Description

A kind of LED high light torch

Technical field

The utility model relates to a kind of torch, relates in particular to a kind of LED high light torch.

Background technology

LED high light torch is with a kind of novel illumination instrument of light emitting diode (being LED) as light source, has power saving, durable, advantage such as brightness is strong.This torch often is used to the anti-riot special dimension that waits of public security.

The characteristics of LED light-emitting component are exactly at the high heat of minimum volume generation, and the thermal capacity of LED itself is also very little, thus must these heats be conducted with the fastest speed, otherwise will produce very high junction temperature.

The light decay of LED is all directly relevant with its junction temperature with the life-span.The bad junction temperature of dispelling the heat is just high, the life-span is just short.Therefore, existing LED high light torch is employed in the mode of offering increase area of dissipations such as radiating fin in its bowl place more and comes the LED light-emitting component is lowered the temperature.But the excessive volume of head bowl causes the user to use inconvenience, has limited the use occasion of LED high light torch.

The utility model content

The utility model provides the LED high light torch of the good radiating effect of a kind of tool to the drawback of prior art.

The described LED high light of the utility model torch; Comprise the torch head bowl that is provided with the LED light-emitting component; And the torch that is provided with battery and switch element is held tube; Said torch head bowl periphery is coated with the cooling chamber coaming plate, is full of cooling fluid in the cavity space between said cooling chamber coaming plate and the torch head bowl.

In the described LED high light of the utility model torch; Said cooling chamber coaming plate comprises the one-body molded and fixedly coaming plate that extend to torch head bowl top with torch head bowl bottom; And latch closure is in the movable platen at torch head bowl top, and said movable platen is threaded with said fixedly coaming plate.

In the described LED high light of the utility model torch, said fixedly coaming plate and movable platen junction are provided with sealing ring, said movable platen and said fixedly coaming plate is threaded time compressing sealing circle.

In the described LED high light of the utility model torch, said torch head bowl top is provided with sealing ring, and said movable platen latch closure is oppressed the sealing ring when torch head bowl top.

In the described LED high light of the utility model torch, said cooling fluid is cooling water or cold oil.

In the described LED high light of the utility model torch, said movable platen periphery ring is provided with a plurality of juts.

In the described LED high light of the utility model torch, said jut protrudes out along the circumferencial direction radiation of torch head bowl.

In the described LED high light of the utility model torch, said jut protrudes out to the place ahead of torch head bowl.

In the described LED high light of the utility model torch; Through the cooling chamber coaming plate being set, and be full of cooling fluid in the cavity space between this cooling chamber coaming plate and torch head bowl, and then this cooling fluid capable of using is cooled off to the LED light-emitting component as the heat conduction media in torch head bowl periphery; Its cooling effect to the LED light-emitting component is superior to the natural type of cooling of the prior art greatly; Therefore, can significantly reduce the junction temperature of LED element, improve the service life of LED element; And, adopt the LED high light torch volume of the said scheme of the utility model littler, be easy to carry more.

Description of drawings

Fig. 1 is the structural representation of the said LED high light of the utility model torch.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is done further detailed description, can implement according to this with reference to the specification literal to make those skilled in the art.

As shown in Figure 1, the described LED high light of the utility model torch comprises the torch head bowl 1 that is provided with LED light-emitting component 2, and the torch that is provided with battery 4 and switch element 5 is held tube 3.The set inside of said torch head bowl 1 has snoot, and said LED light-emitting component 2 places the optical centre of this snoot; Top at said torch head bowl 1 also is provided with glass plate, with sealing LED light-emitting component 2 residing spaces, prevents that liquid such as moisture from invading to cause LED light-emitting component 2 to cause its damage.Said torch is held tube 3 and is hollow, and its hollow interior space is placed battery 4; The bottom of holding tube 3 at this torch can be provided with switch element 5, and this switch element 5 is controlled the work of LED light-emitting component 2 through the on-off circuit supporting with it or stopped.Said torch is held tube 3 and can be adopted thread connecting mode to be connected with torch head bowl 1.

Periphery at said torch head bowl 1 is coated with cooling chamber coaming plate 7, is full of cooling fluid 8 in the cavity space 6 between said cooling chamber coaming plate 7 and the torch head bowl 1.In the utility model, said cooling fluid 8 can adopt cooling water or cooling wet goods to possess the liquid medium of refrigerating function.

Particularly; Said cooling chamber coaming plate 7 can comprise the one-body molded and fixedly coaming plate 71 that extend to torch head bowl 1 top with torch head bowl 1 bottom; And latch closure is in the movable platen 72 at torch head bowl 1 top, and said movable platen 72 and said fixedly coaming plate 71 are through being threaded.Fixedly coaming plate 71 and the integrated mode in torch head bowl 1 bottom of employing why is to have enough intensity in order to ensure fixing coaming plate 71 on the one hand, can guarantee also that on the other hand fixedly coaming plate 71 and torch head bowl 1 intersection have better sealing; Simultaneously, experience based on manufacturing process and user, adopt above-mentioned one-body molded also be optimal scheme.Said movable platen 72 latch closures are threaded in the top of torch head bowl 1 and with fixing coaming plate 71, itself and fixedly the outer wall of coaming plate 71, torch head bowl 1 formed airtight cavity space, in this airtight cavity space, then be full of cooling fluid 8.Because cooling fluid 8 has good thermal conductivity and flowability, therefore, can the heat that LED light-emitting component 2 in the torch head bowl 1 sends be distributed rapidly.

In the utility model, said movable platen 72 peripheries also can encircle establishes a plurality of juts 73, and said jut 73 both can protrude out along the circumferencial direction radiation of torch head bowl 1, also can protrude out to the place ahead of torch head bowl 1.These juts 73 can make the said LED high light of the utility model torch possess the anti-riot function of seeking survival, for example, when being in the compartment of sealing, these jut 73 crushing window glass capable of using and escaping.

In the utility model; Be provided with sealing ring 11 at said fixedly coaming plate 71 with movable platen 72 junctions; When said fixedly coaming plate 71 is threaded with movable platen 72; Sealing circle 11 is oppressed, and then fills up fixedly coaming plate 71 and space, movable platen 72 junction, prevents that cooling fluid 8 is from this gap accidental release.

In the utility model; Top at torch head bowl 1 is provided with sealing ring 12, and when said movable platen 72 latch closures during in torch head bowl 1 top, said sealing ring 12 is oppressed; And then fill up the space of movable platen 72 and the junction of torch head bowl 1, prevent that cooling fluid 8 from leaking from this gap.

Although the embodiment of the utility model is open as above; But it is not restricted to listed utilization in specification and the embodiment; It can be applied to the field of various suitable the utility model fully, for being familiar with those skilled in the art, can easily realize other modification; Therefore under the universal that does not deviate from claim and equivalency range and limited, the legend that the utility model is not limited to specific details and illustrates here and describe.
