Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

It will be understood that when an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. When a component is referred to as being "disposed on" another component, it can be directly on the other component or intervening components may also be present.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the description of the present application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

An embodiment of the application provides a straight LED tube lamp 1 with an improved light emitting angle, as shown in fig. 1 to 3, the straight LED tube lamp 1 includes a lamp housing 10 composed of a lamp tube 12 and lamp caps 11 disposed at two ends of the lamp tube 12, an LED light bar 13 is disposed inside the lamp housing 10, the LED light bar 13 includes a substrate 14 extending along a first direction and a plurality of LED light beads 15 arranged along the first direction, the LED light beads 15 are arranged at intervals, the specific number of the LED light beads can be set according to actual conditions, a plurality of pairs of pads 16 for fixing the LED light beads 15 are disposed on the substrate 14, each pair of pads 16 includes a first pad 161 and a second pad 162, the first pad 161 and the second pad 162 are arranged along a second direction, and the first direction and the second direction are perpendicular to each other.

For convenience of understanding, as shown in fig. 3 to 4, the X direction is a first direction, and the Y direction is a second direction. Generally, the existing straight tube lamp adopts the rectangular LED lamp beads 15, that is, the LED lamp beads 15 have the opposite long sides and short sides, each pair of pads 16 of the lamp strip 18 in the prior art are arranged along the first direction (that is, the first pad 161 and the second pad 162 are arranged along the first direction), after the LED lamp beads 15 are installed, the long sides are arranged along the X direction, and the short sides are arranged along the Y direction, during specific lighting, because the LED lamp beads 15 have a certain light-emitting angle, and the light-emitting angle of the lamp tube 12 is determined by the length of the LED lamp beads 15 in the second direction, the longer the width of the LED lamp beads 15 in the second direction is, the larger the light-emitting area of the lamp tube 12 is, and the larger the light-emitting angle of the whole lamp tube 12 is.
