Abstract
The invention belongs to the field of lighting devices and specifically discloses a lamp capable of increasing an irradiation distance. The lamp comprises a housing, an LED lamp bulb located within the housing, and a reflecting cup arranged to cover the LED lamp bulb and connected with the housing; the lamp further comprises a plurality of lenses connected with the reflecting cup in a circumferential direction; each lens is circular-ring-shaped, and a face, close to the LED lamp bulb, of the lens is toothed, while the other face of the lens is a plane. The lamp is capable of increasing the irradiation distance.
Description
Technical field
The present invention relates to field of illuminating device, be specifically related to a kind of light fixture extending irradiation distance.
Background technology
LED lamp is as new and effective solid light source, the remarkable advantages such as it has that luminous efficiency is high, long service life, energy-conserving and environment-protective, rich color, flexibly controlled, response are quick, microminiaturized, easy of integration, safe and reliable are 21 century green illumination light sources most with prospects.LED illumination light source has been widely used in the fields such as Landscape Lighting, street lighting, large screen display, backlight.
At present, high-power LED light fixture is wide cut mostly, carries out luminous intensity distribution with the form of single reflector, and LED bulb is arranged on the bottom of reflector.The light that LED bulb sends, a part is directly shone out by the opening of reflector, and the opening of another part again by reflector after being reflected by reflector is shone out.The angle of emergence of existing LED lamp is comparatively large, causes the irradiation distance of LED lamp shorter, some is needed at a distance to the situation of cover, can not meet the demands.
Summary of the invention
The object of the present invention is to provide a kind of light fixture extending irradiation distance, this light fixture can extend the irradiation distance of LED.
For achieving the above object, base case of the present invention is as follows: a kind of light fixture extending irradiation distance, comprises housing, is positioned at the LED bulb of described housing and is located at described LED bulb periphery and the reflector be connected with described housing; Also comprise multiple lens coupled along the circumference of reflector, described lens are circular and described lens is zigzag near LED bulb face, and described lens another side is plane.
Operation principle of the present invention and beneficial effect are: LED bulb luminescence is penetrated in certain scope by the reflection of reflector.Housing is provided with multiple lens, and one side is zigzag, one side is plane.Reflect after the light that then LED bulb sends arrives lens, major part light ray parallel shines out in the center line of reflector, namely major part is to penetrate with the straight line of casing center line parallel, compared with prior art, decrease the light collecting in focus, thus decrease divergent rays, and then further reduce the angle of emergence of the light that LED bulb sends, namely further reduce the angle of emergence of LED lamp, make the light of LED lamp more concentrated, thus further increase the irradiation distance of LED lamp.And in this programme, lens are annular, so the light along reflector centerline parallel sent from LED bulb not scioptics, can not reflect, avoid light scioptics and weaken.
Preferred version one: based on the preferred version of scheme, described lens internal diameter diameter is identical, can make to occur in LED bulb to avoid it to weaken along the light of reflector centerline parallel as far as possible, makes irradiation distance longer.
Preferred version two: the preferably preferred version of, described housing exterior walls is provided with radiating fin, can the heat produced during LED bulb luminescence be distributed as soon as possible.
Preferred version three: the preferably preferred version of two, the quantity of described lens is 3-6, experimentally known, and 3-6 lens can ensure that light that LED bulb sends makes light weaken by avoiding light through repeatedly reflecting along reflector centerline parallel.
Preferred version four: based on scheme or the preferred version described in any one of preferred version one-three, described housing is covered with dust cover, can prevents dust from falling on lens, affect the refraction of lens.
Accompanying drawing explanation
Fig. 1 is the structural representation that the present invention extends the light fixture embodiment of irradiation distance.
Detailed description of the invention
Below by detailed description of the invention, the present invention is further detailed explanation:
Reference numeral in Figure of description comprises: housing 10, reflector 20, LED bulb 30, lens 40, dust cover 50.
Embodiment is substantially as shown in Figure 1: a kind of light fixture extending irradiation distance, comprises housing 10, is positioned at the LED bulb 30 of housing 10 and is located at the peripheral and reflector 20 be connected with housing 10 of LED bulb 30; This light fixture also comprises multiple lens 40 coupled along the circumference of reflector 20, and lens 40 are circular and lens 40 are zigzag near LED bulb 30, and lens 40 another side is plane.Lens 40 internal diameter diameter is identical, can make to occur in LED bulb 30 to avoid it to weaken along the light of reflector 20 centerline parallel as far as possible, makes irradiation distance longer.Housing 10 outer wall is provided with radiating fin, can the heat produced during LED bulb 30 luminescence be distributed as soon as possible.The quantity of lens 40 is 3-6, experimentally known, 3-6 lens 40 can ensure LED bulb 30 send light and through repeatedly reflecting, light weakened by avoiding light along reflector 20 centerline parallel.Housing 10 is covered with dust cover 50, can prevents dust from falling on lens 40, affect the refraction of lens 40.
LED bulb 30 luminescence is penetrated in certain scope by the reflection of reflector 20.Be provided with multiple lens 40 on the housing 10, and one side is zigzag, one side is plane.Reflect after the light that then LED bulb 30 sends arrives lens 40, major part light ray parallel shines out in the center line of reflector 20, namely major part penetrates with collimated ray, compared with prior art, decrease the light collecting in focus, thus decrease divergent rays, and then further reduce the angle of emergence of the light that LED bulb 30 sends, namely further reduce the angle of emergence of LED lamp, make the light of LED lamp more concentrated, thus further increase the irradiation distance of LED lamp.And in this programme, lens 40 are annular, so the light along reflector 20 centerline parallel sent from LED bulb 30 not scioptics 40, can not reflect, avoid light scioptics 40 and weaken.
Above-described is only embodiments of the invention, and in scheme, the general knowledge such as known concrete structure and characteristic does not do too much description at this.Should be understood that; for a person skilled in the art, under the prerequisite not departing from structure of the present invention, some distortion and improvement can also be made; these also should be considered as protection scope of the present invention, and these all can not affect effect of the invention process and practical applicability.The protection domain that this application claims should be as the criterion with the content of its claim, and the detailed description of the invention in description etc. record the content that may be used for explaining claim.
