Abstract

The utility model discloses a vertical heat conducting LED streetlamp, which comprises a lamp base and a modular LED lamp group. Two ends of the modular LED lamp group are fixed to two sides of the lamp base respectively; the bottom surface of the lamp base is hollowed out; and the modular LED lamp group is exposed from the bottom surface of the lamp base. Therefore, when the LED streetlamp works, a radiator positioned at the top of the modular LED lamp group absorbs heat of LED chips and upwardly conducts the heat out, air above the modular LED lamp group upwardly flows after absorbing the heat and flows to the outside of the LED streetlamp through radiating holes of a protective cover, cold air below the modular LED lamp group is supplemented into the LED streetlamp to form convection air, and radiating of the LED streetlamp is accelerated. The modular LED lamp group is exposed from the bottom surface of the lamp base, and the lamp base does not shade light of the modular LED lamp group, so that the LED streetlamp has a larger illumination range.

Description

A kind of vertical heat transfer formula LED street lamp

Technical field

The utility model relates to the street lamp technical field, refers in particular to a kind of vertical heat transfer formula LED street lamp.

Background technology

In the prior art, along with the maturation of LED technology, LED begins to be widely used in every field; Street lamp is also brought into use the LED street lamp, and the LED street lamp of prior art comprises LED lamp group, power module, lamp socket, guard shield and light permeable protection, and LED lamp group and power module are fixed in lamp socket; Guard shield is fixed in the lamp socket end face, and light permeable protection is fixed in the lamp socket bottom surface, and guard shield and light permeable protection seal the whole LED street lamp; The heat that LED lamp group and power module produce in the course of the work is difficult to conduct; In addition, LED lamp group and light permeable protection have certain distance, and LED lamp group is to be arranged at the inner position of LED street lamp; The part light that LED lamp group is sent receives stopping of lamp socket and light permeable protection, and the illumination zone of LED street lamp is less.Therefore, the LED street lamp of prior art has improved needs.

The utility model content

The purpose of the utility model is that the deficiency to prior art provides a kind of vertical heat transfer formula LED street lamp, and LED street lighting scope is big, and the LED street lamp dispels the heat through the vertical heat transfer mode, forms the convection current air in the heat radiation process, and radiating rate is fast.

For realizing above-mentioned purpose, the utility model is realized through following technical scheme:

A kind of vertical heat transfer formula LED street lamp comprises lamp socket and module type LED lamp group, and the two ends of module type LED lamp group are individually fixed in the lamp socket both sides, the bottom surface hollow out of lamp socket, and module type LED lamp group is exposed from the bottom surface of lamp socket.

Said module type LED lamp group comprises light transmission piece, led chip and radiator; Led chip is fixed in the radiator bottom surface; Light transmission piece is fixed in the radiator bottom surface, and with the sealing of radiator bottom surface, led chip is accommodated in the seal cavity of light transmission piece and the formation of radiator bottom surface around the light transmission piece.

The middle front part of said lamp socket is provided with the rectangle framework, and module type LED lamp group is arranged in the rectangle framework, and the biside plate of rectangle framework is fixed at the two ends of module type LED lamp group.

Said lamp socket is provided with guard shield, and the end face or the front end face of guard shield offer louvre.

Said LED street lamp also comprises power module and electric connection line, and power module is fixed in the lamp socket afterbody, and electric connection line one end connects led chip, the other end connects power module.

The beneficial effect that the utility model has owing to the employing technique scheme: the module type LED lamp group of the utility model is exposed from the bottom surface of lamp socket; When the LED street lamp is worked; The heat that is positioned at the radiator absorption led chip at module type LED lamp group top also upwards conducts this heat, flows to the top behind the absorption of air heat of module type LED lamp group top, and flows to outside the LED street lamp through the louvre of guard shield; The cold air of module type LED lamp group below then adds in the LED street lamp; Form the convection current air, accelerate the radiating rate of LED street lamp, module type LED lamp group is exposed from the bottom surface of lamp socket; Lamp socket does not block the light of module type LED lamp group, makes the LED street lamp have bigger illumination zone.

The specific embodiment

The embodiment of a kind of vertical heat transfer formula LED street lamp of the utility model is shown in Fig. 1 to 3; Comprise lamp socket 1 and module type LED lamp group 2; The two ends of module type LED lamp group 2 are individually fixed in lamp socket 1 both sides, the bottom surface hollow out of lamp socket 1, and module type LED lamp group 2 is exposed from the bottom surface of lamp socket 1.

Module type LED lamp group 2 comprises light transmission piece 3, led chip and radiator 4; Led chip is fixed in radiator 4 bottom surfaces; Light transmission piece 3 is fixed in radiator 4 bottom surfaces, and with the sealing of radiator 4 bottom surfaces, led chip is accommodated in the seal cavity of light transmission piece 3 and the formation of radiator 4 bottom surfaces around the light transmission piece 3.Module type LED lamp group 2 is an integrated component, has good performance of heat dissipation and water resistance.The heat radiation of LED street lamp is a vertical heat transfer, and radiating rate is fast.

The LED street lamp also comprises power module 6 and electric connection line, and power module 6 is selected the power module 6 with water resistance for use, and power module 6 is fixed in lamp socket 1 afterbody, and electric connection line one end connects led chip, the other end connects power module 6.

The middle front part of lamp socket 1 is provided with the rectangle framework, and module type LED lamp group 2 is arranged in the rectangle framework, and the biside plate of rectangle framework is fixed at the two ends of module type LED lamp group 2.

For protection module type LED lamp group 2, avoid leaf, dust, foreign material etc. to drop on module type LED lamp group 2, can also be provided with guard shield 5 by lamp socket 1, the end face or the front end face of guard shield 5 offer louvre.

The LED street lamp of the utility model does not need in lamp socket 1 bottom surface light permeable protection 5 to be set in addition; Module type LED lamp group 2 is exposed from the bottom surface of lamp socket 1, and when the LED street lamp was worked, the heat that is positioned at the radiator 4 absorption led chips at module type LED lamp group 2 tops also upwards conducted this heat; Flow to the top behind the absorption of air heat of module type LED lamp group 2 tops; And flow to outside the LED street lamp through the louvre of guard shield 5, the cold air of module type LED lamp group 2 belows then adds in the LED street lamp, forms the convection current air in vertical direction; Accelerate the radiating rate of LED street lamp, improve the luminous efficiency of module type LED lamp group 2.
