Abstract

The utility model provides an LED (light-emitting diode) radiating tube structure which comprises a bottom plate, a supporting plate for supporting an LED lamp body and a power terminal, and a plurality of radiating branch tubes positioned between the bottom plate and the supporting plate, wherein each radiating branch tube comprises a main body and a plurality of radiating lugs extending outwards from the main body; at least two through convection holes are arranged in the main body; the ends of at least two radiating lugs are respectively provided with a column strip; and the column strip is longer than the main body, so that a radiating space is formed between the upper part and the lower part of the main body between the supporting plate and the bottom plate, thereby achieving the goal of enhancing the radiating efficiency.

Description

LED lamp bar radiating tube body structure

Technical field

The utility model relates to a kind of LED lamp bar radiating tube body structure, and it provides can be effectively and can get rid of the technology of LED heat that lamp produces fast.

Background technology

The employed bulb kind of conventional road lamp before comprises: metal halide lamp, incandescent lamp, high-pressure mercury lamp and province's electric light etc.Annual conventional road lamp propped up according to statistics goes out about more than the 400000000 yuan of RMB of the electricity charge, and each street lamp competent authority all must compile the electricity charge of jumbo budget payment street lamp every year.If all change the street lamp in full court gulf into LED, can save the electricity charge more than 40% according to estimates, energy-saving effect is very considerable.Add the application that cooperates solar module, process the benefit that the solar battery LED street lamp more can be brought into play low-carbon environment-friendly.

LED illumination is a solid-state illumination light source of new generation, has characteristics such as energy-conservation, high efficiency, life-span length, environmental protection, safe, non-thermal radiation.Because solar cell and LED are dc component, need not use frequency converter to do frequency inverted, can avoid efficient conversion loss, so the popularization and the application of high efficiency LED illumination, the arriving of the revolution of throwing light on for the third time meaned.

Yet in the design of high-efficiency LED street lamp, most important is exactly the design of heat radiation.Be provided with gripper shoe between base plate and the gripper shoe, apart from being the cross-ventilation space, reach by base plate and conduct heat and dispel the heat, and this kind heat radiation being the radiating mode that belongs to passive type by following by each other.When especially static no wind regime or cold air get into, from the base plate face reach dispel the heat and cross-ventilated effect limited.Even, make with the upper and lower plates breakthrough form to become heat loss through convection, but still can't effectively improve the efficient of LED lamp body heat radiation with linking with the hollow arm between base plate and gripper shoe.

The utility model content

The purpose of design of the utility model is, a kind of LED lamp bar radiating tube body structure that dispels the heat quick, simple in structure, as to meet economic benefit is provided.

LED lamp bar radiating tube body structure through the utility model can reach the high effect of rate of heat dissipation, and the heat radiation body directly is set below the LED lamp body, and its heat energy is directly dispelled the heat to discharge orifice by space about the body and hollow.

The radiating tube of the LED lamp bar radiating tube body structure of the utility model is external to be arranged with a plurality of lugs, is provided with the post bar at the lug tail end that can support body, makes the post bar be higher than body length.Thus, can make body upper end and gripper shoe and LED lamp body below form a heat-dissipating space, and this heat-dissipating space communicates again with the hollow of body to discharge orifice, can reach the purpose that hot-air is shed by upper and lower thus.

The LED lamp bar radiating tube body structure of the utility model has better radiating efficiency for making body, outwards is provided with a plurality of heat radiation lugs around the body, can body be dispersed in the air heat energy that discharge orifice the conducted face through lug, reaches the purpose of heat radiation.

Fig. 2 representes the three-dimensional embodiment of heat radiation body of the utility model.

Fig. 3 is the plane of the heat radiation body of the utility model.

Description of reference numerals:

11 base plates, 12 gripper shoes

17 heat-dissipating spaces, 20 bodys

23 heat radiation lugs, 24 post bars

25 post bars, 3 power supply terminals

4 LED lamp bodies

The specific embodiment

The LED lamp bar radiating tube body structure of the utility model, as shown in Figure 1, LED lamp bar at least by base plate 11, be used to support LED lamp body 4 and power supply terminal 3 gripper shoe 12, and 20 of the bodys of a plurality of supports between base plate 11 and gripper shoe 12 form.Wherein, this heat radiation body 20 is positioned at the below of LED lamp body 4 positions of gripper shoe 12.

With reference to shown in Figure 3; These heat radiator body 20 peripheries are provided with the lug 23 of a plurality of heat radiations; Can support body 20 and make its firm position be provided with post bar 24, be four post bars 24 shown in the figure, and this post bar 24 is located at the outer end of lug 23; And post bar 24 highly is longer than body 20 length, makes body form a heat-dissipating space 17 about in the of 20 and between gripper shoe 12 and the base plate 11.

Therefore; The heat of LED lamp body 4 will directly import body 20 into; Heat conduction through central rods 25 reaches heat-dissipating space 17 and makes cold air take away heat, and by the heat radiation lug 23 more air contact area that produces; Can the heat energy of conduction be spread out of by lug 23, and can reach high efficiency radiating effect.

In sum, the LED lamp bar radiating tube body structure simple structure of the utility model, radiating efficiency is high, genuine improvement the not good problem of traditional heat-dissipating.
