DETAILED DESCRIPTION

[0025] The specific implementation of the embodiment of the utility model is described below with reference to the accompanying drawings.

[0026] Embodiment 1.

[0027] Reference Figure 1 and Figure 2 , an LED package shell capable of generating colored light, comprising a main shell 10, a filling block 12, and a conductor 21 installed between the main shell 10 and the filling block 12. The main shell 10 and the filling block 12 are integrally injection molded to enhance the structural tightness of the package shell. A reflective cup 11 for accommodating an LED chip 13 is provided on the upper side of the main shell 10. At least one LED chip 13 is placed in the reflective cup 11, and a plurality of color block areas 30 are installed on the side wall of the reflective cup 11. In this embodiment, the LED chip 13 is preferably a white light LED chip. When the white light emitted by the LED chip 13 after being powered on irradiates the color block area 30, since the white light is a composite light, when irradiating the color block area 30, it can reflect the light of the same color as the color block area 30. By connecting the LED chips 13 corresponding to the color block area 30 one by one, multiple colors of light can be emitted simultaneously. Since only one white light LED chip is used, the production cost is greatly reduced and the production efficiency is increased. The shape of the color block area 30 can be one of a rectangle, a circle, a diamond and any other shapes. In this embodiment, the shape of the color block area 30 is preferably a conical surface with a width equal to the depth of the reflective cup 11 and an arbitrary length, so that the light emitted by the LED chip 13 is more uniform after being reflected by the color block area 30. The electrode layer 20 includes a plurality of groups of conductors 21 and a plurality of groups of pins 22. The pins 22 include positive pins 221 and negative pins 222. The conductors 21 and the pins 22 are integrally formed. The conductors 21 are isolated from each other by an insulating layer 23. The conductors 21 extend to the bottom surface of the reflective cup 11. The conductors 21 include at least one positive electrode conductor 211 and at least one negative electrode conductor 212. Each conductor 21 is used to install an LED chip 13. The positive pins 221 and the negative pins 222 are arranged and wrapped on both sides of the main housing 10 at intervals.

[0028] More specifically, in this embodiment, three color block areas 30 are arranged on the side wall of the reflective cup 11. In this embodiment, three white light LED chips are arranged in the reflective cup 11. The conductors 21 are three groups, namely three positive conductors 211 and three negative conductors 212. The three positive conductors 211 are arranged at one side of the main shell 10 at intervals, and the three negative conductors 212 are arranged at the other side of the main shell 10 at intervals. Compared with only one white light LED chip being arranged in the reflective cup 11, which is placed at the bottom center of the reflective cup 11, it is also possible to achieve the color of the color block area 30 reflected by the emitted white light to generate light of multiple colors. However, a single LED chip 13 has the problem of insufficient light and unclear reflected color. In this embodiment, the better solution is to correspond the color block areas 30 on the side wall of the reflective cup 11 to the LED chips 13 one by one, and the number of the conductors 21 is the same as the number of the color block areas 30, and the adjacent conductors 21 are placed in a staggered manner. Through the placement of the conductors 21, the three white light LED chips are closer to the corresponding color block areas 30, and the three white light LED chips are at the same distance from the corresponding color block areas 30. When the three white light LED chips are powered on to emit white light, the light intensity of the color block areas 30 reflected by them is higher and the color is more obvious. In this embodiment, there are other situations. The LED chip 13 is other color light besides white light. If the user needs other composite color light, the color block area 30 on the side wall of the reflective cup 11 and the light emitted by the LED chip 13 are mixed to reflect other composite color light.

[0029] Refer to Figure 3 and Figure 4 The reflective cup 11 is a trumpet-shaped structure with a diameter gradually reduced from top to bottom. In this embodiment, the reflective cup 11 is preferably provided with a convex strip 31 for adjusting the reflected light. The cross-sectional shape of the convex strip 31 is arc-shaped. The convex strips 31 are arranged horizontally on the side wall of the reflective cup 11 at intervals, so that the side wall of the reflective cup 11 is wavy. The reflective cup 11 in this embodiment is a trumpet-shaped structure with a wide top and a narrow bottom. With the convex strips 31 arranged horizontally, it can guide the light of the LED chip 13, so that the light of the LED chip 13 is evenly diffused outward, and the light is softer.

[0030] Embodiment 2.

[0031] Reference Figure 5 and Figure 6The structure of this embodiment is basically the same as that of the first embodiment, and no further description is given here. The difference lies in that: a plurality of convex strips 31 for adjusting the reflected light are provided in the reflective cup 11, and the cross section of the convex strips 31 is triangular. The convex strips 31 are longitudinally arranged on the side wall of the reflective cup 11 at intervals, so that the side wall of the reflective cup 11 is sawtooth-shaped. Each color block area 30 is arranged in a V-shaped groove area between adjacent convex strips 31, or each color block area 30 covers an area composed of several convex strips 31. The reflective cup 11 in this embodiment is in a trumpet shape that is wide at the top and narrow at the bottom. When the LED chip 13 emits light, the white light is irradiated to the V-shaped groove area of ​​the adjacent convex strips 31, which can not only guide the light of the LED chip 13, but also expand the reflection surface of the light, so that the chip light is evenly diffused outward, and the softness of the light is enhanced.

[0032] Embodiment three.

[0033] Reference Figure 3 and Figure 7 The structure of this embodiment is basically the same as that of the first embodiment, and no further description is given here. The difference is that: the reflective cup 11 is provided with convex strips 31 for adjusting the reflected light, and the convex strips 31 are arranged horizontally on the side wall of the reflective cup 11 at intervals, so that the side wall of the reflective cup 11 is stepped, and each color block area 30 is respectively arranged on the vertical surface of each convex strip 31. The reflective cup 11 in this embodiment is in a trumpet shape with a wide top and a narrow bottom. With the convex strips 31 arranged horizontally, when the LED chip 13 emits white light, it irradiates the color block area 30 on the vertical surface of the convex strip 31, reflecting different color lights, thereby enhancing the softness of the LED light emission.

[0034] The above is only a specific implementation method of the utility model, but the design concept of the utility model is not limited to this. Any non-substantial changes to the utility model using this concept shall be deemed as an infringement of the protection scope of the utility model.
