Abstract
The utility model is a kind of flat lamp heat abstractor, comprise: the base plate be arranged in order, reflective sheeting, light guide plate, panel, light emitting source is fixed on light-guide edge, by frame by above-mentioned each module package together, composition is in flat flat lamp body, the sidewall of the frame of flat lamp also forms the heat sink extended obliquely, heat sink is curved, and the edge of the peak of heat sink flushes with the end face of frame.The utility model is formed with the edge of an arc in frame outside, make also can well keep the original style in roof during the single installation of flat lamp, and heat sink arc is upwards arranged, better achieve the function of heat radiation, rapider must by heat energy upwards water conservancy diversion discharging, and heat sink arc arranges the length also in a disguised form increasing heat sink, thus makes the area of heat sink larger, heat-dissipating space is also just larger, also can ensure good heat dispersion when ensure that long-time use.
Description
technical field:
The utility model relates to flat lamp field, particularly a kind of flat lamp heat abstractor.
background technology:
Application number is the Chinese patent of 201210162872.9, name is called a kind of flat lamp, disclose a kind of flat lamp structure, such structure makes area of dissipation increase, easy for installation, but single flat lamp is installed then not too attractive in appearance, and under long-time practicality, heat dispersion is still not enough, and at room temperature use 24 hours continuously, the surface temperature of frame can reach more than 60 DEG C.
utility model content:
The purpose of this utility model is exactly the deficiency for prior art, and provides a kind of flat lamp heat abstractor, well solves the overall style in destruction roof after installing in prior art, uses the problems such as poor heat radiation for a long time.
Technology solution of the present utility model is as follows:
A kind of flat lamp heat abstractor, comprise: the base plate be arranged in order, reflective sheeting, light guide plate, panel, light emitting source is fixed on light-guide edge, by frame by above-mentioned each module package together, composition is in flat flat lamp body, the sidewall of the frame of flat lamp also forms the heat sink extended obliquely, heat sink is curved, and the edge of the peak of heat sink flushes with the end face of frame.The edge of an arc is so just formed in frame outside, make also can well keep the original style in roof during the single installation of flat lamp, and heat sink arc is upwards arranged, better achieve the function of heat radiation, the heat energy that light emitting source is sent can according to the objective law of heat upwards ascension, rapider must by heat energy upwards water conservancy diversion discharging, and heat sink arc arranges the length also in a disguised form increasing heat sink, thus make the area of heat sink larger, heat-dissipating space is also just larger, also can ensure good heat dispersion when ensure that long-time use.
As preferably, heat sink has multi-disc, and multi-disc heat sink is molded on the sidewall of frame along frame short transverse uniform intervals, and the radian of each fin is all consistent with thickness, and the edge of the peak of each fin all flushes with the end face of frame.
As preferably, the radian of fin is 60 ° ~ 75 °, and fin has 3.The radian of fin is 60 ° ~ 75 ° spaces that not only can well expand heat radiation, also ensure that fin length, further ensures the effect of heat radiation.
As preferably, the ratio of the arc length of each fin is followed successively by 1:2:3 from top to bottom.Such ratio makes fin while having excellent heat dispersion performance, ensure that the utilization rate of material, controls the cost of product.
The beneficial effects of the utility model are:
The utility model is formed with the edge of an arc in the sidewall outside of frame, make also can well keep the original style in roof during the single installation of flat lamp, and heat sink arc is upwards arranged, better achieve the function of heat radiation, the heat energy that light emitting source is sent can according to the objective law of heat upwards ascension, rapider must by heat energy upwards water conservancy diversion discharging, and heat sink arc arranges the length also in a disguised form increasing heat sink, thus make the area of heat sink larger, heat-dissipating space is also just larger, also good heat dispersion can be ensured when ensure that long-time use.
