Light source module

A light source module, in particular, a light source module composed of a plurality of pluggable light strips.

With the advancement of the times technology, the application of light-emitting diode light sources has gradually become widespread. The basic principle of illuminating diode luminescence is released in the form of light based on the combination of electron holes. The light-emitting diode can be further divided into two types: an inorganic light-emitting diode and an organic light-emitting diode. The light-emitting diode has the advantages of small volume, fast reaction speed, good focusing, long service life, low power consumption, and good shock resistance.

The application of the light-emitting diode linear light source in the backlight module has gradually matured, and the original bilateral light source design has evolved into a single-side light source design, and may even be replaced by a corner-side light source. A common light-emitting diode linear light source is formed into a strip-shaped light-emitting device. Usually, a plurality of light-emitting diode units are mounted on a strip substrate to form a linear strip light, thereby causing the light-emitting diode linear strip light to generate light. Shooting to one side provides a sufficient light source for the light guide or backlight module.

In the foregoing light-emitting diode linear strip lamp, the extended light-emitting diode line is The length of the light source of the light source, the common method is to make several light-emitting diodes are soldered on the long strip substrate by surface mount technology (SMT), so multiple soldering processes are required, resulting in an increase in process complexity. Moreover, due to the limitation of the design of the connection mode, the conventional light-emitting diode linear strip lamp is usually unable to set the light source at the corners of the panel, or an additional light guide device is required to be attached to the corner, which will incur additional cost.

The problem of uneven illumination at the corners. In addition, the light bar can be inserted and removed in a repeating extension connection, which can reduce the amount of surface adhesive welding, thereby reducing the process complexity.

The invention provides a light source module. The light source module includes two light bars and light emitting elements disposed on the light bars. The two ends of each light bar are respectively designed with a concave portion and a convex portion.

The two light bars can be vertically connected by the concave portion and the convex portion, and the concave portion and the convex portion can be electrically connected after being combined. By adopting such a combination of similar sockets, the light source module of the present invention can be applied to the side of the four corners of the light guide plate to emit light to the backlight. Furthermore, the pluggable design provides an easy assembly method that reduces the amount of surface adhesive soldering used and reduces process complexity. And this group The combination method makes the corner light more uniform, which can solve the problem that the conventional light-emitting diode backlight cannot be illuminated at the corners.
