A led lighting fixture

Abstract

The invention discloses an LED lighting fixture, which comprises a heat sink, a reflection cup, an LED module, a supporting member, a heat pipe and a vapor chamber, wherein the heat sink is provided with a center hole section and radiating sections; a concave opening is formed at the front end by the surrounding of the radiating section; the reflection cup is arranged at the concave opening; the outside of the reflection cup is surrounded by the heat pipe and makes contact with the radiating section; the LED module is arranged at the bottom of the reflection cup; the supporting member makes contact with the LED module and is arranged at the tail end of the heat pipe; and the vapor chamber is provided with a smoothing section for receiving the LED module and interposing sections for being interposed into the center hole section of the heat sink.

Description

technical field

[0001] The invention relates to a lamp, in particular to an LED lighting lamp. Background technique

[0002] Existing LED lighting fixtures, such as downlights or projection lights, in order to improve their own lighting effects, will add a reflector cup at the front, which can effectively improve the irradiation area and irradiation distance of the light source, and the deployment control is also more convenient. Based on the characteristics of high heat when LEDs are working, the lamps will be targeted to install LED cooling devices at the rear. Generally, the heat dissipation performance of the heat sink is related to its structure and heat dissipation area. At present, the most commonly used is fin type or similar structure. The greater the power of the LED, the larger the volume of the corresponding heat sink. If the corresponding parts are removed, the lamps will appear bloated, which may cause difficulties in assembly and application; in addition, for...
