Scope.
Referring to Fig. 1, providing a kind of baggage compartment lamp 4 for the utility model, it is applied to vehicle (tricycle, car, goods
The automobiles such as vehicle) top in boot, comprising: the shell that is fixed in the boot simultaneously forms confined space with the shell
Lampshade (as shown in figure 3, the shell that is fixed in the boot and lampshade for forming confined space with the shell is embedded in
In interior plaque 6, which is set to outside interior plaque 6, and screw can be used in the light transmission lampshade divergent rays shell and lampshade
Connection or snap fit connection), lamp group 5 is set in the lampshade, the lamp group includes LED module 1 and light pipe 2, the LED
Module 1 connects the LED module 1 for providing light source, one end of the light pipe 2, wherein the light pipe 2 is Transparent color
Bar-shaped body, for guiding light source；And the reflective tape 3 that the top even print of the light pipe 2 has reflective material to be formed,
To reflect the brightness for improving light pipe 2 with refractive Iy.
In the present embodiment, the reflective tape 3 is along 2 even print of light pipe of the bar-shaped body in the light pipe
The back side of installation, when convenient for lamp group installation, one lamp group can avoid transparent light guide since mounting surface is uniformly coated with reflective material
It manages comprehensive full angle freely to shine, the two, equal-wattage LED module can be improved light pipe using the reflective tape of reflective material
Brightness, more preferably meet user demand.According to the type of the vehicle size for adjusting baggage compartment lamp corresponding to shape, in order to luggage
Case lamp is installed on vehicle.
Wherein, the LED module 1 includes LED circuit board 11 and protective shell 12, installs LED circuit in the protective shell 12
Plate 11 and the LED circuit board 11 emit light source along 12 export direction of protective shell.
The LED module also includes heat-sink unit 13, and the heat-sink unit 13 is installed on the LED circuit board 12 and fixes
On the protective shell 12.
In the present embodiment, the heat-sink unit 13 is aluminum alloy heat sink, can be to LED circuit board by the cooling fin
It radiates, can guarantee its permanent work, it can the fast temperature for reducing LED circuit board generating heat.
The reflective tape is along the light pipe even print of the bar-shaped body in the light pipe mounting surface or mounting surface
Inside, wherein reflective tape is printed on the back side of light pipe in the present embodiment, that is, the installation site of opposite light pipe is mounting surface,
And as shown in Figure 1, on the inside of the preferred mounting surface of the reflective tape, that is, reflective tape is printed on the inner surface of light pipe, will not with when
Between elapse discoloration, alternatively, there is dust to be attached on reflective tape.
The shape of the reflective tape 3 and the light pipe of bar-shaped body match, if reflective tape 3 is bar-shaped body,
Its corresponding reflective tape 3 is also strip, which is preferably bar shaped cylinder, is conducive to the transmission and diverging of light source.And
The printing width of the reflective tape 3 is no more than the half of the light pipe perimeter, that is, area accompanying by reflective tape is no more than bar shaped
The half of cylinder ignition-face area, due to the wide shadow surface that will directly affect light pipe in the broadband of reflective tape 3, to influence to shine
Degree.
The both ends of the light pipe 2 are respectively correspondingly connected with a LED module 1, wherein one end connection LED can be used in light pipe 1
Module 1 can also all be correspondingly connected with LED module 1 at the both ends of light pipe 2, due to the light emission luminance of the LED module 1 of equal-wattage
It is in relaxation phenomenon as 2 length of light pipe increases, is greater than 1 light source transmission range of LED module when 2 length of light pipe is too long, directly
The light emission luminance from entire effect lamp group is connect, in order to enable light pipe brightness uniformity, it can be according to the demand of user at its both ends
Each setting LED module 1 effectively solves the problems, such as light pipe length issue and bring brightness decay and brightness irregularities.
Corresponding boss is arranged for the protective shell outlet of the LED module 1 or link slot is used to dock the end of the light pipe 2
Portion connects light pipe 2 by setting boss or link slot, it is ensured that light pipe 2 and LED module 1 are closely coupled, and light leakage will not occur
Phenomenon.
The LED circuit board 11 includes LED light source and circuit board, and the LED light source is set on circuit board, and the electricity
The plate matter of road plate is made of organic glass or PCBA, and organic glass is to use polymethyl methacrylate (PMMA) plate
Organic glass, with splendid weatherability, higher surface hardness and lustrous surface and preferable high temperature resistance make it
Machining accuracy greatly improves, but also can produce the pattern and moulding more exquisite than traditional approach.Wherein, the LED light source
Power be 5~10W, when LED light source power is more than 10W, excessive to will lead to light pipe brightness too strong, when LED light source power not
It is too low to reduce light pipe brightness to 5W.
In conclusion setting light pipe and LED light source in the baggage compartment lamp, LED light source is utilized with the light pipe side of combining
Formula, it is of simple structure and low cost, convenient for meeting the various demands of user；It is illuminated by using the mode of this non-direct projection of light pipe
Licence plate, it is ensured that the brightness of baggage compartment lamp is uniformly distributed along light pipe to be irradiated；Simultaneously as light pipe interior surface is uniform
It is printed with reflective tape, under the situation for not increasing power consumption, luminosity in light pipe is increased into light pipe by reflection, refractive Iy
Brightness improves the uniformity and brightness of lamp group.So the utility model effectively overcome various shortcoming in the prior art and
Has high industrial utilization value.
The above embodiments are only illustrative of the principle and efficacy of the utility model, and not for limitation, this is practical new
Type.Any person skilled in the art can all carry out above-described embodiment under the spirit and scope without prejudice to the utility model
Modifications and changes.Therefore, such as those of ordinary skill in the art without departing from the revealed essence of the utility model
All equivalent modifications or change completed under mind and technical idea, should be covered by the claim of the utility model.
