Abstract

The utility model relates to a lamp tube structure with multiple lampshades. An auxiliary lampshade is additionally arranged to enlarge the light-emitting angle of LED (light-emitting diode) particle light, further eliminates high light spots generated by an LED particle on a main lampshade, and is matched with the main lampshade to generate a softer and more uniform light shape. The lamp tube structure includes a heat dissipation part, a light-emitting module and the main lampshade, wherein the light-emitting module is adhered to the heat dissipation part; at least one auxiliary lampshade is arranged between the main lampshade and the light-emitting module, covers the light-emitting module, and is covered by the main lampshade, so that light emitted by the light-emitting module has the light-emitting angle enlarged by the auxiliary lampshade actively, and the high light spots on the main lampshade are eliminated; the multiple lampshade design of the auxiliary lampshade and the main lampshade can enable the light shape to be softer and more uniform.

Description

The lamp tube structure of the multiple lampshade of tool

Technical field

The utility model refers in particular to a kind of diode lighting tube structure that no bright spot is provided and possesses preferable smooth shape about the lamp tube structure of the multiple lampshade of a kind of tool.

Background technology

Along with the light emitting diode of high-luminous-efficiency and low power consuming is popularized gradually; Now illuminating lamp tube many with light emitting diode as main luminescence component; But, during the running of light-emitting diodes tube particle, most likely produce high heat energy; If can't get rid of immediately, the anxiety of the light-emitting diodes of burning tube particle and perimeter component thereof is arranged then.

Early stage typical light-emitting diode lamp tube member mainly by the heat radiator body 1 that constituted by the aluminium extruded material and one and this heat radiator body 12 of illuminating module of combining closely form; In recent years; Adjust light shape for asking preferable bright dipping light shape most likely to set up a lampshade 3 (shown in the 1st to 2 figure), the light that this illuminating module 2 is sent directly spreads equably through independent lampshade 3 and forms the wide and uniform fluorescent tube illuminating effect of light shape of illumination zone.

So; Through the structural design of the aforementioned independent lampshade of setting up 3, can obtain big illumination zone and uniform light shape really, but; During set light-emitting diodes tube particle 21 sends on this illuminating module 2 this lampshade 3 of light penetration; Because of its light transmittance can't reach 100%, and can produce 20%～30% light loss, find after deliberation; When the position of light-emitting diodes tube particle 21 and this lampshade distance more little (weak point); The light loss that causes is less, but can be because of the lighting angle θ 1 limited (θ 1=120 degree) of light-emitting diodes tube particle 21, cause the light of light-emitting diodes tube particle 21 too concentrate on its correspondence the lampshade zone and produce tangible highlight (high light) (as shown in Figure 1) and will solve the generation of bright spots and make fluorescent tube light shape comparatively more even; Then certainly will need to strengthen the distance of (length) light-emitting diodes tube particle and lampshade; But this mode also can cause the excessive problem of aforementioned light loss except that meeting compression puts in place at the illuminating module installing space (as shown in Figure 2) of the power supply unit P of side in addition, when serious even can produce the light loss of height to 50%～60%.

In sum, how effectively to reduce the fluorescent tube light loss and promote the even light shape of fluorescent tube awkward situation that traditional lamp tube structure of light-emitting diode can't be taken into account seemingly, therefore, how taking into account even light shape and reducing light loss is the problem of being studied intensively by the utility model.

Summary of the invention

The main purpose of the utility model is at the lamp tube structure that the multiple lampshade of a kind of tool is provided; Set up the lighting angle that a secondary lampshade initiatively adds big light-emitting diodes particle light; And then eliminate the diode particle and on the king light cover, produce outside the highlight, also can with this king light cover more soft and more uniform light shape of generation of arranging in pairs or groups; The diode lamp tube of the utility model comprises:

One radiating part, an illuminating module and a king light cover; This illuminating module is attached to this radiating part, and this king light cover is assembled into one with this radiating part mutually, and is provided with at least one secondary lampshade between this king light cover and this illuminating module; This pair lampshade covers this illuminating module, and this king light cover covers this pair lampshade;

Thus, the light that this illuminating module is sent out can initiatively enlarge the highlight that its lighting angle is eliminated the king light cover through this pair lampshade, and the multiple modulation of secondary lampshade and king light cover is covered with meter and can obtains soft and more uniform light shape.

Wherein, this pair lampshade inner surface, outer surface or surfaces externally and internally can be coated with at least one thin-film body, are used for filtering different wave length coloured light, and then control the coloured light that this diode lamp tube sends out and eliminate harmful light.

Wherein, these pair lampshade inner edge two sides are respectively equipped with at least one embedding portion, are used for compacting to live this illuminating module rim.

Wherein, under this radiating part the surface be provided with two keep suitable distance each other embeded slot; And this king light cover, its two side is arranged with at least one assembled portion, and this assembled portion inserts this embeded slot and compacting firmly should the pair lampshade simultaneously.

Wherein, this assembled portion comprises: at least onely be used for inserting the stiff end of this embeded slot and the compacting end that this pair lampshade outside rim is lived at least one responsible compacting.
