Problems solved by technology

However, there are still some defects in using LED light sources as lighting and decorative lamps. For example, the light beam of LED is relatively concentrated, the light angle is narrow, and the astigmatism of lighting is small. In particular, the light cannot reach the back of the bulb, forming dark shadows, affecting lighting and decoration

Embodiment Construction

[0029] Such as figure 1 , figure 2 and Figure 5 As shown, in the first embodiment of the LED light bulb with backlight of the present invention, it includes a lamp body 1 , a base 2 and a lamp base 3 , and the base 2 contains an LED lamp 4 . The shape of the lamp body 1 is a hemispherical surface, and its material is glass; a convex mirror 5 is arranged in the lamp body 1, and the convex mirror 5 can be realized in the following two ways: (1) when manufacturing the lamp body 1, by thickening part of the glass A convex mirror 5 is formed on the inner surface of the hemispherical surface; (2) a convex mirror 5 is pasted separately on the inner surface of the hemispherical surface. In order to improve the reflection effect of the convex mirror 5, a layer of reflective film can be coated on the convex mirror 5. Through the reflection of the LED light by the convex mirror 5, the light can be reflected to the back of the lamp, thereby increasing the illuminance at the back of t...

Abstract

The invention relates to a LED bulb having light on the back, including a lamp body, a lamp seat and a lamp head, the inner of the lamp body is provided with LED lamps, the shape of the lamp is protruding surface, inside which is partly provided with a convex mirror, or the outside is partly provided with curved surface. The convex side on the inner surface of the lamp protruding surface is coated with tapetum lucidum, which adds the reflecting effect. The invention has the following beneficial effect: through the convex mirror and the concave surface to reflect the LED light, the light can be reflected to the back of the lamp, thereby advancing the photometric brightness of the lamp back, eliminating the shadow to make the illuminating and decorative effect even better. The invention has simple structure, easy realization.

Description

technical field [0001] The invention relates to a lamp, in particular to an LED light bulb with light on the back. Background technique [0002] LED has the advantages of long life, high luminous efficiency, no radiation, impact resistance and low energy consumption. It belongs to green energy-saving and environmental protection lighting. It has been widely used in lighting and decoration fields, and governments of various countries are encouraging the development of LED technology to save energy. However, there are still some defects in using LED light sources as lighting and decorative lamps. For example, the light beam of LED is relatively concentrated, the light angle is narrow, and the astigmatism of lighting is small. In particular, the light cannot reach the back of the bulb, forming dark shadows, affecting lighting and decoration . Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an LED light bulb with li...
