Description

A kind of ceiling lamp

Technical field

The utility model relates to field of light fittings, in particular to a kind of ceiling lamp.

Background technique

Lamp has irreplaceable role in people's lives, from the LED light of pervious incandescent lamp till now, heat dissipation problem It is an eternal problem, lamp luminous natural will generate a large amount of heat, and how heat shed, while not influencing again The illuminating effect of lamp becomes the pursuit of Design of Luminaires person always.

For LED light, maximum pyrotoxin not instead of LED lamp bead, coupled driving circuit and power supply Circuit, if by power circuit and driving circuit with LED lamp panel is separated thus can be reduced to LED lamp bead illumination effect Influence, in addition, can also utilize in lamp space using come the heat dissipation effect that enhances LED light

Utility model content

The main purpose of the utility model is to provide a kind of by changing setting for power circuit, driving circuit and LED lamp panel Region is set to reduce power circuit and driving circuit fever and realize the ceiling of better illumination effect to the influence of LED lamp panel Lamp.

The utility model proposes a kind of ceiling lamps, including pedestal and lampshade, further include fixed bracket, and the fixed branch is set up It sets in chassis interior, and has one section of gap between the fixed bracket and the base bottom；Fixed rack upper surface part to Lower recess forms an annular groove, stud is provided on annular groove, it is solid that light-emitting LED lamp plate passes through screw thread between screw and stud It is scheduled on stud, recess forms a circular groove, power circuit and LED lamp panel driving electricity upwards among fixed bracket lower surface Road is arranged below circular groove, is provided with heat release hole below the chassis outer side face.

Preferably, the fixed bracket makes the fixed bracket be fixed on the bottom by the supporting block of the base side Above seat bottom.

Preferably, fixation is connected through a screw thread between the fixed bracket and the supporting block.

Preferably, the shape of the heat release hole is circle, and is divided into two rows and is arranged below the chassis outer side face.

Preferably, the base bottom is provided with the support of a support fixed power source circuit and LED light drive circuit Column.

The ceiling lamp of the utility model has the beneficial effect that

The ceiling lamp of the utility model includes pedestal, lampshade and includes fixed bracket, and fixed bracket is arranged in chassis interior, and There is one section of gap between fixed bracket and base bottom；Fixed rack upper surface part, which is recessed downwards, forms an annular groove, ring Stud is provided on connected in star, light-emitting LED lamp plate between screw and stud by being threadedly secured on stud, fixed bracket following table Recess forms a circular groove upwards among face, and power circuit and LED light drive circuit are arranged below circular groove, bottom Heat release hole is provided with below seat lateral surface.By the way that LED lamp panel and power circuit and LED light drive circuit are separated, thus Reduce LED lamp panel by heat is influenced additionally by be arranged groove, increase the contact area of LED lamp panel and air, thus The heat dissipation effect for greatly improving LED lamp panel, improves the illuminating effect of LED light.Heat release hole has been opened in pedestal side, and lower section Power circuit and LED light drive circuit are exactly among the access of air circulation, so that its heat dissipation effect is improved, and Improve heat dissipation effect while, reduce to the greatest extent lower section luminous component thickness, thus reduce cost and reduce lamp it is whole The thickness of body.

Detailed description of the invention

Figure label: 1, pedestal, 2, lampshade, 3, fixed bracket, 4, LED lamp panel, 5, power circuit and LED lamp panel driving Circuit, 6, stud, 7, heat release hole, 11, supporting block.

The embodiments will be further described with reference to the accompanying drawings for the realization, functional characteristics and advantage of the utility model aim.

Specific embodiment

It should be appreciated that specific embodiment described herein is only used to explain the utility model, it is not used to limit this Utility model.

Referring to figs. 1 to Fig. 3, an embodiment of the ceiling lamp of the utility model is proposed:

A kind of ceiling lamp, including pedestal 1, lampshade 2, fixed bracket 3, LED lamp panel 4 and power circuit and LED lamp panel are driven Dynamic circuit 5.The supporting block 11 of annular is provided in 1 inner side of pedestal, fixed bracket 3 is arranged in supporting block 11 and passes through spiral shell The mode of line connection is connected and fixed with supporting block, to be fixed on the base, fixed 3 bottom bottom of bracket is from 1 inside of pedestal A certain distance is still possessed in face bottom, flows for air, enhances heat dissipation effect.

Fixed 3 upper surface portion of bracket, which is recessed downwards, forms an annular groove, is provided with four studs 6 on annular groove, The mode that LED lamp panel 4 is connected through a screw thread is fixed on stud 6,4 upper surface highest point of LED lamp panel and fixed 3 upper surface of bracket Highest point is in same horizontal line, and other than the position connecting with stud 6, rest part all connects with air LED lamp panel 4 Touching reduces to improve the heat dissipation effect of LED lamp panel 4 because of the influence that LED lamp panel 4 itself is generated heat to its illuminating effect.

Recess forms a circular groove, power circuit and LED light drive circuit upwards among fixed 3 lower surface of bracket 5 are arranged below circular groove.And the mode being connected through a screw thread is connect with the support column on 1 medial surface bottom of pedestal, thus It is fixed on pedestal 1.By being arranged power circuit and LED light drive circuit 5 and LED lamp panel 4 in two places, thus Reduce because of the influence that power circuit and LED light drive circuit 5 generate heat to LED lamp panel 4, to enhance LED lamp panel 4 Heating effect.

The circular heat release hole 7 of two rows is provided with below 1 lateral surface of pedestal.Power circuit below 1 medial surface of pedestal and LED light drive circuit 5 is exactly among the access of air circulation, to improve its heat dissipation effect, and is improving heat dissipation effect While fruit, the thickness of lower section luminous component is reduced to the greatest extent, to reduce cost and reduce the thickness of lamp entirety.Separately Outside, in this way, also it is avoided that dust enters to reach LED lamp panel from heat release hole while heat release hole is set Situation, so that the durability of the ceiling lamp is promoted well.

The above is only the preferred embodiment of the present invention, and therefore it does not limit the scope of the patent of the utility model, Equivalent structure transformation made by using the description of the utility model and the drawings is applied directly or indirectly in other phases The technical field of pass, is also included in the patent protection scope of the utility model.
