The present invention relates to a length-variable LED lamp capable of being installed in various sized reflectors by arbitrarily extending and contracting the length. An existing LED lamp was not economical since the existing LED lamp should be separately manufactured to have a size according to the size and shape of the reflectors. To solve the problem, the present invention provides the length-variable LED lamp comprising a heat sink having a vertical guide part, mounting grooves formed on the inner surface of the guide part, and an LED module with multiple LEDs coupled to the lower part; a leaf spring coupled to the mounting grooves, and extended upward to make the end of fixing parts formed to have elastic force protrude from the mounting grooves; and a housing having a guide inserted in the guide part to be vertically movable, and multiple hanging protrusions vertically formed on the outer surface of the guide and fixed by the fixing parts. Thus, the present invention can be conveniently installed in the various sized and shaped reflectors by making a user arbitrarily adjust the length since the guide having the multiple hanging protrusions is installed to be vertically movable along the guide part. Also, the present invention can be conveniently manipulated by having simple parts and can be more economical without a concern about malfunctions. |
