Description

A New Diffuse Reflection LED Lamp

technical field

The utility model relates to the technical field of LED lamps, in particular to a novel diffuse reflection LED lamp.

Background technique

The main technical indicators to measure the light source are the light efficiency and the energy efficiency of electro-optic conversion.

Traditional light sources include incandescent lamps, energy-saving lamps, fluorescent lamps, etc., and their luminous angle is a 360-degree solid angle, and at least 50% of the light is directed to useless directions. Although in practical applications, part of the light is returned by reflection, it is still There will be a large part of the light that is not used, and the waste of electric energy is relatively large. Therefore, the light efficiency of the best incandescent lamp is about 15LM/W, and the energy efficiency of electro-optic conversion is about 3%; the best energy-saving lighting effect is about 70LM/W, and the energy efficiency of electro-optic conversion is about 15%.

For lamps made of LEDs, the light emitting angle of the lamp beads is 120 degrees, and in most cases, 100% of the light energy is used. Theoretically speaking, compared with traditional light sources, the energy consumption of LED light sources is only 50% of that of traditional light sources. Low-power lamp beads with a luminous efficiency of 100LM/W have been commercially available, and in some laboratories it has been able to achieve more than 200LM/W, and the energy efficiency of electro-optical conversion has reached more than 20%.

Therefore, compared with traditional light sources, lamps made of LEDs have advantages in terms of light efficiency, light efficiency, lifespan, environmental protection, and safety compared with traditional light sources.

However, since LED is an efficient "point" light source, it has obvious glare stimulation effect on human eyes. Some existing solutions are to "fog" it, that is, to diffuse the light by setting a translucent cover on the optical path channel, but nearly 20% of the light energy is lost during the fogging, and the energy saving effect is affected and reduced.

Utility model content

The purpose of the invention of the utility model is to provide a new type of diffuse reflection LED lamp for the above-mentioned problems, which uses the secondary diffuse reflection light surface to realize a new light distribution path, overcome the problem of LED glare stimulation, and improve the LED lamp energy-saving effect.

The technical solution adopted by the utility model is as follows: a new type of diffuse reflection LED lamp, including LED lamp bead assembly, light distribution lens, secondary diffuse reflection light surface, transparent lampshade and shell, the LED lamp bead assembly is made of aluminum substrate and LED lamp beads welded thereon, the light distribution lens is fixed on the inner wall of the bottom of the housing and the LED lamp bead assembly is sandwiched between the two, and the LED lamp bead assembly is fixedly connected with its substrate and the inner wall of the bottom of the housing, and the The light emitting surface of the LED lamp bead is parallel to the light incident surface of the light distribution lens, the secondary diffuse reflection surface is fixedly arranged in the casing and covers the light distribution lens, and the transparent lampshade is fixedly arranged at the bottom of the casing.

As a first preferred mode, the housing is circular, and correspondingly, the LED lamp bead assembly and the light distribution lens are also bent into a circle or arc shape suitable for the housing, and the secondary diffuse reflection surface is sphere.

As a second preferred mode, the housing is strip-shaped, and accordingly, the LED lamp bead assembly and the light distribution lens are also bent into a strip shape suitable for the housing and distributed on one or both sides of the long side. The secondary diffuse reflective surface is cylindrical.

In summary, due to the adoption of the above technical solution, the beneficial effect of the utility model is: the LED lamp beads are hidden, and the light is emitted to the secondary diffuse reflection surface through the light distribution lens and scattered to the target direction, avoiding direct light and eliminating Glare is irritating to human eyes.
