Problems solved by technology

[0002] The existing LED lamps with variable brightness adopt the method of digitally encoding the analog signal level. In some applications that do not require high-speed response, the cost of digitally encoding the analog signal level is very high, and the circuit structure Complicated. At present, the application range of LED lights is very wide, and the demand is very large. How to make LED lights meet the demand while reducing the cost and simplifying the structure is a technical problem that continues to be solved.

Abstract

The invention relates to the field of LED package, in particular to a low-brightness LED package. The low-brightness LED package comprises a substrate, a light emitting chip, a lead wire and a packageshell. The light emitting chip is fixed on the substrate. The light emitting chip and the substrate are connected by the lead wire. The bottom area of the package shell is tightly connected with thesubstrate. The light emitting chip and the lead wire are in the package shell. The package shell has a semi-circular collapse-type depression structure on the top. Compared with the prior art, the brightness of the LED can be greatly reduced by adding the semi-circular collapse-type depression structure to the top of the package shell.

Description

technical field [0001] The invention relates to the field of LED packaging, in particular to a low-brightness LED packaging. Background technique [0002] The existing LED lamps with variable brightness adopt the method of digitally encoding the analog signal level. In some applications that do not require high-speed response, the cost of digitally encoding the analog signal level is very high, and the circuit structure Complicated. At present, the application range of LED lights is very wide, and the demand is very large. How to make LED lights meet the demand while reducing the cost and simplifying the structure is a technical problem that continues to be solved. Contents of the invention [0003] The object of the present invention is to provide a low-brightness LED package to address the above-mentioned defects in the prior art. By adding a semicircular collapsed recessed structure on the top of the package, the brightness of the chip can be greatly reduced. [0004] ...
