Embodiment 1

[0043] Such as Figure 1~3 As shown, a method for realizing a novel structure LED omnidirectional bulb lamp includes the following steps:

[0044] (1), Mie scattering: When the natural light incident on the scatterer particles is close to the scatterer particle linearity, the scattering effect of the isotropic spherical scatterer particles on the light wave is obtained by Mie scattering theory;

[0045] (2) The target light distribution of the bulb is established: from 0° to 135°, the point where the light intensity is more than 90% cannot deviate from the average value by 25%, the rest cannot be lower than 50%, and the luminous flux from 135°-180° cannot be <5% , as the goal of bulb light distribution design;

[0046] (3) Light source setting: the LED light source is 2mm away from the bulb and arranged in a ring on the LED substrate;

[0047] (4), 3D model establishment: use the equation F (X, Y) = 0 to establish a free curve, and convert it into a bulb model through the en...

Embodiment 2

[0062] This embodiment differs from Embodiment 1 in that: the LED lamp beads in this embodiment are 10 mm away from the bulb; the LED lamp beads are arranged in a circle, and the distance between adjacent LED lamp beads is 20 mm; The radius of the particles is 5um.

Abstract

The invention discloses a novel structure LED all-direction bulb lamp. The novel structure LED all-direction bulb lamp comprises a shell. The bottom of the shell is connected with a lamp holder. A heat dissipation piece is embedded in the shell. A PCB is arranged in the heat dissipation piece. An LED substrate comprises an LED chip. The negative electrode and the positive electrode of the LED substrate are connected to the PCB through solder paste via reflow soldering. A plurality of LED lamp beads are distributed on the circumference of the LED substrate. A bulb shell is arranged outside the LED substrate and made of PC, and the bulb shell is evenly filled with a dispersing agent. The dispersing agent is a kind of scattering particles, and the scattering particles are isotropous homogeneous small balls with the diameter of about 2 microns-10 microns. The invention further discloses an achieving method of the novel structure LED all-direction bulb lamp. The novel structure LED all-direction bulb lamp has the beneficial effects that the structure is simple, the manufacturing cost is low, and the production efficiency is high; and the labor intensity is low, the light transmittance is high, energy is saved, and the American Energy Star Standard is met.

Description

technical field [0001] The invention relates to LED lamp technology, in particular to a novel structural LED omnidirectional bulb lamp and a realization method thereof. Background technique [0002] With the development of society, LED energy-saving and environment-friendly light sources are widely used today, and various lamp manufacturers in the market are also developing faster and faster, and the shapes of lamps are different. [0003] Traditional incandescent lamps have been gradually replaced by LED omnidirectional bulbs. The appearance of LED omnidirectional bulbs is similar to that of traditional incandescent lamps, including LED light sources composed of drive power boxes and multiple light-emitting diodes. The drive power drives the light-emitting diodes to emit light. illumination. [0004] However, LED omnidirectional bulbs in the prior art have the following technical problems: [0005] (1), complex structure, difficult assembly, low production efficiency and ...
