Background technology
Outside the building views such as profile, square, park, sub-district and various tourist attractions throw light on usually at present.Beautify the environment to reach, in the Landscape Lighting of rendered atmosphere and effect; What generally use is conventional lamp, and like incandescent lamp, fluorescent lamp, high-pressure sodium lamp, metal halide lamp, high-pressure mercury lamp and low-pressure sodium lamp etc., the major defect of this type light fixture is to use the life-span short; Light efficiency is low; Energy consumption is high, and photochromic control is difficult, and volume is big and maintenance cost is high.Also there is a certain distance in this with the requirement that country advocates energy-saving and emission-reduction.
Summary of the invention
The utility model is intended to overcome the above-mentioned deficiency of prior art, and meeting the market requirement provides the collector lens of 12 pearl combined LED Projecting Lamps.Its characteristics: the rounded projection of projection shape of
Figure 812065DEST_PATH_IMAGE001
hot spot, light is concentrated projection;
Figure 591802DEST_PATH_IMAGE002
illumination projection evenly, photochromic can conversion;
Figure 924694DEST_PATH_IMAGE003
light source adopts the LED luminous tube, and energy consumption is low, volume is little, long service life and maintenance cost are low.
For this reason, the collector lens of the utility model 12 pearl combined LED Projecting Lamps adopts following technical scheme:
The collector lens of structure the utility model 12 pearl combined LED Projecting Lamps; Comprise lens body; Said lens body comprises 12 condensing bodies; Said condensing body is circular cone shape, and the big bottom of its condensing body is the exit facet of condensing body, and the exit facet of 12 condensing bodies is positioned at same plane and constitutes the exit facet of the collector lens of 12 pearl combined LED Projecting Lamps; The little bottom of its condensing body is shaped on the pilot hole that light emitting diode is installed, and light emitting diode is installed on said pilot hole, and the hole wall that the exit facet of pilot hole and said condensing body is relative is the plane of incidence of condensing body; 12 said condensing bodies are arranged like this: arrange 9 said condensing bodies in the outer ring and be arranged in circle, 3 said condensing bodies are triangularly arranged in the centre; On the exit facet of the collector lens of 12 pearl combined LED Projecting Lamps, make latticed finish coat, said latticed finish coat is arranged in a combination by numerous regular polygon convexity or the circular protrusions on the exit facet of the collector lens that is produced on 12 pearl combined LED Projecting Lamps.
Technique scheme is further set forth:
Be shaped on the assembling step on the lens body, so that lens body and installation carrier are equipped.
Be shaped on the reference column that strengthens the lens body mechanical strength on the lens body, said reference column is column, and the short transverse of its reference column is consistent with the short transverse of said condensing body, and reference column is positioned at the position, space between the condensing body of inner of lens body.
The concrete shape of the plane of incidence designs according to the crevice projection angle that optical characteristics and this projection source of light emitting diode requires to reach.
Lens body is made with transparent material, like plastic cement PMMA etc.
The beneficial effect of the utility model is: one of which, and the rounded projection of projection shape of hot spot, ray cast is scattered and is angle 30 degree, and light is concentrated projection; Its two, illumination projection evenly photochromicly can realize conversion through the LED wick (being light emitting diode) of more changing different colours; Its three, light source adopts light emitting diode, energy consumption is low, volume is little, long service life and maintenance cost are low.
