Abstract
The utility model relates to an LED (light-emitting diode) tunnel lamp which comprises an LED substrate, a heat dissipation base and an end, wherein the LED substrate is pasted on the front surface of the heat dissipation base; the end is connected to two ends of the heat dissipation base and the LED substrate; the middle of the back of the heat dissipation base is provided with a hollow channel; and fins having different heights are arranged on both sides of the channel. According to the LED tunnel lamp, since the middle of the back of the heat dissipation base is provided with the hollow channel and fins having different heights are arranged on both sides of the channel, not only the contact area between the back of the heat dissipation base and the air is enlarged, but also the air flow at the back of the heat dissipation base is enhanced through the hollow channel and the fins having different heights, so that the heat dissipation of the heat dissipation base is quickened, the heat dissipation efficiency is improved and the service life of the LED tunnel lamp is prolonged.
Description
Technical field
The utility model relates to the LED lighting field, particularly a kind of LED Tunnel Lamp.
Background technology
LED (LightingEmittingDiode) illumination promptly is a led lighting, is a kind of semiconductor solid luminescence device.It is to utilize the solid semiconductor chip as luminescent material, in semiconductor, through carrier compound energy of emitting surplus takes place and causes photo emissions, directly sends red, yellow, blue, green, blue or green, orange, purple, white light; The LED illuminating product utilizes LED as the produced ligthing paraphernalia of light source exactly.The LED illuminating product has that volume is little, power consumption is low, long service life, advantage such as environmental and durable, be called as the 4th generation lighting source or green light source, therefore obtain extensive use.At present, LED lamp group also is used to the tunnel illumination is provided, i.e. the LED Tunnel Lamp.Because LED Tunnel Lamp power is bigger, can produce great amount of heat during its work, the temperature of LED lamp group can be higher, and therefore, the LED Tunnel Lamp needs stronger radiating effect.But in the prior art, the radiating effect of LED Tunnel Lamp is unsatisfactory, causes reduce its service life, therefore, is necessary to make improvements.
The utility model content
The problem that the utility model solves provides a kind of LED Tunnel Lamp, solves existing LED Tunnel Lamp radiating effect difference and causes short problem in service life.
For addressing the above problem, the technical scheme that the utility model adopts is:
A kind of LED Tunnel Lamp; Comprise LED substrate, radiating seat, termination, it is positive that said LED substrate is attached at said radiating seat, and said termination is connected in said radiating seat and LED substrate two ends; Be provided with hollow channel in the middle of the said radiating seat back side, said passage both sides is provided with the fin that height differs.
Further, the height of said fin becomes big by both sides, the said radiating seat back side to the centre gradually.
Further, the height of said fin is diminished to the centre by both sides, the said radiating seat back side gradually.
Further, said channel cross-section is a polygon.
Further, said channel inner surface is provided with lug, nib, does not contact each other between the said lug, nib.
Further, the positive both sides of said radiating seat are provided with wall, and said wall arranged outside has many arris.
Compared with prior art, the advantage of the utility model technical scheme is:
Through radiating seat being arranged to have hollow channel in the middle of the back side; Said passage both sides is provided with the fin that differs of height, has not only increased the contact area of the radiating seat back side and air, and hollow channel and the fin that just differs; The air that has strengthened the radiating seat back side flows; Thereby quickened the heat radiation of radiating seat, improved radiating efficiency, prolonged the service life of LED Tunnel Lamp.
Description of drawings
Fig. 1 is the utility model specific embodiment sketch map.
The specific embodiment
Elaborate below in conjunction with the specific embodiment of accompanying drawing to the utility model.
Fig. 1 is the utility model specific embodiment sketch map.As shown in Figure 1, a kind of LED Tunnel Lamp comprises LED substrate (not shown), radiating seat 1, termination 2, and said LED substrate is attached at said radiating seat 1 front 11, and 2 of said terminations are connected in said radiating seat 1 and LED substrate two ends.
Be provided with the passage 121 of hollow in the middle of said radiating seat 1 back side 12, said passage 121 both sides are provided with the fin 122 that height differs.
The height of said fin 122 is become big gradually or diminishes to the centre by 12 both sides, said radiating seat 1 back side all can; The fin 122 that height differs is provided with, and helps flowing of fin 122 surperficial air, thereby strengthens thermolysis.
The cross section of said passage 121 is a polygon, like triangle or quadrangle, in addition pentagon, preferred quadrangle; Said passage 121 inner surfaces are provided with lug, nib 1211; One lug, nib 1211 can be set on each face also many lug, nibs 1211 can be set; Purpose is the contact area that increases heat radiation position and air; Consider the air flow field problem in the passage 121 simultaneously, lug, nib 1211 is generally each face and is provided with one, and does not contact each other between the different lug, nib 1211.This structure Design makes air can form convection channel, accelerates it and flows, and take away the heat on lug, nib 1211 surfaces, thereby improve radiating effect.
Said radiating seat 1 positive both sides are provided with wall 111, and said wall 111 outsides then are provided with many arris 1111, and purpose also is in order to increase the contact area of radiating seat 1 and air, to improve radiating effect.
The described LED Tunnel Lamp of the utility model specific embodiment, through radiating seat being arranged to have hollow channel in the middle of the back side, said passage both sides is provided with the fin that height differs; Not only increased the contact area of the radiating seat back side and air; And hollow channel and the fin that differs of height, the air that has strengthened the radiating seat back side flows, thereby has quickened the heat radiation of radiating seat; Improve radiating efficiency, prolong the service life of LED Tunnel Lamp.
Though the utility model with preferred embodiment openly as above; But it is not to be used for limiting the utility model; Any those skilled in the art are in spirit that does not break away from the utility model and scope; Can make possible change and modification, so the protection domain of the utility model should be as the criterion with the scope that the utility model claim is defined.
