Definitions

  • the present invention relates to a street lamp, and relates more particularly to an LED (light emitting diode) street lamp having an auxiliary lamp.
  • An LED lamp can reduce electrical energy consumption by 40 percent compared to a conventional incandescent lamp having the same brightness.
  • many countries have energy-saving policies to introduce LED devices into various lighting fields.
  • the LED street lamps Compared with conventional street lamps such as metal halide lamps, incandescent lamps, and high pressure sodium lamps, the LED street lamps not only save energy but also have advantages of long working life and being mercury-free.
  • the main activity relating to road lighting equipment will be to replace the conventional street lamps with the LED street lamps in the future.
  • the brightness of an LED device can be further controlled by using a digital control circuit.
  • a digital control circuit can improve the efficiency of the electrical energy, and the LED device can be adjusted to emit extra bright light when needed, for example at times of rain or fog.
  • the small size and flat package of the LED device allows the LED to be applied to a wider variety of lighting apparatuses compared to the conventional lamps.
  • the colored lights of different-colored LED devices are easily recognized, and hence, are suitable for use with traffic-control lights.
  • a familiar street lamp comprises a lighting source and a protective shield. Such a simple combination cannot have any additional functions, and the purpose of the street lamp is simple. Furthermore, the current LED street lamp still follows the design of the conventional street lamp, and does not sufficiently develop the advantages of the LED devices. Therefore, the current LED street lamp cannot have more additional functions to promote its purposes and results.
  • the present invention provides a street lamp comprising a lamp body and a first LED module.
  • the lamp body has a lighting source for road illumination.
  • the first LED module is disposed on the lamp body and acts as an indicator for drivers to be given an early notice of an upcoming traffic light.
  • the present invention provides a street lamp comprising a lamp body and at least one first LED module.
  • the first LED module is disposed on the lamp body and is directed toward oncoming traffic.
  • the present invention provides an LED street lamp with an indication synchronized with a nearby traffic light.
  • the street lamp comprises a lamp body and a plurality of first LED modules.
  • the lamp body has a lighting source for road illumination.
  • the plurality of first LED modules corresponds to the traffic light and is disposed on the lamp body.
  • the plurality of first LED modules is directed toward oncoming traffic.
  • the lighting source for road illumination is a second LED module.
  • the second LED module comprises a plurality of white LEDs or a plurality of LEDs with complementary colors to generate white light.
  • FIG. 1 illustrates a schematic diagram of an LED street lamp 100 in accordance with an embodiment of the present invention.
  • the street lamp 100 of the present invention comprises a lamp body 102 which includes at least one auxiliary light source 104.
  • the auxiliary light sources 104 are disposed on a side surface of the lamp body 102 for showing the indication of the traffic light.
  • a plurality of auxiliary light sources 104 corresponding to the traffic light 106 is disposed on a side surface of the lamp body 102.
  • the plurality of auxiliary light sources 104 is directed toward oncoming traffic so that drivers or passerby can observe the indication of the upcoming traffic light.
  • the auxiliary light sources 104 can emit red light, yellow light and green light, so as to indicate the signal of an upcoming traffic light 106.
  • the lamp body 102 can be placed where the traffic light 106 is shielded from view, e.g. near a curve in the road or a hill. Therefore, drivers or passerby can be alerted to the indication of the traffic light 106 before coming into view of the traffic light, and can therefore prepare for the according driving action. Accordingly, sudden reaction to an unexpected signal is avoided, and the driving safety is improved.
  • Using the techniques of the present invention can improve the functions and results of the street lamp 100, and can reduce the need for additional traffic lights.
  • the auxiliary light sources 104 can act not only as indicators synchronized with traffic lights 106, but also as a display for the traffic control center to show the information of traffic accidents, road construction, and weather. Furthermore, the auxiliary light sources 104 with colorful light can be used as decorative light for celebrating festivals or holiday activities.
  • FIG. 2 illustrates a schematic diagram of a lamp body 102 of an LED street lamp in accordance with an embodiment of the present invention.
  • the lamp body 102 comprises a second LED module 208 for road illumination.
  • a heat dissipation partition 206 and a heat dissipation module 204 are disposed on the surface in back of the lighting surface.
  • the heat dissipation module 204 comprises a plurality of heat dissipation fins. Through the heat dissipation module 204, the heat generated from the second LED module 208 which emits light is transferred to the surrounding air.
  • An external cover 202 contains the auxiliary light sources 104, the heat dissipation module 204, the heat dissipation partition 206, and a second LED module 208.
  • the external cover 202 comprises a lighting window 210 and a heat dissipation opening 212.
  • the light emitted from the second LED module 208 passes through the lighting window 210 and illuminates the road surface.
  • the heat dissipation opening 212 allows the heat dissipation module 204 to conduct the heat to the exterior of the lamp body 102.
  • the lighting window 210 of the external cover 202 can be shielded by a housing 218.
  • the housing 218 can be a lens so that the light will be convergent rather than divergent.
  • the second LED module 208 comprises a plurality of white LEDs or a plurality of LEDs with complementary colors to generate white light.
  • Each of the auxiliary light sources 104 comprises a first LED module 214 serving as a light source.
  • FIGs. 3 and 4 illustrate a schematic diagram of a first LED module in accordance with an embodiment of the present invention.
  • the auxiliary light sources 104 act as the application of the traffic light, but the applications of the present invention are not limited by these embodiments.
  • the auxiliary light sources 104 comprise a first LED module 214 serving as a light source.
  • the first LED module 214 can be a red LED module 214a, a yellow LED module 214b and a green LED module 214c.
