Description
Technical field
The present invention relates to lamp lighting technical field, specifically a kind of Chinese lamp and its light distributing method.
Background technology
Chinese lamp, by its distinctive national characters, cultural spirit, is widely used as a kind of street lamp of great characteristic
The places such as central plaza, major trunk roads in each city.
The most significant feature of Chinese lamp is the structure of its fire of eight fork nine.The Chinese lamp of early stage, eight nine fiery structures of fork
Only be decoration function, have no substantial photocurrent versus light intensity, and the lamp box structure of centre, though there is illuminating effect, light is main
Launch to surrounding, lack the light being aimed downwardly, light can not effectively be irradiated to ground, therefore the Chinese lamp of this structure
It is attractive in appearance have a surplus it is but and impracticable, mainly as Landscape Lighting.The Chinese lamp in later stage, in order to improve road surface brightness, in original knot
On structure, downward Projecting Lamp is mounted with.Though this structure improves road lighting environment, it is original attractive in appearance to have impact on Chinese lamp
Characteristic, and extra configuration Projecting Lamp is needed, increase cost.
Patent No. CN203963704U utility model patent discloses a kind of " head of Chinese style lamp ", and it is horizontally disposed
Lamp holder base on more than one LED lamp bead is installed, by being correspondingly arranged a collector lens in each LED lamp bead, will
The light that all LED lamp beads are sent sets one in round table-like by collector lens focus in a focal point, and in focal point
And the mirror lens of cone tank is provided with the middle part of top surface so that most light can be reflexed under lampshade by mirror lens
Side, the illumination of light road pavement is improved with this.Although this lamp holder improves road surface brightness, but product structure is more complicated,
Multiple collector lenses and mirror lens are needed to be used cooperatively, production cost is high, and assembly difficulty is big, and main weak point exists
In downward light distribution device is integrated on eight lamp holders, though solving road surface light missing problem, road illumination is still suffered from
Problem of non-uniform.
The content of the invention
The defects of in order to overcome above-mentioned prior art, the technical problems to be solved by the invention are to provide a kind of structure letter
Chinese lamp and its light distributing method single, the efficiency of light energy utilization is high.
In order to solve the above-mentioned technical problem, the technical solution adopted by the present invention one is：
A kind of Chinese lamp, including lamp box, the lamp box is interior to be provided with more than one LED light source module, the side of the lamp box
Inward-facing to be tiltedly installed with optical transmission window, the optical transmission window is provided with diffuser, and the LED light source module is towards diffuser one
Side is inclined on the upper wall of lamp box, and the polarisation that the LED light source module includes LED lamp bead and is located in LED lamp bead is saturating
Mirror, the light that the LED lamp bead is sent by full illumination after spreadlight lens polarisation to diffuser in the range of.
In order to solve the above-mentioned technical problem, the technical solution adopted by the present invention two is：
A kind of light distributing method of Chinese lamp, the optical transmission window of lamp box side is sloped inwardly and set, set on optical transmission window
Diffuser, LED light source module is inclined on the upper wall of lamp box towards diffuser side, the LED light source module includes
LED lamp bead and the spreadlight lens being located in LED lamp bead, are arrived the light whole polarisation that LED lamp bead is sent using spreadlight lens
In the range of diffuser.
The beneficial effects of the present invention are：It is different from prior art, the present invention is by LED light source module towards diffuser side
It is inclined on the upper wall of lamp box, and using spreadlight lens by the light whole polarisation that LED lamp bead is sent to diffuser scope
It is interior, the light that LED lamp bead is sent all is projected by diffuser below lamp box, satisfied the need so as to substantially increase light
The illumination in face, reduce light source and waste, light utilization is high；Luminous intensity distribution is carried out by spreadlight lens, road illumination can be made uniform, and
Meet road illumination standards, realize Chinese lamp-based street lamp；And the light that LED lamp bead is sent passes through spreadlight lens and diffuser
It is that projection is gone out afterwards, avoids optical energy loss caused by light is repeatedly reflected and reflected, therefore the efficiency of light energy utilization is high, structure letter
It is single, it is readily produced and assembles.
