Improve the LED desk lamp lampshade of light efficiency
The utility model relates to a kind of light fixture, especially LED desk lamp lampshade.
The white light of LED add the luminous general employing direct current of LED, so light does not have stroboscopic according to reaching its maturity at present; In the spectrum that LED produced, there is not simultaneously ultraviolet ray; Infrared ray and radiation are typical green illuminations, thus on the market application of LEDs do desk lamp illumination; Because price present stage of the LED lamp pearl of desk lamp illumination is higher relatively, makes the sale of product be restricted.How, vast pin expense person is accepted, just our problem anxious to be solved at present at the cost of same brightness decline low production.
Summary of the invention
The purpose of the utility model provides a kind of LED desk lamp lampshade that improves light efficiency, and the quantity that under the prerequisite that does not reduce desk lamp use brightness, reduces LED is to reduce cost, and is simultaneously more energy-conservation.
The utility model is to realize above-mentioned purpose like this:
Improve the LED desk lamp lampshade of light efficiency, comprise lampshade and be installed in the LED lamp body in the lampshade, be fixed with reflection recess in the said lampshade, the inner surface of reflection recess is provided with reflective surface, setting-in LED lamp body in the reflection recess.
Wherein, said reflection recess is made up of the buckling groove and the reflective side plate that are used to clamp the LED lamp body.
Wherein, reflection recess and lampshade bottom surface are fixed, and have outside diffuser socket and the reflection recess.
Wherein, it is one-body molded that said lampshade and reflection recess adopt section bar.
Wherein, the opening end of said reflection recess is provided with the mounting groove that is used to install diffuser, and diffuser and mounting groove matching and fixing are arranged.
The beneficial effect of the utility model is: the utility model is simple in structure; But reflection recess and LED lamp body are installed in direct convenience ground in lampshade; Perhaps reflection recess and lampshade are made into an integral body; Be as good as from profile and common desk lamp lampshade, owing to designed the groove that the reflection of tool light is arranged and help heat sinking function in the lamp body, not only energy-conservation than fluorescent tube desk lamp and common osram lamp desk lamp; And improves more than 30% than common LED desk lamp (co-altitude relatively) illuminance, also there is better heat radiation the while when LED is luminous.Being that said structure is simple in addition installs easily.Therefore have very strong practicality and promotional value, can be widely used in family, office space etc.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified:
Fig. 1 is the three-dimensional broken away view of first kind of embodiment of the utility model;
Fig. 2 is the three-dimensional broken away view of second kind of embodiment of the utility model.
The specific embodiment
Referring to figs. 1 through Fig. 2, improve the LED desk lamp lampshade of light efficiency, comprise lampshade 1 and be installed in the LED lamp body 2 in the lampshade 1 that be fixed with reflection recess 3 in the said lampshade 1, the inner surface of reflection recess 3 is provided with reflective surface, setting-in LED lamp body 2 in the reflection recess 3.Owing to designed the groove that the reflection of tool light is arranged and help heat sinking function in the lamp body; Not only energy-conservation than fluorescent tube desk lamp and common osram lamp desk lamp; And compare illuminance than common LED desk lamp co-altitude and improve more than 30%, better heat radiation is arranged when also LED is luminous simultaneously.Being that said structure is simple in addition installs easily.Therefore have very strong practicality and promotional value, can be widely used in family, office space etc.
Installation for the ease of LED lamp body 2; Said reflection recess 3 is made up of the buckling groove 31 and the reflective side plate 32 that are used to clamp LED lamp body 2, and is as long as lamp plate is inserted along buckling groove 31, convenient and swift during installation; And can make lamp plate well contact with reflection recess 3, also help heat radiation.
Because LED lamp pearl is a kind of spot light, its inside is provided with reflector etc., the light that penetrates by LED lamp pearl so relatively concentrate and brightness higher, be applicable to that in order to make it desk lamp to produce comparatively soft light, can be provided with diffuser 4.The utility model is that reflection recess 3 is fixed with lampshade 1 bottom surface, has outside diffuser 4 sockets and the reflection recess 3.
Be further simplified manufacturing technique, said lampshade 1 adopts section bar one-body molded with reflection recess 3.When being shaped, can be used to install the mounting groove 33 of diffuser 4 equally in the opening end moulding simultaneously of reflection recess 3, diffuser 4 and mounting groove 33 matching and fixing.
Certainly above-mentioned structure just supplies those skilled in the art's reference, and substituting of other modes can also be arranged in actual the use, but the above-mentioned protection domain that all should belong to the utility model that substitutes.
