The LED lamp with long irradiation distance comprises an LED lamp tube and a shell, wherein the shell is provided with an installation hole; the LED lamp tube is positioned in the shell and is connected with one end of the shell. The LED lamp with long irradiation distance is characterized in that the inner wall of the shell is provided with a semi-spherical light reflection cup; the inner wall, far away from one end of the LED lamp tube, of the shell is provided with a circular light reflection sheet. The applied lamp has long irradiation distance.
Description
Technical field
The present invention relates to field of illuminating device, be specifically related to the LED lamp that a kind of irradiation distance is long.
Background technology
Light emitting diode is called for short LED, electric energy conversion can be become luminous energy.LED is called as forth generation light source, and LED illumination technology obtains significant progress, and the raising of epitaxy technology makes the cost of LED chip greatly reduce, and LED has inherent superior quality, and such as luminous efficiency is high, bright.LED lamp, as new and effective solid light source, is 21 century green illumination light source 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.It is comparatively large that existing LED lamp has the angle of emergence, causes the irradiation distance of LED lamp shorter, some are 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 the LED lamp that a kind of irradiation distance is long.
For achieving the above object, base case of the present invention is as follows: the LED lamp that a kind of irradiation distance is long, comprise LED lamp tube and housing, described housing is provided with installing hole, described LED lamp tube is positioned at housing and is connected with shell one end, and described inner walls is provided with reflector, and described reflector is hemispherical, described housing is provided with reflecting piece away from LED lamp tube one end inwall, and described reflecting piece is annular.
Operation principle of the present invention and beneficial effect are: first installed by light fixture by the installing hole on housing, make it fix.On housing, one end is connected with LED lamp tube, and LED lamp tube is light source, can be luminous.The centerline parallel of the light that LED lamp tube sends some and housing, can directly penetrate from housing.Other light comparatively disperseed are irradiated on reflector after then launching, because reflector is spherical in shape, then can makes light and casing center line parallel through the reflection of reflective cup after illumination is mapped to reflector and penetrate.Be provided with reflecting piece at shell one end, reflecting piece is annular, then do not affect and penetrate from reflecting piece with the light of casing center line parallel.If light is when penetrating from housing, if not with casing center line parallel, then light can shine directly in reflecting piece, and reflecting piece can stop light to penetrate from housing.Then light is irradiated to again on reflector through the reflection of reflecting piece, then then penetrates through reflecting the light becoming its path and casing center line parallel, and the light penetrated from housing is like this all just the light with casing center line parallel, can increase the irradiation distance of light.
Preferred version one: based on the preferred version of scheme, described housing exterior walls is provided with radiating fin, and radiating fin can play thermolysis.
Preferred version two: the preferably preferred version of, the diameter of bore of described reflecting piece equals the diameter of housing mounted LED lamp pipe end, can guarantee to be optimum with the beam size of casing center line parallel like this, make irradiation distance long.
Preferred version three: the preferably preferred version of two, described housing is covered with dust cover, and dust cover can play dustproof effect, avoid reflecting piece to be stained with reflection that dust affects light.
Accompanying drawing explanation
Fig. 1 is the structural representation of the LED lamp embodiment of irradiation distance of the present invention length;
Fig. 2 is the structural representation of the LED lamp embodiment of irradiation distance of the present invention length.
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, radiating fin 11, LED lamp tube 20, reflector 30, reflecting piece 40, dust cover 50.
Embodiment is substantially as depicted in figs. 1 and 2: the LED lamp that a kind of irradiation distance is long, comprise LED lamp tube 20 and housing 10, housing 10 is provided with installing hole, LED lamp tube 20 is positioned at housing 10 and is connected with housing 10 one end, housing 10 inwall is provided with reflector 30, reflector 30 is in hemispherical, and housing 10 is provided with reflecting piece 40 away from LED lamp tube 20 one end inwall, and reflecting piece 40 is in annular.Housing 10 outer wall is provided with radiating fin 11, and radiating fin 11 can play thermolysis.The diameter of bore of reflecting piece 40 equals the diameter of housing 10 mounted LED lamp pipe 20 end, can guarantee to be optimum with the beam size of housing 10 centerline parallel like this, make irradiation distance long.Housing 10 is covered with dust cover 50, dust cover 50 can play dustproof effect, avoid reflecting piece 40 to be stained with reflection that dust affects light.
First by the installing hole on housing 10, light fixture is installed, make it fix.One end is connected with LED lamp tube 20 on the housing 10, and LED lamp tube 20 is light source, can be luminous.The centerline parallel of the light that LED lamp tube 20 sends some and housing 10, can directly penetrate from housing 10.Other light comparatively disperseed are irradiated on reflector 30 after then launching, because reflector 30 is spherical in shape, then can makes light and housing 10 centerline parallel through the reflection of reflective cup after illumination is mapped to reflector 30 and penetrate.Be provided with reflecting piece 40 in housing 10 one end, reflecting piece 40 in annular, does not then affect and penetrates from reflecting piece 40 with the light of housing 10 centerline parallel.If light is when penetrating from housing 10, if not with housing 10 centerline parallel, then light can shine directly in reflecting piece 40, and reflecting piece 40 can stop light to penetrate from housing 10.Then light is irradiated to again on reflector 30 through the reflection of reflecting piece 40, then then penetrate through reflecting the light becoming its path and housing 10 centerline parallel, the light penetrated from housing 10 is like this all just the light with housing 10 centerline parallel, can the irradiation distance of positive growth light.
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.
