The technical scheme that the utility model provides is: integrated high-power LED road lamp cap, comprise the constant-current source circuit plate, light source bracket, lamp stand junction and the light source module that is installed on the light source bracket, light source module comprises light source heat radiation device and the led light source and the light lens that are installed on this light source heat radiation device, each led light source is lined up array by the LED bulb of several 1～5W and is formed, described constant-current source circuit plate can be given each light source module constant current power supply respectively, and be installed in hermetically in the cavity of making by the material of perfect heat-dissipating, an end of light source bracket is connected with described cavity.
Described each led light source power is 20～50 watts, and 2 above light source modules are installed on each radiator.
Described cavity is the die casting aluminium cavity, and described radiator is the high-power radiator of die casting aluminium.
Further, described integrated high-power LED road lamp cap also comprises the decoration empennage, and this is decorated empennage and is connected with the other end of light source bracket.
If led light source self lighting angle is suitable, can select the transparent plastic plano lens because plano lens thickness is even everywhere, just as plate glass, can not produce any influence to the led light source lighting angle.Light lens only plays the effect of sealing protection cover like this.
If need the rectangular light illumination, can select rectangular light transparent plastic lens, led light source can form the rectangular light field of illumination on the ground through the rectangular light lens.
Light lens in the utility model is made by transparent plastic, has double action, is lens, also is protective cover simultaneously.Have the function of lens on the one hand, the lighting angle that can change led light source as required makes it to meet the requirements; Also light source is played a part printing opacity and seal protection on the other hand as the transparent shield of light source.
Light source heat radiation device in the utility model provides extraordinary radiating condition to led light source on the one hand, also uses as lamp housing on the other hand.
Of the present utility model have a following advantage:
(1) led light source in the utility model is lined up array by the LED bulb of a plurality of 1～5W and is formed,, its power is 20～50 watts, and a led light source and a light lens can be installed on each light source heat radiation device, this has just constituted a light source module.Two such light source modules can be installed on each light source bracket.One to three such lamp bracket can be installed on each lamp holder.The light source heat radiation device is the high-power radiator of aluminium die casting, and each radiator can carry the heat dissipation capacity of the above led light source of 50W, good heat dissipation effect.
(2) integrated design of light lens and lampshade: light lens is made by transparent plastic, has double action, is lens, also is protective cover simultaneously.Have the function of lens on the one hand, the lighting angle that can change led light source as required makes it to meet the requirements; Also light source is played a part printing opacity and seal protection on the other hand as the transparent shield of light source.
(3) integrated design of light source heat radiation device and lamp housing: radiator provides extraordinary radiating condition to led light source on the one hand, also uses as lamp housing on the other hand.
(4) modularized design: the utility model is made up of light source module, light source aluminum frame, die casting aluminium cavity and decorative plastic empennage, on each light source aluminum frame two light source modules can be installed; Can need increase the quantity of light source bracket and light source module according to light source power.Each light source module can be installed 20～50 watts of led light sources, and each light source bracket can be installed 2 light source modules can reach 100 watts of led light sources altogether, and three light source brackets can be installed 6 light source modules and can reach 300 watts of led light sources altogether.The light source general power can be adjusted between 20～300 watts as required.
(5) appearance and modeling is attractive in appearance: airflow design, and elegant in appearance.
(6) luminous efficiency height, obvious energy conservation.Led light source efficient can reach 100 lumens/watt, and constant-current source circuit efficient can reach 95% during direct current supply, and constant-current source circuit efficient can reach 90% during Alternating Current Power Supply.With 200 watts of input electric power led light sources is example, 200 watts * 95% * 100 lumens/watt=19000 lumens.Because the LED lighting source does not need reflection shield to shine white light 100% on the ground, utilization rate is very high.
Corresponding, general street lighting uses high-pressure mercury lamp.Its light efficiency also is 100 lumens/watt, but because the existence of ballast, the efficient of its power supply circuits has only about 70%, considers that again its lighting angle is a sphere, is to add reflection shield its efficiency of light energy utilization also lower (calculating according to 70%); All take into account for two, shine ground luminous energy and be: 200 watts * 70% * 70% * 100 lumens/watt=9800 lumens, have only 51% of led light source, promptly about half.200 watts led light source can be equivalent to 400 watts high-pressure mercury lamp.
(7) supply voltage is optional: direct current+12V, and+24V ,+48V, civil power AC220V all can.
