Embodiment 1

[0026] Example 1: figure 1 , figure 2 , image 3 , Figure 4 , an LED bulb lamp with adjustable color temperature, including a lamp base 1 and a bulb shell 2, and an LED light source provided in the bulb shell 2, the LED light source includes a first light source 3 and a second light source 4 that are controlled independently of each other , the first light source 3 and the second light source 4 are arranged parallel or coplanar with each other and coaxially with the lamp head 1, the first light source 3 includes a first substrate 31, and the first substrate 31 is provided with a first LED chip composed of several LED chips. The light-emitting chip group 32, the second light source 4 includes a second light-emitting chip group 41 composed of several LED chips, the surfaces of the first light-emitting chip group 32 and the second light-emitting chip group 41 are respectively wrapped with first fluorescent glue with color temperature difference Layer 33 and the second fluore...

Embodiment 2

[0029] Example 2: see Figure 5 , Figure 7 , Figure 8 , the second light source 4 includes a second substrate 43 on which the second light-emitting chip group 41 is disposed, and the second substrate 43 is disposed parallel to the first substrate 31 . The first light source and the second light source are arranged on the first substrate and the second substrate separated up and down, so that each light emitting chip group has a better heat dissipation effect, and at the same time, the first light source and the second light source form a supplementary light effect up and down, which is beneficial to improve Illumination brightness and illumination area, uniform illumination and good light spots.

[0030] See Figure 6 , Figure 7 , Figure 8 , Figure 9 The first substrate 31 is provided with a through hole 311 , and the projection area corresponding to the projection of the second substrate 43 onto the first substrate 31 is located in the through hole 311 . The two e...

Abstract

The invention relates to a color-temperature-adjustable LED bulb lamp. The color-temperature-adjustable LED bulb lamp comprises a lamp cap, a bulb shell and an LED light source arranged in the bulb shell. The LED light source comprises a first light source body and a second light source body which are independent of each other and are separately controlled. The first light source body and the second light source body are parallel to each other or coplanar and are coaxial with the lamp cap. The first light source body comprises a first substrate. A first light-emitting chip set composed of multiple LED chips is arranged on the first substrate. The second light source body comprises a second light-emitting chip set composed of multiple LED chips. The surface of the first light-emitting chip set is wrapped with a first fluorescent adhesive layer, the surface of the second light-emitting chip set is wrapped with a second fluorescent adhesive layer, and the first fluorescent adhesive layer and the second fluorescent adhesive layer are different in color temperature. The luminous flux proportion of the light emitted by the first light source body and the light emitted by the second light source body is adjusted by changing the current across the first light source body and the current across the second light source body, light with different color temperatures is obtained through mixing, and adjustment of and control over the color temperature of the light emitted by the LED bulb lamp are achieved.

Description

technical field [0001] The invention relates to an LED lighting lamp, in particular to an LED bulb lamp with adjustable color temperature. Background technique [0002] LED technology is becoming more and more mature, but most of the current LED bulbs have a single color temperature. In order to achieve the purpose of dual color temperature or adjustable color temperature, SMD packages with different color temperatures are usually used. The entire control circuit is complicated, and the light emission of SMD devices The overall light mixing effect is poor when the angle is small, which limits the use of LED lights in lighting to a certain extent. Contents of the invention [0003] The invention provides an LED bulb lamp with a 360-degree full-angle luminous effect, and can realize dynamically adjustable color temperature by mixing light sources with high and low color temperatures; it solves the problems in the prior art that the color temperature is difficult to adjust an...
