Improved structure of LED lamp

Abstract

The invention discloses an improved structure of an LED lamp, which comprises a lamp body flat plate. The lamp body flat plate is internally provided with an LED light source, the upper end surface ofThe invention discloses an improved structure of an LED lamp, which comprises a lamp body flat plate. The lamp body flat plate is internally provided with an LED light source, the upper end surface ofthe light of the LED light source irradiating in the lamp body flat plate, and the flat type laminated ladder structure leads the lamp to have very thin and attractive appearance and high energy utut the light of the LED light source irradiating in the lamp body flat plate, and the flat type laminated ladder structure leads the lamp to have very thin and attractive appearance and high energy utilization ratio. Because the LED light source inclines towards the center of the light exit free surface, the invention can lead the light to be reflected in the lamp body flat plate firstly and thenilization ratio. Because the LED light source inclines towards the center of the light exit free surface, the invention can lead the light to be reflected in the lamp body flat plate firstly and thento be radiated all around, and improve the comfort of eyes.to be radiated all around, and improve the comfort of eyes. the lamp body flat plate is a light exit free surface, and the lower end surface is a light exit surface, the LED light source is arranged in the side wall of a lamp body circularly, the light exit sthe lamp body flat plate is a light exit free surface, and the lower end surface is a light exit surface, the LED light source is arranged in the side wall of a lamp body circularly, the light exit surface adopts a concave laminated staircase structure, the side wall of the lamp body is provided with an LED light source installing hole inclining towards the center of the light exit free surface,urface adopts a concave laminated staircase structure, the side wall of the lamp body is provided with an LED light source installing hole inclining towards the center of the light exit free surface,and the LED light source is arranged in the installing hole.

Description

technical field [0001] The invention relates to a lamp with a light emitting diode (LED) light source. Background technique [0002] With the continuous improvement of LED manufacturing technology, its luminous efficacy continues to rise. Up to now, the luminous efficacy of high-power white LEDs has reached 100lm / w, and the luminous efficacy of stable products is also above 90lm / w. This light effect makes it possible for LEDs to enter general lighting. One of the main tasks in the promotion of LED for general lighting is to improve the overall light efficiency of the LED lighting system, which depends on improving the efficiency of LED lamps or effective light utilization. [0003] In addition, although the LED light source has a long service life and low energy consumption, the LED is a point light source, which only emits light into the half space, resulting in two adverse effects: First, the light emitted by the light source illuminates the uneven distribution of illumin...

AI Technical Summary

Problems solved by technology

Although this structure also improves the illuminance uniformity of LED lamps to a certain extent, the light mainly depends on the reflection of the cone to diverge, and the light-emitting effect of the light-emitting surface is not effectively exerted, and the outer wall of the concave groove is an upright structure, which is not conducive to The light in the lamp body diverges to the surroundings, so its actual use effect is not ideal
