Description

Mounting assembly, lighting system and method for fixing mounting strip

Technical Field

The application relates to a mounting assembly, especially relates to a mounting assembly who is applied to illumination field.

Background

Large frame signs, which may also be referred to as box signs, use fluorescent and incandescent lamps as lighting systems. The framed sign comprises a housing with a translucent panel defining a hollow space in which fluorescent and incandescent lamps may be mounted. Fluorescent lamps are more efficient than incandescent lamps. Fluorescent tubes emit light in a 360 degree pattern from a central axis, but the light emitted from the top and bottom of the tube is typically wasted and does not reflect well to the translucent panel.

Recently, the use of more efficient lighting, particularly Light Emitting Diodes (LEDs), has become a trend. LEDs consume less power, are more reliable, and have a longer life than fluorescent lamps. Typically, bars and rails are used to support the LED-mounted lighting modules, but longitudinal bars and rails are difficult to transport and difficult to install into box signs quickly and reliably.

Accordingly, it is desirable to provide a mounting assembly that addresses at least one of the problems described above.

Fig. 8 is a front view of the first holder 100 shown in fig. 7. Fig. 9 is a cross-sectional view of the first holder 100 shown in fig. 1 taken along the line B-B. A method 301 of using a clamp, exemplified by a first clamp 100 and a second clamp 200, to secure a mounting strap 300 is shown in more detail below in connection with fig. 4-9.

Method 301 includes steps 302,304, and 306. In step 302, the slidable fastener 120 is placed in the first position 142, the first position 142 being located near the first ends 141 (shown in fig. 6) of the first and second legs 111,112 distal from the support module 113. In some embodiments, the slideable fastener 120 at the first position 142 is adjacent the base plate 114 of the stand 110, and the base plate 114 may prevent the slideable fastener 120 from sliding out of the first and

second legs

111, 112.

In step 304, as shown in fig. 6, the first longitudinal end 310 of the mounting strap 300 is folded around the support modules 113 of the rack 110 to form a first folded portion 311 of the mounting strap 300.

In step 306, as shown in fig. 7-9, the slideable fastener 120 is moved along the first and second legs 111,112 to a second position 149, the second position 149 being located near the second ends 148 (shown in fig. 9) of the first and second legs 111,112 proximate the support module 113.
