The invention has the beneficial effects as follows: the present invention adopts semi-enclosed heat-radiating rod that light emitting diode is installed, by through hole the circuit of light emitting diode is drawn with external circuit and to be connected, the place ahead then by the radiation panel that is connected with reflector, lens, elements such as sealing ring are fixed together, realized that illuminating module is in the positive structure that all seals with the back side, had better radiating effect simultaneously concurrently, be provided with in each sets of elements of the present invention, in the time of in being installed in the street lamp housing, the circuit that only needs to draw by through hole is connected with external circuitry, other directions then seal relatively not to be needed to adjust, it is easy for installation, is a kind of illumination module with good waterproof and radiating effect.
Description of drawings
The invention will be further described below in conjunction with the drawings and specific embodiments:
Fig. 1 is a fractionation structural representation of the present invention;
Fig. 2 is a cross sectional representation of the present invention;
Fig. 3 is a longitudinal section of the present invention schematic diagram.
The specific embodiment
With reference to Fig. 1~Fig. 2, the waterproof construction of a kind of LED illumination module provided by the present invention, comprise light emitting diode 1 and the inner heat-radiating rod 2 that is provided with through hole 21, heat-radiating rod 2 fronts are provided with the installing hole 22 that is communicated with through hole 21, described light emitting diode 1 is arranged in the installing hole 22, the power connection equipment of its afterbody is connected with external circuit by through hole 21, for example common light emitting diode 1 is arranged on the circuit board, then draw lead on the circuit board, lead comes out from through hole 21, just can be connected with the external world easily, because the opening of through hole 21 is positioned at heat-radiating rod 2 sides, when whole illumination module was installed, this opening can directly be drawn out to lead the afterbody of whole lamp body over against the afterbody of street lamp, is convenient to be connected with the lead of electric pole; Heat-radiating rod 2 is positively connected with radiation panel 4, radiation panel 4 can increase the radiating effect of whole illumination module, the connected mode of itself and heat-radiating rod 2 can adopt common connected modes such as screw, screens, be provided with on radiation panel 4 and the corresponding opening 41 in installing hole 22 positions, the light source when light emitting diode 1 is worked so just can shine out by opening 41; Light emitting diode 1 the place ahead in installing hole 22 is provided with reflector 3, reflector 3 can strengthen illuminating effect, be provided with transmissive mirror 5 in reflector 3 the place aheads, to reach better illuminating effect, between the opening 41 of transmissive mirror 5 the place aheads and radiation panel 4, be pressed with the sealing ring 6 that rubber or other materials are made, so just make inner light emitting diode 1 element such as grade and the positive external world separate, reached waterproof effect.
Wherein as optimal way of the present invention, the described reflector 3 anterior outsides are provided with external screw thread, opening 41 rears of described radiation panel 4 are provided with and are raised with locating slot 42, be provided with the internal thread that matches and be connected with the external screw thread of reflector 3 in the locating slot 42, reflector 3 is installed together by screw thread and radiation panel 4, make both fixing more stable, and make that the sealing effectiveness of sealing ring 6 in transmissive mirror 5 the place aheads is better.
