Problems solved by technology

Sometimes in specific occasions, the user may want to change the color of the light emitted by the lamp, but because the color of the light emitted by the traditional lamp cannot be changed, the user must purchase a new lamp, causing unnecessary waste
In addition, for manufacturers, because the flexible design of the light output color of the lamp is not enough, it is impossible to change the light output color of the lamp according to the market demand, so that the traditional lamp has a high inventory risk

Embodiment Construction

[0033] see Figure 1 to Figure 3 The lamp in one embodiment of the present invention includes a lamp cap 100 , a lampshade 300 , a lamp body 200 connected to the lamp cap 100 and the lampshade 300 at opposite ends, and a driving circuit module 40 housed in the lamp body 200 . The lamp holder 100 is used for connecting with an external power source (not shown in the figure) so that the lamp can obtain power.

[0034] The lamp body 200 includes a lamp cup 20 and an LED module 30 installed in the lamp cup 20 . The lamp cup 20 is integrally extruded from materials with good thermal conductivity, such as aluminum and copper. The light cup 20 includes a circular support portion 21 for supporting the LED module 30, an annular extension portion 23 extending upward from the periphery of the support portion 21, and a circular extension portion 23 extending downward from the periphery of the support portion 21. An inner hollow cylindrical heat dissipation portion 25 extending in a tape...

Abstract

The invention discloses an LED (light emitting diode) light fitting which comprises a light cup, an LED module and a color cap, wherein the LED module is arranged in the light cup; the color cap is connected with the light cup and covers the LED module; the light cap and the light cup are connected in a detached mode; the color of the light cap is different from the color of the light rays emitted by the LED module; and after the LED module penetrates through the light cap, the origional color of the LED module is changed.

Description

technical field [0001] The invention relates to a lamp, in particular to a light-emitting diode lamp. Background technique [0002] Since Light Emitting Diodes (LEDs) have the advantages of long life, high luminous efficiency, small size, and low pollution, they have been increasingly used as ideal light sources in recent years and widely used in various lamps. Due to the different semiconductor materials used in different light-emitting diodes, they have different light-emitting colors. For example, red light-emitting diodes, green light-emitting diodes, orange light-emitting diodes and yellow light-emitting diodes emit red, green, orange and yellow light respectively. Light. [0003] Traditional LED lamps generally include an LED light source and a colorless and transparent lampshade for covering the LED. Therefore, the light output color of the traditional lamp depends on the light emission color of the LED light source, and the light output color of the lamp cannot be ...
