Abstract
The utility model discloses a novel mine lamp which comprises a main lamp LED, a reflector, a convex lens, a cover of a lamp cap and a lamp base of the mine lamp, wherein a control circuit board is arranged in the lamp base; the main lamp LED is arranged on the control circuit board; an aluminum heat distribution board is also arranged between the control circuit board and the main lamp LED; the reflector is arranged in front of the main lamp LED; the convex lens is arranged on the upper part of the reflector; the cover of the lamp cap us fixed on the lamp base through screw threads, wherein the convex lens is a double convex lens. The utility model uses the combination of a single high-energy LED, the double convex lens and the reflector for forming an optical light-gathering structure; therefore, the central light-gathering intensity of the mine lamp is improved; the problem of the central light-gathering intensity of the mine lamp is solved and remote illumination is realized; the illumination intensity requirements in the sub-light regions of the light rays for passing light illumination of the mine lamp are improved; the illumination intensity in the highlight regions is equal to or more than 1000Lx. Simultaneously, the utility model avoids the black circles which appear in the sub-light regions of the light rays for passing light illumination of the mine lamp and the illumination intensity requirements of the light rays in the 120 DEG scattered light regions for passing light can be realized.
Description
Technical field
The utility model relates to a kind of mine lamp.
Background technology
Mine lamp is miner's one of employed necessary tool in underground mine.General main king light, reflector and the convex lens of comprising of present employed mine lamp, convex lens can amplify the reverberation of king light, to reach the purpose of irradiation as far as possible on a large scale.Yet the problem of the center optically focused insufficient strength of mine lamp can appear in this structure usually, therefore just is not easy to see clearly for object far away.
The utility model content
At the problem of above-mentioned existence, the purpose of this utility model is to provide a kind of novel miner's lamp, can improve the center optically focused intensity of mine lamp greatly, thereby realizes far away the photograph.
For achieving the above object, a kind of novel miner's lamp of the utility model comprises: king light LED, reflector, convex lens, lamp holder lid and mine lamp lamp socket, be provided with control circuit board in the described lamp socket, described king light LED is arranged on this control circuit board, between described control circuit board and king light LED, also be provided with the aluminium heat sink, before described reflector was arranged on described king light LED, described convex lens were arranged on described reflector top, and described lamp holder lid is fixed on the described lamp socket by screw thread; Wherein, described convex lens are biconvex lens.
Further, the focal length of described biconvex lens closes and to be: is 17～23: 26～33 near the focal length of described king light LED with ratio away from the focal length of described king light LED.
Further, described ratio is preferably 20: 29.
The utility model adopts single high-energy LED, biconvex lens and reflector combination, constitute an optical concentration structure, improve the center optically focused intensity of mine lamp, the center optically focused strength problem that has solved mine lamp has been realized photograph far away, increase mine lamp dipped beam irradiation light Ya Guang district illumination requirement, highlights illumination 〉=1000Lx (beginning of lighting a lamp, 1 meter distance), also avoid mine lamp dipped beam irradiation light Ya Guang district black circle to occur simultaneously, realized 120 degree left and right sides dipped beam area of scattered light light illumination requirement.
Description of drawings
Fig. 1 is the utility model structural representation.
Light distribution schematic diagram when Fig. 2 uses for the utility model.
The specific embodiment
As shown in Figure 1, the utility model comprises: king light LED4, reflector 3, convex lens 2, lamp holder lid 1 and mine lamp lamp socket 7, be provided with control circuit board 6 in the lamp socket 7, king light LED4 is arranged on the control circuit board 6, between control circuit board 6 and king light LED4, also be provided with aluminium heat sink 5, before reflector 3 was arranged on king light LED4, convex lens 2 were arranged on reflector 3 tops, and lamp holder lid 1 is fixed on the lamp socket 7 by screw thread; Wherein, convex lens 2 are biconvex lens, are respectively 20mm and 29mm near the focal length of king light LED4 and focal length away from king light LED4, and king light LED4 and control circuit board 6 are by a lithium battery 8 power supplies.
During use, as shown in Figure 2, the metope 1 meter of distance after the biconvex lens refraction of the light in the king light LED80 degree scope becomes diameter 120mm highlights.Highlights illumination 〉=1000Lx (beginning of lighting a lamp, 1 meter distance) has also avoided mine lamp dipped beam irradiation light Ya Guang district black circle to occur simultaneously, has realized 120 degree left and right sides dipped beam area of scattered light light illumination requirement.
In addition, the focal length ratio of the utility model biconvex lens can be according to 17～23: 26～33 suitably select.
Claims (3)
