Embodiment
Below in conjunction with accompanying drawing 1 to 3, and embodiment is described further the utility model.
Embodiment: see Fig. 1.
The LCDs that a kind of light inlet is adjustable, comprise backlight module, described backlight module comprises light guide plate 1 and is arranged on the LED module of light guide plate 1 side, described LED module comprises LED 21 and lens 3, described lens 3 are between LED 21 and light guide plate 1, described light guide plate 1 is provided with the shrinkage pool 11 for accommodating LED 21 near the side of LED 21, the end face of described shrinkage pool 11 concaves formation concave curved surface 12, the light that LED 21 sends focuses on through lens 3 and forms directional light, and directional light is dispersed through concave curved surface 12 and injected light guide plate 1.
The technical program is when designing, and optimize the light emitting path of LED 21, LED 21 is pointolite, in current backlight module, LED 21 light directly projects in light guide plate 1, then projected away by light guide plate 1 by great majority, due to pointolite project time, directivity is poor; Cause the light guide plate 1 one end brightness near LED 21 larger, less away from one end brightness, in order to allow the maximized other end that can be transferred to light guide plate 1 of light, improve uniformity of luminance, the technical program devises light penetration system, lens 3 coordinate with concave curved surface 12, lens 3 are collector lens, as convex lens etc., when specifically arranging, fixing ear 31 is extended in the side of lens 3, is fixed on a fixed head 32 by fixing ear 31, and lens 3 can according to width adjustment distance (see Fig. 2) of light guide plate between LED 21 and light guide plate 1.One can certainly be arranged in concave curved surface 12 and be embedded ring, lens 3 are fixed on and be embedded in ring.
Further, described LED module comprises the circuit board 2 for mounted LED lamp 21, and the surface of described circuit board 2 is provided with reflector layer (not shown in FIG.).
Reflector layer is set, improves light utilization efficiency.
Further, the side of described light guide plate 1 is provided with reflector, and reflector and light guide plate 1 are fitted.
Reflector is set in the side of light guide plate 1, the light projected from the side is reflected back, improve light utilization efficiency.Reflector can certainly be set in the bottom surface of light guide plate 1.
Further, described lens 3 are convex lens.
