Description

LED ceiling lamp

Technical field

The utility model is related to ceiling lamp field, more particularly to a kind of LED ceiling lamp.

Background technology

LED ceiling lamp be it is a kind of using LED as light source, installed in house interior, the appearance design of lamp for top compared with It is flat, install and abut roof, as adsorbing on roof, therefore referred to as LED ceiling lamp, then have light efficiency height, the little power consumption, longevity of LED lamp bead Life length, easy to control, non-maintaining, safety and environmental protection is cold light source of new generation, than tubular energy-saving lamp power saving, and brightness is high, and light projector is remote, throws Optical property is good.

At present, universal LED ceiling lamp in order that LED ceiling lamp light efficiency is uniform, luminous diffusion and brightness are soft all can be LED ceiling lamp is provided with diffuser, and current diffuser generally has following two：（1）Independence is installed in every LEDs lamp bead Diffuser, to increase the beam angle of LED lamp bead, increase range of exposures, but this independent printing opacity is installed in single LEDs lamp bead Cover, causes that cost is higher, lamp assembled complex procedures, and diffuser easily comes off, and causes LED ceiling lamp mask to show light extraction Circle, influences light efficiency.（2）Lens are formed in diffuser correspondence LED lamp bead position by Shooting Technique, lamp assembled technique is reduced, But this mode causes to need to redesign diffuser per a LED ceiling lamp, increases research and development and production cost.

Utility model content

The purpose of this utility model is to overcome the deficiency that above-mentioned prior art is present, and provides that a kind of beam angle is big, light A kind of LED ceiling lamp that effect is uniform, assembling is easy, cost-effective.

What the purpose of this utility model was realized in.

A kind of LED ceiling lamp, including chassis, the wiring board with LED lamp bead, LED driver and diffuser, the wiring board It is fixed on LED driver on chassis, wiring board and LED driver electrical connection, the center of the diffuser is provided with just The axis hole run through in bearing, the both sides outer wall of diffuser is separately provided for the positioning lug of diffuser fixation, and printing opacity Cover surface is circumferentially formed thereon a circle annular protrusion, and diffuser back side correspondence annular protrusion position forms a ring annular groove, Diffuser is installed on below chassis, and LED lamp bead is placed in annular groove, and the light that LED lamp bead is produced passes through the annular of diffuser Projection is transmitted away.

Above-mentioned technical proposal can be also made to the following further improve.

As more specifically scheme, the positioning lug is provided with through hole, and chassis correspondence lead to the hole site is provided with lockhole, and screw is worn Cross through hole to lock onto in lockhole, realize that diffuser is fixedly connected with chassis.

As more specifically scheme, the diffuser be light transmittance between 80% to 90%, the light efficiency of light source is in 80LM/W To a kind of discoid diffuser of the high light-passing plastic particle of band between 120LM/W.

As more specifically scheme, the diffuser surface is frosting, and the diffuser back side is shiny surface.

As more specifically scheme, the annular groove is " U-shaped " groove, and the both sides inwall of " U-shaped " groove is that radian is consistent Smooth arc-shaped surface, the bottom wall of " U-shaped " groove is the consistent smooth arc surface of radian.

As more specifically scheme, the annular protrusion surface is coarse frosted arc surface, the peak of annular protrusion Distance is between 1.3 millimeters to 3 millimeters between the minimum point of annular protrusion.

As more specifically scheme, the annular groove diameter is consistent with LED lamp bead diameter.

The beneficial effects of the utility model are as follows：

The utility model diffuser is from interior toward outer lug, so that diffuser surface, which forms one, encloses annular protrusion, the diffuser back of the body Face forms a ring annular groove, diffuser and chassis connection, and LED lamp bead is placed in annular groove, and LED lamp bead produces light and passed through Annular protrusion is transmitted away, needs to compare in every LEDs lamp bead installation independent transparent covers compared to traditional LED ceiling lamp, this practicality Novel diffuser and chassis connection, all LED lamp beads are placed in annular groove, without installing independent transparent covers so as to save material simultaneously Cost is reduced, and installs more quick, simple.

Further, the utility model diffuser is the diffuser with high light-passing plastic particle, and the annular groove of diffuser For " U " type groove, when LED lamp bead is placed in annular groove, the light that LED is sent makes the light beam of LED lamp bead by annular groove Angle increases, and light efficiency is more uniformly distributed, and brightness is softer, improves the practicality of LED ceiling lamp.

Embodiment

Below in conjunction with the accompanying drawings and embodiment is further described to the utility model.

Embodiment, with reference to shown in Fig. 1 to Fig. 6, a kind of LED ceiling lamp, including chassis 1, the wiring board 3 with LED lamp bead 2, LED driver 4 and discoid diffuser 5.

The LED lamp bead 2 is along the circumferential direction uniformly arranged in assist side 3, and wiring board 3 and LED driver 4 electrically connect Connect, the control of LED driver 4 LED lamp bead 2 is extinguished or lighted.

The diffuser 5 be light transmittance 87%, a kind of high light-passing plastic particle of band of the light efficiency of light source in 110LM/W Diffuser, the center of diffuser 5 is provided with the axis hole 6 for being easy to bearing to run through, if user decorates to ceiling lamp, will Bearing with decorative article through axis hole 6 and fixation can, it is simple to operate.
