The LED illuminating device disclosed by the invention can improve the heat radiation performance of a street lamp, prolong the service life of the street lamp, simultaneously facilitate mounting and detachment and reduce processing cost.

Description

The LED lighting device

Technical field

The present invention relates to a kind of LED lighting device, relate in particular to a kind of halberd shape LED lighting device.

Background technology

The LED lamp that uses in the market mainly contains lamp socket and illuminating module forms, lamp socket is general to adopt straight section bar to be made, what a plurality of illuminating module were orderly is arranged in the lamp socket, illuminating module is mainly by fin, the several critical pieces of luminous plaque and LGP consist of, whole LED street lamp mainly relies on the fin of illuminating module to dispel the heat, because illuminating module is in the confined space of section bar lamp socket, the tight fin that relies on comes radiating effect and bad, affect the service life of LED street lamp, illuminating module all is to be installed in the lamp socket rigidly in the past in addition, installation and removal are all inconvenient, and the consumptive material that the LED street lamp is made is higher.

Summary of the invention

The object of the invention is to overcome above-mentioned deficiency, a kind of LED lighting device is provided, improve heat dispersion, prolong the service life of street lamp, can be easy for installation and removal simultaneously, cut down finished cost.

The object of the present invention is achieved like this: a kind of LED lighting device, it comprises lamp holder section bar and illuminating module, described lamp holder section bar adopts and makes with the aluminium section bar of radian, described lamp holder section bar adopts the front main air duct, auxiliary air channel, the back side and intermediate cavity structure, described illuminating module is fixed in the main air duct of lamp holder section bar, both sides at described lamp holder section bar are provided with end socket, have a plurality of air vents at described end socket, described illuminating module comprises fin from top to bottom, sealing gasket, luminous plaque and LGP, described sealing gasket and luminous plaque are pressed in the LGP, the mutual clamping of described LGP and fin.

Periphery in described illuminating module is provided with shell fragment.

Compared with prior art, the invention has the beneficial effects as follows:

Utilization of the present invention with the aluminium section bar of radian (squeeze curved during production or produce after bending) as the matrix installed part of lamp module, utilize the form formation of structure of section bar itself with the Cooling Solution of Duct design, street lamp illuminating module itself is straight simultaneously, play installation cushioning effect and the adjustment of slide rail flexibility ratio by top shell fragment design, be convenient to installation and removal, in addition since the size of halberd shape street lamp less than in the past LED street lamp, and connector also reduces, and can reduce production cost.

The specific embodiment

Referring to Fig. 1-Fig. 4, the present invention relates to a kind of LED lighting device, it comprises lamp holder section bar 1 and six groups of illuminating module 2, described lamp holder section bar 1 adopts to be made with the aluminium section bar of radian, described lamp holder section bar 1 adopts front main air duct 1.1, auxiliary air channel 1.2, the back side and intermediate cavity 1.3 structures, not only save material but also can improve radiating effect, described six groups of illuminating module 2 are fixed in the first half of main air duct 1.1 by screw, transformer 12 is installed in the latter half of described main air duct 1.1, and lower part is by baffle plate 13 sealings, be provided with end socket 3 in the both sides of described lamp holder section bar 1, have a plurality of air vents at described end socket 3;

Described illuminating module 2 comprises fin 4, sealing gasket 5, luminous plaque 6 and LGP 7 from top to bottom successively, described luminous plaque 6 comprises aluminium base 8, pcb board 9 and LED particle 10, described aluminium base 8 is arranged at the back side of pcb board 9, described LED particle 10 is evenly distributed on the front of pcb board 9, scribble the thermal conductive silicon glue-line with heat conduction at the back side of described aluminium base 8, described sealing gasket 5 and luminous plaque 6 are pressed in the LGP 7, scribble Waterproof glue line to guarantee the waterproof of luminous plaque 6, described LGP 7 and fin 4 mutual clampings at described sealing gasket 5;

Setting up and down at the edge of described fin 4 have a shell fragment 11, reduce on the one hand to install friction, can remedy the fit-up gap on the other hand, described shell fragment 11 can be arranged at the optional position of illuminating module 2 peripheries, this halberd shape street lamp is divided into two kinds of vertical installation and horizontal installations, when adopting vertical installation, the end socket 3 of lamp holder lower end is removed, the lamp holder fixture is installed, is linked to each other with lamp stand by the lamp holder fixture; When adopting horizontal installation, at the back side of lamp holder section bar 1 the lamp holder fixture is installed, is fixed with lamp stand again.
