Description

A kind of LED ceiling lamp

Technical field

A kind of LED is the utility model is related to, specifically a kind of LED ceiling lamp.

Background technology

As the negative effect caused by Global Greenhouse Effect constantly shows, every country all makees energy-saving and emission-reduction in the world By the major issue that must take into consideration in native economic development, LED lighting engineering is exactly to be arisen at the historic moment under this background An emerging power-saving technology.LED illuminating products have been had been applied in daily life at present, with developing rapidly for LED. There is the conventional light source that present white LED light source is compared long lifespan, solid state lighting to be hardly damaged, specular removal, mercury-free are environmentally friendly, antidetonation The advantages that, future will turn into third generation light source, will bring the revolution again of lighting field.Following lack be present in existing technology Point：1st, independent driving cost is high, 2, volume it is big, 3, voltage adaptation scope it is small, 4, security performance it is low.

Utility model content

The purpose of this utility model is to provide a kind of LED ceiling lamp, to solve the problems mentioned in the above background technology.

To achieve the above object, the utility model provides following technical scheme：

A kind of LED ceiling lamp, including upper lid, lower cover and PCB, it is described on be covered with 3 screwed holes, 3 screw threads 120 ° are spaced between hole, is distributed in equilateral triangle, is provided with circular protrusions in the middle part of upper lid, lower cover is identical with upper lid profile, identical bits Put and also be provided with screwed hole, lower cover is connected with upper lid by screw, and the circular inner sunken face of a circle, interior concave curved are additionally provided with lower cover 3 PCB vertical columns are additionally provided with the inside of face, 120 ° are spaced between 3 PCB vertical columns, in equilateral triangle Distribution, lower cover center are provided with curved inner surface groove, and lower cover bottom is additionally provided with alternating current wire casing, and PCB passes through PCB electricity Road plate vertical columns are fixed between lid and lower cover.

As preferred scheme of the present utility model：The PCB be provided with lens fixing hole, annular LED lamp group and Driving power.

As preferred scheme of the present utility model：The material of the inner sunken face is optical lens.

As preferred scheme of the present utility model：The circular protrusions are PC optical lenses.

As preferred scheme of the present utility model：The PCB is aluminium base.

Compared with prior art, the beneficial effects of the utility model are：1st, using Linear Driving scheme, save driving into This.2nd, reduce aluminium base board size, save aluminium base cost.3rd, light source module group 170-265V input voltage range, adapt to wider Scope range of the fluctuation of voltage.4th, agree with the lens of light source module group design, while solving luminous problem, can play explosion-proof and prevent touching The effect of electricity, increase security performance.

Embodiment

Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made The every other embodiment obtained, belong to the scope of the utility model protection.

Refer to Fig. 1-4, a kind of LED ceiling lamp, including upper lid, lower cover and PCB, it is described on be covered with 3 spiral shells 120 ° are spaced between 9,3 screwed holes 9 of pit, is distributed in equilateral triangle, circular protrusions 10, lower cover and upper lid are provided with the middle part of upper lid Profile is identical, and same position also is provided with screwed hole 1, and lower cover is connected with upper lid by screw, and circle circle is additionally provided with lower cover Inner sunken face 2, the inner side of inner sunken face 2 be additionally provided with 3 PCB vertical columns, 4,3 PCB vertical columns 4 it Between be spaced 120 °, be distributed in equilateral triangle, lower cover center is provided with curved inner surface groove 3, and lower cover bottom is additionally provided with alternating current Wire casing 5, PCB are fixed between upper lid and lower cover by PCB vertical columns 4.

PCB is provided with lens fixing hole 6, annular LED lamp group 8 and driving power 7.The material of inner sunken face 2 is Optical lens.Circular protrusions 10 are PC optical lenses.PCB is aluminium base.

Operation principle of the present utility model is：The inner sunken face 2 of lower cover, agree with the optical texture face of lamp bead arrangement, make collection Middle light emitting source uniformly dissipates light extraction.

Aluminium base（Pcb board）Vertical columns 4, agree with fixed light source with aluminium base.

Optical lens is designed in strict accordance with the size of optoelectronic integration light source module group, is solved light-source brightness and is excessively collected In.

1st, lens-shape is attractive in appearance, can annular arrangement light source of the fit diameter in 50-200mm uniformly dissipated

2, while solving light source light extraction, lens may also function as the effect of anti-explosion cover.In terms of security performance further Strengthen.

Curved inner surface groove 3, the component placement location of driving power part.

PCB：DOB light source module groups circuit runs drawing：Because circuit uses two sections of lighting modes.So module Applied voltage can reach 170-265VAC, can only be adapted to for single voltage lights relative to traditional linear circuit.Have Some superiority.
