LED floor lamp with uniform luminance

Abstract

The invention belongs to the field of illumination devices, and particularly relates to an LED floor lamp with uniform luminance. The LED floor lamp comprises a lamp holder, an electric plate and a lampshade; the lamp holder is provided with the electric plate, the electric plate is provided with light emitting diodes, and a heat conducting aluminum plate is arranged below the lamp holder and arranged on a heat dissipating body; light reflecting plates are arranged on the left side and the right side of each light emitting diode, and each light reflecting plate comprises two first light reflecting faces and two second light reflecting faces, wherein an angle between the first light reflecting faces and the horizontal direction is 20 degrees, and an angle between the second light reflectingfaces and the horizontal direction is 75 degrees; each light emitting diode comprises an LED lamp bead, a cover body, a heat dissipating fin and a resistor; each LED lamp bead comprises a wafer, an anode rod and a cathode rod; the anode rods and the cathode rods are connected with and support the wafer and provide electric current for the wafers, so that the wafers illuminate; the heat dissipating fins are located below the LED lamp beads; and the resistors are connected with the anode rods and the cathode rods in the cover bodies in series. The LED floor lamp with uniform luminance has the advantages of being good in heat dissipating effect and uniform in luminance.

Description

technical field [0001] The invention belongs to the field of lighting devices, in particular to an LED ground lamp with uniform light emission. technical background [0002] With the rapid development of social economy and the enhancement of people's awareness of energy conservation and environmental protection, the old-fashioned incandescent lamps have already left people's sight, and energy-saving LED lamps have emerged. In recent years, with the rapid development of LED technology, its luminous efficiency has doubled, and its cost has also dropped significantly. It has many advantages such as energy saving, environmental protection, and long life, and is widely used in various lighting fields. [0003] However, when LED lights are illuminated, the light is generally direct, which is likely to cause problems such as uneven illumination and limited irradiation area, which is not conducive to the outdoor application of LED lights.

Problems solved by technology

[0003] However, when LED lights are illuminated, the light is generally direct, which is easy to cause problems such as uneven illumination and limited irradiation area, which is not conducive to the outdoor application of LED lights.

LED floor lamps are usually installed in the soil and generally have poor heat dissipation, especially in hot summer. If the heat cannot be discharged in time after long-term use, it may affect the lifespan, lighting effect and reliability of LEDs.
