LED (Light Emitting Diode) lamp

Abstract

The invention relates to the technical field of illumination, in particular to an LED (Light Emitting Diode) lamp which adopts an aluminum tube profile heat radiating piece. A heat radiating structure consists of a plastic insulating external cup and the aluminum tube profile heat radiating piece, wherein the outer side of the aluminum tube profile heat radiating piece is coated with the plastic insulating external cup; a power panel is inserted into an inner cavity of the aluminum tube profile heat radiating piece; the side wall of the inner cavity of the aluminum tube profile heat radiating piece is provided with a guidance groove; the top of the power panel is provided with a T-shaped bump or an inverse L-shaped bump; a rectangular groove of which the length is matched with the length of the top of the T-shaped bump is formed in the middle part of an LED display panel; an external PC (Polycarbonate) full optical angle reflecting cover is arranged on a PC ball head; a V-shaped reflecting surface is formed on the reflecting cover; a reflecting cup is arranged on the V-shaped reflecting surface of the external PC full optical angle reflecting cover. By the adoption of the LED lamp which enables plastic and aluminum tube profile to be combined, the cost is lowered; the heat radiating requirement is met; the insulation requirement of a safety standard is followed quite easily; a composite structure of the LED lamp is optimized; the problems about the rapid assembly of a heat radiating piece, a power source and an LED light source board are solved; moreover, a user can select various light irradiating angles according to lamp demands through the external PC cover.

Description

[technical field] [0001] The invention relates to the technical field of lighting, in particular to an LED lamp using aluminum tube profiles as heat sinks. [Background technique] [0002] With the increasing popularity of LED lamps, both large-scale outdoor displays and home lighting are inseparable from LED lamps. However, due to the high price of LED lamps, the popularity rate is affected. Usually, LED bulb lamps, candle lamps and MR16 spotlights Most of them adopt the appearance aluminum heat dissipation structure, the structure cost is high, and because the aluminum material conducts electricity, its safety performance is not good, and the production is difficult to meet the safety requirements. However, if a common plastic structure is used to dissipate heat, although the cost is reduced, the heat dissipation effect will often be poor, resulting in a reduction in the service life of the LED lamp. [0003] In the prior art, there is also a step-by-step injection molding...
