LED support and LED

Abstract

The invention provides an LED support and an LED. The LED support comprises a substrate and a base which is moulded through a die. The substrate and the base are molded into one piece. A chip unit is packaged on the substrate and is arranged inside the base. The inner wall of the base is provided with a reflection surface for reflecting light rays emitted from the chip unit. The reflection surface is moulded through a die. The substrate is provided with a heat dissipation layer for dissipating the heat from the chip unit. By smoothing and polishing the die for base moulding, the inner wall of the base is allowed to reach a smooth mirror surface effect, so that the light rays emitted from the chip unit can be reflected favorably, the light transmittance of the light rays emitted from the chip unit can be kept for a long time, and the advantages of large light-emitting area and angle are achieved; adding heat-dissipation aluminum sheets or fans to the substrate is avoided, and heat is dissipated through a heat dissipation layer in a thermal transmission manner; the heat dissipation effect is good; the service life of the LED is prolonged; the cost of the heat-dissipation aluminum sheets or the fans is saved on the premise of saving space utilization rate; and a simplification effect is achieved.

Description

technical field [0001] The invention relates to LED technology, in particular to an LED bracket and an LED. Background technique [0002] The LED bracket is used to package the LED chip unit. This LED bracket is mainly for the chip unit with a power below 0.5W. At least 20 lamp beads need to be packaged in a single row. The chip emits light, which is used to reflect the light emitted by the chip. , with the passage of time, the light transmittance will gradually decrease, making the LED darker and darker; and the chip will generate a lot of heat at the same time, and now the LED bracket products tend to be smaller and smaller, in this case Under the traditional LED bracket, heat dissipation aluminum sheets or fans are installed on the bracket body to dissipate the heat energy generated by the chip unit to the surrounding air; and in order to be able to install more lamp beads and heat dissipation aluminum sheets or fans , will inevitably make the design of the LED bracket s...
