Background technique

At present, most LED bulbs on the market only have illumination function, only the light emitted by the LED light source is illuminated for illumination. It is not considered whether it is decorative or not. How to make the LED bulb more beautiful and decorative is As an issue that manufacturers urgently need to solve. In the Chinese patent CN 201973493 U, an LED bulb capable of generating a backlight is disclosed, which realizes the light emitted by the LED bulb by opening a heat dissipation through hole on the body of the lamp cup and a light transmission hole formed in the heat dissipation member. Part of the light is emitted along the light transmission hole, and is radiated to the outside through the heat dissipation through hole to form a backlight. In this way, although the LED bulb is provided with a backlight for aesthetic function, the backlight is emitted through the light-transmitting hole and then through the heat-dissipating through-hole, and the light transmitted through is limited, resulting in a backlight effect is not obvious, and at the same time, the backlight The color is the same as the primary color emitted by the LED bulb, and does not have a decorative function.

In addition, the LED light bulb adopting such a single light source to realize the backlight effect has high power requirement for the LED light source, that is, the light brightness for the illumination function is lower than the required brightness under the action of the LED light source of the same power. Therefore, only a higher power LED light source can be used, and thus higher requirements are imposed on the heat dissipation and cost of the LED light bulb.
