Background technology
As it is known, for example permitted using the conventional lamp of discharge lamp by lamp relative to the different installation sites of reflector Perhaps the characteristics of luminescence is changed.
In LED lamp, this possibility is not allowed to, and manufacturer is forced to manufacture different moulds for every kind of be used alone Type.
It is this to limit the convenience for having had a strong impact on prefabricated elements, therefore have impact on cost.
In order to avoid the defect while ensuring good yield, LED lamp manufacturer has employed a variety of strategies.
The first solution is to prepare plate according to the photometric system intentionally got, and each LED therein has not With tilting pattern (mosaic) is spelled so as to produce best spot.
The solution allows to utilize the potential maximum possible degree of LED, without being subtracted using additional correction optical component Small luminous intensity, however, the solution is very expensive for industrialization angle.
Another solution more less expensive than this kind of scheme before is the multirow LED of preparation onboard, and right Apply different lens and lenticule in each LED, its task is suitably diffused light.
Another solution is onboard to prepare multirow LED, in a manner of similar to conventional lights, around each LED cloth The refractor of special luminosity pattern can be limited by putting.
Known to provide a kind of refractor of two elements, the two elements are usually defined as primary optical system and secondary optical system System.
The light launched with the LED unit for carrying lens is reflected by primary optical system first, then passes through secondary optical system System refraction.
This construction allows the luminosity pattern for changing each LED unit, optical system of the combination with different qualities.
The defects of this system, is each optical solutions and used LED unit tight association, and with The reciprocation tight association of other lighting units in identical light fixture.
In other words, the light fixture manufactured using the system must accurately be installed according to design and can not be otherwise Use.
For productive viewpoint, it is necessary to substantial amounts of optical element is provided, and each is only capable of with being that its is designed Special optical element is applied in combination.
WO2013009197 discloses a kind of light fixture of the above-mentioned type, and it has input lens and output lens group panel, The input lens have fixed or adjustable focal length, and the output lens group panel has fixed or adjustable relative to input lens Position.By using different plug-in packages, output lens can be tilted relative to input lens with different angle.
The content of the invention
It is an object of the present invention to provide a kind of LED light device with Modularized optical system, which overcome above-mentioned existing There is the defects of technology.
In the range of this target, it is an object of the invention to provide a kind of device, and it, which allows to reduce to provide to have, does not share the same light Spend the quantity of the different types of optical element needed for the lighting unit of characteristic.
The free-revving engine of the present invention is to provide a kind of device, and it allows not replace any element, and it is installed therein to change it Light fixture photometric property.
Another object is to provide a kind of lighting device, and it allows in the case where not replacing any element, in its installation place Change the photometric property of light source (luminaire), in addition it is also such to terminal user.
It is a further object of the present invention to provide a kind of device, and it can maximally ensure to use by specific architectural characteristic In reliability and security.
This target hereinafter become more apparent from and these and other objects had into modular optical by one kind The LED light device of system realizes that the lighting device includes at least one LED element, and associated simultaneously with the LED element It is adapted at least one lighting module that the light beam of the LED element transmitting is distributed according to given luminosity pattern；The spy of described device Sign is that the lighting module includes main optical element and secondary optical element, the secondary optical element and the main optical element Cooperate to distribute the light beam；The secondary optical element of advocating peace is interchangeable to change the luminosity pattern；Identical pair light Identical main optical element can be applied to change the luminosity pattern in different opening positions by learning element.

Embodiment
It is overall by accompanying drawing mark according to the LED light device with Modularized optical system of the present invention with reference to the accompanying drawing Note 1 represents that it includes the supporting plate 2 being connected with radiator 3, and the radiator is made up of the main body provided with fin --- preferably by gold Category, such as aluminium are made.
Supporting plate 2 has multiple seats 4, and each seat is adapted to accommodate corresponding lighting module 5.
Each lighting module 5 is arranged at the LED element 6 being made up of accordingly one or more LED, the LED element cloth It is placed on substrate 7, substrate 7 is connected to radiator 3.
According to the present invention, each lighting module 5 has main optical element 8 and secondary optical element 9, and the secondary optical element is can Become.
Main optical element 8 can be made up of reflector and/or lens or light guide therefor.
Secondary optical element 9 is advantageously made up of interchangeable disk, and the disk can be configured with different light diffusion and transmission Characteristic.
According to preferred embodiment, disk 9 is optional and optionally has a series of special-shaped region 10 in both sides.
Special-shaped region 10 can be made up of prism-like recess or other appropriate shapes, and the shape is adapted to according to pre-selection luminosity Pattern carrys out deflecting light beams.
According to the present invention, secondary optical element 9 is connected with main optical element 8 by bayonet coupling or other connection systems, The connection system allows secondary optical element 9 to have the variable anglec of rotation relative to main optical element.
As an example, Figure 4 and 5 show the secondary optical element 9 in main optical element, it is between the two positions It has rotated 90 °.
Bayonet connection system or other pre-selection connection systems can be structured as allowing secondary optical element 9 with different (discrete Or it is continuous) angle assembling, so as to allow change light beam direction and distribution, and therefore change device luminosity pattern.
In order to ensure watertightness and moisture-proof, secondary optical element 9 is arranged in main optical element 8 and is disposed between the two Packing ring 13.
Lighting device 1 can be used for having in the light fixture of a variety of shapes and sizes.
Fig. 7-9 shows the example that lighting device 1 is applied in light fixture 100, and the light fixture of thermoplastic material by being for example made up Shell 101 form.
The storing apparatus 1 in the holding part adjacent with compartment 102 of shell 101, the compartment are accommodated and are not shown in the drawings Power supply and control system.
