LED light protection lamp with built-in driver

Abstract

The invention discloses an LED light protection lamp with a built-in driver. The LED light protection lamp with the built-in driver comprises a bottom shell, a face cover, an LED light source assembly and the LED driver; the LED light source assembly is installed in a light source installing groove; the LED driver is installed in a driver installing groove; the LED driver and the LED light source assembly are independently installed, and replacing and maintaining of the LED driver are facilitated; a non-polar thin-film capacitor C2 quite small in capacity is adopted for a driving circuit in the LED driver to replace an electrolytic capacitor, the thin-film capacitor C2 is the same as the electrolytic capacitor in filtering effect, the thin-film capacitor C2 is good in stability, extremely high in anti-interference capacity and high in reliability, and the service life of a power source is greatly prolonged. The LED light source assembly comprises an SMD light source and a light reflecting piece which is provided with a plurality of light reflecting cups corresponding to LED chips one to one; and each light reflecting cup performs independent light distribution for each LED chip, the light outgoing efficiency is improved, and light spots are made more uniform.

Description

technical field [0001] The invention relates to an LED lighting device, in particular to a driving built-in LED floodlight. Background technique [0002] The built-in LED floodlight in the driver is used to irradiate the designated illuminated surface and make the illumination 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 with built-in driver 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 driver is damaged and needs to be replaced or repaired, the lamp body needs to be disassembled as a whole 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 together is...

The structure of the existing LED floodlight with built-in driver 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 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.
