Abstract
The utility model discloses a multi-point focusing large-power LED signal lamp display device. An aluminum alloy heat radiation board is arranged at a focus plane of a plurality of optical lenses in a casing; a plurality of LED light sources are uniformly distributed on the heat radiation board; a lamp shade formed by the plurality of optical lenses is mounted at the front end of the casing; and the optical lenses are focused correspondingly to light paths of the LED light sources. By adopting a display structure of combining the plurality of LED light sources and the plurality of optical lenses, a central line of emergent light from each LED light source is seriously superposed with an optical axis corresponding to each optical lens; the LED light sources are respectively controlled by a control circuit system in a signal lamp body without interference; and when one of the LED light sources in a light emitting board fails, the other LED light sources still normally work, and various optical display parameters outputted by a signal lamp are not changed so as to ensure that the signal lamp normally display.
Description
Technical field
The utility model multiple spot focuses on great power LED signal lamp display unit, is applicable to railway, navigation, and signal lamp Display Techniques such as aviation and traffic belong to signal Display Technique field.
Background technology
At present, with great power LED as the signal lamp display light source in, adopt single 3w or 5wLED as the signal display light source, show safety for guaranteeing signal, by LED commonly used, an identical LED of power is set again as the shared same focus lamp of standby power source.Because of two spot lights can't fully satisfy the optical system design parameter simultaneously, when LED breaks down, cause signal emergent light angle and light intensity etc. to change before and after the standby led light source startup work, produce signal and disturb.
Summary of the invention
The utility model discloses a kind of multiple spot and focuses on great power LED signal lamp display unit, has solved the signal interference problem that conventional great power LED display light source adopts standby LED structure to be easy to generate.
Technical solution of the present utility model is as follows: the aluminium alloy heat sink is located at the focal plane place of a plurality of optical lenses in the housing, be evenly distributed with a plurality of led light sources on the heat sink, the front end of housing is equipped with the lampshade of a plurality of optical lens combinations, and the focusing of optical lens is corresponding with the light path of led light source.
In described display unit, each optical lens is the hemispherical convex lens.
In described display unit, on the lampshade except that the optical lens surface remainder be smooth or the little surface of hair side or convex-concave.
The utility model can provide five kinds of designs according to the great power LED signal lamp display optical system to every profession and trade signal indication technology and unlike signal deixis, and promptly the quantity of a plurality of optical lens combinations on LED quantity and the lampshade is 7～3;
1,7 power of 7 point focusing are 1wLED signal lamp display optical system.
2,6 power of 6 point focusing are 1wLED signal lamp display optical system.
3,5 power of 5 point focusing are 1wLED signal lamp display optical system.
4,4 power of 4 point focusing are 1wLED signal lamp display optical system.
5,3 power of 3 point focusing are 1wLED signal lamp display optical system.
In above-mentioned 5 kinds of schemes, scheme 1,2 and 3 lampshade center all are provided with an optical lens, and other quantity is respectively 6,5 and 4 optical lens and is uniformly set at around the hemispherical of lampshade center.4 optical lenses on the lampshade of scheme 4 are arranged with 2 * 2 matrix forms, and this matrix-geometric center overlaps with the optical lens center.3 optical lenses on scheme 5 lampshades are arranged with equilateral triangle, and the geometric center of this equilateral triangle overlaps with the center of optical lens.
The luminous plaque of above-mentioned 5 kinds of schemes is respectively 7 by power for 1w quantity, and 6,5,4 and 3 s' LED and aluminium alloy heat sink combine, and form 5 groups of signal lamps and show light emitting sources.The number of LED on these 5 groups of luminous plaques is identical with optical lens number on above-mentioned 5 groups of lampshades respectively, the focus point corresponding one by one coincidence respectively of its set-point and optical lens.
Good effect of the present utility model is: adopt multiple spot to focus on great power LED signal lamp display structure, the center line of every led light source emergent light all overlaps with the optical axis of corresponding optical lens is strict, every led light source splits control by the control circuit system in the signal lamp lamp body and does not disturb mutually, when having led light source to break down in the luminous plaque, all the other led light sources are operate as normal still, and each display optical parameter of signal lamp output is not changed, guarantee that signal lamp demonstration work operation is normal.

The specific embodiment
According to shown in Figure 1, the utility model aluminium alloy heat sink 1 is fixed on the focal plane place of a plurality of optical lenses 4 in the housing 5 by bolt 8, be evenly distributed with 3～7 led light sources 2 on the heat sink 1, the front end of housing 5 is equipped with the lampshade 3 that a plurality of optical lenses 4 combine, optical lens quantity is 3～7, and the focus point of optical lens 4 is corresponding with the light path of led light source 2.
In described display unit, each optical lens 4 is the hemispherical convex lens.
In described display unit, be smooth except that the remainders in optical lens 4 surface on the lampshade 3 or hair side or convex-concave little surperficial.
The power of the led light source 2 on the heat sink 1 is 1w, its quantity is corresponding with the quantity of combined optical lens 4 on the lampshade 3 respectively, the location point of each led light source 2 all focus of corresponding with it optical lens 4 overlaps, and the center line of each led light source 2 emergent light is the optical axis coincidence of corresponding with it optical lens 4 all.
Concrete technical parameters of product such as the angle of scattering of the selected LED2 of set basis of design parameters such as the diameter of the hemispherical convex lens 4 in 5 groups of optical lenses 3 of the present utility model and radius of curvature and emergent light light distribution and deciding.
