[specific embodiment]

Also in conjunction with the accompanying drawings the utility model is described in further detail below by specific embodiment.

Embodiment one: direct-injection type is adopted in the installation of the LED element group that this is routine, and as shown in Figure 1, LED does not have part 12 and is vertically mounted on the pcb board 11, and pcb board is located on the Lamp base.Undersurface of bottom disc has reflection function, each is organized between the LED the reflective partition 13 with surface reflection and separates, and makes it the light of LED is produced effects such as reflection, scattering, thereby makes the whole LED lamp panel can produce uniform light, after passing through printing opacity or semi-transparent film 2 again, light is more even.As shown in Figure 2, on the film 2, perforate on the lamp panel 1 outer rim relevant position, film can use glue bolt 30 to fix in perforate, and is easy to change or disassemble cleaning.Shown in Fig. 3,4,5, film can be made different shape according to lamp panel, be printed to shades of colour and pattern, as basketball, football, cartoon figure etc., produces decorative effect, increases temperament and interest.
