Integrative LED lamp

Abstract

The invention provides an integrative LED lamp which is characterized by comprising a baseplate, one or more groups of LED lamp belts and a reflective element used for increasing reflective efficiency, wherein the baseplate is provided with an integrally formed lamp cup structure which comprises a cup roof opening and a cup bottom baseplate; the at least one group of LED lamp belt is mounted on the cup bottom baseplate and positioned in the lamp cup structure; a movable fixing structure is arranged on the cup wall of the lamp cup structure; the reflective element is movably inserted into the cup wall through the movable fixing structure; part of the light emitted by the at least one group of LED lamp belt is emitted out from the cup roof opening after being reflected by the reflective element, and the other part of light emitted by the at least one group of LED lamp belt is directly emitted out through the cup roof opening. The LED lamp solves the problems of light loss, weak illumination effect and the like.

Description

technical field [0001] This application and the field of lighting particularly relate to an integrated LED lamp. Background technique [0002] In the existing LED lamps, a lampshade is installed above the light-emitting surface of the chip in the aluminum substrate, and a radiator is installed on the opposite side of the chip, that is, on the other side of the aluminum substrate. When the LED chip emits light, the real effective lighting area is a part of the area directly below the light emitting direction, so the light on the side of the LED lamp is obviously wasted. However, there are still problems even if the light-transmitting flat mirror is used for corresponding improvement. For example, the light transmittance of the general light-transmitting flat mirror is often higher than 80%, but in order to weaken the glare effect of the light passing through the lampshade, a transparent A lampshade with a low light rate, such as a frosted cover with a light transmittance of ...

AI Technical Summary

Problems solved by technology

When the LED chip emits light, the real effective lighting area is a part of the area directly below the light emitting direction, so the light on the side of the LED lamp is obviously wasted

However, there are problems even if the corresponding improvements are made by using a light-transmitting flat mirror. For example, the light transmittance of a general light-transmitting flat mirror is often higher than 80%, but in order to weaken the glare effect of the light passing through the lampshade, it is necessary to use a transparent A lampshade with a low light rate, such as a frosted cover with a light transmittance of about 70%, so that a part of the light intensity can be offset by the lampshade to achieve a soft light effect

But in this way, it will cause a large light loss to the LED chip.

[0003] Then, problems such as light loss or uneven emission of light in existing LED lamps have brought a lot of inconvenience in practical applications, and have affected the research and development of LED light source usage methods.
