Abstract

An LED support frame and an LED light-emitting unit. The LED support frame comprises a base (1) and a pin (2) provided on the base (1). An accommodating cavity (11) used for accommodating an LED chip is provided on the base (1). An opening (111) is provided at a side of the accommodating cavity (11) for placement of the LED chip. One extremity of the pin (2) is arranged at a bottom part (112) of the accommodating cavity (11); the other extremity runs through the base (1) then extends from the base (1) to form an extension part (21). The extension part (21) is bent to a certain distance in the direction from the bottom part (112) to the opening (111). The accommodating cavity (11) is deeper than a common accommodating cavity. The shape and structure of the LED support frame are identical or similar to the shape and structure of a common LED support frame having a shallow accommodating cavity. This facilitates a user to use directly the improved LED support frame, which provides great versatility, and obviates the need for an additional circuit board to be provided separately, thus reducing use costs for the user.

Description

LED bracket and LED lighting unit

Technical field

Background technique

A commonly used LED holder structure for illumination or backlight display includes a pedestal and a pin extending from the pedestal, the pin being used to lead the electrode of the LED chip. The base has a rectangular outline, and an upper portion is provided with a cavity for placing the LED chip, and the base includes two sides in the longitudinal direction and two sides in the width direction (also referred to as a soldering surface), and the pins are self-contained. After the side of the base protrudes, it is bent upward and then bent and extended to the side closer to the side, so that the free end of the pin is tightly wrapped on the side, and the portion of the pin extending from the base is closely attached to the base. seat.

The cavity of the most commonly used LED bracket for placing the LED chip is shallow, and now many researchers are considering increasing the depth of the cavity to protect the LED chip. In the commonly adopted scheme, the cavity is more The general cavity is deep, so the LED chip can be protected. However, when a deep cavity is used, the pin placed at the bottom of the cavity also moves downward, causing the pin to extend beyond the base (on the same plane as the bottom of the cavity). The downward movement of the position is a large distance, resulting in a large difference in the outer shape of the LED bracket and the shape of the commonly used bracket, so that the downstream customer cannot directly use the improved LED bracket, and needs to be redesigned and adapted to the improved LED bracket. The circuit board greatly increases the user's use cost, and also brings great inconvenience to the user.
