Up-down emergent LED panel lamp

Abstract

The invention provides an up-down emergent LED panel lamp. The up-down emergent LED panel lamp comprises a rectangular lamp frame, a driving power supply, an aluminum substrate and a light pervious cover. The driving power supply is fixed into the rectangular lamp frame. The light pervious cover is fixed to the surface of the rectangular lamp frame. CSP lamp beads are arranged on the lower surfaceof the aluminum substrate in an arrayed mode. The light pervious cover comprises an upper light pervious cover body and a lower light pervious cover body. The upper light pervious cover body is fixedto the upper surface of the rectangular lamp frame. The lower light pervious cover body is fixed to the lower surface of the rectangular lamp frame. The inner surface of the lower light pervious cover body is provided with a Fresnel lens. The Fresnel lens and the lower light pervious cover body are integrally designed and are fixed under the CSP lamp beads. The inner surface of the upper light pervious cover body is a smooth plane. The outer surface of the light pervious cover is a smooth plane. According to the up-down emergent LED panel lamp discloses by the invention, one part of light isemitted downwards through the Fresnel lens, and the other part of light is reflected back through the Fresnel lens and is directly emitted upwards to form up-down emergent light. The ratio of the downward emergent light to the upward emergent light is (3.5-4.5):1, and the visual comfort is improved.

Description

technical field [0001] The invention belongs to the technical field of LED lamps, and in particular relates to an LED panel lamp with up and down light emitting. Background technique [0002] At present, there are two main lighting modes of LED panel lights on the market: one is direct type, and the other is side type. Direct-down LED panel lights, usually solder LED lamp beads on a long circuit board, insert them into a rectangular frame or semicircular plastic tube, install the driving power in the rectangular frame or semicircular plastic strip, and then cover with a light-transmitting cover or Insert into a clear plastic tube. Although the direct-type LED panel light has high light output efficiency, the thickness of the lamp body is relatively thick, and most of it emits light from one side, which fails to make full use of the space of the lamp body, and cannot be used in some environments with a lot of traffic and building beautification design. If the direct-in LED ...

Problems solved by technology

[0003] What the present invention aims to solve is the technical problem of the existing double-sided light-emitting LED panel light with complex structure, high cost, and low light-emitting efficiency. The Fresnel lens emits part of the light downwards, and the other part of the light is reflected back by the Fresnel lens, and directly emerges upwards to form an up and down light
