Modular high-definition LED (light emitting diode) daylight lamp

Abstract

The invention relates to a modular high-definition LED (light emitting diode) daylight lamp, which consists of a lamp carrier, a constant current power supply module, LED light sources and a PC (Polycarbonate) housing, wherein the power supply module is of an external type; the LED light sources are an integrated light source module; the light source module is composed of LED chips, metal wires, a PC circuit board, a transparent silica gel layer, a fluorescent powder layer, a connector assemblies, a transparent epoxy resin layer and a radiator; the radiator is provided with heat dissipating fins, and the bottom of the radiator is provided with a light reflection cup; the LED chips are attached at the bottom of the light reflection cup; the LED chips and the PC circuit board are electrically communicated with each other through the metal wires; the transparent silica gel layer is solidified on the chips; the fluorescent powder layer is arranged on the silica gel layer; the LED chips, the wires, the PC circuit board, the silica gel layer, the fluorescent powder layer, the connector assemblies and the radiator are solidified by the transparent epoxy resin layer to form a whole LED light source module; a plurality of LED light source modules are connected by the connector assemblies to form an integrated LED light source module, and is connected to the PC housing through connectors; and a secondary light distribution lens is arranged in front of the integrated LED light source module and at the inner side of the PC housing.

Description

technical field [0001] The invention relates to an LED fluorescent lamp, in particular to a modular high-definition LED fluorescent lamp in which a power controller, a light source and a radiator are all realized in a modular structure. Background technique [0002] Existing LED fluorescent lamps generally have a one-piece structure. The LED fluorescent lamp with an integrated structure integrates a light-emitting device, a ballast, and a radiator, and is placed in a hollow lamp tube together with a built-in power supply. Because the power supply must be placed in the lamp tube, the lamp tube cannot be made into a special shape, but can only be an ordinary semi-cylindrical shape, with some very shallow strip grooves added on the surface at most. The surface area of ​​this half cylinder is: 2πR*h / 2=πR*h. For T8 tubes, the radius is 13mm. The surface area of ​​a 1.2-meter T8 lamp tube is: π*1.3+120=490cm2. We know that the surface area of ​​an LED radiator usually requires ...
