State the present invention and simplify description, rather than indicate or imply that the device or element of meaning there must be specific orientation, with specific
Azimuth configuration and operation, therefore be not considered as limiting the invention.In the description of the invention, unless otherwise indicated,
" multiple " are meant that two or more.
Need further to state is：Before being close to the direction of blackboard when blackboard lights is installed in the present invention, away from blackboard
After direction is.
In the description of the invention, it is necessary to which explanation, unless otherwise clearly defined and limited, term " installation ", " sets
Put ", " connection " should be interpreted broadly, for example, it may be being fixedly connected or being detachably connected, or be integrally connected；Can
To be to be joined directly together, it can also be indirectly connected to by intermediary.For the ordinary skill in the art, can basis
Concrete condition understands the concrete meaning of above-mentioned term in the present invention.
Disclosed by the invention is a kind of integrated blackboard lights for being capable of high efficiency and heat radiation, and integral LED as shown in Figure 2 is black
Plate lamp includes：Integrated section bar 4, aluminium base 5, LED array 6, diffuser 7, lamp holder (not shown) and LED drive power 13.Knot
Fig. 2 and Fig. 3 is closed, integrated section bar 4 is tubulose aluminium section bar, is the main enclosure portion of blackboard lights, while also realizing the integration
The radiating of LED blackboard lightses and diffusing reflection function, aluminium base 5 and diffuser 7 are embedded to be arranged on inside integrated section bar 4, one
Changing the front upper part of section bar 4 has the aluminium base mounting groove 41 and diffuser mounting groove for being respectively intended to install aluminium base 5 and diffuser 7
42.Integrated section bar 4 is close at the back side of aluminium base 5, and front is covered with copper, and LED array 6 is being welded on aluminium base 5 just by SMD
LED array 6 is sealed in integrated section bar 4 by face, diffuser 7 from outside, and diffuser 7 is sealing and protects the light source of LED array 6
Transparent PC multimaterial components.Aluminium base 5 is the carrier of LED array 6, and provides specific series-parallel circuit for it.LED array 6
It is the light source of integral LED blackboard lights for regularly arranged light emitting diode.
From front upper place, lower section is extended with the reflector 3 of curved curved surface to integrated section bar 4 backward, and reflector 3 is through sandblasting oxygen
Change is processed into diffusing reflection face, the present embodiment, and the cross section of reflector 3 is parabola, parabolical symmetry axis 12 with it is integrated
The angle α of the vertical central axis 14 of section bar, 20 °≤α≤30 °, in the present embodiment, α=20 °, parabolic equation is y=x2/ 64,
LED array 6 is arranged in parabolical focus, and the incident ray 10 that LED array paroxysm goes out is mapped to after diffuser 7 on reflector 3
Formation and the emergent ray that the angle of the vertical central axis of integrated section bar 14 is 20 ° after reflection.
Integral LED blackboard lights also includes being fixed on the LED drive power 13 inside integrated section bar 4, LED drive power
Civil power 220V is exchanged input by 13, which to be transformed into, can meet the constant pressure that LED array battle array is used.
Sealed at the both ends open of integrated section bar 4 by lamp holder (not shown), lamp holder is by aluminium base 5, diffuser 7, LED
Array 6 and LED drive power 13 are sealed in inside integrated section bar 4.
The top of integrated section bar 4 is fixedly connected on mounting bracket 8, and mounting bracket 8 is cut with scissors with being used for lifting the suspension bracket 9 of blackboard lights
Connect, integral LED blackboard lights can rotate 180 ° relative to suspension bracket 9, the angle between blackboard lights and blackboard is conveniently adjusted, so that light
It is capable of being irradiated on blackboard of maximum area.
Specifically, because LED array 6 is arranged in parabolical focus, the incident ray 10 that LED array 6 is sent is passed through
Vertical irradiation is on reflector 3 after diffuser 7, and the emergent ray after emitted cover reflection is penetrated parallel to parabolical symmetry axis 12
Go out, because symmetry axis 12 with the angle of the vertical central axis of integrated section bar 14 is 20 °, so emergent ray and integrated section bar
The angle of vertical central axis 14 is also 20 °.It is mapped to because the light of the injection of LED array 6 can be passed through after diffuser 7 instead
Penetrate on cover 3, then reflect, no direct light irradiates blackboard lights, the direct light that blackboard lights is projected can be avoided to teacher
Caused dazzle harm.
Because aluminium section bar has good heat dispersion relative to air, the heat that LED is produced by aluminium base 5 and with
The integrated section bar 4 that aluminium base 5 is contacted is distributed rapidly, is radiated using whole integrated section bar 4, is effectively increased radiating surface
Product, it is ensured that LED service life.
, can be high by the integral LED blackboard lights in the present embodiment in order to adapt to the installation site of multi-media classroom projecting apparatus
Installed in projecting apparatus, only need to adjust the angle of reflector 3, light source can be farthest irradiated on blackboard, can
Adapt to the various classroom demands for thering is space to limit.
The above-mentioned desirable embodiment according to the present invention is enlightenment, and by above-mentioned description, relevant staff is complete
Various changes and amendments can be carried out without departing from the scope of the technological thought of the present invention'.This invention it is technical
