Abstract
The utility model discloses a light-emitting diode (LED) lamp, which comprises a lamp tube and an LED lamp strip arranged in the lamp tube. The lamp tube comprises a light condensing structure and a light reflecting structure which are integrally formed. The light condensing structure transmits and converges light, and the light reflecting structure reflects the light. The LED lamp improves illumination of an LED lamp tube by adopting light focusing effects and greatly improves middle brightness in a freezing lighting environment and overall evenness.
Description
Technical field
The utility model relates to lighting, relates in particular to the high LED lamp of a kind of illumination brightness uniformity.
Background technology
Traditional incandescent lamp is that the filament energising is heated to incandescent state, utilizes heat radiation to send the electric light source of visible light.Shortcomings such as conventional incandescent is owing to big energy-consuming, and heat dissipation capacity is big, and the life-span is short are substituted by the LED lamp gradually, and being widely used of LED lamp become a kind of trend gradually.
The LED light emitting diode is a kind of solid-state semiconductor devices, can directly be converted into light to electricity.The LED light emitting diode has plurality of advantages such as energy consumption is low, pollution-free, radiationless, volume is little, brightness is high, the life-span is long, belong to by universally acknowledged environmental protection light source, national governments all encourage growth LED technology with energy savings.
In traditional freezing illumination, for example refrigerator throws light on, and exists the homogeneity question of irradiation brightness.Though traditional fluorescent tube angle is big, can cause the refrigerator intermediate luminance not enough, and both sides brightness is higher, causes whole lack of homogeneity.
The utility model content
The utility model has overcome deficiency of the prior art, provides a kind of illumination brightness uniformity high LED lamp.
In order to realize above-mentioned purpose, adopt following technical scheme:
A kind of LED lamp comprises the LED lamp bar that fluorescent tube is inner with being arranged on fluorescent tube, and said fluorescent tube comprises integrated concentration structure and reflective structure, and the concentration structure transmission is also converged light, the reflective structure reflection ray.This structure can promote the illumination of LED lamp, changes irradiating angle again, promotes the refrigerator intermediate luminance greatly, the whole illumination uniformity around improving simultaneously.
In the such scheme, said concentration structure adopts transparent organic glass, and said reflective structure adopts white pmma.The lucite co-extrusion of two kinds of materials is integrally formed the fluorescent tube of moulding, and transparent organic glass is extruded into concentration structure, and white pmma is extruded into reflective structure.Said concentration structure is the convex lens structure to outer lug, the convex lens structure that transparent organic glass forms, and transmitted light can converge light again well, improves brightness.
In the such scheme, be provided with the screens that installs and fixes LED lamp bar in the said reflective structure, said reflective structure outer surface is provided with heat-dissipating casing.LED lamp bar is installed in the screens, and the heat of generation is transmitted to heat-dissipating casing through reflective structure, dispels the heat effectively.
In the such scheme, said lamp tube ends adopts sealant sealing to irritate, and improves the sealing of fluorescent tube, further strengthens moistureproof effect.
Compared with prior art, the utility model adopts spotlight effect to promote the illumination of LED fluorescent tube, promotes freezing lighting environment intermediate luminance and whole uniformity greatly.
Description of drawings
Fig. 1 is the overall structure sketch map of the utility model;
Fig. 2 is the side sectional view of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done further to describe.
The overall structure of the utility model is as shown in Figure 1, and the side is as shown in Figure 2, comprises fluorescent tube 1 and LED lamp bar 2.Fluorescent tube 1 comprises integrated concentration structure 11 and reflective structure 12, and concentration structure 11 adopts transparent organic glass, and reflective structure 12 adopts white pmma, two kinds of lucite coextrusion molds.Reflective structure 12 set inside have screens, are used to install LED lamp bar 2.Fluorescent tube 1 is outside equipped with heat-dissipating casing 3 and helps heat radiation.
LED lamp when work, 2 energisings of LED lamp bar, the light that sends to around disperse.The light that shines concentration structure 11 forms the light that converges through converging; The light that shines reflective structure 12 is through penetrate from concentration structure 11 after reflective again.
Heat-dissipating casing 3 adopts the material of perfect heat-dissipatings such as aluminium alloys to process, and is enclosed within reflective structure 12 outer surfaces, can improve the radiating effect of light fixture, and the firm structure of fluorescent tube 1 again prevents that fluorescent tube 1 is out of shape easily and causes damage.Fluorescent tube 1 two ends adopt sealant sealing to irritate, and fluorescent tube is sealed fully, further improve moistureproof effect.
The utility model LED lamp is used for freezing illumination, and for example refrigerator illumination can improve the middle brightness of refrigerator, improves the whole uniformity of light in the refrigerator, thereby optimizes the effect of illumination.And the good seal performance of this LED lamp is applicable in the environment of high humility.
