The specific embodiment

Hereby relevant detailed content of the present utility model and technical descriptioon now are described further with embodiment, but will be appreciated that, these embodiment are the usefulness for illustrating only, and should not be interpreted as the restriction that the utility model is implemented.

See also Fig. 1, Fig. 2, Fig. 3 and shown in Figure 4, it includes the utility model: a lampshade 20, a diffusion barrier 10 and a circuit board 30; The inside of this lampshade 20 is provided with light tight a plurality of mirror surface 22, and this mirror surface 22 can be so that each other not scattering and in order to reducing the scattering of light of the light source between contiguous, and isolates whereby a plurality of light cups 23.

This light cup 23 designs for spill, and this light cup 23 has an accommodation space 24, this accommodation space 24 is provided with at least one light emitting diode 40, the bottom of this accommodation space 24 is provided with a perforate 28, this at least one light emitting diode 40 passes this perforate 28 and is electrically connected on this circuit board 30, this accommodation space 24 is in having an opening 27 away from these perforate 28 parts, the plane at these opening 27 places may be defined as a light output face 271, and the length L of this opening 27 can equal this opening 27 to the distance D (as shown in Figure 3) of this perforate 28, and reaches best light design path.

In addition, this accommodation space 24 is in a reflecting surface 241 that can form vertical this light output face 271 near these opening 27 places, and this reflecting surface 241 can limit to light path, and can avoid scattering to reduce loss of light source.

In addition, these lampshade 20 whole coatings one aluminize 201, and can be silvery white, this is aluminized and 201 can increase reflection, so the utility model is in the application of illumination, except reducing the scattering of located adjacent one another this light emitting diode by this mirror surface 22, more the spill by this light cup 23 designs, strengthening the light concentration degree of this light emitting diode 40, and the wall of cup of this light cup 23 is designed to have a plurality of reflective burrs 21, and this reflective burr 21 can be strengthened reflectance.
