Embodiment

[0019] Embodiment: A kind of LED lamp with uniform light distribution in this embodiment, such as figure 1 As shown, it includes the lamp cap 1, the spherical lampshade 2 and the lamp cup 3 connecting the lamp cap 1 and the spherical lampshade 2. The lamp cup 3 is clamped with the lamp cap 1 and the spherical lampshade 2 respectively. The ratio of the diameter of the spherical lampshade Φ② to the maximum diameter of the spherical lampshade Φ① is 0.9-1.5, the spherical lampshade 2 is made of PC material added with nano-scale circular diffusion particles, the mass of nano-scale circular diffusion particles accounts for 2%-3% of the total mass of PC material, and the nano-scale circular diffusion particles are evenly distributed In PC material.

[0020] The LED lamp is an A19 lamp, and the caliber of the spherical lampshade is the diameter of the connecting port used to connect the lamp cup on the spherical lampshade. The ratio of the caliber Φ② of the spherical lampshade to the...

Abstract

The invention discloses an LED lamp with uniform light distribution. The LED lamp comprises a lamp cap, a spherical lamp cover, and a lamp cup for connecting the lamp cap with the spherical lamp cover; and the ratio of the caliber of the spherical lamp cover to the maximum diameter is 0.9-1.5. Based on no change of an LED bead arrangement structure and no adding of other devices, the light distribution of the LED lamp is more uniform, and the light distribution angle is larger.

Description

technical field [0001] The invention relates to the technical field of LED lamps, in particular to an LED lamp with uniform light distribution. Background technique [0002] Based on the characteristics of LED light source such as small size, low power consumption, long service life, high brightness, and low heat, LED will be the most ideal light source to replace traditional light sources. With the maturity of LED technology, LED lamps designed with LED light sources have been widely used. North American Energy Star requirements: 1. 5% luminous flux in the range of 130-180°; 2. Light intensity value in the range of 0-130°, ≥80% of point light intensity and average light intensity ratio change ≤35%; 3. The light intensity variation of all points is ≤60% of the average light intensity. In order to meet this requirement, the general arrangement of LED lamp beads is a three-dimensional structure, such as vertically distributed LED lamp beads, or arranged in the form of corn k...
