Abstract

The invention discloses a double-layer diffuse reflection LED (light-emitting diode) fluorescent lamp, which comprises a lamp tube. Both ends of the lamp tube are respectively provided with a lamp holder; an LED illuminant is arranged in the lamp tube; the tube consists of an outer tube and a lining which are parallel; the lining is in a groove shape; two groove sides of the lining are respectively connected with the inner wall of the outer tube to form bayonets; the LED illuminant is arranged between the bayonets; the luminous surface of the LED illuminant faces the lining; and the outer tube and the lining are respectively made of glass. According to the double-layer diffuse reflection LED fluorescent lamp disclosed by the invention, as the lamp tube is made of the glass, the brightness of the lamp is higher; the temperature in the lamp tube is greatly reduced, and thus, not only is the service life of the lamp effectively prolonged but also energy sources are saved and the irradiating angle of the lamp is widened. By respectively arranging a frosted layer and a diffusion powder or fluorescent powder coating on the outer tube and the lining, the defect that glare is generated by the LED lamp is solved by the frosted layer, so that light emitted by the lamp is softer and more uniform, and the diffusion powder or fluorescent powder coating is capable of converting ultraviolet rays leaking from the LED lamp into visible light.

Description

technical field [0001] The invention relates to the field of LED lamps, in particular to a double-layer diffuse reflection LED fluorescent lamp. Background technique [0002] LED fluorescent lamp is an environmentally friendly and energy-saving lamp with higher brightness than traditional fluorescent lamps and much lower power than traditional fluorescent lamps. The lamp tube of the existing LED fluorescent lamp is composed of a PC transparent cover and an aluminum heat sink, and the LED lamp beads are arranged in the lamp tube. Due to the low light transmittance and thermal conductivity of the PC material, the LED lamp beads in the lamp tube with this structure emit light. A large part of the light stays in the lamp tube, causing the brightness of the lamp to not be maximized. At the same time, the internal temperature of the lamp tube is high, and the heat must be dissipated through the aluminum heat sink. When the lamp is in continuous operation, the temperature of the al...
