Abstract
The utility model relates to a round LED ceiling lamp which comprises a chassis and a lampshade, wherein an LED panel light-emitting module is arranged on the chassis, the LED panel light-emitting module comprises an annular base, a plurality of circles of LED beads are arranged on the annular base in a surrounding mode, the distance between every two adjacent circles of LED beads is 5.5-6.5mm, the transverse distances between the LED beads are decreased from inside to outside by 1.5-2.5mm, and the transverse distances of the beads of the first circle are 5.5-6.5mm; each circle of LED beads is divided into a first group and a second group by number, wherein the first group of lamp beads is connected with the second group of lamp beads in series, and the first group of lamp beads and the second group of lamp beads which are connected in series are connected to a constant flow source circuit in parallel. When the whole LED panel light-emitting module emits light, the light becomes weaker gradually from inside to outside, and the uniform degree and softness of the light are improved.
Description
Technical field
The utility model relates to a kind of round LED lamp affixed to the ceiling.
Background technology
Lamp affixed to the ceiling is arranged on ceiling, because light fixture top is more flat, near roof, installs, and similarly be to be adsorbed on roof, therefore be referred to as lamp affixed to the ceiling.Lamp affixed to the ceiling is installed simple and easy, simple and generous, is suitable for the decorative lightings such as household, public place, is very practical.The light source of general lamp affixed to the ceiling has common white bulb, fluorescent lamp, high-intensity gas discharge lamp, halogen tungsten lamp etc.But the utilization rate of electrical of white bulb, fluorescent lamp is low, and illumination effect is poor, and high-intensity gas discharge lamp, halogen tungsten lamp is expensive.Along with sending out of science and technology opened, the LED lamp cheap, that illumination effect is good is popularized gradually and is used.Good heat dissipation effect, LED cheap, that illumination effect is good is used the lamp source as lamp affixed to the ceiling.Existing lamp affixed to the ceiling LED panel light emitting module generally comprises aluminium base, with SMD method, a plurality of LED lamp pearl rings is located on aluminium base, and LED lamp pearl horizontal spacing and longitudinal pitch are fixed value.So, although LED panel light emitting module is Integral luminous, light is the soft degree deficiency of even degree all.
Summary of the invention
The utility model provides a kind of round LED lamp affixed to the ceiling, and it is good heat dissipation effect not only, cheap, and Integral luminous is effective, and high, the soft degree of light uniformity coefficient is high, free from glare.
The technical solution of the utility model is:
A kind of round LED lamp affixed to the ceiling, comprise chassis and lampshade, on described chassis, device has a LED panel light emitting module, described LED panel light emitting module comprises the annular pedestal, be equipped with some circle LED lamp pearls on described annular pedestal, described some circles LED lamp Zhu Quan is 5.5-6.5mm with the spacing between circle, the horizontal spacing between described LED lamp pearl by interior outward by 1.5-2.5mm apart from increasing progressively, the horizontal spacing between first circle LED lamp pearl is 5.5-6.5mm; Described LED lamp pearl is divided into one group and two groups by number, and described one group of LED lamp pearl and two groups of LED lamp pearls adopt and are connected in series respectively, and described one group of LED lamp pearl and the two groups of LED lamp pearls that are connected in series are parallel in constant-current source circuit.
Described annular pedestal is the annular aluminium base, and the thermal conductivity factor of described circular aluminum pedestal reaches more than 3.
Described LED lamp pearl is low-power LED.
Advantage of the present utility model: the spacing between the utility model circle and circle remains unchanged, change horizontal spacing between LED lamp pearl by interior outward by increasing progressively, while making LED panel light emitting module Integral luminous, light is by interior gradually gentle outward, so, LED panel light emitting module light uniformity coefficient after Integral luminous improves, soft degree improves, and not there will be dazzle; The utility model also has production technology to be simplified, in the simple and practical advantage of illumination application.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the utility model circuit theory diagrams.
The specific embodiment
For the ease of it will be appreciated by those skilled in the art that, now embodiment is described in further detail structure of the present utility model by reference to the accompanying drawings:
With reference to figure 1, a kind of round LED lamp affixed to the ceiling, comprise chassis 1 and lampshade 2, on described chassis 1, device has a LED panel light emitting module, described LED panel light emitting module comprises annular pedestal 3, be equipped with 4 circle LED lamp pearls 4 on described annular pedestal 3, described 4 circle LED lamp Zhu4Quan are 6mm with the spacings between circle, the horizontal spacing between described LED lamp pearl by interior outward by 2mm apart from increasing progressively, the horizontal spacing between first circle LED lamp pearl is 6mm.As shown in Figure 2: described LED lamp pearl is divided into one group and two groups by number, described one group of LED lamp pearl 4-1 and two groups of LED lamp pearl 4-2 adopt and are connected in series respectively, and described one group of LED lamp pearl 4-1 and the two groups of LED lamp pearl 4-2 that are connected in series are parallel in constant-current source 5 circuit.
Described annular pedestal 3 is the annular aluminium base, and the thermal conductivity factor of described circular aluminum pedestal reaches more than 3.
Described LED lamp pearl 4 is low-power LED (2835 0.02W), 150 altogether, be divided into one group and two groups with 75, and 75 LED lamp pearls of every group are connected in series respectively, then are parallel to together in constant-current source 5 circuit.The power of this constant-current source 5 is 30-36W, and 75 LED lamp pearls of every group are connected into the LED lamp string of high pressure, and the operating current of reduction LED lamp pearl for LED lamp pearl illuminating, is effectively alleviated its intensification to 35mA.Keep the spacing between 4 circle LED lamp Zhu Quan and circle constant, change horizontal spacing between LED lamp pearl 4 by interior outward by increasing progressively, while making LED panel light emitting module Integral luminous, light is by interior gradually gentle outward, so, LED panel light emitting module light uniformity coefficient after Integral luminous improves, soft degree improves, and not there will be dazzle.
The foregoing is only preferred embodiment of the present utility model, all equalizations of doing according to the utility model claim change and modify, and all should belong to covering scope of the present utility model.
