[0027] Such as Figures 1 to 5As shown in the figure, this embodiment provides a downlight that is convenient for adjusting the light color, including a lamp housing 1 and an LED light source 2. A cavity is provided inside the lamp housing 1. One side of the lamp housing 1 is an opening. The LED light source 2 is fixedly arranged inside the cavity. A circuit board 3 is arranged at the rear side position of the lamp housing 1. The LED light source 2 is electrically connected to the circuit board 3. A changeover switch 31 is arranged on the circuit board 3. The LED light source 2 is provided with an LED light source lamp bead group 21 of two light colors. The changeover switch 31 controls the turning on or off of the LED light source lamp bead group 21 of two light colors separately or jointly through the circuit board 3. The changeover switch 31 is used to switch on the LED light source lamp bead group 21 of two light colors, or both light colors can be turned on together. The changeover switch 31 has three gears. The first gear turns on the first group of light and the other group is off. The second gear turns on the other group of lights and the first group is off. The third gear can turn on both groups of lights. In this way, a downlight with three light colors can be realized, and users can switch according to their preferences for light colors, which can reduce the production cost of the factory and the stocking cost of the supplier.

[0028] As an optional embodiment, the LED light source lamp bead group 21 is of two light colors, white light and yellow light, which are the most common.

[0029] As an optional embodiment, a rear cover 4 is arranged at the rear side position of the lamp housing 1. The rear cover 4 covers the circuit board 3 to protect the circuit board and prevent it from falling off.

[0030] As an optional embodiment, a switch cover 41 is arranged on the changeover switch 31. A first through hole 401 is arranged on the rear cover 4. The switch cover 41 extends out of the rear cover 4 through the first through hole 401 from inside the rear cover 4. The switch cover 41 is on the changeover switch 31. After the rear cover is installed, the changeover switch 31 can be toggled by toggling the switch cover 41.

[0031] As an optional embodiment, during the use of the existing downlights, once the light source is damaged, the entire downlight needs to be replaced. Now a downlight with a simple light source replacement is provided. A protruding fixing strip 11 is arranged at a position close to the opening on the outer side of the lamp housing 1. An outer ring 5 is arranged on the outer side of the lamp housing 1. A convex column 51 is arranged inside the outer ring 5. The convex column 51 of the outer ring 5 is engaged and connected along the fixing strip 11. This can modularize the light source and different styles and shapes of outer rings can be used. As long as it is rotated and buckled, it can be fixed. In addition, it is also convenient to adjust the light color, and the installation and disassembly are relatively simple.

[0032] As an optional embodiment, a lamp shade 6 is covered on the opening of the lamp housing 1. The lamp shade 6 can play an anti-glare effect.

[0033] As an alternative embodiment, a plurality of heat sinks 12 are provided at the rear side of the lamp housing 1. The heat sinks 12 can accelerate heat dissipation, and the heat sinks 12 surround the rear cover 4.

[0034] As an alternative embodiment, elastic pieces are installed on the outer side of the lamp housing 1 to fix the downlight on the ceiling.

[0035] There are two implementation schemes involved in the lamp housing 1. Among them, an aluminum cup 7 is arranged in the lamp housing 1, and the LED light source 2 is arranged in the aluminum cup 7. The aluminum cup 7 absorbs the heat emitted by the LED light source to improve the heat dissipation effect. The lamp housing 1 is made of plastic material, which can also prevent the plastic from overheating and melting. Another one is that the lamp housing 1 is made of aluminum and is formed by die casting.

[0036] Existing downlights generally have only one light color. The factory produces and installs them separately according to different light colors. Dealers also purchase downlights of different light colors according to the needs of users for the convenience of users to buy. Different light colors require corresponding production of different downlights, which increases the production cost and inventory cost. Therefore, a circuit board 3 is arranged at the rear side position of the lamp housing 1. The LED light source 2 is electrically connected to the circuit board 3. A changeover switch 31 is arranged on the circuit board 3. Two groups of LED light source lamp beads 21 with two light colors are arranged on the LED light source 2. The changeover switch 31 controls the opening or closing of the two groups of LED light source lamp beads 21 with two light colors separately or jointly through the circuit board 3. The two groups of LED light source lamp beads 21 with two light colors are switched on by the changeover switch 31, or the two light colors can be switched on together. The changeover switch 31 has three gears. The first gear turns on the first group of lights and turns off the other group. The second gear turns on the other group of lights and turns off the first group. The third gear can turn on both groups of lights. In this way, a downlight with three light colors can be realized. Users can switch according to their preference for light colors, which can reduce the production cost of the factory and the stocking cost of the supplier.

[0037] The above embodiments are the preferred embodiments of the present invention, but the embodiments of the present invention are not limited thereto. Any other changes, modifications, substitutions, combinations, and simplifications made without departing from the spirit and principle of the present invention are equivalent replacement methods and are all included in the protection scope of the present invention.
