Abstract

The utility model discloses a ceiling lamp which comprises an LED component, a radiator, a lampshade and a reflecting shade. The light emitted by the LED component is emitted through the highly transparent acrylic lampshade and is transformed from direct light into diffuse reflection light under the action of the reflecting shade which is coated with a high-diffuse-reflectance coating. The light transmittance of the lampshade can reach more than 95%, and the reflectivity of the coating of the reflecting shade can also reach more than 95%, so that the purposes of being high in efficiency and saving energy are achieved. On one hand, compared with a traditional direct-radiation lamp, the lighting effect of the ceiling lamp can be improved by more than 10%; on the other hand, the light emitted by the LED component becomes uniform, mild and free of dazzling after being reflected through the reflecting shade, so that the lighting effect is effectively improved, and eyesight can be protected.

The specific embodiment

With reference to figure 1, Fig. 2 and Fig. 6, Fig. 1 is for to see that from oblique below the present embodiment structure of ceiling-mounted lamp schematic diagram, Fig. 2 are the present embodiment lamp affixed to the ceiling front view; Fig. 6 is mounting structure explosive view.In addition, it should be noted that take after lamp affixed to the ceiling is installed on ceiling in the present embodiment orientation is reference.

As above shown in each figure, the present embodiment lamp affixed to the ceiling comprises LED assembly, radiator, lampshade and reflection shield.

Described LED assembly 2 comprises aluminium base and is arranged on the some LED lamp pearls on aluminium base, and the present embodiment aluminium base, for annular (be certainly not limited to annular, also can be the square of hollow, specifically can make as required), is sleeved on an axis.

With reference to figure 3 and Fig. 4, described radiator comprises radiator body 1 and radiator cover, and described radiator cover comprises cover 7 at the bottom of the radiator that is set with radiator body and is positioned at the dust cover 9 at radiator top.Described dust cover integral body in the form of a ring, inner periphery has bend vertically upward upper, and along 9-1(, it acts on follow-up introduction), neighboring has the lower to 9-2 of a bending vertically downward, after radiator cover installs, describedly along 9-2, cover cover 7 at the bottom of described radiator down, and along covering at the bottom of 9-2 and radiator between 7 lateral wall, form airflow gap A down; At the bottom of described radiator, the bottom even of cover 7 is provided with some passage 7-1.Thermolysis has been played in the passage 7-1 that at the bottom of radiator, cover is offered and above-mentioned airflow gap A acting in conjunction, principle is as follows: air enters from passage 7-1, through radiator body 1, and then flowed out a cyclic process from airflow gap A, by circulation of air, can take away the heat that LED lamp distributes, simultaneously dust cover 9 effectively prevents that dust from falling into and on radiator, plays dustproof and cleaning action.

Described reflection shield 12 comprises a 12-1 of back taper portion and is connected to the block edge 12-2 on the edge, surrounding of this tapered portion, and the present embodiment block edge 12-2 face is the conical surface, and integral body is the round platform of a hollow, mainly plays effect reflective and that block dust.In order to improve reflectivity and scattered power, on the inner surface of described reflection shield 12, scribble high diffuse reflectance coating, the 12-1 of back taper portion surface and block edge 12-2 lower surface all scribble high diffuse reflectance coating, and its overall reflectivity is reached more than 95%.It should be noted that the present embodiment reflection shield and radiator all can be out of shape and beautify according to the requirement of luminous intensity distribution and decoration, as can be changed into arc, ellipse and increasing pattern, pendant etc.

Ordinary straight shot-light tool is to reach to reduce the effect of dazzling light, must use frosted lampshade or be added with the lampshade of light diffusing agent, cause lampshade efficiency at least to decline 10%, the present embodiment lampshade 8 adopts high transparent acrylic to make, light transmittance is up to more than 95%, thereby with less LED, send stronger light, increased light efficiency, realized energy-saving effect.The present embodiment lampshade 8 is hemispherical, certainly also can be arranged to as required square or semielliptical shape.After whole lamp affixed to the ceiling installs, described lampshade bottom is upper along coordinating with described dust cover, can effectively prevent that dust from entering in LED assembly or entering in radiator.

During installation, with reference to figure 6, radiator body 1 is packed at the bottom of radiator, in cover, LED assembly is placed in to radiator body 1 top, again dust cover 9 is passed from axis 5, be shelved on radiator body 1, after loading onto radiator pad 3, pass through nut 10 integral assemblings on axis 5, the present embodiment lampshade 8 is fixed on axis 5, then by screw 6, the above-mentioned parts integral body installing of having overlapped is fixed on to reflection shield bottom, again radiator cover shutoff 11 is blocked to bottom nut 10, whole lamp installation is good, when needs are installed on ceiling by lamp affixed to the ceiling, only need be fixed to ceiling by installing rack 4.Certain erection sequence is not limited to above-mentioned concrete, and practical operation can be determined according to operating personnel's custom.

Finally it should be noted that: above embodiment only, in order to the technical solution of the utility model to be described, is not intended to limit; Although the utility model is had been described in detail with reference to previous embodiment, those of ordinary skill in the art is to be understood that: its technical scheme that still can record aforementioned each embodiment is modified, or part technical characterictic is wherein equal to replacement, for example, only need change installing rack into suspension ring, can become pendent lamp; And these modifications or replacement do not make the essence of appropriate technical solution depart from the spirit and scope of each embodiment technical scheme of the utility model.
