The background technology is as follows:

LED light sources are typically referred to as LED light beads, which typically include a support, and LED chips packaged on the support. The simplest bracket is directly formed by two metal pins, and the simplest LED light source is formed by packaging two electrodes of the LED chip with the two metal pins and then with a transparent plastic material. Of course, the LED light source with the control function may have a plurality of pins to transmit control signals to the LED chip. For example, for an LED chip with an RGB light source, it typically has four pins.

The present support for LED light source generally comprises a plastic seat (or ceramic seat), a concave accommodating cavity is formed on the plastic seat, a plurality of pins are integrally fixed on the plastic seat, and one ends of the pins extend into the accommodating cavity to form contact ends. During production, the LED chip and the control circuit element are fixed in the accommodating cavity and are connected with each pin through a lead, and finally, the transparent plastic material for encapsulation is poured into the accommodating cavity, so that encapsulation is completed, and the LED light source is formed.

The common LED light source adopts top surface luminescence, namely the accommodating cavity is arranged on the top surface of the plastic seat, and after the packaging, the light generated by the LED chip is irradiated through the packaged plastic material to form top surface luminescence. There are currently side-packaged LED light sources according to market needs. As the name implies, the accommodating cavity is arranged on the side surface of the plastic seat, so that the side surface of the plastic seat emits light after the encapsulation is finished. See the Chinese patent of the utility model of the applicant's early application, patent number 202022770240.3, patent name: a laterally packaged LED light source bracket. The technical scheme is to realize side light emission.

Due to the limitation of the manufacturing process, the current LED light source is difficult to realize light emission in two directions. The Chinese patent No. 201620879954.9 discloses a surface mounted LED bracket capable of emitting light from two sides, and the LED light source can reflect light in two directions, but the light emitting direction is limited in the forward and reverse directions on the same straight line. This limits the application scenarios of LED light sources. In some specific products or devices, it is desirable that the light source can emit light in both the vertical and horizontal directions. The current practice is only to arrange two different LED light sources, and make the light emitting directions point to different directions respectively. The problems with this approach are:

1. the mounting is complicated, the mounting is required to be carried out twice in a patch or pin mode, and two circuit boards for bearing LEDs are usually arranged, so that the cost is high and the mounting process is complicated.

In the above technical solution, the opening direction of the first accommodating cavity is different from the opening direction of the second accommodating cavity. For example, the opening direction of the first accommodating cavity is opposite to the opening direction of the second accommodating cavity. Or, a bending part is formed in the middle of the connecting terminal, so that an included angle is formed between the opening direction of the first accommodating cavity and the opening direction of the second accommodating cavity.
