rotatably coupled to the periphery 17 of the front section 12b of the housing 12 at a position substantially along the periphery of the panel 16. The coupling 18 comprises a ball and socket type connection thereby permitting the solar panel 16 to pivot about three orthogonal axes. The panel 16 comprises a face section 16a and a protective rear panel 16b, both of which are substantially circular in cross-section and dimensioned to fit within the front section 12a of the housing 12. Accordingly, in a first configuration as shown in figure 1, the face 16a of the solar panel 16 is directed inwardly of the housing 12 such that the protective rear panel 16b faces outwardly and thus acts to protect the face 16a of the solar panel 16 and the lighting means (not shown).
The coupling enables the panel 16 to pivot from substantially within the housing 12, namely the first position, to a second position, as exemplified in figure 2, in which it extends at some angle to the lamp 10. This angle will depend upon whether the lamp 10 is in the operative or stored configuration but typically comprises an elevation of substantially 30° to the horizontal as illustrated in figure 5 This elevation of the panel 16 is enabled by the provision of a detent 19 which limits the movement of the panel 16 so that it can rest upon the detent 19 at the desired elevation In addition, the coupling 18 is provided with a compass 20 as shown in figure 6, so that the panel 16 can be rotated to face a southerly direction. This combination of elevation and azimuth is found to capture the maximum light from the sun and thus generate the maximum electrical power.
The lamp 10 further comprises a switch (not shown) positioned within the aperture 14 of the neck portion 12c and is arranged to switch ON when the lamp 10 is positioned atop the cone 11 in the operative configuration. However, the lighting means (not shown) is not activated until a further switch (not shown) is also switched ON. This further switch (not shown) is only switched ON when the levels of background light fall below a threshold value.
The level of background light is determined using light indication means (not shown) which may comprises a photodiode (not shown), which outputs a signal to the further switch (not shown) in dependence on the level of background light. Only when both switches are switched ON will the lighting means (not shown) illuminate.
In use the lamp 10 is placed upon a cone 11 by inserting the cone 11 through the aperture 14 until the internal walls of the aperture 14 abut the walls of the cone 11. The solar panel 16 may then be rotated from the first configuration so as to open the housing 12, to a second configuration in which the panel 16 extends at an elevation of substantially 300 and in a substantially southerly direction. During the night, or in conditions of diminished lighting, the lamp 10 will illuminate so as to alert drivers to potential road hazards. During the daytime, after periods of lamp use in which the battery levels have dropped, the solar panel 16 can then be used to re-charge the battery (not shown). However, to avoid over charging the battery, the lamp further comprises battery indication means (not shown) and a further switch (not shown) which only switches ON so as to re-charge the battery (not shown) when the battery power level has fallen below a threshold value When the lamp 10 is not required, it may be placed upon the cone 11 by inserting the top of the cone 11 through the eyelet 15, such that the lamp 10 is directed substantially vertically.
With the lamp 10 in the stored configuration, the solar panel 16 may be arranged in the first or second configuration, so as to close the housing 12 or provide for further charging, respectively.
From the foregoing therefore, it is evident that the lamp of the present invention provides for a simple yet effective means of powering road lamps. p
