In order to make object of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
The embodiment of the present invention provides a kind of anti-dazzle heat-dissipating LED lamp, as Figure 1-4, comprises the housing 1 of an end opening, and the openend of housing 1 is connected with transparent member 2, thereby jointly forms the inner chamber of accommodating LED light source 4.In this inner chamber, multiple LED light sources 4 are arranged on housing 1 by radiator structure 3, simultaneously for LED light source 4 provides the power module 5 of voltage transitions and be also arranged in inner chamber by radiator structure 3 for LED light source 4 provides the current-limiting resistance 6 of overcurrent protection.Power module 5 can convert the alternating current of input or direct current to LED light source 4 applicable electric current, and it is excessive that current-limiting resistance 6 can be used for preventing flowing through the electric current of LED light source 4, for ease of observing, the half of this light fixture is only shown in Fig. 1.
Refer to shown in Fig. 2 and Fig. 4, housing 1 bottom shape is round rectangle, sidewall upwards extends perpendicular to bottom surface, and form circle first flanging 101 at housing 1 openend outward, wherein the first flanging 101 is parallel to bottom surface, and forms a upwardly extending circle position-limited edge 102 in the outer of the first flanging 101.
Transparent member 2 adopts makrolon material to make fairshaped (curved surface) cover body and makes it to have good anti-dazzle effect, shape is centrosymmetric, its edge also forms circle second flanging 201 of outward, as shown in Figure 2, the cross section of the second flanging 201 is " several " font, when installation by the second flanging 201 and the corresponding laminating of the first flanging 101 on housing 1, and the second flanging 201 also with the outer of the first flanging 101 on position-limited edge 102 fit.Position-limited edge 102 can limit the slip of transparent member 2 with respect to housing 1, the first flanging 101 and the second flanging 201 are fastened to transparent member 2 is fixed on housing 1 with multiple buckles, the setting of second flanging 201 of " several " font can make the relative housing 1 of transparent member 2 firmly fixing, can not affect illuminating effect by relative sliding.
In transparent member 2, be added with organic light diffusing agent, can select organic light diffusing agents such as acryl type, styrene type, acrylic resin type, light transmittance is high, repeatedly refraction occurs when the light that LED light source 4 sends passes through transparent member 2 makes light become soft, floodlight through transparent member 2 makes spot light become area source, as shown in Figure 6, by seeing in Fig. 6, the light that this light fixture sends has good antiglare effect to its distribution curve flux figure after the floodlight of transparent member 2.
Shown in Fig. 3 is that the embodiment of the present invention is removed the anti-dazzle heat-dissipating LED lamp structural representation after transparent member, and for the ease of observing, Fig. 3 only illustrates the half of this light fixture equally.
Shown in figure 5 to Fig. 7, the radiator structure 3 of this anti-dazzle heat-dissipating LED lamp comprises heat sink 31 and aluminium base 32, and as shown in Figure 6, heat sink is shaped as " work " font, and its area of dissipation is larger, can improve radiating efficiency.
As shown in Figure 7, multiple LED light sources 4 are fixed on aluminium base 32, and are in line and arrange on aluminium base 32.Multiple LED light sources 4 are to be uniformly-spaced evenly distributed on aluminium base 32 in the present embodiment, make each LED light source 4 and adjacent LED light source 4 have a determining deviation, thereby improve radiating efficiency.Certain multiple LED light source 4 also can be arranged to other distribution mode that is conducive to heat radiation on aluminium base 32.LED light source 4 can be mounted on aluminium base 32, also can internal thread be set on aluminium base 32 LED light source 4 is screwed onto on aluminium base 32.
As shown in Figure 5, radiator structure 3 comprises two aluminium bases 32, article two, aluminium base 32 is fixedly mounted on a face of heat sink 31 side by side, in the middle of two aluminium bases 32 on heat sink 31 these faces, be also fixed with power module 5 and current-limiting resistance 6, can adopt and aluminium base 32, power module 5 and current-limiting resistance 6 are fixed on heat sink 31 as the mode such as screw fastening, buckle, the bottom surface laminating of heat sink 31 another sides and housing 1.Aluminium base 32 and heat sink 31 form radiator structure 3, radiator structure 3 entirety are fixedly mounted on lamp casing 1 bottom surface, the present embodiment is to adopt screw radiator structure 3 to be screwed onto on the bottom surface of housing 1, can certainly adopt and radiator structure 3 is fixed on the bottom surface of housing 1 as alternate manners such as buckles.
Preferably, in order to improve radiating efficiency, between aluminium base 32 and heat sink 31, scribble uniformly thermal grease, in the present embodiment, adopt heat-conducting silicone grease that heat conductivility is good as thermal grease, can certainly select suitable material that other heat conductivility is good as thermal grease.Because aluminium sheet has good heat conductivility, in the present embodiment, aluminium base 32 and heat sink 31 are made by the aluminium sheet of bending and molding, and material selection 1016 aluminium sheets can certainly select other materials with good heat conductive performance to make.The radiating principle of radiator structure 3 is, the heat that LED light source 4 produces, be transmitted on heat sink 31 by aluminium base 32, be transmitted on housing 1 by heat sink 31 again, the heat that power module 5 and current-limiting resistance 6 produce is directly transferred on housing 1 by heat sink 31, be dispersed in air by housing 1 again, thereby reach desirable radiating effect.
The radiating effect test data of this anti-dazzle heat-dissipating LED lamp is as shown in the table:
The environmental condition of testing in upper table is that environment temperature is 40 DEG C, relative humidity is 38%, mean temperature to the LED light source 4 in four anti-dazzle heat-dissipating LED lamps is tested, test respectively LED light source 4 initial temperatures and continued to light 2 hours, temperature after 4 hours and 5 hours, continuing to light 2 by the LED light source 4 in the known anti-dazzle heat-dissipating LED lamp provided by the invention of data in table, 4, after 5 hours, its temperature raises and is all no more than 25 degrees Celsius, and it continues for a long time to light temperature afterwards and is no more than 60 degrees Celsius, and common LED light source 4 generally can normally be worked during lower than 70 degrees Celsius in temperature, therefore this time test proves that this anti-dazzle heat-dissipating LED lamp has good heat dispersion.
The above embodiment has only expressed preferred embodiments of the present invention, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
