Description

A replaceable panel dimmable downlight

technical field

The utility model relates to the field of lighting fixtures, in particular to a panel-adjustable downlight with a replaceable panel.

Background technique

Downlights have the advantages of soft light, bright, exquisite appearance, luxury, etc., and are widely used in interior decoration of homes, shops, businesses, and high-end hotels. At present, the downlight light source is mainly a traditional light source, because the traditional light source is a thermal light source, its luminous efficiency is low, its life is short, and its power consumption is relatively large. With the development of science and technology, the luminous efficiency and color rendering index of LED light sources are gradually improving, becoming the best choice to replace traditional light sources. The lighting market in the 21st century will be dominated by LED lighting.

Due to the long service life of LED, low energy consumption and significant energy saving, LED light sources have been widely used in daily life, such as lamp cups, spotlights, downlights, surface-mounted downlights, bulbs, wall washers, street lights, LED lighting fixtures such as car lights. However, with the increase in the number of LEDs in LED lamps and the development of high-power and high-brightness LEDs, the heat generated by LED lamps is gradually increasing. Therefore, how to quickly dissipate the heat generated by LED lamps has become a major problem that must be solved in current LED lamp technology.

Existing LED downlights are mainly composed of an aluminum alloy housing, an aluminum substrate, and LEDs mounted and fixed on the aluminum substrate. The aluminum substrate is installed in the housing and connected to the housing. The thermal conductivity of the shell itself can conduct away the heat generated by the LED when it is working.

Most of the existing LED downlights are non-dimmable products. LED downlights work at full load for a long time and often work at high temperatures, which affects the life of LED lamps and fails to achieve the best energy-saving purpose. The decorative appearance of the existing LED tube is not beautiful, and it is not suitable for use in high-end places.

Contents of the invention

Aiming at the deficiencies in the prior art, the purpose of this utility model is to provide a replaceable panel dimming downlight which can improve the installation method of the LED surface-mounted downlight, the panel can be replaced, and the LED surface-mounted downlight is more beautiful and convenient.

In order to achieve the above purpose, the technical solution adopted by the utility model is: a replaceable panel dimming downlight, including a lamp body, an LED light source, a control circuit board, a light-transmitting member and a decorative panel, and is characterized in that it also includes a Aluminum substrate and an LED driver, the LED light source is fixed on the aluminum substrate, electrically connected with the control circuit board, the aluminum substrate is fixed in the lamp body; the upper part of the lamp body is provided with a panel fixing groove, and the decorative panel is There is a buckle; the decorative panel is fixed on the panel fixing groove through the buckle; the lamp body is provided with a driver fixing hole, and the LED driver is electrically connected to the control circuit board, and the LED driver is fixed on the on the drive fixing hole.

Preferably, the LED driver is a dimming driver, connected to the LED light source to adjust the input voltage to change the brightness, so as to achieve more energy saving and environmental protection.

Preferably, the LED lamp body is a square lamp body or a round lamp body processed by a die-casting forming process, and the corresponding decorative panels and light-transmitting parts are square decorative panels, square light-transmitting parts or round Decorative panels, circular light-transmitting parts.

By adopting the above technical scheme, the replaceable panel dimming downlight of the utility model has beneficial effects as follows: the lamp body adopts a new die-casting forming process, and the LED light source is connected to the lamp body through the aluminum substrate to dissipate heat; the LED light source Through the matching LED dimming driver, the LED light source can emit light with different brightness, which is suitable for various occasions. Through the adjustment of brightness, the LED light source is not always in the full power state, so that the LED light source can achieve a longer service life and save more energy. In addition, the decorative panel and the lamp body are connected by buckles, so that the decorative panel can be replaced; it has the advantages of simple structure, more beautiful appearance and convenience.
