Abstract

The utility model relates to a fishing lamp capable of reducing light loss. The fishing lamp comprises a drum body, a light source system and a light gathering system, wherein the light source system is composed of light sources, and the light gathering system corresponds to the light sources. The light source system comprises at least three light sources, the light gathering system comprises at least two lenses arranged coaxially, and the diameters of the lenses are sequentially increased according to the distance from being near to the light sources to being far away from the light sources. Due to the fact that a plurality of lenses are arranged, light can be focused many times, the light loss is reduced, and irradiation brightness is improved.

Description

Can reduce the fishing lamp of light losing

Technical field

The utility model relates to a kind of fishing lamp, especially a kind of fishing lamp that reduces light losing.

Background technology

The Lights section of present fishing lamp (lamp using during fishing) is similar with common flashlight, comprises stack shell, cylinder head, light source, and lens are contained in cylinder head above, and light source is generally LED lamp, and the light that light source sends throws light on by the lens focus on cylinder head.The light of this fishing lamp light source transmitting has lost a part in optical collector, cannot be fully utilized, so irradiation brightness is not high.

In view of this, special the utility model that proposes.

Utility model content

The purpose of this utility model is to provide a kind of fishing lamp that reduces light losing.

For solving the problems of the technologies described above, the utility model adopts the basic conception of technical scheme to be:

A kind of fishing lamp that reduces light losing, comprise stack shell, the light-source system being formed by light source and the condenser system corresponding with described light source, described light-source system comprises at least three light sources, described condenser system comprises at least two lens of coaxial setting, according to the described light source of distance order lens diameter from the close-by examples to those far off, increases successively.

Preferably, in described condenser system, described in distance, light source outer layer lens is farthest the moving lens adjustable with described light source distance.

Preferably, it is upper that described outer layer lens is contained in cylinder head, between described cylinder head and described stack shell, is threaded.

Or it is upper that described outer layer lens is contained in cylinder head, socket connection between described cylinder head and described stack shell.

Preferably, the lens in described condenser system except described outer layer lens are inner-layer lenses, and described inner-layer lenses is the fixed lens fixing with described light source distance.

Described condenser system can comprise an outer layer lens and an inner-layer lenses.

Described light source can be three, four or five.

When described light source is four, preferred, four described light sources at the optically focused center of lens according to 2*2 matrix arrangements.

The beneficial effects of the utility model are: the utility model is owing to being provided with a plurality of lens, and light can multi-focusing, thereby have reduced the loss of light, improve irradiation brightness.

The specific embodiment

In order to make those skilled in the art person understand better the utility model scheme, below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.

With reference to Fig. 1, the utility model is a kind of fishing lamp that reduces light losing, comprise that stack shell 1, the light-source system being comprised of light source and the condenser system corresponding with described light source, described light-source system comprise at least three light sources, described condenser system comprises at least two lens of coaxial setting, according to the described light source of distance order lens diameter from the close-by examples to those far off, increases successively.

Owing to being provided with a plurality of lens, light can multi-focusing, thereby has reduced the loss of light, improves irradiation brightness.

Introduce the specific embodiment of a kind of three light sources, two lens below.

Referring to Fig. 1, in three light source 3(the present embodiment, adopt LED lamp, in Fig. 1, Fig. 2 not shown the 3rd) be contained on the circuit board 2 in stack shell 1.In described condenser system, described in distance, light source outer layer lens 6 far away is the moving lens adjustable with described light source 3 distances, and concrete structure is: described outer layer lens 6 is contained on cylinder 4, and (not shown) is threaded between described cylinder 4 and described stack shell 1.The inner-layer lenses 5 and the circuit board 2 that approach described light source 3 are fixed together, for and described stack shell 1 between the fixing fixed lens (inner-layer lenses 5 also can be fixed on other places) of distance.Described circuit board is preferably heat sink.

With reference to Fig. 2, when light source 3 is luminous, light light source 3 being sent by inner-layer lenses 5 is assembled (conventionally below 90 °), improves the service efficiency of light source.Inner-layer lenses 5 is because of near apart from light source 3, most of light can be polymerized to 90 ° of angles with interior light beam, impinges upon on outer layer lens 6 by its optically focused for the second time, reaches the object of long drive.Owing to being provided with double layer lens, light can multi-focusing (with reference to Fig. 2), has reduced the loss of light, has improved irradiation brightness, and can realize optically focused and astigmatic different radiation responses.

Or described outer layer lens 6 is contained on cylinder 4, socket connection between described cylinder 4 and described stack shell 1.

Lens can be for a plurality of, a plurality of lens in the manner described above described light source of distance outer layer lens are farthest set to moving lens, and other inner-layer lenses are set to fixed lens, but more times focusing of a plurality of lens, further reduce light losing, improve irradiation brightness.The light source 3 of condenser system can also be for four or five, and when light source is four, four described light sources 3 are at the optically focused center of lens according to 2*2 matrix arrangements, and this is convenient to light source 3 to concentrate, and prevents that light from cannot project on lens, causes light losing.

The above is only preferred embodiment of the present utility model; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
