Abstract

The invention discloses a transverse fin radiating type strip high-power LED street lamp, which comprises an integrated lamp holder, an end tail closing plate, an LED chip module and a light transmitting plate. The integrated lamp holder consists of a lamp holder plate block, a butt plate, a mounting sleeve, radiating fins and a ridge and is made of an aluminum material by primary die casting. The invention is mainly characterized in that: 1, the radiating fins are transversely designed, namely that the plane of the radiating fins is vertical to the longitudinal direction of the lamp holder plate block, and the radiating fins are longitudinally and uniformly arranged on the back of the lamp holder plate block; and 2, the length-width ratio of the effective surface of the lamp is more than 2:1. Due to the strip tile-shaped scroll lamp holder and the transverse radiating fins of the lamp, the radiating fins and the lamp have better permeability in the air, and the overall radiating effect of the lamp is improved to a large degree, therefore the convergence phenomenon of the heat energy produced by the LED chip is avoided, thereby being favorable for further improving the light efficiency of the LED and prolonging the service life of the LED.

Description

A kind of strip high-power LED street lamp of horizontal fin heat radiation form

Technical field

The invention belongs to the electric lighting technical field, relate to a kind of strip high-power LED street lamp of horizontal fin heat radiation form.

Background technology

LED is as a kind of lighting source of tool potentiality, and its exploitation has become ripe with using, and replacing conventional light source has also become a kind of trend and inevitable; Yet, the energy of LED can transfer to the luminous energy except a part, wherein suitable most still to transfer heat energy to, so, heat dissipation problem remains influences the bottleneck that great power LED is used and developed, so, if design unreasonable manufacturing cost and the energy-saving effect and the service life that will directly have influence on high-power LED lamp.

Current, what high-power LED (Light Emitting Diode) road illuminating lamp adopted mainly is the Natural Heat Convection form of lamp socket and radiating fin integrated design, and the Aspect Ratio of the significant surface of designed light fixture all is confined to less than 2: 1, even less than 5: 3; Say that again what the arrangement mode of radiating fin adopted nearly all is to stretch at the back of light fixture parallel longitudinal; Like this, it almost is a square block that the radiating fin at the light fixture back side distributes, so, virtually just heat energy all concentrated on lamp body in be formed centrally a bigger high temperature piece, heat distribution is very inhomogeneous, thereby the directly normal operation of its led chip on every side of influence distribution, even can't work in the part.Unless enlarge the ratio of lamp body and power, promptly under with the condition of constant power, enlarge lamp body area and radiating fin developed area, like this, still it all is inconsiderable going up consideration safely from cost, because, the design principle of light fixture is farthest to dwindle the ratio of lamp body and power, does forr a short time at following light fixture volume of the power condition that satisfies the use occasion requirement, and quality is lighter.

Summary of the invention

The object of the present invention is to provide a kind of strip high-power LED street lamp of horizontal fin heat radiation form, with its pointed structural design provide a new solution for improving above-mentioned existing problem, thereby help promoting the further application and the development of high-power LED illumination.

For achieving the above object, solution of the present invention is:

A kind of strip high-power LED street lamp of horizontal fin heat radiation form is combined by integrated lamp socket, end stern transom plate, led chip module and light-passing board.

Described integrated lamp socket is made up of lamp socket plate, termination shrouding, mounting sleeve, radiating fin and spine, and integrated design forms with the disposable die casting of aluminum material; Described lamp socket plate is watt shape volume groove of a strip, its positive both sides are the interior curved little circular arc of symmetry, for the cover ledge of light-passing board is installed, the middle part in its front is big cambered surface, is reserved with the screw hole that the led chip module is installed on this cambered surface in the inboard at the edge of two little circular arcs; One spine is arranged in the middle of the back of lamp socket plate, and the plane of radiating fin is vertical with it and vertically evenly distributed in the both sides of spine, and radiating fin is a little more than spine; The one side of described termination shrouding is connected with the lamp socket plate, the center of another side is connected and installed sleeve pipe, also be distributed with grid-like reinforcement rib at this face, strengthen rib and flush along the neighboring of termination shrouding and add some ribs anyhow again in the centre after crowding around and make it into grid-like; Reserve at the center of termination shrouding in addition and lead to the power supply lead wire hole of mounting sleeve inner chamber; Described mounting sleeve is the outer tube that docks with street lamp bracket, and there is the rectangular reinforcement rib of a thickening projection at its back, is reserved with the installation screw hole on this reinforcement rib; Lamp socket plate tail end is reserved with the screw hole of installation end stern transom plate.

Described led chip module is made up of the metal substrate and the led chip of strip, led chip is welded on the substrate, be reserved with installing hole on the substrate, be installed in the positive precalculated position of lamp socket plate with the installation screw, circuit between each substrate connects with the high temperature multi cord, and the general supply lead-in wire is reserved certain-length outside line to be connect after passing the reservation fairlead of integrated lamp socket termination shrouding and mounting sleeve.

Described light-passing board is the plane light-passing board of a monoblock, is made by the printing opacity plastic cement, is placed in the reservation grooving of integrated lamp socket front edge with the mode of being nested.

The installation end face of described end stern transom plate is the plane that is complementary with lamp socket plate tail end, and is reserved with the grooving and the installing hole of the light-passing board that is nested, and its back side is distributed with grid-like reinforcement rib; Be installed on the tail end of integrated lamp socket with the installation screw.

Like this, because light fixture has adopted the lamp socket and the heatsink transverse fin design of rectangular watt of shape volume flute profile, make radiating fin and lamp body in air, have more permeability, improved the radiating effect of light fixture integral body to a great extent, so, the heat energy that is produced by led chip can not cause clustering phenomena yet, thereby helps further improving light efficiency and the service life of LED.

After adopting said structure, the present invention has following progressive advantage:

1, good heat dissipation effect, light weight, resistance is little.

2, simple in structure, compact, firm, easy for installation, practicality.

3, good looking appearance, generous.
