Abstract
Disclosed is an LED street lamp fitting, comprising an electric source cavity and a light source cavity which are separate. An LED light source is installed in the light source cavity; an electric source control circuit is installed in the electric source cavity; a lamp post mounting tube is arranged above the lamp fitting; and cooling fins are arranged at two sides of the lamp post mounting tube. The lamp fitting is divided into two separate rooms, and the heat sources are separated and do not interfere each other, so the heat dissipation performance is remarkably improved, and the work stability of the lamp fitting is obviously improved. Meanwhile, since the lamp post mounting tube is arranged at the outside, the street lamp is more convenient to install.
Description
Technical field
The utility model relates to a kind of LED street lamp, particularly a kind of high-power LED street lamp fixture.
Background technology
Because semiconductor lighting has efficiently, energy-saving and environmental protection, long service life, response speed soon, remarkable advantages such as vibration resistance, easy care, be acknowledged as the novel solid-state cold light source that most possibly enters the general illumination field in the world.Substitute electron tube as transistor, it also is trend of the times that semiconductor lamp replaces traditional incandescent lamp and fluorescent lamp.
The LED street lamp not only has the characteristics that colourity is good, non-maintaining, the life-span is long, the more important thing is more energy-conservation than conventional road lamp.But existing LED street lamp mainly adopts low-power LED (less than 0.5 watt) to make light source, because the luminous flux of low-power LED is little, each street lamp needs hundreds of LED, has limited the total light flux of LED street lamp, can't satisfy the needs in different markets.
Using great power LED is a kind of desirable selection as the illuminating device of street lamp.But, for LED, merely increasing input power, the brightness meeting is risen pro rata.Because the efficient of LED is far from reaching 100%, can produce heat in the course of the work, power and chip area increase, and heat flow density is with regard to corresponding increasing.Because during large-power light-emitting diodes work, heat concentrates in the small-sized chip, makes that the temperature of chip internal is more and more higher.Chip temperature raises, and can cause that non-uniform Distribution, chip light emitting efficient and the fluorescent material of thermal stress swashs problems such as penetrating decrease in efficiency, and when temperature surpassed certain value, the crash rate of device is index law to be increased.Statistics shows, 2 ℃ of the every risings of component temperature, reliability decrease 10%.When a plurality of LED dense arrangement, when forming white lumination system, the dissipation problem of heat is even more serious.
Secondly, general LED street lamp is the inside that power control circuit is installed in radiator at present, the heat accumulation that heat that light source works is sent and power control circuit work are sent is in the environment of a high temperature power control circuit in the heat radiation body cavity for a long time.Since the temperature characterisitic of power control circuit and antijamming capability a little less than, source element has directly been caused very big influence, externally during 40 ℃ of environment temperatures, heat radiation body cavity internal temperature can reach 80 ℃, significantly reduced (though be-40～105 ℃ in the life-span of power control circuit as the nominal temperature of electric capacity, but actual working environment is in case above 80 ℃, and capacitance will reduce half, electric capacity that some are second-rate even meeting explosion.Simultaneously under such environment temperature, it is extremely unstable that resistance, transistorized performance also become, and makes the street lamp can not steady operation).Therefore, power control circuit is installed in the endoceliac way of heat radiation, makes be subject to the power control circuit part service life of entire product, and can't bring into play the LED feature of long life to greatest extent.
Summary of the invention
The purpose of this utility model provides a kind of new LED road lamp, more effectively to improve the radiating effect of LED street lamp, makes the easier for installation of street lamp simultaneously.
LED road lamp of the present utility model comprises:
A light source cavity that is positioned at the light fixture rear end is made of jointly keel piece, dividing plate and rear end cap, and portion is installed with at least one led light source within it, and the surface of light source cavity is sealed by cloche;
A power supply cavity that is positioned at the light fixture front end, constitute jointly by upper end cover, dividing plate with dividing plate all-in-one-piece lower cover, and separate by dividing plate with the light source cavity, its internal fixation is equipped with power control circuit, upper end cover is movably connected on the lower cover, can open;
A lamp stand mounting pipe that is positioned at light source cavity top becomes one with keel piece, is used for light fixture is fixed on lamp stand;
And
Two groups of heat-dissipating fins are movably connected on the keel piece, and lay respectively at the both sides of light source cavity top lamp stand mounting pipe.
Wherein, described lamp stand mounting pipe is communicated with the power supply cavity, is provided with wire through-hole simultaneously on the dividing plate between power supply cavity and the light source cavity, power line is introduced in the power supply cavity from lamp stand, after connecting power control circuit, by passing in the wire through-hole on the dividing plate, be connected again with led light source.
The utility model also directly is connected led light source on the inner surface of heat-dissipating fin.
The utility model has been broken through the traditional design of road lamp, light fixture is divided into independently space of two of light source cavity and power supply cavitys, thermal source is separated, do not disturb mutually, make the heat effects that power control circuit is not sent by the led light source in the light source cavity, the power supply cavity is communicated with the lamp stand pipeline simultaneously, can use the lamp stand pipeline and carry out circulation of air, help the power control circuit heat extraction, increased the reliability of power control circuit work.
Light fixture radiator portion of the present utility model is made up of two groups of heat-dissipating fins and lamp stand mounting pipe, heat-dissipating fin and lamp stand mounting pipe adopt the high heat conduction aluminium of high density to draw and form, heat-dissipating fin adopts the design of ladder arc wind-guiding, make the easy convection current of heat of heat-dissipating fin, improved the heat dispersion of light source cavity.
LED road lamp of the present utility model is external with the lamp stand mounting pipe, and easy-to-connect is installed, and only needs lamp stand is inserted in the mounting pipe, tightens hold-down screw, and the upper end cover of opening power cavity is connected power line on the power control circuit, and the upper end cover that closes again gets final product.
The utility model directly is connected led light source on the inner surface of heat-dissipating fin, and the matrix end face of the heat sink and heat-dissipating fin at the led light source back side is directly contacted, and has reduced the heat radiation link, has improved the capacity of heat transmission of heat-dissipating fin.
LED road lamp of the present utility model is owing to adopted said structure, and heat dispersion obviously improves, and job stability obviously improves, thereby has guaranteed that the LED street lamp works for a long time reliably.
