Abstract

The utility model discloses an LED (light-emitting diode) ceiling lamp comprising a chassis, an inner tray, a transverse air-outlet fan module, a power supply, an LED lamp bead, an LED lamp bead aluminium base plate and an acrylic lamp shade, wherein the chassis is connected with the inner tray through a connecting copper column and a copper column screw; a cavity is formed between the chassis and the inner tray; the LED lamp bead aluminium base is fixed in a round hole in the middle of the inner tray through screws; the LED lamp bead is welded on the LED lamp bead aluminium base plate; the transverse air-outlet fan module is fixed on the LED lamp bead aluminium base plate through screws; the power supply is fixed on the inner tray through screws; the acrylic lamp shade is clamped and connected on a clamping tongue arranged at the edge of the chassis; an outer air flue, an air-inlet small hole and an air-outlet small hole are designed on the chassis; a radiating channel is formed by the chassis and the transverse air-out fan module which are matched with each other, so that a hot air flue and a cold air flue are separated; the transverse air-out fan module is used for extracting air and blowing out air; therefore, the radiating effect is very good, and the service life of the LED lamp bead is greatly prolonged.

Description

A kind of LED lamp affixed to the ceiling

Technical field

The utility model relates to a kind of light fixture, especially a kind of LED lamp affixed to the ceiling.

Background technology

Lamp affixed to the ceiling is the lighting of using always, is widely used in many places such as corridor in family and office space, hospital, school, hotel.Present lamp affixed to the ceiling all is that fluorescent lamp is done light source basically, have that power consumption is big, the life-span is short, colour rendering index is low, etc. shortcoming.

Advancing over one year also, the someone adopts LED to do the light emitting source of lamp affixed to the ceiling, but now the lamp affixed to the ceiling structure done of useful LED light emitting source be: in the housing of former fluorescent lamp formula lamp affixed to the ceiling, remove fluorescent tube, change an aluminium sheet or a pcb board that is complementary with the lamp affixed to the ceiling housing into, the led light source sheet or the some particle LED lamp pearl of some is installed on aluminium sheet or the pcb board uniformly.The LED lamp affixed to the ceiling disadvantage of this structure is that the heat that led light source sheet or lamp pearl produce all distributes in the housing of lamp affixed to the ceiling, makes that the temperature in the housing constantly raises, and consequently, causes the life-span of led light source sheet or lamp pearl to shorten greatly.

The utility model content

In view of problems of the prior art, the purpose of this utility model is to provide a kind of LED lamp affixed to the ceiling that can efficiently radiates heat.

Technical solution adopted in the utility model is: a kind of LED lamp affixed to the ceiling, comprise the chassis, inner pallet, horizontal air-out blower fan module, power supply, LED lamp pearl, LED lamp pearl aluminium base and acrylic lampshade, wherein chassis and inner pallet are by being connected the copper post and copper post screw links together, it between chassis and the inner pallet cavity, LED lamp pearl aluminium base is fixed on the middle circular hole of inner pallet by screw, the bead weld of LED lamp is connected on the LED lamp pearl aluminium base, laterally air-out blower fan module is fixed on the LED lamp pearl aluminium base by screw, power supply is fixed on the inner pallet by screw, the acrylic lampshade is connected on the block tongue of chassis edge setting, and the chassis is a truncated cone-shaped, the outside design has outer air channel, the center design has one group of air intake aperture, and the outward flange equal distribution has three groups of air-out apertures.

The beneficial effect that the technical scheme that adopts the utility model to provide can reach is: the air-out aperture of the outer air channel of designing on the chassis, the air intake aperture at center and edge designs, add horizontal air-out blower fan module and cooperate heat dissipation channel of composition with it, with hot and cold air channel separately, and with the heat radiation of taking out, dry of horizontal air-out blower fan module, radiating effect is very good, has prolonged the service life of LED lamp pearl greatly.

Fig. 2 is the utility model chassis structure schematic diagram.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is described in further detail:

Embodiment one:

As shown in Figure 1, be the utility model profile, a kind of LED lamp affixed to the ceiling, comprise chassis 8, inner pallet 1, horizontal air-out blower fan module 6, power supply 7, LED lamp pearl 9, LED lamp pearl aluminium base 10 and acrylic lampshade 11, wherein chassis 8 and inner pallet 1 are by being connected copper post 2 and copper post screw 3 links together, form the internal channel of a cavity between chassis 8 and the inner pallet 1 as heat radiation, chassis 8 is provided with an aperture and is used for drawing of power outlet 5, and rubber ring 4 is installed in its contact portion, avoid the wearing and tearing of power outlet 5, LED lamp pearl aluminium base 10 is fixed on the circular hole of inner pallet 1 centre by screw, LED lamp pearl 9 is welded on the LED lamp pearl aluminium base 10, laterally air-out blower fan module 6 is fixed on the LED lamp pearl aluminium base 10 by screw, power supply 7 is fixed on the inner pallet 1 by screw, acrylic lampshade 11 is connected on the block tongue of 8 edges, chassis setting, can avoid its loose or dislocation.

Embodiment two:

As shown in Figure 2, be the utility model chassis structure schematic diagram, chassis 8 is a truncated cone-shaped, and the outside design has outer air channel 12, the center design has one group of air intake aperture 13,, outward flange is evenly distributed with three groups of air-out apertures 14, adds horizontal air-out blower fan module and cooperates the unidirectional heat dissipation channel of composition with it, with hot and cold air channel separately, and with the heat radiation of taking out, dry of horizontal air-out blower fan module, radiating effect is very good, has prolonged the service life of LED lamp pearl greatly.
