Description

LED downlight with integrated radiator

technical field

The utility model relates to an LED downlight, in particular to an LED downlight adopting an integrated radiator.

Background technique

Due to its small size, low power consumption, long service life, high brightness, low heat, environmental protection and other advantages, LED has been gradually popularized in daily life. For example, many downlights are now changed from traditional light sources to LED light sources, but because the LED light source itself has a problem of large heat accumulation, it is necessary to configure a special radiator, which greatly increases the volume of the downlight. The installation is inconvenient, and the efficiency of heat dissipation is not high.

Contents of the invention

In order to overcome the deficiencies of the prior art, the utility model provides an LED downlight with an integrated heat sink with high heat dissipation efficiency and small volume.

The technical scheme that the utility model solves its technical problem adopts is:

The LED downlight adopting an integrated radiator includes a downlight body, the downlight body includes a panel, an LED light source assembly and a radiator installed on the panel, a cavity is provided in the radiator, and the LED light source assembly Arranged in the cavity, several cooling fins are arranged on the outside of the heat sink, and the heat sink is an integral structure made of heat-conducting materials.

The LED light source assembly includes an LED light source, a reflective cup and a face ring. The face ring presses and installs the LED light source and the reflective cup into the cavity of the radiator, and the radiator is fixed to the panel through the face ring.

The LED light source is a COB light source.

Mounting shrapnels are arranged on both sides of the radiator.

The beneficial effect of the utility model is that: the downlight body includes a panel, an LED light source assembly and a radiator installed on the panel, a cavity is provided in the radiator, and the LED light source assembly is arranged in the cavity. There are several heat sinks on the outside of the radiator, and the radiator is an integrated structure made of heat-conducting materials. Since the LED light source assembly is directly arranged in the radiator, the radiator can be used for heat dissipation and can also be used as a lamp. The body structure greatly increases the heat dissipation area of the radiator, and can effectively and quickly conduct the heat generated by the LED light source to the entire radiator. The heat dissipation efficiency is high, and the volume of the downlight can be reduced, which is convenient for the installation and use of the downlight.

Detailed ways

Referring to Fig. 1 and Fig. 2, Fig. 1 and Fig. 2 are structural schematic diagrams of a specific embodiment of the present invention. As shown in the figure, the LED downlight using an integrated radiator includes a downlight body, and the downlight body includes The panel 2, the LED light source assembly and the radiator 1 installed on the panel 2. There is a cavity in the radiator 1, and the LED light source assembly is arranged in the cavity. The LED light source assembly includes an LED light source 31, The reflective cup 32 and the face ring 34, the face ring 34 presses and installs the LED light source 31 and the reflective cup 32 into the cavity of the radiator 1, and the radiator 1 is installed and fixed on the panel 2 through the face ring 34, Several cooling fins 11 are provided on the outside of the radiator 1, and the radiator 1 is an integrated structure made of heat-conducting materials such as copper and aluminum. Since the LED light source assembly is directly arranged in the radiator 1, heat dissipation The radiator 1 can be used for heat dissipation, and can also be used as a lamp body structure, which greatly increases the heat dissipation area of the radiator 1, and can effectively and quickly conduct the heat generated by the LED light source 31 to the entire radiator 3, with high heat dissipation efficiency. Moreover, the volume of the downlight can be reduced, and the installation and use of the downlight is convenient.

As shown in the figure, there are installation shrapnels 4 on both sides of the radiator 1, through which the downlight can be easily installed on the ceiling; in this embodiment, the LED light source 31 is a COB light source, with A more uniform light-emitting surface and better heat transfer, coupled with a special reflector 32, can further ensure that the lamp has a longer service life and light efficiency than traditional SMT. The above-mentioned COB light source is a commonly used light source in the LED industry. The package structure will not be described in detail here.

The above is a specific description of the preferred implementation of the present utility model, but the present invention is not limited to the described embodiments, and those skilled in the art can also make various equivalent deformations or modifications without violating the spirit of the present utility model. Replacement, these equivalent modifications or replacements are all included within the scope defined by the claims of the present application.
