Abstract
The utility model discloses a UVLED area source subassembly, including a plurality of encapsulation chips and radiator, be equipped with the heating panel on the radiator, a plurality of encapsulation chip equidistance are located on the heating panel, the heating panel is the curved surface, the heating panel includes central part and edge part, the central part is the plane, the edge part is greater than 90 with the contained angle of central part. The utility model provides a pair of UVLED area source subassembly, the intensity of illumination within range is high, has improved the utilization ratio of light, and the radiating effect is good.
Description
Technical field
The utility model relates to UVLED technical field, specifically, relates to a kind of UVLED surface light source component.
Background technology
Traditional ink and glue curing industry light source mainly use mercury lamp, but the shortcoming that mercury lamp has himself to exist, as power consumption, and need preheating after start, lamp tube service life is short, general at 800-1000 hours, wave-length coverage is large, and release heat is high, and curing efficiency is low, really only account for wherein sub-fraction for the ultraviolet light wave band effectively solidified, major part is infra-red radiation, easily makes the temperature distortion of thermal sensitivity workpiece, there is the pollutions such as mercury, tungsten heavy metal and toxic gas, burden is caused to surrounding environment, also can produce harmful ultraviolet.Therefore the high-pressure sodium lamp that ink and glue curing use at present is substituted by UVLED lamp gradually.
Existing LED area light source by chip package on heat sink, heat sink is generally plane, chip is uniformly distributed on heat sink, with the direction perpendicular to heat sink with 60-180 ° of full-shape luminescence, therefore the light-emitting zone of area source is trapezoidal, what heat sink edge chip sent examines outer half-angle due to overlapping with other chip or overlapping not less, causes this zonal ray insufficient strength, can not be done effective irradiation area by calculation.
Utility model content
The purpose of this utility model is to provide a kind of UVLED surface light source component, and effective irradiation area rate is high, and light utilization is high.
The technical scheme that disclosed in the utility model, UVLED surface light source component adopts is: a kind of UVLED surface light source component, comprise some packaged chips and radiator, described radiator is provided with heat sink, described some packaged chips are equidistantly located on heat sink, described heat sink is curved surface, described heat sink comprises central part and edge part, and described central part is plane, and the angle of described edge part and central part is greater than 90 °.
Preferably, described edge part is plane, and the angle of described edge part and central part is 120 ° to 150 °.
Preferably, described edge part connects with central part rounding.
Preferably, described edge part is smooth curved surface.
Preferably, UVLED surface light source component also comprises blower fan, and the side of radiator is located at by described blower fan.
Disclosed in the utility model, the beneficial effect of UVLED surface light source component is: the edge part of heat sink and the angle of central part are greater than 90 °, and make in light poly-, the intensity in illumination range is high, improves the utilization rate of light.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model UVLED surface light source component.
Detailed description of the invention
Below in conjunction with specific embodiment and Figure of description the utility model be further elaborated and illustrate:
Embodiment one: please refer to Fig. 1, a kind of UVLED surface light source component, comprise some packaged chips, radiator 3 and blower fan 4, described radiator 3 side is provided with heat sink, described some packaged chips are equidistantly welded on heat sink, and the opposite side of radiator is located at by described blower fan 4.
Described heat sink is curved surface, comprises central part 1 and edge part 2, and described central part 1 and edge part 2 are plane, and described central part 1 connects with edge part 2 rounding, and described central part 1 is 120 ° to 150 ° with the angle of edge part 2.
Described blower fan 4, for the cross-ventilation speed for improving in radiator 3, is heat sink fast cooling.
Because the angle of central part 1 and edge part 2 is 120 ° to 150 °, poly-in the light that packaged chip is launched, the intensity in illumination range is high, belongs to effective irradiation area, and therefore, the utilization rate of light is high.
Embodiment two: the difference of itself and embodiment one is, described heat sink is curved surface, also comprises central part and edge part, and wherein edge part is smooth curved surface, make in light poly-, the intensity in illumination range is high, improves the utilization rate of light.
Finally should be noted that; above embodiment is only in order to illustrate the technical solution of the utility model; but not the restriction to the utility model protection domain; although done to explain to the utility model with reference to preferred embodiment; those of ordinary skill in the art is to be understood that; can modify to the technical solution of the utility model or equivalent replacement, and not depart from essence and the scope of technical solutions of the utility model.
