Abstract

An LED lighting down lamp comprises a lamp body (1) and a driver (2), wherein the lamp body (1) is connected with the driver (2) by a turnover piece. The turnover piece comprises an upper hinge (3) and a lower hinge (4). The upper hinge(3) is fixedly connected with the driver (2), and the lower hinge (4) is fixedly connected with the lamp body (1). The upper hinge (3) is rotatablely connected with the lower hinge (4). The turnover piece can be used for adjusting the position of the driver (2) so that the driver (2) can move toward or away from the lamp body (1). Such design is flexible. The height requirement of the suspended ceiling can be effectively reduced, and a wide and comfortable living space is created for the user. In addition, when the driver (2) is overturned away from the lamp body (1), the driver (2) will not be baked by the heat generated during the operation of the down lamp, and the normal operation of the driver (2) can be protected.

Description

LED lighting downlight

Technical field

The utility model relates to an LED downlight, in particular to an LED lighting downlight which can adjust the height of the lamp body with the height of the ceiling.

Background technique

As is known to all, the existing conventional downlights and commonly used LED downlights, the height of the whole lamp body is generally high, and the height requirement for the ceiling of the ceiling is also high; for the user installation and use, the height of the ceiling is required. The height of the lamp body is high, and the ceiling is also required to be high, which lowers the height of our overall room. The height of the room is lowered, which makes it easy for people to feel a sense of pressure; and the general LED downlights are too far forward, which is prone to glare and glare. , hurt the eyes, easy to damage our eyes.

Technical solution

The utility model overcomes the deficiencies in the prior art mentioned above, and provides an LED lighting downlight which is flexible and variable and can effectively reduce the ceiling height requirement of the ceiling.

The technical solution of the utility model is realized as follows:

An LED lighting downlight comprises a lamp body and a driver, wherein the lamp body and the driver are connected by a flipping member, the flipping member comprises an upper hinge and a lower hinge, the upper hinge is fixedly connected with the driver, and the lower hinge It is fixedly connected to the lamp body, and the upper hinge and the lower hinge are rotationally connected. Preferably, the upper hinge and the lower hinge are connected by a pivot.

Preferably, the upper hinge is fixedly connected to the bottom surface of the driver, and the lower hinge is fixedly connected to the side surface of the lamp body.

Preferably, the fixed attachment means is welded or riveted or connected by screws. In the past, the height of the whole lamp body of the downlight was generally high, and the height requirement for the ceiling of the ceiling was also high, and the illuminating surface was too apt to generate glare. The reflector was generally made of aluminum oxide and plastic material, and there were many processes. A series of defects such as high cost and low reflectivity. Preferably, the lamp body comprises a heat sink, a reflector and a front frame, a hollow cavity body is arranged in the heat sink, an aluminum substrate is arranged at the bottom of the hollow cavity body, and an LED light source is arranged on the aluminum substrate, The reflector is composed of an upper reflector and a lower reflector. The upper reflector is disposed in the hollow cavity and the upper reflector is matched with the shape and size of the hollow cavity. The upper reflector and the lower reflector are both For high-reflectivity material, one-time injection molding, a diffusion plate is arranged between the upper reflector and the lower reflector, and the front frame is disposed outside the lower reflector. The reflector of the present invention is composed of an upper reflector and a lower reflector, and both are injection molded by a high reflectivity material, and the process is simple, and there is no light absorption in the area illuminated by the LED light. A diffusing plate is arranged between the upper reflector and the lower reflector, so that the light emitted by the LED light source is reflected by the upper reflector and then passed through the diffusing plate to make the emitted light very uniform without glare; after being diffused, the light is emitted. The uniform light is reflected by the lower reflector to improve the light extraction efficiency.

In order to further reduce the light loss and improve the light effect, it is preferable that the surface of the aluminum substrate is covered with a reflective paper, and the reflective paper is provided with a small hole for exposing the LED light source.

Preferably, the reflective paper is fixed to the aluminum substrate by screws.

Preferably, the upper reflector and the lower reflector are fixed by screws.

Beneficial effect

The principle and beneficial effects of the present invention adopting the above technical solutions are:

The driver and the lamp body of the utility model are of a reversible design, and the position of the driver is adjusted by the flipping member to make the driver close to or away from the lamp body, which is flexible and variable, can effectively reduce the height requirement of the ceiling of the ceiling, and create a wide suitable for the user. Living space, and when the drive is flipped away from the lamp body, the heat of the downlight does not bake the drive, protecting the normal operation of the drive; in addition, the utility model adopts a reflector with a high reflectivity material for one-time molding, Fully reduce production costs and improve product competitiveness; and place reflective paper on aluminum substrates to effectively improve light efficiency and achieve energy-saving standards.
