Abstract

The utility model provides a LED (light -emitting diode) fluorescent lamp, is equipped with the fluorescent tube, and the both ends of fluorescent tube are equipped with lamp pipe plug, and every lamp pipe plug's interior terminal surface all is equipped with LED luminous element, is equipped with the reflector of cover on LED luminous element in the fluorescent tube, and the reflector at fluorescent tube both ends sets up in opposite directions, and the internal surface of reflector is followed cup circumference and is equipped with a plurality of helicla flutes, is equipped with in the fluorescent tube between the reflector along the light pipe of the axis setting of fluorescent tube circumference along the body on the inner wall of light pipe is equipped with a plurality of arcuations arch. The utility model discloses an if the helicla flute through changing reflection of light angle, enlarges the illumination zone, the light -emitting rate has been improved to through the leaded light of light pipe, reduction LED's quantity when guaranteeing luminous effect reduces luminous heat, the length that still can lengthen the fluorescent tube, if the arcuation is protruding, increased heat radiating area, good radiating effect has, if the reflector with the light derivation at fluorescent tube both ends, is avoided because of the elongated reduction illuminating effect of fluorescent tube, reduction in production cost, the light -emitting is softer.

Description

A kind of LED daylight lamp

Technical field

This utility model relates to a kind of daylight lamp, particularly to a kind of LED daylight lamp。

Background technology

The structure of existing LED daylight lamp mainly includes fluorescent tube, along the some LED illuminator of the axial arranging of body in fluorescent tube, the light that LED illuminator sends is towards the tube wall of fluorescent tube, the light of the LED illuminator of this structure is concentrated mainly on fluorescent tube surrounding, straightline propagation principle according to light, light near the two ends of fluorescent tube is few, illuminating effect is poor, simultaneously, the quantity of LED illuminator is many, quantity of heat production is high, dispel the heat bad, make the very easily rapid increase of the temperature in fluorescent tube, the uniformity of light and differential seat angle, light-out effect is undesirable, also can have impact on life-span and the luminous efficiency of LED illuminator, simultaneously, device is many, structure is complicated, cost is high。

Summary of the invention

Technical problem to be solved in the utility model is for the deficiencies in the prior art, it is provided that a kind of reasonable in design, it is ensured that the uniformity of light and the LED daylight lamp of lighting angle。

Technical problem to be solved in the utility model is to be realized by following technical scheme, this utility model is a kind of LED daylight lamp, it is characterized in, it is provided with fluorescent tube, the two ends of fluorescent tube are provided with lighting tube plug, the inner face of each lighting tube plug is equipped with LED illuminator, the reflection shield covering in LED illuminator it is provided with in fluorescent tube, the reflection shield of lamp tube ends is oppositely arranged, the inner surface of reflection shield is circumferentially with some helicla flutes along cup, the light pipe that the axis along fluorescent tube is arranged it is provided with in fluorescent tube between reflection shield, on the inwall of described light pipe along body to be circumferentially with some arcuations protruding。

Technical problem to be solved in the utility model can also be realized further by following technical scheme, the outer surface of described reflection shield, is just equipped with heat dissipating layer in the arcuation projection of light pipe inwall。

Technical problem to be solved in the utility model can also be realized further by following technical scheme, is provided with the socket of LED illuminator on described lighting tube plug, and LED illuminator is provided with the socket coordinated with socket。

Technical problem to be solved in the utility model can also be realized further by following technical scheme, is equipped with LED drive circuit on each lighting tube plug。

Technical problem to be solved in the utility model can also be realized further by following technical scheme, and described arcuation projection is provided with three, and the circumference along light pipe is uniformly distributed。

Technical problem to be solved in the utility model can also be realized further by following technical scheme, and the length of described fluorescent tube is 80-120cm。

This utility model, by setting helicla flute, by changing reflecting angle, expands illumination zone, improve light emission rate, and by the leaded light of light pipe, while ensureing illumination effect, reduce the quantity of LED, reduce luminous heat, temperature rising in fluorescent tube is avoided to affect life-span and the luminous efficiency of LED illuminator, can the length of prolonging lamp tube, additionally aid light direct projection when reducing maintenance and cause the discomfort of maintainer eyes, if arcuation is protruding, add area of dissipation, there is good radiating effect；If reflection shield, the light of lamp tube ends is derived, it is to avoid reduce illuminating effect because fluorescent tube is elongated。Compared with prior art, it is reasonable in design, and simple in construction reduces production cost, improves uniformity and the illuminating effect of light, goes out light softer, is particularly suitable for the illumination of the fluorescent tube that length is more than 100cm。

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model。

Detailed description of the invention
