Description
Technical field
The utility model relates to the illumination electronic technology, particularly relates to a kind of technology that can effectively control the controlled light-distribution LED illuminating lamp of light distribution.
Background technology
The LED illuminating lamp is compared traditional lighting lamps such as incandescent lamp, high-pressure mercury lamp, Halogen lamp LED, has advantage energy-conservation, efficient, environmental protection.In actual use, than higher, such as road or tunnel illuminating lamp, require its irradiation area is thin-and-long to some environment for use to lighting requirement, and light is bigger along light intensity distribution on the road direction, and the light intensity distribution is less on perpendicular to road direction.
Present road or tunnel LED illuminating lamp is formed each LED lamp of light source and all is located on the same substrate, and adds a big reflection shield on the light-emitting area of led light source light is reflected, to satisfy the requirement of light distribution as much as possible.This illuminating lamp has following defective: the 1) light of big reflection shield reflection, its light distribution can not be adjusted according to actual needs, thereby can not satisfy the requirement of actual use, and the use of big reflection shield also can increase the weight and the expenditure cost of light fixture, and the structure of light fixture is also bigger; 2) big reflection shield edge is far away apart from each LED lamp, and " ghost image " phenomenon of light is very serious, and its illuminating effect is very poor; 3) since each LED lamp all be located on the same substrate, large-area substrate and shell to contact effect relatively poor, be unfavorable for dispelling the heat.
The utility model content
At the defective that exists in the above-mentioned prior art, technical problem to be solved in the utility model provide a kind of in light weight, cost is low, structure is little, good illumination effect, good heat dissipation, and can effectively control the controlled light-distribution LED illuminating lamp of light distribution.
In order to solve the problems of the technologies described above, a kind of controlled light-distribution LED illuminating lamp provided by the utility model, comprise the housing of being with radiator, be installed at least two bar shaped luminescence units and the outer face shield of luminescence unit in the housing, each bar shaped luminescence unit comprises a plurality of LED illuminators that wiring board and linearly shape mounted thereto are arranged, it is characterized in that: described bar shaped luminescence unit and housing fit tightly installation, and the angle angle is less than 180 degree or greater than 180 degree between the light-emitting area of each bar shaped luminescence unit; On the wiring board of described bar shaped luminescence unit reflector is installed, described reflector is formed by at least two strip grooves, and it is corresponding one by one with the LED illuminator and it is stretched out outside the hole that the corresponding row LED illuminator of every groove, groove bottom land are provided with through hole.
Further, the both sides reflection wall of described groove is plane or curved surface.
Further, described reflector is made by aluminium flake.
The controlled light-distribution LED illuminating lamp that the utility model provides has following beneficial effect:
1) owing to the light-emitting area at light source is equipped with reflector, reflector is provided with the groove of corresponding each bar shaped luminescence unit, cell wall by groove reflexes to required direction with light, thereby reasonable distribution light, reach the light distribution requirement of road, therefore big reflection shield compared to existing technology has the advantages that structure is little, in light weight, cost is low;
2) because light source is many bar shaped luminescence units, each bar shaped luminescence unit independently is installed in the housing, because the effect of small size contact is better than the large tracts of land contact, thereby the light source of integral installation compared to existing technology, under the identical situation of total light-emitting area, more help heat radiation;
3) since the light-emitting area of light source be spliced by the light-emitting area of many bar shaped luminescence units, can come by the angle between the light-emitting area of regulating each bar shaped luminescence unit light is carried out luminous intensity distribution, thereby after the cell wall of groove is once regulated and control the light distribution of light source, light is carried out the secondary regulation and control, thereby further reasonable distribution light satisfies the light distribution requirement of road;
4) because the groove cell wall of each LED lamp both sides is reflective surface, its edge and LED lamp spacing are nearer, thereby can effectively reduce " ghost image " phenomenon of light.
