Abstract

The utility model belongs to the technical field of illumination, in particular to an LED (light emitting diode) ceiling lamp. The LED ceiling lamp is formed by combining a plurality of modules; each module comprises an inner-ring lamp panel, an outer-ring lamp panel, a substrate and an LED luminous chip, wherein the section of the substrate is a triangular or trapezoidal strip; the surface of the bottom edge of the substrate is arranged and fit on the top surface of the ceiling lamp; the inner-ring lamp panel and the outer-ring lamp panel are respectively arranged on surfaces of two waist edges of the substrate; and the LED luminous chips are respectively arranged on the inner-ring lamp panel and the outer-ring lamp panel. The LED ceiling lamp disclosed by the utility model has the advantages that the LED ceiling lamp keeps the luminous evenness of the ceiling lamp, waste on rays by back lighting is reduced, and therefore the manufactured ceiling lamp saves energy for more than 40% if being compared with a ceiling lamp manufactured by a common annular fluorescent lamp.

Description

A kind of LED lamp affixed to the ceiling
Technical field
The utility model belongs to lighting technical field, is specially a kind of LED lamp affixed to the ceiling.
Background technology
The advantage of lamp affixed to the ceiling is that light-emitting area is big, thin thickness, easy for installation, is one of main light fixture of urban family illumination.At present on the market the lamp affixed to the ceiling overwhelming majority adopts the annular daylight lamp pipe as light source, has moderate cost, than incandescent lamp energy-saving advantages.
Because the annular daylight lamp pipe is luminous around the circumference, thus not only front light homogeneous and bright of lamp affixed to the ceiling that it does light source adopted, and also homogeneous and bright relatively of light all around.But lampshade face institute isolychn dorsad has only by base plate reflecting part light effectively, and the utilization rate of this part light is lower.
Along with the maturation of LED white light technology, LED in the application of illuminator also more and more widely.The advantage of LED illumination be the life-span long, light efficiency is high, lighting angle is at an in-plane, luminous utilization rate is higher.The way that LED commonly used substitutes annular lamp tube be directly with the bead weld of LED lamp on the loop line plate, be installed in again in the lamp affixed to the ceiling, promptly comprise by base, lampshade, led light source, LED power supply, see shown in Figure 1.The light efficiency utilization rate of the lamp affixed to the ceiling of working it out like this is high, but illumination effect is bad, because only near the place of loop line Board position, luminous brighter, there is tangible dark space in other places, and the light efficiency of side is poorer.
Summary of the invention
The purpose of the utility model is to provide the LED that a kind of life-span is long, light efficiency is high lamp affixed to the ceiling.
The LED lamp affixed to the ceiling that the utility model provides is made up of base, lampshade, led light source, LED power supply, wherein; Said led light source is made up of a plurality of led module splicings; Each led module comprises inner ring lamp plate (wiring board) 1, outer ring lamp plate (wiring board) 2, pedestal 3 and LED luminescence chip 4.Wherein, said pedestal 3 is triangle or trapezoidal rectangular (for example aluminium section bar etc.) for the cross section, and its bottom surface is settled and is fitted in lamp affixed to the ceiling base (being end face); Said inner ring lamp plate 1 is separately positioned on the inclined-plane, pedestal 3 both sides with outer ring lamp plate 2; Said LED luminescence chip 4 is separately positioned on inner ring lamp plate 1 and the outer ring lamp plate 2.See shown in Figure 2.
In the utility model; The led light source of above-mentioned led module splicing being formed the lamp affixed to the ceiling that adapts to different shape; For example: circular arc type, polygon (as square, regular hexagon) or other shapes, and each led module is electrically connected, form the special-purpose led light source of a lamp affixed to the ceiling.Like Fig. 3 is circular lamp affixed to the ceiling led light source, and Fig. 4 is square lamp affixed to the ceiling led light source.
In the utility model, the length of said pedestal 3 is 10mm~1000mm, and pedestal 3 sides (being the side of triangle or trapezoid cross section) length is 5mm~50mm, and the angle of pedestal 3 two sides is 90 degree~165 degree.
In the utility model, the quantity of the above LED luminescence chip (4) of the lamp plate of each led module is 1~100.
The utility model, the angle of said inner ring lamp plate 1 and outer ring lamp plate 2 makes the led light source that is placed in that 2 light emission directions arranged.Inner ring is strengthened lamp affixed to the ceiling central area luminous intensity, and the luminous intensity of lamp affixed to the ceiling lateral side regions is strengthened in the outer ring.
The advantage of the utility model is to make the LED lamp affixed to the ceiling both to keep the luminous uniformity of lamp affixed to the ceiling, has reduced again and has carried on the back luminous waste to light, and the lamp affixed to the ceiling that the lamp affixed to the ceiling of processing is like this processed than common annular daylight lamp is energy-conservation more than 40%.
Description of drawings
Fig. 1 is existing LED lamp affixed to the ceiling structural diagrams.
Fig. 2 is the led module structure chart of the utility model.
Fig. 3 is the round LED lamp affixed to the ceiling diagram of the utility model.
Fig. 4 is the square LED lamp affixed to the ceiling diagram of the utility model.
The specific embodiment
Embodiment:
Circular lamp affixed to the ceiling with a 18W is an example, and its luminosity is equivalent to the luminosity of the lamp affixed to the ceiling that the common annular daylight lamp of the T8 size of 36W processes, and the lamp affixed to the ceiling that uniformity of luminance effect and common annular daylight lamp are processed is basic identical.
At first in the individual module, it is leg-of-mutton aluminium section bar that pedestal is adopted as the cross section, its section triangle size base length 20 mm, and angle is 120 degree between the two waist limits, aluminium section bar length is 55 mm; Inner ring lamp plate and outer ring lamp plate are separately positioned on the face on pedestal two waist limits; 3 LEDs luminescence chips respectively are set on inner ring lamp plate and the outer ring lamp plate.
Then 12 above-mentioned modules are connected combination through electric wire from beginning to end, the face on the aluminium section bar base of the LED lamp affixed to the ceiling after the combination is settled be fitted in the lamp affixed to the ceiling end face; Draw electric wire and connect the lamp affixed to the ceiling power supply.
