Description
Technical field
The utility model relates to a kind of Projecting Lamp, specifically a kind of LED Projecting Lamp.
Background technology
The LED lamp obtains using more and more widely owing to having energy saving, environmental protection, non-damageable characteristics.Traditional LED Projecting Lamp for the more extensive utilization rate that improves light that reaches that can shine, can be taked reflection shield, realizes asymmetric light distribution with this.The light intensity drop of the asymmetric light distribution of the reflective bell-type of this class is less, and general beam intensity ratio can't well be utilized light less than 3: 1.And on the LED assembly mounted lens, be all again generally symmetrical luminous intensity distribution, also can't take full advantage of the rate line.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of effective raising light utilization efficiency, and can realize the LED Projecting Lamp of the asymmetric light distribution that the light intensity drop is larger.
In order to solve the problems of the technologies described above, the utility model is taked following technical scheme:
A kind of LED Projecting Lamp, comprise radiator, be contained in the radiator two ends end cap, be contained in LED assembly, the control light cover in radiator and be contained in cover plate on radiator, this LED assembly comprises aluminium base and the LED lamp of phase attaching, at least two above direction LED assemblies are installed in described radiator, all directions LED component count is different, and all directions LED assembly cover that is contained on the same plane in radiator is loaded onto spreadlight lens; Perhaps all directions LED assembly is contained in the lens of the different not polarisation of beam angle on suit on Different Plane in radiator, the all directions angle is less than the difference of the beam angle that is installed on the lens that the party makes progress, the anterior control light cover of installing of lens, all directions LED assembly uses parallel connection and serial connection to mix and obtains different electric currents, or directly input different electric currents by drive circuit, make all directions have different light intensity.
Described radiator two-port place also is equipped with shading arc sheet.
Also be provided with reflector on described shading arc sheet.
The utility model is by the lens that conplane LED lamp is loaded onto polarisation that are positioned in radiator, perhaps the LED lamp of Different Plane is loaded onto the not lens of polarisation, make the light emission direction of each LED lamp formation more than at least two, and the supply current of the LED lamp on different directions control effectively, realize the larger difference of light intensity drop, thereby consist of the larger asymmetric light distribution of light intensity drop.Also improve the utilization rate of light and the efficient of light fixture, strengthened shielding angle, prevented direct glare.
Description of drawings
Accompanying drawing 1 is the utility model decomposing state structural representation.
The specific embodiment
For the ease of those skilled in the art's understanding, the utility model will be further described below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of LED Projecting Lamp, comprise radiator 1, be contained in radiator 1 two ends end cap 4, be contained in the LED assembly 6 in radiator 1 and be contained in cover plate 5 on radiator 1, this LED assembly 6 comprises aluminium base and the LED lamp of phase attaching, at least two above direction LED assemblies 6 are installed in described radiator 1, all directions LED component count is different, and the cover that all directions LED assembly is contained on same plane in radiator is loaded onto spreadlight lens; Perhaps all directions LED assembly is contained in the lens of the different not polarisation of beam angle on suit on Different Plane in radiator, the all directions angle is less than the difference of the beam angle that is installed on the lens that the party makes progress, the anterior control light cover 8 of installing of lens, all directions LED assembly uses parallel connection and serial connection to mix and obtains different electric currents, or directly input different electric currents by drive circuit, make all directions have different light intensity.In addition, connect for parallel connection and serial connection mixes between each LED assembly, namely exist simultaneously between the LED assembly be connected in series and be connected in parallel.Due to the parallel connection shunting, therefore, when actual design is installed, reducing at needs the LED assembly that the direction of light intensity makes progress the party is connected in parallel, like this with other directions on the light that sends of LED assembly will form larger light intensity drop, the anterior installation control of lens light cover 8 blocks or is reflected back in the setting beam angle overflowing the outer light of setting beam angle, avoids affecting all directions beam intensity ratio and eliminates direct glare.
In addition, 1 two-port place also is equipped with shading arc sheet 2 at radiator, can be used for strengthening shielding angle, prevent direct glare.Also be provided with reflector 3 on shading arc sheet 2, the light that overflows the workspace can be recycled, greatly improve the utilization rate of light and the efficient of whole light fixture.This reflector 3 can be integrated formed structure with shading arc sheet 2, and whole shading arc sheet 2 and reflector 3 also can with radiator 1 structure that is formed in one.
In addition, the LED assembly of installing in radiator is too much, and when causing each other distance can't satisfy the uniformity to require, can use the striped lens with two kinds of beam angles this moment, and namely each LED lamp is set with the striped lens.
In technical solutions of the utility model, each LED lamp is contained on same plane in radiator, adopt the lens of the different polarisation of beam angle as the lampshade of LED lamp, the light that the LED lamp is sent has multiple directions, and make the angle of any two light emission directions less than the difference of the beam angle that is positioned at the lens on this two direction, so just can so that the utilizing emitted light of all directions becomes stack by distributing side by side to distribute, form the larger asymmetric light of light intensity drop.In addition, each LED assembly also carries out series-parallel connection and connects, and namely has simultaneously the circuit that is connected in series and is connected in parallel, like this, on the circuit that is connected in parallel, due to the parallel connection shunting, make this a part of electric current less, the LED lamp luminosity of this part is lower, forms stronger light intensity drop.And the LED assembly of varying number is installed on each direction, the light intensity that will form like this different directions is inconsistent, forms the light intensity drop.
