Abstract
The invention discloses a street lamp which takes a light emitting diode (LED) as a light source. The street lamp comprises a radiating lamp body, a power source cover board, a plurality of 1-3W (Watt) LED lamp beads which are provided with rectangular light distribution lenses, and a constant current power supply. The street lamp has the structure that the light source is located at the front side of the radiating lamp body; the constant current power supply is located at the backside of the radiating lamp body; a light source cavity is a flat-bottomed groove formed in the front side of the radiating lamp body which is made of extruded aluminum or copper material, and is covered by a plastic cover board which is integrally formed with the light source cavity and is provided with a glass window; a power supply cavity is a flat-bottomed groove formed at the middle part on the backside of the radiating lamp body which is made of extruded aluminum or copper material, and is covered by a plastic cover board which is integrally formed with the power supply cavity; and black screen printing is conducted on the outer edges of the corresponding rectangular glass windows above all the LED lamp beads.
Description
Technical field
The present invention relates to a kind of structure of light emitting diode road lamp.
Background technology
Lifting along with the LED source light efficiency, light emitting diode causes the interest that industry is very large in the application of lighting field. utilize light emitting diode as light source, light efficiency and light source life can be significantly improved .. for the application of light emitting diode on street lamp, present most street lamp adopts the light emitting diode of 1W or the above encapsulation of 1W to make up to reach the effect of road lighting as base unit. general, light emitting diode road lamp can be directly with single 1 watt to 3 watts light emitting diode combined body of rectangle luminous intensity distribution as light source.With traditional high-pressure mercury lamp, Metal halogen lamp is compared has high light efficiency to light emitting diode as a kind of solid-state illumination light source, long-life, the easily characteristics of luminous intensity distribution.Case of the present invention has proposed class employing and has carried 1-3 watt of light emitting diode of rectangle luminous intensity distribution as the lamp post structure of light source, it comprises heat radiation body, light emitting diode module and driving power. light-source chamber and two cavitys of power source cavity of half opening are arranged in the heat radiation body. its structure is, light-source chamber is positioned at the front of heat radiation body, and power source cavity is positioned at the back side of heat radiation body. and the installed part structure links to each other by screw with the end of heat radiation body.Heat radiation body is the aluminum extruded lamp body of similar rectangle.Light-source chamber is one flat bottomed recess on the front of heat radiation body of aluminum extruded material, and the above uses plastic cover plate with glass window by the edge of screwed lock in light-source chamber.Power source cavity is supermedial one flat bottomed recess in the back side of the heat radiation body of aluminum extruded material, the above covers with a plastic cover plate. and the bottom of driving power and power source cavity is close to dissipation of heat is gone out. for the consideration of water proof and dust proof, LED light source module base outer rim in plastic cover plate and light-source chamber has silicone gasket. and on an aluminium base, the peripheral edge portion of corresponding rectangle glass window has the black serigraphy to process directly over every lamp pearl by surface mount for packaged 1-3 watt of single LED lamp bead.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of succinct, novel light-emitting diode street lamp structure.
The technical solution adopted in the present invention is:
1. a class adopts light emitting diode as the street lamp of light source, and it comprises heat radiation body, optical source cover board, power supply cover plate, light emitting diode module and constant-current supply. and its structure is, light source is positioned at the front of heat radiation body, and power source cavity is positioned at the back side of heat radiation body.
2. heat radiation body as claimed in claim 1 is characterized in that, heat radiation body is that similar rectangle aluminium or copper are extruded lamp body.
3. light-source chamber as claimed in claim 1 is characterized in that, light-source chamber is one flat bottomed recess on the front of aluminium or the copper heat radiation body of extruding material, and the above covers with integrally formed plastic cover plate.
4. power source cavity as claimed in claim 1 is characterized in that, power source cavity is supermedial one flat bottomed recess in the back side of aluminium or the copper heat radiation body of extruding material, and the above covers with a plastic cover plate.
5. light emitting diode module as claimed in claim 1 is characterized in that, packaged 1-3 watt of LED lamp bead with the rectangle light-distribution lens by surface mount on an aluminium base.
6. plastic cover plate as claimed in claim 3 is characterized in that, the plastic cover plate zone line has glass window, and glass has the rectangular window that is centered on by black ink over against the position of LED lamp bead.
After adopting technique scheme, the present invention is dispelled the heat to LED source and power supply by adopting same aluminium or copper to extrude heat radiation body, the reliability problem of effectively having avoided power supply to cause because of the deficiency of dispelling the heat.In addition, power supply and light source share the material that a heat radiation body can significantly be saved heat radiation body, have supported energy-saving and emission-reduction at raw material.
Another innovation of case of the present invention is a specially treated on the glass window of light-source chamber, has done the black serigraphy on the glass window, has just stayed the transparent window of rectangle directly over every light emitting diode.Although process like this and can lose some light, can significantly improve dazzle and the yellow dizzy problem of light emitting diode road lamp, can obtain the desirable rectangle luminous intensity distribution that is applicable to road lighting simultaneously.
The specific embodiment:
Below in conjunction with accompanying drawing the present invention is made and to further specify
Embodiment 1, shown in figure (1), the positive back side has the aluminium matter of radiating fin or front and the back side of copper heat radiation body 1 all to have a cavity, a plural number LED lamp bead 2 with the rectangle light-distribution lens is fixed on the aluminium base 3 by surface mount process, and aluminium base 3 is fixed on the front of heat radiation body 1 by screw. toply fix again an integrated plastic cover plate 5 with cloche; Constant-current supply 4 is fixed on the back side of heat radiation body 1, is covered with equally integrated plastic cover plate 6; Shown in figure (2), the peripheral edge portion of corresponding rectangle glass window 30 has black screen printed pattern 40 to process directly over every LED lamp bead, and the length of the rectangle of rectangle glass window 30 is similar to the length-width-ratio of the rectangle light distribution patterns of LED lamp bead to wide ratio.
