A kind of High-Pole Lamp
Technical field
The present invention relates to the high bar LED light fixture of a kind of high brightness, big regional illumination, relate in particular to a kind of High-Pole Lamp tool that harbour, harbour, construction site etc. need high brightness, big area illumination occasion that is applied to.
Background technology
At the harbour, occasions such as harbour, stadiums, airport, goods yard, construction site, need to use light fixture with strong illumination ability.Present High-Pole Lamp refers generally to the novel lighting apparatus that steel column type lamp stand and high-power assembling lamp are configured to more than 15 meters.It is electric by lamp holder, inner light fixture, the body of rod and foundation are formed.Inner light fixture is many to be made up of floodlight and Projecting Lamp, and it is the above high-pressure mercury lamp of 400W that light source mostly adopts power, and the illumination radius reaches 60 meters.But the problem of this kind lighting maximum is that energy consumption is big.
Development along with the semiconductor lighting technology, led light source is generally used above-mentioned occasion, for guaranteeing illumination requirement, needing to adopt some led light sources to form an area source throws light on, defective is obviously: the one, and the volume of lighting is big, installation difficulty is big, especially has many safety issues in the high-altitude; The 2nd, the luminous intensity distribution difficulty is big, and its effective lighting radius is difficult to guarantee.At present LED integrated optical source is widely used, but the obstacle of using this new product maximum is to use in the process not heat sink scheme efficiently.
The applicant has proposed the patent application that a name is called " a kind of High-Pole Lamp lamp holder " in 2010.1. to State Intellectual Property Office, and authorizes in the 2010.10.6 bulletin.It provides a kind of lamp body is oblate cylindricality, have a plurality of lamp holders, and the field of illumination is roughly circular High-Pole Lamp.But some operation occasion needs the length of field of illumination bigger, and width requirement is little, such as harbour, harbour.
Summary of the invention
The present invention is directed to above problem, provide a kind of illumination projected area to be roughly ellipse, and the High-Pole Lamp of good heat dissipation effect.
Technical scheme of the present invention is: comprise led light source and driving power, also comprise being blocked by section bar and make and have lamp body, the lamp holder of heat radiation wing and be arranged on reflection shield in the lamp holder; Both sides are to have the cydariform that protrudes camber line on the described lamp body cross section, are provided with the trapezoidal groove that is used to connect described lamp holder in the lamp body in cydariform cross section, and described heat radiation wing is located at the both sides and the top of described lamp body; The top of described lamp holder contacts the end face of described trapezoidal groove.
Described lamp holder is provided with two at least.
Also comprise the radiator by the wife, the cross section of described wife's radiator is umbrella shape, and the bottom has a plurality of heat radiation wings, and the top has and is used for fixing the plane that connects described trapezoidal groove end face.
The end of described wife's radiator is curved, and is suitable with the arc of described lamp holder side, and keeps in touch.
The axial section shape of described lamp holder is and adaptive trapezoidal of described trapezoidal groove; The both sides of described trapezoidal groove lower edge have inside flange respectively, are used for the lower edge of the described lamp holder of support.
The overall profile of High-Pole Lamp lamp body of the present invention is cuboid, and lamp holder is set up in parallel, the regional ovalize that makes illumination like this, the occasion in the big area illumination of needs zones such as suitable harbour, railway goods yard.For improving sink effect, three of lamp body all are provided with the heat radiation wing, and the end face of lamp holder contacts with the end face of lamp body inner groovy, form " thermo-contact " effect; And between lamp holder and lamp holder, the outside of outermost lamp holder is provided with wife's radiator respectively, strengthens the heat radiation between the lamp holder.Because High-Pole Lamp is suspended on the higher position for a long time, bear and expose to wind and rain, be to increase connection reliability, can also with lamp holder by pull groove (being the flange of groove both sides) " chimeric " in lamp body, add securing member again, guaranteed the reliability and the steadiness of connection.

The specific embodiment
The present invention comprises led light source 3 and driving power 5 shown in Fig. 1-4, also comprise being blocked by section bar making and having lamp body 1, the lamp holder 10 of heat radiation wing and be arranged on reflection shield 2 in the lamp holder; In some heat radiation wings at lamp body 1 top, be provided with link slot 7, be used to be provided with connecting bolt 6, and then can driving power 5 be connected the top of lamp body 1 by the fixing card 4 of driving power.
Both sides are to have the cydariform that protrudes camber line on described lamp body 1 cross section, are provided with the trapezoidal groove 9 that is used to connect described lamp holder 10 in the lamp body 1 in cydariform cross section, and described heat radiation wing is located at the both sides and the top of described lamp body 1; The end face of the described trapezoidal groove 9 of (lamp holder) top 11 contacts of described lamp holder 10.
Described lamp holder 10 is provided with two at least.
Comprise that also by wife's radiator 8, the cross section of described wife's radiator 8 is umbrella shape, the bottom has a plurality of short and small heat radiation wings, and the top has and is used for fixing the plane that connects described trapezoidal groove 9 end faces.
(wife's radiator) end 12 of described wife's radiator 8 is curved, and is suitable with the arc of the side on described lamp holder 1 top 11, and keeps in touch.To increase thermal conduction effect.
Another embodiment of the present invention is shown in Fig. 3,4, and the axial section shape of described lamp holder 10 is and adaptive trapezoidal of described trapezoidal groove 9; The both sides of described trapezoidal groove 9 lower edges have inside flange respectively, are used for the lower edge of the described lamp holder 10 of support.Like this, lamp holder 10 can be connected the middle trapezoidal groove 9 of lamp body 1 very reliably, even if the hidden danger that does not also drop occurs shaking, rocking.Trapezoidal groove 9 is a groove in addition, and lamp holder 10 can be injected in the groove by any end at two ends, and the structure of groove also helps to ventilate, heat radiation.
