A plurality of light emitting diodes are used as the light source of the illuminating lamp, the pulse frequency of the light emitting diode ranges from 50 to 200Hz, and the duty ratio of the light emitting diode is not larger than 50 percent. The utility model has the advantages of energy conservation, environmental protection, long service life and good color developing performance, and provides convenience for the shooting of the monitoring devices.
Description
Technical field
The utility model relates to a kind of lighting device, and is particularly related to a kind of illuminating lamp that is used for bicycle lane and pavement monitoring.
Background technology
Along with increasing of Chinese vehicle, to the monitoring of the vehicle particular importance that seems, present electronic monitoring equipment each traffic main artery, each city that almost spreads all over the country, wherein electronic police is indispensable in transportation industry, and the lighting of auxiliary electron police monitoring also is varied, it wherein all is lighting at car lane, mostly be flash lamp or Metal halogen lamp, effect all is to provide light filling for the monitoring of giving car lane, wherein flash lamp was lighted in the moment of signal triggering, provide shooting required brightness to watch-dog, though shooting effect is good, but often moment brightness is excessive, the driver is easy to generate dazzle, cause the short-term discomfort of eye, the Metal halogen lamp light filling adopts the mode that continues illumination, at every moment can both reach and take required brightness, nor can produce uncomfortable to driver's eyes, it is low that but maximum shortcoming is exactly the effective rate of utilization of light, need be in illumination condition always, waste energy, in addition, the response speed of flash lamp and Metal halogen lamp is all slow, can't be applied to the monitoring system based on pulse mode.
The utility model content
In order to overcome in the prior art the excessive and low problem of effective rate of utilization light of illuminating lamp moment brightness, the utility model provides that a kind of brightness is suitable, the illuminating lamp of energy-conserving and environment-protective.
To achieve these goals, the utility model proposes a kind of illuminating lamp that is used for bicycle lane and pavement monitoring, the light source of described illuminating lamp is a plurality of light emitting diodes, and the pulse frequency of described light emitting diode is 50 to 200 hertz, and the dutycycle of described light emitting diode is not more than 50%.
Optionally, described dutycycle is 1: N, wherein N is greater than 1 and less than 31 natural number.
Optionally, described light emitting diode is positioned on the aluminium base.
Optionally, described aluminium base links to each other with heat dissipation base, fixes a plurality of fin on the described heat dissipation base.
Optionally, described illumination comprises supply unit, and described supply unit is by coupled power panel control.
A kind of beneficial effect that is used for the illuminating lamp of bicycle lane and pavement monitoring described in the utility model mainly shows: adopt light emitting diode as light-emitting device, launch cold white light, the colour temperature gentleness, not dazzling, and colour rendering is good, is easy to the shooting of supervising device; The pulse frequency of light emitting diode adopts 50 to 200 hertz, and pulse frequency height, human eye are difficult to discover the color transformed of light emitting diode; The dutycycle of light emitting diode is 1: N, wherein N is greater than 1 and less than 31 natural number, mean flow rate is the 1/N of peak brightness, can set the numerical value of N according to the road actual needs, be beneficial to energy savings.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the profile of the utility model embodiment.
The specific embodiment
The utility model will be further described below in conjunction with embodiment and accompanying drawing.
In background technology, the brightness of mentioning flash lamp moment is bright excessively, causes drivers's eyes to be shaken easily, and Metal halogen lamp needs continual opening, and wastes energy, and novel proposition of this use replaces flash lamp and Metal halogen lamp with light emitting diode (LED).
Please refer to Fig. 1, Fig. 1 is the structural representation of the utility model embodiment, on scheming, can see that a plurality of fin 2 are placed between the heat dissipation base 1, lampshade 5 is fixed on the heat dissipation base 1 by nut, heat dissipation base 1 links to each other with a support 4 by a support zone 3, the outward appearance of whole device is succinctly practical, easily uses on bicycle lane and pavement.
LED has the luminous efficiency height, advantages such as power saving and life-span are long, but single LED luminous quantity is limited, can not satisfy daily lighting demand, need be with the densely arranged integrated together use of a plurality of LED, this can cause heat to accumulate in a large number in the less space and can not distribute rapidly, when LED works under the very high environment of temperature, will wear out rapidly, make its life-span shorten greatly, please refer to Fig. 2 below, Fig. 2 is the profile of the utility model embodiment, the utility model all is positioned over a plurality of LED 22 on the aluminium base 6, and described aluminium base 6 links to each other with heat dissipation base 1, fixes a plurality of fin 2 on the described heat dissipation base, such design has guaranteed that the utility model heat sinking function is good, the LED back local temperature too high problem that works long hours can not occur.In addition, the pulse frequency of the light emitting diode that the utility model adopts is 50 to 200 hertz, and pulse frequency height, human eye are difficult to discover the color transformed of light emitting diode; The dutycycle of light emitting diode is 1: N, wherein N is greater than 1 and less than 31 natural number, dutycycle is the ratio in positive pulse width and cycle, popular saying is exactly in an illumination period, the ratio of time that LED opens and cycle time, dutycycle is low more, the energy that illumination is digested is just more little, the mean flow rate that illuminating lamp provided is just low more, mean flow rate is the 1/N of peak brightness, can set the numerical value of N according to the road actual needs, be beneficial to energy savings, and can not make pedestrian's vision produce strong light stimulus.As can see from Figure 2, the utility model also comprises a supply unit 8 and the power panel 9 that is positioned over the one side, the external exit of supply unit 8 and the power supply of outside 220V are connected, the voltage of internal access port input 55V is given power panel 9, power panel 9 connects supply unit 8 and a plurality of LED 22, power panel 9 is controlled the opening and closing of LED 22, thereby realizes the pulse frequency and the dutycycle of predefined light emitting diode.
Though the utility model discloses as above with preferred embodiment, so it is not in order to limit the utility model.Have in the technical field under the utility model and know the knowledgeable usually, in not breaking away from spirit and scope of the present utility model, when being used for a variety of modifications and variations.Therefore, protection domain of the present utility model is as the criterion when looking claims person of defining.
