Description
Technical field
The utility model is related to a kind of LED flashlights of good heat dissipation effect.
Background technology
With the development of technology, small, power consumptive province LED light emitting diodes have generated；It is compared with incandescent lamp, LED
The advantage of flashlight is that the service life of lamp and battery is generally longer, this is largely due to their power consumption and fortune
Trip temperature is all relatively low.But, under normal circumstances, beam intensity of the beam intensity of LED flashlight than ordinary incandescent lamp flashlight
It is low.The light beam that typical LED flashlight generates is wide and out-focus or center are the higher small luminous point of intensity, and surrounding is width
And the lower hot spot of intensity.
A kind of LED flashlight of good heat dissipation effect of Publication No. 102927452, including switch, LED light, reflective mirror, hand
Handle and translucent cover, multiple LED light are arranged in handle front end, the focus of reflective mirror；Each LED light is connected to by way of in parallel
On power supply in handle；The concavees lens using reversibility of optical path that there are one the centers of the translucent cover is adapted with LED light,
Multiple convex lens are distributed around concavees lens.
But the equipment has ignored LED flashlight when in use, heat can not distribute in time so that LED flashlight temperature
It is higher so that LED flashlight is easily damaged.
Utility model content
In view of this, the utility model aim is to provide a kind of LED flashlight of good heat dissipation effect, it can make internal production
Heat amount distributes in time, good heat dispersion performance.
In order to solve the above-mentioned technical problem, the technical solution of the utility model is：A kind of LED flashlight of good heat dissipation effect
Cylinder, including handle, and lamp cap that is in handle right end and being fixedly connected with handle is arranged are provided with and handle in the lamp cap
LED light being fixedly connected, for illumination, the handle left end are provided with the rear cover being connect with handle, and the rear cover bottom is set
The small-sized fans being connect with rear cover are equipped with, heat dissipation channel is provided in the handle, the handle surfaces are provided with logical with heat dissipation
The tail end of the ventilation hole that road is connected, the heat dissipation channel is connected with rear cover.
Preferably, the heat dissipation channel is provided with more than one and is uniformly distributed centered on handle.
Preferably, the ventilation hole is located on the periphery wall of handle and close to lamp head.
Preferably, the ventilation hole is provided with more than one and is uniformly distributed centered on handle.
Preferably, the base surface is provided with the concavees lens to fit with lamp cap, it is arranged around the concavees lens
There is the convex lens to fit with lamp cap.
Preferably, the rear end of the rear cover is provided with the protection board being fixedly connected with rear cover, the protection plate surface is set
It is equipped with through-hole.
The utility model has the technical effect that following aspect：Due to being provided with small-sized fans, heat dissipation channel and leading to
The wind of air holes, small-sized fans blowout is finally discharged to by ventilation hole in air, wind is by heat dissipation channel by heat dissipation channel
While, handle can be generated in heat be discharged into air together with the wind, to avoid LED flashlight because of temperature mistake
It is damaged when high.
Description of the drawings
Fig. 1 is a kind of structural schematic diagram of the LED flashlight of good heat dissipation effect of the utility model.
Specific implementation mode
Below in conjunction with attached drawing 1, specific embodiment of the present utility model is described in further detail, so that the utility model skill
Art scheme is more readily understood and grasps.
In the present embodiment, it is to be understood that term " centre ", "upper", "lower", " top ", " right side ", " left end ",
" top ", " back side ", " middle part ", etc. instructions orientation or positional relationship be based on the orientation or positional relationship shown in the drawings, only
It is of the invention for ease of description, does not indicate or imply the indicated device or element must have a particular orientation, with spy
Fixed azimuth configuration and operation, therefore be not considered as limiting the invention.
In addition, the connection between component or fixed form if not otherwise specified in this embodiment, connection or solid
Determine mode can be fixed by bolt commonly used in the prior art or pin fix or axis pin connection etc. modes, therefore, this
It is not described in detail in embodiment.
A kind of LED flashlight of good heat dissipation effect, as shown in Figure 1, a kind of LED flashlight of good heat dissipation effect, including hand
