Light-emitting diode (LED) single-tube energy-saving lamp

Abstract

The invention relates to a light-emitting diode (LED) single-tube energy-saving lamp which comprises a lamp casing, a plastic casing, LED lamp beads, an aluminum substrate and a lamp holder, wherein the aluminum substrate is arranged in the plastic casing which is connected to the bottom of the lamp casing, and the lamp holder is fixed at the bottom of the plastic casing. The LED single-tube energy-saving lamp further comprises a conical LED light source frame, wherein the LED lamp beads are arranged on the outer surface of the LED light source frame, and the lower portion of the LED light source frame is fixed on the aluminum substrate and extends into the lamp casing. Therefore, light of the LED lamp beads is dispersed to all lateral surfaces of the lamp casing, brightness of the LED energy-saving lamp at all angles is consistent, the utilization rate of the light is fully increased, and lighting effect is good. In addition, the LED light source frame extends into the lamp casing, so that attractiveness of the LED energy-saving lamp is improved. The LED single-tube energy-saving lamp is ingenious in design, attractive in appearance, capable of effectively increasing lighting coverage area and widely applicable to lighting at public places or homes. Furthermore, compared with the energy-saving lamp with the same power as the LED single-tube energy-saving lamp, brightness is improved by more than 60%.

Description

technical field [0001] The invention relates to a lighting fixture, in particular to an LED single-tube energy-saving lamp. Background technique [0002] LED lamps are a new type of light source with long life, high luminous efficiency and significant energy saving, and they play an important role in public lighting. In the existing LED lamps, the LED lamp beads are generally pasted on the aluminum substrate, and then the aluminum substrate is installed in the plastic shell, and the transparent lamp shell is put on the outside. The LED lamp with this structure is because the LED lamp beads are facing The front end of the lamp housing basically transmits the luminance from the front end of the lamp housing, which causes the brightness of the side of the LED lamp to be darker than that in front of it, which reduces the utilization rate of the light source and seriously affects its Illumination effect and energy waste, and because the LED lamp beads are relatively concentrated...

Problems solved by technology

In the existing LED lamps, the LED lamp beads are generally pasted on the aluminum substrate, and then the aluminum substrate is installed in the plastic shell, and the transparent lamp shell is put on the outside. The LED lamp with this structure is because the LED lamp beads are facing At the front of the lamp housing, the luminance generated by it is basically transmitted from the front of the lamp housing, resulting in the brightness of the side of the LED lamp being darker than that of the front, reducing the utilization rate of the light source and seriously affecting its Illumination effect and waste of energy, and because the LED lamp beads are concentrated, the heat dissipation effect is poor, and the shape is not beautiful
