Abstract
The utility model relates to an LED electric torch which comprises a casing, a switch, one or more than one LED luminophor and a power supply device, wherein each LED luminophor is corresponding to a lens which is used for light condensation. The appearance of the lens can be made into a reverse U shape, and the lens can be covered on the LED luminophor, the top of the lens is designed into a two-sided convex lens, light which is respectively emitted by the single LED luminophor is condensed and thus an admirable lighting effect is generated. Compared with a common LED electric torch, the electric torch of the utility model has the advantages of electricity saving and durability.
Description
Technical field
The utility model relates to a kind of flashlight, and referring in particular to a kind of is the flashlight of light source with the LED light emitting diode.
Background technology
Traditional flashlight structure, although appearance and modeling has nothing in common with each other, but structural detail basically is made up of a cylindrical shell and a body that includes light source (as small electric bulb or bulb) that is used for holding battery, have in the body and be designed to bowl-shape reflector, play the effect of optically focused, but the shortcoming of traditional flashlight is that power consumption of the bulb utmost point and service life are not long.Though and existing be the deficiency that the LED flashlight of light source can overcome traditional flashlight with the LED light emitting diode, accomplish power saving, durable, but because the luminous pipe of LED direct projection emitting characteristics forward, even the electric power setting of replacement bulb is the LED luminous tube more than ten nearly, but it is also bad that these light see through the spotlight effect of planar transparent glass, therefore brightness is not good enough, does not reach desirable illuminating effect.
Summary of the invention
Technical problem to be solved in the utility model be provide a kind of brightness significantly to improve at above-mentioned prior art present situation, illuminating effect is splendid, power saving, more durable LED flashlight.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: this high-brightness LED flashlight, comprise housing, switch, LED illuminator and the battery of existing LED flashlight structure, it is characterized in that the equal correspondence of each LED illuminator is provided with the lens that an optically focused is used.
The profile of described lens can be made down " U " shape, and to cover on outside the LED illuminator, its top then is designed to lenticular lens, and single led illuminator issued light optically focused is produced splendid illuminating effect.
Described lens can fix with the wiring board of fixed L ED illuminator.
Described housing can be designed to four sections, is combined by head, middle part, main body, afterbody four parts.
Compared with prior art, advantage of the present utility model is: the utility model is by being provided with the optical lens that an optically focused is used to each LED illuminator, makes the light optically focused that the LED illuminator sends and produces splendid illuminating effect; Simultaneously owing to significantly improved the brightness (overall brightness reaches original twenties times) of the light that each LED illuminator sends, therefore flashlight of the present utility model can obviously reduce the number of LED illuminator, thereby than common more power saving of LED flashlight, durable (can reach ten ten thousand hour under the normal operating position service life of LED, be ten times and even tens times of other light source life), can prolong the service time of battery greatly, reduce the generation that takes gurry, reach good environmental-protection function; The shell of flashlight of the present utility model adopts the four-part form design, except the mounting or dismounting that are beneficial to lens, and has made things convenient for the machining of product, makes product surface smoothly smooth and easy.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is the schematic perspective view of the assembled relation between reflection lens, illuminator and wiring board.
The specific embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
Please refer to Fig. 1, Fig. 2, the utility model flashlight mainly comprise flashlight housing 1, switch 2, several LED illuminators 4, with the lens 5 of illuminator equivalent and battery pack 8 etc., its middle shell 1 has changed syllogic (head, main body, the afterbody) design of conventional aluminium alloy flashlight, adopted the four-part form design of being formed by head 11, middle part 12, main body 13 and afterbody 14, interior battery 8, LED illuminator 4, wiring board 3, planar transparent glass 6 and the annular ring 7 etc. of holding.It not only can make things convenient for the machining of product, and helps the setting of lens.Four LED illuminators 4 are fixed on the wiring board 3, and each LED illuminator 4 all is covered with lens 5 that fix with wiring board 3.Lens 5 are a working of plastics, and its profile is down " U " shape, and top design becomes lenticular lens 51, and pin 52 is arranged at the bottom, can insert in the jack 31 of wiring board.Described each lens 5 promptly insert in the corresponding jack 31 of wiring board by the pin on it 52, and are fixed on the wiring board 3, thereby dismounting is very convenient.Each lens can strengthen the brightness of light with the LED illuminator issued light optically focused of correspondence.This flashlight is by these four lens, and the light that four LED illuminators are sent can reach original twenties times brightness.
Except the structure shown in the foregoing description, the utility model also can have multiple conversion and remodeling, and not only be confined to the concrete structure of above-mentioned embodiment, also can make the integrative-structure that the bottom is connected together as described four the separate lens of present embodiment, the profile of lens also can have various variations; And the quantity of LED illuminator also can increase and can subtract as required, is not limited to four of present embodiment.
Claims (6)
1, a kind of high-brightness LED flashlight, comprise housing (1), switch (2), LED illuminator (4) and battery (8), it is characterized in that: described LED illuminator (4) is one or more, and the equal correspondence of each LED illuminator is provided with the lens (5) that optically focused is used.
2, LED flashlight as claimed in claim 1 is characterized in that: described each lens (5) all are " U " shape that LED illuminator (4) can be covered within it, and lenticular lens (51) structure is made at the top.
