Detailed description of the invention
For understanding content of the present utility model further, by reference to the accompanying drawings the utility model is described in detail.
Composition graphs 1, Fig. 2, Fig. 3, Fig. 4 and Fig. 5, a kind of high illumination projecting lamp with secondary reflecting part of the present utility model, comprise lens 1, speculum 5 and light source, also comprise secondary reflecting part 4, secondary reflecting part 4 is positioned near speculum 5 upper end open, secondary reflecting part 4 has the reflector 42 of arch, for collecting the lateral light sent with the veiling glare of reflex reflector 5 reflection and light source, the one side that this reflector 42 is relative with light source is reflecting surface 41.
Below in conjunction with embodiment, the utility model will be further described.
Embodiment 1
As shown in Figure 1, a kind of high illumination projecting lamp with secondary reflecting part of the present embodiment, comprise lens 1, support 2, speculum 5, light source mount pad 3 and light source, light source mount pad 3 is located at the bottom of speculum 5, light source is installed on light source mount pad 3, and be positioned at one of them focus place of speculum 5, in order to improve reflecting effect, speculum 5 adopts compound ellipsoid structure.The upper end open place of speculum 5 is located at by support 2, and is connected between lens 1 and speculum 5, and lens 1 are arranged on support 2 top, employing be the good aspheric surface convex lens of spotlight effect.Due to light fixture use time, the light that light source sends reflects through speculum 5, part reflection ray directly reflexes to lens 1 and penetrates, the outside that another part reflection ray then reflexes to lens 1 cannot be penetrated and throw light on, and which results in quite a few lateral light or veiling glare can not get effectively utilizing and being wasted.Therefore the present embodiment is also provided with secondary reflecting part 4, and secondary reflecting part 4 is positioned near speculum 5 upper end open, is clipped between speculum 5 and support 2, and is bolted fixing.Secondary reflecting part 4 has two, be separately positioned on the both sides up and down of the focus of speculum 5, for collecting the lateral light sent with the veiling glare of reflex reflector 5 reflection and light source, these two secondary reflecting parts 4 both can be the overall structures (as shown in Figure 2) be made of one piece, and also can be the split-type structurals (as shown in Figure 3) that separate machined manufactures.
The secondary reflecting part 4 of the present embodiment has the arch reflector 42 (as shown in Figure 4) being more conducive to collect light, the one side that this reflector 42 is relative with light source is reflecting surface 41.Based on the mirror-reflection principle design of optics, reflecting surface 41 is formed by connecting by multiple reflective surface, and preferably adopts the little reflective surface that surface area is less, effectively can improve the utilization rate of invalid light, above-mentioned multiple reflective surfaces are step-like distribution, to control the reflection direction of invalid light more flexibly.
The secondary reflecting part 4 of the present embodiment both can be applied to distance light projecting lamp, also dipped beam projecting lamp can be applied to, all effectively can collect lateral light that light source sends and the veiling glare that speculum 5 reflects, and by these light reflections on speculum 5, the active component then again reflexing to lens 1 by speculum 5 realizes illuminating effect.When being applied to dipped beam projecting lamp, secondary reflecting part 4 can combine with shadow shield 6 and form an overall structure (as shown in Figure 4 and Figure 5), this structure both can realize the "cut-off"line clearly required by dipped headlights, and the veiling glare that the lateral light that can send light source again and speculum 5 reflect carries out secondary reflection again until it is utilized effectively by lens 1 injection.
Embodiment 2
A kind of high illumination projecting lamp with secondary reflecting part of the present embodiment, compared with embodiment 1, its difference is: the secondary reflecting part 4 of the present embodiment has one, be arranged on the side of the focus of speculum 5, which side being specifically arranged on speculum 5 then can be selected according to actual needs voluntarily.
In prior art, the light utilization efficiency of traditional projecting lamp generally only can reach about 40.5%, have the light of quite a few not to be utilized effectively and wasted by raw, and the illumination brightness that result in projecting lamp is not enough to some extent, can not meet the demand of client.Thus the utility model devises a kind of high illumination projecting lamp with secondary reflecting part, original projecting lamp basis has installed secondary reflecting part 4 additional, the lateral light that originally cannot obtain utilizing and veiling glare are again collected and utilized, compensate for the deficiency that existing projecting lamp illumination is inadequate, improve the effective rate of utilization of the light of about 15%-30%, illumination brightness increases greatly, can meet the requirement of client to illumination completely.And due to the reflective surface distribution on secondary reflecting part 4 of the present utility model many and close, the reflection direction of light is more accurate, and uniform illumination degree also promotes greatly.The WBR effect of projecting lamp is obtained for significant progressive and optimization, and its production and use cost but increase how many simultaneously, and very economical practicality is conducive to producing in batches.
Schematically above be described the utility model and embodiment thereof, this description does not have restricted, and also just one of the embodiment of the present utility model shown in accompanying drawing, actual structure is not limited thereto.So, if those of ordinary skill in the art enlightens by it, when not departing from the utility model and creating aim, design the frame mode similar to this technical scheme and embodiment without creationary, protection domain of the present utility model all should be belonged to.
