LED polarisation underground lamp
The present invention relates to a kind of LED polarisation underground lamp, be mainly used in outdoor scene illumination, projection plant or buildings.
At present, for outdoor underground lamp illumination, mainly contain following several lighting system:
1, common ground formula gold halogen light source Projecting Lamp: install and use on ground, and have certain adjusting angle, can regulate according to demand lighting angle.The mode of this kind of illumination is interior as leading for a long time, but also has the condition restriction of self, and luminosity is poor, power consumption is large, service life is short, and is easy to stolen.
2, LED underground lamp, on the ground, and light-emitting area and ground are substantially in same level for potting; Although this kind of LED underground lamp is from electrically considering to have solved most of energy-conservation problem, avoided as much as possible the stolen possibility of lamp simultaneously, but the radiation direction of getting is luminous directly over being, the lighting angle branch that is centrosymmetric, cause most of light can not partially be mapped on irradiated object on one side, wasted most of light source.
Summary of the invention
For the above-mentioned technical deficiency existing in technical solution background, the invention provides a kind of LED spreadlight lens, use spreadlight lens to carry out secondary optics processing, to reach most of light that LED sends, all project on illuminated object.
The present invention, is characterized in that: comprise the spreadlight lens of a waterproof base, a power panel, a light source board with radiator, a supporting light source board, a glass cover-plate and an associated waterproof grommet, a stainless steel cover plate and one group of screw; Spreadlight lens mainly carries out optically focused and refraction by light.
Bulb lamp according to claim 1, is characterized in that: use spreadlight lens module, carry out secondary optics, most of light can be projected on target object.
Technique scheme, has following beneficial effect at least:
The present invention is as a kind of underground lamp, owing to having used spreadlight lens, make most of light full illumination to illuminated object, light is fully utilized, not only reach more energy-conservation effect, and the pollution of the light of the environment reducing evil, the stolen chance of light fixture reduced, and production technology is easy to realize, and is easy to user and applies.
Accompanying drawing explanation
Below in conjunction with accompanying drawing and specific embodiment, the present invention is described in further detail.
Fig. 1 is three-dimensional structure diagram of the present invention;
Fig. 2 is exploded view of the present invention and spreadlight lens three-dimensional structure diagram;
In figure, 1, CARBURIZING FURNACE FOR STAINLESS FASTENER; 2, the fixing housing of stainless steel; 3, waterproof apron; 4, glass; 5, with the LED light source plate of radiator; 6, spreadlight lens; 7, power supply module; 8, waterproof drain pan; 9, the enlarged drawing of spreadlight lens;
The specific embodiment
Referring to Fig. 1 and Fig. 2, the embodiment of the present invention provides a kind of LED polarisation underground lamp, and it mainly comprises: CARBURIZING FURNACE FOR STAINLESS FASTENER 1, stainless steel be housing 2, waterproof apron 3, glass 4, the LED light source plate 5 with radiator, spreadlight lens 6, power supply module 7, waterproof drain pan 8 fixedly.Owing to having designed a kind of spreadlight lens in this case embodiment, LED light beam is assembled and refraction through spreadlight lens, and the light of finally getting can be partial to a side of light fixture central shaft.Thereby reaching light can be irradiated on the object of light fixture one side substantially completely.The reasonable in design of this bulb lamp, the overall tightness of product is very good, and insulating properties are high, and product is easy to safeguard and apply.
The above is the specific embodiment of the present invention; it should be pointed out that the those of ordinary skill of implementing for the art, do not departing under the prerequisite of using the principle of the invention; can also make some improvements and modifications, these improvements and modifications are also considered as protection scope of the present invention.
