Abstract

LED (light emitting diode) road lamp, by LED lamp pearl, grading lens external member, cable connector, drive power supply, the power mounting panel, the housing main body, the strengthening rib, the arm mounting bracket, the backplate, the protecgulum is constituteed with the back lid, the strengthening rib is fixed on the housing main body, the design of housing main body type of being arc, the left and right sides and the bottom side of housing main body set up air current heat dissipation channel, the LED lamp is fixed on the housing main body by the pearl, join in marriage assembly optical lens external member on the LED lamp pearl, realize automatic pretension with drive power supply and power mounting panel combination back through the edge of power mounting panel and the T type spout on the strengthening rib, then in pushing the T type spout to the strengthening rib on with the arm mounting bracket again behind cable connector and the LED lamp connection, both ends around the housing main body are fixed with the back lid to the protecgulum. The utility model discloses realizing lamps and lanterns convection current, conduction and thermal -radiating optimization, having reduced the wasting of resources of heat sink material, drive power supply installs and use spout pretension structure simultaneously, when the worker had not only been practiced thrift to plug -type installation but also solved the phenomenon that on -the -spot change power took time to take a lot of work.

Description

LED street lamp

Technical field

This utility model relates to field of illumination lamp technology, is specifically related to a kind of LED street lamp.

Background technology

Current LED lamp is widely used to all trades and professions, and especially roadway illumination occupies the very big market share.It is known that the heat radiation of LED lamp is always up a rigid index of light fixture, except die casting aluminium heat radiation is extruded aluminium heat radiation, or both combinations, but the light fixture on market has been generally solution heat dissipation problem attends to one thing and lose sight of another, the waste of light fixture heat sink material is too many, do not reach the radiating requirements of light fixture itself, the intensity of What is more even light fixture itself is all without making reasonable guarantee, both made that light fixture is functional be can not be guaranteed, it is substantially reduced in safety again, more without the aesthetic property of hand lamp tool.

Utility model content

This utility model provides a kind of LED street lamp, and the heat sink material existed to solve prior art uses the problem too much causing that cost increases and heat dispersion is bad.

This utility model solves its technical problem and be the technical scheme is that

A kind of LED street lamp, by LED lamp bead, light-distribution lens external member, cable connector, drive power supply, power supply installing plate, housing main body, reinforcement, arm installing rack, backboard, protecgulum and bonnet composition, reinforcement is fixed on housing main body, housing main body is class cambered design, the left and right sides of housing main body and bottom side arrange airflow radiating passage, LED lamp bead is fixed on housing main body, equipped light-distribution lens external member in LED lamp bead, automatic pretension is realized by the edge of power supply installing plate with the T-shaped chute on reinforcement after driving power supply and the combination of power supply installing plate, then pass through and again arm installing rack is pushed in the T-shaped chute on reinforcement after cable connector is connected with LED lamp bead, protecgulum and bonnet are fixed on the rear and front end of housing main body.

While class arc heat-dissipating casing of the present utility model forms thermal conduction path, the rising that bottom lamp outer casing, airflow radiating passage with top is thermal current provides passage, class arc shell side and bottom surface bossing are automatically intercepted and captured air and are formed forced ventilation, and use novel high polymer heat loss through radiation sprayed on material to achieve light fixture convection current on this basis, conduction, thermal-radiating comprehensive optimization, reduce further the wasting of resources of heat sink material, arm installing rack interts with the grooved of reinforcement and coordinates the load-carrying members optimizing light fixture, before avoiding, all load-bearing of LED lamp all concentrate on the phenomenon of light fixture afterbody, and thereby design achieves light fixture monoblock type load-bearing and combines with heat radiation；Not only installing and using chute pre-pressing structure for what drive power supply, simple plug-type installation has been saved manufacturing man-hours but also has been solved and on-the-spot changed the time-consuming phenomenon taken a lot of work of power supply, has that heat radiation is good, elegant in appearance and the advantage of low cost of manufacture.

1 protecgulum, 2 housing main bodies, 3 bonnets, 4 light-distribution lens external members, 5LED lamp bead, 6 cable connectors, 7 backboards, 8 power supply installing plates, 9 driving power supply, 10 reinforcements, 11 arm installing racks, 12 airflow radiating passages, 13T type chutes in figure.

Detailed description of the invention

Such as Fig. 1, Fig. 2, shown in Fig. 3 and Fig. 4, a kind of LED street lamp, by LED lamp bead 5, light-distribution lens external member 4, cable connector 6, drive power supply 9, power supply installing plate 8, housing main body 2, reinforcement 10, arm installing rack 11, backboard 7, protecgulum 1 and bonnet 3 form, reinforcement 10 is fixed on housing main body 2, housing main body 2 is in class cambered design, the left and right sides of housing main body 2 and bottom side arrange airflow radiating passage 12, LED lamp bead 5 is fixed on housing main body 2, LED lamp bead 5 is equipped with light-distribution lens external member 4, automatic pretension is realized by the edge of power supply installing plate 8 with the T-shaped chute 13 on reinforcement 10 after combining by driving power supply 9 and power supply installing plate 8, then pass through and again arm installing rack 11 is pushed in the T-shaped chute 13 on reinforcement 10 after cable connector 6 is connected with LED lamp bead 5, protecgulum 1 and bonnet 3 are fixed on the rear and front end of housing main body 2.

While class arc heat-dissipating casing of the present utility model forms thermal conduction path, the rising that bottom lamp outer casing, airflow radiating passage with top is thermal current provides passage, class arc shell side and bottom surface bossing are automatically intercepted and captured air and are formed forced ventilation, and use novel high polymer heat loss through radiation sprayed on material to achieve light fixture convection current, conduction, thermal-radiating comprehensive optimization on this basis, reduce further the wasting of resources of heat sink material；Arm installing rack interts with the grooved of reinforcement and coordinates the load-carrying members optimizing light fixture, it is to avoid before all load-bearing of LED lamp all concentrate on the phenomenon of light fixture afterbody, and thereby design achieves light fixture monoblock type load-bearing and combines with heat radiation；Not only installing and using chute pre-pressing structure for what drive power supply, simple plug-type installation has been saved manufacturing man-hours but also has been solved and on-the-spot changed the time-consuming phenomenon taken a lot of work of power supply, has that heat radiation is good, elegant in appearance and the advantage of low cost of manufacture.
