Background technology
Because light emitting diode (LED) has good brightness, long life-span, advantage such as power saving more, is widely used on the indoor or outdoor lighting device by manufacturer at present.Yet, influence the most remarkable factor of LED length in service life, providing these LED can operate under a working environment than thermophilic.Therefore, the inventor is promptly so that the heat radiation of lighting device to be provided, as the research topic of case of the present invention.
A kind of known lighting device is to be provided with insulating barrier and printed circuit thereof in the metal substrate bottom surface, power supply connects a plurality of LED, wherein the LED lighting device connects the heating section of heat pipe in the metal substrate top, and the heat release section of heat pipe is stretched out and is connected on the radiating piece, and radiating piece is located in the opening of lamp stand latter end, carry out heat loss through conduction with contact lamp stand inwall.
This LED lighting device, the heating section of its heat pipe and heat release section are horizontal in the use.When daytime, direct irradiation of sunlight was in lamp stand, heat will heating section and metal substrate through the heat release section of radiating piece, heat pipe, heat pipe after, each LED is given in conduction.Thereby formation makes each LED often be under the high temperature, and significantly shortens its service life the heating of each LED.Inside heat pipe is provided with metal knitted net or sintering metal powder, thereby working fluid is produced the anelasticity that brute force is arranged, and makes working fluid quite slow from the speed that heat release section flows back to heating section, and can't form reverse opening circuit; Really remain improver in addition.
Summary of the invention
A purpose of the present invention; be to provide a kind of lighting device with heat radiation protection loop; the vertical parallax configuration of its heating section by heat pipe and heat release section, and inside heat pipe form many grooves; produced forward conducting and reverse opening circuit; can protect each LED effectively; cross cause thermal damage with the environment of avoiding Yin Gaore, thereby can significantly prolong its service life.
In order to reach above-mentioned purpose; the invention provides a kind of lighting device with heat radiation protection loop; comprise radiator and LED lamp group; this radiator comprises heat-conducting plate, heat pipe and radiator; heat pipe has heating section and reaches the heat release section that is formed with vertical parallax with this heating section; heating section is connected on the heat-conducting plate; form many grooves at this inside heat pipe in addition; groove is communicated with heating section and heat release section; and heating section is formed at the below of heat release section; radiator is connected on the heat release section, and LED lamp group then is connected on the heat-conducting plate.
In sum; heating section and the vertical parallax configuration of heat release section and many grooves of inside heat pipe moulding with lighting device of heat radiation protection loop by heat pipe of the present invention; produced forward conducting and reverse opening circuit; can protect each LED effectively; cross cause thermal damage with the environment of avoiding Yin Gaore, thereby can significantly prolong its service life.

The specific embodiment
Relevant detailed description of the present invention and technology contents, conjunction with figs. is described as follows.Yet institute's accompanying drawing only provides reference and explanation usefulness, is not to be used for the present invention is limited.
Please refer to Figure 1 and Figure 2, it is respectively radiator of the present invention and LED lamp group three-dimensional exploded view and combination appearance figure, the invention provides a kind of lighting device with heat radiation protection loop, and it mainly comprises radiator 1 and LED lamp group 5, wherein:
How much suitably determining of the heat that the quantity of heat pipe 21 can be distributed according to actual needs.Present embodiment is seven heat pipes, it is one and keeps flat " U " shape, upper and lower two mutual parallel parts constitute the heating section 22 and the heat release section 23 of heat pipe 21 respectively, and heating section 22 and heat release section 23 are formed with the difference of high and low position between the two, and heating section 22 is formed on heat release section 23 belows.The heating section 22 of present embodiment is rounded, is embedded in the groove 111 of aforementioned heat-conducting plate 11 in order to part, and is long-pending with the contact surface that enlarges both.In addition, for increasing the closely connected effect of heat-conducting plate 11 and heat pipe 21, can smear the heat-conducting medium (not shown) in its zone that contacts.What specify is, heat release section 23 in this embodiment, though be parallel to heating section 22, yet it will be appreciated by those skilled in the art that heat release section 23 also can be implemented with an angle that raises up a little with heating section 22.
Please refer to Fig. 3 and shown in Figure 4, it is respectively the a-quadrant partial enlarged drawing of assembled sectional view of the present invention and Fig. 3.These heat pipe 21 inside are installed with working fluid 24 and form the continuity grooves 25 that are communicated with heating section 22 and heat release section 23 more, and the axial line setting of these groove 25 parallel heat pipes 21, and are formed with the vacuum cavity volume in heat pipe 21 inside.These heat pipes 21 transmit heat with gaseous state, the liquid variation, so its heat conduction speed is much larger than the heat conduction speed between solid.
Please refer to shown in Figure 5ly, it is a user mode cutaway view of the present invention, and LED lighting device of the present invention can be applied in it outdoor illumination.Make each LED 52 luminous when start LED lamp group 5 at night after, the heat that these LED 52 are produced will be transmitted to the heating section 22 of heat-conducting plate 11 and heat pipe 21 belows successively, and be heated by heat pipe 21 internal work fluids 24 and to become gas evaporation.This boil-off gas will carry a large amount of heat energy and mobile toward heat release section 23 directions of heat pipe 21 tops rapidly, and the heat-conducting seat 32 and the fin 33 of radiator 31 given in conduction again.By these fin 33 with arround gas carry out heat exchanging process and heat dissipation gone out.In addition, utilize the heat release section 23 of fin 33 and heat-conducting seat 32 opposite heat tubes 21 to carry out the continuation heat radiation, can make the generation condensation of heat release section 23 gas inside simultaneously and become liquid, by gravity effect and continuity groove 25, these condensed fluids are flowed back in the heating section 22 of heat pipe 21 belows fast by groove 25.Finishing cold and hot exchange cycles, and present a forward conducting phenomenon.
Otherwise under the situation at sunshine, LED lamp group 5 is closed condition by day, when calorific value that sunshine shines will directly or indirectly be absorbed by each fin 33.These heats will only conduct the heat release section 23 to heat pipe 21 tops, because of the working fluid 24 of heating section 22 inside be subjected to the gravity effect, and the negative angle that produces of heating section 22 configurations of heat pipe 21 concern, can't continue to conduct heating section 22, and present a reverse breaking phenomena to heat pipe 21 belows.Thereby can protect each LED 52 effectively, cross cause thermal damage with the environment of avoiding Yin Gaore, and can significantly prolong its service life.
The foregoing description only supplies explanation the present invention's usefulness, and is not limitation of the present invention.Those skilled in the art under the premise without departing from the spirit and scope of the present invention, the various equivalent structures of being made change all within the scope of the present invention.Protection scope of the present invention is defined by the claims.
