Compared to prior art, each light source of the utility model LED lamp affixed to the ceiling adds that the lens of different angles or the light source having add that lens have does not add lens, makes each light source have different rising angles, thereby makes whole bright dipping more even.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model LED lamp affixed to the ceiling one embodiment.
Fig. 2 is the structural representation of another embodiment of the utility model LED lamp affixed to the ceiling.
The specific embodiment
Below with reference to the drawings and the specific embodiments, the utility model is elaborated.
The utility model LED lamp affixed to the ceiling forms by some LED modules are assembled, can, by the LED module 10 of varying number and different assembled arrangement modes, form the lamp affixed to the ceiling of different profiles, different capacity.
As shown in Figure 1, in the present embodiment, described LED lamp affixed to the ceiling forms by 3 LED modules 10 are assembled, and monnolithic case is circular.Each LED module 10 comprises a circuit board 12 and is installed on the some light sources 14,16 on described circuit board 12.Preferably, the utility model is usingd LED lamp pearl as light source, and power is 0.1-8W.Described light source 14,16 can have identical or different power, also can have identical or different rising angle.Each light source 14,16 includes single or plurality of LEDs lamp pearl, and the power of the LED lamp pearl of each light source 14,16 can be identical, also can be different.For adjusting the rising angle of described light source 14,16, on described light source 14,16, be provided with different lens, or part light source light source 14,16 is provided with lens and does not add lens on part light source 14,16.
In the present embodiment, each LED module 10 is provided with two kinds of light sources, i.e. the first light source 14 and secondary light source 16, and the quantity of described the first light source 14, secondary light source 16 is identical, but power is different.In the present embodiment, the power of described the first light source 14 is less than the power of secondary light source 16, the first light source (low power light source) 14 arranges near the center of lamp affixed to the ceiling relatively, secondary light source (powerful light source) 16 is relatively near the edge of lamp affixed to the ceiling, arrange around described the first light source 14, a little less than avoiding the excessive and marginal portion light intensity of lamp affixed to the ceiling central light strength too.Preferably, the power of first light source 14 at close lamp affixed to the ceiling center is 0.1-5W, and the power of peripheral secondary light source 16 is 0.5-8W.In other embodiments, the power of described the first light source 14 also can be greater than the power of secondary light source 16, and the quantity of described the first light source 14, secondary light source 16 also can be different.
In the present embodiment, described the first light source 14, on secondary light source 16, be equipped with lens, but the rising angle of the lens on the first light source 14 and secondary light source 16 has certain difference, particularly, the rising angle of the lens on described the first light source 14 is 0-280 °, and the rising angle of lens on secondary light source 16 is greater than the rising angle of the lens of the first light source 14, for 0-359 °, thereby the light that secondary light source 16 sends passes through to penetrate after be equipped with lens the light that is greater than the first light source 14 to the rising angle outside lamp affixed to the ceiling to be penetrated to extraneous rising angle after the lens on it, thereby make the bright dipping at each position of lamp affixed to the ceiling more even, avoid light to concentrate the core by lamp affixed to the ceiling to penetrate.Understandably, in certain embodiments, can only on the first light source 14, lens be set, and on secondary light source 16, lens be set.
Be illustrated in figure 2 the schematic diagram of another embodiment of the utility model LED lamp affixed to the ceiling, be provided with equally the first light source 14, 16 two kinds of light sources of secondary light source, the first light source 14 is near the center of described lamp affixed to the ceiling, secondary light source 16 arranges around the first light source 14, difference is, the power of the present embodiment LED lamp affixed to the ceiling is large compared with the first embodiment, described light source 14, total quantity of 16 is greater than light source 14 in the first embodiment, 16 quantity, and in the present embodiment, the quantity of secondary light source 16 is greater than the quantity of the first light source 14, because the power of secondary light source 16 is larger, use more secondary light source 16 to promote on the whole the power of lamp affixed to the ceiling.That is to say, the difference of arranging etc. by quantity, the position of various Different Light 14,16, can form the light fixture of different capacity, due to the power of used light source 14,16,, the configuration of lens has guaranteed the uniformity of light that of lamp affixed to the ceiling, avoid the problems such as conventional lamp bright dipping is irregular, light intensity is inadequate.Understandably, the utility model LED lamp affixed to the ceiling is not limited to use two kinds of light sources 14,16, as there being in certain embodiments the 3rd, the 4th light source etc., power described the 3rd, the 4th light source can be identical with first, second light source 14,16, also can be different; Three, on the 4th light source, can be provided with lens and also lens can be set, establish in lensed situation, the rising angle of lens can be identical with first, second light source 14,16, also can be different.
It should be noted that; the utility model is not limited to above-mentioned embodiment; according to creative spirit of the present utility model; those skilled in the art can also make other variations; the variation that these are done according to creative spirit of the present utility model, within all should being included in the utility model scope required for protection.
