Embodiment 1

[0017] Such as figure 1 , figure 2 , image 3 with Figure 4 As shown, the present invention uses a light box 1 and an LED light bar 2. The light box 1 is composed of a front light-transmitting plate 3 and a surrounding frame 4. The LED light bar 2 is placed in the light box 1. According to the size of the light box 1, more light boxes can be placed in the light box 1. The LED light bar 2 can be arranged horizontally or vertically. The LED light bar 2 includes an LED light 5 and a substrate 6. The LED light 5 is fixed on the substrate 6, and the LED light 5 in the LED light bar 2 is connected in series. The driving circuit is connected to the power supply. The LED lamp 5 includes an LED lamp bead 7, a lens 8 and an LED lamp shade 9. The LED lamp bead 7 is welded on the substrate 6, the lens 8 is embedded in the LED lamp shade 9, and the LED lamp shade 9 is glued and fixed on the substrate 6. The shape of the lens 8 is basically a truncated cone shape. At the large round end of ...

Abstract

The invention discloses an LED advisement lamp case relating to an advisement illuminating device and mainly solving the problems of higher cost and complex manufacture procedures of the traditional LED lamp case. A lamp case and an LED lamp strip are adopted, wherein the LED lamp strip comprises an LED lamp and a substrate, the LED lamp is fixed on the substrate, and LED lamps in the LED lamp strip are serially connected and then connected with a power supply through a drive circuit. The LED advisement lamp case is characterized in that an LED lamp comprises an LED lamp bead, a lens and an LED lamp shade, wherein the LED lamp bead is welded on the substrate, the lens is embedded in the LED lamp shade which is adhered and fixed on the substrate, the lens is basically shaped as a circular truncated cone, the large circular end of the lens is provided with a cylindrical body, parallel convex edges are uniformly arranged on the front end face of the cylindrical body, cross sections of the convex edges are shaped as arcs, the middle of the small circular end of the lens is provided with a square hole, the top of the square hole is provided with a convex spherical surface, and the LED lamp bead is placed in the square hole. The invention is mainly used in advisement communication.

Description

Technical field [0001] The present invention relates to advertising lighting equipment, especially LED advertising light boxes. Background technique [0002] The existing advertising light boxes generally use fluorescent tubes as the light source. Fluorescent tubes have low luminous efficiency, short service life and uneven light emission. Therefore, LED lights are widely used in advertising light boxes. They are ultra-thin, safe, low power consumption, and energy-saving. Such advantages, but when it is used in a light box, the light is uneven, the light in the light box closer to the LED light is brighter, and the light in the far place is darker, and the quality of the light box advertising picture is relatively poor. In order to solve this problem, the patent publication number: CN 101089925A discloses a light-emitting diode advertising light box, which has a whole light guide plate installed in the light box, and the light emitted by the light-emitting diode guides light thro...
