Description

A LED ceiling lamp

technical field

The utility model relates to a lamp, in particular to an LED ceiling lamp. the

Background technique

Ceiling lamps are commonly used lighting fixtures, widely used in homes and offices, hospitals, schools, hotel corridors and many other places. The current ceiling lamps are basically fluorescent lamps as lighting sources, which have disadvantages such as high power consumption, short lifespan, and low color rendering index. the

In the past year, some people have also used LED as the light source of the ceiling lamp, but now the structure of all the ceiling lamps made of LED light source is: in the shell of the original fluorescent lamp type ceiling lamp, the fluorescent tube is removed and replaced with a piece that matches the shell of the ceiling lamp. A matching aluminum plate or PCB board, and a certain number of LED light source sheets or dot particle LED lamp beads are evenly installed on the aluminum plate or PCB board. The biggest disadvantage of the LED ceiling lamp with this structure is that all the heat generated by the LED light source sheet or lamp beads is dissipated in the shell of the ceiling lamp, so that the temperature in the shell continues to rise. As a result, the LED light source sheet or lamp beads Life expectancy is greatly shortened. the

Utility model content

In view of the problems existing in the prior art, the purpose of the utility model is to provide an LED ceiling lamp capable of effectively dissipating heat. the

The technical solution adopted by the utility model is: an LED ceiling lamp, including a chassis, an inner tray, a horizontal air outlet fan module, a power supply, LED lamp beads, an LED lamp bead aluminum substrate and an acrylic lampshade, wherein the chassis and the inner tray pass through The connecting copper column and the copper column screw are connected together. There is a cavity between the chassis and the inner tray. The LED lamp bead aluminum substrate is fixed on the round hole in the middle of the inner tray by screws, and the LED lamp bead is welded on the LED lamp bead aluminum substrate. The horizontal air outlet fan module is fixed on the aluminum substrate of the LED lamp bead by screws, the power supply is fixed on the inner tray by screws, the acrylic lampshade is clipped on the tabs set on the edge of the chassis, and the chassis is a circular frustum, and the outside is designed with external wind There is a set of air inlet holes in the center, and three sets of air outlet holes are evenly distributed on the outer edge. the

The beneficial effects that can be achieved by adopting the technical solution provided by the utility model are: the outer air duct designed on the chassis, the air inlet hole in the center and the air outlet hole designed on the edge, plus the horizontal air outlet fan module and it Cooperate to form a heat dissipation channel, separate the cold and hot air channels, and use the horizontal air outlet fan module to draw and blow heat to dissipate heat. The heat dissipation effect is very good, which greatly prolongs the service life of the LED lamp beads. the

Detailed ways

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

Embodiment one:

As shown in Figure 1, it is a sectional view of the utility model, an LED ceiling lamp, including a chassis 8, an inner tray 1, a horizontal air outlet fan module 6, a power supply 7, LED lamp beads 9, LED lamp beads aluminum substrate 10 and Acrylic lampshade 11, in which the chassis 8 and the inner tray 1 are connected together by connecting copper pillars 2 and copper pillar screws 3, a cavity is formed between the chassis 8 and the inner tray 1 as an inner channel for heat dissipation, and a small hole is provided on the chassis 8 It is used to lead out the power lead wire 5, and a rubber ring 4 is installed on its contact part to avoid the wear of the power lead wire 5. The LED light bead aluminum substrate 10 is fixed on the round hole in the middle of the inner tray 1 by screws, and the LED light bead 9 is welded on the LED lamp bead aluminum substrate 10, the horizontal air outlet fan module 6 is fixed on the LED lamp bead aluminum substrate 10 by screws, the power supply 7 is fixed on the inner tray 1 by screws, and the acrylic lampshade 11 is clamped on the edge of the chassis 8 On the set tab, it can prevent it from loosening and falling off. the

Embodiment two:

As shown in Figure 2, it is a schematic diagram of the chassis structure of the utility model. The chassis 8 is in the shape of a truncated cone, and an outer air duct 12 is designed on the outside, and a group of small air inlet holes 13 are designed in the center, and three groups of small air outlet holes are evenly distributed on the outer edge. 14. In addition, the horizontal air outlet fan module cooperates with it to form a one-way heat dissipation channel, which separates the cold and hot air channels, and uses the horizontal air outlet fan module to draw and blow heat to dissipate heat. The heat dissipation effect is very good, and the LED lamp is greatly extended. lifespan of the beads. the
