Problems solved by technology

The structure of the existing LED floodlight driven by constant current is generally composed of a lamp body, an LED light source, a reflector, a mask, and an LED driver. The LED light source assembly and the LED driver are installed in the lamp body. When the LED driver is damaged and needs to be replaced or repaired, the lamp body needs to be disassembled to take out the LED driver, which is extremely inconvenient
The reflector cover is set on the light source, and the light emitted by the concentrated LEDs is concentrated together, and the light is distributed by a reflector, and the light output effect is not good.

Abstract

The invention discloses a constant-current driven LED projection lamp which comprises a bottom shell, a surface cover, an LED light source assembly and an LED driver, wherein the LED light source assembly is mounted in a light source mounting slot; the LED driver is mounted in a drive mounting slot; the LED driver and the LED light source assembly are independently mounted relative to each other, so that the LED driver is conveniently replaced and maintained; and a primary side feedback type LED constant-current drive circuit is arranged in the LED driver, and the circuit is simple and can output constant current. The LED light source assembly comprises an SMD light source and a light reflector; a plurality of light reflecting cups which are in one-to-one correspondence to LED chips are arranged on the light reflector; and each light reflecting cup independently distributes light for each LED chip. The constant-current driven LED projection lamp improves light outlet efficiency, so that light spots are more uniform.

Description

technical field [0001] The invention relates to an LED lighting device, in particular to a constant current driven LED floodlight. Background technique [0002] Constant current driven LED floodlights are used to irradiate the designated illuminated surface and make the illuminance on the designated illuminated surface higher than that of the surrounding environment. It has the characteristics of low power consumption, long life, and high brightness. The structure of the existing LED floodlight driven by constant current is generally composed of a lamp body, an LED light source, a reflector, a mask, and an LED driver. The LED light source assembly and the LED driver are installed in the lamp body. When the LED driver is damaged and needs to be replaced or repaired, the entire lamp body needs to be disassembled to take out the LED driver, which is extremely inconvenient. The reflector cover is arranged on the light source, and the light emitted by the LEDs that are gathered ...
