Abstract

The invention discloses a double-bulb LED bulb lamp comprising a lamp holder, a lamp base arranged on the top of the lamp holder in a matched manner, a circuit board driving LED chips to work, a columnar base arranged on the top of the lamp base, an inner bulb arranged on the outer circle of the columnar base, and an outer bulb arranged on the outer circle of the inner bulb. The columnar base gradually shrinks upwards from the lamp base. A cooling passageway is formed in the columnar base. At least three lines of LED lamp strips are arranged on the outer circle of the columnar base at equal intervals. The corresponding LED chips are distributed on each LED lamp strip. The distance D between each LED chip and the inner bulb is larger than 0. An air outlet communicating with the cooling passageway is formed in the top end of the inner bulb. A ventilation opening opposite to the air outlet is formed in the top end of the outer bulb. The double-bulb LED bulb lamp is large in illumination angle, wide in illumination area and gentle and uniform in light ray, and conforms to the standard of the energy star for the angle of the bulb lamp. LEDs are used as the light source of the bulb lamp, and the appearance of the bulb lamp is similar to that of an incandescent lamp.

Description

technical field

[0001] The invention relates to an LED bulb lamp, in particular to an LED bulb lamp with double bulb shells. Background technique

[0002] Traditional incandescent lamps have a relatively large luminous angle, but compared with LED lamps, they have high energy consumption and short service life. Now the markets in Europe and the United States are in great need of LED bulb lamps with large angles to replace traditional incandescent lamps. The lights are similar.

[0003] LED is made of electroluminescent semiconductor material, which has excellent characteristics such as low voltage, high efficiency, good monochromaticity, strong applicability, good stability, short response time, long life, and no pollution to the environment. Widely used in lighting, decoration and other fields. An LED bulb based on LED chips has emerged as the times require. An important difference between this kind of LED bulb and traditional incandescent bulbs is that the illuminants in...
