Can, according to given design parameter, known optical computing formula or software be utilized to carry out the shape and size of accurate Calculation lens to realize basic uniform Light distribation.
Fig. 7-9 shows the shape of the lens according to an embodiment of the present disclosure.The inwall 41 of lens 4 is defined as half ellipsoidal surface 411, by calculating or emulate the outer wall that can obtain and be formed by free form surface 421.Because the substrate 21 that holds in lens 4 inner chamber and the light emitting diode on it have certain thickness, in order to substrate 21 can be encased on the thickness direction of substrate, lens 4 are also formed with transition portion, comprise the transition portion 422 on outer wall and the transition portion (not shown) on inwall.This transition portion is positioned at the centre position of the semielliptical shape/free form surface of inside and outside wall.Experiment proves, the lens with this transition portion still can realize good Light distribation effect.The lens of this shape can obtain around the basic uniform Light distribation around the longitudinal axis of bulb, thus the illumination effect of simulate halogen capsule lamp.
Figure 10-12 shows the shape of the lens according to another embodiment of the present disclosure.The outer wall 42 of lens is defined as hemisphere face, by calculating or emulate the inwall 413 of curved surface of can gaining freedom.The lens of this shape can obtain around the basic uniform Light distribation around the longitudinal axis of bulb equally, thus the illumination effect of simulate halogen capsule lamp.The lens inwall of this shape also can be formed the transition portion of non-optical at the mid portion of free form surface, to increase the lens lumen width in substrate thickness direction.The lens with hemispheric outer wall 42 can close with the matching form of shell 1 better, because the cross section of shell 1 is generally circle.Like this, the bulb of outward appearance smoothness more attractive in appearance can be obtained.Also can design the lens of the inner and outer wall with other shape, such as, inwall 41 can be selected to comprise half ellipsoidal surface 411 or free form surface, and outer wall 42 comprise free form surface or hemisphere face.
The height stretched out from shell due to the substrate 21 of LED component 2 is higher, and the height of the lens of the inside and outside wall of the hemispherical or semielliptical shape of standard may be not enough to make its inner chamber cover substrate 21.Therefore, according to an embodiment of the present disclosure, as depicted in figure 8, the bottom 44 that has the column of certain altitude can be extended downwards on the basis of the shape 43 reaching best optical effect of the above-mentioned calculating of lens, cover substrate 21 completely to enable the inner chamber of lens 4.Alternatively, can arrange on the inwall 41 of lens 4 and there is groove 412, for holding and the edge of fixing base 21.Like this, the Outside Dimensions of substrate 21 can be greater than the inner chamber of lens 4, thus when ensureing can arrange larger substrate 21 when not increasing lens sizes, this means to arrange more or more powerful light emitting diode on the base plate (21, to improve the optical output power of bulb.
