Description

A combination grille lamp

technical field

The utility model relates to the technical field of LED lamps interchangeable in irradiation and lighting, in particular to a combined grid lamp.

Background technique

Wall washers and track lights are lamps used in stores and exhibition halls that need to focus on products or exhibits. The advantage is that the transmission direction of the spotlights can be adjusted according to the placement of the items to achieve the clearest However, the parts of the wall washer and the track light are basically exposed, which is neither beautiful nor dustproof. Downlight is a common indoor lighting device, which is widely used in offices, auditoriums and shopping malls. Usually, downlights are embedded into ceilings or walls, so as to maintain the unity and perfection of architectural decoration. However, with the improvement of people's aesthetics, the requirements for the illumination effect of downlights are getting higher and higher, and most of the currently installed downlights cannot adjust their illumination angles, and thus cannot achieve various illumination requirements; for this reason, many places must Use wall washers or track lights for illumination.

To sum up, in order to allow the lamps to maintain the unity and perfection of architectural decoration, and at the same time adjust the lighting angle of the lamps, a lot of meaningful exploration work has been done in the industry, such as: "A Large Angle "Adjustable LED downlight", when it is in use, when the first connecting rod is pressed down, the second connecting rod will be lifted upwards, and the lamp holder will tilt downward with the downward pressure of the first connecting rod. The first connecting rod, the second connecting rod, the hinge points of the first connecting rod and the first and second connecting pieces, and the hinge points of the second connecting rod and the first and second connecting pieces are all above the ceiling cover, so that the first connecting rod The rotation of the rod around the first and second connecting pieces is not restricted by the ceiling, so the rotation angle of the first connecting rod around the first and second connecting pieces is at least 180 degrees, that is, the adjustment angle of the lamp holder is correspondingly at least More than 180 degrees, which greatly improves the adjustment angle of the lamp holder; at the same time, press down the second connecting rod that is lifted up, and the first connecting rod will be lifted up and reset with the downward pressure of the second connecting rod, that is, the double rod Although it is simple to operate, it still has the following disadvantages:

1. When the angle of the lamp holder is adjusted to a certain angle, part of the light will be gradually covered by the ceiling cover, resulting in a waste of light use;

2. The multi-link hinge is adopted. After the hinge of the connecting rod is repeatedly bent, the hinge is prone to loosening, which affects the stability of the lamp holder after the angle adjustment, and even loses the angle adjustment function of the lamp holder;

3. Due to the use of multi-link hinges, the lamp holder adjustment mechanism becomes complicated, which is not conducive to production and is not conducive to later maintenance.

In addition, when using the existing wall washer, track light and downlight, it is usually to add a whole set of lamps to increase the illuminated area, which in turn increases the cost of the user to purchase lamps, increases the space occupancy rate of the lamps, and is not beautiful.

In view of this, the applicant conducted in-depth research on the structure of the existing adjustable LED lamps and reduced the user's investment in the cost of the lamps, which resulted in this case.
