Problems solved by technology

[0008] 2. It obtains only two different light-emitting areas by pressing the switch three times, and the change range of the light-emitting area is small, which cannot well meet people's use needs
[0009] 3. If the LED light-emitting module of this lamp fails, it is difficult for people to realize the reuse of LED lamps by replacing them, which is not conducive to people's use and is not environmentally friendly.

Abstract

The invention discloses a lamp. The lamp (10) comprises a body (11) and a light-emitting device (12) which is mechanically and electrically connected with the body, the light-emitting device (12) comprises at least two light-emitting modules (121, 122, 123 and 124), at least one of the light-emitting modules (122, 123 and 124) of the at least two light-emitting modules can move between the retracting position and the unfolding position, and therefore the light-emitting device (12) has various light-emitting areas with different areas. Besides, the lamp is very compact in structure when the light-emitting device is completely retracted.

Description

technical field [0001] The invention relates to a lamp. Background technique [0002] As a new light source, LED lamps have been widely used due to their advantages of high efficiency, pure light color, low energy consumption, long life, reliability and durability, no pollution, and flexible control. [0003] Existing LED lamps (such as household desk lamps) usually have a main body and an LED lighting module. Wherein the LED light-emitting module has LEDs and a driving circuit for driving the LEDs, and the switch of the lamp is arranged on the main body. When this known LED lamp is in use, all the LEDs in the LED lighting module are turned on by turning on the switch on the body. [0004] In some specific occasions, people may not need excessively bright lighting, so it is expected that the light-emitting area of ​​the LED lamp becomes smaller, thereby reducing the brightness of the lamp. On the contrary, in some other specific occasions, people may need brighter lightin...
