Abstract

The utility model relates to a light emitting diode (LED) bracket lamp which comprises a lamp head, a lamp tube, a plastic tube, a base plate and LED light sources, wherein the lamp tube is a transparent glass tube, the plastic tube is a milk white tube, the plurality of LED light sources are sequentially arrayed on the base plate, the base plate is inserted into the plastic tube, and the plastic tube is arranged in the lamp tube. A fluorescent powder layer is coated on the inner wall of the lamp tube of the existing bracket lamp, secondary lighting of fluorescent powder is used, and accordingly human bodies are hurt and environmental protection is not achieved. The LED bracket lamp uses the plastic tube to replace the fluorescent powder layer, has the same effect of fluorescent powder secondary lighting, simultaneously does not hurt human bodies or pollute the environment and is very simple in processing technique and very low in cost, and cost performance is multiply improved.

Description

A kind of led support lamp

Technical field

The utility model relates to a kind of led support lamp, and particularly a kind of led support lamp is realized the structure of pollution-free and high transmission rate, belongs to energy-saving lamp design and manufacturing technology field.

Background technology

China's existing led support lamp profile and traditional fluorescent lamp appearance similar, principle of luminosity is then completely different, and it is installed in several led light sources on the printed circuit substrate, and substrate is installed in again in the fluorescent tube, and (LED) is luminous by light emitting diode.Because LED has luminous intensity height, remarkable advantage that efficiency is low, thereby is widely used in recent years.According to the luminous characteristics of LED, its light that sends is blue light, and has poly-neutrality, and for general illumination, people more need well-illuminated good, the even soft white light source of light of light.Therefore existing led support lamp is inserted in a glass tube in the periphery of led light source, be coated with on the wall of glass tube into certain thickness fluorescent material, the blue light part that led light source sends is absorbed by fluorescent material, the yellow light mix that another part blue light and fluorescent material send obtains the white light that the fluorescent material secondary sends thus.This have its drawback by the luminous led support lamp of fluorescent material secondary: 1, fluorescent material contains a large amount of lead, and is plumbous very big to the influence of human body, therefore very big to direct labor's health harmfulness when making fluorescent tube; Moreover, after scrapping, fluorescent tube needs particular procedure, otherwise contaminated environment; 2, complex process, spillage of material are big, and that equipment drops into is many, labour cost is high, cost performance is low, is unfavorable for the popularization and application of LED lamp.

Summary of the invention

In order to eliminate by the luminous led support lamp of fluorescent material secondary to the harm of human body with to the pollution of environment, improve the cost performance of led support lamp simultaneously, the utility model provides a kind of pollution-free, low-cost, high transmission rate led support lamp.

The utility model Bian gets following technical scheme and implements: a kind of pollution-free, low-cost, high transmission rate led support lamp, comprise lamp holder, fluorescent tube, plastic tube, substrate, led light source, spring leaf, and described lamp holder is provided with louvre; Described fluorescent tube is glass tube, and its two ends are bonding with two lamp holders respectively; Described plastic tube external diameter is less than the fluorescent tube internal diameter; Described substrate is strip; Described led light source is a plurality of, and it is equidistant being arranged on the substrate successively, it is characterized in that:

Described glass tube is transparent pipe;

Described plastic tube is milky white colour tube;

Described plastic tube is arranged on fluorescent tube inside and paste mutually with the inner of lamp holder at two ends.

Be provided with spring leaf between one side clearance of described plastic tube external diameter and lamp holder internal diameter;

The inwall of described plastic tube is provided with one along the draw-in groove on the pipe range direction;

Described substrate is inserted in the draw-in groove that the plastic tube inwall is provided with, and makes led light source be positioned at direction outwardly;

Described spring leaf is positioned at the caliber portion in the plastic tube inwall draw-in groove outside.

The utility model arranges the milky plastic tube in the inside of Frame lamp clear glass fluorescent tube, and the flexible fixed plastics pipe of the elastic force that utilizes spring leaf circumferential position, utilize the strain location substrate of plastic tube draw-in groove buckle, make some led light sources luminous and irradiated milk white plastic tube wall on the fixed position on the substrate, make the plastic tube secondary luminous.

Useful contribution of the present utility model is: utilize plastic tube to substitute phosphor powder layer, not only can obtain the luminous effect same of fluorescent material secondary, and do not injure that human body, environmentally safe, processing technology are quite simple, cost is very cheap, cost performance rises at double.

Description of drawings

Fig. 1 looks for master of the present utility model, the broken section structural representation;

Fig. 2 is A-A cross section sectional structure schematic diagram among Fig. 1.

In Fig. 1, Fig. 2: 1 lamp holder, 2 fluorescent tubes, 3 plastic tubes, 301 draw-in grooves, 4 substrates, 5LED light source, 6 spring leafs.

The specific embodiment

As shown in Figure 1, 2, lamp holder 1 is provided with louvre; Fluorescent tube 2 is the clear glass fluorescent tube, and the two ends of fluorescent tube 2 are bonding with two lamp holders 1 respectively; Plastic tube 3 is milky white colour tube, it is arranged on the inside of fluorescent tube 2, and paste mutually with the inner of lamp holder 1 at two ends, is provided with spring leaf 6 between a side clearance of the external diameter of plastic tube 3 and lamp holder 1 internal diameter, is provided with one along the draw-in groove 301 on the pipe range direction at the inwall of plastic tube 3; Substrate 4 is strip; Led light source 5 is a plurality of, and it is equidistant being arranged on the substrate successively; Substrate 4 is inserted in the draw-in groove 301 that plastic tube 3 inwalls are provided with, and makes led light source be positioned at direction outwardly; Spring leaf 6 is positioned at the caliber portion in plastic tube 3 inwall draw-in grooves 301 outsides.

The utility model arranges milky plastic tube 3 in the inside of Frame lamp clear glass fluorescent tube 2, and the circumferential position of the flexible fixed plastics pipe 3 of the elastic force that utilizes spring leaf 6, utilize the strain location substrate 4 of plastic tube 3 draw-in grooves 301 buckles, make on the substrate 4 tube wall of some led light sources 5 luminous and irradiated milk white plastic pipe 3 on the fixed position, make plastic tube 3 secondaries luminous.The utility model utilizes plastic tube 3 to substitute phosphor powder layers, not only can obtain the luminous effect same of fluorescent material secondary, and does not injure that human body, environmentally safe, processing technology are quite simple, cost is very cheap, and cost performance rises at double.
