Abstract
The utility model relates to the technical field of light-emitting diode (LED) light sheets, in particular to a railway signaling LED point source light sheet which comprises an aluminum substrate, a main lamp LED chip set and an auxiliary lamp LED chip set are arranged on the aluminum substrate in parallel, the LED chip sets are electrically connected with a point source light welding spot A, and the auxiliary lamp LED chip set is electrically connected with a point source light welding spot B. The railway signaling LED point source light sheet is simple in structure, reasonable in arrangement, and long in service life.
Description
Technical field
The utility model relates to LED lamp chip technology field, particularly a kind of railway signal LED point-source light sheet.
Background technology
LED, long and cause people's extensive concern with its environmental protection, life-span, along with LED technology ground is constantly ripe, every field such as extensive use indication, illumination.Railway signal LED lamp promptly is wherein a kind of, and existing railway signal LED lamp lamp sheet generally comprises aluminium base, is packaged in the some led chips on the aluminium base, and described led chip is connected in series by lead.Be provided with like this, have following deficiency and defective: there is optical attenuation in led chip, and phenomenons such as dead lamp will cause the situation of the not enough and dead lamp of whole lamp brightness, like this so be necessary to carry out architecture advances to having LED lamp sheet now.
The utility model content
The purpose of this utility model is at the defective of prior art and deficiency, a kind of compact conformation is provided, is provided with rationally, decay or the dead low LED point-source light sheet of lamp phenomenon incidence.
For achieving the above object, the utility model is by the following technical solutions:
A kind of railway signal LED point-source light sheet described in the utility model, comprise aluminium base, be provided with king light led chip group and secondary lamp led chip group on the described aluminium base side by side, described king light led chip group is electrically connected with the solder joint A that lights a lamp respectively, and described secondary lamp led chip group is electrically connected with the welding point B of lighting a lamp respectively.
Further, described king light led chip group and secondary lamp led chip group be arranged in parallel, and the distance between king light LED chipset and the secondary lamp led chip group is less than 2mm.
Further, described king light led chip group is connected in series by a plurality of led chips.
Further, described secondary lamp led chip group is connected in series by a plurality of led chips.
The utility model beneficial effect is: be provided with king light led chip group and secondary lamp led chip group on the aluminium base described in the utility model side by side, under the normal condition, the work of king light led chip group, behind king light led chip group optical attenuation or dead lamp, secondary lamp led chip group startup work does not influence the utility model operate as normal.The utility model is simple in structure, and long service life is set rationally.
Description of drawings
Fig. 1 is an overall structure schematic diagram of the present utility model.
Among the figure:
1a, 1b, the welding point B of lighting a lamp; 2a, 2b, solder joint A lights a lamp; 3, aluminium base;
4, king light led chip group; 5, packaging plastic; 6, secondary lamp led chip group.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
As shown in Figure 1, a kind of railway signal LED point-source light sheet described in the utility model comprises aluminium base 3, is provided with king light led chip group 4 and secondary lamp led chip group 6 on the described aluminium base 3 side by side, and by packaging plastic 5 encapsulation.
Described king light led chip group 4 is connected in series by a plurality of led chips, described king light led chip group 4 respectively with the solder joint A2a that lights a lamp, 2b is electrically connected.Described secondary lamp led chip group 6 is connected in series by a plurality of led chips, described secondary lamp led chip group 6 respectively with the welding point B 1a that lights a lamp, 1b is electrically connected.Described king light led chip group 4 and secondary lamp led chip group are driven by independent constant current branch road respectively, under the normal condition, 4 work of king light led chip group, when optical attenuation appears in king light led chip group 4, phenomenons such as dead lamp will automatically switch to secondary lamp led chip group 6, secondary lamp led chip group 6 work, thereby do not influence the utility model work, prolonged the utility model service life.
Need to prove that described king light led chip group 4 and secondary lamp led chip group 6 be arranged in parallel, and the distance between king light led chip group 4 and the secondary lamp led chip group 6 is less than 2mm.Be provided with like this, king light led chip group 4 and secondary lamp led chip group 6 all can be gathered on the focus of lens, help having improved the utilization rate of light source like this.
The above only is a better embodiment of the present utility model, so all equivalences of doing according to the described structure of the utility model patent claim, feature and principle change or modify, is included in the utility model patent claim.
