Abstract

The utility model discloses a wide-angle LED (light emitting diode) fluorescent lamp with a uniform light effect. The wide-angle LED fluorescent lamp comprises an aluminum substrate, wherein LED light sources are fixed on the lower surface of the aluminum substrate; a lamp shell is fixed above the aluminum substrate; a driving power supply is arranged between the lamp shell and the aluminum substrate; a lampshade is fixed below the aluminum substrate; the section of the aluminum substrate is arc-shaped; the LED light sources are distributed under the aluminum substrate and on the arc-shaped surfaces on the left side and the right side of the aluminum substrate; a slight-wavy curved surface is formed on the inner wall of the lampshade; a layer of warm-color light transmittance film is plated above the curved surface. The LED fluorescent lamp with the structure disclosed by the utility model has a large illumination angle; furthermore, the wavy curved surface on the inner wall of the lampshade and the warm-color light transmittance film enable light rays to be subjected to refraction and diffuse reflection for many times, so that the illumination intensity at each angle is very uniform; the whole wide-angle LED fluorescent lamp is high in light transmittance performance and high in brightness, and the light rays are soft and are not dazzling.

Description

The uniform Wide-angle LED fluorescent lamp of a kind of light efficiency

technical field:

The utility model relates to the technical field of LED light fixture, relates in particular to a kind of LED fluorescent lamp.

background technology:

LED fluorescent lamp is compared incandescent lamp economize on electricity up to more than 80%, and it is more than 10 times that the life-span is common fluorescent tube, is almost non-maintaining, do not have the problem that will often change fluorescent tube, ballast, starter, therefore be more and more subject to affirming on market.

Existing LED fluorescent lamp is installed multiple row LED light source in order to reach the effect that irradiating angle is large on substrate, but be definite value because every row light source exists a determining deviation and the luminous irradiating angle of every LEDs, light portion that all angles are irradiated to can be superposeed causes whole light inhomogeneous, and in order to promote brightness, LED fluorescent lamp normally adopts CREE and AOD ultra-bright LED white light as illuminating source, although brightness is higher, light is soft not.

utility model content:

The purpose of this utility model is exactly in order to solve existing issue, and provides a kind of light efficiency uniform Wide-angle LED fluorescent lamp, makes the light intensity of each irradiating angle very even, and integral body not only light transmission is good, and brightness is high, and light is soft not dazzling.

Technology solution of the present utility model is as follows:

The uniform Wide-angle LED fluorescent lamp of a kind of light efficiency, it includes aluminium base, aluminium base lower surface is fixed with LED light source, aluminium base top is fixed with lamp housing, between lamp housing and aluminium base, is placed with driving power, and aluminium base below is fixed with lampshade, described aluminium base cross section is circular arc, LED light source be distributed in aluminium base under and on the arcwall face of the left and right sides, lampshade inwall forms tiny waveform curved surface, curved surface top is coated with one deck warm colour light-transmissive film.

As preferably, the LED light source angle on described aluminium base is 30 ° ~ 45 °.

As preferably, in the waveform curved surface of described lampshade inwall, the crest of each wave is identical with trough size, and the angle of adjacent two crests is 3 ° ~ 5 °.

The beneficial effects of the utility model are:

The LED fluorescent lamp lighting angle of the utility model structure is large, and the waveform curved surface of lampshade inwall and warm colour light-transmissive film make light carry out repeatedly refraction and diffuse reflection, thereby the intensity of illumination that reaches each angle is very even, integral body not only light transmission is good, brightness is high, and light is soft not dazzling.

accompanying drawing explanation:

Fig. 1 is the utility model structural section schematic diagram.

In figure: 1, aluminium base; 2, LED light source; 3, lamp housing; 4, driving power; 5, lampshade; 6, warm colour light-transmissive film; 51, crest; 52, trough; A, LED light source angle; B, crest angle.

the specific embodiment:

As shown in Figure 1, the uniform Wide-angle LED fluorescent lamp of a kind of light efficiency, it includes aluminium base 1, and aluminium base 1 lower surface is fixed with LED light source 2, and aluminium base 1 top is fixed with lamp housing 3, between lamp housing 3 and aluminium base 1, be placed with driving power 4, aluminium base 1 below is fixed with lampshade 5, and described aluminium base 1 cross section is circular arc, LED light source 2 be distributed in aluminium base 1 under and on the arcwall face of the left and right sides, lampshade 5 inwalls form tiny waveform curved surface, and curved surface top is coated with one deck warm colour light-transmissive film 6.

Particularly, the LED light source 2 angle a on described aluminium base 1 are 30 ° ~ 45 °.

Particularly, in the waveform curved surface of described lampshade 5 inwalls, the crest 51 of each wave is identical with trough 52 sizes, and the angle b of adjacent two crests 51 is 3 ° ~ 5 °.

The foregoing is only preferred embodiment of the present utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all should belong to the scope of the utility model protection.
