Abstract
The utility model discloses a vacuum film-coated directional-lighting low-temperature sodium lamp, comprising an amalgam, a vacuum film coating layer, an outside-tube glass housing, a light transmitting layer, a spiral light emitting tube, and a lamp holder spiral tip. According to the utility model, an upper part of the outside-tube glass housing of the low-temperature sodium lamp is subjected to vacuum film coating, such that light can only irradiate downwardly from the glass housing outside the low-temperature sodium lamp, thereby achieving the purpose of directional light-reflecting for illumination; and as the upper part of the outside-tube glass housing of the low-temperature sodium lamp is subjected to vacuum film coating, the light source can be completely reflected, and the lamp cannot be covered by dust, improving the lighting brightness, reducing the repair cost and saving the maintenance cost of the street lamp.
Description
Technical field
The present invention relates to the technical field of illuminating lamp, especially refer to a kind of vacuum coating directional lighting low temperature sodium vapor lamp.
Background technology
Low-pressure sodium lamp is the electric light source that utilizes the low pressure sodium vapor discharge luminous, is coated with infrared reflection film in its glass shell, is the less and the highest electric light source of luminous efficiency of light decay.What low-pressure sodium lamp sent is monochromatic gold-tinted, be used for the photochromic place that does not require, but its " mist transmitting " shows very remarkably, is particularly suitable for highway, traffic route, town road, public circle, garden illumination, can make the people clearly see the object that aberration is smaller.Low-pressure sodium lamp is also a kind of efficient lamp kind that substitutes the high-pressure mercury lamp electrical energy saving, and application places is also in continuous expansion.Traditional street lamp adopts low-pressure sodium lamp as light emitting source, need to reflector be installed on fluorescent tube top, and after using a period of time, reflector is easily covered by dust, causes the not enough defective of light source reflection, affects the street lamp illumination effect.
Summary of the invention
A kind of vacuum coating directional lighting of the present invention low temperature sodium vapor lamp, employing glass shell the first half outside the fluorescent tube of low temperature sodium vapor lamp is carried out vacuum coating, and light can only be shone downwards by glass shell outside the low temperature sodium vapor lamp, realizes the purpose of orienting reflex luminous lighting.
To achieve these goals, technical solution of the present invention is: a kind of vacuum coating directional lighting low temperature sodium vapor lamp comprises by amalgam, vacuum coating, the outer glass shell of fluorescent tube, photic zone, spiral luminous pipe, lamp holder helical-tip and forming; The inside of spiral luminous pipe arranges electrode and pressurising and receives gas, front portion at the spiral luminous pipe arranges amalgam, spiral luminous pipe afterbody arranges lamp holder helical-tip, the outer glass shell of spiral luminous pipe outer setting fluorescent tube, the first half of the outer glass shell of fluorescent tube is carried out vacuum diaphragm and is formed vacuum coating, the bottom is photic zone, is vacuum coating directional lighting low temperature sodium vapor lamp.
Beneficial effect of the present invention: the outer glass shell the first half of the fluorescent tube of low temperature sodium vapor lamp is carried out not only abundant reflection source of vacuum coating, and can not covered by dust, has namely increased illumination brightness, has reduced again maintenance cost, has saved the maintenance cost of street lamp.
Description of drawings
Below in conjunction with the drawings and specific embodiments, invention is further described.
Accompanying drawing is a kind of vacuum coating directional lighting low temperature sodium vapor lamp schematic diagram.
In figure: 1, amalgam, 2, vacuum coating, 3, the outer glass shell of fluorescent tube, 4, photic zone, 5, the spiral luminous pipe, 6, lamp holder is most advanced and sophisticated.
Embodiment
Shown in accompanying drawing, the directed low temperature sodium vapor lamp of a kind of vacuum coating comprises by being comprised of amalgam 1, vacuum coating 2, the outer glass shell 3 of fluorescent tube, photic zone 4, spiral luminous pipe 5, lamp holder helical-tip 6; The inside of spiral luminous pipe 5 arranges electrode and pressurising and receives gas, in the front portion of spiral luminous pipe 5, amalgam 1 is set, spiral luminous pipe 5 afterbodys arrange lamp holder helical-tip 6, the outer glass shell 3 of spiral luminous pipe 5 outer setting fluorescent tubes, the first half of the outer glass shell 3 of fluorescent tube is carried out vacuum diaphragm and is formed vacuum coating 2, the bottom is photic zone 4, is vacuum coating directional lighting low temperature sodium vapor lamp.
The above; execution mode is only that the preferred embodiment of the present invention is described; be not that scope of the present invention is limited; under the prerequisite of the spirit that does not break away from the technology of the present invention; various distortion and improvement that this area engineers and technicians make technical scheme of the present invention all should fall in the definite protection range of claims of the present invention.
