The specific embodiment

Below, cooperate the accompanying drawing of each preferred embodiment of the utility model to be described further again, so that the personage who is familiar with the utility model correlation technique can be implemented according to this according to the statement of this specification:

At first, please cooperate and consult Fig. 1 to shown in Figure 4, according to light-emitting device 100 preferred embodiments of the present utility model, it mainly comprises: circuit substrate 10 is equipped with two or more illuminators 11 on it; Two or more

optical lenses

20,20 groups of light-emitting area front ends that are located at each illuminator 11 of circuit substrate 10 of optical lens; Capping plate 30 can be single distribution and most less illuminators 11 of spacing so that form a kind of strip simultaneously with the nested in the lump location of aforementioned two or more optical lenses 20.

Continue to describe in detail the utility model part structural feature:

This circuit substrate 10, be to be strip, and adopting at interval along long side direction, suitable distance is provided with two or more illuminators 11, these two or more illuminators 11 are that the single file arrangement is strip, and this circuit substrate 10 is provided with most lockholes 12 between some predetermined adjacent illuminator 11; Wherein, aforementioned illuminator 11 is to adopt a kind of light emitting diode (LED);
