Solar spectrum type LED (Light-Emitting Diode) eye protection panel lamp/panel desk lamp

Abstract

The invention discloses a solar spectrum type LED (Light-Emitting Diode) eye protection panel lamp / panel desk lamp. The solar spectrum type LED eye protection panel lamp / panel desk lamp comprises a front diffusion panel 1, a front grating panel 2, a circuit board 7, a rear reflection diffusion panel 5, an LED lamp bead group 6 and a ring-shaped reflector 4; the front grating panel is clung to the front diffusion panel and is arranged on a concave disk at one side of emergent light of the LED eye protection panel lamp / panel desk lamp and the front diffusion panel is arranged in the front of the front grating panel; the rear reflection diffusion panel is clung to the circuit board and is arranged on a back concave disk of the LED eye protection panel lamp / panel desk lamp and the reflection diffusion panel is arranged in the front of the circuit board; a certain distance is reserved between the front grating panel and the reflection diffusion panel so as to form a gap; the LED lamp bead group is arranged around the circuit board; LED lamp beads are positioned in the gap; and the ring-shaped reflector is arranged outside the periphery of the concave disk of the LED eye protection panel lamp / panel desk lamp. The solar spectrum type LED eye protection panel lamp / panel desk lamp does not require a light guide plate, an aluminum substrate and radiating fins and has the advantages of simple structure, low cost, greenness, environmental protection, emission spectrum which is close to a solar visible spectrum, color rendering index which is close to 100 and the like.

Description

technical field [0001] The invention belongs to the technical field of indoor lighting, and in particular relates to a solar spectrum type LED eye-protecting panel lamp / table lamp. Background technique [0002] In recent years, the tube-type and bulb-type LED lamps used for indoor lighting are either due to high directivity and glare, or due to the dense arrangement of LED lamp beads, difficulty in heat dissipation, or due to the problems of heavy heat sink and high design cost. However, it restricts its market competitiveness and is difficult to be widely used. Although LED flat panel lighting based on liquid crystal (LCD) backlight technology has basically solved the problems of high directivity and glare, it still cannot meet the requirements of color rendering index, light output efficiency and manufacturing cost, especially for reading desk lamps with vision protection. The color rendering index is even more difficult to meet or approach the requirements of standard li...

Problems solved by technology

[0005] The purpose of the present invention is to provide a spectrum complementary solar spectrum type LED eye-protecting flat panel lamp / flat desk lamp, which is different from the existing light guide plate type white LED flat panel lamp. Eliminates the shortcomings of traditional white LED lighting fixtures, such as large spectral defects and low color rendering index

In addition, the present invention adopts a design without a light guide plate, which solves the problems of low light extraction efficiency and high manufacturing cost of the whole lamp in the prior art.
