Abstract
The utility model relates to an indicating lamp cover plate for a vehicle. The cover plate comprises a top plate and side plates on four sides of the top plate; the top plate is provided with more than one light transmitting slot; a light diffusion layer is fixed to the upper end face of the top plate; and the light diffusion layer covers the light transmitting slot. When the light passes through the cover plate, the light diffusion layer ensures the light to be diffused to all direction so that the focus points of the light are eliminated and the uniformity of the light and the brightness of the dark illumination area are improved; therefore, the brightness of the dark area can be improved without increasing the current of an LED (Light Emitting Diode) light source, thus protecting the LED light source, prolonging the service life of the LED light source, ensuring the patterns or letters on the indicating lamp to have more lifelike effect, and improving visual effect of the appearance.
Description
Technical field
The utility model relates to a kind of automobile-used indicator lamp cover plate, belongs to the indoor indicator lamp technical field of motor vehicle.
Background technology
Be typically provided with indicator lamps such as water temperature, machine oil, parking brake, storage battery ABS, safety belt and air bag on the indoor instrument board of motor vehicle; Also have some like power supply indicators such as press button, emergency warning lamp, electric window switch and door interlock switches, understand the present situation that vehicle is respectively controlled the position through each indicator lamp.Led light source is that LED source has light source utilization rate height, long service life, the characteristics that the exciter response time is short, more and more light sources as the indoor indicator lamp of motor vehicle.Present indicator lamp by lamp housing, be installed in the led light source in the lamp housing and the cover plate that is installed on the lamp housing constitutes, make light see through cover plate and show.Observe the indicator lamp of difference in functionality for coming into plain view, the cover plate of indicator lamp also is furnished with corresponding identification pattern or letter usually, and light sees through and leads to the light slotted eye on the cover plate with explicit identification pattern or letter, makes the driver see the signal that is shown.Because the light of indicator lamp is outwards to distribute from light source center; Therefore light can produce focus point; The brightness of illumination dark space is not high, not only need improve the brightness of dark space through the electric current that improves led light source, and reduce the service life of led light source; On the other hand, also cause light can not reach uniformity preferably.
Summary of the invention
The purpose of the utility model provides a kind of brightness that improves the illumination dark space, improves led light source service life, improves the inhomogeneity automobile-used indicator lamp cover plate of light.
The utility model is that the technical scheme that achieves the above object is: a kind of automobile-used indicator lamp cover plate; Cover plate comprises top board and is positioned at top board side plate all around; Top board is provided with more than one logical light slotted eye; It is characterized in that: the upper surface of said top board is fixed with light diffusion layer, and light diffusion layer covers on each logical light slotted eye.
The utility model is fixed with light diffusion layer in the top board upper surface of cover plate, owing to light diffusion layer covers on each logical light slotted eye, when light passes through cover plate; Through light diffusion layer light is to all the winds scattered, not only eliminated the focus point of light, and improve the uniformity of light and the brightness of illumination dark space; Therefore can avoid improving the brightness of dark space through the electric current that improves led light source; Thereby protected led light source, prolonged the service life of led light source, light is behind light diffusion layer; Make pattern or alphabetical effect on the indicator lamp more true to nature, can improve the outward appearance visual effect.
Description of drawings
Below in conjunction with accompanying drawing the embodiment of the utility model is made further detailed description.
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the another kind of structural representation of the utility model.
Wherein: the 1-lamp housing, the 2-LED light source, the 3-cover plate, 31-leads to light slotted eye, 32-snap ring, 33-side plate, 34-top board, 4-light diffusion layer, 5-light-transmissive film.
The specific embodiment
See shown in Figure 1ly, the automobile-used indicator lamp cover plate of the utility model, cover plate 3 comprise top board 34 and the side plate 33 that is positioned at around the top board 34; Top board 34 is provided with more than one logical light slotted eye 31, and this logical light slotted eye 31 is to form independently a pattern or a literal, or constitutes independently pattern or literal through a plurality of logical light slotted eyes 31; The upper surface of top board 34 is fixed with light diffusion layer 4, and light diffusion layer 4 covers on each logical light slotted eye 31, and the light diffusion layer 4 of the utility model can adopt optical diffusion film; Directly be bonded on the top board 34, or see shown in Figure 2ly, the light diffusion layer 4 of the utility model is coated on the light-transmissive film 5; And light-transmissive film 5 is fixed on the top board 34; Spread through 4 pairs of light of light diffusion layer, and dwindle the light in the dark space and the clear zone of illumination, make that through light diffusion layer 4 pattern or letter on the indicator lamp are more true to nature.
See Fig. 1, shown in 2; The led light source 2 of the utility model indicator lamp is installed in the lamp housing 1; Connect in succession and the snap ring 32 of cover plate 3 through its side plate 33 bottoms and lamp housing 1 are removable, or side plate 33 bottoms directly are welded on lamp housing 1 top and directly fixing, when led light source 2 is lighted; The light that led light source sends makes light improve the uniformity of light to irradiation all around through after leading to light slotted eye 31 and light diffusion layer 4.
