Energy-saving light-emitting diode (LED) panel lamp

Abstract

The invention discloses an energy-saving light-emitting diode (LED) panel lamp, which comprises an aluminum frame, a diffusion plate, a light guide plate, a reflecting film, an aluminum back panel, LED lamp beads and aluminum-based circuit boards, wherein the LED lamp beads are welded on the aluminum-based circuit boards and are inserted into grooves of the aluminum frame; the aluminum frame has the length of 1,500 to 1,800mm and the width of 610 to 690mm; a plurality of radiating ribs are arranged on the outer side of the aluminum frame; the upper end face of the aluminum frame is provided with dovetail grooves; the dovetail grooves are provided with conical screws; the reflecting film covers the reflecting surface of the light guide plate; double-faced adhesive tapes are adhered to the peripheries of the diffusion plate, the light guide plate and the aluminum back panel; every two of the diffusion plate, the light guide plate and the aluminum back panel are sequentially connected to form a whole; and the diffusion plate, the light guide plate and the aluminum back panel are integrally arranged in the groove of the aluminum frame. The energy-saving LED panel lamp is large in luminous area and low in power, achieves an enough and proper illumination effect, has the function of saving energy and suitable for energy-saving illumination in special small spaces such as elevators and toilets; and moreover, the energy-saving LED panel lamp is good in radiating effect, low in fault rate and convenient to mount, and the service life of the LED is prolonged.

Description

technical field [0001] The invention relates to a lighting fixture, in particular to an energy-saving LED panel lamp. Background technique [0002] Existing LED panel lamps are not large in size, the normal size is 300*300mm, the largest is 1200*600, and the power of the current 600*600mm panel lamps is generally above 40W. Therefore, the existing conventional panel lamps have the disadvantages of small light-emitting area and high power. This kind of panel light is not suitable for the narrow and special space of the elevator car. The LED panel light required for this space is large in size and low in power, especially the hospital elevator car, which is a long and narrow space. Sufficient and suitable lighting requires LED panel lights with low power and energy saving. Contents of the invention [0003] Purpose of the invention: The purpose of the invention is to provide an energy-saving LED panel light with large light-emitting area and low power in order to make up f...

Therefore, the existing conventional panel lamps have the disadvantages of small light-emitting area and high power

This kind of panel light is not suitable for the narrow and special space of the elevator car. The LED panel light required for this space is large in size and low in power, especially the hospital elevator car, which is a long and narrow space. Sufficient and suitable lighting, but also require low power and energy-saving LED panel lights
