Embedded LED (light-emitting diode) bulb lamp

Abstract

The invention relates to an LED (light-emitting diode) lamp and particularly provides an embedded LED bulb lamp. The embedded LED bulb lamp structurally comprises a down lamp surface ring, a bulb is fixedly arranged below the interior of the down lamp surface ring, a circuit board is fixedly clamped above the down lamp surface ring, an LED light source is arranged below the circuit board, and a radiator and a driver are connected above the circuit board. Compared with the prior art, the embedded LED bulb lamp has the characteristics of being simple in structure, obvious in use effect and high in light efficiency and saving raw materials.

Description

technical field [0001] The invention relates to an LED lamp, in particular to an embedded LED bulb lamp. Background technique [0002] LED lamps in the prior art, especially LED lamps embedded in the ceiling, generally have the following three types: [0003] 1. Embedded downlight: It is a lighting fixture embedded in the ceiling, and its structural parts include ① downlight face ring ② reflective cup ③ downlight bracket ④ downlight base ⑤ E27 lamp holder lamp holder ⑥ reflective cup shrapnel ⑦ The shrapnel of the downlight bracket has a complex structure and wastes raw materials. It cannot be used alone. It must be equipped with a corresponding light source. The lighting principle is that the light source refracts the light through the reflective light cup, and the light is concentrated and unidirectional. Only its opposite side can receive light. And the corner layer of the beam belongs to the concentrating light, the light is concentrated, the contrast between light and ...

[0004] 2. LED downlight: It is a lighting product embedded in the ceiling lamp, and its structural parts include ① downlight face ring ② downlight bracket ③ reflector cup ④ light source part ⑤ radiator ⑥ LED light source driver ⑦ The use of flat light-transmitting covers has disadvantages, such as using reflective cups to refract light, which results in loss of light efficiency, and only the opposite surface receives light, and the light outlet is limited by the area of ​​the flat light-transmitting cover, the light receiving area is small, and the refraction angle of the reflective cups is related to the refracted light. Loss, the plane transparent cover has no effect of diffusing light, and the irradiation angle range is small

Its disadvantages: ① unidirectional light emission, only the opposite side receives light

② After the light passes through the optical lens, the light is relatively concentrated, the contrast between light and dark in the field of view is strong, and the brightness difference between the background and the center of the field of view is large, which is easy to produce glare, which can easily cause visual fatigue or directly damage the eyes. targeted local lighting
