Abstract
The utility model relates to a white light power LED intelligent street lamp, particularly for the illumination of primary and secondary main urban roads. The utility model belongs to the technical field of a municipal street lamp. In the utility model, an LED is installed on an aluminum strip. The aluminum strip is installed on a heat-dissipating aluminum plate. The heat-dissipating aluminum plate is installed inside the light fixture casing and divides the light fixture casing into a light fixture optical cavity and a light fixture electrical cavity. A heat dissipater is installed on top of the heat-dissipating aluminum plate. A heat-dissipating fan is installed on one side of the heat dissipater. A micro-thermal relay is installed at the center of the heat-dissipating aluminum plate. A controller is installed at the wire inlet of the light fixture casing. The utility model has a simple, compact and reasonable structure, a long service life which is more than five times that of a high-voltage sodium lamp. The LED is a resistive load and will not pollute the electric network, reactive power is not lost, therefore the power is consumed less (energy saving). The white light power LED is an environment-friendly light source, with no harm to human body and environment, with good color rendering of white light and good for the security of a passer-by and traveling vehicles.
Description
Technical field
The utility model relates to the power led intelligent street lamp of a kind of white light, specifically is used for the illumination of urban road main and secondary road, belongs to the municipal road lamp technical field.
Background technology
Before the utility model is made, in prior art, be used for the municipal road lamp that urban road main and secondary road street lamp throws light on and normally form between 8 meters～15 meters by ballast, high-pressure mercury lamp, lamp casing and lamp stand etc.Adopt 220V voltage to enter ballast, ballast connects high-pressure mercury lamp by lead, and high-pressure mercury lamp is packed in the lamp casing, and is contained on the lamp stand.The street lamp of this kind structure easily produces pollution to electrical network, and energy loss is big, and service life is short; The high-pressure mercury lamp color is yellow, and colour rendering is poor, and pernicious gas such as mercurous, therefore, environment is easily produced pollution, is harmful to the healthy of people.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned weak point, can produce the required mean flow rate of road lighting (or average illumination) and the uniformity thereby provide a kind of, guarantees the pedestrains safety of driving a vehicle; The heat that sends in the time of can be with the power led work of white light dissipates, and keeps normal operating temperature, guarantees the power led intelligent street lamp of white light in service life.
Main solution of the present utility model is achieved in that
The utility model mainly adopts light emitting diode 10 to be contained on the light emitting diode aluminum strip 9, light emitting diode aluminum strip 9 is contained on the heat-dissipating aluminium plate 8, between heat-dissipating aluminium plate 8 and light emitting diode aluminum strip 9, scribble heat-conducting silicone grease, heat-dissipating aluminium plate 8 is contained in the lamp casing 4, lamp casing 4 is divided into light fixture optics cavity 3 and the electric chamber 5 of light fixture, radiator 6 is housed above heat-dissipating aluminium plate 8, radiator fan 1 is contained in radiator 6 one sides, miniature electrothermal relay 7 is contained in heat-dissipating aluminium plate 8 centers, and controller 2 is contained in lamp casing 4 incoming lines.
Compared with the prior art the utility model has the following advantages:
The utility model is simple, compact and reasonable for structure; Long service life is more than five times of high-pressure mercury lamp; Light emitting diode is a resistive load, can not produce pollution to electrical network; Owing to be resistive load, there is not the loss of reactive power, so power consumption little (energy-conservation); White light is power led to be green light source, to human body and environmentally friendly, is white light, and colour rendering is good, helps pedestrian's traffic safety.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model control principle block diagram.
The specific embodiment
Embodiment during following the utility model is incited somebody to action in conjunction with the accompanying drawings is further described:
The utility model mainly is made up of radiator fan 1, intelligent controller 2, light fixture optics cavity 3, lamp casing 4, the electric chamber 5 of light fixture, high-efficiency radiator 6, miniature electrothermal relay 7, heat-dissipating aluminium plate 8, light emitting diode aluminum strip 9, light emitting diode 10 etc.Adopt light emitting diode 10 to be contained on the light emitting diode aluminum strip 9,10 connection in series-parallel are arranged in diode group (uniform) according to the power requirement light emitting diode.Light emitting diode aluminum strip 9 is contained on the heat-dissipating aluminium plate 8, between heat-dissipating aluminium plate 8 and light emitting diode aluminum strip 9, scribble heat-conducting silicone grease, heat-dissipating aluminium plate 8 is contained in the lamp casing 4, lamp casing 4 is divided into light fixture optics cavity 3 and the electric chamber 5 of light fixture, radiator 6 is housed above heat-dissipating aluminium plate 8, between heat-dissipating aluminium plate 8 and radiator 6, also evenly coats heat-conducting silicone grease.Radiator fan 1 is contained in radiator 6 one sides, and miniature electrothermal relay 7 is contained in heat-dissipating aluminium plate 8 centers, and the operating temperature of electrothermal relay is an extremely temperature of the power led maximum of white light.Controller 2 is contained in lamp casing 4 incoming lines, and lamp casing 4 is contained on the lamp stand.
Shown in the utility model control principle block diagram: adopt the 220V alternating current behind DC power supply circuit, to be divided into two-way, one the tunnel enters power led group of required operating voltage of white light, so delivers to power led group of white light (constant current value equals the power led operating current of white light) again through constant-current circuit.Another road enters control circuit, and on the one hand the output valve of constant-current circuit is progressively to rise to rated value by 0 during the control energising, and control energising back 5 hours (can adjust) plays constant-current circuit and falls stream power supply (economize on electricity) until outage on the other hand.
Operation principle of the present utility model:
The power led function of white light is generation the road lighting required mean flow rate (or average illumination) and the uniformity, guarantees the pedestrains safety of driving a vehicle.The function of cooling system be the heat that sends during with the power led work of white light dissipate, keep normal work extremely temperature, guarantee its service life.The function of intelligent controller is driving power required when converting the 220V alternating current to white light power led operate as normal and constant current, has soft start (electric current progressively increases to rated value during energising) and half-power power supply in a late into the night intelligent functions such as (economize on electricitys) simultaneously.The function of light fixture is rainproof, dustproof and anti-electromagnetic interference etc.
